Compared with people who sit for eight hours daily, people who sit more than 12 hours a day may be more likely to die prematurely. But just 22 minutes of brisk walking or similar activity daily may offset that risk, according to a 2023 study.

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.

A 2023 study of 1.5 million people found that those who had uncontrolled high blood pressure or diabetes prior to getting COVID-19 had increased risks for COVID complications (such as hospitalization or being on a ventilator), compared with people whose high blood pressure or diabetes was well controlled.

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.

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.

For preventing repeat heart attacks, coated aspirin is just as effective as regular aspirin, but it does not appear to provide extra protection against bleeding risk.

Up to three in 10 people who use marijuana may be unable to stop using the drug, even when it has negative effects on their lives. A 2023 study links this problem- known as cannabis use disorder-to a higher risk of heart problems.

In women, sleep problems-including falling asleep, staying asleep, and insufficient sleep-were associated with a greater risk of high blood pressure.

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.

Diets high in added sugars are linked to an increased risk of coronary artery disease, but naturally occurring sugars in fruits and vegetables are not. Nearly 70% of added sugar in the American diet comes from sugary beverages, desserts and sweet snacks, candy, and breakfast bars and cereals. Consuming excess added sugar promotes weight gain and diabetes and also spurs the liver to pump out triglycerides and other fats into the bloodstream.
