Gender differences in risk factor management and pharmacological treatment among CHD patients: Belgian results of the EUROASPIRE IV and EUROASPIRE V surveys.

Aims: The aim of this study was to provide an up-to-date overview of gender differences or similarities in risk factor control and medical management in the Belgian CHD population.

Methods: All analyses are based on the ESC EORP EUROASPIRE IV and EUROASPIRE V (European Survey Of Cardiovascular Disease Prevention And Diabetes) surveys. Patients between 18 and 80 years old, hospitalised for a first or recurrent coronary event, were included in the survey.

Prevalence and Disease Spectrum of Extracoronary Arterial Abnormalities in Spontaneous Coronary Artery Dissection.

Importance: Spontaneous coronary artery dissection (SCAD) has been associated with fibromuscular dysplasia (FMD) and other extracoronary arterial abnormalities. However, the prevalence, severity, and clinical relevance of these abnormalities remain unclear.

Objective: To assess the prevalence and spectrum of FMD and other extracoronary arterial abnormalities in patients with SCAD vs controls.

Reduction of Lipid-Core Burden Index in Nonculprit Lesions at Follow-Up after ST-Elevation Myocardial Infarction: A Randomized Study of Bioresorbable Vascular Scaffold versus Optimal Medical Therapy.

Background: Non-flow-limiting nonculprit lesions (NCL) that contain a large lipid-rich necrotic core (nonculprit lipid-rich plaques (NC-LRP)) are most likely to cause recurrent acute coronary syndrome after ST-elevation myocardial infarction (STEMI). Near-infrared spectroscopy (NIRS) detects LRPs using the maximum 4 mm lipid-core burden index (maxLCBI). Few data are available regarding NIRS-guided therapy of these NC-LRPs, which are a potential target for preventive stenting.

Usefulness of a Gentle and Short Hemostasis Using the Transradial Band Device after Transradial Access for Percutaneous Coronary Angiography and Interventions to Reduce the Radial Artery Occlusion Rate (from the Prospective and Randomized CRASOC I, II, and III Studies).

The study sought to evaluate the benefit of the reduction in intensity and duration of the hemostasis obtained with the transradial (TR) Band compression device on the radial artery occlusion (RAO) rate. RAO is the most frequent complication of TR access for cardiac catheterization and limits future use of this safe route. Its occurrence must be minimized.

The STIB score: a simple clinical test to predict clopidogrel resistance.

Background: High platelet reactivity (HPR) to clopidogrel is associated with an increased risk of ischaemic complications during and after coronary interventions and concerns up to 50% of patients undergoing PCI.

Aim Of The Study: The aim of the study was to identify patients with HPR to clopidogrel using bedside clinical information obtained in the Stent Thrombosis In Belgium (STIB) trial.

Methods: Data on platelet reactivity using the VerifyNow® point-of-care assay were obtained in 844 patients undergoing PCI for stable coronary artery disease 12 to 24 hours after a 600-mg loading dose of clopidogrel was given.

Long-term effect of molsidomine, a direct nitric oxide donor, as an add-on treatment, on endothelial dysfunction in patients with stable angina pectoris undergoing percutaneous coronary intervention: results of the MEDCOR trial.

Objective: The MEDCOR trial is a double-blind, randomized study aiming at demonstrating the superiority of molsidomine (direct NO donor) over placebo, used as add-on treatments, on improving endothelial function (EF) after 12 months, in stable angina patients undergoing percutaneous coronary intervention.

Methods: EF was assessed by peripheral vasodilator response (i.e.

Platelet reactivity and cardiovascular events after percutaneous coronary intervention in patients with stable coronary artery disease: the Stent Thrombosis In Belgium (STIB) trial.

Aims: The Stent Thrombosis In Belgium (STIB) trial aimed to determine whether assessing platelet reactivity (PR) in patients with stable coronary artery disease undergoing elective percutaneous coronary intervention (PCI) could predict the risk of ischaemic complications and adverse clinical events up to 30 days post PCI.

Methods And Results: PR before intervention was determined in 891 patients undergoing PCI for stable angina pectoris. Twelve to 24 hours before PCI, all patients received a 600 mg clopidogrel dose followed by 75 mg daily, and 500 mg of aspirin followed by 80-100 mg daily.

Impact of frailty scores on outcome of octogenarian patients undergoing transcatheter aortic valve implantation.

Background: For selected patients with symptomatic aortic stenosis, transcatheter aortic valve implantation (TAVI) is an alternative to surgical aortic valve replacement (AVR). In addition to co-morbidities, frailty has to be taken into account in the decision-making process. Criteria for patient selection, according to current guidelines, include EuroSCORE and STS score but frailty is not easy to quantify.

Double-blind parallel placebo-controlled study to evaluate the effect of molsidomine on the endothelial dysfunction in patients with stable angina pectoris undergoing percutaneous coronary intervention: the MEDCOR Trial.

The effects of molsidomine (a direct nitric oxide donor) on the endothelial dysfunction have never been evaluated using reactive hyperemia peripheral arterial tonometry (RH-PAT). The objective of the MEDCOR double-blind trial will be to demonstrate the superiority of molsidomine (Coruno® 16 mg, once daily) over placebo, on improving the endothelial function (Endoscore by RH-PAT) after 12 months of treatment in stable angina patients undergoing elective percutaneous coronary intervention (PCI). Study design will take care of the real-life situation, in which patients are being offered PCI and stent placement (drug-eluting or bare metal), but also gold standard medical therapy (beta-blockers, statins, angiotensin-converting enzyme inhibitors (ACEIs), and/or calcium antagonists).

Full conversion from transfemoral to transradial approach for percutaneous coronary interventions results in a similar success rate and a rapid reduction of in-hospital cardiac and vascular major events.

Aims: The transradial approach (TRA) for percutaneous coronary intervention (PCI) recently emerged as a safer vascular access with a similar rate of MACE but a lower success rate requiring crossover to another approach when compared to the transfemoral approach (TFA).

Methods And Results: In our hospital the introduction of the TRA in November 2003 resulted in a progressive decline of TFA use. Over the five years of conversion to TRA, from 2002 (100% TFA) to 2007 (98% TRA), major adverse cardiac events (MACE) and all in-hospital vascular and bleeding events, related or not to vascular access, were prospectively collected to assess performances of each approach in the specific setting of PCI (percutaneous coronary interventions).

Recovery after balloon aortic valvuloplasty in patients with aortic stenosis and impaired left ventricular function: predictors and prognostic implications.

Aims: The aim of this study was to evaluate predictors of recovery after balloon aortic valvuloplasty (BAV) among patients with aortic stenosis and depressed left ventricular ejection fraction (LVEF). Predictors for recovery after BAV are not clearly defined. B-type natriuretic peptide (BNP) predicts outcome after surgical and transcatheter aortic valve replacement.

The different mechanisms of periprocedural myocardial infarction and their impact on in-hospital outcome.

Background: CK-MB levels exceeding 3 times the upper limit of normal (ULN) following percutaneous coronary intervention (PCI), defining periprocedural myocardial infarction (PMI), are associated with worse outcomes. This study assessed the incidence and mechanisms of PMI and their impact on in-hospital stay.

Methods And Results: Over a 12-year period (1996-2007), 272 cases of PMI (overall incidence, 3.

Low rate of conversion to transfemoral approach when attempting both radial arteries for coronary angiography and percutaneous coronary intervention: a study of 1,826 consecutive procedures.

Aims: Despite a proven safety profile, the transradial approach (TRA) for coronary procedures is regarded by many as complicated and the second-choice arterial access, with a high conversion rate to transfemoral access (TFA). This study reports causes of failure and the contemporary success rate of TRA when both radial arteries are attempted first before converting to TFA.

Methods: This prospective, single-center study included 1,826 consecutive patients referred for cardiac catheterization, which was performed by two trained operators between January 2005 and June 2007.
