Systolic Heart Failure associated with Higher Mortality Among Patients Undergoing TAVR
A recent study published in the Current Problems in Cardiology have shed light on the worse outcomes in heart failure patients who undergo transcatheter aortic valve replacement (TAVR). Michael Fatuyi and team conducted the study using the National Inpatient Sample (NIS), aimed to compare clinical outcomes in patients with systolic heart failure (SHF) versus diastolic heart failure (DHF) who underwent TAVR.
The analysis included a total of 106,815 patients admitted to acute care hospitals for TAVR, with 73% of them having a secondary diagnosis of heart failure. Among the heart failure patients, 41% had SHF while 59% had DHF. The results revealed notable differences between the two groups.
Patients with SHF were found to be older, predominantly male, and more likely to be of white ethnicity. Importantly, the study showed that patients with SHF experienced worse cardiovascular outcomes compared to those with DHF. The SHF group had higher in-hospital mortality rates (1.75% vs. 1.14%), a greater incidence of cardiac arrest (1.31% vs. 0.81%), non-ST elevation myocardial infarction (2.52% vs. 1.0%), respiratory failure (10.87% vs. 8.01%), and cardiogenic shock (3.94% vs. 1.14%).
