The 2025 cardiopulmonary resuscitation (CPR) guidelines from the American Heart Association provide recommendations for recognizing and responding to several different types of emergencies, including choking, a suspected opioid overdose, and cardiac arrest.

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.

High-intensity interval training alternates short bursts of hard effort with recovery, boosting aerobic fitness, heart health, and muscle in less time. For older adults, adjusting intensity to current fitness levels helps keep HIIT safe and effective.

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.

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.

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.

Social media posts tend to exaggerate side effects (such as muscle aches and memory problems) associated with statins and may spread invalid information about these drugs. This misinformation is a major threat to public health, according to a 2025 article.

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.
