Predictors of life-threatening events in adult patients with left ventricular noncompaction

Figure 3 Predictors of sustained ventricular tachycardia and embolic events in patients with left ventricular noncompaction. A: Kaplan-Meier curves indicating that low QRS voltage, premature ventricular contractions > 500/day, premature ventricular contractions > 1700/day, and atrioventricular block were sustained ventricular tachycardia predictive factors; B: Receiver operating characteristic curves of left ventricular end-diastolic volume [area under the curve (AUC) = 0.674, P = 0.005)], right ventricular end-diastolic diameter (AUC = 0.669, P = 0.009), left ventricular ejection fraction (AUC = 0.688, P = 0.002), and the E/A ratio (AUC = 0.707, P = 0.01) as predictors of thromboembolism in patients with left ventricular noncompaction. VT: Ventricular tachycardia; PVC: Premature ventricular contraction; AV: Atrioventricular; LVEDV: Left ventricular end diastolic volume; RV: Right ventricle; LVEF: Left ventricular ejection fraction.
