ABSTRACT
Abstract

Background:

Elevated plasma levels of Lipoprotein(a) [Lp(a)] are recognized as a significant risk factor for atherosclerotic vascular disease. However, there are limited data regarding association between Lp(a) and recurrent heart failure (HF) in patients with chronic HF caused by coronary heart disease (CHD).

Objective:

Elevated levels of Lp(a) might have a prognostic impact on recurrent HF in patients with chronic HF caused by CHD.

Methods:

A total of 309 patients with chronic HF caused by CHD were consecutively enrolled in this study. The patients were divided into 2 groups according to whether Lp(a) levels were above or below the median level for the entire cohort (20.6 mg/dL) the high Lp(a) group (n = 155) and the low Lp(a) group (n = 154). A 2-sided p < 0.05 was statistically considered significant.

Results:

During the median follow-up period of 186 days, 31 cases out of a total of 309 patients (10.03%) could not be reached during follow-up. A Kaplan-Meier analysis demonstrated that patients with higher Lp(a) levels had a higher incidence of recurrent HF than those with lower Lp(a) levels (log-rank < 0.0001). A multivariate Cox regression analysis revealed that Lp(a) levels were independently correlated with the incidence of recurrent HF after adjustment of potential confounders (hazard ratio 2.720, 95 % confidence interval 1.730-4.277, p < 0.0001).

Conclusions:

In Chinese patients with chronic HF caused by CHD, elevated levels of Lp(a) are independently associated with recurrent HF.
RESUMO
Resumo Fundamento Níveis plasmáticos elevados de lipoproteína (a) [Lp(a)] são reconhecidos como um fator de risco significativo para doença vascular aterosclerótica. No entanto, existem dados limitados sobre a associação entre a Lp(a) e insuficiência cardíaca (IC) recorrente em pacientes com IC crônica causada por doença arterial coronariana (DAC).

Objetivo:

Níveis elevados de Lp(a) podem ter um impacto prognóstico na IC recorrente em pacientes com IC crônica por DAC.

Métodos:

Um total de 309 pacientes com IC crônica causada por DAC foram consecutivamente incluídos neste estudo. Os pacientes foram divididos em 2 grupos de acordo com os níveis de Lp(a), acima ou abaixo do nível mediano de toda a coorte (20,6 mg/dL) o grupo Lp(a) alto (n = 155) e o grupo Lp ( a) baixo (n = 154). Um p < 0,05 bicaudal foi considerado estatisticamente significativo.

Resultados:

Durante a mediana do período de seguimento de 186 dias, 31 casos de um total de 309 pacientes (10,03%) não puderam ser contatados durante o acompanhamento. A análise de Kaplan-Meier demonstrou que pacientes com níveis mais elevados de Lp(a) apresentavam maior incidência de IC recorrente do que aqueles com níveis mais baixos de Lp(a) (log-rank < 0,0001). Uma análise de regressão multivariada de Cox revelou que os níveis de Lp(a) foram independentemente correlacionados com a incidência de IC recorrente após ajuste de potenciais fatores de confusão (hazard ratio 2,720, intervalo de confiança de 95% 1,730-4,277, p < 0,0001).

Conclusões:

Em pacientes chineses com IC crônica causada por DAC, níveis elevados de Lp(a) estão associados de forma independente à IC recorrente.
