Sleep apnea and heart disease: A weighty matter

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.

Incorrect arm position may skew blood pressure readings

Letting your arm dangle or rest in your lap (instead of being supported at heart level, as is recommended) during a blood pressure check can cause a falsely high reading, according to a 2024 study.

An often-silent liver condition that threatens the heart

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.

Under-the-radar heart risks

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.

"Teleprehabilitation" reduces problems after heart surgery

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.

Flavonoid-rich diet linked to lower risk of plaque in neck, leg arteries

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.

What's the right blood pressure?

U.S. guidelines define normal blood pressure as less than 120/80 millimeters of mercury (mm Hg). Studies have shown that the lower a person's blood pressure, the greater the heart health benefits. However, the "best" blood pressure number for someone depends on several factors, such as the person's health condition, lifestyle, family history, and personal goals. Depending on an individual's situation, a higher-than-normal number may be adequate.

Is snow shoveling safe for people with heart disease?

Snow shoveling can be risky for people with heart disease because (1) the activity requires a lot of physical effort, and (2) cold temperatures constrict arteries. Both factors can raise the risk of a heart attack in people with narrowed heart arteries.

Tracking your afib with a smart watch? Avoid this pitfall

People with atrial fibrillation (afib) who own a smart watch capable of detecting the heart rhythm disorder may use it to track the frequency and duration of their bouts of afib. The information might help inform their physician's advice. However, afib notifications may cause people to become anxious and preoccupied with tracking their condition. For them, disabling the notifications may be a good idea.

The latest thinking on inherited high cholesterol

About 5% of Americans have low-density lipoprotein (LDL) values of 190 mg/dL or higher. Their risk of heart disease is five times higher than people with near-optimal values (less than 130 mg/dL). Some have familial hypercholesterolemia, a genetic condition that can lead to LDL values up to 350 mg/dL (or even higher in some cases). Known as FH, it's a common cause of early heart attacks.
