Answer: What are the risk factors for cardiovascular disease?
About half of all Americans (47%) have at least 1 of 3 key risk factors for heart disease: high blood pressure, high cholesterol, and smoking. Some risk factors for heart disease cannot be controlled, such as your age or family history.
Signs and symptoms can include:
Chest pain, chest tightness, chest pressure and chest discomfort (angina)
Shortness of breath.
Pain, numbness, weakness or coldness in your legs or arms if the blood vessels in those parts of your body are narrowed.
Pain in the neck, jaw, throat, upper abdomen or back.
