General Factors That Reduce Cardiovascular Risk in People With Schizophrenia: A Systematic Review.

Background: The life expectancy of individuals with schizophrenia in the United States is 20%shorter than that of the general population owing to cardiovascular disease (CVD). It is crucial to identify the factors that reduce CVD risk in these individuals. Objective: In this systematic review, we examined the factors associated with CVD in people with schizophrenia. Methods: We searched 3 electronic databases for English articles published before April 2023. Investigators assessed the factors associated with 2 cardiovascular health outcomes among people with schizophrenia: the 10-year coronary heart disease (CHD)/CVD risk and peak oxygen uptake (VO2Peak/max). Results: We retrieved 17 studies fromthe search. Investigators examined factors affecting 10-year CHD/CVD risk in 11 studies and VO2Peak/max in 6 studies among people with schizophrenia. We found that individuals who had low metabolic symptoms (ie, hypertension and hyperglycemia), did not smoke, engaged in continuous CVD risk assessments, had a shorter duration of the diagnosis and hospitalization, and were of normal weight had a lower 10-year CHD/CVD risk. Furthermore, individuals who engaged in specific physical activity had a higher VO2Peak/max. Finally, those taking antipsychotic medications had a higher 10-year CHD/CVD risk and a lower VO2Peak/max. Conclusions: The CVD risk factors observed in the general population are common among people with schizophrenia. When these risk factors are controlled, the 10-year CHD/CVD risk and VO2Peak/max of these individuals may be improved. Given the elevated CVD risk associated with antipsychoticmedications, future researchers should examinemodifying CVD risk factors to mitigate the additional risks associated with medication use in this population.
