Objective
The number of people over 75 years of age in South Korea is annually increasing. However, there are very
few reports on acute hemorrhagic stroke in elderly patients (aged ≥75 years). The objective of this study was to identify
the characteristics of intracerebral hemorrhage (ICH) in older patients.
Methods
We identified patients aged ≥18 years who were admitted with spontaneous ICH between January 1, 2007
and September 30, 2012. We retrospectively collected demographic characters, risk factors of vascular disease,
and pre-ICH medication history. We analyzed the characteristics (including hematoma volume, location and expansion)
of ICH according to the age of patients.
Results
Of 622 ICH patients, 76 (16.7%) were ≥75 years of age. We found that older age (≥75 years) was significantly
related to a larger hematoma volume (median hematoma volume 12 cc (5-32) in aged <75 years patients versus
median volume 18 cc (12-46) in elderly group, p=0.042) and a greater hematoma expansion (expansion ratio 23.9%
in younger patients versus 40.8% in elderly patients, p=0.002). Initial hematoma volume, hyperglycemia, and a history
of AF (atrial fibrillation), DM(diabetes mellitus) and CKD (chronic kidney disease), were found to be statistically
related to hematoma expansion in patients ≥75 years of age. The most important predictors of ICH expansion in
these patients were hyperglycemia (OR, 0.03; 95% CI, 0.01-0.20; p<0.001) and CKD (OR, 0.15; 95% CI, 0.03-0.80;
p=0.026).
Conclusion
In our study, older age (≥75 years) was significantly related to a larger hematoma volume and a greater
hematoma expansion. Furthermore, hyperglycemia and a history of CKD were important predictors for ICH expansion
in these patients. |
