Causes of Heart Disease. Heart disease occurs when the arteries and blood vessels that lead to the heart are blocked or not carrying blood correctly. When this happens, important nutrients, such as oxygen, cannot reach your heart.ou may not show symptoms of the disease at certain times. Heart disease is sometimes called âcoronary heart diseaseâ or âCHD.â It is the leading cause of death among adults in the United States, according to the National Heart, Lung, and Blood Institute (NHLBI).
1 Coronoary artery disease is the most common cause of heart disease and a leading cause of death in the United States. 2  Coronary artery disease is caused by plaque buildup, plaque rupture or a clot that blocks the coronary arteries, causing a lack of oxygen to the heart, preventing it from functioning effectively. Arrhythmias are diseases that affect the heart's electrical system and the heart's ability to properly squeeze and relax. 2  Hereditary arrhythmias can result in a heartbeat that is too fast, too slow or irregular.
