Active clinical trials for "Infarction"

Patients with familial hypercholesterolemia (FH) at high cardiovascular risk may suffer from silent micro-infarctions (MI) before clinical coronary heart disease manifestations because of the lifetime exposure to elevated serum LDL-cholesterol levels. The study aims to demonstrate the higher prevalence of silent myocardial infarction in a population of asymptomatic patients with familial hypercholesterolemia at high cardiovascular risk in comparison to control patients using Cardiac Magnetic Resonance sequences of delayed gadolinium enhancement.

Association between serum magnesium and clinical outcome in patients with acute MI (AMI) with 1 year follow-up in 300 patients in regions supplied by desalinated drinking water (DSW) (Sheba MC) and 150 patients in regions with non-desalinated drinking water (DW) (Nahariya MC).

Aims assessment of renal artery stenosis incidence in consecutive AMI patients included in the Romanian National Programme of Primary Percutaneous Revascularisation; generating a cardio-renal-metabolic profile in patients with renal atherosclerotic disease; creating a local registry (based on European CARDS percutaneous interventional registries) which also includes renal, metabolic and vascular data; reporting long-term follow-up data on major cardiac adverse events (MACE) in the study group.

The pressure exerted by the ablation catheter on the tissue has been shown to play an important role on determining the size and the potential efficacy of the ablation lesions. A direct information on the force exerted by the catheter tip obtained from the SmartTouch technology might improve the assessment of the scar areas during electroanatomical mapping in patients with ventricular tachycardia (VT) due to ischemic disease or cardiomyopathy. The objectives of the study are to compare the areas of scar (defined as a low-voltage threshold) obtained from the conventional voltage map with those obtained after the contact map information is available to the operator and to determine if the availability of the contact information allows an improvement of the electroanatomic map by correcting the points taken in no-contact areas. Twenty to 30 consecutive patients with ventricular arrhythmias due to ischemic heart disease or dilated cardiomyopathy undergoing VT ablation will be included in a prospective, one-center, non-randomized study. A voltage map of the left ventricle will be obtained using the CARTO-3 navigation system and the scar areas as well as the areas of potential interest for ablation will be delineated in the standard way and saved as the control map. The force information will be recorded by the system but will not be available to the operator until the control map is saved. Following this step the contact map will be available to the operator to be compared with the control map and further mapping and point acquisition will be allowed to correct the areas previously acquired with poor or no contact. The final map after corrections have been made will be saved as the corrected map. The ablation procedure will then be performed as usual. Both maps will be compared in a deferred way to know how are classified the areas without contact when no pressure information is available, and how many non-contact points are falsely assumed to be low-voltage or dense scar points. These comparisons will give information on how much the standard electroanatomic map can be improved when the force information is added.

The role of lipids as risk factors for cardiovascular events is well-documented, although events studied have largely been broad classes without specific detail. This study will examine a more refined set of endpoints.

Cerebral desaturations occur frequently in patients undergoing non-cardiac surgery. The definition of what constitutes a cerebral desaturation, the incidence of the phenomenon, the association between desaturations and perioperative outcome, and the mechanistic explanations of cerebral desaturations remain unexamined. This study seeks to identify the true incidence and magnitude of cerebral desaturations in high-risk non-cardiac surgical patients and the association between desaturations and perioperative outcome. The investigators will attempt to determine the following (1) The proper definition, incidence and severity of decreased cerebral saturation (rSO2) in high-risk non-cardiac surgical patients (2) the mechanisms surrounding decreases in rSO2 by correlating it with alterations in physiologic parameters (such as blood pressure, cardiac output, hemoglobin concentration, and carbon dioxide levels) and (3) to correlate the incidence and severity of decreased rSO2 with relevant perioperative. The investigators will also analyze a panel of inflammatory biomarkers to determine if these biomarkers have the ability to predict postoperative complications. The investigators will study 200 high-risk patients undergoing high-risk non-cardiac surgery. The investigators will determine the incidence and severity of decreases in rSO2, the associated factors with the occurrence of decreased rSO2, and the relationship between decreases in rSO2 and adverse perioperative outcome with a composite of well defined perioperative complications such as death, myocardial infarction, cerebrovascular accident, acute kidney injury, delirium, postoperative infections, and the need for mechanical ventilation.

Acute Myocardial Infarction (MI) is still the leading cause of death in the western world. Early warning (chest pain) signs of an acute MI are often misinterpreted and disregarded. In average it takes between 2-3 hours from the beginning of the chest pain. The damage to the heart in these 2 hours is critical and often irreversible. Thus an early warning test or device is highly warranted. Corsens has developed a noninvasive device using several sensors applied to the chest and a detection system able to recognize the ischemic origin of chest pain. This clinical study is intended for evaluating the safety and efficacy of the Corsens technology while use for myocardial infarction detection

This study investigates whether an individualized exercise program, including a personal trainer, can improve cardiovascular status quantified with ultrasound to assess coronary flow reserve and other non-invasive techniques. The subjects in the study will be divided into two groups; one group will have a personalized exercise- and nutrition program and the other group will have acess to a gym membership, but no personal trainer.

The purpose of this study is to analyze the association between aspirin efficacy and general platelet reactivity in relation to microembolic signals (MES) during carotid endarterectomy (CEA).
