Background: Left Coronary Trunk Obstructive Disease (LCID) is a serious cardiovascular condition due, generally, to atherosclerosis, it is the most serious and the one with the worst prognosis, since it supplies between 70 and 100% of the heart's blood. Acute coronary syndrome (ACS) is very broad and includes everything from cardiac arrest, electrical or hemodynamic instability with cardiogenic shock caused by ischemia or mechanical complications, to patients whose chest pain has already disappeared when they arrive at the hospital.
Methodology: A narrative review was carried out through various databases from January 2015 to May 2021; the search and selection of articles was syndrome, trunk disease, left trunk obstructive disease, "the inch of god".
Results: Acute coronary syndrome (AIS) secondary to the complication of atheromatous plaque at the level of the coronary artery is rare and is associated with high morbidity and mortality. Medically treated patients with this disease have a mortality rate that reaches 50% in the following 3 years. In most cases, the lesion is located in the distal portion.
Conclusions: The present review offers a close association between acute coronary syndrome, atherosclerosis, plaque erosion or fissure associated with thrombus formation, in the microcirculation (paradoxical vasoconstriction), and coronary artery disease.
