Initial Assessment and Management for Suspected CVA

Patient Assessment

The American Heart Association recommends using the FAST (Face, Arm, Speech, Time) assessment tool to identify patients with suspected cerebrovascular accident (CVA), which includes evaluating facial asymmetry, arm drift, speech difficulties, and time of symptom onset 1
Patients presenting with transient, fluctuating, or persistent unilateral weakness, speech disturbance, or other symptoms suggesting posterior circulation stroke should be immediately transported to an emergency department with advanced stroke care capabilities 2, 3

The American College of Cardiology recommends stratifying patients into VERY HIGH, HIGH, MODERATE, and LOWER risk categories based on symptom presentation and time of onset, with corresponding actions including immediate transport to an emergency department, comprehensive evaluation within 24 hours, and evaluation by a neurologist or stroke specialist within one month 2, 3, 4

The American Heart Association recommends activating emergency medical services (EMS) immediately for suspected stroke, minimizing on-scene time, and performing an initial assessment including blood glucose measurement, symptom onset time, and medical history 1
Patients should be transported directly to a hospital capable of providing acute stroke services, with consideration of bypass protocols to reach appropriate stroke centers 1

The American College of Radiology recommends immediate brain imaging using CT or MRI, as well as vascular imaging to identify significant carotid stenosis, and cardiac assessment including 12-lead ECG and cardiac monitoring for potential atrial fibrillation 2, 3, 5, 6
Laboratory tests should include complete blood count, electrolytes, coagulation studies, renal function, blood glucose, and troponin 5, 6

The American Heart Association recommends prompt evaluation for patients presenting with amaurosis fugax (transient monocular blindness) and posterior circulation symptoms, which may present with less obvious signs such as dizziness, ataxia, or visual disturbances 7
