Obstructive sleep apnoea (OSA) is the commonest form of sleep disordered breathing. Cardiovascular morbidity and mortality are serious complications of OSA. This study was done to evaluate cardiac parameters by Doppler Echocardiography (DE) in patients with OSA in central India. Fifty patients with OSA, diagnosed on full night polysomnography, were recruited into the study. DE was done following standard guidelines. Eighty eight percent of the patients with OSA had normal DE. Thirty one patients were hypertensive. A mild increase in PAP was noted in 6 (12%) patients. Mild LV dysfunction was present in 4 patients. Six patients had diastolic dysfunction. Abnormal DE parameters were present in patients with severe OSA only. A binary logistic regression analysis showed that DE changes were seen in OSA patients with hypertension. Majority of the patients with OSA of all severity had normal DE. Severe OSA, in some cases, was associated with abnormal DE. Abnormal DE in these patients was related to hypertension than to OSA.
