Summary
Diastolic dysfunction (DD) and systolic dysfunction (SD) were observed in patients with subarachnoid hemorrhage (SAH). These biventricular myocardial dysfunctions may cause hemodynamic instability and pulmonary edema after SAH.
Area of Science:
- Cardiology
- Neurology
- Critical Care Medicine
Background:
- Diastolic dysfunction (DD) is increasingly recognized as a factor in hemodynamic instability and pulmonary edema.
- The role of DD and systolic dysfunction (SD) in subarachnoid hemorrhage (SAH) patients remains undescribed.
Observation:
- Three patients with aneurysmal SAH presented with hemodynamic instability and pulmonary edema.
- Transesophageal echocardiography was performed during aneurysm surgery.
Findings:
- Patients exhibited mild to severe left ventricular systolic and diastolic dysfunction (SD and DD).
- Right ventricular systolic and diastolic dysfunction (SD and DD) were also documented.
- Biventricular myocardial dysfunctions were present in all observed cases.
Implications:
- Biventricular systolic and diastolic myocardial dysfunctions may contribute to hemodynamic instability post-SAH.
- These cardiac dysfunctions could play a role in the development of pulmonary edema following SAH.
- Further research is warranted to elucidate the mechanisms linking SAH to biventricular dysfunction.
