The Biomarkers for Acute Myocardial Infarction and Heart Failure.

ABSTRACT: The use of a large number of cardiovascular biomarkers, meant to complement the use of the electrocardiogram, echocardiography cardiac imaging, and clinical symptom assessment, has become a routine in clinical diagnosis, differential diagnosis, risk stratification, and prognosis and guides the management of patients with suspected cardiovascular diseases. There is a broad consensus that cardiac troponin and natriuretic peptides are the preferred biomarkers in clinical practice for the diagnosis of the acute coronary syndrome and heart failure, respectively, while the roles and possible clinical applications of several other potential biomarkers are still under study. This review mainly focuses on the recent studies of the roles and clinical applications of troponin and natriuretic peptides, which seem to be the best-validated markers in distinguishing and predicting the future cardiac events of patients with suspected cardiovascular diseases. Additionally, the review briefly discusses some of the large number of potential markers that may play a more prominent role in the future.

Project description:Importance:Hospitals in the United States have been subject to mandatory public reporting of mortality rates for acute myocardial infarction (AMI) and heart failure (HF) since 2007 and to value-based payment programs for these conditions since 2011. However, whether hospitals with initially poor baseline performance have improved relative to other hospitals under these programs, and whether patterns of improvement differ by condition, is unknown. Understanding trends within public reporting and value-based payment can inform future efforts in these areas. Objective:To examine patterns in 30-day mortality from AMI and HF and determine whether they differ for baseline poor performers (worst quartile in 2009 and 2010 in public reporting, prior to value-based payment) compared with other hospitals. Design, Setting, and Participants:Retrospective cross-sectional study at US acute care hospitals from 2009 to 2015 that included 2751 and 3796 hospitals with publicly reported mortality data for AMI and HF, respectively. Exposures:Public reporting and value-based purchasing. Main Outcomes and Measures:Hospital-level risk-adjusted 30-day mortality rates. Results:We identified 422 and 600 baseline poor-performing hospitals for AMI and HF, respectively. Baseline poor performers for AMI were more often public and for-profit and less often teaching hospitals. Baseline poor performers for HF were less often large hospitals. For AMI, 30-day mortality among baseline poor performers was higher at baseline but improved more over time compared with other hospitals (18.6% in 2009 to 14.6% in 2015; -0.74% per year; P?<?.001 vs 15.7% in 2009 to 14.0% in 2015; -0.26% per year; P?<?.001; P for interaction <.001). In contrast, for HF, baseline poor performers improved over time (13.5%-13.0%; -0.12% per year; P?<?.001), but mean mortality among all other HF hospitals increased during the study period (10.9%-12.0%; 0.17% per year; P?<?.001; P for interaction, <.001). Conclusions and Relevance:Despite being subject to identical policy pressures, mortality trends for AMI and HF differed markedly between 2009 and 2015.
