title: Incidence of cardiac events in hypertensive men related to adaptive behavior in stressful encounters.
abstract: The Serial Color Word Test was administered at baseline to 253 hypertensive men participating in the prospective cohort study of cardiovascular diseases "Men born in 1914" in Malmö, Sweden. This test of psychological adaptation to a stressful encounter was used to investigate whether susceptibility to stress moderates the risk of a cardiac event in association with hypertension. Adaptive behavior, as measured by test performance, can be categorized in two dimensions. The regression dimension refers to linear change of time spent in the test session whereas the variability dimension refers to nonlinear change. Both dimensions consist of four different patterns. At follow-up (mean time = 8.2 +/- 3.5 years), the risk of a cardiac event varied between men with different adaptive patterns. One pattern, the Cumulative-Dissociative pattern of the variability dimension, characterized by a discontinuous and fluctuating time-consumption, was associated to an almost three-fold risk of a cardiac event during follow-up (relative risk [RR], 2.99; 95% confidence interval [CI], 1.33 - 6.70, p = .010) after adjustment for medical-, socioeconomic-, and lifestyle-related factors. No association existed between adaptive patterns and overall mortality.
