Trial launched to assess 320-slice CT ability to detect CAD
An international study on CT perfusion imaging at 15 medical centers in eight countries, led by researchers at Johns Hopkins University in Baltimore, have enrolled the first dozen patients to figure out how well various imaging tests can measure the degree of blockage or narrowing in any particular artery and their use in predicting patients who need catheterization or angioplasty, or bypass surgery.

Triple Therapy: Triple Safety or Triple Danger?
We read the report by Zinn and Feit with great interest. We learned from the article by Zinn and Feit to individualize care and tailor therapy according to the risk for bleeding but also to ischemic and embolic complications. Zinn and Feit state that all data were retrospective and that most came from single-center series. A randomized trial with head-to-head assessment of differing antithrombotic regimens is needed. Zinn and Feit state that there are no randomized trials prospectively addressing a comparison of triple therapy and dual-antiplatelet therapy to guide clinical decision making. In patients with indication for long-term oral anticoagulation (OAC) who need to undergo percutaneous coronary intervention, there are theoretically 4 possibilities: the combinations of aspirin plus clo......

Patient radiation doses in the most common interventional cardiology procedures in Croatia: first results
Apart from its benefits, the interventional cardiology (IC) is known to generate high radiation doses to patients and medical staff involved. The European Union Medical Exposures Directive 97/43/Euroatom strongly recommend patient dosimetry in interventional radiology, including IC. IC patient radiation doses in four representative IC rooms in Croatia were investigated. Setting reference levels for these procedures have difficulties due to the large difference in procedure complexity. Nevertheless, it is important that some guideline values are available as a benchmark to guide the operators during these potentially high-dose procedures. Local and national diagnostic reference levels (DRLs) were proposed as a guidance. A total of 138 diagnostic (coronary angiography, CA) and 151 therapeuti......

Review Article: Examining Treatment of ST-Elevation Myocardial Infarction: The Importance of Early Intervention
Early reperfusion in ST-segment elevation myocardial infarction (STEMI) is imperative. Acute reperfusion may be achieved with fibrinolytic agents and/or percutaneous coronary intervention (PCI); however, PCI is associated with lower rates of death and myocardial infarction compared with fibrinolysis. As treatment delays are associated with worse outcomes, current guidelines recommend minimizing time from symptom onset to treatment initiation. Regardless of the reperfusion strategy, patients with STEMI are at increased risk of early recurrent ischemic events and death. These risks can be significantly reduced by promptly initiating a combination of pharmacotherapies that includes antiplatelet and anticoagulant agents, β-blockers, and inhibitors of the renin-angiotensin-aldosterone syst......

In Diabetics, Revascularization More Likely After PCI Vs CABG
For patients with diabetes and complex multivessel coronary artery disease, the risk of repeat vascularization within one year is elevated 3-fold after percutaneous coronary intervention (PCI) compared with surgery, according to a subgroup analysis from the multinational SYNTAX study.

Novel Polymeric Coatings with the Potential to Control In-stent Restenosis -- An In Vitro Study
This study evaluates the influence of polymer coatings on human aortic endothelial cells (HAEC) and coronary artery smooth muscle cells (HCASMC) in vitro, in terms of morphology, cell number, and phenotype. It was demonstrated that the polymer coatings can be tailored to enhance adhesion and growth of HAECs whilst suppressing that of HCASMCs. It is concluded that one of the polymer coatings (BTL 01015) shows potential as a stent coating to enhance re-endothelialization. (Source: Journal of Biomaterials Applications)...

Infarct size and left ventricular function in the PRoximal Embolic Protection in Acute myocardial infarction and Resolution of ST-segment Elevation (PREPARE) trial: ancillary cardiovascular magnetic resonance study
Conclusions
Primary PCI with combined proximal embolic protection and thrombus aspiration in STEMI patients did not result in significant differences in final infarct size or left ventricular function at follow-up CMR. In addition, there was no difference in the incidence of major adverse cardiac and cerebral events at 6 months.

Complications of Angioplasty and Stenting of Cervicocerebral Arteries in Iran [ORIGINAL ARTICLE]
Angioplasty and stenting of the cervicocerebral arteries is a novel treatment for atherosclerotic stenosis, which has periprocedural complications. Data were collected prospectively from 2007 to 2009 in a multicenter cohort of patients undergoing interventions for cervicocerebral stenosis. Retrospective assessment of the 2003–2006 archives of the same interventionists and a review of their published work is the second part of this national survey. In 592 extracranial internal carotid artery angioplasty and stenting procedures in 581 patients (73% male; mean age, 63.4 ± 7 years), transient ischemic attack, stroke, intracerebral hemorrhage, and death occurred in 1.7%, 1.7%, 0.34%, and 1.52%, respectively. In 114 extracranial vertebral artery angioplasty and stenting procedures i......

Right Ventricular Function Suffers From Reperfusion Delay: Tissue Doppler Study
In this study, impact of reperfusion delay on adverse cardiac events and right ventricular (RV) function in patients with acute right ventricular myocardial infarction (RVMI) was assessed. In 70 patients with RVMI, RV function was assessed by M-mode tricuspid annular plane systolic excursion (TAPSE) and by pulsed wave tissue Doppler echocardiography (TDE). Right ventricular early (E[prime]T) and late diastolic (A[prime]T), peak systolic tricuspid annular velocity, (S[prime]T) and right ventricular myocardial performance index (RVMPI) were measured. Patients were divided into 2 groups according to the time between the onset of symptoms and percutaneous transluminal coronary angioplasty (PTCA) - group 1 (n = 25), [le]3 hours and group 2 (n = 45), > 3 hours. During 30-day follow-up, we assess......

Prevention of Contrast-induced Nephropathy: A Single Center Randomized Study
Contrast-induced nephropathy (CIN) is the third cause of acute deterioration of renal function in hospitalized patients.The purpose of the study was to compare the efficacy of saline infusion, saline infusion plus N-acetylcysteine (NAC), and sodium bicarbonate (SB) infusion to prevent CIN in patients undergoing coronary angiography and/or percutaneous coronary intervention.We prospectively studied 156 patients with a baseline creatinine level [ge] 1.2 mg/dL. The primary endpoint was the development of CIN, defined as an increase in serum creatinine concentration [ge] 25% over the baseline value within 5 days from contrast exposure.Contrast-induced nephropathy developed in 23 patients (14.7%). Incidence of the primary endpoint was similar in the 3 groups of treatment, occurring in 7 patient......

Impact of genetic variation on cardiovascular outcomes in clopidogrel-treated patients with PCI
Source: Circulation
Area: News
Recent research has suggested that the CYP2C19*17 allelic variant is associated with increased transcriptional activity, leading to extensive metabolisation of CYP2C19 substrates, which may lead to an enhanced platelet response to clopidogrel treatment. To investigate this further, this study assessed the impact of CYP2C19*17 on ADP-induced platelet aggregation, the risk of bleeding, and stent thrombosis in clopidogrel-treated patients undergoing percutaneous coronary intervention (PCI).
Study investigators enrolled 1524 patients undergoing PCI after pre-treatment with a loading dose of 600 mg clopidogrel. The primary safety end point was the 30-day incidence of bleeding defined according to Thrombolysis in Myocardial Infarction (TIMI) criteria, a......

Invited commentary
This article is important, because the transition to endovascular-first treatment for CMI is not limited to this group but has been observed in many vascular practices. This report highlights the continued tradeoff of newer, less invasive treatments, and lower morbidity at the expense of durability and higher reintervention rates compared with open surgery.
