A one-time infusion of a gene-editing therapy called CTX310 may safely lower cholesterol and triglyceride levels, according to a small preliminary trial. The first-in-human study, published in 2025, included 15 people with uncontrolled LDL cholesterol, triglycerides, or both.

Long QT syndrome is a disorder of the heart’s electrical system that can be either acquired (for example, due to a medication) or congenital. Although usually people have no symptoms, it can cause a fast, erratic heartbeat that may lead to shortness of breath, fainting, and sometimes death.

For stroke survivors, reaching a very low LDL (bad) cholesterol level may reduce their risk of future strokes and other cardiovascular problems, according to a 2025 study.

Taking magnesium supplements has become popular in recent years, and some evidence suggests this practice may help lower blood pressure, especially for those with high blood pressure or low magnesium levels. But a healthy diet is a better way for people to ensure they're getting enough of this essential nutrient.

Up to half of all heart attack survivors experience some type of psychological distress, including sadness, worry, or irritability. This problem is known as post-myocardial infarction psychological distress. Cardiac rehabilitation is the best way to get treatment.

Chronic, low-level inflammation is just as important as cholesterol in causing clogged heart arteries. Cardiologists are calling for more widespread testing for inflammation, which is easily measured with an inexpensive blood test.

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.

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.

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.
