Assessment of myocardial infarction by cardiac magnetic resonance imaging and long-term mortality.

Background: Cardiac magnetic resonance imaging provides detailed anatomical information on infarction. However, few studies have investigated the association of these data with mortality after acute myocardial infarction.

Objective: To study the association between data regarding infarct size and anatomy, as obtained from cardiac magnetic resonance imaging after acute myocardial infarction, and long-term mortality.

Clinical outcomes at 30 days in the Brazilian Registry of Acute Coronary Syndromes (ACCEPT).

Background: There are few registries documenting clinical practice in Brazilian patients with acute coronary syndrome.

Objectives: Demography description, occurrence of major clinical adverse events and comparative analysis in patients submitted or not to an invasive strategy (coronary angiography and myocardial revascularization) in a Brazilian multicenter registry of acute coronary syndrome.

Methods: The ACCEPT/SBC registry prospectively collected data on acute coronary syndrome patients from 47 Brazilian hospitals.

Prognostic value of CT angiography in patients with inconclusive functional stress tests.

Objectives: We attempted to determine the prognostic value of coronary computed tomographic angiography (CTA) in patients with inconclusive functional stress tests.

Background: Patients with suspected coronary artery disease (CAD) and inconclusive noninvasive cardiac stress tests represent a frequent management challenge.

Methods: We examined 529 consecutive patients with suspected CAD and prior inconclusive functional stress tests.

Enhanced inflammatory response to coronary stenting marks the development of clinically relevant restenosis.

Objectives: The aims of this study were to investigate the effect of coronary stenting on the release of cytokines and cell-mediated immunity factors and to evaluate the association between inflammation and clinical outcomes at 6 months.

Background: Circulating levels of inflammatory markers and cytokines are elevated in patients with acute coronary syndromes and are related to an unfavorable outcome. The aims of this study were to investigate the effect of coronary stenting on the release of cytokines and cell-mediated immunity factors and to evaluate the association between inflammation and clinical outcomes at 6 months.

Quantification of left ventricular infarcted mass on cardiac magnetic resonance imaging: comparison between planimetry and the semiquantitative visual scoring method.

Objective: To compare a new semiquantitative visual scoring method with quantitative digital planimetry for determining left ventricular infarcted mass by use of cardiac delayed contrast-enhanced magnetic resonance imaging.

Method: Seventy-seven patients with previous myocardial infarction underwent delayed contrast-enhanced magnetic resonance imaging using a 1.5T device for assessing myocardial viability and calculating the infarcted mass.
