Resistance training (also called strength training or weight training) can improve heart-related risk factors such as blood pressure, blood sugar, blood lipids, and body composition. It's especially beneficial for older adults and people with an elevated risk for heart problems. A 2024 scientific statement from the American Heart Association recommends focusing on eight to 10 different exercises that target all the body's major muscle groups. Examples include chest presses, biceps curls, squats, and abdominal crunches.

A second opinion from a cardiologist may be helpful for people considering whether to undergo a specialized heart procedure. Such consultations may be increasingly appropriate as new, minimally invasive treatments for various heart problems become more widely available and more specialized. Others who might seek a second opinion include people with heart-related symptoms that persist despite treatment, who have been told they have no more options.

Every year, an estimated 600,000 people in the United States develop a blood clot deep inside the leg, known as deep-vein thrombosis. These clots usually develop in the lower leg, thigh, or pelvis but occasionally the arm. The affected area may be tender or painful, swollen, red or discolored, and warm to the touch. If a clot breaks free and travels to a lung, it can cause a pulmonary embolism. Symptoms of a pulmonary embolism include difficulty breathing that happens suddenly, a fast or irregular heartbeat, coughing up blood, and chest pain or discomfort, which usually worsens with a deep breath or coughing.

Telemedicine visits combined with self-measured blood pressure readings may help control high blood pressure better than traditional clinic visits, according to a 2024 study.

New guidelines for managing atrial fibrillation focus on lifestyle habits to prevent and control the disorder. One recommendation is for people to limit alcohol to one drink per day, or ideally less. Another is for people who are overweight or obese to lose weight, either by striving for a body mass index no greater than 27 or by shedding at least 10% of their body weight. The guidelines also suggest that people get three to four hours of exercise per week. And people with afib who snore should consider getting tested for sleep apnea.

Certain foods, such as beans, oats and whole grains, fatty fish, and fruits and vegetables that are high in fiber, can lower "bad" LDL cholesterol.

A 2023 study suggests replacing a daily serving of processed meats with whole grains, nuts, or beans is associated with lower odds of cardiovascular conditions such as heart attack or stroke.

Aortic stenosis occurs when the heart's aortic valve becomes stiff and calcified, narrowing its opening so blood cannot flow normally. This can cause symptoms such as shortness of breath, fatigue, lightheadedness, fainting, and chest tightness. Neither lifestyle nor medications can slow or reverse aortic stenosis. People born with a bicuspid aortic valve are at high risk, but most people with aortic stenosis have a normal appearing valve. The only treatment is to replace the damaged valve using open heart surgery or a less invasive, nonsurgical approach called transcatheter aortic valve implantation.

A 2023 study suggests that following a healthy vegan diet may improve cardiometabolic risk factors (such as LDL cholesterol and weight) more than eating even a healthy omnivorous diet.
