Abstract

To validate the utility of CHA2DS2-VASc score to predict the annual risk of stroke in patients admitted with acute heart failure, comparing those with preserved ejection fraction (HF-presEF) and reduced ejection fraction (HF-redEF). We investigated 2922 patients with known atrial fibrillation who were admitted to the Sheba Medical Center for acute decompensated heart failure (HF). Anticoagulation therapy was prescribed based on CHA2DS2-VASc score or physician's discretion. Subjects were divided into four pre-specified groups based on HF type and median CHA2DS2-VASc score: HF-presEF with CHA2DS2-VASc <5(N = 731), HF-presEF with CHA2DS2-VASc ≥5 (N = 1102), HF-redEF with CHA2DS2-VASc <5 (N = 563), and HF-redEF with CHADS2-VASc ≥5 (N = 526). The primary endpoint was an ischaemic stroke at 1 year. Mean age of the study population was 79 ± 11 years, of whom more than half were women. The median CHA2DS2-VASc score for the entire study population was 5.0 (interquartile range 25-75%: 4-6). Stroke rate for the entire study population was 6.6%. Multivariate Cox regression proportional hazards regression analysis revealed that in both HF-redEF and HF-presEF patients, each one-point increment in CHA2DS2-VASc was associated with a correspond...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.
