Heart Disease

What Causes High Blood Pressure?

Blood pressure is the term used to describe the pressure exerted on the arterial walls as blood flows through them. This pressure is at its highest when the heart contracts and pumps blood through the arteries and is called the systolic pressure.

Gestational diabetes history linked to earlier development of type 2 diabetes

New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) shows that, in women that develop type 2 diabetes (T2D), those who had gestational diabetes (GD) when pregnant are developing T2D on average almost 13 years earlier than those who did not.

Some fertility treatments may raise Kawasaki disease risk in children

A large-scale study in Japan, led by researchers from the University of Osaka and the Osaka Women's and Children's Hospital, has found that certain fertility treatments are associated with an increased risk of Kawasaki disease before age five, although the association differed by treatment type.

Same foods, different timing, very different glucose patterns

In a randomized crossover study of 22 healthy, normal-weight Chinese men, consuming canola oil alone or with spinach before a high-glycemic mashed-potato meal produced flatter post-meal glucose and insulin responses than spinach alone or no preload. The effects were associated with increased GLP-1 signaling and slower gastric emptying, with the findings indicating that the unsaturated oil was the primary driver of the metabolic response.

ACC Quality Summit 2026 to focus on cardiovascular patient care improvements

The American College of Cardiology (ACC) Quality Summit 2026 will take place on September 16-18 in Orlando, connecting the cardiovascular quality improvement community to share ideas, learn from real-world successes and drive measurable improvements in the quality, safety and value of patient care.

Too little or too much testosterone may matter for heart rhythm

A review of clinical trials, observational studies, genetic analyses, and mechanistic research suggests that atrial fibrillation risk may follow a U-shaped relationship with testosterone, increasing at both low and high levels. Evidence on testosterone replacement therapy remains mixed, with researchers calling for prospective studies to determine whether mid-physiological testosterone targets and treatment formulation influence AF risk.

AI learned from cardiologists’ notes, and needed far less labeled ECG data

By teaching an AI system to connect raw heart signals with the clinical insights contained in cardiologists’ reports, researchers tested whether routine ECGs could reveal more with far fewer labeled examples.

Menopause may start changing the gut years before periods stop

A longitudinal study of 964 women found that blood markers of gut epithelial barrier dysfunction and microbial product translocation began to rise around 2 to 2.5 years before the final menstrual period and remained elevated after menopause. The findings suggest that changes in gut barrier integrity may form part of the biological transition through menopause and could help explain links between menopause, inflammation, and later health outcomes.

Your weekend meal schedule may matter more than you think

In a prospective analysis of 104,806 adults from the NutriNet-Santé cohort, greater differences in meal timing between weekdays and weekends were associated with higher risks of cardiovascular disease and coronary heart disease in men over a median 8.1 years. The associations were strongest when weekend eating shifted earlier, while delayed weekend eating was linked specifically to coronary heart disease, with no association detected for cerebrovascular disease.

Blocking a naturally occurring molecule reverses deadly lung disease in preclinical models

Researchers blocked a naturally occurring molecule to reverse pulmonary arterial hypertension in preclinical models, a finding that could point to a new treatment approach for people with a rare and often fatal lung disease.

Post-trauma mental health conditions increase future cardiovascular risks

Mental health conditions, such as posttraumatic stress disorder (PTSD), substance abuse, depression and anxiety, can develop after people experience trauma.

Scientists develop lab-grown heart tissue model for heart failure

Scientists study the underlying causes of a disease or test new potential drugs in animal models or cells obtained from human biopsy specimens before clinical trials.

Plant-based fats improve long-term survival for prostate cancer patients

Men diagnosed with nonmetastatic prostate cancer can generally expect to live for many years after their diagnosis. However, cardiovascular disease and other cancers remain important threats to their long-term health.

Muscle matters: Simple scan could predict heart surgery risks

Around one in four heart surgery patients develop serious lung complications – but a new Adelaide-led study is testing a simple bedside scan that could predict who is most at risk before symptoms appear.

Alcohol-related liver cancer deaths were falling. Then the trend reversed during the COVID-19 pandemic

A global analysis of GBD 2023 data found that alcohol-attributable liver cancer mortality increased modestly from 1990 to 2023, while mortality from alcohol-attributable cirrhosis, alcoholic cardiomyopathy, and alcohol use disorders declined. Liver cancer mortality shifted from a pre-pandemic decline to an increase during 2020–2023, particularly among women, although the researchers cautioned that the ecological analysis cannot establish that pandemic-related changes caused the reversal.

ECG-CLIP improves heart disease detection using less labeled data

Clinicians often use a medical test called a 12-lead electrocardiogram (ECG) to diagnose heart problems, which uses electrodes placed on the chest and limbs to record the heart's electrical activity.

University of Missouri researchers are advancing a promising new approach to treating a serious heart condition that affects millions of older adults worldwide.

Smartwatches may overestimate calories burned during exercise

Smartwatches can significantly overestimate how many calories people burn during exercise, and their calorie estimates become less accurate as body fat increases, according to a new Florida International University study.

Flavorings, colors and sweeteners emerge as UPF markers linked to depression risk

A prospective UK Biobank study of 171,818 adults found that greater estimated exposure to foods containing flavorings, coloring agents, and sweeteners was dose-dependently associated with a higher risk of incident depression over 10.7 years. The findings suggest that specific markers, rather than ultra-processed foods uniformly, may help explain associations between UPF consumption and depression risk.

Blocking a key protein protects against metabolic liver damage

Obesity-related metabolic liver disease affects hundreds of millions of people worldwide, but only some fraction of those livers develop scarring, become inflamed, and eventually fail. University of Utah researchers have identified a protein, EFHD1, that appears to drive that transition by triggering an out-of-place antiviral immune response.

Coronary angiography can be safely delayed after out-of-hospital cardiac arrest without ST elevation

Immediate coronary angiography did not improve 30-day survival compared with a deferred strategy in patients without an ECG ST-elevation after out-of-hospital cardiac arrest.
