ABSTRACT
Background/Aims@#The Heart Failure Association (HFA)-PEFF score is recognized as a simple method to diagnose heart failure (HF) with preserved ejection fraction (HFpEF). This study aimed to evaluate the relationship between HFA-PEFF scores and cardiovascular outcomes in HFpEF patients. @*Methods@#A total of 502 consecutive HFpEF patients were prospectively observed for up to 1,500 days. Cardiovascular outcomes were compared between two groups of patients, defined by their HFA-PEFF scores: those who scored 2–4 (the intermediate-score group) and those who scored 5–6 group (the high-score group). Overall, 236 cardiovascular events were observed during the follow-up period (median, 1,159 days). @*Results@#Kaplan-Meier analysis showed that there were significant differences in composite cardiovascular events and HF-related events between the intermediate-score group and the high-score group (p = 0.003 and p < 0.001, respectively). Multivariate Cox proportional hazards analysis showed that the HFA-PEFF scores significantly predicted future HF-related events (hazard ratio, 1.66; 95% confidence interval [CI], 1.11 to 2.50; p = 0.014); receiver operating characteristic analysis confirmed this relationship (area under the curve, 0.633; 95% CI, 0.574 to 0.692; p < 0.001). The cutoff HFA-PEFF score for the identification of HF-related events was 4.5. Decision curve analysis revealed that combining the HFA-PEFF score with conventional prognostic factors improved the prediction of HF-related events. @*Conclusions@#HFA-PEFF scores may be useful for predicting HF-related events in HFpEF patients.
ABSTRACT
Avaliar a capacidade física de uma criança com obesidade exógena. Relato de caso: Paciente com 8 anos, obesa, com crise asmática e cansaço aos esforços. Foi submetida a quatro avaliações do teste de caminhada de seis minutos (TC6), com intervalo de seis meses entre as consultas, para avaliação da capacidade física, com subseqüentes orientações para a realização de exercícios físicos e caminhadas diárias. Em cada avaliação, a criança foi submetida ao TC6 e considerado o teste de maior distância percorrida. Discussão: Após o término do estudo, observou-se que o TC6´ pode ser uma importante ferramenta clínica na avaliação cardiorrespiratória de crianças obesas pré e pós um programa de exercícios...
To evaluate the physical capacity of a child with exogenous obesity. Case report: Eight year-old female patient, obese, with asthmatic crisis and uncomfortable with physical activities. She undertook four evaluations of the six minute walk test (6WT), within 6-month intervals between each consultation, in order to evaluate her physical capacity after recommendations of physical exercises and daily walks. In each evaluation, the child was submitted to the 6WT, considering that with the highest distance. Discussion: This study shows that the 6WT can be an important clinical tool to the cardiorespiratory evaluation of obese children before and after an exercise program...
