When participants in a 2023 study ate a low-sodium diet for one week, the vast majority experienced an average 8-point drop in their systolic blood pressure compared to when they ate a high-salt diet for one week.

Many people who suffer a first-time stroke had a prior warning from a transient ischemic attack (TIA), also known as a ministroke. TIAs can last anywhere from 30 seconds to 20 minutes, although most usually last at least five minutes. TIAs usually have typical stroke symptoms, but because they are mild and brief they tend to be missed or ignored. People should seek immediate medical care after an attack.

A significant reduction in salt intake may directly lower blood pressure in even more people than previously believed.

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).

Orthostatic hypotension, a condition that causes blood pressure to drop when a person stands up, can leave people dizzy and lightheaded. It can result from certain medications or health problems and becomes more common with age and frailty. Doctors sometimes worry that intensive blood pressure treatment contributes to the problem, but research suggests the opposite is true. Strategies to cope with symptoms of orthostatic hypotension include drinking plenty of fluids, wearing compression stockings, and taking care when rising from a chair or bed.

When people with atrial fibrillation sleep poorly, they may be more likely to have an episode of atrial fibrillation the next day, according to a 2023 study.

Walk with a Doc is a nonprofit program founded by a cardiologist that sponsors free, doctor-led walks in mostly outdoor venues (usually public parks) in 560 sites across America. The walks last 30 to 90 minutes, are usually held once per month, and include a five-minute talk about various health topics by the physician. In addition to the exercise and education, participants benefit from the camaraderie and time spent in nature.

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.

In contrast to previous studies, several new investigations have been unable to find clear evidence that people who take a drink a day are less likely to develop heart disease than people who don't drink. The new evidence doesn't negate past studies; it simply must be weighed against past studies. And while findings suggest that moderate drinking may offer some heart benefits, drinking is not recommended for the purpose of achieving those unproven benefits. Excessive drinking—averaging three or more drinks a day—causes multiple health problems, including heart problems.

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.
