Prevalence And Risk Factors For Coronary Artery Disease In Patients Of Chronic Obstructive Pulmonary Disease.

[摘要] CAD and COPD are related closely, as they share common causative risk factors. COPD relatedsystemic inflammation adds to the CAD risk. CAD may therefore be common in COPD but often silent. To studythe prevalence of CAD in COPD and study the risk factors. This was a cross sectional study which was carriedout using a semi-structured questionnaire along with a complete cardiac assessment to evaluate for thepresence of associated CAD in 200 patients of COPD diagnosed by GOLD criteria. 89/200 (44.5%) had abnormalECG/2D echocardiogram suggesting CAD. 17 /89 patients who underwent coronary angiography had significantblocks confirming the diagnosis of CAD. Out of 200 cases, 87/200 (43.5%) were tobacco smokers and 113/200(56.5%) had biomass fuel exposure. Incidence of CAD correlated with smoking index as well as severity ofairflow obstruction (p-value <0.05). Risk of CAD is high in COPD and seems to increase with COPD severity andsmoking index.
