Kaplan Meier plots of incident heart failure admission over time between groups with pulmonary transit time ≥ 8.2 and < 8.2 among all patients (A log-rank p < 0.001), and within strata of patients with preserved left ventricular ejection fraction (B log-rank p = 0.0242) and patients with reduced left ventricular ejection fraction (C log-rank p = 0.0011)
