Stroke: In patients with hypertrophic cardiomyopathy, ischemic stroke is related to atrial fibrillation

Hypertrophic cardiomyopathy (HCM) patients with ischemic stroke (IS), death, heart vascular death, stroke and all major cardiovascular events in high-risk groups, including heart failure and ventricular arrhythmias leading to cardiac arrest in hospital again

HCM risk -CVA (cerebrovascular accident) score can predict IS, the use of complex weighted score score, including age, the presence or absence of atrial fibrillation, age at onset of atrial fibrillation, previous thrombotic embolism, New York Heart Association grade, left atrial size , Average wall thickness and vascular disease

A nationwide cohort in South Korea showed that the IS/systemic embolization rate of patients with atrial fibrillation combined with HCM without any non-sex CHA2DS2-VASc stroke risk factors was 4.

The predictive value of CHA2DS2-VASc score for IS is moderate (c-index≈0.

The risk of sudden cardiac death in patients with HCM can be 2011 American Heart Association / American College of Cardiology Foundation guidance will be evaluated to determine high-risk patients according to five risk factors

Nevertheless, these risk scores are partially dependent on imaging data, including ventricular wall thickness, left atrium size, left ventricular hypertrophy, and left ventricular outflow tract gradient, and may not be used to predict IS

In this way, France Centre Hospitalier Universitaire Trousseau et al.

Independent predictors of IS in HCM were older age, heart failure, atrial fibrillation, previous IS, smoking, and malnutrition (all P<0.

For HCM risk-CVA score, CHA2DS2-VASc score and French HCM score,

All c-indexes are 0.

In patients without atrial fibrillation, compared with CHA2DS2-VASc, HCM Risk-CVA score and French HCM score have obvious predictive effects (both P<0.
