Risk Factors for Heart Disease

Some risk factors for heart disease are under your control and some are not. Coronary artery disease causes roughly 1.2 million heart attacks each year, and more than forty percent of those suffering from a heart attack will die. Even more worrisome, 335,000 people with heart attacks will die in an emergency department or before ever reaching the hospital. According to the American Heart Association, over 7 million Americans have suffered a heart attack in their lifetime.

What Are the Risk Factors for Heart Disease?

There are several risk factors for heart disease; some are controllable, others are not. Uncontrollable risk factors include:

  • Male sex
  • Older age
  • Family history of heart disease
  • Post-menopausal
  • Race (African Americans, American Indians, and Mexican Americans are more likely to have heart disease than Caucasians)

Still, there are many heart disease risk factors that can be controlled. By making changes in your lifestyle, you can actually reduce your risk for heart disease. Controllable risk factors include:

What Can I Do to Lower My Risk of Heart Disease?

Making changes in your lifestyle is a proven method for reducing your risk of heart disease. While there are no guarantees that a heart-healthy lifestyle will keep heart disease away, these changes will certainly improve your health in other ways, such as improving your physical and emotional well being. Also, because some risk factors are related to others, making changes in one area can benefit other areas.

Here are some ways you can reduce your risk of heart disease.

  • Quit smoking. Smokers have more than twice the risk for heart attack as nonsmokers. If you smoke, quit. Better yet, never start smoking at all. Nonsmokers who are exposed to constant smoke (such as living with a spouse who smokes) also have an increased risk. So taking measures to eliminate this exposure to smoke is important.
  • Improve cholesterol levels. The risk for heart disease increases as your total amount of cholesterol increases. In general, your total cholesterol goal should be less than 200 mg/dl; HDL, the good cholesterol, higher than 40 mg/dl in men and 50 mg/dl in women (and the higher the better); and LDL should be less than 130 mg/dl in healthy adults. People with coronary artery disease, diabetes, or an LDL > 190 mg/dl are recommended to take a statin, as are people with an estimated 10-year risk of heart attack greater than 7.5%. Interpretation and treatment of cholesterol values must be individualized, taking into account all of your risk factors for heart disease. Your doctor may use a calculator to help determine your risk. A diet low in cholesterol, saturated and trans fat, and simple sugars will help lower cholesterol levels and reduce your risk for heart disease. Regular exercise will also help lower "bad" cholesterol and raise "good" cholesterol. Medications are often needed to reach cholesterol goals.
  • Control high blood pressure. About 60 million people in the U.S. have hypertension, or high blood pressure, making it the most common heart disease risk factor. Nearly one in three adults has systolic blood pressure (the upper number) over 140, and/or diastolic blood pressure (the lower number) over 90, which is the definition of hypertension. Like cholesterol, blood pressure interpretation and treatment should be individualized, taking into account your entire risk profile. Control blood pressure through diet, exercise, weight management, and if needed, medications.
  • Control diabetes. If not properly controlled, diabetes can contribute to significant heart damage, including heart attacks and death. Control diabetes through a healthy diet, exercise, maintaining a healthy weight, and taking medications as prescribed by your doctor.
  • Get active. Many of us lead sedentary lives, exercising infrequently or not at all. People who don't exercise have higher rates of death and heart disease compared to people who perform even mild to moderate amounts of physical activity. Even leisure-time activities like gardening or walking can lower your risk of heart disease. Most people should exercise 30 minutes a day, at moderate intensity, on most days. More vigorous activities are associated with more benefits. Exercise should be aerobic, involving the large muscle groups. Aerobic activities include brisk walking, cycling, swimming, jumping rope, and jogging. If walking is your exercise of choice, use the pedometer goal of 10,000 steps a day. Consult your doctor before starting any exercise program.
  • Eat right. Eat a heart-healthy diet low in salt, saturated fat, trans fat, cholesterol, and refined sugars. Try to increase your intake of foods rich in vitamins and other nutrients, especially antioxidants, which have been proven to lower your risk for heart disease. Also eat plant-based foods such as fruits and vegetables, nuts, and whole grains.
  • Achieve and maintain a healthy weight. Excess weight puts significant strain on your heart and worsens several other heart disease risk factors such as diabetes, high blood pressure, and high cholesterol and triglycerides. Research is showing that obesity itself increases heart disease risk. By eating right and exercising, you can lose weight and reduce your risk of heart disease.
  • Manage stress. Poorly controlled stress and anger can lead to heart attacks and strokes. Use stress and anger management techniques to lower your risk. Learn to manage stress by practicing relaxation techniques, learning how to manage your time, setting realistic goals, and trying some new techniques such as guided imagery, massage, Tai Chi, or yoga.
