New initiative aims to improve care for people living with Fontan circulation

The lifesaving surgery used to treat children with single ventricle heart disease, the Fontan procedure, can pose serious health complications throughout life.

Measuring heart fat with AI improves cardiovascular risk prediction

Mayo Clinic research identified a powerful new way to improve the prediction of a patient's long-term cardiovascular disease risk by enhancing a routinely performed imaging test with artificial intelligence (AI).

Irregular bedtime could double the risk of serious cardiac events

An irregular bedtime in midlife may signal an increased risk of cardiovascular disease. A new study from the University of Oulu suggests that large swings in when people go to bed could double the risk of serious cardiac events—particularly among those who get less than eight hours of sleep.

New clinical guideline adopts holistic approach to brain and heart health

A new brain–heart clinical practice guideline takes a holistic approach, integrating neurologic and mental health evidence with guidance for cardiovascular disease as many brain and heart conditions overlap and share similar risk factors.

Short bursts of vigorous activity can lower risk of major diseases

People who get just a few minutes of vigorous activity daily are less likely to develop eight major diseases, including arthritis, heart disease and dementia, according to research published in the European Heart Journal today (Monday).

Intensive LDL cholesterol-lowering shows major benefits for heart disease patients

Using cholesterol-lowering medications more intensively to achieve a more aggressive target for low-density lipoprotein cholesterol (LDL-C) reduced the rate of major cardiovascular events by one-third among patients with atherosclerotic cardiovascular disease (ASCVD), according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Home-delivered DASH diet improves blood pressure and cholesterol outcomes

Black adults with high blood pressure who received dietitian counseling and home deliveries of groceries aligned with the DASH diet—meaning high in fruits, vegetables, whole grains, low-fat dairy, nuts, seeds, legumes and lean proteins—had an average overall reduction in systolic blood pressure of 7 mm Hg at three months overall and a 5 mm Hg reduction compared with participants who received only basic dietary guidance and a grocery stipend, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Investigational drug lowers angiotensinogen but shows unclear blood pressure benefits

The investigational drug tonlamarsen—which is designed to lower blood pressure by reducing the production of angiotensinogen, a protein that turns into the hormone that regulates blood pressure—caused a significant and sustained drop in angiotensinogen but its impact on blood pressure was less clear, according to a study presented at the American College of Cardiology's Annual Scientific Session.

Intensive cholesterol‑lowering therapy reduces first major cardiac event in high‑risk patients with diabetes

Mass General Brigham researchers found that the intensive cholesterol‑lowering therapy evolocumab reduced the risk of a first major cardiovascular event in high‑risk patients who did not have known atherosclerosis (the build-up of plaque inside artery walls) but did have diabetes.

Left atrial appendage closure matches anticoagulants in AFib patients

For patients with non-valvular atrial fibrillation (AFib) who had no contraindications to taking oral anticoagulants, the use of a device to close off the left atrial appendage in the heart—a small pouch where blood can pool and form dangerous clots—was comparable to standard medication therapy in reducing the combined rate of all-cause stroke, cardiovascular death and systemic embolism at three years.

Heart structure changes in midlife linked to long-term disease risk

Higher left atrial end-systolic dimension (LASD), an increased measurement of the left upper chamber of the heart, and left ventricular mass (LVM), a clinical measurement of the weight of the heart's left ventricular myocardium, are well-established indicators of cardiovascular damage that are associated with a higher risk of cardiovascular disease (CVD) in the short-term (less than 10 years).

$Heart health linked to higher fracture risk in postmenopausal women$

Heart health linked to higher fracture risk in postmenopausal women

Postmenopausal women face a high risk of bone fractures. Due to declines in estrogen levels, which can lead to an increased risk of osteoporosis, even a low-impact fall can result in a serious hip, back or wrist injury.

Updated heart guidelines urge earlier screening for high blood cholesterol

For the first time since 2018, a clinical guideline from the American College of Cardiology and the American Heart Association for screening and managing blood cholesterol levels has been updated and jointly published in the Journal of the American College of Cardiology and Circulation.

New algorithm enables precise subtyping of metabolic liver disease

Metabolic-associated steatotic liver disease (MASLD) is a clinically heterogeneous condition with highly variable outcomes affecting more than 30% individuals globally.

Heart failure and atrial fibrillation share underlying genetic and molecular mechanisms

New research published in Nature Cardiovascular Research reveals that heart failure and atrial fibrillation share underlying genetic and molecular mechanisms, suggesting that the two cardiovascular conditions may be less distinct than previously thought.

American Heart Association funds student programs to expand CPR training

According to American Heart Association data, 9 out of every 10 people who experience cardiac arrest outside of a hospital die, in part because they do not receive immediate CPR more than half of the time.

Heavily processed foods may raise heart disease risk beyond poor nutrition alone

A 2026 review in Cardiology in Review reports that higher intake of ultra-processed foods is consistently associated with greater risks of cardiovascular disease, stroke, and cardiovascular mortality across cohort studies and meta-analyses. The paper also highlights plausible mechanisms involving gut dysbiosis, oxidative stress, and NF-κB-driven inflammation, with additives such as emulsifiers, preservatives, dyes, and sweeteners discussed as potential contributors.

Men show major gaps in male fertility knowledge, study finds

A study of 156 adult men found that knowledge about male fertility was generally low across both medical and lifestyle-related topics, with only 5 of 25 questions answered correctly by most respondents. Older men, those with a medical background, and those with suspected or treated infertility tended to score higher, while supplement use was common despite limited fertility literacy.

Healthy thymus gland linked to longer life and immune stability

The thymus is a small organ located in the upper chest that plays a central role in the immune system: it produces T cells - specialized immune cells that recognize and fight pathogens.

Mentally active sitting linked to reduced risk of dementia

New research distinguishing between passive and mentally active sitting in association with dementia has found that adults who engaged in extended durations of mentally passive sedentary behaviors had a higher risk of dementia.
