BACKGROUND For coronary artery bypass graft (CABG) surgery, cardiopulmonary bypass (CPB) is required for many patients. However, this procedure has several risks. Our objective was to test the hypothesis that the minimal extracorporeal circulation circuit (MECC) is more advantageous than CPB for CABG surgery. METHODS We analyzed 17 patients submitted to(More)
In a prospective study made between 1 September 1996 and 31 December 2001, pediatric patients with a diagnosis of supravalvular aortic stenosis confirmed by a reduction in the aortic inner diameter and a gradient > or = 50 mmHg were detected. Of 83 patients with aortic stenosis, only 7 (8.4%) had supravalvular aortic stenosis. All 7 patients underwent(More)
Rev Esp Cardiol 2003;56(5):515-8 515 We prospectively analyzed patients who underwent simultaneous off-pump coronary artery bypass grafting and endarterectomy between March 1, 1997 and February 28, 2002. The incidence of perioperative myocardial infarction, need for inotropic support, morbidity, long-time functional class, and mortality were evaluated. Nine(More)
BACKGROUND Interleukin-6 (IL6) plays a role in atherogenesis as well as in most atherothrombotic phenomenon such as ST-segment elevation acute myocardial infarction (STEAMI). Our objective was to evaluate serum levels of IL6 as prognostic value for major clinical in-hospital events in patients with STEAMI. METHODS We studied consecutive patients with(More)
The results reliability is a predominant condition in the validity of clinical research. The observer agreement determination is a useful procedure in the confirmation of the obtained results in clinical research. The present work is a presentation of the basis about observer agreement and a review of national publications in cardiology, pneumology and(More)
OBJECTIVE To evaluate which is the best method to determine the left ventricular ejection fraction in heart transplant recipients: radionuclide ventriculography or gated SPECT, compared with echocardiography as the gold standard method.
