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.

Advice about the amount of physical activity required to stave off heart disease and other chronic ailments is usually expressed as a time-based goal. But counting steps may be just as useful, according to a 2024 study.

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

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.

Chemical pollutants such as lead, perfluoroalkyl and polyfluoroalkyl substances (also known as PFAS), and pesticides may contribute to heart disease risk. Possible routes of exposure for all three include drinking water and food. Residue and dust from many common items (such as water-resistant clothing and personal care products) may expose people to PFAS. People can limit their exposure by testing and, if needed, filtering their drinking water; choosing PFAS-free products when possible; using non-chemical pest control methods; and choosing organic foods.

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.

Circulation problems affect how well arteries and veins function. . Artery problems are marked by diminished oxygen and nutrient rich blood flow to the brain and all other body parts. Related conditions include heart attack, stroke, and peripheral artery disease. Vein problems often arise when valves in the vessels weaken, allowing blood and fluids to pool. That can cause varicose veins, discolored skin on hands or feet, and swollen legs, ankles, or feet.

In a 2024 study of men ages 49 to 76, low levels of testosterone were associated with higher rates of death from any cause and specifically deaths from cardiovascular causes, such as heart attack, cardiac arrest, heart failure, or stroke.
