Objective: Aneurysmal subarachnoid hemorrhage (SAH) presents a devastating diagnosis for elderly individuals. The clinical value of comorbidities for elderly SAH patients remains unclear. The aim of the study was to analyze the impact of previous medical history and medication on the course of SAH in elderly patients.
Methods: All consecutive SAH cases aged ≥65 years old who were treated in our hospital between 01/2003 and 06/2016 were eligible for this study. The data on comorbidities, previous medication, as well as initial severity, secondary complications of and the outcome after SAH were collected from the electronic medical records. The primary endpoints of the study were: [a] occurrence of cerebral infarcts; [b] in-hospital mortality, and [c] unfavorable outcome at 6 months after SAH defined as modified Rankin scale > 3. The associations were confirmed in the uni-and multivariate analysis.
Results: The final analysis included 246 elderly patients (mean age: 73.6 years, 71.1% females). The rates of cerebral infarcts, in-hospital mortality and unfavorable outcome were 55.6%, 29.7% and 60.2% respectively. Only cardiac morbidity was associated with initial clinical SAH severity, WFNS 4-5 (aOR=1.723, p= 0.046). Of all analyzed secondary complications, only aneurysm re-bleeding (aOR=7.63, p=0.008 / aOR=4.43, p=0.002 / aOR=3.05, p=0.109 for [a], [b] and [c] respectively) and pneumonia (aOR=2.21, p=0.027 / aOR=1.07, p=0.839 / aOR=1.73, p=0.302) were independently associated with one or more of the primary endpoints. In turn, patients with cardiac morbidity were prone to aneurysm re-bleeding (aOR=5.96, p=0.001) and individuals taking the medication with ACE inhibitors were at higher risk of pneumonia (aOR=1.93, p=0.049). The patients with the calcium channel blockers were at higher risk for cerebral infarcts (aOR=2.75, p=0.025). Finally, cardiac morbidity was independently associated with all primary endpoints (aOR=1.95, p=0.048 / aOR=2.25, p=0.014 / aOR=2.71, p=0.027).
Conclusion: Elderly SAH patients are at high risk for poor functional outcome. Particularly, the presence of cardiac comorbidity might complicate the course and outcome of SAH in elderly individuals.
