Oxygen-poor blood from the body enters your heart through two large veins called the superior and inferior vena cava. The blood enters the heart's right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs.
Coronary heart disease is a type of heart disease that occurs when the arteries of the heart cannot deliver enough oxygen -rich blood to the heart muscle due to narrowing from the buildup of fatty deposits called plaque . It is also sometimes called coronary artery disease or ischemic heart disease.
Your risk of coronary heart disease increases based on the number of risk factors you have and how serious they are. Some risk factors — such as high blood pressure and unhealthy cholesterol levels can be adjusted through heart-healthy lifestyle changes. Other risk factors, such as your age, family history, and race and ethnicity, cannot be changed.
Overview Cardiomyopathy (kahr-dee-o-my-OP-uh-thee) is a disease of the heart muscle.

A heart attack occurs when an artery that sends blood and oxygen to the heart is blocked. Fatty, cholesterol-containing deposits build up over time, forming plaques in the heart's arteries. If a plaque ruptures, a blood clot can form. The clot can block arteries, causing a heart attack. During a heart attack, a lack of blood flow causes the tissue in the heart muscle to die.
Coronary artery disease, other heart problems and previous heart surgery. Narrowed heart arteries, a heart attack, heart valve disease, prior heart surgery, heart failure, cardiomyopathy and other heart damage are risk factors for almost any kind of arrhythmia.
Take Action Toward Better Heart Health: Eat a Heart-Healthy Diet A healthy diet that is low in sodium and saturated fat is key to heart disease prevention. Try the highly rated Dietary Approaches to Stop Hypertension (DASH) eating plan. It recommends: Eating vegetables, fruits, and whole grains
