[Renal denervation for treatment of arterial hypertension - the unanswered questions].

Despite the extensive armamentarium of antihypertensive medication available, the control of hypertension remains poor. Therefore any possibilities of non-pharmacological treatment of resistant hypertension are welcome. Recently, close attention was paid to renal denervation.

ST-segment elevation myocardial infarction treated by radial or femoral approach in a multicenter randomized clinical trial: the STEMI-RADIAL trial.

Objectives: This study sought to compare radial and femoral approaches in patients presenting with ST-segment elevation myocardial infarction (STEMI) and undergoing primary percutaneous coronary intervention (PCI) by high-volume operators experienced in both access sites.

Background: The exact clinical benefit of the radial compared to the femoral approach remains controversial.

Methods: STEMI-RADIAL (ST Elevation Myocardial Infarction treated by RADIAL or femoral approach) was a randomized, multicenter trial.

Early and late outcomes after primary percutaneous coronary intervention by radial or femoral approach in patients presenting in acute ST-elevation myocardial infarction and cardiogenic shock.

Background: Although radial approach is increasingly used in percutaneous coronary interventions (PCIs) including in acute myocardial infarction (MI), patients with cardiogenic shock have been excluded from comparisons with femoral approach. The aim of our study was to compare clinical outcomes in patients undergoing primary PCI with cardiogenic shock by radial and femoral approach.

Methods And Results: From 2,663 patients presenting with ST-elevation MI in 2 large volume radial centers, we identified 197 patients (7.

Efficacy and safety of transient ulnar artery compression to recanalize acute radial artery occlusion after transradial catheterization.

Radial artery occlusion (RAO) can result from transradial catheterization. We compared the incidence of RAO with 2 heparin dosage regimens after transradial coronary angiography, and we evaluated the efficacy and safety of transient homolateral ulnar artery compression to achieve acute radial artery recanalization. Patients referred for coronary angiography were randomized to very-low-dose heparin (2,000 IU) or low-dose heparin (5,000 IU).
