Key result
In a patient with hypertrophic cardiomyopathy and preserved ejection fraction, a markedly impaired global longitudinal strain of -6.2% guided the decision to initiate anticoagulation.
Why the study?
The authors intended to demonstrate the clinical utility of global longitudinal strain in patients with hypertrophic cardiomyopathy and preserved ejection fraction.

Global longitudinal strain may serve as a useful prognostic tool to detect subtle left ventricular dysfunction and guide anticoagulation in patients with hypertrophic cardiomyopathy and atrial fibrillation who have preserved ejection fraction.
Battel et al. (2022) conducted a case report in Hypertrophic cardiomyopathy with preserved left ventricular ejection fraction (n=1). Global longitudinal strain (GLS) measurement was evaluated. In a patient with hypertrophic cardiomyopathy and preserved ejection fraction, a markedly impaired global longitudinal strain of -6.2% guided the decision to initiate anticoagulation.
