The feasibility, safety and usefulness of 2-dimensional echocardiography (2-D echo) during dobutamine infusion for identifying patients with multivessel coronary artery disease (CAD) after acute myocardial infarction (AMI) were evaluated in 30 patients 5 to 10 days after AMI. Patients underwent 2-D echo under basal conditions and during dobutamine infusion(More)
Of 1265 patients admitted to the CCU with the diagnosis of acute MI, 96 (7.6%) developed ventricular fibrillation within 72 hours following admission. Of these 96, 35 (36.5%) had secondary VF associated with left ventricular failure; they had a high in-hospital mortality of 57.1%. The remaining 61 (63.5%) had primary VF, i.e. VF occurring in the absence of(More)
Previous surveys have suggested that community alarm users are in general satisfied with the service provided. However, there is also evidence that users would like additional options that could be provided by a telecare system. Inner-city users of community alarms were consulted about their current systems and the extension of these to incorporate telecare(More)
1 The aim of this study was to evaluate the influence of renal insufficiency on the plasma pharmacokinetics of mexiletine, a new antiarrhythmic agent, in human beings. 2 Mexiletine was administered orally three times daily for 10 days to 15 patients with chronic renal failure (creatinine clearance lower than 30 ml/min) and to 9 subjects with normal renal(More)
To determine the incidence and clinical significance of pericardial effusion after acute myocardial infarction, two-dimensional echocardiography was serially performed in 66 consecutive patients. Pericardial effusion was observed in 17 (26%); the effusion was small in 13 patients, moderate in 3 and large with signs of cardiac tamponade in 1. In this(More)
This study examined the relative value of clinical, biochemical, echocardiographic and haemodynamic variables, obtained early after acute myocardial infarction in predicting in-hospital and one-year cardiac mortality in 66 consecutive patients. Clinical examination and cross-section echocardiography were obtained in all 66 patients. An echocardiographic(More)
To identify the haemodynamic response to ischaemia induced by dobutamine stress testing, 15 patients with a first acute myocardial infarction underwent right-sided heart catheterization during dobutamine stress cross-sectional echocardiography. Haemodynamic variables and echocardiography were recorded at rest and during dobutamine infusion at each dose from(More)
Two-dimensional echocardiography provides adequate spatial orientation and anatomic definition. Eighteen consecutive patients undergoing myocardial biopsy had concomitant two-dimensional echocardiography during 22 biopsies of five to six samples each. The transducer was placed at the apex and in the subcostal area and four-chamber views were used. The(More)
To delineate the clinical significance and prognostic importance of a history of chronic or new onset angina pectoris before acute myocardial infarction (AMI), 732 consecutive patients admitted for a first AMI were studied and divided into 3 groups. Two hundred patients (27%) had chronic angina before AMI (greater than 1 month); 247 patients (34%) had new(More)
To identify patients at risk of cardiac expansion during hospital stay for a first acute myocardial infarction (AMI), 41 patients underwent right-sided cardiac catheterization soon after admission and serial 2-dimensional echocardiography on days 1, 3 or 4 and between days 7 and 10. Infarct expansion was recognized by echocardiography in 11 patients (27%),(More)
