A wearable sensor no bigger than a postage stamp can capture detailed images of the heart, even when a person is exercising. The technology may one day make high-quality cardiac imaging more widely accessible to a larger population.

People who experience stroke symptoms that disappear in less than an hour, a phenomenon known as a transient ischemic attack, should seek immediate care to prevent a full-blown stroke.

Medication to lower high blood pressure is a proven way to reduce a person's risk for heart disease. But adopting lifestyle changes may let people maintain healthy readings and perhaps even avoid drug therapy. Six lifestyle changes have the most significant influence on blood pressure: diet, exercise, weight control, limiting sodium and alcohol, and managing stress.

While the focus is often on avoiding unhealthy foods, adding in nutritious options can be a means of protecting and improving your heart health. Olive oil, mixed nuts, multicolored fruits and vegetables, fatty fish, and sources of soluble fiber are options to try.

People younger than 65 with a bicuspid aortic valve who develop aortic stenosis may need open heart surgery to replace the valve. A less invasive procedure isn't possible for several reasons, including challenges related to the valve anatomy.

Obstructive sleep apnea is a condition marked by brief pauses in breathing, often triggering loud snoring, grunts, gasps, and choking noises. Because sleep apnea can put stress on your heart and circulation, it's important to learn the signs and symptoms and get treatment.

A sugary diet contributes to weight gain and other factors that boost heart disease risk, including inflammation, disrupted blood sugar control, and increased cholesterol. The typical American diet is very high in added sugar, nearly half of which comes from sugar-sweetened beverages. Another 30% comes from baked goods such as cookies, brownies, cakes, pies, doughnuts, sweet rolls, and pastries. People don't need to completely give up sweet treats but should enjoy them just once or twice a week rather than daily.

What people choose to eat has a big impact on their cardiovascular health. The dietary habits of the nation as a whole also have a major effect on the country's economic health. About 45% of the costs associated with heart disease, stroke, and diabetes is related to unhealthy diets. The dietary habits that appear to have the biggest effect are not eating enough nuts, seeds, and seafood omega-3 fatty acids. Among foods to avoid, sugary beverages and processed meats seem to contribute the most to higher costs. Each year, unhealthy diets cost the United States an average of about $300 per person in medical costs, which translates to $50 billion nationwide.

Over the past decade, nutrition experts have shifted away from recommending a low-fat diet to focusing more on an overall healthy dietary pattern. This eating style, which includes lots of plant-based foods, is naturally low in saturated fats. Found mainly in meat and dairy products, saturated fat can boost levels of harmful LDL cholesterol, a key contributor to heart disease. Cutting back on all types of fat does not necessarily translate into a diet that lowers cardiovascular risk. The plant-centric Mediterranean eating pattern, which is rich in healthy unsaturated fats found in nuts, seeds, and olives, has the best evidence for lowering heart disease risk.

Coronary artery calcium scans tend to be quite accurate. Unlike some other imaging tests, the results are unlikely to be either falsely negative or falsely positive because the results are literally black and white (the calcium shows up as white on the scan).
