Papel dos parâmetros inflamatórios do leucograma e das plaquetas na insuficiência cardíaca descompensada : estudo observacional retrospetivo

Abstract

Introdução: A Insuficiência Cardíaca (IC) é uma síndrome inflamatória sistémica incurável. A inflamação tem um papel no desenvolvimento, progressão e complicações da IC, sendo causa e consequência desta. Alguns parâmetros inflamatórios podem ser potenciais biomarcadores de gravidade e prognóstico da IC. Objetivo: Investigar o valor prognóstico da contagem total e diferencial de leucócitos, plaquetas e rácios neutrófilos-linfócitos (RNL), monócitos-linfócitos (RML) e plaquetas-linfócitos (RPL) em doentes com IC. Métodos: Realizou-se um estudo observacional retrospetivo em indivíduos hospitalizados por IC descompensada classes III ou IV NYHA. Os índices inflamatórios estudados foram comparados com indicadores de gravidade definidos: NT-proBNP, FEj e mortalidade a 18 meses. A análise estatística foi realizada através do IBM SPSS Statistics 22. Resultados: Foram incluídos 65 indivíduos – 43,1% homens. A média de idades foi 79,25 (± 10.75) anos e a FEj 48,86% (± 18,21). A mortalidade a 18 meses foi 41,54%. O NT-proBNP apresentou correlação inversa com: FEj (coeficiente de correlação = - 0,479, p < 0,01); colesterol total (coeficiente de correlação = - 0,551, p < 0,01); HDL (coeficiente de correlação = - 0,589, p < 0,01); e IMC (coeficiente de correlação = - 0,483, p < 0,01). Num modelo de regressão linear múltipla, o NT-proBNP manteve associação inversa significativa com FEj (p = 0,011), HDL (p = 0,014) e IMC (p = 0,022). No qui-quadrado, a FEj relacionou-se com RNL (p = 0,018); e o edema agudo do pulmão com RNL (p = 0,024) e RPL (p = 0,023). As curvas de Kaplan-Meier foram significativas para leucócitos (p = 0,044) e IMC (p = 0,026). Conclusão: A leucopénia e o aumento dos rácios RNL e RPL, associados a um IMC baixo, poderão indicar um pior prognóstico nos indivíduos com IC descompensada de classes NYHA III e IV.

Introduction: Heart failure (HF) in an incurable systemic inflammatory syndrome. Inflammation plays a role in the development, progression and complications of HF, being its cause and consequence. Some inflammatory parameters may be potential biomarkers of HF severity and prognosis. Objectives: To investigate the prognostic value of total and differential white blood cell count, platelets and neutrophil-lymphocyte (NLR), monocyte-lymphocyte (MLR) and platelet-lymphocyte (PLR) ratios in patients with HF. Methods: We conducted a retrospective observational study in individuals hospitalized for NYHA class III and IV decompensated HF. The inflammatory indices were compared with defined severity indicators: NT-proBNP, EF and 18-month mortality. Statistical analysis was performed using IBM SPSS Statistics 22. Results: 65 patients were included – 43,1% male. Mean age was 79,25 (± 10.75) years and EF 48.86% (± 18.21). 18-month mortality was 51,86%. NT-proBNP correlated inversely with: EF (correlation coefficient = - 0.479, p < 0.01); total cholesterol (correlation coefficient = - 0,551, p < 0,01); HDL (correlation coefficient = - 0,589, p < 0,01); and BMI (correlation coefficient = - 0,483, p < 0,01). In a multiple linear regression model, NT-proBNP maintained significant inverse association with EF (p = 0,011), HDL (p = 0,014) and BMI (p = 0,022). In the chi-square, EF was related to NLR (p = 0,018); and acute pulmonary edema with NLR (p = 0,024) and PLR (p = 0,023). Kaplan-Meier curves were significant for leukocytes (p = 0,044) and BMI (p = 0,026). Conclusion: Leukopenia and increased RNL and RPL ratios, associated with a low BMI, may indicate a worse prognosis in individuals with decompensated HF NYHA class III and IV.
