Trends in the utilization and reimbursement of coronary revascularization in the United States Medicare population from 2010 to 2018.

Objective: To determine utilization and reimbursement trends of coronary revascularization procedures in the US Medicare population from 2000 to 2018.

Background: US Medicare population is increasing, and coronary revascularization decreased in the 2000s.

Methods: This is a population-based, cross sectional study of US Medicare beneficiaries from 2010 to 2018.

Structural and functional cardiac profile after prolonged duration of mechanical unloading: potential implications for myocardial recovery.

Clinical and experimental studies have suggested that the duration of left ventricular assist device (LVAD) support may affect remodeling of the failing heart. We aimed to 1) characterize the changes in Ca/calmodulin-dependent protein kinase type-IIδ (CaMKIIδ), growth signaling, structural proteins, fibrosis, apoptosis, and gene expression before and after LVAD support and 2) assess whether the duration of support correlated with improvement or worsening of reverse remodeling. Left ventricular apex tissue and serum pairs were collected in patients with dilated cardiomyopathy ( n = 25, 23 men and 2 women) at LVAD implantation and after LVAD support at cardiac transplantation/LVAD explantation.
