Background: Heart failure with preserved or mildly reduced ejection fraction (HFpEF/HFmrEF) has differences in therapy and development when compared with HF with reduced EF (HFrEF). We aimed to describe the clinical characteristics and all-cause mortality of patients with HFpEF/HFmrEF compared to those with HFrEF from the Colombian Heart Failure Registry (RECOLFACA).
Methods: RECOLFACA included Colombian adult patients with ambulatory HF recruited from 2017 to 2019. All-cause mortality was our main outcome. We used the Kaplan-Meier method, life table, and Cox proportional hazard models to evaluate the role of the comorbidities on mortality, with a significant P-value of < 0.05. All statistical tests were two-tailed.
Results: We included 2,514 patients, and 1,139 (45.3%) had a diagnosis of HFpEF or HFmrEF. HFpEF/HFmrEF diagnosis was not significantly related to either higher or lower risk of mortality compared to an HFrEF diagnosis; however, the individual risk factors for this outcome varied between the two groups. Health-related quality of life (HRQL) was a common risk factor for both groups.
Conclusion: Although the EF classification was not a significant risk factor for mortality, patients with HFpEF/HFmrEF exhibited a unique profile of risk factors for mortality, the HRQL, highlighting the relevance of an adequate classification of the HF patients.
