AIMS: Selective use of DES only in patients at higher risk of MACE is common practice, particularly in health care systems with a large premium payable for DES. We aimed to identify subgroups of patients in which the use of BMS in primary percutaneous coronary intervention (PPCI) for STEMI can still be justified. METHODS AND RESULTS: We performed a patient-level pooled analysis of COMFORTABLE-AMI and EXAMINATION comparing contemporary DES with BMS in PPCI. A risk score was applied using three parameters: lesion length>15mm, vessel size <3mm, and diabetes mellitus...

BACKGROUND: Chronic total occlusions remain one of the biggest challenges for interventional cardiologists and the high risk of restenosis and stent thrombosis is still a major problem. Drug-coated balloons showed favorable results for the treatment of in-stent restenosis and other lesion types. The aim of this study was to evaluate the feasibility and outcome of a drug-coated balloon only approach for chronic total occlusion. METHODS: We included 34 patients with a native chronic total occlusion treated only by drug-coated balloons...

BACKGROUND: Depressed heart rate variability (HRV) is usually considered a negative long-term prognostic factor after acute myocardial infarction. Anyway, most of the supporting research was conducted before the era of immediate reperfusion by percutaneous coronary intervention (PCI). Main aim of this study was to evaluate if HRV still retains prognostic significance in our era of immediate PCI. METHODS AND RESULTS: Two weeks after STEMI treated by primary PCI, time-domain HRV was assessed from 24-h Holter recordings in 186 patients: markedly depressed HRV (SDNN <70ms or <50ms) was present in 16% and in 5% of cases, respectively; patients with left ventricle ejection fraction (LVEF) <40% presented more often SDNN values in the lowest quartile...

The MARIA randomized trial evaluated the efficacy and safety of melatonin for the reduction of reperfusion injury in patients undergoing revascularization for ST-elevation myocardial infarction (STEMI). This was a prespecified interim analysis. A total of 146 patients presenting with STEMI within 6 hours of chest pain onset were randomized to receive intravenous and intracoronary melatonin (n=73) or placebo (n=73) during primary pecutaneous coronary intervention (PPCI). Primary endpoint was myocardial infarct size as assessed by magnetic resonance imaging (MRI) at 6±2 days...

Cocaine misuse is a known cause of acute coronary syndrome (ACS). Management of these patients has always been a challenge due to medication compliance and eventual risk of stent thrombosis. However, even cocaine misusers who are compliant with dual antiplatelet therapy have been reported to have stent thrombosis. All cases of cocaine-induced stent thrombosis reported in the literature have occurred within first year of stent placement (acute, subacute or late). We report a first case of very late stent thrombosis in a 54-year-old active cocaine misuser who presented with ST segment elevation myocardial infarction, which was successfully managed with percutaneous transluminal coronary angioplasty...

OBJECTIVES: Symptom-to-door time (S2D) is one of the important components of ischaemic time, which might affect the infarct size and outcomes of acute myocardial infarction. The aim of the present study was to identify patients' characteristics associated with delayed symptom-onset-to-arrival at EDs in ST-segment elevation myocardial infarction (STEMI) patients in Singapore. METHODS: Retrospective data of STEMI patients presenting to the ED of all public hospitals with onsite primary percutaneous coronary intervention facilities between 2010 and 2012 were obtained from the Singapore Myocardial Infarction Registry...

Drug-eluting balloons (DEB) may be considered as a "quiet revolution" in percutaneous coronary interventions. Early-generation DEB eluting paclitaxel proved to be very effective in animal models to reduce neointimal hyperplasia. Areas covered: Review of DEB efficacy in patients with coronary de novo lesions and in-stent restenosis (ISR). Expert opinion: Many randomized clinical trials and meta-analyses have demonstrated the value of DEB in patients with ISR. In this setting, DEB are safe and effective with clinical and angiographic results superior to plain balloon angioplasty and at least equivalent to first generation drug-eluting stents (DES)...

BACKGROUND: Restenosis after carotid endarterectomy (CEA) is associated with an increased risk of stroke, and the management of critical or symptomatic restenotic lesions poses a treatment challenge. The superiority of CEA vs carotid angioplasty and stenting (CAS) for restenosis remains debatable because existing studies are few and limited by small sample size or the inability to align interventions with ipsilateral events beyond the periprocedural period. We performed a population-based evaluation of CEA vs CAS in a large contemporary cohort of patients with carotid artery restenosis...

Wellens' syndrome is characterized by T-wave changes in electrocardiogram (EKG) during pain-free period in a patient with intermittent angina chest pain. It carries significant diagnostic and prognostic value because this syndrome represents a pre-infarction stage of coronary artery disease involving proximal left anterior descending (LAD) artery, which can subsequently lead to extensive anterior myocardial infarctions (MIs) and even death without coronary angioplasty. Therefore, it is crucial for every physician to recognize EKG features of Wellens' syndrome in order to take appropriate immediate intervention to reduce mortality and morbidity for MI...

BACKGROUND: FFR is routinely used to guide percutaneous coronary interventions (PCI). Visual assessment of the angiographic result after PCI has limited efficacy. Even when the angiographic result seems satisfactory FFR after a PCI might be useful for identifying patients with a suboptimal interventional result and higher risk for poor clinical outcome who might benefit from additional procedures. The aim of this meta-analysis was to investigate available data of studies that examined clinical outcomes of patients with impaired vs...

PURPOSE: Coronary angiography provides no details on underlying pathology in acute coronary syndromes (ACS). Optical coherence tomography (OCT) can visualize coronary atherosclerosis, thrombus formation, and plaque rupture in patients with myocardial infarction (MI) where coronary angiography is unclear. MATERIALS AND METHODS: We present a case series containing 6 young patients with ACS, 4 of them due to non-obstructive thrombus, in whom the operators refrained from stent implantation despite an identifiable culprit lesion with OCT-validated thrombus formation...

BACKGROUND: MicroRNAs (miRNAs) are key players in cardiovascular development and disease. However, not only miRNAs of a cardiac origin have a critical role in heart function. Recent studies have demonstrated that miR-122-5p, a hepatic miRNA, increases in the bloodstream during ischemic cardiogenic shock and it is upregulated in the infarcted myocardium. The aim of the present study was to determine the potential of circulating miR-122-5p as a biomarker for early prognostic stratification of ST-segment elevation acute myocardial infarction (STEMI) patients...

BACKGROUND: Currently available randomized data on the comparison between percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) for the treatment of unprotected left main coronary disease (LMD) lacks statistical power due to low numbers of patients enrolled. OBJECTIVES: This study assessed long-term outcomes of PCI and CABG for the treatment of LMD in specific subgroups according to disease anatomic complexity. METHODS: We conducted a pooled analysis of individual patient-level data of the LMD patients included in the PRECOMBAT (Bypass Surgery Versus Angioplasty Using Sirolimus-Eluting Stent in Patients With Left Main Coronary Artery Disease) and SYNTAX (Synergy Between PCI With TAXUS and Cardiac Surgery) trials...

Clopidogrel resistance from CYP2C19 polymorphism has been associated with stent thrombosis in patients undergoing percutaneous coronary intervention with drug-eluting stents. We present a case of a 76-year-old male who received drug-eluting stents to the right coronary artery and left anterior descending artery for non-ST elevation myocardial infarction and was discharged on dual antiplatelet therapy with aspirin and clopidogrel. He subsequently presented with chest pain from anterior, anteroseptal, and inferior ST segment elevation myocardial infarction...

Intracoronary thrombus is a common finding in acute coronary syndromes and often correlates with adverse prognosis and complications during percutaneous coronary interventions (PCIs). Bivalirudin, a direct thrombin inhibitor, is one of the recommended antithrombotic treatments for PCI in ST-elevation myocardial infarction (STEMI). The intracoronary administration of a bivalirudin loading dose, even if off-label, offers theoretical advantages over the standard intravenous route, providing a very high drug concentration in the infarct-related artery without increasing the total dose of the drug administered...

In the early days of coronary angioplasty, follow-up coronary angiography was often performed to assess restenosis. Angiographic restenosis has been shown to be associated with worse clinical outcomes, though the exact causality has yet to be determined. Numerous studies have repeatedly demonstrated that routine follow-up coronary angiography increases the incidence of target lesion revascularization without a clear reduction in mortality or myocardial infarction. Despite the lack of proven benefit of angiographic follow-up, routine follow-up coronary angiography is still being performed in certain countries and facilities...

OBJECTIVE: We hypothesised that, compared with culprit-only primary percutaneous coronary intervention (PCI), additional preventive PCI in selected patients with ST-elevation myocardial infarction with multivessel disease would not be associated with iatrogenic myocardial infarction, and would be associated with reductions in left ventricular (LV) volumes in the longer term. METHODS: In the preventive angioplasty in myocardial infarction trial (PRAMI; ISRCTN73028481), cardiac magnetic resonance (CMR) was prespecified in two centres and performed (median, IQR) 3 (1, 5) and 209 (189, 957) days after primary PCI...

OBJECTIVES: The aim of this study was to determine the prognostic impact of chronic total occlusion (CTO) on long-term mortality in a large prospective cohort. BACKGROUND: CTO is present in many patients with coronary artery disease and is difficult to treat with percutaneous coronary intervention. METHODS: The study population consisted of all consecutive patients who underwent coronary angiography in Sweden between January 1, 2005 and January 1, 2012, who were registered in SCAAR (Swedish Coronary Angiography and Angioplasty Registry)...
