Impact of Midregional N‐Terminal Pro–Atrial Natriuretic Peptide and Soluble Suppression of Tumorigenicity 2 Levels on Heart Rhythm in Patients Treated With Catheter Ablation for Atrial Fibrillation: The Biorhythm Study
Background We assessed the impact of preprocedural plasma levels of MRproANP (midregional N‐terminal pro–atrial natriuretic peptide) and sST2 (soluble suppression of tumorigenicity 2) on recurrence of atrial fibrillation (AF) at 1 year after catheter ablation of AF. Methods and Results This was a prospective, multicenter, observational study including patients undergoing catheter ablation of AF. MRproANP and sST2 were measured in a peripheral venous blood preprocedure, and MRproANP was assessed in the right and left atrial blood during ablation. The primary end point was recurrent AF between 3 and 12 months postablation, defined as a documented (>30 seconds) episode of AF, flutter, or a…
Pravastatin reverses the membrane cholesterol reorganization induced by myocardial infarction within lipid rafts in CD14(+)/CD16(-) circulating monocytes.
International audience; Large numbers of monocytes are recruited in the infarcted myocardium. Their cell membranes contain cholesterol-rich microdomains called lipids rafts, which participate in numerous signaling cascades. In addition to its cholesterol-lowering effect, pravastatin has several pleiotropic effects and is widely used as secondary prevention treatment after myocardial infarction (MI). The aim of this study was to investigate the effects of pravastatin on the organization of cholesterol within monocyte membrane rafts from patients who had suffered myocardial infarction. Monocytes from healthy donors and acute MI patients were cultured with or without 4μM pravastatin. Lipid raf…
End-of-life situations in cardiology: a qualitative study of physicians' and nurses' experience in a large university hospital.
IF 2.335 (2-year Impact Factor); International audience; Background: rofessional societies call for integration of end-of-life discussions early in the trajectory of heart failure, yet it remains unclear where current practices stand in relation to these recommendations. We sought to describe the perceptions and attitudes of caregivers in cardiology regarding end-of-life situations.Methods: e performed a qualitative study using semi-directive interviews in the cardiology department of a university teaching hospital in France. Physicians, nurses and nurses’ aides working full-time in the department at the time of the study were eligible. Participants were asked to describe how they experienc…
Combination Therapy with Oral Treprostinil for Pulmonary Arterial Hypertension:A Double-Blind Placebo-controlled Clinical Trial
Rationale: Oral treprostinil improves exercise capacity in patients with pulmonary arterial hypertension (PAH), but the effect on clinical outcomes was unknown.\ud \ud Objectives: To evaluate the effect of oral treprostinil compared with placebo on time to first adjudicated clinical worsening event in participants with PAH who recently began approved oral monotherapy.\ud \ud Methods: In this event-driven, double-blind study, we randomly allocated 690 participants (1:1 ratio) with PAH to receive placebo or oral treprostinil extended-release tablets three times daily. Eligible participants were using approved oral monotherapy for over 30 days before randomization and had a 6-minute-walk dista…
