Obesity is a common, chronic disease that can harm the heart. The powerful weight-loss medications known as GLP-1s, semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound), are now recommended as first-line therapy for eligible people, according to the American College of Cardiology. People using these drugs should work with a dietitian or nutritionist who can help them create a personalized eating plan that ensures they're getting enough nutrients while minimizing common side effects.

Everyone should learn what to do if a heart attack or stroke occurs, beyond calling 911. It helps to become familiar with heart attack and stroke symptoms, so they can be recognized. It's also important to speak with one's own doctor in advance, to find out if he or she advises taking an aspirin in one of those emergencies. Other precautions include keeping emergency contact and medication lists updated and handy, and talking about emergency plans with family and friends, especially one's health care proxy.

A 2025 study found that people who had received a shingles vaccination had lower risks for stroke and various types of heart disease, including heart failure and heart attacks, compared with people who didn't receive a shingles vaccine.

Many devices that measure blood pressure without an inflatable arm cuff are in development, including a wristband recently cleared by the FDA for over-the-counter sale. It relies on a light-based sensor to detect changes in the amount of blood flowing through the vessels of the inner wrist, a technique known as photoplethysmography. But the devices have to be periodically calibrated, and as yet, there are no standards to validate the accuracy of cuffless devices.

Coronary artery disease, the most common form of heart disease, occurs when cholesterol-laden debris narrows the arteries that supply blood to the heart. It is treated with lifestyle changes and medications. However, sometimes people also need a procedure called angioplasty to open a blocked or narrowed artery to improve blood flow to the heart, along with insertion of a stent to hold it open. Most people need this if they experience a heart attack or unstable angina, when chest discomfort occurs repeatedly and unexpectedly, often at rest.

People with high blood pressure typically die earlier than people without the condition. A 2025 study suggests that they can significantly lower-or even eliminate-that difference by controlling several key risk factors.

Habits that promote cardiovascular health are linked to benefits in nearly every organ system and improved function throughout the body, according to a 2025 review of 483 studies.

People commonly experience heart palpitations, which feel like the heart flutters or skips a beat, or beats at a faster rate or in an irregular rhythm. They often last only seconds and can be unsettling. For the most part, palpitations are nothing to worry about. Still, these unusual heart sensations may indicate something more serious, such as atrial fibrillation, supraventricular tachycardia, or ventricular tachycardia. Palpitations that persist or cause other symptoms (such as lightheadedness) should be evaluated by a doctor.

Few people get the recommended two fruits and three vegetables per day. Tips for helping people add more produce into their diets include starting small (making just one minor addition or substitution at a time and sticking with it for several weeks); choosing smarter snacks (like hummus and carrots or apples and peanut butter); sneaking pureed vegetables into pasta and other dishes; making smoothies and soups; and relying on frozen fruits and vegetables.

For people with diabetes, a modified version of the Dietary Approaches to Stop Hypertension (DASH) diet can lower their blood pressure. Called DASH4D, it has fewer carbohydrates, more unsaturated fat, and slightly reduced amounts of potassium.
