Prevalence and incidence of cognitive impairment and dementia in heart failure - A systematic review, meta-analysis and meta-regression.

Introduction: The burden of cognitive impairment in heart failure (HF) patients is significant and leads to longer hospital stay, higher readmission rates, and increased mortality. This review seeks to synthesize the available studies to determine the prevalence and incidence of cognitive impairment and dementia in HF patients.

Methods: PubMed, Embase, PsychoINFO, and Cochrane databases were systematically searched from their inception through to May 3, 2021.

Prevalence and outcomes of concomitant cardiac amyloidosis and aortic stenosis: A systematic review and meta-analysis.

Objective: Cardiac amyloidosis (CA) is an increasingly recognised condition in patients with aortic stenosis (AS). However, there is a large variation in the reported prevalence figures, due to differences in populations and diagnostic methods. We aimed to investigate the prevalence, risk factors and outcomes of concomitant CA and AS.
