Aims: A compromised tricuspid annular plane systolic excursion (TAPSE) is associated with worse survival in patients with chronic heart failure with reduced ejection fraction (HFrEF). However, it is not known whether a reversible abnormal TAPSE at follow-up predicts survival. Our aim was to evaluate whether a reversible abnormal TAPSE is associated with a better survival in patients with chronic HFrEF. Methods and results: A complete echocardiography was performed in 706 patients with chronic HFrEF (LVEF ≤45%) at baseline and after 6 ± 3 months. Right ventricular (RV) systolic function was evaluated using TAPSE. The study endpoint was all-cause mortality. At baseline, TAPSE was severely reduced (≤14 mm) in 89 (13%) patients, and slightly reduced (>14 but <18 mm) in 157 (22%) patients. During a median follow-up of 40 months, 152 patients reached the endpoint. The event rate (per 100 patients/year) was lower in patients with persistently normal TAPSE (≥18 mm, n = 393) [3.3%, 95% confidence interval (CI) 2.5–4.3], and in those with reversible TAPSE (n = 120) (4.6%, 95% CI 3.1–7.0), compared with patients with worsening TAPSE (n = 90) (11.9%, 95% CI 8.7–16.3), and those with persistently reduced TAPSE (n = 103) (12.6%, 95% CI 9.3–17.1; log-rank 69.4, P < 0.0001). A reversible abnormal TAPSE was associated with improved survival at multivariable Cox regression analysis (hazard ratio 0.48, 95% CI 0.29–0.79, P = 0.004). Conclusions: Patients with chronic HFrEF who have abnormal TAPSE at baseline but reverse their dysfunction during follow-up have better survival than patients with either worsened TAPSE or persistently abnormal TAPSE, and similar to that of patients with persistently normal TAPSE. © 2016 The Authors.

Abstract

Aims: A compromised tricuspid annular plane systolic excursion (TAPSE) is associated with worse survival in patients with chronic heart failure with reduced ejection fraction (HFrEF). However, it is not known whether a reversible abnormal TAPSE at follow-up predicts survival. Our aim was to evaluate whether a reversible abnormal TAPSE is associated with a better survival in patients with chronic HFrEF. Methods and results: A complete echocardiography was performed in 706 patients with chronic HFrEF (LVEF ≤45%) at baseline and after 6 ± 3 months. Right ventricular (RV) systolic function was evaluated using TAPSE. The study endpoint was all-cause mortality. At baseline, TAPSE was severely reduced (≤14 mm) in 89 (13%) patients, and slightly reduced (>14 but <18 mm) in 157 (22%) patients. During a median follow-up of 40 months, 152 patients reached the endpoint. The event rate (per 100 patients/year) was lower in patients with persistently normal TAPSE (≥18 mm, n = 393) [3.3%, 95% confidence interval (CI) 2.5–4.3], and in those with reversible TAPSE (n = 120) (4.6%, 95% CI 3.1–7.0), compared with patients with worsening TAPSE (n = 90) (11.9%, 95% CI 8.7–16.3), and those with persistently reduced TAPSE (n = 103) (12.6%, 95% CI 9.3–17.1; log-rank 69.4, P < 0.0001). A reversible abnormal TAPSE was associated with improved survival at multivariable Cox regression analysis (hazard ratio 0.48, 95% CI 0.29–0.79, P = 0.004). Conclusions: Patients with chronic HFrEF who have abnormal TAPSE at baseline but reverse their dysfunction during follow-up have better survival than patients with either worsened TAPSE or persistently abnormal TAPSE, and similar to that of patients with persistently normal TAPSE. © 2016 The Authors.
