Prognostic impact of the HFA-PEFF and H2FPEF scores in patients with sick sinus syndrome

Sick sinus syndrome (SSS) frequently coexists with atrial fibrillation (AF) and may represent a clinical manifestation of atrial cardiomyopathy (AtCM). Many patients with AtCM have preserved left ventricular ejection fraction (LVEF), and heart failure with preserved ejection fraction (HFpEF) commonly overlaps wit...

Left ventricular diastolic dysfunction predicts new-onset atrial cardiomyopathy in patients with insertable cardiac monitors
