Abstract


Background:   Qrbb myocardial infarction has high mortality and morbidity. So we want to study in hospital outcome of qrbbb myocardial infarction

Methods:  It is a prospective study. We studied qrbbb mi patients admitted in our hospital from December 2016 to June 2017

Results:  About 90% of patients had heart failure. And 80% of patients required ventilatory support in the form of non-invasive positive pressure ventilation (NIPPV) or invasive ventilation. About 37% of patients had ventricular arrhythmias. Thrombolysis with streptokinase was done in 64% of patients and with tenecteplase for 20% of the patients. Percutaneous transluminal coronary angioplasty (PTCA) was done in 47% patients. Two patients had pharmacoinvasive PTCA. 16% of patients were conservatively treated due to late presentation. 24% patients   died during hospital stay while 76% got discharged. 14% of patients had reversal of rbbb wave. 14% had stent thrombosis. 100% of patients had left anterior descending artery (LAD) disease. While 10% had left main coronary artery disease  and 14% had triple vessel disease (TVD), 10% were sent for coronary artery bypass grafting (CABG).

Conclusions:  qRBBB AWMI carries high mortality of 24% with 90% of patients going in to heart failure. Ejection fraction is a good predictor of death and diabetes is a covariate of predictor of death.
