global study co-led by NUI Galway into causes of stroke has found that one in 11 survivors experienced a period of anger or upset in the one hour leading up to it. One in 20 patients had engaged in heavy physical exertion.
The suspected triggers have been identified as part of the global INTERSTROKE study – the largest research project of its kind, which analysed 13,462 cases of acute stroke, involving patients with a range of ethnic backgrounds in 32 countries, including Ireland.
Stroke prevention is a priority for physicians, and despite advances it remains difficult to predict when a stroke will occur. Many studies have focused on medium to long-term exposures, such as hypertension, obesity or smoking. Our study aimed to look at acute exposures that may act as triggers.
The research analysed patterns in patients who suffered ischemic stroke – the most common type of stroke, which occurs when a blood clot blocks or narrows an artery leading to the brain, and also intracerebral haemorrhage – which is less common and involves bleeding within the brain tissue itself.
The research has been published in the European Heart Journal.
