In vitro studies demonstrated a relationship between ET-1 and basic Fibroblast Growth Factor (bFGF), and of bFGF with Platelet Derived Growth Factor (PDGF). The present study was carried out to investigate in vivo the behaviour after vascular stress of circulating ET-1, bFGF and PDGF, and catecholamines, and their relationship. In 12 healthy normotensives (NTs) and 15 essential hypertensives (Ehs) venous blood samples to determine circulating ET-1, bFGF and PDGF, and catecholamine (EPI and NE) levels were drawn before and at the third minute of a handgrip test. Blood pressures (BP) and heart rate were automatically recorded before starting, and at 1, 2, and 3 minutes during the test. The NTs showed, in basal condition, lower values than the EHs of all the examined parameters; later, the handgrip test induced significant increases in circulating levels of ET-1, bFGF and catecholamine. In the EHs at the third minute of the exercise significant increases in plasma ET-1 (p < 0.002), bFGF (p < 0.006), and EPI and NE (p < 0.0005) levels were observed. Systolic and diastolic BP significantly increased after handgrip test in NTs and EHs. Plasma ET-1 correlated with bFGF both before (p < 0.01) and at the acme (p < 0.05) of the isometric exercise. Our results show that in EHs plasma ET-1 and bFGF correlate each other, indicating that in human hypertension a linkage between ET-1 and bFGF exists.
