A short episode of anger may have adverse effects on the cells lining the blood vessels, according to a 2024 study. The findings may help explain the long-observed link between negative emotions and an increased likelihood of cardiovascular problems.

Doctors may diagnose heart attacks in people who have not actually had one, in part because they screen people with subtle symptoms out of fear of missing the diagnosis. Failure to diagnose a heart attack is the No. 1 cause of malpractice payouts in the emergency department. But the blood test used to detect a heart attack is very sensitive, and other conditions such as myocarditis (heart inflammation) may be misdiagnosed as a heart attack. This problem of overdiagnosis can expose people to unneeded risks, high costs, and other downsides.

A 2024 study suggests that for people with atrial fibrillation (afib), heart failure may be a more common complication than stroke. People with afib should be vigilant for the early warning signs of heart failure, such as feeling tired and winded.

People can reduce their LDL cholesterol in three ways. One strategy involves dietary changes, such as eating more fiber-rich foods and swapping saturated fats for unsaturated fat. Another is to take one of several dietary supplements, including psyllium, plant sterols, or red yeast rice. The third entails taking a prescription medication, such as a statin. Many factors can affect whether these different strategies are advisable or useful, including a person's age and other risk factors for heart disease, their current dietary habits, and the quality of the supplements they take.

Beta blockers remain effective medicines for treating and managing common heart disease problems. People take them to manage atrial fibrillation (an irregular and rapid heart rhythm) and to prevent chest pain from coronary artery disease. Beta blockers also are used in the initial treatment of heart attacks. However, many people who have a mild heart attack may not need to take one forever.

A 2024 study suggests that the more alcohol people drink-whether they imbibe beer, wine, or hard liquor-the higher their blood pressure.

Chest pain is an indicator of a possible heart attack, but it may also be a symptom of another condition or problem. The type and location of the pain can help doctors determine what is causing it.

A large observational study published in 2024 suggests that stroke isn't the biggest risk of atrial fibrillation (an abnormal heart rhythm condition). The biggest risk seems to be heart failure, a condition in which the heart is unable to pump blood effectively.

A 2024 study suggests using cannabis weekly may be associated with an increase in people's risks of heart attack and stroke, and the risks rise dramatically with more frequent use.
