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.

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 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.

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.

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.

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.

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.

Performed during an echocardiogram, a bubble study involves injecting a small amount of fluid filled with tiny bubbles into an arm vein. It can reveal the path of blood flow through the heart and provide clues about the cause of an unexpected stroke.

Population-based studies have linked regular sauna use with better heart health. The high temperature inside a sauna-which usually ranges from about 150° F to 195° F-causes blood vessels to dilate, raising the heart rate and increasing blood flow throughout the body. However, randomized trials haven't found much evidence that saunas can improve measures of cardiovascular health. People with low blood pressure, valve disease, and heart failure should be cautious while using saunas.
