Chemical pollutants: A growing concern for your heart

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.

Counting steps as good as time tracking for monitoring heart health

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.

Are heart attacks overdiagnosed?

Doctors may diagnose heart attacks in people who have not actually had one, in part because they screen people with subtle symptoms out of fear of missing the diagnosis. Failure to diagnose a heart attack is the No. 1 cause of malpractice payouts in the emergency department. But the blood test used to detect a heart attack is very sensitive, and other conditions such as myocarditis (heart inflammation) may be misdiagnosed as a heart attack. This problem of overdiagnosis can expose people to unneeded risks, high costs, and other downsides.

Chest pain: A heart attack or something else?

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.

Spouse's heart disease linked to higher risk of depression

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

Sitting less may help lower blood pressure

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.

Why do some heart drugs cost so much?

Health insurance companies sometimes require prior authorization for new, expensive medications. The high price patients pay for these drugs is related to complexities in health insurance coverage.

A personalized program to heal your heart

Cardiac rehabilitation, a personalized program of supervised exercise and heart-healthy lifestyle coaching, helps people recover from heart-related problems, including stable angina, heart attack, heart surgery, and stable heart failure. A 12-week program helps people regain their stamina, enabling them to resume their favorite activities, and may also lessen stress and depression. Cardiac rehab is also proven to lower the risk of future heart-related illness and hospitalization and may help people live longer.

Physical activity, the brain, and a possible link to better heart health

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

Can intermittent fasting improve heart health?

Intermittent fasting may help people lose weight and improve their cholesterol levels and other heart-related risks. One form of intermittent fasting is time-restricted eating, during which people eat only during a certain time window (usually eight hours) each day. Another approach, alternate-day fasting, involves fasting or significantly limiting calories for one or two days per week. But it's hard to maintain over the long run due to the challenges of following a strict eating schedule while juggling various work, family, and social commitments.
