Also, both albuminuria determined by urinary albumin‐to‐creatinine ratio (UACR), and Kansas City Cardiomyopathy Questionnaire overall summary score (KCCQ‐OSS) were highly significant independent predictors (each p < 0.0001), but they were excluded from our primary model because these variables are not readily available for clinical use, and also UACR was not available in our validation cohort.
