Prevention of ischemic stroke: antithrombotic therapy in cardiac embolism

Area of Science:

• Cardiology
• Neurology
• Pharmacology

Background:

• Ischemic stroke from cardiac disease constitutes ~30% of all strokes.
• Cardioembolic strokes lead to worse outcomes, higher mortality, and increased healthcare costs.
• Accurate identification of cardioembolic stroke is critical for selecting optimal preventive strategies.

Purpose of the Study:

• To review the neuro-cardiological interactions between the heart and brain.
• To emphasize current and emerging antithrombotic therapies for stroke prevention in patients with atrial fibrillation.
• To discuss antithrombotic strategies for diverse cardiac conditions.

Main Methods:

• Literature review focusing on cardioembolic stroke.
• Analysis of antithrombotic drug efficacy and safety.
• Synthesis of evidence for various cardiac conditions predisposing to stroke.

Main Results:

• Atrial fibrillation is a major cause of cardioembolic stroke, necessitating tailored antithrombotic therapy.
• Newer oral anticoagulants show promise but require careful patient selection.
• Evidence supports specific antithrombotic approaches for conditions like patent foramen ovale, valve disease, and post-myocardial infarction.

Conclusions:

• Optimizing stroke prevention in cardiac patients requires precise diagnosis and individualized antithrombotic treatment.
• Understanding heart-brain interactions informs therapeutic decisions.
• Continued research into novel anticoagulants and antiplatelet agents is essential for reducing stroke burden in cardiovascular disease.
