Abstract

Aortic valve disease (AVD) has similarities to atherosclerosis in the case of aortic stenosis. The important role of platelet in the pathogenesis of atherosclerosis is known. The goal of this study is to evaluate whether platelet disorders play any role in aortic valve disease. We used patients with idiopathic thrombocytopenic purpura (ITP) for this study. We evaluated any association between ITP and AVD using a large inpatient database. The International Classification of Diseases, Ninth Revision, and Clinical Modification (ICD-9-CM) codes for ITP and AVD from the Nationwide Inpatient Sample (NIS) database were used for this study. Uni- and multivariate analyses were performed on data from 2002 to 2011 to evaluate any association between ITP and AVD. In the 2002 database, AVD was present in 1.73% of ITP patients versus 1.12% in the control population (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.34–1.81; p < 0.001). In the 2011 database, AVD was present in 1.96% of ITP patients versus 1.33% in the control population (OR, 1.48; 95% CI, 1.30–1.68; p < 0.001). ITP remained independently associated with AVD following a multivariate logistic regression analysis adjusting for age, gender, diabetes mellitus, hypertension, and hyperlipidemia in 2002 (OR, 1.35; 95% CI, 1.16–1.57; p < 0.001) with a trend of this association in 2011 (OR, 1.12; 95% CI, 0.98–1.27; p = 0.096). ITP was strongly associated with AVD over the 10-year period analyzed in a large inpatient database. The reason for this association is not known warranting further investigations.
