文摘

The mortality in intracerebral hemorrhage (ICH) is mainly due to raised intracranial pressure, and its complications mediated by sympathetic overactivity. There is paucity of studies evaluating the role of beta-blockers in the outcome of ICH. This study reports the role of atenolol in reducing mortality, pneumonia, systemic inflammatory response syndrome (SIRS), and 3?months outcome in the patients with hypertensive ICH. 138 consecutive patients with hypertensive ICH were included and their stroke risk factors and clinical details were recorded. Consciousness was assessed by Glasgow Coma Scale and severity of stroke by Canadian Neurological Scale. Volume of hematoma was measures on CT scan and occurrence of SIRS and pneumonia were noted. 3?months outcome was categorized into good (Barthel index >12) and poor (BI?<?12). The patients were categorized into those receiving atenolol and nonatenolol. The effects of atenolol on stroke outcome parameters were evaluated. Seventy-nine patients received atenolol and 59 did not and they mainly received amlodipine. There was no difference in the base line clinical characteristics between the two groups except smoking (P?=?0.01) and baseline blood pressure (P?=?0.007). Atenolol significantly reduced the mortality (11.4 vs 37.3?%, P?<?0.0001), SIRS (16.4 vs 40.9?%, P?=?0.007), and pneumonia (8.9 vs 30.5?%, P?=?0.002) compared to those not receiving atenolol. At 3?months, patients with atenolol had insignificantly better outcome compared to nonatenolol group (49.1 vs 31.9?%, P?=?0.11). Use of atenolol in hypertensive ICH results in reduction in mortality, SIRS, and pneumonia which may be due to its β-adrenergic blocking effect.
