Abstract
Background: The main aim of the study is to investigate the prevelance of different risk factors, angiographic patterns undergoing cabg , the within 30 day mortality among cabg groups with left main coronary artery disease incidences and correlating them between on pump cabg group and off pump cabg group
Methods: The present study is a retrospective cross sectional observational study with data from may 2016 to December 2021 undertaken in government general hospital Kurnool. The data considered includes the age, risk factors, echo reports, angiographic data, surgery details and post surgery status. Out of 108 CABG procedures done a total of 20 patients with LM disease where taken of which 10 on pump cabg group patients and 10 off pump cabg group patients where present eligible as per inclusion criteria and exclusion criteria
Results: The mean age of patients was 56.21 ± 10.2 years with maximum age of 85 years and minimum age of 35 years. The distribution of male population was male 17 ( 83.3%) and female population was 3 (16.7%) The persons with smoking as risk factor are 11(55.6%), alcohol as 6 (33.3%), diabetes as 5 (25.9 %) , hypertension as 4 (17.6%). Some of them have more than one risk factors. The mean ejection fraction of the patients were 43.66 ± 6.2 with highest ejection fraction noted was 63 and lowest was 30.The patients with left main coronary artery disease with single vessel disease are 3 (15%), double vessel disease are 13 (65%), triple vessel disease are 4 (20%). Of the 10 patients undergone on pump cabg 6 patients (60%) of patients died and of the 10 patients under gone off pump cabg 2 (20%) died
Conclusion: The patients with left main involvement with other vessels had higher mortality among on pump group in addition with triple vessel diseases. Smoking and alcohol and higher age are more contributing for mortality in on pump and off pump group more in on pump group.
