Incidence of Right Ventricular Dysfunction In Patients of LV Dysfunction with Coronary Artery Disease and Short Term Outcome

Abstract

Objective: To determine the incidence of RV dysfunction in patients of LV dysfunction with coronary artery disease and short term outcome.

Methodology: This prospective study was carried out on 168 patients of LV dysfunction with coronary artery disease in the Echocardiography Unit of the departments of Cardiology, Liaquat University Hospital, Hyderabad from 1st October 2017 to 31st October 2018 and followed for three months. All patients with documented CAD were included. RV evaluation was performed on echocardiography through visual evaluation of RV function, RV region measured in four-chamber perspective and RV duration in a lengthy parasternal perspective. RV dysfunction was characterized as TAPSE of less than 1.2 cm. (RV ejection fraction < 35%). All the data was calculated on SPSS version 16.0.

Results:  A total of 168 patients were included in this study based on inclusion criteria, out of the 92(54.7%) were male and 76 (45.3%) were female. The mean ± SD (range) was 52.36 ± 10.44 (30 to 60 years). The mean ± SD of RV ejection fraction was 40.73  ± 8.23% (range 25 to 52). The incidence of RV dysfunction was present in 30(17.8%) patients.

Conclusion: In patients with LV dysfunction with coronary disease, in our pateints. It is an independent predictor of death and the development of HF in patients with LV dysfunction
