Abstract
INTRODUCTION
The association of patients with heart failure (HF) and preserved ejection fraction (HFpEF) and with type 2 diabetes mellitus (T2DM) is strong and related additionally to blood pressure (BP).
AIMS
To analyze distinctive clinical profiles among patients with HFpEF both with and without T2DM.
METHODS
The study was based on a Spanish National Registry (multicenter and prospective) of patients with HF (DICUMAP), that enrolled outpatients with HF who underwent an ambulatory BP monitoring (ABPM) and then were followed-up for 1 year. We categorized patients according to the presence/absence of T2DM then building different clusters based on K-medoids algorithm.
RESULTS
103 patients were included. T2DM was present in 44.7%. The patients with T2DM were grouped into two clusters and those without T2DM into three. All patients with T2DM had kidney disease and anemia. Among them, cluster 2 had higher systolic blood pressure and pulse pressure (PP) with a bad outcome (p = 0.03) regarding HF mortality and readmissions, influenced by eGFR (HR 0.93, 95% CI 0.97-0.87, p = 0.04), and hemoglobin (HR 0.65, 95% CI 0.71-0.63, p = 0.03). Among those without T2DM, cluster 3 had a pathological ABPM pattern with the highest PP, cluster 4 was slightly similar to cluster 2, and cluster 5 expressed a more benign pattern without differences on both, HF mortality and readmissions.
CONCLUSIONS
Patients with HFpEF and T2DM expressed two different profiles depending on neurohormonal activation and arterial stiffness with prognostic implications. Patients without T2DM showed three profiles depending on ABPM pattern, kidney disease and PP without prognostic repercussion.
