What is good for heart attacks is still not good enough for brain attacks
| The first 150 words of the full text of this article appear below. |
Therapeutic thrombolysis for acute myocardial
infarction is standard practice, but not so for ischaemic stroke, the
"brain attack" equivalent of heart attack. This is partly because
stroke is more complicated: intracerebral haemorrhage must be excluded by imaging, and more vascular pathologies than atheroma underly ischaemic stroke (for example, intracranial small vessel disease and
embolism from the heart). Furthermore, coronary care units make
research on heart attacks relatively easy, whereas research on acute
stroke still often takes place in general medical wards. With stroke
units, this will be less of a problem. Research on strokes is woefully
underfunded in comparison to research on heart attacks.1
But, if thrombolytic "unblocking the pipes" works for acutely
occluded coronary arteries, it should work for acutely occluded brain
arteries, provided reperfusion does not make matters worse by
increasing cerebral oedema and haemorrhagic transformation. As usual,
the balance of benefit and risk is best determined by
