Risk Factors For Premature Atrial Contractions

Coronary Heart Disease

When the blood vessels responsible for supplying oxygenated blood to operate the heart muscle become narrowed and clogged, it is called coronary heart disease. The coronary arteries that get narrowed and blocked exist on the heart's surface and do not refer to the arteries the heart uses to pump blood to the other body parts. When the coronary arteries are restricting adequate blood flow to the heart muscle tissues themselves, those tissues do not receive the proper amount of oxygen to function normally. This causes the electrical pathway and patterns of the impulses that regulate the heartbeat to get interrupted or even stop altogether. It is the oxygen shortage induced interference that will frequently cause a number of arrhythmias to occur, including premature atrial contractions. Efforts to treat coronary artery disease symptoms with medication, lifestyle changes, or surgery can help reduce the occurrence of premature atrial contractions and other types of cardiac arrhythmias, though there is no actual cure. Therefore, individuals who have coronary heart disease will always have an increased risk of experiencing premature atrial contractions.
