Rehospitalizations after acute myocardial infarction for unplanned coronary revascularization and unstable angina (UA) are common. However, despite the inclusion of these events in composite end points of many clinical trials, their association with health status has not been studied.We included 3283 patients with acute myocardial infarction enrolled in a prospective, 24-center US study who had rehospitalizations independently classified by experienced cardiologists. Health status was assessed using Seattle Angina Questionnaire and EuroQol-5D Visual Analog Scale. In the propensity-matched cohorts, 1-year health status was compared between those who did and did not experience rehospitalization for UA or revascularization using a hierarchical linear model. Overall, mean age was 59 years, 33% were women, and 70% were white. Rehospitalization rates for UA and unplanned revascularization at 1 year were 4.3% and 4.7%. One-year Seattle Angina Questionnaire summary scores were worse in patients with rehospitalizations for UA (mean difference, -10.1; 95% confidence interval, -12.4 to -7.9) and unplanned revascularization (mean difference, -5.7; 95% confidence interval, -8.8 to -2.5) when compared with patients without such rehospitalizations. Similarly, EuroQol-5D Visual Analog Scale scores were worse among patients with such readmissions. Individual Seattle Angina Questionnaire domains indicated worse 1-year angina and quality of life outcomes among patients rehospitalized for UA or unplanned revascularization.Within the first year after acute myocardial infarction, rehospitalizations for UA and unplanned revascularization are associated with worse health status. These findings highlight the impact of such events from a patient's perspective, beyond their economic impact and support the use of UA and unplanned revascularization as elements of composite end points.

Dating violence is a serious public health concern both per se and because victimization in the young adult years can be a precursor to more severe incidents of domestic violence later, in the context of cohabitation or marriage. To date, no quantitative studies have examined dating violence among college students in Chile. To address this gap, a survey on this topic was administered to students at a major public university. The present analyses focused on the female sample (n=441). Generalized ordered logit models were used to assess factors associated with physical victimization since age 14, considering three categories: no victimization, victimization with no injury, and victimization with injury. Approximately 21% of subjects reported one or more incidents of physical dating violence not involving injury since age 14, and another 5.0% reported at least one incident resulting in injury during this time period. The corresponding figures for the past 12 months were 12.9% and 2.4%, respectively. Childhood sexual abuse and witnessing domestic violence as a child were associated with substantially elevated odds of physical victimization later in life. Low parental education was also associated with higher vulnerability, in part because of its linkage with childhood experiences with aggression. Protective factors included maternal employment and religious service participation at age 14, residence in the parental home during the college years, and never having had sexual intercourse. The findings suggest that it would be desirable to develop public health initiatives to prevent and respond to this form of violence among Chilean college students.
