Clinical presentation of patients with significant left main stenosis

Objectives: Our objective was to evaluate the frequency of clinical presentation in patients with angiographically documented significant LMCA stenosis. Study Design: Cross sectional study. Setting: Department of Cardiac Catheterization and Interventional Cardiology, Punjab Institute of Cardiology Lahore. Period: Six Months from July to December 2018. Results: The mean age of presentation of disease was 59.78±5.76 year, 100 being males (58.82%) and 70 females (41.18%). Regarding frequency of distribution of symptoms, the most common symptom was chest pain. ST segment depression was most common finding (52.94%) on ECG. 50% of patients presented with stable angina,29.41% with unstable angina,8.82% with NSTEMI and 11.76% with STEMI.40% had pulmonary edema at initial presentation. Conclusion: LMCA stenosis is more common in males associated with severe disease in other coronary arteries. Isolated left main disease is rare and is more common in females as compared to males. Atherosclerosis was the major cause LMCA stenosis in the studied population. Severe forms of angina along with diffuse ST depression in multiple ECG leads are common findings in patients with LMCA stenosis.
