[Cardiac troponins - biomarkers for cardiovascular disease in chronic obstructive pulmonary disease].

Chronic obstructive pulmonary disease (COPD) and cardiovascular disease (CVD) are frequently associated and share common risk factors, pathophysiological processes, symptoms and clinical signs. Ischemic heart disease, heart failure, pulmonary hypertension and atrial fibrillation are common comorbidities of COPD. COPD has been described as an independent risk factor for CVD. Cardiac troponin elevation, indicating myocardial injury, is associated with both the stable state of COPD and acute exacerbation of COPD. The mechanisms of elevated troponin levels in these conditions are multiple and not fully understood. The aim of this article is to discuss the association between COPD, CVD and cardiac troponins.
