Filter by:Restoring the patency of the coronary vessels and providing the ischemic myocardium with reperfused blood can cause additional tissue damage. A key element of ischemia and reperfusion (I/R) injury and major determinant of the evolution of damage in the affected myocardium is the inflammatory response. The main objective of the study is to evaluate the efficacy of colchicine in reducing I/R injury by effectively modulating the inflammatory response in the reperfused myocardium.
Research hypothesis: Is the treatment with renal denervation (RDN) early post ACS safe and effective and does it leads to improved cardiac function and attenuation of pathologic left ventricular remodelling? In a following study, the hypothesis will be tested in a larger ACS population with major adverse cardiovascular events (MACE) after ACS as the endpoint. Rationale for conducting this study: ACS i.e. ST-elevation myocardial infarction (STEMI) and non- ST-elevation myocardial infarction (non-STEMI) are the most important causes of morbidity and mortality in western societies. Hypertension is a major risk factor for development of ACS and heart failure but it also worsens the prognosis in patients after ACS. Our research highlights the combination therapy of PCI and RDN in an ACS patient population with simultaneous hypertension. Primary objective: The primary objective of this study is to establish safety and efficacy of combined treatment with PCI and renal denervation (RDN) in hypertensive patients with acute coronary syndromes (STEMI and non-STEMI ) having ventricular mass after 4 months as the primary variable. Endpoints: The primary end point is change in left ventricular mass (LVM) at 4 months evaluated by magnetic resonance imaging (MRI). Secondary endpoints:, blood pressure (office and 24-h ABPM), and left ventricular volumes and ejection fraction.
This study aims to assess usual walking speed (4-metre gait speed) in patients undergoing primary percutaneous coronary intervention (PCI) for acute myocardial infarction and to assess whether this can predict future cardiovascular events and death.
Despite the well-known health benefits of physical exercise in the prevention of chronic diseases, less attention has been focused on the use of physical exercise as an essential part of good treatment for chronic disease. The aims of the study are to investigate the feasibility, medical effects, cost-effectiveness, and social perspectives of the individualized exercise-based rehabilitation [2 different high-intensity training (HIT) protocols combined with usual care (UC)] after acute coronary artery disease (CAD) event. The medical aim is to study mediating mechanisms of the physiological, biochemical and molecular effects of exercise training on the clinical outcomes. The aim of the health-economic evaluation is to assess the changes in the Health-Related Quality of Life (HRQL) and health care related costs for estimating the cost-effectiveness of HIT-based exercise rehabilitation. The purpose of the sociological analysis is to find out the social processes which make possible the emergence of the desired welfare effects.
Rationale: Compared with balloon angioplasty, implantation of bare metal stents (BMS) and drug eluting stents (DES) have shown to reduce repeat target lesion revascularization in primary percutaneous coronary intervention (PPCI). However, this did not result in a reduction of mortality or recurrent myocardial infarction. Furthermore, there are concerns of the occurrence of stent thrombosis. The PAPPA-pilot study, evaluating safety and feasibility of using a drug-coated balloon (DCB) only strategy in PPCI, showed good short- and long-term clinical results, with sustained safety and efficacy at 12 months follow-up. To date little is known about the long-term effects of this treatment modality in STEMI. Besides, angiographic follow-up is of great clinical importance by giving insight on the treated infarct lesion and to assess the functional angioplasty result. Objective: This randomized controlled, non-inferiority trial is mainly designed to prospectively assess the safety and efficacy of a CE-marked paclitaxel-eluting balloon only strategy vs. third generation DES in the setting of a ST-elevation myocardial infarction (STEMI).
Previous trials have demonstrated that the use of physiological assessment of stenosis severity using fractional flow reserve (FFR) is superior to angiographic assessment in percutaneous coronary intervention (PCI) and improves clinical outcome. Despite the clinical utility, FFR is used only in 10-15% of patients today. The main reasons for the low adoption rate of FFR are the prolonged procedural time, Adenosine related discomfort and cost associated with Adenosine. Instantaneous Wave-Free ratio (iFR®) is a novel method to assess coronary lesions for functional significance. The main benefits of the method compared to FFR are that the measurement is instantaneous and does not require Adenosine infusion. Thus, the patient does not experience any discomfort from the measurement and procedural time could be shortened compared to when using FFR. This could potentially increase the adoption rate of physiologic assessment of coronary lesions. The aim of this trial is to compare the clinical outcome of patients assessed by iFR® with patients assessed by FFR. Furthermore, the trial will be conducted as a registry based randomized clinical trial (RRCT) which is a novel strategy to conduct clinical trials. The randomization will occur online in the Swedish angiography and angioplasty registry (SWEDEHEART) using a web based platform.
The purpose of this study is to determine if a device known as the TandemHeart® System (TandemHeart) can help limit heart damage and reduce serious complications after a certain type of heart attack (acute ST elevation anterior wall myocardial infarction [STEMI]) by evaluating the use of the TandemHeart system prior to a procedure called percutaneous coronary intervention (PCI)
To evaluate the safety, performance and efficacy of the bioresorbable vascular scaffold (BVS) system in patients with coronary artery disease
This is a 6-month pilot study intended to test the effect of financial incentives on improving medication adherence in AMI patients; to test the effect on adherence of removing financial incentives; and to test the effect on the enrollment rate of modifying recruitment procedures.
Patients presenting with large myocardial infarction and signs of persistent ischemia after successful percutaneous coronary intervention, have a poor prognosis with respect to outcome and development of heart failure in the future. The hypothesis of this study is that in patients in whom persistent ischemia is present, use of intra-aortic balloon pump will be beneficial and improve outcome.
