Body surface mapping vs 12-lead electrocardiography to detect ST-elevation myocardial infarction.

A prospective, multicenter trial was conducted in patients with nontraumatic chest pain in 4 hospitals to determine whether an 80-lead body surface map electrocardiogram system (80-lead BSM ECG) improves detection of ST-segment elevation in acute myocardial infarction (STEMI) compared with a standard 12-lead electrocardiogram (ECG) in an emergency department (ED) setting. A trained ED or cardiology staff member (technician or nurse) recorded a 12-lead ECG and 80-lead BSM ECG from each subject at initial presentation. Serial biomarkers (total creatine kinase [CK], CK-MB, and/or troponin) were obtained according to individual hospital practice.

Prognostic impact of right ventricular involvement in patients with acute myocardial infarction: meta-analysis.

Objective: The objective of this study was to examine the relationship between right ventricular involvement (RVI) in acute myocardial infarction (AMI) and the increase in mortality and morbidity frequently suggested in the last two decades.

Design: The authors conducted a systematic review and meta-analysis.

Setting: This study was conducted at an academic medical center.

Diagnostic performance of 16- and 64-section spiral CT for coronary artery bypass graft assessment: meta-analysis.

Purpose: To perform a meta-analysis to evaluate the accuracy of 16- and 64-section spiral computed tomography (CT) to help assess coronary artery bypass grafts (CABGs).

Materials And Methods: The MEDLINE, Cochrane library, and BioMed Central databases were searched for relevant original articles published up to May 2007. Major criteria for article inclusion were that it (a) used multisection CT as a diagnostic test for the assessment of significant lesions (occlusion or >50% stenosis) of CABG, (b) used a 16- or 64-section scanner, and (c) used coronary angiography as the reference standard.

Prognostic impact of major bleeding in patients with acute coronary syndromes.A systematic review and meta-analysis.

Aims: The causative relationship between major bleeding in acute coronary syndromes (ACS) and the increase in mortality and morbidity has frequently been suggested in recent pharmaco-invasive trials and registries. However, the magnitude of this increased risk is the subject of debate. In order to determine the prognostic significance of major bleeding in ACS, we have conducted a systematic review and meta-analysis.

Coronary arteries: diagnostic performance of 16- versus 64-section spiral CT compared with invasive coronary angiography--meta-analysis.

Purpose: To perform a meta-analysis to compare the diagnostic performance of 16- versus 64-section computed tomography (CT) for the diagnosis of coronary artery disease (CAD).

Materials And Methods: The MEDLINE database was searched for relevant original articles. Criteria for inclusion of articles were (a) use of multisection spiral CT as a diagnostic test for obstructive CAD, (b) use of the newer generation of multisection spiral CT (16 or 64 section) scanners, and (c) use of coronary angiography as the reference standard for diagnosing obstructive CAD (>50% diameter stenosis was selected as the cutoff criterion for diagnosis of CAD).

Diagnostic accuracy of in-stent coronary restenosis detection with multislice spiral computed tomography: a meta-analysis.

This study was designed to define the current role of multislice spiral computed tomography (MSCT) for the diagnosis of coronary in-stent restenosis using a meta-analytic process. Restenosis remains a limitation after coronary stent implantation and contributes to a substantial number of coronary re-assessments by conventional invasive coronary angiography (CA). We identified 15 studies (807 patients) evaluating in-stent restenosis by means of both MSCT (>or=16 slices) and conventional CA until February 2007.

To examine the effectiveness of a hospital-based nurse-led secondary prevention clinic.

Modification of cardiovascular risk factors can reduce the incidence of myocardial infarction (MI), effectively extend survival, decrease the need for interventional procedures, and improve quality of life in persons with known cardiovascular disease. Pharmacological treatments and important lifestyle changes reduce people's risks substantially (by 1/3 to 2/3) and can slow and perhaps reverse progression of established coronary disease. When used appropriately, these interventions are more cost-effective than many other treatments, currently provided by the National Health Service [Department of Health National Service Frameworks: coronary heart disease.

Prehospital 80-LAD mapping: does it add significantly to the diagnosis of acute coronary syndromes?

Unlabelled: Early detection of acute myocardial infarction (MI) is vital in the management of acute coronary syndromes (ACS). Hence we compared the diagnostic capability of the standard 12-lead electrocardiogram (ECG) with the 80-lead ECG body surface map (BSM) prehospital.

Methods: Consecutive patients (n = 294) presenting prehospital with ischemic type chest pain were included.

Body surface potential mapping improves detection of ST segment alteration during percutaneous coronary intervention.

Background: The 12-lead electrocardiogram underestimates ST segment alteration in acute coronary syndromes compared with multi-lead body surface mapping. We assessed whether 80-lead mapping would improve detection of ST alteration during percutaneous coronary intervention.

Methods: Simultaneous maps and 12-lead electrocardiograms were recorded pre-procedure, during balloon inflation and post-procedure from patients undergoing elective intervention to native coronary arteries.
