Clinical Practice Guidelines on the Management of Acute Ischemic Stroke and Intracerebral Hemorrhage in the Philippines 2024
Note: The provided evidence does not contain the specific 2024 Philippine Clinical Practice Guidelines requested. However, based on the most recent international guidelines and Philippine stroke care context, here is a synthesis of key management recommendations:
Acute Ischemic Stroke Management
Thrombolytic Therapy
Intravenous thrombolysis remains the cornerstone of acute ischemic stroke treatment when administered within the appropriate time window. Blood pressure must be maintained below 185/110 mmHg before treatment and below 180/105 mmHg for 24 hours post-thrombolysis 1.
Key parameters:
- Do not initiate anticoagulant or antiplatelet therapy within 24 hours of IV rtPA 1
- Target modest BP reductions of approximately 15% within 24 hours for patients not receiving reperfusion therapy when SBP ≥220 mmHg or DBP ≥120 mmHg 2
Antiplatelet Therapy
Administer aspirin 325 mg orally within 24-48 hours after stroke onset for patients not receiving thrombolysis 1. This provides modest but statistically significant reduction in mortality and unfavorable outcomes, primarily through prevention of early recurrent stroke 1.
Critical restrictions:
- Aspirin is not a substitute for IV rtPA 1
- Do not give aspirin or other antiplatelet agents within 24 hours of thrombolysis 1
Anticoagulation
Urgent anticoagulation is not recommended for preventing early recurrent stroke, halting neurological worsening, or improving acute outcomes 1. This applies even to patients with cardioembolic sources, as early anticoagulation increases bleeding risk without reducing early recurrent stroke 1.
Intracerebral Hemorrhage Management
Blood Pressure Control
Rapidly reduce systolic blood pressure to approximately 140 mmHg in acute ICH, while avoiding overshoot, large variability, and excessive early declines 3, 2. This aggressive early BP reduction is critical as hematoma expansion commonly occurs within the first hours and strongly predicts mortality 4.
Specific targets:
- Acute phase: SBP target ~140 mmHg 2
- Long-term: BP <130/80 mmHg 2
- Use calcium channel blockers for acute parenteral therapy 2
Time-Sensitive Interventions
Implement bundled care pathways focused on limiting hematoma expansion within the first hours 4, 5. Priority interventions include:
- Rapid neuroimaging
- Controlled BP reduction
- Timely anticoagulation reversal
- Seizure management when indicated
- Prompt neurosurgical consultation 4
Philippine Context Considerations
The Philippines faces significant stroke care gaps that impact guideline implementation 6:
Current Challenges
- Thrombolysis rate improved to 11% in 2021 (up from 1.4% in 2014-2016) 6
- Government hospitals achieve 7.4% thrombolysis rate vs 4.8% in private hospitals due to government subsidy 6
- Mechanical thrombectomy remains extremely low at 0.4% due to cost 6
- Limited neurologists, CT scan machines, and stroke-trained health workers 6
Practical Adaptations
Non-neurologists can be trained to deliver acute stroke care in areas with limited specialist availability 6. Government insurance coverage (PhilHealth) requires upgrading to adequately cover reperfusion therapies 6.
Secondary Prevention
Long-term Blood Pressure Management
Target BP <130/80 mmHg for chronic management after both ischemic stroke and ICH 2. Use thiazide diuretics, ACE inhibitors, or angiotensin receptor blockers as foundational therapy 2.
Antiplatelet Therapy
Continue long-term antiplatelet therapy for ischemic stroke prevention, with specific agent selection based on stroke mechanism and patient factors 1.
Critical Pitfalls to Avoid
- Never delay thrombolysis to administer aspirin - aspirin can wait 24 hours 1
- Never give anticoagulants or antiplatelets within 24 hours of rtPA - this significantly increases hemorrhagic complications 1
- Never use urgent anticoagulation to prevent early stroke recurrence - it doesn't work and increases bleeding 1
- Never delay ICH blood pressure reduction - hematoma expansion occurs early and determines outcome 4, 5
- Avoid excessive BP lowering in acute ischemic stroke without reperfusion therapy unless severely elevated 2
