Risk factors are inherited tendencies and learned habits that may increase your risk of having heart disease or speeding up the process. Studies have identified two types of risk factors: uncontrollable and controllable. .

Uncontrollable risk factors: The uncontrollable are the factors in which we have no control.

• Heredity - A parent, brother or sister has had coronary heart disease, a heart attack or coronary surgery (before age 55 in men and before age 65 in women).
• Advancing age - Men above the age of 55-60 and women 65 and older. People age 20 and older should see a doctor every five years to assess risk factors such as smoking, family medical history and blood pressure. People age 40 and older should be screened for additional risk factors, such as blood pressure and total cholesterol.
• Gender - Males continue to be at a higher risk for having heart disease before the age of 65.

• Smoking - Cigarette smoking is the biggest risk factor for sudden cardiac death. Smokers have two to four times the risk of nonsmokers. According to the Framingham Heart Study, nonsmokers live seven to eight years longer than a smoker. Second hand smoke is considered as big a risk factor as smoking.
• High Blood Pressure - Called the "silent killer" since it has few observational symptoms. Normal blood pressure recommendation for all individuals is below 140/90. Anything above that is considered high. Continued high blood pressure can cause damage to the artery walls and increase the cholesterol build up causing plaque (atherosclerosis) in the artery. It also can lead to heart failure.
• Abnormal Blood Lipids (cholesterol levels) - Cholesterol is a fat-like substance found in our cells. It is necessary for cell development. Our bodies produce cholesterol and we also obtain it in our diets by eating animal foods, such as meat, eggs and dairy products. High cholesterol contributes to the build-up of plaque in the artery walls. Recommended total cholesterol is below 200. The ideal is less than 160. Your optimal LDL levels if you have known heart disease is less than 100. When you have no known heart disease the optimal level is between 100-130.
• Overweight - Excess weight can increase your risk for having heart disease. Men who have a waistline of 40 inches or more and women 35 inches or more are at higher risk.
• Physical Inactivity - People who are inactive are at a greater risk for having heart disease. Regular physical activity can help reduce your risk of heart disease, shed extra pounds, control blood pressure, lower blood cholesterol levels and assist with your mental state of being. Being physically active at least 30 minutes a day is recommended by the American College of Sports Medicine and the Centers for Disease Control and Prevention and the American Heart Association.
• Uncontrollable Diabetes - Diabetes, or high blood sugar, can significantly increase the risk of coronary heart disease. Eighty percent of diabetics die from some form of cardiovascular disease.
• Reaction to Stress - Stress may be the greatest single cause of illness in our world. Stress events are often unavoidable, but how we deal with that stress is important to our health. Prolonged emotional stress is likely to accelerate the build-up of plaque along artery walls, cause blood cholesterol and blood pressure to rise and increase susceptibility to illness. Learning to manage stress is essential. Types "A" with the "hot reactor" personalities have a tendency to have a higher risk for heart disease.
