Aim: To study prevalence of left ventricular diastolic and systolic dysfunction in patients with COPD.

Patients and methods: 100 patients with COPD referred for cardiac evaluation to our department. Apart from routine

investigation 2D, M mode, Doppler and DTI were done. LV diastolic dysfunction was assessed by mitral inflow Doppler. LV systolic

function was assessed by LV EF and Mitral annular peak S wave velocity.

Results: 84% of them had pulmonary hypertension. Out of these 54% of them have mild, 26% moderate and 4% severe PHT.

70% of COPD patients had diastolic dysfunction in our study. Our study reports that 10% of the COPD patients had LV systolic

dysfunction (EF< 50%).

CONCLUSION: LV systolic dysfunction is directly proportional to severity of COPD. Smoking index and duration of smoking are

positively correlated with development of LVSD. Our study reports that 44.4% of severe COPD patients have LVSD. So we

recommend routine echocardiography for all severe COPD patients.
