Clinical Question


In patients with recent stroke or TIA and without known coronary heart disease, does atorvastatin reduce the risk of subsequent strokes or cardiovascular events?

Bottom Line


In patients with recent stroke or TIA and without known coronary heart disease, daily treatment with 80 mg of atorvastatin reduced the overall incidence of strokes and major cardiovascular events, despite a small increase in the incidence of hemorrhagic stroke.

Major Points


Although statins are known to reduce the incidence of stroke in patients at increased risk of cardiovascular disease, their efficacy in preventing stroke after a recent stroke or TIA was not well established. SPARCL was therefore designed to investigate whether high-dose atorvastatin therapy could reduce the risk of subsequent stroke in this patient population.

Guidelines


Since the publication of SPARCL, subsequent guidelines have recommended statin therapy for secondary prevention in patients with ischemic stroke or TIA who have evidence of atherosclerosis.

Design


Randomized, double-blind, placebo-controlled trial.

Population


Inclusion Criteria: - Age >18 years - Stroke or TIA within one to six months of study entry - LDL cholesterol levels 100-190 mg/dL - No known coronary heart disease

Exclusion Criteria: - Atrial fibrillation, other cardiac sources of embolism, and subarachnoid hemorrhage

Baseline Characteristics: - Mean age: ~63 years - 60% male - Median LDL cholesterol: ~133 mg/dL - Previous stroke: 66%

Interventions


- Atorvastatin 80 mg per day versus placebo

Outcomes


Primary Outcome: - First nonfatal or fatal stroke

Outcomes


- Stroke or TIA - Major coronary event - Major cardiovascular event - Acute coronary event - Any coronary event - Revascularization procedure - Any cardiovascular event

Criticisms


- Increased risk of hemorrhagic stroke

Funding


Supported by Pfizer.
