Filter by:Cerebral infarction is a major health problem. The two most common causes are atherosclerosis (30 to 35%) and cardio-embolic origin (35 to 40%). However, in 25% of cases the cause is undetermined, known as cryptogenic stroke or stroke of undetermined origin. Paroxysmal Atrial Fibrillation appears to cause a significant proportion of these cryptogenic cerebral infarctions. One of the major challenges in the management of cerebral infarctions is the prevention of recurrence. If the cause is atheromatous, treatment is based on platelet antiaggregants and the correction of cardiovascular risk factors. If the cause is atrial fibrillation, the treatment of choice is anticoagulation therapy. Cryptogenic strokes are managed with antiplatelet therapy. In past studies, the thrombi responsible for cerebral infarctions have been analyzed anatomopathologically to see if the composition of the thrombi could help identify the cause of the cerebral infarction. These studies have proved to be contradictory. The composition of the bacterial flora of cerebral infarct thrombi has not yet been studied, apart from some limited data on septic emboli. In myocardial infarction, the cause of which is almost exclusively atheromatous, bacteria of the periodontal flora have been detected in thrombi of ST-segment elevation infarctions. The causes of cerebral infarction are multiple. The hypotheses explored in this study are that there are differences in the composition of the bacterial flora of the thrombus depending on whether the cause is atheromatous or cardio-embolic and that the study of the composition of the thrombus could be used to identify the cardio-embolic cause in patients with cryptogenic cerebral infarction.
Randomized clinical study evaluating superiority in platelet inhibition after administration of Ticagrelor 180 mg loading dose as an orodispersible formulation versus traditional coated tablets in patients admitted for ST elevation myocardial infarction or very high-risk non-ST elevation myocardial infarction.
In this controlled trial, patients referred to post-myocardial infarction cardiac rehabilitation will be randomized to either interval or continuous training.
Myocardial infarction causes necrosis of myocardial cells and reduces cardiac function. Today, there are treatments such as primary angioplasty and thrombolysis that are effective in limiting cell death after acute myocardial infarction. However, the post-infarct scar often conditions a global ventricular remodeling that can evolve clinically towards heart failure and in more advanced stages the only therapy that completely restores cardiac function is heart transplantation. Mesenchymal stem cells are multipotent cells found from embryonic mesoderm and found in all tissues. In the field of cardiac regeneration, studies have shown a certain degree of benefit when treated with MSCs from different origins. Our approach is based on a decellularized matrix that carries the cells directly over myocardial infarction.
The study intends to provide important data on whether the noval method using quantitative flow ratio could predict microvascular dysfunction.
In this parallel randomized controlled trial (n = 33/group), the control group received routine care, while the intervention group received a telephone follow-up intervention, which consisted of a pre-discharge education program and three telephone follow-up sessions based on the Roy Adaptation Model.
This is a multicentre observational study planned to gather follow up data for a period of 1 year in order to understand the treatments and outcomes of ST-segment elevation myocardial infarction(STEMI) and improve medical care quality in Fujian province for China. Consecutive patients who were admitted and diagnosed with STEMI between January 2014 December 2018 were conducted at five regional representative hospitals in Fujian province, which included the Fujian Provincial Hospital,Longyan First Hospital, the affiliated hospital of putian university,the Second Affiliated Hospital of Fujian Medical University and Mindong Hospital of Ningde City.
Unplanned readmissions after hospitalization for acute myocardial infarction (AMI) are among the leading causes of preventable morbidity, mortality, and healthcare costs. Digital health interventions (DHI) could be an effective tool in promoting self-management, adherence to guideline directed therapy, and cardiovascular risk reduction. A DHI developed at Johns Hopkins-the Corrie Health Digital Platform-includes the first cardiology Apple CareKit smartphone application, paired with an Apple Watch and iHealth Bluetooth-enabled blood pressure monitor. Corrie targets: (1) self-management of cardiac medications, (2) self-tracking of vital signs, (3) education about cardiovascular disease through articles and animated videos, and (4) care coordination that includes cardiac rehabilitation and outpatient follow-up appointments. In this prospective study, STEMI or type 1 NSTEMI patients are being enrolled to use the Corrie Health Digital Platform beginning early during participants' hospital stay. Enrollment sites include Johns Hopkins Hospital, Johns Hopkins Bayview Medical Center, Massachusetts General Hospital, and Reading Hospital. The primary objective is to compare time to first readmission within 30 days post-discharge among patients with the Corrie Health Digital Platform to patients in the historical standard of care comparison group.
The aim of the study was to use data from the Myocardial Ischaemia National Audit Project (MINAP) to investigate whether temporal improvements in survival were associated with changes in patients' baseline clinical risk or use of guideline-indicated treatments for the management of STEMI, and to determine the extent to which associations explained the temporal improvements in survival.
Cardiac rehabilitation reduces morbidity and mortality after myocardial infarction (MI) and improve the sympathovagal balance. The autonomic nervous system (ANS) can be explored by the variation of heart rate (HRV). The HRV is a fatigue marker and guides the athletes training programs. A smartphone app can measure the HRV via a heart rate monitor. The main study objective is to compare the effect on the functional capacities of a re-training adapted to the HRV compared to a standard program in the post-MI The secondary objective is to compare the patients' quality of life according to the rehabilitation program and to validate the HRV smartphone app. This is a prospective, multicenter study. Post-MI patients treated with angioplasty with a LVEF> 40% are randomized into 2 groups: HRV (re-training adapted to HRV daily: 10W decrease or increase in workload according to the HRV) or control (continuous training in SV1). Patients underwent a cardiopulmonary test, a walking test (TM6) and a SF36 questionaries' at the entrance and exit. The taking of HRV was done every morning in a standardized way via the smartphone app during the 20 re-training sessions.
