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%).

Additionally, the study found that patients with SHF required longer hospital stays (5.1 days vs. 3.9 days) and incurred higher average hospital costs ($52,901 vs. $48,070) compared to those with DHF. These findings highlight the increased burden on healthcare resources associated with treating SHF patients undergoing TAVR.

The implications of this research suggest that distinguishing between systolic and diastolic heart failure is essential for accurate prognosis and treatment planning in patients undergoing TAVR. Recognizing the distinct outcomes and resource utilization patterns can aid healthcare providers in delivering personalized care to heart failure patients undergoing this procedure.

The researchers emphasized the importance of further research and potential interventions to improve outcomes in patients with systolic heart failure. These findings contribute to a better understanding of the nuances within the heart failure population and can guide healthcare professionals in optimizing care strategies for TAVR patients.
