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. 3  They can lead to rapid heartbeat, lightheadedness, dizziness, fainting and sometimes sudden death.
