## TL;DR

This study compares two clinical scores for predicting outcomes in heart failure patients with preserved ejection fraction, finding one more effective than the other.

## Contribution

The study evaluates the prognostic performance of H2FPEF and HFA-PEFF scores in a Brazilian HFpEF cohort, showing H2FPEF's superior predictive ability.

## Key findings

- H2FPEF score demonstrated better predictive ability (AUC: 0.637) compared to HFA-PEFF (AUC: 0.572) for cardiovascular outcomes.
- High-probability classification by both scores was significantly associated with adverse outcomes (log-rank p=0.034).

## Abstract

Os escores H2FPEF e HFA-PEFF foram desenvolvidos para auxiliar no diagnóstico da insuficiência cardíaca com fração de ejeção preservada (ICFEP) e podem ser úteis na predição de desfechos cardiovasculares.

Avaliar a aplicação prognóstica desses escores em uma coorte de indivíduos com ICFEP.

Este estudo prospectivo foi conduzido em um hospital terciário no Brasil entre março de 2019 e dezembro de 2021. Após a realização de exames clínicos, ecocardiograma e teste de exercício, os escores H2FPEF e HFA-PEFF foram calculados. Os pacientes foram classificados em grupos de probabilidade intermediária (H2FPEF: 2-5 pontos; HFA-PEFF: 2-4 pontos) e alta (H2FPEF >5 pontos; HFA-PEFF >4 pontos). O desfecho primário foi um composto de mortalidade por todas as causas e hospitalizações por ICFEP. O nível de significância estatística foi estabelecido em p<0,05.

Um total de 103 pacientes foi acompanhado por um período médio de 888 dias (±291), com idade média de 69 anos (±8,3), sendo 61% do sexo feminino. Vinte e sete pacientes (26,2%) apresentaram desfechos primários, totalizando 32 eventos, dos quais 11 foram óbitos e 21, hospitalizações por ICFEP. Na análise de curva receiver operating characteristic (ROC), o escore H2FPEF demonstrou melhor capacidade preditiva para os desfechos (area under the curve [AUC]: 0,637, IC 95%: 0,518-0,756, p=0,035), em comparação ao escore HFA-PEFF (AUC: 0,572, IC 95%: 0,448-0,696, p=0,270). Na análise de Kaplan-Meier, a classificação de alta probabilidade por ambos os escores foi significativamente associada à ocorrência de desfechos (log-rank p=0,034), quando comparada aos grupos com escores intermediários ou com resultados divergentes entre os dois escores.

O escore H2FPEF apresentou desempenho superior ao HFA-PEFF na predição de desfechos em pacientes com ICFEP. Os resultados deste estudo contemporâneo realizado no Brasil contribuem para a estratificação de risco na prática clínica.

The H2FPEF and HFA-PEFF scores were developed to support the diagnosis of heart failure with preserved ejection fraction (HFpEF) and may also help predict cardiovascular outcomes.

To assess the prognostic value of these scores in a cohort of individuals with HFpEF.

This prospective study was conducted at a tertiary hospital in Brazil between March 2019 and December 2021. After clinical evaluation, echocardiography, and exercise testing, the H2FPEF and HFA-PEFF scores were calculated. Patients were classified into intermediate probability groups (H2FPEF: 2-5 points; HFA-PEFF: 2-4 points) and high probability groups (H2FPEF >5 points; HFA-PEFF >4 points). The primary outcome was a composite of all-cause mortality and hospitalizations due to HFpEF. Statistical significance was set at p<0.05.

A total of 103 patients were followed for an average of 888 days (±291). The mean age was 69 years (±8.3), and 61% were women. Twenty-seven patients (26.2%) experienced primary outcomes, totaling 32 events—11 deaths and 21 hospitalizations due to HFpEF. In the receiver operating characteristic (ROC) curve analysis, the H2FPEF score showed better predictive ability for the outcomes (area under the curve [AUC]: 0.637, 95% CI: 0.518–0.756, p=0.035) compared to the HFA-PEFF score (AUC: 0.572, 95% CI: 0.448–0.696, p=0.270). In the Kaplan-Meier analysis, high-probability classification by both scores was significantly associated with the occurrence of outcomes (log-rank p=0.034), compared to the intermediate score group or patients with differing classifications between the two scores.

The H2FPEF score showed better performance than the HFA-PEFF score in predicting outcomes in patients with HFpEF. Findings from this contemporary study conducted in Brazil contribute to risk stratification in clinical practice.
