Insights
Pre-interventional statin therapy significantly reduces the risk of stroke, myocardial infarction, and death in patients undergoing carotid artery stenting. This finding supports statins as a standard pre-treatment for carotid stenting procedures.
Area of Science:
- Cardiology
- Neurology
- Vascular Surgery
Background:
- Statins are proven to reduce cardiovascular and cerebrovascular events.
- Limited data exist on pre-interventional statin use in carotid artery stenting compared to endarterectomy.
- Investigating statin's role in peri-interventional risk reduction for carotid stenting is crucial.
Purpose of the Study:
- To determine if pre-interventional statin therapy is associated with reduced peri-interventional risk.
- To analyze the impact of statins on stroke, myocardial infarction, and mortality in carotid stenosis patients undergoing stenting.
Main Methods:
- Retrospective analysis of 344 patients with internal carotid artery stenosis treated with stent-angioplasty (2002-2012).
- Data collected prospectively, including risk factors, medications, and indications for therapy.
- Univariate and multivariate analyses performed to assess independent effects of statin medication.
Main Results:
- 60.2% of patients received pre-interventional statin medication.
- Multivariate analysis showed statins significantly reduced the risk of peri-interventional ischemic stroke, myocardial infarction, or death (OR 0.31, p = .006).
- Statins also demonstrated a protective effect on secondary endpoints, including ischemic stroke, intracranial bleeding, or death (OR 0.39, p = .014).
Conclusions:
- Pre-interventional statin medication offers a protective effect against peri-interventional stroke, myocardial infarction, or death in carotid stenting.
- Statins should be considered a standard pre-interventional therapy for patients undergoing carotid stenting.
- This supports the broader use of statins in cardiovascular prevention strategies.
Background:
In primary and secondary prevention, statins significantly reduce cardiovascular and cerebrovascular events. Pre-interventional statin medication shows a benefit in carotid artery stenosis patients treated with endarterectomy; however, there are few data available for patients treated with stent-angioplasty. The aim of this study was to investigate whether pre-interventional statin therapy is associated with decreased peri-interventional risk of stroke, myocardial infarction, and mortality in patients undergoing stent-angioplasty for internal carotid stenosis.
Methods:
Data for 344 consecutively documented patients with internal carotid artery stenosis treated with stent-angioplasty in the years 2002-2012 at the same stroke center were collected in a prospectively defined database. Risk factors, medication, and indication for therapy were documented. Univariate and multivariate analysis was performed to investigate independent reduction of peri-interventional stroke, myocardial infarction, or death by statin medication prior to stent-angioplasty.
Results:
The median age was 70 years (p25: 63, p75: 76), 75.5% of patients were male, and the median stenosis was 85% according to ECST criteria (p25: 80%, p75: 90%). 20.1% of patients had asymptomatic stenoses, and 60.2% had statin medication before stenting. As per multivariate analysis, pre-interventional statin medication was a predictor for significant peri-interventional risk reduction regarding primary endpoint ischemic stroke, myocardial infarction (MI), or death (odds ratio (OR) 0.31, p = .006). Statins also had a significant protective effect in secondary endpoint ischemic stroke, intracranial bleeding or death (OR 0.39, p = .014), and ischemic stroke or myocardial infarction (OR 0.20; p = .002).
Conclusions:
This study shows that pre-interventional statin medication has a protective effect against peri-interventional stroke, MI, or death in patients with internal carotid artery stenosis treated with stent-angioplasty. Accordingly, statins could be considered as a standard pre-interventional medical therapy in carotid stenting.
