Abstract

History and Objectives: Considering the prevalence of coronary artery therosclerosis and its significant complications such as myocardial infarction, and its high rate motality and special involvment of the main left coronary artery division which includes higher mortality rate and the successful by-pass surgery compared to drug treatment and and assessment of relationship of risk factors regarding the presence or absence of clinical signs and the study of its condition and stenosis of LMCA and its relationship with other stenosis in different parts of left and right coronary, the present study was carried out on patients referred to Dr. Shariati Hospital for coronary vessel angiography between 1990-1994. Materials and Methods: A descriptive study was conducted on existing patients file from Dr. Shariati Hospital for whom coronary angiography was performed for the past five years. There was no preclinical or clinical evidence of rhomatic diseases or congenital heart disease and patients who were suffering from LMCAD were selected. Personal records, clinical signs, cardiovascular risk factors and angiographic results were extracted. Results: From the total of 1479patients, 10% had LMCAD. 94% of the patients had clinical signs such as pain or dyspnea. The most prevalent risk factor was hyperlipidemia (in 60% of cases). Hypercholesterolemia was the most common risk factor associated with the disease (60%) and increased arterial pressure was the least prevalent associated risk factor (2.5%). The distal region narrowing in LMCA with 75% was the most frequent and in ostium it was the least frequent. The distribution of LMCA was in trunk lenght (11%), and 2% in middle section (6%), in proximal section (5%) and in the form of ectalic (2%). The distribution of the intensity of narrowing in LMCA shows that the most frequent relates to 30% narrowing and the least rates relates to obstructions over 90%. In other words, 55% of the patients 40% have narrowing or more. In inspecting the relationship between the MCAD and narrowing in other parts, the most frequent narrowing was associated in CX-artery with 79% of the cases and in descending proximal artery in 75% of cases, in distal region with 13% and in descending posterior artery with 19% of prevalence. Conclusions: The narrowing of coronary artery particularly in the main trunk is a common disease with high mortality rate. The characterization of angiography and its relationship with the narrowing in other parts of angiography relationship between this type of narrowing with narrowing the once in other parts of coronary artery results in identification of LMCAD.
