GLP-1: The Missing Link of Diabetes and Hypertension

An international team of researchers has finally cracked the puzzle of why so many patients with hypertension also have diabetes. Their discovery has shown that glucagon-like peptide-1 (GLP-1) couples the body’s control of blood glucose and blood pressure.

Senior Author Professor Julian Paton at the University of Auckland, said: “We’ve known for a long time that hypertension and diabetes are inextricably linked and have finally discovered the reason, which will now inform new treatment strategies.”

The study is published online in Circulation Research.

It has long been known that GLP-1 is released from the wall of the gut after eating and acts to stimulate insulin from the pancreas to control blood sugar levels.  However, the researchers found that GLP-1 also stimulates the carotid body, a chemoreceptor located in the neck.

Researchers used RNA sequencing to read all the messages of the expressed genes in the carotid body in rats with and without high blood pressure. This led to the finding that the receptor that senses GLP-1 is located in the carotid body, but less so in hypertensive rats.

David Murphy, Professor of Experimental Medicine from Bristol Medical School: Translational Health Sciences (THS) and senior author, explained: “Locating the link required genetic profiling and multiple steps of validation.  We never expected to see GLP-1 come up on the radar, so this is very exciting and opens many new opportunities.”

Professor Paton added: “The carotid body is the convergent point where GLP-1 acts to control both blood sugar and blood pressure simultaneously; this is coordinated by the nervous system which is instructed by the carotid body.”

Even when on medication, many patients with hypertension and/or diabetes are at high risk of life-threatening cardiovascular disease. This is because most medications only treat symptoms and not causes of high blood pressure and high sugar.

Professor Rod Jackson, an epidemiologist from the University of Auckland, said: “We’ve known that blood pressure is notoriously difficult to control in patients with high blood sugar, so these findings are really important because by giving GLP-1 we might be able to reduce both sugar and pressure together, and these two factors are major contributors to cardiovascular risk.”

Lead author Audrys Pauža, PhD student in the Bristol Medical School, added: “The prevalence of diabetes and hypertension is increasing throughout the world, and there is an urgent need to address this.

“Drugs targeting the GLP-1 receptor are already approved for use in humans and widely used to treat diabetes. Besides helping to lower blood sugar these drugs also reduce blood pressure, however, the mechanism of this effect wasn’t well understood.

“This research revealed that these drugs may actually work on the carotid bodies to enact their anti-hypertensive effect. Leading from this work, we are already planning translational studies in humans to bring this discovery into practice so that patients most at risk can receive the best treatment available.”

The research has also revealed many novel targets for ongoing functional studies that the team hope will lead to studies in human hypertensive and diabetic patients.

Air Pollution Linked to Hypertension

Chronic exposure to air pollution in the form of particulate matter contributes to the risk of cardiovascular and respiratory diseases, and in particular has been linked to hypertension, according to a study published in Scientific Reports.

Air pollution, accounting for more than 4.2 million deaths annually, is a significant health risk. The study assessed the impact of particulate pollution on the long-term incidence of hypertension in Spain, supporting the need to improve air quality to the extent possible in order to reduce the risk of cardiometabolic diseases among the population.

To this end, researchers have carried out a study, di@bet.es, which recruited 1103 participants aged 18–83. None of the participants presented with hypertension at the start of the study (2008–2010), and they were monitored until 2016–17. Participants were assigned air pollution concentrations for particulate matter, obtained through modeling and air quality readings. During this period, 282 cases of incident hypertension were recorded.

The study was carried out in collaboration with the air pollution department of the Research Centre for Energy, Environment and Technology (CIEMAT).

As explained by endocrinologist Sergio Valdés, “Several previous studies have described the short- and long-term association of ambient air pollutants with hypertension and blood pressure levels, but few studies have addressed the association between long-term exposure to these particles and the incidence of hypertension in a prospective manner. Therefore, the di@bet.es study has offered us the opportunity to do so in the Spanish population.”

Participants underwent a medical examination and had blood samples taken. They also answered questionnaires to obtain demographic information and variables such as smoking, exercise and diet.

Gemma Rojo, last study author, stated that “our data is consistent with a large body of evidence suggesting that air pollution may contribute to the pathogenesis of hypertension. It also supports the idea that the particulate component of air pollution is the greatest threat to the cardiovascular system.”

In this regard, she noted, “Although previous associations between exposure to gaseous pollutants and hypertension have shown some discrepancies, most studies reporting long-term exposure to particulate matter and incident high blood pressure have reported positive associations consistent with our findings.”

As Sergio Valdés explained, “our results support the need to improve air quality to the extent possible in order to reduce the risk of high blood pressure among our population, as even moderate levels such as those we report here increase the risk significantly.”

Hypertension Doubles Epilepsy Risk

A new study has found that hypertension may double an adult’s risk of developing epilepsy, according to a new study published in Epilepsia.

The study recruited 2986 US participants with an average age of 58 years, 55 new cases of epilepsy were identified during an average follow-up of 19 years. Hypertension, defined as presence of elevated blood pressure or use of antihypertensive medications, was linked to a nearly 2-fold higher risk of epilepsy. After excluding participants with normal blood pressure who were taking antihypertensive medications, hypertension was linked to a 2.44-times higher risk of epilepsy.

“Our study shows that hypertension, a common, modifiable, vascular risk factor, is an independent predictor of epilepsy in older age,” said co–lead author Maria Stefanidou, MD, MSc, of Boston University School of Medicine. “Even though epidemiological studies can only show association and not causation, this observation may help identify subgroups of patients who will benefit from targeted, aggressive hypertension management and encourage performance of dedicated clinical studies that will focus on early interventions to reduce the burden of epilepsy in older age.”

Firefighters’ Blood Pressure Soars in an Emergency

When the emergency alarm sounds, blood pressure (BP) among firefighters often soars, according to preliminary research presented at the American Heart Association’s Scientific Sessions 2021.

“All emergency and first responders should be aware of their health. They should know what their typical blood pressure level is and be aware of how it fluctuates. Most important, if they have high blood pressure, they should make sure it is well-controlled,” said senio author Deborah Feairheller, PhD.

The study recruited 37 male and 4 female volunteer and municipal firefighters who wore ambulatory BP monitors during an on-call work shift lasting at least 12 consecutive hours. In addition to the automatic BP readings from the monitor, study participants were instructed to prompt the monitor to take a BP reading whenever a pager or emergency call sounded and whenever they felt they entered a stressful situation. Participants also logged activities and call types for each measurement. The firefighters’ average age was 41.2 years. Average body mass index (BMI) of all participants was 30.3, with BMI ≥ 25 defined as overweight, while BMI ≥ 30 is defined as obesity. The firefighters all had high blood pressure, defined as systolic BP as 130 mm Hg or higher, or a diastolic BP of 80 mm Hg or higher, as defined by the American Heart Association’s most recent guideline.

The findings were that:

  • Average BP and heart rate (HR) were 131/79.3 mmHg and 75.7 beats per minute (bpm) respectively.
  • Compared with the reading immediately preceding the call, systolic BPsurged an average of 19.2 mm Hg with fire calls and 18.7 mm Hg with medical calls.
  • Meanwhile, diastolic BP surged 10.5 mm Hg with fire calls and 16.5 mm Hg with medical calls.
  • Compared with the average BP during the entire 12-hour shift, systolic BP was 9% higher during fire calls, and diastolic BP was 9% higher during medical calls.
  • Average HR also increased during both types of calls: 10bpm with fire calls, and 15bpm for medical calls.
  • There were no significant differences in BP, HR or BP surge levels when comparing responses among fire calls, medical calls, riding an emergency vehicle or false alarms.

Surprising findings
“The public knows the value that emergency responders provide to communities. We hope to increase awareness that many firefighters have hypertension and that their blood pressure can increase to very dangerous levels when responding to emergency calls,” said Dr Feairheller.

“The current data show that almost 75% of firefighters have hypertension, and less than 25% have their blood pressure under control. I hope that our research can help identify occupational factors that affect blood pressure and increase awareness among this population,” Dr Feairheller added.

They were also surprised at the findings on diastolic BP increases. “We anticipated systolic blood pressure surges because that reading is usually more responsive to stimuli; however, the extent of the diastolic blood pressure surge was unexpected,” said Dr Feairheller.

The investigators are currently exploring whether diet and exercise regimens could help to lower the BP surge that firefighters experience during emergency calls.

An Extra Drug or More of the Same for Uncontrolled Hypertension?

A new study may help people with uncontrolled hypertension and their doctors decide whether to increase the dose of one of their existing drugs, or add a new one, to bring down their blood pressure.

Reviewing data from veterans over age 65 receiving treatment over two years, researchers found that patients have a better chance of adhering to their medication regimen if their doctor maximises the dosage of one of the drugs they’re already taking. While both strategies decrease blood pressure, they found adding a new medication has a very slim advantage over increasing the dose of an existing medication, despite some of the patients being unable to stay on the new medication.

In the end, the researchers say, the new findings could add to discussions between physicians and patients whose blood pressure remains elevated despite starting medication treatment.

The findings, reported in the Annals of Internal Medicine, focus on patients whose initial systolic blood pressure was above 130mmHg.

By looking back at VA and Medicare data, the researchers were able to see patterns in treatment and blood pressure readings over time, in a kind of natural experiment. All the patients were taking at least one blood pressure medication at less than the maximum dose and had a treatment intensification at the start of the study period, indicating that their physicians thought they needed more intense treatment.

Intensifying treatment must be carefully considered, as there are many concerns — whether a drug interaction if a new drug is added, or an electrolyte imbalance with high doses, or fainting and falling if a person’s pressure gets too low .

This is the first time the two approaches have been compared, said first author Dr Carole E. Aubert.

“There’s increasing guidance on approaches to starting treatment in older adults, but less on to the next steps to intensify treatment, especially in an older and medically complex population that isn’t usually included in clinical trials of blood pressure medication,” she said. “How can we increase medications safely in a population already taking many medications for hypertension and other conditions.”

“Treatment guidelines do suggest starting treatment with multiple medications, and clinicians are comfortable with an approach of ‘starting low and going slow’ in older patients,” said senior author Dr Lillian Min. “But these results show that in older patients, we have further opportunity to tailor choices in intensifying drug therapy for hypertension, depending on the individual patient’s characteristics.”

She continued, “Is the patient more likely to stick to a simpler regimen? Then increase an existing medication. Or is the blood pressure very high and the clinician is more concerned about reducing it? Then consider starting a new medication now.”

For older adults already on various medications, overcomplicating it with another pill may be excessive. The risks of polypharmacy are already well known, Dr Min said.

Home BP Monitoring Gets the Thumbs-up From Patients

Adults needing to track their blood pressure regularly for a hypertension diagnosis preferred home monitoring blood pressure versus at a clinic, kiosk or with a 24-hour wearable device, according to preliminary research presented at the American Heart Association’s Hypertension Scientific Sessions 2021.

According to the American Heart Association, about half of US adults have hypertension, and of those with high blood pressure (BP) over a third are unaware they have it. H

“Most hypertension is diagnosed and treated based on blood pressure measurements taken in a doctor’s office, even though the U.S. Preventive Services Task Force and the American Heart Association recommend that blood pressure measurements be taken outside of the clinical setting to confirm the diagnosis before starting treatment,” said lead study author Beverly Green, MD, MPH, senior investigator and family physician at Kaiser Permanente Washington Health Research Institute. “It is the standard that blood pressure monitoring should be done either using home blood pressure monitoring or 24-hour ambulatory blood pressure monitoring prior to diagnosing hypertension.”

The “gold standard” for out-of-office measurement to determine a diagnosis of high blood pressure is 24-hour ambulatory blood pressure monitoring devices, worn day and night to take continuous blood pressure readings. Measuring BP on a home device with a normal BP cuff, can be more convenient.

The researchers studied adherence and acceptability of different blood pressure measuring methods among 510 adults with elevated BP but without a hypertension diagnosis. Participants in the study were an average age of 59 years old; half were male; the average BP was 150/88 mm Hg and were taking blood pressure-lowering medications.

Participants were randomised to either clinic measurements, home monitoring or kiosk blood pressure monitoring.

Those in the group for clinic measurements were asked to return to the clinic for at least one additional blood pressure check, as is routine in diagnosing hypertension in clinical practice. The home group received home blood pressure machines and the training to use them, and were asked to measure their blood pressure twice in a row, two times daily, for five days, for a total of 20 measurements. The kiosk group was asked to take their blood pressure at a kiosk in their clinic or at a nearby pharmacy three times each on three separate days, for a total of nine measurements. All participants were asked to complete their group-assigned diagnostic regimens within three weeks, and then to complete 24-hour ambulatory blood pressure monitoring. Researchers compared adherence to and the acceptability among each diagnostic method.

They measured adherence to monitoring by noting the percent of individuals in each group who completed their assigned measurement method as instructed. They measured acceptability with questionnaires.

Researchers found that overall acceptability was highest for the at-home group, followed by the clinic and kiosk groups, while 24-hour ambulatory blood pressure monitoring was the least popular. Adherence to the monitoring regimen was lowest in the kiosk group, but more than 90% in the home testing group; more than 87% in the clinic group; nearly 68% in the kiosk group; and 91% for 24-hour ambulatory monitoring among all participants.

“Home blood pressure monitoring was the most preferred option because it was convenient, easy to do, did not disturb their daily personal or work routine as much, and was perceived as accurate,” said Dr Green. “Participants reported that ambulatory blood pressure monitoring disturbed daily and work activities, disrupted sleep and was uncomfortable.”

When asked which diagnostic testing regimen they would prefer, more than half chose home blood pressure monitoring, especially if they were assigned to the home group, where almost 80% preferred home monitoring.

Dr Green suggests that clinicians routinely offer home blood pressure monitoring to their patients with elevated blood pressure.
“Health care professionals should work toward relying less on in-clinic visits to diagnose hypertension and supporting their patients in taking their blood pressure measurements at home,” Dr Green said. “Home blood pressure monitoring is empowering and improves our ability to identify and treat hypertension, and to prevent strokes, heart attacks, heart failure and cardiovascular death.”

Taking Action Before and Between Pregnancies Reduces Risk of Preeclampsia

In a new study, John Hopkins researchers have found that the periods before pregnancy and in between pregnancies are crucial times to address preeclampsia risk factors like obesity, diabetes and hypertension.

Preeclampsia, a common pregnancy complication, is characterised by high blood pressure and signs of damage to the liver, kidneys or other organs. It usually starts after 20 weeks of pregnancy in women whose blood pressure had previously been normal. .

The team, led by S. Michelle Ogunwole, MD, a fellow in the Division of General Internal Medicine, and Wendy Bennett, MD, MPH, associate professor of medicine, both at the Johns Hopkins University School of Medicine, published their findings in the Journal of the American Heart Association.

Dr Ogunwole said: “Preconception health care is really important as it’s a window of opportunity to think about your future health. We encourage patients to work on chronic disease issues before their pregnancies and between their pregnancies.”

A woman who develops preeclampsia during her first pregnancy has a higher risk of the condition recurring in a second or any successive pregnancies, she said.

“As an internist concerned about maternal outcomes, I am interested in what health care providers can do to help women reduce their risk of preeclampsia, including being a big proponent of preconception counseling,” said Dr Ogunwole.

The team compared two sets of women who were participating in the Boston Birth Cohort. Since 1998, the cohort has looked at a broad array of early life factors and their effects on pregnancy, infancy and child health outcomes. The researchers wanted to understand the differences between women who developed preeclampsia and those who did not, and how a first case of the condition affects subsequent pregnancies. Dr Ogunwole’s team studied 618 women to gain “rich maternal health data among racially and ethnically diverse pregnant women.”

“We wanted to make sure that we’re asking questions in a population that looks like the populations we serve,” she says. “I’m interested in the life course of women and pregnancy complications that can shape the trajectory of their future health.”

The researchers found that obesity, diabetes, high blood pressure, gestational diabetes and preterm birth were common factors in women who had preeclampsia during both first and second pregnancies, or who developed the condition during gestation with a second or later child.

“We know that improving weight will improve other conditions, so we advise that women create healthier lifestyles before and between pregnancies,” said Dr Ogunwole. “Whether you have another pregnancy again or not, you can still improve your overall health.”

Future research should hopefully include larger trials to confirm their results. Dr  Ogunwole  also plans to study the structural barriers that may prevent women from engaging in healthy lifestyles and develop strategies to improve long-term health outcomes for women.

Gut Microbiome Moderates BP Benefits of Flavonoids

Flavonoid-rich foods, such as berries, apples, pears and wine, seem to reduce hypertension due in part to characteristics of the gut microbiome, according to a new study published in Hypertension.

“Our gut microbiome plays a key role in metabolising flavonoids to enhance their cardioprotective effects, and this study provides evidence to suggest these blood pressure-lowering effects are achievable with simple changes to the daily diet,” said lead researcher Aedín Cassidy, PhD, chair and professor in nutrition and preventive medicine at the Institute for Global Food Security at Queen’s University.

Flavonoids are compounds found naturally in fruits, vegetables and plant-based foods such as tea, chocolate and wine. They have miscellaneous favourable biochemical and antioxidant effects associated with various diseases such as cancer, Alzheimer’s disease, atherosclerosis, etc. Flavonoids are broken down by the body’s gut microbiome. Recent studies found a link between gut microbiota, the microorganisms in the human digestive tract, and cardiovascular disease (CVD). Gut microbiota are highly individual, and seem to be associated with CVD.

With studies suggesting flavonoids may reduce heart disease risk, the researchers investigaged the role of the gut microbiome in this. 
Researchers drew on a group of 904 adults between the ages of 25 and 82, 57% men from Germany’s PopGen biobank. Researchers evaluated the participants’ food intake, gut microbiome and blood pressure levels together with other clinical and molecular phenotyping at regular follow-up examinations.

Participants’ intake of flavonoid-rich foods during the previous year was calculated from a self-reported food questionnaire detailing the frequency and quantity eaten of 112 foods.

Participants’ gut microbiomes were assessed by faecal bacterial DNA in stool samples. After an overnight fast, participants’ blood pressure levels were measured. Researchers also collected participants’ lifestyle information, and measured BMI and other physical characteristics,

The analysis found that:

  • Study participants with the highest intake of flavonoid-rich foods, including berries, red wine, apples and pears, had lower systolic blood pressure levels, as well as greater gut microbiome diversity than the participants with the lowest levels of flavonoid-rich food intake.
  • Up to 15.2% of the association between flavonoid-rich foods and systolic blood pressure could be explained by the diversity found in participants’ gut microbiome.
  • Eating 1.6 servings of berries per day (one serving = 80 grams, or 1 cup) was associated with an average reduction in systolic blood pressure levels of 4.1 mm Hg. 12% of the association was explained by gut microbiome factors.
  • Drinking 2.8 glasses (125 ml of wine per glass) of red wine a week was associated with an average of 3.7 mm Hg lower systolic blood pressure level, of which 15% could be explained by the gut microbiome.

“Our findings indicate future trials should look at participants according to metabolic profile in order to more accurately study the roles of metabolism and the gut microbiome in regulating the effects of flavonoids on blood pressure,” said Cassidy. “A better understanding of the highly individual variability of flavonoid metabolism could very well explain why some people have greater cardiovascular protection benefits from flavonoid-rich foods than others.”

While this study suggests potential benefits to consuming red wine, the American Heart Association suggests that if you don’t drink alcohol already, you shouldn’t start.

Study limitations include not being able to account for all factors, such as genetics and lifestyle. The authors noted the focus of this study was on specific foods rich in flavonoids, not all food and beverages with flavonoids.

Parental History Not The Only Premature Heart Attack Risk

A new study has shown that, while parental history is a contributing factor, young heart attack victims are more likely to be smokers, obese, and have high blood pressure or diabetes compared to their peers.

“The findings underline the importance of preventing smoking and overweight in children and adolescents in order to reduce the likelihood of heart disease later in life,” said study author Professor Harm Wienbergen of the Bremen Institute for Heart and Circulation Research.

“Understanding the reasons for heart attacks in young adults is important from a societal perspective due to their employment and family responsibilities,” he continued. “However, there are limited data on the predictors of heart events in this group.”

The researchers compared the clinical characteristics of consecutive patients admitted to hospital with acute myocardial infarction at 45 years of age or younger against randomly selected individuals from the German population. Cases and controls were matched according to age and gender. The case-control study enrolled a total of 522 patients with 1191 matched controls from a national database.

The researchers found that the proportion of active smokers was more than three-fold higher in the young heart attack group compared to the general population (82.4% vs 24.1%). Patients were more likely to have high blood pressure (25.1% vs 0.5%), diabetes (11.7% vs 1.7%) and a parental history of premature heart attack (27.6% vs 8.1%) compared to their peers. Patients were more often obese, with a median body mass index (BMI) of 28.4 kg/m2 compared to 25.5 kg/m2 for controls. In contrast, the proportion consuming alcohol at least four times a week was higher in the general population (11.2%) compared to heart patients (7.1%).

The researchers analysed the independent risk factors for the occurrence of acute myocardial infarction at 45 years of age or younger. The analysis was adjusted for age, sex, high blood pressure, diabetes, active smoking, body mass index, alcohol consumption, years of school education, and birth in Germany.

Hypertension was associated with an 85-fold odds of a heart attack aged 45 or under. The corresponding odds of a premature heart attack associated with active smoking, diabetes mellitus, parental history and obesity (BMI 30 kg/m2 or above) were 12, 5, 3 and 2. Alcohol consumption was associated with a lower odds of heart attack at a young age with an odds ratio of 0.3.

Prof Wienbergen said: “Our study shows that smoking and metabolic factors, such as hypertension, diabetes and obesity, are strongly associated with an increased likelihood of premature acute myocardial infarction. A protective effect of moderate alcohol consumption has been described by other studies and is confirmed in the present analysis of young patients.”

He concluded: “Our study suggests that family history is not the only predisposing factor for early heart attacks. The findings add impetus to the argument that young people should be educated about why it is important to avoid smoking and have a healthy body weight.”

Nine in Ten Hypertension Cases Need More Treatment

A series of studies has shown that in most cases, hypertension is not being adequately treated.

Hypertension is the leading treatable cause of illness and death worldwide. More than a billion people are hypertensive, defined as having diastolic blood pressure (BP) with 140mmHg or higher, or diastolic blood pressure (DBP) 90 mmHg or higher. Fewer than half of people with hypertension are aware of their condition.

This condition increases the risk of several dangerous illnesses, such as myocardial infarction (MI) and stroke, and of dying prematurely. For some patient categories, the most advantageous BP levels in terms of avoiding MI and stroke are uncertain.

In one of the studies in his thesis at Sahlgrenska Academy, University of Gothenburg, specialist doctor Johan-Emil Bager investigated the link between BP levels and the risk of MI or stroke in 5041 older patients.with hypertension but no history of heart attacks or strokes.
Risk for MI or stroke was found to be some 40 percent lower for the patients with systolic blood pressure (SBP) below 130 mmHg, compared with those in the SBP 130–139 range. In the latter group, 5.2 percent of the patients experienced a heart attack or stroke during the follow-up period, compared with 3.4 percent of those in the lower SBP group.

This pattern was repeated in another study, which investigated the risk of haemorrhagic stroke at different levels of BP in 3972 patients with atrial fibrillation (AF). These patients were receiving treatment with blood-thinning drugs, such as Warfarin or Eliquis.

The study showed that patients with SBP ranging from 140 to 179 mmHg had a haemorrhagic stroke risk roughly double that of patients with SBP of 130–139 mmHg. In the patient group with higher SBP, 1.4 percent suffered a hemorrhagic stroke during the follow-up period, compared with 0.7 percent of patients in the group with lower SBP.

A separate study with data on 259 753 patients also demonstrated insufficiency of hypertension treatment. Nine out of ten patients had either insufficient BP control or high blood lipids (cholesterol), or were smokers.

Johan-Emil Bager at the University of Gothenburg, said: “This means that an overwhelming majority of the patients with high blood pressure are exposed to at least one important, modifiable risk factor for cardiovascular disease and premature death.”

He concluded that an unnecessarily high number of people in Sweden suffer MI or stroke, or die prematurely, because of insufficiently treated hypertension.

“Health professionals and patients with hypertension alike need to aim higher when it comes to treating high blood pressure. The vast majority of patients with hypertension could reduce their MI and stroke risk by lowering their BP and blood lipids with more drugs, or through lifestyle changes.”
