stress echocardiography and exercise Electrocardiography for risk stratification after non q wave uncomplicated myocardial infarction
American Journal of Cardiology, 1999Co-Authors: Alessandro Desideri, Gian Leone Suzzi, Ciro Coletta, Gino Valente, Dario Gregori, Riccardo Bigi, Paolo M FiorettiAbstract:: The aim of our study was to compare the prognostic value of stress echocardiography and exercise Electrocardiography after uncomplicated non-Q-wave acute myocardial infarction in a series of 68 consecutive patients. Our data show that stress echocardiography and exercise Electrocardiography offer similar prognostic information after uncomplicated non-Q-wave AMI.

diagnostic value of exercise Electrocardiography and dipyridamole stress echocardiography in hypertensive and normotensive chest pain patients with right bundle branch block
Journal of Hypertension, 2003Co-Authors: Lauro Cortigiani, Fausto Rigo, Umberto Baldini, Pier Romano Mariani, Patrizia Landi, Riccardo Bigi, Eugenio PicanoAbstract:OBJECTIVES: Studies on the diagnostic value of exercise Electrocardiography in right bundle branch block produced controversial results, and data on the accuracy of stress echo are still lacking. The aim of the study was to compare the diagnostic value of exercise Electrocardiography and dipyridamole stress echo in chest pain patients with right bundle branch block, and to verify whether stress testing accuracy is affected by history of hypertension. METHODS: The study group was made up of 71 patients (56 men, aged 63 +/- 8 years) with chest pain of unknown origin and complete right bundle branch block. Of them, 35 were hypertensives and 36 normotensives. Patients performed, on different days and in random order, exercise Electrocardiography and dipyridamole stress echo and underwent coronary angiography. RESULTS: Significant (> or = 70% diameter stenosis) coronary artery disease was found in 34 patients (17 hypertensives and 17 normotensives). Positive exercise Electrocardiography (ST-segment shift > 1 mm at 80 ms after the J point in leads V5 and V6 or leads II and Vf) and dipyridamole stress echo (new wall motion abnormalities) were observed in 38 and 30 patients, respectively. The result of tests was concordant in 69% of hypertensives and 92% of normotensives. The two tests shared the same sensitivity in hypertensives (82%) and normotensives (71%). Of 37 patients without coronary artery disease, 12 had a false-positive result during exercise Electrocardiography and four during stress echo. The specificity was lower for exercise Electrocardiography than for stress echo in hypertensives (50 versus 89%, P = 0.0006), while no difference was evidenced in normotensives (84 versus 89%, P = 0.4). In hypertensives, the accuracy, positive, and negative predictive values were 66, 61, and 75% for exercise Electrocardiography, and 86, 87, and 84% for stress echo. Corresponding figures in normotensives were 78, 80, and 76% for exercise Electrocardiography, and 81, 86, and 77% for stress echo. CONCLUSIONS: In chest-pain patients with right bundle branch block, dipyridamole stress echo was effective to diagnose coronary artery disease in both normotensives and hypertensives. Moreover, it exhibited superior diagnostic information than exercise Electrocardiography in hypertensives, due to significantly higher specificity. However, the two tests had similar diagnostic value in normotensives.

delays in thrombolytic therapy for acute myocardial infarction association with mode of transportation to the hospital age sex and race
American Journal of Critical Care, 2001Co-Authors: Leslie L Davis, J J Evans, J D Strickland, L K Shaw, Galen S WagnerAbstract:BACKGROUND: Although increased myocardial salvage and reduced mortality are associated with timely thrombolytic therapy for acute myocardial infarction, some patients still experience delays in treatment. OBJECTIVES: To examine treatment times in patients with acute myocardial infarction treated with thrombolytic therapy and to determine whether delays in treatment are associated with mode of transportation to the hospital, age, sex, or race. METHODS: Medical records of 176 patients with acute myocardial infarction treated with thrombolytic therapy at a community hospital were reviewed and analyzed retrospectively. RESULTS: Median times for the interval between arrival at the hospital and acquisition of a diagnostic electrocardiogram (door-to-Electrocardiography time) and the interval between arrival and start of thrombolytic therapy (door-to-drug time) were 6 minutes and 34 minutes, respectively. However, 76.1% of the patients met the recommendation of the American College of Cardiology/American Heart Association of door-to-Electrocardiography time of 10 minutes, and 47.2% met the recommendation of door-to-drug time of 30 minutes or less. Door-to-drug times did not differ significantly according to race or mode of transportation to the hospital. Door-to-Electrocardiography and Electrocardiography-to-drug times were significantly longer for older patients than for younger patients (P = .005 and P < .001, respectively), and Electrocardiography-to-drug times were significantly longer for females than for males (P = .01). CONCLUSIONS: With increased emphasis on recognition and rapid treatment of patients with acute myocardial infarction at highest risk for delays in treatment, that is, women and the elderly, benefits of thrombolytic therapy might be maximized.

1994Co-Authors: Galen S WagnerAbstract:Part 1 The basic concepts: cardiac electrical activity recording the electrocardiogram interpretation of the normal electrocardiogram. Part 2 Abnormal wave morphology: chamber enlargement intraventricular conduction abnormalities ventricular pre-excitation myocardial ischemia and infarction electrocardiogram changes of ischemia due to increased myocardial demand electrocardiogram changes of ischemia due to insufficient blood supply electrocardiogram changes of infarction. Part 3 Abnormal rhythms: tachyarrhythmias - extrasystoles, sinus and other accelerated pacemaker tachycardias, atrial flutter fibrillation, AV junctional tachycardias, aberrant ventricular conduction from a superventricular tachycardia, ventricular tachycardia and fibrillation bradarrhythmias - sinus pauses and sinus arrest, AV block, artificial pacemakers.
