Objective: To investigate the prevalence of statin-untreated schizophrenic patients needing treatment according to the 2013 American College of Cardiology and the American Heart Association (ACC/AHA) guidelines and to compare the performance of these guidelines to the 2004 National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP-III) recommendations.
Methods: A cross-sectional study was conducted using medical charts, patient inverventions, and various anthropometric measures between April 2016 and July 2016 at the Psychiatric Hospital of the Cross enrolled 329 patients with schizophrenia (DSM-5 criteria) to determine dyslipidemia and risk for atherosclerotic cardiovascular disease (ASCVD).
Results: Of the patients, 81.25% (130 patients of 160) who need a statin therapy according to the ACC/AHA guidelines would not need a therapy according to the NCEP ATP-III, while only 9.1% of the total population met the criteria for both guidelines concomitantly. A significant difference in favor of the ACC/AHA guideline was found between the 2 guidelines (P < .001). Among the 130 patients who need a statin treatment, 124 (95.4%) had ASCVD ≥ 7.5%, 13 patients (10%) had diabetes, 1 patient (0.8%) had clinical cardiovascular disease (CVD), and none had low-density lipoprotein > 190 mg/dL.
Conclusions: Although our results showed the superiority of the 2013 ACC/AHA guidelines over the 2004 NCEP guidelines for detecting undiagnosed dyslipidemia, the absolute benefit or risk of a statin therapy according to these guideline recommendations remains unclear in this population of schizophrenic patients because the actual occurrence of CVD or statin-related adverse events was not investigated in this study. Further studies are needed to evaluate the reduction in CVD by a statin treatment according to both guidelines and thus compare the actual benefit of statin assignment in schizophrenic patients.
