FREQUENCY OF UNDIAGNOSED ISCHEMIC HEART DISEASE IN PATIENTS ADMITTED WITH ACUTE EXACERBATION OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE
Objective: To determine the frequency of undiagnosed ischemic heart disease inpatients admitted with acute exacerbation of COPD (AECOPD).
Methodology: This cross sectional study was done from 1 January to 31December 2015 at Pulmonolgy Department of Khyber Teaching HospitalPeshawar on patients admitted with acute exacerbation of COPD.

Data entered onSPSS version 19 and analyzed.
Results: A total of 412 patients were admitted with the diagnosis of AECOPD.Mean age of the study sample was 61.6±12.5 years, with 41% males.Frequency of undiagnosed ischemic heart disease was found to be 18%. Amongthem 47% had unstable angina, 23% had myocardial infarction and 30% hadischemic cardiomyopathy on echocardiography.
