Abstract

Patients with schizophrenia have higher mortality and shortened life expectancy than the general population, and cardiovascular disease (CVD) accounts for up to 50% cases of early mortality in schizophrenia. We determined risk factors, particularly pathophysiological changes, for early circulatory mortality in schizophrenia. In this multi-institutional, nested, case–control study, we enrolled consecutive inpatients with schizophrenia admitted to three psychiatric hospitals in the northern Taiwan. Seventy-nine patients who died of CVD before 65 years of age were identified as cases through record linkage, and 158 controls were randomly selected in a 2:1 ratio through risk-set density sampling, after matching for age (±2 years), sex, and index admission (±3 years). Data were obtained through medical record reviews. At the time of death, the mean age of the patients was 47.5 years (standard deviation = 10.3). Conditional logistic regression revealed that the duration of antipsychotic treatment was significantly associated with a lower risk of early circulatory mortality, and leukocyte counts at index hospitalization were significantly associated with a higher risk. Systemic inflammation may be a risk factor for early circulatory mortality in schizophrenia, but antipsychotic treatment, in particular typical antipsychotic treatment, could be a protective factor.
