People with atrial fibrillation (afib) who drank an average of one cup of caffeinated coffee daily had a lower risk of recurrent afib compared to those who avoided caffeine, according to a 2025 study.

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.

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.

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.

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.

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.

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 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.
