Filter by:Atrial fibrillation (AF) is the most common clinical arrhythmia. AF is associated with increased risk for stroke due to blood clots formed in the fibrillating atria. Some patient characteristics increase the likelyhood of AF and at the same time the risk of stroke when AF has developed. To reduce the risk of stroke, anticoagulation therapy is recommended in patients with AF and risk factors (such as high blood pressure, diabetes, vessel disease). However, occasional (paroxysmal) AF may occur without symptoms and remain undetected, leaving patients at risk. Aim of the prospective randomized study is to compare two management strategies for patients at increased risk for AF but without a known history of AF. Patients are seen regularly (monthly, then quarterly) for follow-up (incl. ECG recording and blood sample). One group of patients additionally receives a subcutaneous implantation of a loop recorder for continuous rhythm monitoring, while the control group remains on standard follow-up. Observation period is one year (optional extension for 3 years). The time to first diagnosis of AF is compared between groups, blood samples are analyzed for potential biomarkers of AF.
This study proposes to assess the effect of the standard of care, which is continuation of the pre op beta blocker dose into the post operative period compared to the administration of esmolol titrated to a pre determined target HR. The primary outcome will compare postoperative plasma levels of metoprolol in 2 cohorts in a group who has been continued on metoprolol (administrated via a nasogastric tube in NPO patients) to a group who has been withdrawn from metoprolol but given an esmolol infusion titrated to HR. Secondary outcomes will compare a) the hemodynamic responses, documenting the incidence of unplanned hypotension and bradycardia and b) to compare the effects of Heart rate to the incidence of myocardial ischemia, arrhythmias, delirium and infarction.
The purpose of this study is to analyze genetic polymorphisms in genes encoding pro-inflammatory cytokines, and study the genetic predisposition to chronic periodontitis (CP) in combination with atherosclerotic cardiovascular (ACD) and aneurysmal diseases. The investigators will also try to identify oral bacteria in atherosclerotic plaques and aneurysmal walls and thrombus. Histological analyses of atherosclerotic plaques and aneurysmal wall will be performed.
This is a clinical study of a new self-expanding stent (FlexStent®) designed specifically to cope with the extreme demands of the superficial femoral artery (SFA)/proximal popliteal artery. The arteries are often abbreviated as femoropopliteal. The intent of this study is to demonstrate that the FlexStent® Femoropopliteal Self-Expanding Stent System is safe and effective for the treatment of patients with peripheral arterial disease. Specifically, the FlexStent® shall meet or exceed the proposed safety and efficacy performance goals established for Femoropopliteal bare nitinol stents in patients with symptomatic peripheral arterial disease.
This is a prospective, observational, single-arm, open-label, multicenter, postapproval registry study in China. The purpose of this study is to: - Evaluate the continued safety and effectiveness of the XIENCE V EECSS in a cohort of real-world patients receiving the XIENCE V EECSS during commercial use - Evaluate patient compliance to dual antiplatelet therapy (DAPT)
An abdominal aortic aneurysm (AAA) is a weakened and enlarged area in the abdominal aorta, which is a large blood vessel in the abdomen. Large AAAs (>55 mm diameter) carry a high risk of rupture, a surgical emergency that often leads to death due to severe internal bleeding. It has been suggested that regular exercise training might limit the rate at which AAAs develop. However, little is known about the safety and effectiveness of exercise training in these patients. This pilot study will examine the feasibility of supervised aerobic exercise training for patients with small AAAs (30 to 49 mm diameter). The investigators hypothesize that exercise training will be safe and useful for patients with small AAAs.
This prospective, multi-institutional randomized clinical trial of a silver ion eluting dressing material compared to standard dry gauze for closed skin incisions after open surgical revascularizations for peripheral vascular occlusive disease. Based on the ability of the silver to lower the bacterial contamination of these vulnerable surgical skin incisions, the investigators hypothesize that immediate application of Acticoat Absorbent® as a post-operative dressing will reduce closed incisional wound complications in patients undergoing lower extremity revascularizations involving infrainguinal skin incisions compared to standard non-silver eluting dressing material.
A prospective, multi-centre, randomized controlled, First in Man study to assess the safety and performance of the coated Passeo-18 Lux Paclitaxel releasing PTA Balloon Catheter vs. an uncoated balloon catheter in patients with stenosis and occlusion of the femoropopliteal arteries.
The purpose of the Universal Registry is to assess the proportion and reasons for which subjects with angiographically significant ULMCA disease requiring revascularization during the time course of this study are not randomized; to compare the baseline characteristics of subjects; and to assess the variability in randomization eligibility and treatment patterns.
To establish the safety and efficacy of the commercially approved XIENCE Family Stent System (inclusive of XIENCE PRIME, XIENCE V, XIENCE Xpedition and XIENCE PRO [for use outside the United States [OUS] only]) in subjects with unprotected left main coronary artery disease by comparing to coronary artery bypass graft surgery.
