Patient cohort description. Phenotyping algorithm to define HF cohorts. HF patients were selected with hospital visits over a time span of 13 years at the University Hospital Heidelberg. We defined a general HF cohort by selecting patients with either two or more HF relevant ICD-10 codes or one HF relevant ICD-10 code and one additional HF relevant clinical characteristic, yielding 29,047 HF patients. Based on LvEF, we subclassified HF patients to HFrEF, HFmrEF, or HFpEF.
