An inferior infarct is a heart attack caused by loss of blood flow in the bottom section of the heart's left ventricle, the chamber mainly responsible for pumping, explains HealthCentral. This loss of blood often results from blockage within the right coronary artery providing blood to the lower left ventricle.
Infarct, which is short for infarction, implies that a certain tissue within the body has stopped receiving blood and consequently ceases to function, according to HealthCentral. For example, a cerebral infarction refers to a stroke, while a myocardial infarction refers to a heart attack. An inferior infarct, also known as an inferior wall infarct, therefore, pertains to a type of myocardial infarction involving the left ventricle's inferior wall, or the bottom of the heart.
According to the National Heart, Blood, and Lung Institute, heart attacks are the leading cause of death in the United States, with almost 1 million people experiencing heart attacks each year. The primary cause of heart attacks is coronary heart disease, which is a condition where plaque builds up inside the arteries over many years. The plaque can break open and form a clot that blocks the artery, causing a heart attack.
