Cardiovascular diseases affect your heart or your blood vessels. High blood pressure (also known as hypertension), stroke and heart failure are types of cardiovascular diseases. So is coronary heart disease, which includes heart attack and chest pain (angina pectoris).
High levels of cholesterol can increase your risk for heart disease and stroke. Blood tests check your cholesterol and other blood fat (lipid) levels and will tell if you have high cholesterol.
Also, your doctor can ask you a series of simple questions to see if you are at risk for developing heart disease. If so, your doctor can help you learn ways to make lifestyle changes, like changing your diet or using aspirin, to help lower your cholesterol and stay healthy.
