Type D Personality is Unrelated to Major Adverse Cardiovascular Events in Patients with Coronary Artery Disease Treated by Intracoronary Stenting

Abstract

Previous research in cardiac patients suggested that type D personality, defined as a combination of negative affectivity (NA) and social inhibition (SI), was associated with adverse outcome. The objective of this prospective study was to examine the independent prognostic value of type D in patients with coronary artery disease (CAD). A total of 465 patients completed the Type D Scale (DS14) questionnaire before undergoing stent implantation and were followed up for 5 years. In a Cox regression model adjusted for selected confounders, we found a trend towards NA for the prediction of nonfatal major adverse cardiovascular event (MACE, hazard ratio (HR) = 1.07, 95 % confidence intervals (CIs) = 0.99-1.14, p = 0.074), while, in contrast, SI was a significant and independent predictor of better outcome (HR = 0.92, 95 % CI = 0.86-0.99, p = 0.027). In a cohort of CAD patients, the type D pattern was not linked to adverse outcome, whereas SI was negatively associated with MACE.
