Approximately 88 million Americans—more than one in three—have prediabetes, a condition in which the average amount of sugar in the blood (glucose) is high but not high enough to be diagnosed as diabetes. Among people who develop prediabetes, older ones are less likely than younger ones to eventually develop full-blown diabetes. Still, they should have their glucose levels checked, as prediabetes can put them at high risk for heart attack and stroke.

Silent heart attacks often go unnoticed because they don't produce any symptoms or only mild symptoms that are mistaken for something else, such as heartburn or muscle pain. They are thought to make up from 20% to 60% of heart attacks and can raise risk of a future heart attack or related problem. Both women and men are at substantial risk. Making lifestyle changes and being proactive about managing risk factors for heart disease can help prevent future heart-related problems.

A buildup of fat inside the liver, known as nonalcoholic fatty liver disease (NAFLD) affects about 25% of adults. This under-recognized condition is closely linked to obesity (especially excess weight around the middle of the body), type 2 diabetes, and cardiovascular disease. People with NAFLD can slow or even reverse the condition with the same lifestyle strategies that improve cardiovascular health: losing weight, adopting a healthy diet, and exercising regularly.

The typical American diet isn't very healthy, and dietary shortfalls are more pronounced among people living in lower-income neighborhoods. A study analyzing data from produce prescription programs suggests that improving access to fresh vegetables and fruits may improve heart health.

People who get migraines with aura have a slightly higher risk of heart attack, stroke, or death from cardiovascular disease than people who get migraines without aura or no migraines. But migraines are most common in younger women, whose baseline risk of cardiovascular problems is very low in the first place. Still, those who get migraine with aura should be sure to tell their primary care provider or gynecologist. Taking estrogen-containing birth control pills or hormone therapy may further raise stroke risk in these women.

A 2023 study found that most people who are hospitalized for heart failure aren't being referred for cardiac rehabilitation. The rehab is a recommended, medically supervised three-month program (covered by Medicare) that significantly lengthens life.

A 2023 Harvard study found that regularly squeezing a week's worth of exercise (150 minutes) into just one or two days—a "weekend warrior" approach—is linked to the same heart-healthy benefits as daily exercise.

A nasal spray containing the experimental drug etripamil can quickly treat an abnormally fast heart rhythm called supraventricular tachycardia. The disordered rhythm occurs sporadically and can raise heart rate to as much as 200 beats per minute.

Excessive drinking can contribute to high blood pressure, obesity, and stroke, while moderate drinking (no more than one drink per day for women and two drinks or fewer per day for men) is linked to a lower risk of heart problems. One possible mechanism might be stress reduction. Brain scans of people who reported light to moderate drinking show less activity in the part of the brain that responds to stress, compared with the scans of people who abstained or drank very little. Stress not only raises blood pressure and heart rate but also triggers inflammation that causes plaque buildup, which contributes to heart attacks.
