Research Abstract |
I investigated clinical significance of vagal nerve stimulation as an adjunct therapy to coronary reperfusion in patients with acute myocardial infarction. Using a rabbit model of myocardial ischemia reperfusion, I disclosed that early short term vagal nerve stimulation in myocardial ischemia reperfusion drastically attenuates cardiac remodeling and prevents cardiac failure in chronic phase. Using dogs, I investigated whether electrical stimulations directly applied to the heart can increase cardiac contractility thereby preventing unwanted side effects such as hypotension seen in vagal nerve stimulation. I disclosed that several methods previously reported failed to increase the contractility constantly in my experimental settings.
