The real world of stroke incidence in patients with hypertrophic cardiomyopathy

We have read a paper with great interest written by Fumagalli and colleagues concerning “the incidence of stroke in patients with hypertrophic cardiomyopathy (HCM) among different heart rhythm” [ [1] Fumagalli C. et al. Incidence of stroke in patients with hypertrophic cardiomyopathy in stable sinus rhythm during long-term monitoring. Int. J. Cardiol. 2023; 381: 70-75 Abstract Full Text Full Text PDF PubMed Scopus (1) Google Scholar ]. In this paper, the authors found that stroke rates in HCM patients no prior history of atrial fibrillation (AF), stroke rates were similar in those with de novo AF or stable sinus rate (SR). And they further observed that severe left atrium dilatation was a powerful risk factor, irrespective of AF. The results provided evidence for the anticoagulation strategies to prevent stroke in patients with HCM.
