OBJECTIVES: The aims of the study were to assess the prognostic significance of cardiac magnetic resonance myocardial feature tracking (CMR-FT) in a large multicenter study and to evaluate the most potent CMR-FT predictor of hard clinical events following myocardial infarction (MI). BACKGROUND: CMR-FT is a new method that allows accurate assessment of global and regional circumferential, radial, and longitudinal myocardial strain. The prognostic value of CMR-FT in patients with reperfused MI is unknown...

BACKGROUND: The potential interactions between prehospital (pre-H) ticagrelor administration and thrombus aspiration (TA) in patients with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI) have never been studied. Therefore, we evaluated the potential benefit of TA and pre-H ticagrelor treatment in patients enrolled in the ATLANTIC trial (NCT01347580). METHODS: This analysis included 1,630 patients who underwent primary PCI...

Although routine aspiration thrombectomy (AT) is not recommended by the current American College of Cardiology/American Heart Association/Society for Cardiovascular Angiography and Interventions guideline, for selected cases, a class IIb indication is given because of lack of data. We studied the impact of selective AT on mortality in patients with ST-segment elevation myocardial infarction using a prospective registry. We analyzed data of 1,255 patients, of whom 535 underwent AT based on operator's decision...

The use of thrombus aspiration (TA) prior to primary percutaneous coronary intervention (PPCI) has undergone a radical change in intervention guidelines. The clinical implications, however, are still under scrutiny. This study investigated the clinical effects and outcome of TA before PPCI in patients with ST-segment elevation myocardial infarction (STEMI). Overall 1027 patients with STEMI were analyzed in this retrospective, propensity score-adjusted, multicenter study. The primary endpoints were in-hospital and long-term mortality...

BACKGROUND AND AIMS: Recent studies have shown that coronary thrombus histopathology is associated with impaired myocardial reperfusion and poor clinical outcome in patients with acute myocardial infarction (AMI). We sought to investigate the age of thrombi aspirated during percutaneous coronary intervention (PCI) in patients with AMI and evaluate the relationship between histopathologic findings and major adverse cardiac and cerebrovascular events (MACCEs) defined as all-cause death, stroke, or myocardial infarction within 6 months of PCI...

BACKGROUND: The clinical benefit of manual thrombus aspiration (TA) during primary percutaneous coronary intervention (PPCI) in patients with ST-segment elevation myocardial infarction (STEMI) remains uncertain. This study assessed the impact of circadian rhythms on the effectiveness of manual TA. METHODS AND RESULTS: We conducted an observational study of patients enrolled in the Acute Myocardial Infarction in Switzerland Plus registry. STEMI patients undergoing PPCI with (TA group) or without (PCI-alone group) manual TA were divided based on time-of-day symptom onset: group 1 (00:00-05:59), group 2 (06:00-11:59), group 3 (12:00-17:59) and group 4 (18:00-23:59)...

This article gives an update on the management of acute ST-segment elevation myocardial infarction (STEMI) according to the recently released European Society of Cardiology guidelines 2017 and the modifications are compared to the previous STEMI guidelines from 2012. Primary percutaneous coronary intervention (PCI) remains the preferred reperfusion strategy. New guideline recommendations relate to the access site with a clear preference for the radial artery, use of drug-eluting stents over bare metal stents, complete revascularization during the index hospitalization, and avoidance of routine thrombus aspiration...

OBJECTIVE: ECG ST segment resolution (STR) has been used to assess myocardial perfusion in STEMI patients undergoing PPCI. However, in most of the studies ECGs recorded at different time points after the actual procedure have been used, limiting the options of therapeutic interventions while the patient is still in the catheterisation laboratory. The aim of this study was to investigate the presence and clinical consequences of intra-procedural STR during PPCI. METHODS: We analysed 12 lead ECGs recorded at the onset and the end of the PPCI procedure, measuring STR in the lead with maximum ST elevation on the initial recording...

BACKGROUND: Manual thrombus aspiration and local drug delivery of abciximab have been proposed as a strategy to reduce thrombus burden during percutaneous coronary intervention in patients with ST elevation myocardial infarction; however, the effectiveness of these approaches, is uncertain. In this COCTAIL II substudy, we compared the effect of these strategies on prestenting and poststenting thrombus burden assessed by optical coherence tomography. PATIENTS AND METHODS: COCTAIL II trial enrolled patients with ST elevation myocardial infarction randomized to intralesion (IL, by the ClearWay catheter) versus intracoronary (IC, by the guide catheter) abciximab bolus with or without aspiration thrombectomy (AT)...

Simple mechanical reperfusion (SMR) is defined as reperfusion achieved after wire insertion at the occluded infarct-related artery in primary angioplasty. The determinants and prognostic implications of SMR and its relationship with the histopathology of the rescued thrombus were evaluated in 601 patients with acute myocardial infarction showing ST elevation and pre-procedural total occlusion of the infarct-related artery (TIMI flow 0). Two groups were considered according to the presence of SMR, defined as the visualization of contrast material after crossing the occlusion with the guide wire...

The role of manual thrombus aspiration (TA) during primary percutaneous coronary intervention (PPCI) for acute ST-segment-elevation myocardial infarction has been a matter of intense research and debate now. Although recent randomized controlled clinical trials (notably TASTE [Thrombus Aspiration in ST-Elevation Myocardial Infarction in Scandinavia] and TOTAL [Trial of Routine Aspiration Thrombectomy With PCI Versus PCI Alone in Patients With STEMI]) do not supply evidence supporting the routine use of TA in patients with ST-segment-elevation myocardial infarction, manual TA remains a therapeutic option for interventional cardiologists when treating patients with substantial thrombus burden during PPCI...

BACKGROUND: The alarmin family member myeloid-related protein (MRP)-14 (S100A9), which has been identified by platelet transcriptional profiling as an acute myocardial infarction gene, regulates vascular inflammation and thrombosis. Elevated plasma levels of MRP-8/14 (S100A8/A9) heterodimer predict first and recurrent cardiovascular events. The aim of this study was to elucidate pathophysiological roles of MRP-8/14 in acute coronary syndrome (ACS). METHODS AND RESULTS: In 38 consecutive ACS patients, the MRP-8/14 level in coronary artery blood obtained at thrombus aspiration was higher in 23 patients, in whom aspirated thrombus was confirmed, compared to the 15 patients, in whom it was absent [4...
