Background
Previous study has demonstrated that the presence of moderate and severe degree of tricuspid regurgitation (TR) is associated with adverse outcome in patients with heart failure with reduced ejection fraction. However, little is known about the prevalence and prognostic value of TR in patients with stage A, B and C heart failure with preserved ejection fraction (HFpEF).
Method(s)
A total of 2882 patients with stage A (n=904), B (n=1305) and C (n=673) HFpEF from 2013 to 2017 were enrolled. Detailed transthoracic echocardiogram was performed and the severity of TR was graded according to the latest recommendation. Patients were prospectively follow up at our heart failure clinic.
Result(s)
The age of the study population was 65 and 47% were male. Hypertension was presence in 58% and diabetes in 33% and the mean left ventricular ejection fraction was 62%. The prevalence of moderate and severe TR increased from stage A to C HF (4.2%, 5.9% and 16.5%, respectively, P<0.01). Kaplan-Meier curve revealed that the presence of moderate and severe degree of TR was associated with all-cause mortality and heart failure hospitalization (Log-rank test P<0.01)(Figure). Multivariable analysis demonstrated that moderate (hazard ratio=1.57, P<0.01) and severe TR (hazard ratio=2.35, P<0.01) was associated with mortality and heart failure hospitalization after adjusting for age, gender, EF, atrial fibrillation and HF stage.
Conclusion(s)
The presence of moderate and severe TR is not uncommon in patients with stage A, B and C HFpEF. Importantly, moderate and severe TR was independently associated with mortality and heart failure hospitalization.

ECHO ASIA is organized by Asian-Pacific Association of Echocardiography (AAE). The meeting combines the basic echocardiography training curriculum and the state-of-the-art lectures/scientific sessions provided by international as well as Asian-Pacific experts. The meeting is a unique forum where scientists from many countries in the Asian-Pacific region who are involved in the field of Doppler echocardiography gather together to exchange knowledge and skills. Various internationally distinguished faculties consent to present their findings and reveal their clinical experiences in ECHO ASIA.
