Contrast Echocardiography in Non-ST Elevation Myocardial Infarction

2014-07-23 21:09:06 | BioPortfolio


In patients with acute myocardial infarction, treatment logistics are primarily defined based upon ST segment shift in the electrocardiogram. While patients with ST elevation (STEMI) are forwarded to immediate coronary angiography and percutaneous coronary intervention, patients without ST elevation (NSTEMI) are initially medically treated and recommended coronary angiography within 48-72 hours.

Early invasive treatment has been found cost-effective in intermediate and high-risk NSTEMI patients and current guidelines recommend use of the Thrombolysis in Myocardial Infarction (TIMI) risk score to identify patients who will benefit from early intervention due to high risk of new infraction and cardiovascular death. However, new research has suggested that TIMI risk score may not always identify patients with severe angiographic disease.

The purpose of this study was to assess if contrast echocardiography could be used to identify NSTEMI patients with angiographically severe disease independent of their TIMI risk score.

Medical and Biotech [MESH] Definitions

A clinical syndrome defined by MYOCARDIAL ISCHEMIA symptoms; persistent elevation in the ST segments of the ELECTROCARDIOGRAM; and release of BIOMARKERS of myocardial NECROSIS (e.g., elevated TROPONIN levels). ST segment elevation in the ECG is often used in determining the treatment protocol (see also NON-ST ELEVATION MYOCARDIAL INFARCTION).

A myocardial infarction that does not produce elevations in the ST segments of the ELECTROCARDIOGRAM. ST segment elevation of the ECG is often used in determining the treatment protocol (see also ST Elevation Myocardial Infarction).

MYOCARDIAL INFARCTION in which the anterior wall of the heart is involved. Anterior wall myocardial infarction is often caused by occlusion of the left anterior descending coronary artery. It can be categorized as anteroseptal or anterolateral wall myocardial infarction.

MYOCARDIAL INFARCTION in which the inferior wall of the heart is involved. It is often caused by occlusion of the right coronary artery.

Laceration or tearing of cardiac tissues appearing after MYOCARDIAL INFARCTION.
