Outcomes of Intracoronary Brachytherapy for In-Stent Restenosis.

Because of limited alternative options, intracoronary brachytherapy (ICBT) continues to be used for treating in-stent restenosis (ISR). We examined the indications, characteristics, and outcomes of ICBT in consecutive patients who underwent ICBT for ISR between January 2014 and December 2023 at a tertiary care center. During the study period 343 patients underwent ICBT of 502 lesions.

The changing landscape of cardiac co-morbidities and in-hospital cardiac complications mediating Covid-19 mortality between 2020 and 2021.

Background: Cardiac co-morbidities and in-hospital cardiac complications significantly contribute to COVID-19 mortality. However, their influence on mortality between 2021 and 2020 may differ due to the availability of vaccines, different viral strains, and therapeutic advancements.

Methods: We performed a retrospective chart review and individual patient analysis of all COVID-19 associated in-patient deaths in 2020 ( = 346) and 2021( = 527) in a large Minneapolis health system.
