Chemical pollutants such as lead, perfluoroalkyl and polyfluoroalkyl substances (also known as PFAS), and pesticides may contribute to heart disease risk. Possible routes of exposure for all three include drinking water and food. Residue and dust from many common items (such as water-resistant clothing and personal care products) may expose people to PFAS. People can limit their exposure by testing and, if needed, filtering their drinking water; choosing PFAS-free products when possible; using non-chemical pest control methods; and choosing organic foods.

Advice about the amount of physical activity required to stave off heart disease and other chronic ailments is usually expressed as a time-based goal. But counting steps may be just as useful, according to a 2024 study.

Chest pain is an indicator of a possible heart attack, but it may also be a symptom of another condition or problem. The type and location of the pain can help doctors determine what is causing it.

Older adults might be able to lower their blood pressure by reducing their sitting time by as little as 30 minutes per day, according to a 2024 study.

The spouses of people who have heart attacks, strokes, and heart failure may face an elevated risk of depression, according to a 2024 study.

Physical activity lowers cardiovascular disease risk in part by reducing stress-related activity in the brain, according to a 2024 study.

People who have or are at risk for cardiovascular disease should be extra cautious when exercising outside when it's hot, humid, and hazy, as they are more vulnerable to the hazards of high temperature and air pollution. To exercise safely during a heat wave, people should avoid being outside during the middle of the day; wear light-colored, lightweight clothing; and be careful to stay hydrated.

The American Heart Association's first-ever scientific statement on artificial intelligence (A.I.) in cardiology explores how the technology may improve how doctors prevent, detect, and treat heart disease. For example, A.I. data from patch monitors may predict who will develop potentially serious heart rhythms. Applying A.I. tools to a single chest x-ray may predict a person's risk of heart attack and other serious health problems.

A 2024 study suggests using cannabis weekly may be associated with an increase in people's risks of heart attack and stroke, and the risks rise dramatically with more frequent use.

A large observational study published in 2024 suggests that stroke isn't the biggest risk of atrial fibrillation (an abnormal heart rhythm condition). The biggest risk seems to be heart failure, a condition in which the heart is unable to pump blood effectively.
