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.

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.

For improving cardiovascular risk, a workout that combines heart-pumping aerobic exercise and strength-based moves may be just as effective as an all-aerobic regimen, according to a 2024 study.

People who lose weight with a portion-controlled diet and exercise may be able to reverse their diabetes. When that happens, their risk of heart disease and kidney disease declines, 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.

A 2024 study suggests doing a workout that's a combination of aerobics and strength training might reduce cardiovascular risk factors just as effectively as a workout that consists of aerobics only.

Whole or minimally processed foods tend to be best for heart health. But many processed foods-and even some that are ultra-processed-are also good options, provided people choose wisely. In three large studies, ultra-processed whole-grain bread, breakfast cereals, and yogurt were linked to a lower risk of type 2 diabetes and cardiovascular disease. Artificially and sugar-sweetened beverages, processed meats, and ready-to-eat dishes were linked to higher risks of those conditions.

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 calcium score is a good indicator of how much plaque is inside the heart's arteries. Treatments can replace cholesterol in plaque with scar tissue, which contains calcium and produces a higher calcium score, but this stabilized plaque lowers heart attack risk.
