Abstract

The aim of this study was to assess the prognostic value of the H2 FPEF score in patients undergoing transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) and preserved left ventricular ejection fraction (EF). In this multicentre study, a total of 832 patients from two German high-volume centres, who received TAVI for severe AS and preserved EF (≥50%), were identified for calculation of the H2 FPEF score. Patients were dichotomized according to low (0-5 points; n = 570) and high (6-9 points; n = 262) H2 FPEF scores. Kaplan-Meier and Cox regression analyses were applied to assess the prognostic impact of the H2 FPEF score. We observed a decrease in stroke volume index (-2.04 mL/m2 /point) and mean transvalvular gradients (-1.14 mmHg/point) with increasing H2 FPEF score translating into a higher prevalence of paradoxical low-flow, low-gradient AS among patients with high H2 FPEF score. One year after TAVI, the rates of all-cause (low vs. high H2 FPEF score: 8.0% vs. 19.4%, P < 0.0001) and cardiovascular (CV) mortality (1.9% vs. 9.0%, P < 0.0001) as well as the rate of CV mortality or rehospitalization for congestive heart failure (6.4% vs. 23.2%, P < 0.0001) were higher in patients with high H2 FPEF score...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
