The PREVENT equation is a new online calculator to predict a person's odds of developing heart disease. Compared to previous calculators, the updated tool considers broader measures of health (including biomarkers for kidney and metabolic health) and a longer age span (starting at 30 instead of 40 years of age). The goal is to encourage earlier, more targeted strategies to help people avoid cardiovascular problems.

A 2023 study suggests replacing a daily serving of processed meats with whole grains, nuts, or beans is associated with lower odds of cardiovascular conditions such as heart attack or stroke.

Replacing just five minutes of sitting with moderate-to-vigorous physical activity may lead to tangible improvements in cardiovascular health. Adding longer, more intense bouts of exercise can reap greater rewards. But even modest changes such as replacing sitting with standing may lead to positive changes in health parameters, including improvements in body mass index, waist circumference, cholesterol, triglycerides, and blood sugar levels.

Calcium deposits in the coronary arteries surrounding the heart may be a sign of fatty plaque buildup in arteries. Dietary calcium is not a cause of these calcium deposits. While people can't reverse the effect of calcium deposits, they can slow the process by managing blood pressure and "bad" LDL cholesterol.

A long-term study published in 2023 found that watching lots of television during young adulthood was linked to increased rates of obesity and other factors that raise heart disease risk in midlife.

Treatments for angina include medications to lower LDL cholesterol to very low levels to help reduce artery-narrowing plaque. Drugs that slow the heart rate and widen arteries can improve symptoms.

Clinical trials are under way using gene therapy to treat inherited cardiovascular conditions, including familial hypercholesterolemia (one form of abnormally high cholesterol), hypertrophic cardiomyopathy (a type of heart muscle disease), and transthyretin amyloid cardiomyopathy (a form of heart failure resulting from amyloid deposits). But challenges remain in developing and delivering these therapies.

People whose spouses have high blood pressure may be more likely to have high blood pressure themselves than people whose spouses do not have the condition, according to a 2023 study.

Tiny mesh tubes called stents, used to prop open heart arteries, can relieve stable angina (chest pain with exertion or emotional stress) in many people with coronary artery disease. But this treatment-which carries a risk of complications and a high cost-should be reserved only for people who don't get relief from drug therapy. Stents do not prevent future heart attacks or improve survival compared with drug therapy. Angina usually results from arteries that are more than 70% blocked, but most heart attacks occur in arteries that are narrowed by only about 40% or less but harbor plaque that ruptures without warning. The resulting blood clot blocks blood flow, triggering a heart attack.

A 2023 study suggests that following a healthy vegan diet may improve cardiometabolic risk factors (such as LDL cholesterol and weight) more than eating even a healthy omnivorous diet.
