Do coping strategies really affect cardiovascular events? The Isfahan cohort study of adults in Eastern Mediterranean Regional Office

Psychological factors are among the most suspected indicators which may cause atherosclerosis. Coping strategies modifying psychological stress may be significantly associated with health outcomes. However, little is known about the influence of adaptive and maladaptive coping strategies on major adverse cardiovascular disease (CVD) events. The purpose of this study is to examine this idea among a sample of adults. Design: cohort study.

The Isfahan cohort study (ICS) is a longitudinal population-based, prospective study. Participants ($N=6323$ individuals aged 35 years or greater at baseline) were selected by multistage random sampling with 6-year intervals (i.e. 2001: 6323 individuals, 2007: 3296 individuals, and 2013: 1706 individuals). Adaptive and maladaptive coping strategies were evaluated by a multicomponent self-administered stress management paper-based questionnaire. All CVD events were confirmed by a blinded panel of experts and a marginal cox regression model was used to model the survival data. Adaptive coping strategies could be protective against CVD events with hazard ratios (95% confidence interval) [0.97 (0.95–0.99)] and maladaptive coping strategies seem to be a risk factor, 1.02 (1.01–1.04) in the whole population. Individuals younger than 60 showed similar results, with 0.96 (0.93–0.98) and 1.04 (1.01–1.07) for adaptive and maladaptive coping strategies, respectively. However, these findings were not replicated among seniors older than age 60.

Based on our results, coping strategies have an important role in cardiovascular events, particularly among young adults. According to the results, informing patients about adaptive stress management may promote primary prevention of CVD events.
