Abstract
Pulmonary hypertension was the major cardiovascular complication of COPD , the chronic hypoxia of COPD is responsible for the development of pulmonary hypertension .24 percent of the total cases had pulmonary hypertension. The need for life long oxygen therapy was reemphasized in this study by establishing that nine patients had p wave amplitude summation in 2, 3, av F of more than 9 mm. The study also established that the best non invasive way to detect raised pulmonary arterial pressure was detecting tricuspid regurgitation by echocardiogram. Males Predominantly had Emphysema female had predominantly Chronic Bronchitis with corpulmonale 9 /50 had 2+3+avF *P* wave amplitude > 9m as this the one of the indication for **Long Term Oxygen Therapy as per The American Thoracic Society**. Urbanization , pollution of air, textile industry, dye industry, cotton industry, farming activities, smoking are major triggers for copd more over the complications of copd like pulmonary hypertension corpulmonale were better found by ecg and echocardiogram. The use of ecg was in detecting the patients who need o2 Therapy [if the combined 2+3+avF P wave amplitude more than 9 mm]. the evidence of pulmonary hypertension right Ventricular hypertrophy were, detected well,. Normally it is difficult to Estimate pulmonary arterial pressure invasively via catheter but Easy to measure it indirectly if we measure it by detecting Tricuspid regurgitation nonivasively by echocardiogram. 18% patients had concomitant CAHD, this observation is important, because systemic inflammation plays enhanced role in atherosclerosis, diabetes. [TNF alpha is increased in COPD, patients]. Finally the study by analyzing COPD patients with clinical arameters, ECG, ECHOCARDIOGRAM, concluded that pulmonary hypertension was the most common cardiovascular complication leading to cor pulmonale, and emphysema was more common in smokers, bronchitis was more common in females , the prevalence of COPD was more in urban areas due o pollution of air by automobiles. The textile based industries were mainly responsible for the increased prevalence of COPD.
