Abstract

BACKGROUND: symptomatic intracerebral haemorrhage (ICH) is a major concern of intravenous thrombolysis (IVT) for ischaemic stroke. Asians are considered more vulnerable to ICH than non-Asians. Reports on safety of IVT for Asian octogenarians and nonagenarians are limited.

AIMS: the aims of our study were to compare the safety of IVT between octogenarians and nonagenarians and between Asian and Western patients.

METHODS: patients receiving IVT for ischaemic stroke were prospectively registered from four hospitals in Taiwan. Octogenarians and nonagenarians were recruited for analysis. The primary safety outcome measure was symptomatic ICH. The secondary outcome measure was 3-month mortality. We searched the literature on IVT for ischaemic stroke for comparison.

RESULTS: from January 2007 to December 2012, a total of 186 (18.3%) ischaemic stroke patients aged 80 and older, including 166 octogenarians and 20 nonagenarians, were recruited from 1,018 patients receiving IVT. Nine (4.8%) of recruited patients had symptomatic ICH, all in the octogenarian group (5.4%). Three-month mortality was 14.1% in recruited patients and without difference between the two age groups (P = 0.558). The results were comparable with reports on Western octogenarians and nonagenarians in the literature.

CONCLUSION: octogenarians and nonagenarians receiving IVT have a similar safety outcome. Asian octogenarians and nonagenarians receiving IVT for ischaemic stroke are not at higher risk of symptomatic ICH and mortality than Western patients.
