Introduction

Every minute a large-vessel occlusion goes untreated, approximately 1.9 million neurons are lost. Acute ischemic stroke (AIS) accounts for roughly 85% of all strokes and remains a leading global cause of death and long-term disability. Rapid reperfusion with intravenous thrombolysis within 4.5 hours and endovascular thrombectomy in selected patients up to 24 hours can dramatically reverse this damage and improve functional outcomes.

In Pakistan, stroke incidence is rising, often striking at younger ages, with delayed presentation, limited 24/7 advanced imaging outside major cities, and scarce endovascular centers compounding the challenge. Hypertension and diabetes epidemics fuel the burden, while organized stroke pathways and secondary prevention remain priorities. This evidence-based acute stroke management protocol outlines time-critical steps aligned with AHA/ASA, AAN, and NICE principles to save brain and reduce disability. Early recognition and transfer to equipped centers like Faraz Hospital are essential.

What is it?

Acute ischemic stroke occurs when a blood clot or embolus suddenly occludes a cerebral artery, depriving brain tissue of oxygen and glucose. The ischemic core dies rapidly while the surrounding penumbra remains potentially salvageable if blood flow is restored quickly. Large-vessel occlusions (LVO) of the internal carotid artery (ICA) or middle cerebral artery (M1/M2) produce the most severe deficits and benefit most from advanced reperfusion.

AIS differs from hemorrhagic stroke; distinguishing the two immediately via imaging is mandatory before any clot-busting therapy. Time is brain: door-to-needle targets under 60 minutes and door-to-puncture under 90–120 minutes define high-performing systems. Systems of care emphasizing EMS pre-notification, telestroke, and organized stroke units (as stressed by AAN and NICE) improve rates of timely treatment. In resource-variable settings such as Pakistan, hub-and-spoke models and public awareness campaigns help bridge gaps until full endovascular capability expands. Understanding AIS pathophysiology underpins every step of the acute stroke management protocol—from EMS activation through secondary prevention.

Causes

The most common mechanisms of AIS are large-artery atherosclerosis, cardioembolism (especially atrial fibrillation), small-vessel lacunar disease, and other determined or undetermined etiologies (TOAST classification). Risk factors prevalent in Pakistan include uncontrolled hypertension, diabetes mellitus, smoking, dyslipidemia, obesity, and increasingly younger patients with premature atherosclerosis.

Cardioembolic sources rise with aging populations and rheumatic heart disease residues. Hypercoagulable states, arterial dissection, and vasculitis occur less frequently. Secondary prevention must target the specific mechanism once the acute phase stabilizes—statins, antiplatelets or anticoagulation, blood-pressure control, and lifestyle measures. Addressing these root causes after the hyperacute window is integral to any complete acute stroke management protocol and reduces recurrence risk substantially.

Symptoms – bold red flags

Recognize these bold red flags immediately—use the BE FAST mnemonic and call emergency services without delay:

– Balance sudden loss or severe dizziness
– Eyes sudden vision loss or double vision in one or both eyes
– Face facial droop or asymmetry
– Arm (or leg) sudden weakness or numbness, usually unilateral
– Speech slurred speech, inability to speak, or incomprehensible words
– Terrible headache or sudden confusion (less specific but concerning)
– Time — note exact onset; “last known well” time is critical for eligibility

Additional red flags include sudden severe ataxia, gaze deviation, neglect, or rapidly declining consciousness. In LVO, NIHSS scores are typically ≥6. Any sudden focal neurological deficit warrants immediate transport to a stroke-ready facility. Do not wait for symptoms to improve; public education on these signs shortens onset-to-door times, the single greatest barrier in many Pakistani communities.

Diagnosis at Faraz Hospital

At Faraz Hospital, Bahawalpur, suspected AIS patients undergo immediate clinical assessment with NIHSS scoring and non-contrast CT to exclude hemorrhage. Our BodyTom portable CT enables rapid, high-quality imaging even in constrained spaces, facilitating door-to-imaging times that support thrombolysis decisions.

Where indicated, CTA or CT perfusion evaluates vessel occlusion and salvageable penumbra, guiding extended-window thrombectomy eligibility (DAWN/DEFUSE-3 criteria). MRI is used selectively. Dysphagia screening, ECG, labs (glucose, coagulation, troponin), and continuous monitoring complete the work-up. This streamlined pathway mirrors AHA/ASA and NICE recommendations for organized stroke care and positions eligible patients for timely reperfusion while identifying those needing neurosurgical input for malignant edema or other complications.

Treatment

The cornerstone of the acute stroke management protocol is rapid reperfusion. Intravenous alteplase 0.9 mg/kg (maximum 90 mg; 10% bolus, remainder over 60 minutes) is given within 4.5 hours of last known well if no contraindications exist, after blood pressure is controlled below 185/110 mmHg. The landmark NINDS rt-PA trial established its benefit.

For ICA or proximal M1 (and selected M2) occlusions with NIHSS ≥6 and ASPECTS ≥6, endovascular thrombectomy is indicated within 6 hours; selected patients with clinical-core mismatch may be treated up to 24 hours per DAWN trial criteria. AHA/ASA 2018 guidelines endorse these windows. Mechanical thrombectomy requires endovascular readiness; neurosurgical teams manage complications or decompressive craniectomy when needed.

At Faraz Hospital we utilize BodyTom CT for immediate imaging guidance and the Zeiss operating microscope for any microsurgical interventions required in complex or hemorrhagic-conversion cases. Adjunctive care includes aspirin 24–48 h after thrombolysis (or sooner if no lytic), DVT prophylaxis, glycemic and temperature control, and early swallow assessment. Secondary prevention—high-intensity statin, antiplatelet or anticoagulant tailored to etiology, and risk-factor modification—begins in hospital. This protocol, executed in an organized unit, measurably improves outcomes.

Recovery

Recovery begins in the hyperacute phase with prevention of complications and early mobilization once stable. Multidisciplinary rehabilitation—physiotherapy, occupational therapy, speech and language therapy—maximizes neuroplasticity in the first weeks to months. Many patients achieve meaningful independence; outcomes correlate strongly with time-to-reperfusion and initial stroke severity.

In Pakistan, structured rehab access varies; family education and community follow-up are vital. Blood-pressure control, medication adherence, smoking cessation, and diabetes management form lifelong secondary prevention. Regular outpatient review detects late complications such as spasticity, depression, or seizures. With modern reperfusion and dedicated aftercare, substantial recovery is realistic for a growing proportion of AIS survivors.

FAQ

1. What is the time window for tPA in acute ischemic stroke?
Intravenous alteplase is approved up to 4.5 hours from last known well in eligible patients after hemorrhage is excluded.

2. Who qualifies for endovascular thrombectomy?
Patients with LVO (ICA/M1, selected M2), significant deficits (usually NIHSS ≥6), favorable ASPECTS, within 6 hours, or up to 24 hours with perfusion mismatch (DAWN criteria).

3. Why is blood pressure controlled before thrombolysis?
BP must be <185/110 mmHg to reduce hemorrhagic transformation risk; careful lowering continues afterward as needed.

4. How does Faraz Hospital diagnose AIS quickly?
Immediate NIHSS, BodyTom non-contrast CT (± CTA/CTP), labs, and ECG enable rapid treatment decisions aligned with international protocols.

5. What secondary prevention is started after AIS?
Antiplatelet or anticoagulant therapy (per etiology), high-intensity statin, BP and glucose control, lifestyle changes, and early rehabilitation.
