Beta blockers have long been standard treatment for people after a heart attack. New evidence suggests they may not help those whose hearts still pump normally, though the drugs remain important for heart attack survivors with reduced ejection fraction.

A transient ischemic attack (TIA), or ministroke, is a serious warning sign for future stroke, especially in the first 48 hours. Medications plus lifestyle changes-healthy eating, regular exercise, and blood pressure control-can significantly lower that risk.

Heart palpitations are sensations of a pounding or racing heartbeat, often triggered by stress, stimulants, or hormonal changes. They're usually harmless but should be checked by a doctor. Palpitations may improve with lifestyle changes or treatment for underlying conditions.

A pescatarian diet pairs plant-based eating with fish and shellfish, offering key nutrients and heart- and brain-protective omega-3s. Choosing smaller, sustainably caught seafood helps limit environmental impact and mercury exposure.

A 2025 study found that increased physical activity and adherence to a Mediterranean diet each promoted a healthy weight and less build-up of harmful (visceral) body fat. Combining exercise plus a high-quality diet had the greatest benefit.

A 2025 scientific statement from the American Heart Association indicated that women with cardiovascular disease are far less likely than men with the condition to take part in cardiac rehabilitation programs, despite the proven benefits.

A 2025 study suggested that women are less likely to develop coronary artery disease even when engaging in less moderate-to-vigorous exercise than men.

Higher exposure to light at night between 12:30 a.m. and 6 a.m. is linked to an increased risk of cardiovascular problems including coronary artery disease, stroke, atrial fibrillation, heart attack, and heart failure.

Reclining and lying down may be linked to worse cardiovascular health while short bouts of sitting or standing may reduce cardiovascular risk, according to a 2025 study.

A 2025 analysis suggests that far fewer people are considered candidates for low-dose aspirin to prevent heart disease with the updated PREVENT risk calculator compared with the older risk calculator.
