Risk factorsBy Mayo Clinic Staff
Factors that can increase your risk of developing myocardial ischemia include:
July 25, 2015
- Tobacco. Smoking and long-term exposure to secondhand smoke can damage the inside walls of arteries. The damage can allow deposits of cholesterol and other substances to collect and slow blood flow in the coronary arteries. Smoking also increases the risk of blood clots in your coronary arteries.
- Diabetes. Type 1 and type 2 diabetes are linked to an increased risk of myocardial ischemia, heart attack and other heart problems.
- High blood pressure. Over time, high blood pressure can accelerate atherosclerosis, resulting in damage to the coronary arteries.
- High blood cholesterol level. Cholesterol is a major part of the deposits that can narrow your coronary arteries. A high level of "bad" (low-density lipoprotein, or LDL) cholesterol in your blood may be due to an inherited condition or a diet high in saturated fats and cholesterol.
- High blood triglyceride level. Triglycerides, another type of blood fat, may also contribute to atherosclerosis.
- Obesity. Obesity is associated with diabetes, high blood pressure and high blood cholesterol levels.
- Waist circumference. A waist measurement of more than 35 inches (89 centimeters) for women and 40 inches (102 cm) in men increases the risk of high blood pressure and heart disease.
- Lack of physical activity. An inactive lifestyle contributes to obesity and is associated with higher cholesterol and triglyceride levels. People who get regular aerobic exercise have better cardiovascular fitness, which is associated with a decreased risk of myocardial ischemia and heart attack. Exercise also lowers high blood pressure.
