We hypothesized that noninvasively measured right ventricular (RV) to pulmonary arterial (RV-PA) coupling would be abnormal in chronic pulmonary regurgitation (PR) even in the setting of normal RV ejection fraction, and that RV-PA coupling indices would have a better correlation with peak oxygen consumption (VO2) compared with RV systolic indices alone. ⋯ There is abnormal RV-PA coupling in chronic PR, and noninvasively measured RV-PA coupling might potentially be prognostic because of its correlation with exercise capacity.

Acute Myocardial Infarction in Severe Mental Illness: Prevalence, Clinical Outcomes, and Process of Care in U.S. Hospitalizations.
Severe mental illness (SMI) is associated with increased cardiovascular mortality. We sought to examine the prevalence, clinical outcomes, and management strategy of patients with SMI presenting with acute myocardial infarction (AMI). ⋯ Schizophrenia and ONOP are the only SMI subtypes associated with adverse clinical outcomes after AMI. However, all patients with SMI were less likely to receive invasive management for AMI, with female gender and schizophrenia diagnosis being the strongest predictors of conservative management. A multidisciplinary approach between psychiatrists and cardiologists could improve the outcomes of this high-risk population.
