Filter by:Patients with partially blocked blood vessel(s) in their heart may need a medical procedure called "Percutaneous Coronary Intervention (PCI)" to open the narrowed blood vessel(s). The purpose of this study is to simultaneously address four potential advances in ST-Elevation Myocardial Infarction (STEMI) care for patients at least 65 years old. The investigators are looking to see if these advances can improve the outcome for these patients. 1. Opening the arteries with a Medtronic stent 2. Radial access (from wrist) success with a Medtronic stent 3. Checking the percent of blockage in the diseased artery/arteries using Volcano guide wires. 4. Reduced bleeding and vascular complications with radial arterial access for primary PCI in STEMI.
The primary objective of Part 1 of the study is to determine if BIIB093 improves functional outcome at Day 90 as measured by the modified Rankin Scale (mRS) when compared with placebo in participants with Large Hemispheric Infarction (LHI). The secondary objectives of Part 1 of the study are to determine if BIIB093 improves overall survival at Day 90 when compared with placebo, if BIIB093 improves functional outcome at Day 90 on the mRS dichotomized 0-4 vs. 5-6 when compared with placebo, if BIIB093 reduces midline shift at 72 hours (or at time of decompressive craniectomy [DC] or comfort measures only [CMO], if earlier) when compared with placebo, and to evaluate the safety and tolerability of BIIB093 in participants with LHI. The objectives of Part 2 of the study are to evaluate long-term disability following LHI, to evaluate long-term outcome measures of clinical function, quality of life, and healthcare utilization, and to assess the safety of BIIB093 in subjects with LHI during the follow-up period.
Non cardiac chest pain (NCCP) is defined as recurring, angina-like, retrosternal chest pain of non cardiac origin. Annual prevalence of NCCP in the general population of the western world ranges from 25-35%. Of those patients presenting to an emergency room with chest pain, a cardiac etiology is ultimately found in only 11-39%. Several conditions are associated with NCCP, with gastroesophageal reflux disease (GERD) being the most prevalent, constituting up to 60% of cases. However, NCCP is considered a disorder of heterogenous nature and several other conditions, apart of GERD, such as esophageal dysmotility and esophageal hypersensitivity have been implicated. Treatment of NCCP remains a real challenge due to the diverse underlying mechanisms responsible for patients' symptoms. Given the fact that GERD is by far the most common etiology, proton pump inhibitor (PPI) therapy has been tried extensively; however, after 6 weeks of treatment complete resolution of symptoms occurs in only 30% of patients, the optimal duration of PPI administration is not known, while the best maintenance dose has never been determined. Although the administration of selective serotonin reuptake inhibitors (SSRIs) could theoretically benefit those patients with esophageal hypersensitivity, the trials that have been published so far have included small number of patients and reported conflicting results, while the co-administration of PPIs with SSRIs has not been evaluated so far. Furthermore, data on treatment of patients with functional chest pain are lacking.
Increase in CK-MB after percutaneous coronary angioplasty more than 100% of baseline can represents a problem to the patients resulting in increase of morbidity and mortality. Patients submitted of coronary angioplasty procedures can release in varying degrees of creatine kinase, MB isoform (CK - MB), on the order of 30% of all angioplasty. Possibly patients who will receive sevoflurane experience a higher level of cardiac cell protection with lower incidence in the release of CK - MB values in excess of 100% baseline.
Malignant middle cerebral artery infarction(MMCI) has a high rate of disability and mortality. At present, there is no effective treatment except for craniotomy decompression, but the controversy of the craniotomy decompression still exists. The project is a prospective, randomized, single center, open label, clinical controlled trail. The eligible patients for enrollment are as follows: (1) malignant cerebral artery infarction within 48h onset; (2) craniotomy decompression can not be performed due to the contraindications, or refused by the patient or relatives. The patients are randomly assigned into 2 groups: (1)Medical therapy group: receiving osmotic therapy with mannitol and glycerol fructose，anti-platelet treatment, statins, and other symptomatic treatments such as controlling blood pressure, blood sugar, and infection, tracheal intubation or incision, etc; (2) Stereotactic infarct tissue aspiration (SITA) group: on the basis of medical treatment, receiving minimally invasive aspiration of infarct tissue 24-48 hours after stroke attacked. This study is aimed at comparing the efficacy and safety of of SITA in patients with MMCI.
This is a study to evaluate the hypothesis that FDA cleared thrombectomy devices plus medical management leads to superior clinical outcomes in acute ischemic stroke patients at 90 days when compared to medical management alone in appropriately selected subjects with the Target mismatch profile and an MCA (M1 segment) or ICA occlusion who can be randomized and have endovascular treatment initiated between 6-16 hours after last seen well.
The purpose of this study is to evaluate whether the use of bivalirudin will reduce extent of the damage done to the heart muscle in participants who suffered a heart attack, compared to the comparator treatment (heparin).
Myocardial infarction (MI) frequently recurs after non-ST elevation MI (NSTEMI) that may be related to insufficient vulnerable plaque identification using invasive coronary angiography. Furthermore, the natural behaviour of vulnerable plaques in NSTEMI over time and their relation with biomarkers need further exploration. More accurate identification and assessing long-term behaviour of vulnerable plaques may improve therapeutic strategies and clinical outcome. The investigators hypothesize that fully integrated 18Fluoride Sodium-Fluoride (18F-NaF) Positron Emission Tomography/Cardiac Magnetic Resonance imaging (PET/CMR) increases the ability to detect vulnerable plaques as compared to coronary angiography. This prospective study in 33 consecutive patients with NSTEMI aims to: 1. Compare coronary vulnerable plaque detection between 18F-NaF PET/CMR and invasive coronary angiography, 2. Investigate the correlation of coronary vulnerable plaques using 18F-NaF PET with myocardial infarction using CMR, both at baseline and during follow-up, 3. Examine systemic arterial 18F-NaF-uptake using PET/CMR and their relation with systemic events (cerebrovascular accidents, transient ischemic attacks, or peripheral arterial disease), and 4. Examine the relation between vulnerable plaques and plasma biomarkers.
Aim of the study is the determination of the ideal timepoint for the treatment of patients with acute Non-ST-segment Elevation Myocardial Infarction (NSTEMI) and an acute or chronic kidney disease (CKD) with a GRACE score < 140. It should be determine if a prompt coronary angiography or the protection of the kidneys from the used contrast agent is more important for the outcome of the patients. Additionally it will be investigated if the ischemic precondition can help to prevent heart damages.
The BERLIN VT study is designed to evaluate the impact of prophylactic ventricular tachycardia (VT) ablation on all-cause mortality and unplanned hospital admission for congestive heart failure or symptomatic ventricular tachycardia/ventricular fibrillation (VF) when compared to VT ablation after the third appropriate implantable cardioverter-defibrillator (ICD) shock.
