Insights
Thrombolysis is an effective treatment for acute ischemic stroke, improving outcomes when guided by advanced imaging beyond traditional time windows. This approach personalizes stroke care, aiming to reduce disability and the socioeconomic burden of stroke.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Medical Imaging
Background:
- Stroke is a leading cause of death and disability globally.
- Thrombolysis is the primary treatment for acute ischemic stroke within 3 hours.
- Current treatment often relies on rigid time windows, potentially excluding eligible patients.
Purpose of the Study:
- To provide an overview of thrombolytic therapy in acute stroke.
- To present a diagnostic approach for individualized stroke management.
- To develop a treatment algorithm based on pathophysiological reasoning and advanced imaging.
Main Methods:
- Review of current thrombolytic therapy status in stroke.
- Development of a treatment algorithm using multiparametric stroke magnetic resonance imaging (MRI).
- Integration of pathophysiological information for patient selection.
Main Results:
- Thrombolysis is effective intravenously (3h) and intra-arterially (3-6h).
- Evidence supports extended thrombolysis beyond 3 hours with advanced MRI selection criteria.
- Thrombolytic therapy remains underutilized despite proven efficacy.
Conclusions:
- Personalized stroke management using advanced MRI can optimize thrombolysis.
- Expanding treatment eligibility criteria may increase thrombolysis use.
- Increased adoption of effective thrombolysis can reduce the socioeconomic impact of stroke.
Purpose Of Review:
Stroke is the third leading cause of death after myocardial infarction and cancer, and is the leading cause of permanent disability and disability-adjusted loss of independent life-years in western countries. Thrombolysis is the treatment of choice for acute stroke within 3 h after the onset of symptoms. We present an overview of a diagnostic approach to acute stroke management that allows the individualization of patient management based on pathophysiological reasoning and not rigid time windows established by randomized controlled trials.
Recent Findings:
This review concentrates in the first part on giving the reader an integrated knowledge of the current status of thrombolytic therapy in stroke, and in the second part develops a treatment algorithm based on pathophysiological information rendered by a multiparametric stroke magnetic resonance imaging protocol.
Summary:
Thrombolysis is an effective therapy for ischemic stroke, whether performed intravenously within 3 h or intra-arterially within 3-6 h. Meta-analyses have provided evidence of an effect of intravenous thrombolysis beyond the 3 h time window, especially when improved selection criteria such as modern magnetic resonance imaging protocols are applied. Sadly, thrombolysis is still underused. Positive results from studies currently underway may encourage more centers to offer this therapy to an increasing number of stroke patients, and thereby reduce the considerable socioeconomic burden of stroke.
