The term “heart disease” refers to multiple types of heart conditions. The most common type of heart disease is coronary artery disease (CAD), which may affect the blood flow to the heart. Decreased blood flow can cause a heart attack.
Sometimes heart disease may be “silent” and not diagnosed until a person experiences signs or symptoms of a heart attack, heart failure, or an arrhythmia. When these events happen, symptoms may include1
Heart attack: Chest pain or discomfort, upper back or neck pain, indigestion, heartburn, nausea or vomiting, extreme fatigue, upper body discomfort, dizziness, and shortness of breath.
Arrhythmia: Fluttering feelings in the chest (palpitations).
Heart failure: Shortness of breath, fatigue, or swelling of the feet, ankles, legs, abdomen, or neck veins.
High blood pressure, high blood cholesterol, and smoking are key risk factors for heart disease. About half of people in the United States (47%) have at least one of these three risk factors. 2 Several other medical conditions and lifestyle choices can also put people at a higher risk for heart disease.
