- ItemEffect of primary coronary angioplasty on left ventricular function and myocardial perfusion as determined by Tc-99m sestamibi scintigraphy(EXCERPTA MEDICA INC-ELSEVIER SCIENCE INC, 2001) Castro, PF; Corbalan, R; Baeza, R; Nazzal, C; Greig, DP; Miranda, FP; Gonzalez, R; Marchant, E; Olea, E; Larrain, GTwenty-foul consecutive patients undergoing primary angioplasty were systematically studied with technetium-99m sestamibi myocardial scanning before intervention at 72 hours and at 3 months. Treatment with primary angioplasty was associated with a significant early decrease in the perfusion defect size, followed by a later improvement in left ventricular dimensions and ejection fraction.
- ItemEffects of glucose-insulin-potassium solution on myocardial salvage and left ventricular function after primary angioplasty(LIPPINCOTT WILLIAMS & WILKINS, 2003) Castro, PF; Larrain, G; Baeza, R; Corbalan, R; Nazzal, C; Greig, DP; Miranda, FP; Perez, O; Acevedo, M; Marchant, E; Olea, E; Gonzalez, RObjective. To evaluate the effects of glucose-insulin-potassium (GIK) therapy on infarct size and left ventricular function when used as an adjuvant therapy to primary angioplasty.
- ItemOral rapamycin to prevent human coronary stent restenosis(2004) Guarda, E; Marchant, E; Fajuri, A; Martínez, A; Morán, S; Mendez, M; Uriarte, P; Valenzuela, E; Lazen, RBackground Recent human trials with rapamycin-eluting stents have shown very low restenosis rates. However, the high costs of these devices preclude their use in routine angioplasty, especially when considering multiple stenting. We evaluated whether orally administered rapamycin inhibits in-stent neointimal growth in patients with unstable angina.
- ItemPredictors of radial artery patency for coronary bypass operations(ELSEVIER SCIENCE INC, 2001) Moran, SV; Baeza, R; Guarda, E; Zalaquett, R; Irarrazaval, MJ; Marchant, E; Deck, CBackground. Few data exist regarding angiographic predictors of radial artery patency for coronary bypass grafting, and the benefit of calcium antagonists is not clear.
- ItemRelation of stenting to decreased coronary blood flow during primary angioplasty in acute myocardial infarction(2001) Escobar, J; Guarda, E; Marchant, E; Fajuri, A; Martínez, A; Pichard, AIn primary angioplasty of acute myocardial infarction, stent implantation decreased coronary blood flow in a third of patients, caused no change in another third, and improved coronary blood flow in the last third.
