White-coat hypertension refers to blood pressure that's high only when measured in a medical setting. It's defined as a reading in the doctor's office of greater than 130/80 (but less than 160/100) and an average daytime blood pressure reading of less than 130/80. If home monitoring reveals mostly normal readings, treatment may not be needed. But intermittent blood pressure spikes might still damage the heart.

In a 2024 study, researchers found that the heart rate variability of a dog and its owner mirror each other during interactions, which may reflect the strong emotional connection between humans and their dogs.

About two-thirds of people over 65 have periodontal disease, which is linked to a higher risk of heart disease. Shared risk factors such as smoking and an unhealthy diet may explain the association, but bacteria and inflammation could be a common thread. The bacteria responsible for periodontal disease can travel to blood vessels throughout the body and have been found in the fatty debris (atherosclerosis) that clogs arteries located far from the mouth-and in blood clots from people who have experienced heart attacks.

Research has shown that men can have a higher risk for heart attacks and strokes if they suffer from certain medical conditions that might seem unrelated to heart disease. These conditions include erectile dysfunction, gum disease, peripheral artery disease, and urinary tract infections. Many factors that contribute to heart disease like inflammation and fatty deposits in the arteries are involved in these other conditions.

According to a 2024 study, eating foods rich in beneficial plant compounds called flavonoids may lower the risk of atherosclerosis in the arteries of the legs and neck. Good sources of flavonoids include tea, apples, pears, peaches, and oranges.

A 2024 study of more than 200,000 adults, combined with findings from 19 other studies (for a total of 1.25 million people), tied eating ultra-processed foods-particularly sugary drinks and processed meats-to an increased risk for heart disease.

Anti-obesity drugs, which can lead to dramatic weight loss, may improve symptoms of sleep apnea. This serious breathing disorder raises the odds of high blood pressure, heart attack, and stroke. Excess weight is the strongest risk factor linked with sleep apnea, which affects about 25% of men and 10% of women in the United States. Extra fat tissue in the neck and throat can narrow the airway, and extra weight on the chest and belly puts pressure on the lungs, which makes the normal process of inhaling and exhaling less effective.

Virtual personalized coaching about reducing heart-related risks before heart surgery may reduce complications after surgery, a 2024 study found. Delivered via smartphone, "teleprehabilitation" offers advice on smoking cessation, nutrition, and exercise.

Many Americans may have a potentially serious condition marked by a buildup of fat inside the liver. Known as metabolic dysfunction-associated steatotic liver disease (MASLD), it's closely linked to a higher risk of cardiovascular disease. The root of the problem is usually excess weight-especially the accumulation of belly fat known as abdominal obesity. Weight gain can trigger a host of metabolic problems that cause blood sugar, blood pressure, and cholesterol levels to rise. All of these factors are closely linked to a higher risk of diabetes and cardiovascular disease. Heart disease is one of the common causes of death among people with MASLD.
