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.

Pulse oximeter bias undercounts sleep apnea severity in Black patients

Sleep studies often use a pulse oximeter to determine the severity of sleep apnea. But a new study by investigators from Mass General Brigham reports that pulse oximeters may undercount breathing events in Black patients, potentially leading to inaccurate severity classifications.

Multi-component nutritional supplement improves markers of vascular health

A multi-component nutritional supplement has been found to improve markers of vascular health, in a randomized controlled trial led by the University of Surrey.

Switching to potassium-enriched salt could prevent millions of global deaths

Researchers from The George Institute for Global Health assessed the health benefits of switching the salt supply to potassium-enriched salt across 193 countries.

Good sleep protects brain health in people with cardiometabolic disease

People with type 2 diabetes, heart disease or stroke who sleep well have better cognitive function and greater brain volume than people with the same conditions who sleep poorly, according to a new study from Karolinska Institutet.

A three-drug diabetes pill outperformed dual therapy

Clinical trial results indicate that a fixed-dose combination of dapagliflozin, glimepiride, and metformin offers superior glycemic control in diabetes therapy.

TAVR procedures increase ninefold among patients younger than 70

New research simultaneously published today in JSCAI and presented at TCT 2026 found that the annual number of transcatheter aortic valve replacement (TAVR) procedures among patients younger than 70 increased nearly ninefold within one health system, rising from 15 in 2014 to 134 in 2024.

A low-calorie diet and exercise helped 54% of younger adults achieve diabetes remission

In a randomized clinical trial involving 96 adults with early-onset type 2 diabetes and obesity, a 24-week program combining a low-energy diet with supervised exercise achieved diabetes remission in 54% of participants, compared with 4% receiving usual care. The intervention also reduced body fat, largely preserved muscle mass, and improved strength and body-mass-adjusted fitness, although the additional benefits attributable specifically to exercise remain uncertain.

Heart disease and depression may affect brain aging in an unexpected way

A longitudinal study of 5,423 adults in England found that cardiovascular disease was associated with faster cognitive decline, with the strongest association observed among participants with consistently low depressive symptoms. Those with persistent moderate or high depressive symptoms generally experienced poorer cognitive performance and faster overall deterioration, despite showing a weaker additional association between cardiovascular disease and cognitive decline.

Scientists use extracellular vesicles to track source of chronic inflammation

A new technique to diagnose chronic inflammation developed at Nagoya University can read information from the surface and within individual extracellular vesicles in blood and urine.

FSU neuroscientist wins grant to study temperature's impact on salt taste

A Florida State University neuroscientist has received a new grant from the National Institutes of Health to investigate how a food or drink's temperature affects the way our brains process the taste of salt, a neural mechanism that plays a significant role in shaping eating behaviors and nutrition habits.

AI-powered heart MRI measurements better predict patients' survival

Artificial intelligence (AI) measurements of heart function from MRI scans are more strongly linked to how long patients live after their scan than measurements made by clinicians, suggesting that AI could provide a useful first-line approach to measuring heart function.

Global pediatric stroke burden remains high despite declining mortality

Pediatric stroke has been less recognized than adult stroke, and its risk factors, epidemiology and outcomes remain insufficiently understood.

Wearable devices and AI provide early warning signs of hypertensive crises

Using artificial intelligence (AI) to analyze patterns in measures from a portable cuff-based blood pressure monitor and health data from a wrist-worn device may help identify when adults with stage 2 high blood pressure (blood pressure ≥140/90 mm Hg) are at increased risk of a dangerously high blood pressure episode (>180/120 mm Hg with acute end-organ damage), known as a hypertensive crisis, up to three days before it occurs, according to new, independent, preliminary research to be presented at the American Heart Association's Scientific Sessions 2026.

Long-term study supports cardiovascular safety of contemporary hormone replacement therapy

Contemporary hormone replacement therapy (HRT) was not associated with an increased risk for heart attack, stroke, blood clots or death among women ages 45 to 59, according to a large, long-term study of over 52,000 women in Israel.

Two healthy diets stood out in a study of more than 7,000 adults

In a cross-sectional analysis of 7,256 adults from the Maastricht Study, researchers found that greater adherence to the DASH and Dutch Healthy Diet patterns was associated with higher very-low-frequency (VLF) heart rate variability power, particularly among participants not taking beta-blockers. No significant associations were observed across time-domain HRV measures after full adjustment, and the findings do not establish that these diets improve cardiovascular function.

New study links cannabis use to increased cardiovascular risk

Cannabis use, including marijuana, appears to be linked with increased cardiovascular risk, especially for stroke, making it an important consideration for heart disease and stroke prevention and counseling, according to independent, new preliminary research to be presented at the American Heart Association's Scientific Sessions 2026.

Extreme heat spikes hospital intensive care cardiac arrest admissions

As daily temperatures climbed above 90 degrees Fahrenheit (F) across the U.S., so did the rate of out-of-hospital (OHCA) cardiac arrest admissions to hospitals intensive care units (ICUs); however, the heat didn't appear to impact the overall outcomes of people admitted for cardiac arrest during heat waves compared to other times, according to new, independent, preliminary research to be presented at the American Heart Association's Resuscitation Science Symposium 2026.
