Nearly 40% of patients presenting with Non ST-Segment Elevation Myocardial Infarction (NSTEMI) have Chronic kidney disease (CKD).CKD is a powerful predictor of adverse events among NSTEMI patients. CKD patients have a high prevalence of obstructive coronary artery disease. Several studies have been conducted in the past outside Bangladesh but correlation between CKD and outcome in patients with NSTEMI has not been studied in our country. No prior studies have examined the independent association of CKD with coronary anatomy also. Rapid risk stratification is crucial for appropriate management of these patients and for targeting more potent and invasive therapies for higher risk patients. So this study has been designated to evaluate the effect of renal dysfunction on coronary artery disease profile and in-hospital clinical outcome in NSTEMI patients.
