Influence of smoking status and chronic obstructive lung disease on the incidence of appropriate ICD interventions in a collective of ICD recipients with structural heart disease

Background: Chroncic obstructive lung disease (COPD) represents a severe illness which is often associated with other grave comorbidities. This study was initiated to explore the influence of the presence of COPD on the incidence of appropriate ICD interventions. Methods: This trial included 349 patients with structural heart disease, either coronary artery disease or non-ischemic cardiomyopathy equipped with an implantable cardioverter defibrillator (ICD).
