Aims To characterize regional and ethnic differences in heart failure (HF) across Asia. Methods and results We prospectively studied 5276 patients with stable HF and reduced ejection fraction (≤40%) from 11 Asian regions (). Mean age was 59.6 + 13.1 years, 78.2% were men, and mean body mass index was 24.9 + 5.1 kg/m 2 . Majority (64%) of patients had two or more comorbid conditions such as hypertension (51.9%), coronary artery disease (CAD, 50.2%), or diabetes (40.4%). The prevalence of CAD was

Compared with Chinese ethnicity, Malays (adjusted odds ratio [OR] 1.97, 95% CI 1.63 -2.38) and Indians (OR 1.44, 95% CI 1.24-1.68) had higher odds of CAD, whereas Koreans (OR 0.38, 95% CI 0.29-0.50) and Japanese (OR 0.44, 95% CI 0.36-0.55) had lower odds. The prevalence of hypertension and diabetes was highest in Southeast Asians (64.2 and 49.3%, respectively) and high-income regions (59.7 and 46.2%, respectively). There was significant interaction between ethnicity and region, where the adjusted odds were 3.95 (95% CI 2.51-6.21) for hypertension and 4.91 (95% CI 3.07-7.87) for diabetes among Indians from high-vs. low-income regions; and 2.60 (95% CI 1.66 -4.06) for hypertension and 2.62 (95% CI 1.73 -3.97) for diabetes among Malays from high-vs. low-income regions. Conclusions These first prospective multi-national data from Asia highlight the significant heterogeneity among Asian patients with stable HF, and the important influence of both ethnicity and regional income level on patient characteristics.
