Cardiovascular and metabolic risk in outpatients with schizoaffective disorder treated with antipsychotics: Results from the CLAMORS study

AIM: To assess the coronary heart disease (CHD) risk and prevalence of the metabolic syndrome (MS) in patients with schizoaffective disorder (SD) receiving antipsychotics. METHODS: Patients meeting DSM-IV criteria for SD and receiving antipsychotic treatment were recruited in a retrospective, cross-sectional, multicenter study (the CLAMORS study). MS was defined as at least three of the following components: waist circumference greater than 102 cm (men)/greater than 88 cm (women); serum triglycerides greater or equal to 150 mg/dl; HDL cholesterol less than 40 mg/dl (men)/less than 50 mg/dl (women); blood pressure greater or equal to 130/85 mmHg; fasting blood glucose greater or equal to 110 mg/dl. The 10-year CHD risk was assessed by the Systematic coronary risk evaluation (SCORE) (cardiovascular mortality) and Framingham (any cardiovascular event) functions. Clinical severity was assessed using the PANSS and CGI-S scales. RESULTS: A total of 268 valuable patients with SD (127 men, 48.1%), 41.9±12.3 years (mean±S.D.), were analyzed. The 10-year overall cardiovascular mortality and CV-event risk were 0.8±1.6 (SCORE) and 6.5±6.8 (Framingham), respectively. A high/very high risk of any CV event (Framingham≥10%) was associated with severity [CGI-S=3-4; OR: 4.32 (1.15-16.26), P=0.03)]. MS was present in 26.5% (95%CI: 21.2-31.8) of subjects, without gender differences, but significantly associated with patient's impression of severity: CGI=3-4; OR=1.90 (0.83-4.36), and CGI=5-7; OR=3.13 (1.06-9.24), P=0<0.001, and age [OR=1.91 (1.09-3.34), P<0.024)]. CONCLUSIONS: CHD risk and MS prevalence were high among patients with SD, being MS prevalence associated with age and severity of disease.
