Frequency of obstructive coronary artery disease in patients undergoing valvular heart disease surgery.

Objectives: To determine the frequency of obstructive coronary artery disease in patients undergoing valvular heart disease surgery. Study Design: Cross-sectional study. Setting: Department of Cardiology, Faisalabad Institute of Cardiology, Faisalabad. Period: Six months, from 02 February, 2017 to 01 August, 2017. Material & Methods: After taking approval from hospital ethical committee, patients coming through outpatient department who fulfilled the inclusion criteria were enrolled and informed consent was taken from them. History of smoking, diabetes mellitus, renal dysfunction, dyslipidemia, hypertension and family history of coronary artery disease was assessed. Coronary angiography was performed by senior consultant interventional cardiologist for assessing obstructive coronary artery disease as per operational definition. All the information was collected on prespecified Performa. Results: In this study, out of 140 cases of valvular heart disease (VHD), 47.14%(n=66) were between 30-50 years of age whereas 52.86%(n=74) were between 51-70 years of age, mean ±sd was calculated as 51.71+9.09 years, 57.14%(n=80) were male while 42.86%(n=60) were female, frequency of obstructive coronary artery disease in patients undergoing valvular heart surgery was recorded as 29.3% (n=41) whereas 70.7% (n=99) had no such finding. Conclusion: The frequency of obstructive coronary artery disease was (29.3%) in patients undergoing valvular heart disease surgery. However, coronary artery disease was less frequent in rheumatic as compared to degenerative heart valve disease.
