From: Sudden cardiac death in heart failure with preserved ejection fraction: an updated review
Four pillars of sudden cardiac death in HFpEF and relevant mechanisms. Dash lines mean need of more literature to elucidate. Abbreviation: HFpEF (heart failure with preserved ejection fraction); CMR (cardiac magnetic resonance); LGE (late gadolinium enhancement); HCM (hypertrophic cardiomyopathy); ARVC (arrhythmogenic right ventricular cardiomyopathy); GWAS (genome-wide association studies), VT (ventricular tachycardia); VF (ventricular fibrillation); ICD (implantable cardioverter-defibrillator); PEA (pulseless electric activity)
