Indirect evidence suggests that for people with atrial fibrillation who always take apixaban (Eliquis) every 12 hours as prescribed, it may be slightly better than once daily rivaroxaban (Xarelto).

The weight-loss drug semaglutide is the first obesity treatment shown to help people live longer and have fewer cardiovascular problems. Developed as a drug for type 2 diabetes, semaglutide was first marketed as Ozempic; a higher-dose version for weight loss is called Wegovy. But because the drug is so popular, it can be hard to find, and it might not be covered by insurance.

A large waistline - 35 inches or more in women or 40 inches or more in men - can signal the presence of visceral fat. Located deep within the abdominal cavity, visceral fat pads the space around the organs and is closely linked to cardiovascular problems. Getting regular exercise (both aerobic and strength-based) and following a healthy, reduced-carbohydrate diet can help reduce visceral fat. Time-restricted eating may also help.

Blood thinners don't "thin" blood; rather, they discourage blood from clotting. Candidates for anti-clotting drugs are people at high risk for dangerous blood clots, such as those with atrial fibrillation or those who have received a stent. Others who can benefit from an anti-clotting drug are people who are immobile after surgery and individuals who have had deep-vein thrombosis (clots in the veins of the legs or arms) or pulmonary embolism (clots in the lungs). A higher risk of bleeding is the main side effect, but most people can tolerate the medication.

A nonsurgical approach for replacing a damaged aortic valve, known as transcatheter aortic valve replacement (TAVR), has become very popular in recent years. But it may not make sense for people in their 60s, who are likely to need a second valve replacement later in life. The valves used in TAVR only last about 10 years, on average. In addition, diagnosing and treating coronary artery disease may be more challenging in people who've had TAVR. Also, the surgery to replace a failed TAVR valve is more complicated than regular valve replacement surgery. So people who are likely to need least one traditional valve surgery are better off having the surgery in their 60s rather than in their 70s. A TAVR can be done the second time around.

Harvard Medical School professor Dr. Eugene Braunwald, known as "the father of modern cardiology," identified five promising future trends in cardiology. They include (1) using polygenic risk scores in newborns for early prevention of heart disease; (2) the emergence of a battery of drugs to treat inflammation; (3) improvements in cardiac cell therapy for repairing damaged hearts; (4) the development of smaller, more powerful, and less expensive left ventricular assist devices; and (5) transplanting genetically modified pig hearts into humans.

According to a 2023 study, a person's waist-to-hip ratio-the circumference of the waist divided by the circumference of the hip-is a better predictor of future health issues like high blood pressure, heart disease, and type 2 diabetes than body mass index.

A 2023 analysis suggests that men older than age 70 can fight declining testosterone levels by engaging more in healthy lifestyle behaviors like increasing exercise, losing weight, and managing high blood pressure.

Dietary choices can influence weight, blood pressure, cholesterol levels, and blood sugar levels, all factors that can determine a person's risk for heart disease, heart attack, and stroke. Adopting certain eating habits can help manage these factors. These include reducing the intake of saturated fat and refined sugar that are included in many processed foods, eating more healthy monounsaturated and polyunsaturated fats, and following a plant-based diet like the Mediterranean or DASH diet.

Men who report specific types of job-related stress face a higher risk of heart disease than those without such stress, according to a 2023 study.
