Insights
Older patients (≥75 years) undergoing carotid artery stenting (CAS) face higher risks of adverse events. However, age did not impact outcomes for asymptomatic patients or stroke risk post-procedure.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Geriatric Medicine
Background:
- The real-world, age-dependent outcomes of carotid artery stenting (CAS) are not well-established.
- This study evaluates acute and long-term results of CAS across different age groups in a single-center registry.
Purpose of the Study:
- To assess the impact of age on the outcomes of carotid artery stenting (CAS).
- To compare acute and long-term results of CAS in patients stratified by age (<65, 65-74, and ≥75 years).
Main Methods:
- A consecutive series of 878 patients undergoing CAS between 1999 and 2015 were analyzed.
- Patients were categorized into three age groups: <65, 65-74, and ≥75 years.
- Outcomes included a composite of 30-day death, stroke, myocardial infarction (MACCE), and long-term ipsilateral stroke.
Main Results:
- Patients aged ≥75 years had a significantly higher rate of the primary endpoint (MACCE plus long-term ipsilateral stroke) compared to the 65-74 age group (HR 2.30, P=0.001).
- The stroke endpoint was also higher in the ≥75 group versus the 65-74 group (HR 2.03, P=0.04).
- No significant age-dependent differences were observed in asymptomatic patients or for stroke risk beyond the periprocedural period.
Conclusions:
- Older patients (≥75 years) experience poorer outcomes following CAS.
- Age is not a significant factor in outcomes for asymptomatic patients undergoing CAS.
- The risk of stroke beyond the periprocedural period is not influenced by patient age.
Background:
The age-dependent outcome of carotid artery stenting (CAS) outside of randomized controlled trials is largely unknown. Therefore, we assessed acute and long-term results of CAS in a single-center real-world registry.
Methods:
All symptomatic and asymptomatic patients who consecutively underwent CAS were enrolled into the present analysis. The population was divided into three groups dependent on patients' age (<65, 65-74, and ≥75 years).
Results:
Between 1999 and 2015, a total of 878 patients (24%, <65 years; 40%, 65-74 years; and 36%, ≥75 years) underwent CAS. The rate of the primary endpoint (30-day composite of death, stroke, and myocardial infarction [MACCE] plus long-term ipsilateral stroke) was higher in patients aged ≥75 years compared to the middle-age group (hazard ratio [HR] 2.30, confidence interval [CI] 1.22-4.36; P = 0.001). Similarly, the rate of the stroke endpoint (30-day any stroke plus long-term ipsilateral stroke) was higher in patients aged ≥75 years compared to patients aged 65-74 years (HR 2.03, CI 1.01-4.10; P = 0.04). There was no significant age-dependent difference of the primary endpoint and stroke endpoint in the subset of asymptomatic patients. Furthermore, age had no influence on the risk of stroke beyond the periprocedural period.
Conclusions:
Patients aged ≥75 years had poorer outcomes after CAS compared to younger patients. Importantly, age did not influence the outcome in asymptomatic patients and the risk for stroke beyond the periprocedural period.
