Heart disease is a result of plaque buildup in your coronary arteries -- a condition called atherosclerosis -- that leads to blockages. The arteries, which start out smooth and elastic, become narrow and rigid, restricting blood flow to the heart. Signs and symptoms depend on the type of heart block you have. First-degree heart block may not cause any symptoms. Signs and symptoms of second-and third-degree heart block include: 1  Fainting. 2  Dizziness or light-headedness. 3  Fatigue (tiredness). 4  Shortness of breath. I'd like to begin with clearing the biggest misconception about heart blockage-it is not a disease. On the contrary, it is one of the major symptoms of coronary artery disease and among the most prominent signs of deteriorating heart health. And, sometimes, women may have a heart attack without chest pains. Women are more likely than men to have heart attack symptoms unrelated to chest pain, such as: 1  Neck, jaw, shoulder, upper back or abdominal discomfort. 2  Shortness of breath. 3  Right arm pain. 4  Nausea or vomiting. 5  Sweating. First-degree heart block may not cause any severe symptoms. Second-degree heart block may result in the heart skipping a beat or beats. This type of heart block also can make you feel dizzy or faint. Third-degree heart block limits the heart's ability to pump blood to the rest of the body. Coronary artery disease, also called coronary heart disease, or simply, heart disease, is the No. 1 killer in America, affecting more than 13 million Americans. Heart disease is a result of plaque buildup in your arteries, which blocks blood flow and heightens the risk for heart attack and stroke.
