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 myocardial infarction compared to conventional percutaneous coronary intervention (PCI).
The Thrombus Aspiration during Percutaneous coronary intervention in Acute myocardial infarction Study (TAPAS) has shown that thrombus aspiration improves myocardial perfusion and clinical outcome compared to conventional primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction. Impaired myocardial perfusion due to spontaneous or angioplasty-induced embolization of atherothrombotic material also occurs in patients with Non-ST-elevation myocardial infarction (NSTEMI). The aim of this study is to determine whether thrombus aspiration before stent implantation will result in improved myocardial perfusion in patients with NSTEMI compared to conventional PCI.
The study is a single-centre, prospective, randomised trial with blinded evaluation of endpoints. The planned inclusion is 540 patients with acute NSTEMI who are candidates for urgent PCI.
If thrombus aspiration leads to significant improvement of myocardial perfusion in patients with acute NSTEMI it may become part of the standard interventional approach.

Although successful, percutaneous coronary interventions (PCI) with stent implantation may be hampered by periprocedural myocardial necrosis. In acute ST-elevation myocardial infarction (S...
This is a prospective, randomized study with blinded outcome assessment, comparing routine manual thrombus aspiration with no aspiration in patients with acute ST-segment elevation myocard...
This is a randomized, double blind, placebo controlled study of intracoronary cocktail injection combined with thrombus aspiration versus thrombus aspiration alone in ST-elevation myocardi...
In patients with acute ST-segment elevation myocardial infarction (STEMI), percutaneous coronary intervention (PCI) may cause thrombus dislodgment and impaired microcirculatory reperfusion...
Thirty patients with acute ST-elevation myocardial infarction treated with primary PCI and aspiration of thrombus material from the infarct related coronary artery will be included. Both c...
We aimed to investigate the determinants of thrombus burden (TB) and the impact of thrombus aspiration (TA) on outcome in young adults with ST segment elevation myocardial infarction (STEMI).
Prasugrel was shown to inhibit platelet activity more rapidly and consistently than clopidogrel. We compared the effects of prasugrel and clopidogrel on residual thrombus burden assessed by optical co...
BACKGROUND The aim of this study was to investigate the optimal route of administration of diltiazem in emergency PCI and to provide the best clinical treatment for ASTEMI patients. MATERIAL AND METHO...
Use of a BRS either in clinical practice or in the setting of an acute myocardial infarction (MI) is controversial. Despite an overall high rate of thrombosis, vascular healing response following BRS ...
First pass complete (mTICI 3) reperfusion must be regarded as the ultimate goal in mechanical thrombectomy (MT) in patients suffering from an emergent large vessel occlusion (ELVO). With this in mind...
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).
Postoperative hemorrhage from an endovascular AORTIC ANEURYSM repaired with endoluminal placement of stent grafts (BLOOD VESSEL PROSTHESIS IMPLANTATION). It is associated with pressurization, expansion, and eventual rupture of the aneurysm.
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).
A type of lung inflammation resulting from the aspiration of food, liquid, or gastric contents into the upper RESPIRATORY TRACT.
A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called angioplasty. &...
