Abstract

To determine trends and impact on outcomes of acute myocardial infarction (AMI) in patients with pre-existing psychosis. While post-AMI psychosis has been extensively studied, contemporary studies including temporal trends on impact of pre-AMI Psychosis on AMI and post-AMI outcomes are lacking. We used Nationwide Inpatient Sample (NIS) from Healthcare Cost and Utilization Project(HCUP) from 2002 to 2012. We identified AMI and psychosis as primary and secondary diagnosis respectively using validated International Classification of Diseases, 9th Revision, and Clinical Modification (ICD9CM) codes, and Cochrane-Armitage trend test and multivariate regression to generate adjusted odds ratios (aOR). We analyzed total of 7,174,274 AMI hospital admissions from 2002 to 2012 of which 1.77% had psychosis. Proportion of hospitalizations with psychosis increased from 6.94% to 11.85% (P-trend<0.001). Utilization of percutaneous coronary intervention (PCI) was lower in patients with psychosis (29.98% vs. 40.36%, P<0.001). Utilization of coronary artery bypass grafting (CABG) was lower in patients with psychosis (8.01% vs. 9.18%, P<0.001). In-hospital mortality was significantly lower in patients with psychosis (aOR 0.677; 95% CI 0.630–0.727; P<0.001) but discharge to specialty care higher (aOR 1.870; 95%CI 1.786–1.958; P<0.001). In addition, median length of hospitalization (3.77 vs. 2.90days; P<0.001) was higher in hospitalizations with psychosis. Our study displayed increasing proportion of patients with psychosis admitted due to AMI in last decade with lower mortality but higher morbidity post-infarction, and significantly less utilization of PCI and CABG. There was also increased length of stay patients with MDD. There is need to explore reasons behind this disparity in outcomes and PCI and CABG utilization to improve post-AMI outcomes in this vulnerable population.
