OUTCOMES OF CABG IN PATIENTS WITH LEFT VENTRICULAR DYSFUNCTION IN KP

Abstract

Objective: To assess the outcomes of CABG in patients with left ventricular dysfunction in KP

Methodology: The current prospective study was conducted from January 2022 to January 2023 at the cardiology department of Khalifa Gul Nawaz Teaching Hospital MTI Bannu and Peshawar institute of Cardiology Peshawar after approval from the ethical review board of the hospital. Those who have undergone planned solitary CABG and LVEF of ˂40% as assessed through echocardiography during the time. The study excluded individuals with left ventricular aneurysms, previous CABG, or CABG with other valve procedures. Patients provided informed consent and follow-up was conducted monthly, with echocardiograms when needed. The median follow-up period was 11.7 months.

Results: Both male and female participants were selected in which 112 (75.67 %) of them were males and 36 (24.32 %) were females.  92.56 % and 1.34 % were operated through on and off-pump method. The mean ICU and hospital duration was 3 and 6 days. There were 6 (4.05 %) deaths during the early 30 days after the surgery followed by complications such as Inotropic support for less than 24 hours in 34 (22.97 %) patients. The LVEF (%) during pre-operative assessment was 36.82± 6.23, but after the CBAG surgery, it improved up to 42.51± 7.38. similarly, the LVDD (mm) mass was also reduced from 49.48 ±5.24 to 48.11 ±5.74 with a value of p 0.009.

Conclusion: Coronary artery bypass grafting is a safe surgical approach for patients having left ventricular dysfunction with minimum morbidity and mortality following surgery. In addition, it can also help to enhance the quality of life and left ventricular function as well.
