Coronary occlusion
Coronary Occlusion
Coronary occlusion (pronunciation: kuh-ROH-nuh-ree uh-KLOO-zhuhn) is a medical term that refers to the blockage or obstruction of a coronary artery. This condition can lead to a myocardial infarction or heart attack due to the lack of blood flow to the heart muscle.
Etymology
The term "coronary" is derived from the Latin word "corona," meaning crown, referring to the crown-like appearance of the coronary arteries as they encircle the heart. "Occlusion" comes from the Latin word "occludere," which means to close up or block off.
