BACKGROUND AND AIM: It was hypothesized that the pattern of coronary occlusion (thrombus composition) might contribute to the onset of ventricular arrhythmia and sudden cardiac death (SCD) in myocardial infarction (MI). METHODS: The TIDE (thrombus and inflammation in sudden death) study included patients with angiographically-proven acute coronary occlusion as the cause of a ST elevation MI (STEMI) complicated by Sudden Cardiac Death (SCD group) or not (STEMI group)...

BACKGROUND: Blunt cardiac trauma encompasses a wide range of clinical entities, including myocardial contusion, cardiac rupture, valve avulsion, pericardial injuries, arrhythmia, and even myocardial infarction. Acute myocardial infarction due to coronary artery dissection after blunt chest trauma is rare and may be life threatening. Differential diagnosis of acute myocardial infarction from cardiac contusion at this setting is not easy. CASE PRESENTATION: Here we demonstrated a case of blunt chest trauma, with computed tomography detected myocardium enhancement defect early at emergency department...

RATIONALE: Coronary artery ectasia (CAE) is characterized by an abnormal dilatation of the coronary arteries. CAE is often associated with the presence of slow coronary flow and may lead to acute myocardial infarction (AMI), even without total occlusion. PATIENT CONCERNS AND DIAGNOSIS: We report a case of a 24-year-old male patient with CAE suffering from AMI. INTERVENTIONS: Percutaneous coronary intervention with aspiration thrombectomy failed to restore adequate blood flow...

BACKGROUND Acute myocardial infarction (AMI) can be caused not only by plaque rupture/erosion, but also by many other mechanisms. Thromboembolism due to atrial fibrillation and coronary thrombosis due to coronary artery ectasia are among the causes. Here we report on a case of recurrent myocardial infarction with coronary artery ectasia. CASE REPORT Our case was a 78-year-old woman with hypertension. Within a one-month interval, she developed AMI twice at the distal portion of her right coronary artery along with coronary artery ectasia...

BACKGROUND: ST-elevation myocardial infarction (STEMI) is typically caused by an occlusive coronary thrombus. The process of intracoronary thrombus formation is poorly understood. It is known that inflammatory cells play a role in the formation and resolution of venous thrombi, however their role in coronary thrombosis is not clear. We therefore analyzed inflammatory cells in thrombi derived from patients with STEMI in relation to histologically classified thrombus age. METHODS: Thrombus aspirates of 113 patients treated with primary percutaneous coronary intervention were prospectively collected and classified (fresh, lytic, or organized) based on hematoxylin and eosin staining...

A 62-year-old man with a family history of coronary artery disease and a history of smoking, diabetes and dyslipidemia was admitted to our hospital with chest pain from acute myocardial infarction. Emergent coronary angiography was performed with intervention to a mid-right coronary occlusion with drug-eluting stent implantation. Optical coherence tomography (OCT) visualized well-apposed stent struts and no remarkable tissue protrusion, stent underexpansion, malapposition, edge dissection, and hematoma. Immediately after OCT imaging, a coronary angiogram showed a filling defect surrounded by contrast medium at the site of the stented lesion...

OBJECTIVES: The aim of this study was to evaluate if residual thrombus burden after aspiration thrombectomy affects the outcomes of primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction (STEMI). BACKGROUND: Recent studies failed to show clinical benefit of aspiration thrombectomy in STEMI patients. This might be due to insufficient removal of thrombus at the culprit lesion. METHODS: A total of 109 STEMI patients who underwent aspiration thrombectomy followed by stenting within 24 h from symptom onset were included...

BACKGROUND: Massive intracoronary thrombus is associated with adverse procedural results including failed aspiration and unfavourable reperfusion. We aim to evaluate the effect of the intracoronary administration of antithrombotic agents via a perfusion catheter in patients with ST-segment elevation myocardial infarction (STEMI) presenting with a large thrombus burden and failed aspiration. METHODS: We retrospectively analyzed the thrombus burden, the TIMI grade flow, and the myocardial Blush in 25 consecutive STEMI patients with a large thrombus burden and failed manual aspiration, who received intracoronary infusion of glycoprotein IIb/IIIa inhibitors (N=17) or bivalirudine (N=8) via a 6F-infusion catheter (ClearWay™ RX) RESULTS: Mean age was 67±14 years, 16 patients (64 %) presented with anterior STEMI, and 7 (28 %) with cardiogenic shock...

Recent advances have caused a major shift in the way ST-elevation myocardial infarctions are managed. This review explores the pharmacological and interventional techniques that have evidence for improving outcomes and the landmark trials that have sparked change. The new P2Y12 inhibitors, ticagrelor and prasugrel, have been shown to be superior to clopidogrel in STEMI patients undergoing primary percutaneous coronary intervention. Concurrently, many technical aspects of percutaneous coronary intervention have been further clarified by trial data, with bare-metal stents, routine thrombus aspiration and femoral access showing evidence of inferiority...
