Influence of Spironolactone on Matrix Metalloproteinase-2 in Acute Decompensated Heart Failure.

Background: Matrix metalloproteinases (MMPs) are a family of enzymes important for the resorption of extracellular matrices, control of vascular remodeling and repair. Increased activity of MMP2 has been demonstrated in heart failure, and in acutely decompensated heart failure (ADHF) a decrease in circulating MMPs has been demonstrated along with successful treatment. Objective: Our aim was to test the influence of spironolactone in MMP2 levels. Methods: Secondary analysis of a prospective, interventional study including 100 patients with ADHF. Fifty patients were non-randomly assigned to spironolactone (100 mg/day) plus standard ADHF therapy (spironolactone group) or standard ADHF therapy alone (control group). Results: Spironolactone group patients were younger and had lower creatinine and urea levels (all p < 0.05). Baseline MMP2, NT-pro BNP and weight did not differ between spironolactone and control groups. A trend towards a more pronounced decrease in MMP2 from baseline to day 3 was observed in the spironolactone group (-21 [-50 to 19] vs 1.5 [-26 to 38] ng/mL, p = 0.06). NT-pro BNP and weight also had a greater decrease in the spironolactone group. The proportion of patients with a decrease in MMP2 levels from baseline to day 3 was also likely to be greater in the spironolactone group (50% vs 66.7%), but without statistical significance. Correlations between MMP2, NT-pro BNP and weight variation were not statistically significant. Conclusion: MMP2 levels are increased in ADHF. Patients treated with spironolactone may have a greater reduction in MMP2 levels.Fundamento: As metaloproteinases de matriz (MMPs) constituem uma família de enzimas importantes para a reabsorção da matriz extracelular e controle do remodelamento e da reparação vasculares. Demonstrou-se aumento da atividade de MMP2 na insuficiência cardíaca, e, na insuficiência cardíaca agudamente descompensada (ICAD), demonstrou-se uma diminuição nas MMPs circulantes juntamente com o tratamento bem-sucedido. Objetivos: Testar a influência da espironolactona nos níveis de MMP2. Métodos: Análise secundária de estudo prospectivo, intervencionista, incluindo 100 pacientes com ICAD, 50 designados não aleatoriamente para o uso de espironolactona (100 mg/dia) mais terapia padrão para ICAD (grupo espironolactona) e 50 para terapia padrão para ICAD apenas (grupo controle). Resultados: Os pacientes do grupo espironolactona eram mais jovens e tinham níveis mais baixos de creatinina e ureia (todos p < 0,05). Os valores basais de MMP2, NT-pro BNP e peso não diferiram entre os grupos espironolactona e controle. Observou-se tendência para uma redução mais pronunciada na MMP2 do basal para o dia 3 no grupo espironolactona (-21 [-50 a 19] vs 1,5 [-26 a 38] ng/ml, p = 0,06). Os valores de NT-pro BNP e peso também apresentaram maior diminuição no grupo espironolactona. A proporção de pacientes com redução nos níveis de MMP2 do basal para o dia 3 também foi maior no grupo espironolactona (50% vs 66,7%), embora sem significado estatístico. As correlações entre as variações de MMP2, NT-pro BNP e peso não apresentaram significado estatístico. Conclusões: Os níveis de MMP2 acham-se aumentados na ICAD. Pacientes tratados com espironolactona podem apresentar maior redução nos níveis de MMP2.
