Infraction and infarction are two words that are very close in spelling and pronunciation, but have different meanings. We will examine the definitions of infraction and infarction, where they came from and some examples of their use in sentences.

An infraction is a violation of the rules or the law, an infringement upon the rules or the law. Infraction is a noun. The verb form is infract, though it is rarely used. Related words are infracts, infracted, infracting. The word infraction is derived from the Latin word infractionem, which means a breaking or a weakening.

An infarction is a blockage of the blood supply to an organ in a body, perhaps because of a thrombus or blood clot that has formed in a vein, or an embolus which is any foreign matter that is too large to pass through a vein, like a portion of a blood clot, fat, air, or a tumor. An infarction causes tissue to die due to lack of oxygen. The most commonly discussed type of infarction is a myocardial infarction, or a heart attack. When either of the coronary arteries becomes blocked, blood flow is affected and portions of the heart muscle may be deprived of oxygen, which is called cardiac ischemia. Surgery may be necessary to bypass the blockage in the vessels, known as coronary artery bypass surgery. Imaging of the cardiovascular system, perhaps through angiography, will pinpoint the occlusion where the thrombosis or embolism has occurred. The diagnosis will let the cardiac surgeon know what the coronary problem is. Symptoms of a myocardial infarction include chest pain, shortness of breath, dizziness and nausea. Acute angina is often treated with nitroglycerin, though a patient in a full-blown infarction event generally is administered heparin. Complications of a myocardial infarction include arrhythmia, stroke, and heart failure. The word infarction is derived from the Latin word infarcire, which means to stuff in. Infarction is a noun. Infarct is another noun which means the dead tissue resulting from an infarction.
