Effect of ischemic postconditioning on microvascular obstruction in reperfused myocardial infarction. Results of a randomized multicenter study in pa…
2013
Purpose: Ischemic Postconditioning (PCON) appears as a potentially beneficial tool to complement primary angioplasty in ST-segment elevation myocardial infarction (STEMI). We evaluated the impact of PCON on Microvascular Obstruction (MVO) both in patients and in a highly controlled swine model. Methods: In a multicenter study, 101 patients with a first STEMI were randomized to undergo primary angioplasty followed by PCON or primary angioplasty alone (non-PCON). MVO (lack of contrast uptake in the core of the hyperenhanced infarcted area) was quantified in late enhancement cardiac magnetic resonance imaging. In an anterior STEMI swine model based on a 90-min angioplasty balloon coronary occl…
Role of balloon occlusion for mononuclear bone marrow cell deposition after intracoronary injection in pigs with reperfused myocardial infarction
2008
Aims In clinical studies on cell therapy for acute myocardial infarction (MI), cells are usually applied by intracoronary infusion with balloon (IC/B). To test the utility of balloon occlusion, mononuclear bone marrow cell (MNC) retention after intracoronary infusion without balloon (IC/noB) was compared with IC/B and intramyocardial (IM) injection. Methods and results Four hours after LAD ligation in male pigs, reperfusion was allowed (confirmed by coronary angiography). Five days later, 1 × 108 autologous 111Indium-labelled MNC were injected IC/noB ( n = 4), IC/B ( n = 4), or IM ( n = 4). At 1 h the fraction of injected MNC that was detected in the heart was 4.1 ± 1.1% after IC/noB inject…
