Cerebral ischemic attacks as a complication of heart disease: the value of echocardiography
Insights
Echocardiography effectively detects heart disease in patients with transient ischemic attacks or stroke, identifying potential sources of embolism missed by other methods. This cardiac imaging is crucial for stroke prevention strategies.
Area of Science:
- Cardiology
- Neurology
- Medical Imaging
Background:
- Cerebral ischemic attacks (TIA) and stroke are often linked to cardiac conditions.
- Identifying cardiac sources of embolism is vital for preventing recurrent cerebrovascular events.
- Traditional diagnostic methods may not detect all relevant cardiac abnormalities.
Purpose of the Study:
- To investigate the association between heart disease and ischemic cerebrovascular events.
- To evaluate the utility of echocardiography in identifying cardiac pathology and embolic sources in these patients.
- To determine the prevalence of cardiac disorders not detectable by clinical examination or electrocardiography.
Main Methods:
- A study involving 194 patients diagnosed with transient cerebral ischemic attack or stroke.
- Echocardiography was performed to assess cardiac structure and function.
- Clinical examination and electrocardiography were used as comparative diagnostic tools.
Main Results:
- Heart disease was identified in 95 out of 194 patients.
- Echocardiography revealed positive findings in 63 patients with heart disease.
- Cardiac disorders, including aortic and mitral valve disease, were detected by echocardiography in 25 patients, missed by other methods.
- Heart disease was considered a probable source of systemic embolism in 35 patients.
Conclusions:
- Echocardiography is a valuable tool for detecting heart disease in patients experiencing transient ischemic attacks or stroke.
- This imaging modality significantly contributes to identifying potential embolic sources.
- Echocardiography uncovers cardiac conditions not apparent through standard clinical assessment or electrocardiography, aiding in stroke risk stratification and management.
Abstract:
The association of heart disease and cerebral ischemic attacks, and the usefulness of echocardiography in detecting heart disease and possible embolic source, were studied in 194 patients with transitory cerebral ischemic attack or stroke. The study revealed 95 patients with heart disease, and 63 of them had positive echocardiographic findings. All together, 35 patients had heart disease as a probable source for systemic embolism. An undetected cardiac disorder, not found by clinical examination or electrocardiography, was detected in 25 patients. The cardiac disorder found by echocardiography only, was most frequently aortic and mitral valve disease. Thus, echocardiography is an useful tool in detecting heart disease in these patients.
