Prasugrel has quicker onset so it can be loaded later than clopidogrel with greater efficacy. However, prasugrel is much more expensive than clopidogrel. Objectives: To describe the incidence of 30-day death from cardiovascular causes, myocardial infarction, unstable angina requiring intervention, and minor and major bleeding in patients loaded with 60 mg of prasugrel prior to percutaneous coronary intervention (PCI) and then continued on 75 mg of clopidogrel daily after the procedure. Methods: We reviewed sequential medical records of 102 patients (Mean age: 67.8, male 68.6%, smokers: 22.6%, BMI: 29.5%, hypertension: 90.2%, DM: 33.3%, average ejection fraction: 49.7%) who underwent PCI (3.9% STEMI, 12.7% NSTEMI, 35.3% unstable angina and 48.1% electively) at Baylor University Medical Center between October 2009 and December 2011 who were loaded with prasugrel 60 mg prior to procedure, and then continued on 75 mg clopidogrel daily.

The use of this stent resulted in complete obliteration of the fistulous tract and restoration of flow into the sequential limb of the graft. Cathet Cardiovasc Intervent 2001;54:531-532.

The data demonstrated that dobutamine is a powerful inotropic agent at a dose that has a relatively small influence on heart rate. In patients without coronary artery disease dobutamine greatly increased coronary arterial perfusion. In patients with severe coronary artery diseases dobutamine resulted in a much smaller increase in coronary perfusion, and the pattern of perfusion became more inhomogeneous. The results suggest that dobutamine has a potential inotropic value but raise concern about its influence on regional myocardial perfusion in patients with serious coronary artery disease.

Newer devices, used to measure activated clotting time (ACT), have not been thoroughly tested for use with bivalirudin. One such device, the i-STAT ACT, measures the generation of activated thrombin to determine the level of anticoagulation. Our study demonstrated a high level of agreement between the i-STAT ACT and the Hemochron ACT in patients anticoagulated with bivalirudin. In addition, the i-STAT was shown to have an extremely high degree of reproducibility. ᮊ2004 by Excerpta Medica, Inc.

No observations occurred in 246 of 250 patients (98.4%) (1-sided 95% confidence interval 96.4%). Of the 250 patients, 4 had observations that were discovered at the prehospital discharge check and required reprogramming to increase the sensitivity safety margin (3 atrial and 1 ventricular). We documented only 1 complication that was discovered before the predischarge evaluation through telemetry and resulted in an atrial lead revision.

In six patients with S-T-elevation inferiorly, three had normal coronary arteriograms, one had complete right coronary artery occlusion, one had diffuse triple-vessel disease, and one did not undergo coronary arteriography. In two patients with S-T-elevation anteriorly, severe stenosis of the anterior descending coronary artery was present. Medical treatment in four patients and surgical revascularization of the anterior descending coronary artery in two patients were both accompanied by marked symptomatic improvement. Spontaneous loss of angina occurred in two patients. During 17 months' mean follow-up, seven patients have remained free of angina and one died suddenly. Variant angina pectoris may be accompanied by a variety of coronary arteriographic findings and the prognosis appears more favorable than previously reported.
