Natriuretic peptides: markers or modulators of cardiac hypertrophy?
The natriuretic peptides (NPs), through their diuretic, vasodilatory and anti-mitogenic properties, play an important role in the regulation of cardiovascular, renal and endocrine homeostasis. Recent studies suggest that they have utility in both the diagnosis and management of heart failure. Plasma brain NP (BNP) levels have been used to establish prognosis in patients with heart failure and those at risk for heart failure post-myocardial infarction. They have been used to establish a cardiac etiology for acute shortness of breath, and to guide and assess the efficacy of therapy in patients with established heart failure. BNP is also approved for use in the management of acute decompensated heart failure. Of note, recent studies suggest that cardiac NPs suppress myocyte hypertrophy and interstitial fibrosis in the heart, arguing for an important autocrine-paracrine role of these peptides in controlling the cardiac response during hypertrophy. Therefore, the existing evidence supports a role for BNP as both a marker and a modulator of hypertrophy.
