The impact of cardiac complications on outcome in the SAH population

Objectives - To determine the impact of cardiac complications (CdCs) on outcomes in patients with acute subarachnoid hemorrhage (SAH). Patients and methods - Eighty-one adult aneurysmal SAH patients with a fisher grade >1 and/or a Hunt and Hess grade >2 were recruited for this study. CdCs were defined as electrocardiogram (ECG) changes, myocardial necrosis, arrythmias, or pulmonary edema. Outcomes were assessed at 3, 6 and 12 months by telephone interview using the Modified Rankin Scale (MRS), Glasgow Outcome Scale (GOS), Barthel Index and Medical Outcome study Short Form-36 (SF-36). Results - The CdCs occurred in 33% of patients. The most common CdCs were arrythmias and pulmonary edema (30%). There was no significant difference in mortality between the two groups. At 3 months there was a significant difference in the Barthel (P = 0.007) and the SF-36 (P = 0.014) with trends in the GOS (P = 0.049) and the MRS (P = 0.063). At 6 months a significant difference remained in the SF-36 (P = 0.028) and a trend in the Barthel (P = 0.069). Conclusion - Results show that CdCs may negatively impact outcomes in SAH patients up to 6 months following hemorrhage.
