Objectives: We hypothesized that long-term morbidity and mortality can be identified by the presence of comorbidities in patients with carotid artery stenosis. In our study we aimed to investigate the relationship between clinical characteristics, laboratory findings and long-term prognosis in carotid artery stenosis patients after stenting

Patients and Methods: We retrospectively enrolled 212 patients whom underwent carotid artery stenting (CAS) between January 2010 and December 2012 at Kartal-Kosuyolu Training and Research Hospital. CAS was performed in symptomatic patients with >60% stenosis and in asymptomatic patients with >80% stenosis of extracranial carotid artery. Symptoms were defined by an ipsilateral cerebral or ocular minor or major ischemic event within the past 6 months.

Results: Mean age of study population was 67.4 ± 7.9 years and 158 patients (74.5%) were male. In the follow-up period 18 patients had MI, 18 patients had major stroke, 23 patients had transient ischemic attack. Twenty-one patients (9.9%) died from cerebral-cardiovascular causes. All MACCE was found in 64 patients (30.2%). Multivariate analysis revealed that age (OR: 1.09, 95% CI: 1.02-1.17, p = 0.05), heart failure (OR: 3.78, 95% CI: 1.48-9.62, p = 0.005), creatinine (OR: 3.54, 95% CI: 1.16-10.82, p=0.026) and neutrophil-lymphocyte ratio (OR: 2.88, 95% CI: 1.90-4.36, p < 0.0001) were independent predictors of the MACCE.

Conclusion: Although, the short-term risk of patients undergoing CAS dominated by lesion-related factors, pre-existing comorbidities may be even more important for the long-term event. Age, heart failure, creatinine and neutrophil-lymphocyte ratio were found as the most important risk factors of MACCE.
