LM Coronary Occlusion

Acute LM coronary artery occlusion is a rare clinical event. The exact incidence remains unknown because many patients with acute occlusion die suddently.But in one of the recent large registry reported to be around 4% (1799 of 43018), 1 Clinical presentation can be as sudden cardiac death, but also the whole spectrum of acute coronary syndrome (ACS); such as STEMI, non-ST elevation ACS and unstable angina. One quarter of patients present in cardiogenic shock 2. Although electrocardiography can predict LM occlusion in patients with ACS, the definitive diagnosis is made by coronary angiography. 3 ACS from LM occlusion are associated with significant morbidity and mortality, which can be reduced by early recognition and prompt reperfusion.
