Impact of electrical neurostimulation on persistent ST elevation after successful reperfusion by primary percutaneous coronary intervention.

Abstract：

AIMS:To study the effect of electrical neurostimulation on the ST segment shift in patients with ST elevation myocardial infarction (STEMI) with residual ST elevation after primary percutaneous coronary intervention (PCI). METHODS:After primary PCI, 38 patients with STEMI were divided into 2 groups. Group 1 received 15 minutes of active neurostimulation after the baseline electrocardiogram (ECG); group 2 received 15 minutes of active neurostimulation after 15 minutes of nonactive neurostimulation. RESULTS:In group 1, ST elevation decreased with neurostimulation from 0.65 +/- 0.56 to 0.55 +/- 0.51 (P = .02) and to 0.50 +/- 0.52 (P = .01) without electrical neurostimulation. In group 2, ST elevation changed without neurostimulation from 0.37 +/- 0.32 to 0.33 +/- 0.30 (P = NS) and to 0.28 +/- 0.27 (P = .01) with electrical neurostimulation. In a posthoc analysis, 17 responders had higher ST elevation at the ECG before active electrical neurostimulation than 21 nonresponders (P = .001). CONCLUSION:Electrical neurostimulation may result in significant additional reduction of ST elevation in STEMI after reperfusion treatment, in particular in patients with marked ST elevation on the first ECG after successful primary PCI.
