English: Thank you for the question. I recognise atrial fibrillation is a significant risk in people who have strokes. The latest sentinel stroke national audit programme clinical audit showed that 18 per cent of Welsh stroke patients had atrial fibrillation prior to their stroke. We already have work going on in this area. In the previous statement I made in this place on stroke and stroke improvement, I noted the University Hospital of Wales-led Stop a Stroke project. That was specifically about consultants working with the third sector, the British Heart Foundation, NWIS and Public Health Wales to look at how you have appropriate treatment for people with atrial fibrillation to reduce their risk of stroke, but also about the proactive offer in looking to find out who has untreated and undiagnosed atrial fibrillation. To date, 40 per cent of atrial fibrillation patients were not on the appropriate treatment and could be anti-coagulated to reduce their risk of stroke. So, there is work that's already ongoing. That work now, following the pilot in the University of Wales Hospital, is being rolled out across the country. This is one of the risk factors we could and should control, but of course there are many others. The big public health challenges of smoking, overuse of alcohol, our diet and not exercising enough all have significant impacts on our risk of a range of conditions, including, of course, stroke. If we can do more as a country to change our behaviour, we'll have fewer people suffering ill health in the first place in stroke and a range of other areas.
Welsh: Diolch i chi am y cwestiwn. Rwy'n cydnabod bod ffibriliad atrïaidd yn risg sylweddol mewn pobl sy'n cael strôc. Roedd archwiliad clinigol diweddaraf y rhaglen archwilio genedlaethol ar gyfer sentinel strôc yn dangos bod gan 18 y cant o gleifion strôc Cymru ffibriliad atrïaidd cyn eu strôc. Mae gennym eisoes waith ar y gweill yn y maes hwn. Yn y datganiad blaenorol a wneuthum yn y lle hwn ar strôc a gwella strôc, crybwyllais y prosiect Atal Strôc a arweinir gan Ysbyty Athrofaol Cymru. Roedd hwnnw'n ymwneud yn benodol ag ymgynghorwyr yn gweithio gyda'r trydydd sector, Sefydliad Prydeinig y Galon, Gwasanaeth Gwybodeg GIG Cymru ac Iechyd Cyhoeddus Cymru i edrych ar sut y mae gennych driniaeth briodol ar gyfer pobl sydd â ffibriliad atrïaidd i leihau eu risg o gael strôc, ond mae hefyd yn ymwneud â'r cynnig rhagweithiol i geisio darganfod pwy sydd â ffibriliad atrïaidd heb ei drin a heb ddiagnosis. Hyd yma, nid oedd 40 y cant o gleifion ffibriliad atrïaidd yn cael y driniaeth briodol a gallent fod wedi cael meddyginiaeth wrth-geulo i leihau eu risg o gael strôc. Felly, mae gwaith eisoes ar y gweill. Mae'r gwaith hwnnw yn awr, yn dilyn y cynllun peilot yn Ysbyty Athrofaol Cymru, yn cael ei gyflwyno ledled y wlad. Dyma un o'r ffactorau risg y gallem ac y dylem ei reoli, ond wrth gwrs mae llawer o rai eraill. Mae'r heriau mawr sy'n wynebu iechyd cyhoeddus megis ysmygu, goryfed alcohol, ein deiet a diffyg ymarfer corff i gyd yn gallu cael effaith sylweddol ar ein risg o amrywiaeth o gyflyrau, gan gynnwys strôc wrth gwrs. Os gallwn wneud mwy fel gwlad i newid ein hymddygiad, bydd gennym lai o bobl yn dioddef iechyd gwael yn y lle cyntaf mewn perthynas â strôc ac amrywiaeth o feysydd eraill.
