Symptome, Risikofaktoren und Ätiologie von transitorisch ischämischer Attacke und Schlaganfall

[Management of acute ischemic stroke]

The management of acute ischemic stroke aims to verify the clinical diagnosis, to start general supportive care and to enable decision-making about specific forms of therapy.The risk-benefit ratio is time-dependent for many therapeutic options; therefore time delays are a disadvantage within the rescue chain. The trained and multidisciplinary team of the stroke unit forms the backbone of acute management. In addition, technical infrastructure influences therapeutic options and cerebral imaging is the cornerstone.The following four therapies are evidence-based: treatment on a stroke unit, thrombolysis, early administration of acetylsalicylic acid (ASS) and hemicraniectomy in patients younger than 60 years with a so-called malignant infarction.This article describes the necessary diagnostic steps and the general and specific therapeutic options that comprise acute management within the first 48 h.

Vascular risk factor awareness before and pharmacological treatment before and after stroke and TIA

BACKGROUND AND PURPOSE

Educating the public to screen for vascular risk factors and have them treated is a major public health issue. We assessed the vascular risk factor awareness and frequency of treatment in a cohort of patients with cerebral ischaemia.

METHODS

Data on awareness and pharmacological treatment of vascular risk factors before hospital admission of patients with confirmed ischaemic stroke/transient ischaemic attack (TIA) were analyzed. A follow-up questionnaire assessed the frequency of treatment 1 year after discharge and assessed non-adherence to antithrombotic medication.

RESULTS

At time of stroke/TIA, individual awareness regarding existing hypertension, diabetes, hyperlipidemia and atrial fibrillation (AF) was 83%, 87%, 73% and 69% respectively (n = 558). Pharmacological treatment for hypertension, diabetes, hyperlipidemia and AF was being administered in 80%, 77%, 37% and 62% of patients aware of their conditions. The follow-up was completed by 383 patients (80% recall rate): of the patients with hypertension, diabetes, hyperlipidemia and AF, 89%, 78%, 45% and 86% were receiving risk factor targeted medication. This represents a significant increase concerning AF and hyperlipidemia. Non-adherence to recommended antithrombotics (15%) was higher in patients who had had a TIA.

CONCLUSIONS

All risk factors leave room for improvement in screening and treatment efforts. Adherence to treatment is higher for hypertension and diabetes than for hyperlipidemia. Education efforts should bear in mind less well recognized risk factors.
