HD = heart disease; PTSD = posttraumatic stress disorder; BMI = body mass index; HR = hazard ratio.
*
Two-sided χ2 test, df = 1.
a
HD mortality included myocardial infarction, chronic ischemic HD, atherosclerotic HD, heart failure, and hypertensive HD.
b
For the PTSD measures used, the bivariate Cox regression results for HD mortality by PTSD-positive status were: D-PTSD = hazard ratio (HR) of 2.23, p = .031; K-PTSD = HR of 2.39, p = .033.
Note: Table 2 percents based on percents for column variable shown. For example, of those with HD at follow-up in Table 2, 15.4% had D-PTSD at baseline.
