ReviewFrom CURE to MATCH: ADP receptor antagonists as the treatment of choice for high-risk atherothrombotic patients.
Patients with a clinical manifestation of atherothrombosis such as a recent ischaemic cerebrovascular event are at high risk of subsequent events. Atherothrombosis often reflects disseminated disease; thus, further events may occur not only in the same arterial distribution but also in other vascular beds. To achieve adequate secondary prevention in these patients, long-term antiplatelet therapy with consistent benefit across the atherothrombosis spectrum is required. ⋯ Approximately 7,600 patients will be enroled, with treatment and follow-up for each patient lasting 18 months. The primary combined efficacy endpoint will be the first occurrence of an event in the composite of IS, MI, vascular death or rehospitalization for an acute ischaemic event during the follow-up period. MATCH will explore the potential benefit of clopidogrel in high-risk stroke/TIA patients and together with CAPRIE and CURE could provide further evidence of the long-term benefit of clopidogrel in patients with major atherothrombotic manifestations.

Comparative StudyCT patterns and long-term outcome in patients with an aneurysmal type of subarachnoid hemorrhage and repeatedly negative angiograms.
The fate of patients with subarachnoid haemorrhage, an aneurysmal pattern of haemorrhage on CT and two or more negative angiographies is unknown. We studied the long-term outcome of patients with three negative angiograms (n = 15) and compared the pattern of hemorrhage of these patients with that of patients with perimesencephalic hemorrhage (n = 73). We reviewed the CT scans of all patients and we followed up the patients with three negative angiograms. ⋯ Three patients subsequently had serious vascular events; one patient (with an extended perimesencephalic pattern) died suddenly; two patients with a pattern of hemorrhage suggestive of an anterior circulation aneurysm were left disabled, one from two episodes of cerebral ischemia and another from a spontaneous intracerbral hemorrhage. In contrast to patients with perimesencephalic hemorrhage who have an uneventful clinical course and an excellent outcome, patients with three negative angiograms and an aneurysmal pattern of hemorrhage are still at some risk of vascular complications and poor outcome. Subdivisions according to the center of hemorrhage once the anterior cisterns are involved is not helpful in identifying patients with good or poor outcome.

Randomized Controlled Trial Multicenter Study Clinical TrialAnticoagulant (fluindione)-aspirin combination in patients with high-risk atrial fibrillation. A randomized trial (Fluindione, Fibrillation Auriculaire, Aspirin et Contraste Spontané; FFAACS).
A combination of low-dose aspirin with anticoagulants may provide better protection against thromboembolic events compared to anticoagulants alone in high-risk patients with atrial fibrillation. ⋯ The combination of aspirin with anticoagulant is associated with increased bleeding in elderly atrial fibrillation patients. The effect on thromboembolism and the overall balance of benefit to risk could not be accurately assessed in this study due to the limited number of ischemic events.

Case ReportsNeurometabolic changes during treatment with moderate hypothermia in a patient suffering from severe middle cerebral artery infarction.
Microdialysis is a means of measuring neurochemical changes in the extracellular space and has been applied in acute brain trauma, subarachnoid hemorrhage and stroke patients. In this study, we monitored neurochemical changes in the extracellular space using microdialysis in a patient with left-sided hemispheric infarction treated with moderate hypothermia (33 degrees C). ⋯ Concentrations of these substances in the noninfarcted hemisphere remained at normal levels. Microdialysis monitoring of therapeutic hypothermia in severe hemispheric infarction might be a useful additional monitoring tool to assess the status of the brain and to predict further deterioration.
