Patients with<unk><unk>  are at risk of arrhythmias and sudden death.  Abnormal filling of the left atrium may result in the left atrial dilation which may predispose the patient to atrial fibrillation.  The presence of myocardial disarray and myocardial ischemia (due to microvascular dysfunction and episodes of reduced cardiac output) may predispose the patient to ventricular tachycardia, ventricular fibrillation, and sudden cardiac death.
