The age-related drop in sex hormone levels can cause undesirable symptoms such as hot flashes or a flagging sex drive. Various formulations of estrogen or testosterone can ease those symptoms, but hormone therapy has a mixed record when it comes to cardiovascular safety. A 2023 study suggests that testosterone therapy is safe for men at high risk for heart disease. But women at high risk for heart disease But women at high risk for heart disease considering estrogen-based therapy need to balance menopausal symptom severity versus the greater chance of an adverse cardiovascular problem.

Men often confront obstacles that keep them from managing heart disease or lowering their risk for it. Harvard cardiologists share the advice they give patients who face challenges in the areas of weight loss, medication management, exercise, and diet. These include thinking about their future health goals, monitoring blood pressure, scheduling workouts, joining group weight-loss groups, and learning portion control for meals.

Lower temperatures, high wind speed, atmospheric pressure, high precipitation, and high degrees of pollution may raise the risk of being hospitalized for serious heart-related conditions. Modeling these factors may help forecast future heart problems.

The cholesterol-lowering drug bempedoic acid (Nexletol) can be a good alternative for people who can't take statins. A 2023 study found that compared with a placebo, bempedoic acid can lower the risk of heart attacks and related problems.

Troponins, which are proteins found in heart muscle cells, are released in the bloodstream during a heart attack. Other conditions, such heart muscle inflammation and chronic kidney disease, can also cause troponin levels to rise.

Following a vegetarian or vegan diet may help lower levels of total and LDL cholesterol, according to a 2023 review of studies published over four decades.

People with autoimmune diseases may be up to three times more likely to develop cardiovascular disease than people without an autoimmune disease. Among the most common autoimmune diseases are rheumatoid arthritis, psoriasis, and lupus. Awareness of this elevated risk is especially important because autoimmune disease typically strikes when people are in their 20s or 30s. In turn, heart problems may develop up to a decade earlier than in people without an autoimmune disease. A calcium scan, which detects early signs of atherosclerosis, can help assess a person's risk and guide treatment advice.

There are two different mechanisms by which most heart attacks happen. Both are related to insufficient blood flow to an area of the heart, most often secondary to fatty plaque buildup in coronary arteries. Chest pain remains the most common heart attack symptom, but others are often subtle, and the underlying process causing the heart attack can differ. It's important for people to recognize the different signs of heart attacks, so they know when to seek immediate medical care.
