[Cerebral circulatory disorders in patients with cardiovascular diseases accompanied by cardiac rhythm disorders]
Insights
Cerebral circulation disorders are more common in patients with permanent cardiac fibrillation, especially when combined with ventricular extrasystoles. This study highlights the link between heart rhythm disturbances and cerebrovascular events.
Area of Science:
- Cardiology
- Neurology
- Vascular Medicine
Context:
- Cerebrovascular disorders often occur alongside various heart rhythm disturbances.
- Patients studied had underlying conditions like rheumatic heart disease, hypertensive disease, or atherosclerosis with ischemic heart disease.
- A control group of 100 patients without heart rhythm disturbances was included for comparison.
Purpose:
- To investigate the correlation between different types of heart rhythm disturbances and the occurrence and severity of cerebral circulation disorders.
- To compare the incidence of cerebrovascular events in patients with and without cardiac arrhythmias.
Summary:
- 180 patients with cerebral circulation disorders and concomitant heart rhythm disturbances were analyzed.
- Permanent forms of cardiac fibrillation were associated with a higher frequency of cerebral circulation disorders compared to paroxysmal forms and extrasystoles.
- The most severe cerebrovascular complications were observed in patients with rheumatic heart disease experiencing permanent cardiac fibrillation combined with ventricular extrasystoles.
Impact:
- Findings underscore the critical role of managing heart rhythm in preventing and treating cerebrovascular events.
- Highlights specific arrhythmias, like permanent cardiac fibrillation with extrasystoles, as high-risk factors for severe cerebral circulation disorders.
- Informs clinical practice regarding risk stratification and therapeutic strategies for patients with combined cardiovascular and cerebrovascular conditions.
Abstract:
The authors examined 180 patients where disorders of cerebral circulation developed on the background of different disturbance of the heart rhythm. The patients suffered from rheumatic heart disease, hypertensive disease or atherosclerosis in concomitance with ischemic heart disease. For comparison, 100 patients with similar disorders were studied, but without disturbances of heart rhythm. It was established that disorders of cerebral circulation were more frequently seen in permanent forms of cardiac fibrillation and less so in paroxysmal cardiac fibrillation and extrasystoles. The most severe disorders of cerebral circulation were seen in combinations of permanent forms of cardiac fibrillation with single and frequent ventricular extrasystoles in patients with rheumatic heart disease.
