Introduction and Objectives: Significant impairment of the left main coronary artery is the most lethal presentation of coronary artery disease. The treatment of choice is coronary artery bypass surgery. In several multicenter studies, the possibility of treating coronary artery disease by percutaneous coronary intervention with implantation of endoluminal prosthesis or stent is suggested. The objective of this research was to characterize percutaneous angioplasty with stent in the left main coronary artery. Method: An observational, descriptive and transversal study was carried out in 21 patients with percutaneous angioplasty with stent in the left main coronary artery, performed in the laboratory of Hemodynamics and Interventional Cardiology of Hermanos Ameijeiras Hospital, between January 2010 and July 2011. Results: There was no significant difference in sex. The age group 50-64 years (47.6%) and white skin color (76.19%) were predominant. The most commonly found cardiovascular risk factor was hypertension (85.71%), followed by dyslipidemia (47.61%). Effort angina was the most observed diagnosis with 14 cases (66.66%). The lesion in the body of the trunk (12 patients, 57.1%) was the most prevalent, followed by ostial lesion (8 cases). Drug-eluting (61.9%) was the most used type of stent and only 4 patients had surgically protected trunks. Conclusions: Most cases were elective, with a predominance of unprotected trunks. Hypertension was the coronary risk factor most commonly found. A significant association between diabetes mellitus and ostial location of the lesion was found.
