Abstract

BackgroundPrior research reveals that processes and outcomes of cardiac care differ across sociodemographic strata. One potential contributing factor to such differences is the personality traits of individuals within these strata. We examined the association between risk-taking attitudes and cardiac patients- clinical and demographic characteristics, the likelihood of undergoing invasive cardiac procedures and survival.

MethodsWe studied a large inception cohort of patients who underwent cardiac catheterization between July 1998 and December 2001. Detailed clinical and demographic data were collected at time of cardiac catheterization and through a mailed survey one year post-catheterization. The survey included three general risk attitude items from the Jackson Personality Inventory. Patients- n = 6294 attitudes toward risk were categorized as risk-prone versus non-risk-prone and were assessed for associations with baseline clinical and demographic characteristics, treatment received i.e., medical therapy, coronary artery bypass graft CABG surgery, percutaneous coronary intervention PCI, and survival to December 2005.

Results2827 patients 45% were categorized as risk-prone. Having risk-prone attitudes was associated with younger age p < .001, male sex p < .001, current smoking p < .001 and higher household income p < .001. Risk-prone patients were more likely to have CABG surgery in unadjusted Odds Ratio OR = 1.21; 95% CI 1.08–1.36 and adjusted OR = 1.18; 95% CI 1.02–1.36 models, but were no more likely to have PCI or any revascularization. Having risk-prone attitudes was associated with better survival in an unadjusted survival analysis Hazard Ratio HR = 0.78 95% CI 0.66–0.93, but not in a risk-adjusted analysis HR = 0.92, 95% CI 0.77–1.10.

ConclusionThese exploratory findings suggest that patient attitudes toward risk taking may contribute to some of the documented differences in use of invasive cardiac procedures. An awareness of these associations could help healthcare providers as they counsel patients regarding cardiac care decisions.
