Background and Objectives: It has been demonstrated that the concentration of plasma nerve growth factor (NGF) effects nerve sprouting. In addition, the relationship between plasma NGF concentration and the occurrence of ventricular tachyarrhythmia (VT) has been reported in animal models of myocardial infarction (MI). However, the causal relationship between NGF and VT remains unclear in humans. The aim of the current study was to determine whether NGF is increased in patients with MI. In addition, the relationship between the concentration of plasma NGF and the inducibility of VT was evaluated.
Subjects and Methods: We studied 15 patients with stable angina pectoris (SA) and 30 patients with an acute MI (AMI). The patients in the AMI group were divided into VT occurrence (n=14) and non-VT occurrence groups (n=16). Thirty-four patients suspected to have VT underwent programmed electrical stimulation (PES) and were divided into an idiopathic VT group (n=24) and an induced VT with PES {healthy control (C) group; n=10}. Plasma NGF concentrations were measured by enzyme-linked immunosorbent assay (ELISA).
Results: The plasma concentrations of the AMI group were significantly increased compared to the C group {median (interquartile range), 18.9 (8.7) vs. 10.3 (12.5) pg/mL, p<0.05} and the patients with SA {18.9 (8.7) vs. 15.1 (6.7) pg/mL, p<0.05}, but not significantly different from those in the idiopathic VT group {median (interquartile range), 18.9 (8.7) vs. 18.7 (8.5) pg/mL, p=0.89}. There was no significant difference in the plasma NGF concentrations between the C and SA groups {10.3 (12.5) vs. 15.1 (6.7) pg/mL, p=0.18}. In the AMI patients, there was no significant difference in the plasma NGF concentrations between patients with VT and those without VT {18.5 (6.7) vs. 21.2 (10.2) pg/mL, p=0.25}.
Conclusion: The plasma NGF concentrations were increased in patients with an AMI compared to patients with SA and Cs.
