• Eating a heart-healthy diet that is low in fats and oils and cholesterol.

  • A routine regimen of moderate exercise, depending on an individual's overall health, is invaluable in maintaining a healthy cardiovascular system. Exercise keeps obesity at bay and strengthens the heart. It also lowers cholesterol levels and blood pressure. Furthermore, when accompanied by a low-fat diet, exercise may help to reduce plaque deposits, reversing atherosclerosis. Even low-intensity leg exercises have shown benefit in relieving shortness of breath, particularly in heart failure patients in whom shortness of breath is a typical symptom.

  • Quitting smoking is critical for all smokers. People who smoke usually find that they experience regular shortness of breath. This may be caused by impairment of the lungs, the heart or both. Research from the U.S. Centers for Disease Control and Prevention (CDC) finds that smoking results in about 150,000 deaths from cardiovascular disease each year.

  • Controlling diabetes.

  • Controlling high blood pressure (hypertension).

  • Getting regular physical examinations, particularly if in a high-risk category for heart disease, can be an effective early warning system.
