Filter by:The objectives of the PMS are to observe the frequency, type, and degree of device deficiency to assure the safety of the new medical device (XIENCE PRIME) as well as to collect information on evaluation of the efficacy and safety for reevaluation.
The association between obesity and cardiovascular disease (CVD) has mostly been studied using broad endpoints or have focused on cause-specific mortality. The investigators aim to compare the effect of body mass index (BMI) on different types of initial presentation of CVD.
We hypothesize that Coronary Artery Disease (CAD) severity assessed by SYNTAX score is an independent predictor of recurrent or persistent angina following coronary revascularization. The SYNTAX score is a score that suggests the severity of coronary artery disease detected by coronary angiography. Coronary revascularization is a procedure that occurs in two ways, a percutaneous coronary intervention (PCI) and a coronary artery bypass graft (CABG) and is done when there is narrowing and blockage or hardening of the arteries (atherosclerosis) surrounding the heart. Narrowing and blockages reduce blood flow to parts of the heart causing chest pain (known as angina) and sometimes myocardial infarction.
The purpose of this study is to evaluate the effect of febuxostat, once daily (QD), compared to placebo as an add on to stable anti-anginal therapy, on the total exercise time of participants with Chronic Stable Angina.
In hemodialysed patients, coronary heart disease is the leading cause of mortality and morbidity. Most of the commonly used drug for ischemia are used in this patients, but few prospective data are available. Among anti-ischemic drugs betablocker provided evidence of beneficial effects on outcome and, in dialysis patients, carvedilol was successfully used also in heart failure. Ivabradine is the latest anti-ischemic drug that provided evidence of benefit in general population, but no study is available in dialysis patients. Aim of the present study is to compare in a randomized, double-blind, parallel group trial the effects of ivabradine compared with carvedilol on event-free survival at 18 months in a hemodialysed population of patients with established coronary heart disease.
Nasal oxygen is widely used as pain relief against ischemic pain during Percutaneous Coronary Intervention (PCI). However, to our knowledge no randomised clinical trials have tested this. In contrast, oxygen causes coronary artery vasoconstriction in man. Furthermore, a recent Cochrane meta-analysis has shown no evidence of beneficial effect of oxygen for patients with acute myocardial infarction (with normal blood saturation. The investigators therefore wanted to examine if oxygen reduces ischemic pain during PCI for stable angina or NSTEMI.
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 determine whether stress echocardiography or computed tomography (CT) of the heart is better at diagnosing emergency room chest pain patients to select appropriate candidates for hospitalization and further work-up.
Standard weight-based IV heparin for normal weight patients is based on actual body weight (ABW). However, no well-defined guidelines have been established for patients considered to be obese or morbidly obese. In current practice, the calculated ABW based heparin initial bolus dose and infusion rates are quite high, and therefore often not used for obese/morbidly obese patients for fear of bleeding. Heparin is distributed in the body approximately the same as blood and does not get distributed to adipose tissue. There are some studies suggesting that lean body weight (LBW) might be a better basis for dosing heparin. LBW is a calculated weight that excludes the weight of fat. The investigators hypothesize that intravenous heparin dosing based on the Lean body weight of obese/morbidly obese patients would be safe and effective in achieving a therapeutic level of heparin in 24 hours compared to the usual practice in this patient population.
There is an increasing number of patients with a coronary anatomy that does not allow additional revascularization procedures, while the patients suffer from angina pectoris at rest or at minimal exercise levels despite optimised medical therapy. There is a lack of therapeutic options for this group of so called "no-option patients". Goal of the project is to implement the shockwave therapy for no-option coronary artery disease patients and to evaluate its potential benefit on regional myocardial perfusion, on regional myocardial function and on the potential improvement in symptoms and quality of life.
