Increased perivascular fibrosis and pro-fibrotic cellular transition in intramyocardial blood vessels in myocardial infarction patients.

Background And Objectives: Structural and functional changes in the intramyocardial microcirculation increase the risk of myocardial infarction (MI). This study investigated intramyocardial perivascular fibrosis and pro-fibrotic cellular transitions in deceased acute and subacute MI patients to explore their involvement in the pathogenesis of MI.

Methods: Left ventricular tissue (LV) was obtained from the infarction area of autopsied patients with acute-phase MI (3-6 h;  = 24), subacute-phase MI (5-14 days;  = 12), and noninfarcted controls ( = 14).

Characteristics of patients in inpatient psychiatry during the COVID-19 pandemic.

To date, there have been limited publications examining the characteristics of psychiatric patients with COVID-19 in an inpatient setting. In this retrospective cohort review, we attempted to categorize the differences between patients admitted to the COVID unit versus the non-COVID unit using data from a community hospital located on Long Island, NY. We found that patients admitted to the COVID-19 unit had on average longer lengths of stay, were more likely to belong to non-white racial groups, and were less likely to be smokers.
