Background
Data comparing outcomes in heart failure (
HF
) across Asia are limited. We examined regional variation in mortality among patients with
HF
enrolled in the
ASIAN
‐HF (Asian Sudden Cardiac Death in Heart Failure) registry with separate analyses for those with reduced ejection fraction (
EF
; <40%) versus preserved EF (≥50%).
Methods and Results
The
ASIAN
‐
HF
registry is a prospective longitudinal study. Participants with symptomatic
HF
were recruited from 46 secondary care centers in 3 Asian regions: South Asia (India), Southeast Asia (Thailand, Malaysia, Philippines, Indonesia, Singapore), and Northeast Asia (South Korea, Japan, Taiwan, Hong Kong, China). Overall, 6480 patients aged >18 years with symptomatic
HF
were recruited (mean age: 61.6±13.3 years; 27% women; 81% with HF and reduced r
EF
). The primary outcome was 1‐year all‐cause mortality. Striking regional variations in baseline characteristics and outcomes were observed. Regardless of
HF
type, Southeast Asians had the highest burden of comorbidities, particularly diabetes mellitus and chronic kidney disease, despite being younger than Northeast Asian participants. One‐year, crude, all‐cause mortality for the whole population was 9.6%, higher in patients with HF and reduced
EF
(10.6%) than in those with
HF
and preserved
EF
(5.4%). One‐year, all‐cause mortality was significantly higher in Southeast Asian patients (13.0%), compared with South Asian (7.5%) and Northeast Asian patients (7.4%;
P
<0.001). Well‐known predictors of death accounted for only 44.2% of the variation in risk of mortality.
Conclusions
This first multinational prospective study shows that the outcomes in Asian patients with both HF and reduced or preserved
EF
are poor overall and worst in Southeast Asian patients. Region‐specific risk factors and gaps in guideline‐directed therapy should be addressed to potentially improve outcomes.

Current visualization techniques of complex congenital heart disease (CHD) are unable to provide comprehensive visualization of the anomalous cardiac anatomy as the medical datasets can essentially only be viewed from a flat, two-dimensional (2D) screen. Three-dimensional (3D) printing has therefore been used to replicate patient-specific hearts in 3D views based on medical imaging datasets. This technique has been shown to have a positive impact on the preoperative planning of corrective surgery, patient-doctor communication, and the learning experience of medical students. However, 3D printing is often costly, and this impedes the routine application of this technology in clinical practice. This technical note aims to investigate whether reducing 3D printing costs can have any impact on the clinical value of the 3D-printed heart models. Low-cost and a high-cost 3D-printed models based on a selected case of CHD were generated with materials of differing cost. Quantitative assessment of dimensional accuracy of the cardiac anatomy and pathology was compared between the 3D-printed models and the original cardiac computed tomography (CT) images with excellent correlation (r=0.99). Qualitative evaluation of model usefulness showed no difference between the two models in medical applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
