Sirolimus Eluting Stenting in Acute Myocardial Infarction

2014-07-23 21:46:16 | BioPortfolio

Summary

The incidence of stent restenosis in the setting of primary angioplasty is particularly high, reaching a rate of 27% In the last years the introduction of drug-eluting stents has drastically reduced the incidence of restenosis in patients not requiring urgent revascularization. Whether drug-eluting stenting might constitute the new optimal therapy for patients with an acute myocardial infarction is unknown. To be able to answer this question, we designed a randomized trial in which patients with an acute myocardial infarction eligible for treatment with primary angioplasty and abciximab were randomized to receive either a rapamicine-eluting stent or a conventional bare stent.

Description

The treatment of acute myocardial infarction has evolved dramatically in the last decade. Coronary angioplasty with stent implantation in conjunction with an optimal antitrombotic therapy as abciximab is now considered current standard therapy However, the incidence of stent restenosis in the setting of primary angioplasty remains particularly high, reaching a rate of 27%. A high restenosis rate causes a high re-hospitalization rate for target vessel revascularization and an ensuing increase in cost.In the last years the introduction of drug-eluting stents has drastically reduced the incidence of restenosis in patients not requiring urgent revascularization. This reduced incidence of restenosis occurs without an increase in adverse clinical events over conventional stents and has a very low rate of stent subacute thrombosis. Whether this combination of drug-eluting stents and abciximab might constitute the new optimal therapy for patients with an acute myocardial infarction is unknown. To be able to answer this question, we designed a one year coronary angiographic study in which patients with an acute myocardial infarction eligible for treatment with primary angioplasty and abciximab were randomized to receive either a rapamicine-eluting stent or a conventional bare stent.

Medical and Biotech [MESH] Definitions

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.

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).

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).

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

An episode of MYOCARDIAL ISCHEMIA that generally lasts longer than a transient anginal episode but that does not usually result in MYOCARDIAL INFARCTION.
