Cardiovascular Disease

Cardiovascular disease involves the heart and vessels and is the number one killer in the U.S. accounting for nearly 30-percent of all deaths. Cardiovascular disease has a number of forms but the most common are myocardial infarction and angina pectoris which affect the heart itself.

What is Cardiovascular Disease?

Diseases of disorders of this system are termed cardiovascular diseases. Cardiovascular diseases kill an estimated 17 million people worldwide each year. Majority of these are due to heart attacks and strokes.

Abortion restrictions linked to higher maternal death rates

The increased number of state-level abortion restrictions in the U.S. was associated with a parallel increase in maternal deaths between 2005 and 2023, according to new research presented today at the Society for Maternal-Fetal Medicine (SMFM) 2026 Pregnancy Meeting.

Public preparedness key to improving cardiac arrest survival

When a medical emergency happens, time matters and a quick response is needed. During American Heart Month 2026, the National Fraternal Order of Police joins the American Heart Association in urging Americans everywhere to be the help until help arrives and learn how to respond in a medical emergency such as cardiac arrest – when providing help like cardiopulmonary resuscitation (CPR) can be the difference between life and death.

Early heart disease risk factors identified in South Asian adults in the U.S.

South Asian adults in the U. S. were more likely to have risk factors for atherosclerotic cardiovascular disease (ASCVD) by age 45 when compared to white, Black, Chinese or Hispanic adults in the same age group, according to a study published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Healthy low-carbohydrate and low-fat diets may improve cardiovascular health

The quality of a low-carbohydrate or low-fat diet may matter more than the amount of carbohydrates or fat consumed when it comes to reducing heart disease risk, according to a new study published in JACC, the flagship journal of the American College of Cardiology.

Night-time traffic noise may affect metabolic health

A new study has found that nighttime noise exposure is associated with changes in blood cholesterol and lipid-related metabolites in adults, which are known risk factors for cardiometabolic diseases.

Semaglutide lowers cardiovascular events even without major weight loss, researchers report

Semaglutide reduced major adverse cardiovascular events in adults with overweight or obesity and established cardiovascular disease regardless of baseline adiposity. Cardiovascular benefit was largely independent of overall weight loss, with waist circumference reduction explaining only part of the effect.

Review links betel nut addiction to cancer, heart disease, and metabolic risks

This review examines the epidemiology, health risks, neurobiological mechanisms, and emerging treatments related to betel nut addiction worldwide. It highlights strong links with oral cancer, cardiometabolic disease, and addiction pathways while noting limited established therapies and the need for coordinated public health strategies.

Eating fewer foods of concern may protect the heart beyond pills

A prospective cohort study in adults with hypertension and or hypercholesterolemia found that lower intake of ultra processed foods or foods flagged by front of pack nutrition warnings was associated with reduced cardiovascular disease risk. These associations persisted regardless of cardioprotective medication use, suggesting dietary quality contributes independently to cardiovascular prevention.

Early bone molecular changes signal osteoarthritis progression

Osteoarthritis often goes undetected until cartilage damage is advanced, limiting treatment options. A new study shows that molecular changes in subchondral bone occur earlier and can signal disease progression before cartilage loss.

Influenza viruses can directly impair heart function

Mount Sinai researchers have identified a cellular mechanism linking infections from influenza A viruses (IAVs) to cardiovascular disease, providing critical insights on how influenza can damage the heart and increase the risk of a heart attack or other major cardiovascular event.

Study reveals DNA methylation score that better detects alcohol intake than standard biomarkers

A Mediterranean cohort study evaluated a DNA methylation biomarker of alcohol intake and compared it with conventional indicators such as GGT. The epigenomic score correlated with alcohol exposure, linked to telomere shortening and epigenetic aging markers, but findings remain observational and population-specific.

New analysis asks if alcohol guidance needs stronger trials to settle the health debate

The viewpoint reviews conflicting evidence on alcohol consumption, highlighting discrepancies between observational studies, genetic analyses, and public health guidance. It concludes that large randomized trials comparing alcohol moderation versus cessation are needed to clarify long-term health effects.

AI stethoscope doubles detection of serious valve disease in primary care study

A prospective primary care study found that an AI-enabled digital stethoscope substantially improved sensitivity for detecting clinically significant valvular heart disease compared with standard auscultation. The technology identified more previously undiagnosed moderate-to-severe disease but showed reduced specificity, highlighting a trade-off between earlier detection and potential false positives.
