An inexpensive blood test that checks for a genetic variant of Lp(a)-a fatty particle similar to LDL cholesterol-may help clarify who might benefit from a daily low-dose aspirin, according to a 2025 review of study findings.

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.

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.

A heart disease diagnosis may trigger a bout of depression. But having depression can also leave people more vulnerable to heart disease. Some of the overlap stems from shared lifestyle factors, such as inactivity and an unhealthy diet. In addition to addressing those issues, other safe and effective ways to ease depression include working with a therapist, using a light box, and taking medications.

After common heart procedures or surgeries, medications to help prevent heart attacks and strokes are essential. These include a combination of drugs to prevent blood clots (which is known as dual antiplatelet therapy and usually taken for just one year); drugs to lower LDL cholesterol down to 70 milligrams per deciliter or lower; and drugs to keep blood pressure and blood sugar in a healthy range.

Getting vaccinated against influenza (flu), COVID-19, and pneumonia is especially important for people who have cardiovascular disease. The coughing and congestion that commonly occur with respiratory infections can make breathing more difficult, and the potential drop in oxygen puts added stress on the heart. Serious infections sometimes trigger sepsis, which happens when the immune system is overwhelmed or goes into overdrive, causing symptoms such as a rapid heart rate, very fast breathing, and low blood pressure. These complications can lead to a heart attack.

Meatless burgers-which include plant-based meat alternatives like Beyond Burger and Impossible Burger and veggie burgers-are healthy replacements for traditional hamburgers. Those with the lowest amounts of saturated fat and sodium are the best options.

Wearable fitness trackers like smart watches offer measurable and motivating data for exercise routines and safety, especially for people with heart conditions. Features include movement reminders, step counts (a daily total of 4,000 to 7,000 steps is considered beneficial), heart rate zones for exercise intensity, and measurements of heart rate recovery and variability to assess overall heart health. These tools can help optimize workouts and reveal potential issues.

Ultraprocessed packaged foods and drinks contain thickeners, preservatives, and other additives to improve their taste, texture, appearance, and shelf life. But the high amounts of salt, sugar, and fat in these products are probably more concerning for a person's health. Foods like sugary drinks and processed meats are the worst culprits. Eating a diet focused on whole, plant-based foods automatically lowers processed food intake and provides heart-protecting nutrients such as fiber, vitamins, and minerals.

A 2025 study finds that a first-time transient ischemic attack (TIA) can lead to the same long-term decline in thinking and memory problems as a full-blown stroke. Experts suggest cognitive testing after a TIA. People who have TIAs should take extra care to address risk factors for heart attack and stroke, such as high blood pressure and high cholesterol. Exercising regularly and staying socially active may help ward off cognitive decline.
