Thrombus Aspiration in Myocardial Infarction
Treatment of myocardial infarction (blood clot in the arteries of the heart) has improved after introduction of 24/7 balloon angioplasty to open the blocked artery. However, the clot itself is not routinely removed but recent data in smaller trials indicate that this might improve recovery and prognosis. In this multicenter study of 5000 patients referred to Scandinavian hospitals for myocardial infarction the investigators test the hypothesis that patients randomized to treatment with thrombus aspiration (removing the blood clot by manual suction) before conventional angioplasty will have a reduced risk of death, fewer rehospitalisations, fewer new myocardial infarctions, reduced risk of heart failure, better coronary artery flow after angioplasty and greater reduction of infarct size compared to patients randomized to conventional angioplasty alone.

In patients with acute ST-segment elevation myocardial infarction (STEMI), percutaneous coronary intervention (PCI) may cause thrombus dislodgment and impaired microcirculatory reperfusion...
This is a multicenter, open-label, controlled, single-blind, randomized study with up to 452 subjects enrolled in up to 40 US and European sites. Subjects who present with anterior ST-elev...
In this trial, the investigators will evaluate the effect of thrombus aspiration followed by stent implantation in improving myocardial blush grade in patients with acute non-ST-elevation ...
The present study was designed to investigate whether the thrombus aspiration using Export Aspiration Catheter (Medtronic Corporation, California, USA) during primary percutaneous coronary...
Distal embolization can occur during coronary angioplasty performed in the acute phase of myocardial infarction and is associated with poor long-term outcome. We hypothesize that the use o...
Published reports demonstrate improved myocardial reperfusion with adjunctive thrombus aspiration in ST-elevation myocardial infarction (STEMI). However, implementation of this procedure without angio...
Thrombus aspiration is useful in improving myocardial reperfusion in comparison to conventional percutaneous coronary intervention in patients with acute myocardial infarction. Nonetheless, assessment...
Thrombus formation is a dynamic process regulated by flow, blood cells, and plasma proteins. The present study was performed to investigate the characteristics of human coronary thrombus in ST-segment...
Manual thrombus aspiration (TA) is effective to reduce the thrombus burden during primary percutaneous coronary intervention for ST-elevation myocardial infarction. The objective of this study is to a...
We report 2 similar cases of embolic myocardial infarction due to thrombus on a mechanical prosthesis despite anticoagulation therapy. In our first case, aspiration of the thrombus was performed succe...
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.
An episode of MYOCARDIAL ISCHEMIA that generally lasts longer than a transient anginal episode but that does not usually result in MYOCARDIAL INFARCTION.
A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).
Coagulation of blood in any of the CORONARY VESSELS. The presence of a blood clot (THROMBUS) often leads to 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.
