BACKGROUND: Coronary artery disease (CAD) is a leading cause of long-term mortality in Europe and it negatively influences the outcome after stroke. However, its influence on stroke recurrence which endangers stroke patients mostly in the first months following stroke, is unclear. Previous studies have found no association between CAD and ischemic stroke recurrence. However, assessment of the relationship was not the primary endpoint of these investigations. The aim of this study was to assess the possible association between CAD and stroke recurrence. PATIENTS AND METHODS: In a hospital-based, retrospective study, the set consisted of 190 patients - 105 patients with a first ever stroke (48 males; age 37-88, mean 70.7+/-12.5 years) and 85 patients with stroke recurrence (36 males; age 46-94, mean 88.0+/-9.6 years). CAD was correlated with the following other risk factors (age, sex, occurrence of arterial hypertension, atrial fibrillation, diabetes mellitus, plasma levels of total cholesterol, triglycerides, low-density cholesterol, high-density cholesterol, body mass index, presence of carotid plaques). Logistic regression analysis was used for the statistical evaluation. RESULTS: No significant association was found between CAD and stroke recurrence. Of all of the other observed risk factors, only age showed a significant association with stroke recurrence (OR 1.04, 95% CI: 1.02-1.07). CONCLUSION: The results of the presented study indicate that CAD does not influence stroke recurrence.
