Revision as of 15:49, 9 October 2014

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

The most common proximate cause of ST elevation myocardial infarction is plaque rupture. There are risk factors for plaque rupture and triggers of plaque rupture. A full discussion regarding the chronic risk factors and acute triggers of ST elevation MI can be found in other chapters. While plaque rupture is the most common cause of ST segment elevation MI, other conditions can cause ST elevation and myocardial necrosis. In order to expeditiously treat an alternate underlying cause of myonecrosis, it is important to rapidly identify conditions other than plaque rupture that may also cause ST elevation and myonecrosis. Indeed, the management of some of these conditions might differ substantially from that of plaque rupture: cocaine induced STEMI would not be treated with beta-blockers, and myocardial contusion would not be treated with an antithrombin. These conditions include the following:

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.
