Clinical and Angiographic Pattern of Coronary Artery Disease In A Urban Sri Lankan Population.
Introduction: Coronary artery disease (CAD) is a leading cause of mortality worldwide.
Objectives: This study was conducted to describe the clinical and angiographic pattern of CAD in a urban Sri Lankan population.
Methods: We studied consecutive patients of all ages who underwent coronary angiogram done by a single operator in a leading private hospital, Colombo. This study was a retrospective descriptive study conducted among the total number of 352 patients who underwent angiogram from May 2013 to December 2016.
Results: The population with CAD is predominantly male and old (≥41 years). Non-Acute Coronary Syndrome (ACS) is the most common clinical presentation. Triple Vessel Disease (TVD) is most prevalent 136 (38.6%) with the multiplicity of synergistic risk factors. In Single Vessel Disease (SVD), the distribution of disease in LAD, RCA and LCX are 44%, 15% and 8% respectively. Higher rate of ectasia is found in RCA. Diabetes Mellitus (DM) is present in 49% of our patients, which is the second common risk factor next to dyslipidemia (DL) 55% and is significantly associated with TVD.
Conclusion: ST-Elevation Myocardial Infarction (STEMI) is the commonest ACS type in the study group. TVD is more common in old age group whereas SVD is the common pattern in younger population. LAD is the predominantly and severely affected artery among both ACS and non – ACS groups. DL is the commonest risk factor. DM is commonly associated with TVD, which is related to multiple risk factors.
