Subarachnoid hemorrhage can cause myocardial dysfunction and cardiogenic shock, mimicking heart attacks. Prompt diagnosis and hemodynamic stabilization are crucial for improving outcomes and reducing cerebral ischemia risk.
Area of Science:
- Neurology
- Cardiology
- Critical Care Medicine
Background:
- Systemic complications are common in subarachnoid hemorrhage (SAH) patients.
- Electrocardiographic abnormalities mimicking ischemic cardiomyopathy can occur, linked to myocardial dysfunction.
Purpose of the Study:
- To report a case of SAH associated with myocardial dysfunction and cardiogenic shock.
- To highlight the importance of diagnosis and hemodynamic management in such cases.
Main Methods:
- Case report of a 45-year-old female with SAH, coma, and subsequent cardiogenic shock.
- Inclusion of diagnostic tests: ECG, cardiac enzymes, cardiac index, systemic vascular resistance, ejection fraction, coronariography, and transcranial Doppler.
- Management involved aneurysm embolization, respiratory support, and dobutamine infusion.
Main Results:
- The patient presented with SAH, coma, pulmonary infiltration, dyspnea, hypotension, ECG changes, and elevated CK-MB.
- Cardiogenic shock was diagnosed based on low cardiac index and unresponsiveness to volume.
- Coronary angiography was normal; ejection fraction improved from 39% to 65% after treatment.
Conclusions:
- SAH can lead to ventricular dysfunction and cardiogenic shock, increasing cerebral ischemia risk.
- Optimizing diagnosis and hemodynamic stabilization are essential for managing SAH complications.
- Early intervention can improve cardiac function and reduce secondary neurological injury.
