This study evaluated body mass index, body surface area, subcutaneous fat tissue, and coronary atherosclerosis by autopsy reports for people with schizophrenia who were deceased to evaluate the presence of cardiac atherosclerosis and its association with body weight. Included in the study were autopsy reports for 134 people with schizophrenia and 134 matched normal subjects who had died between January 1990 and December 2000 and whose family had donated brain tissue to Maryland Brain Collection. Cause of death due to cardiovascular disease was observed for 45.7% of people with schizophrenia and 42.3% of the control group (P = NS). Body weight, body mass index, body surface area, and subcutaneous fat were not significantly different between the 2 groups; however, a larger proportion of the schizophrenia group had high (33.3%) and low (20.9%) percentile body weight compared with controls (27.7% vs 10.0%). People with schizophrenia who were underweight had higher rates of cardiac death than the controls (37.7% vs 13%) (chi(2) = 5.79, P = .01); however, no difference was noted in the number of coronary arteries occluded. Twenty-three (48.9%) of 47 of the controls with abnormally high subcutaneous fat showed cardiac atherosclerosis, whereas only 15 (33.3%) of 45 of the schizophrenia group with abnormally high subcutaneous fat had atherosclerosis (P = NS). Overall, the percentage of deaths due to cardiovascular disease was not higher in people with schizophrenia; however, in normal controls, cardiovascular disease appears to be related more to weight than in people with schizophrenia. This may be related to intrinsic metabolic differences associated with schizophrenia, lifestyle differences, or effects of antipsychotic medications. Nonetheless, our study suggests that efforts for the prevention of coronary atherosclerosis in schizophrenia patients should go beyond weight control to target multiple risk factors such as smoking, dyslipidemia, and cardiac side effect of antipsychotic medications.
