Anticoagulants could have decreased stroke risk

When Valerie Haigh was diagnosed, aged 64, with the heart rhythm disorder atrial fibrillation (AF), her cardiologist assured her it wasn’t daily life-threatening. “My symptoms incorporated dizziness and a rapidly racing heart,” says the retired secretary, 75 (pictured, proper) from New Malden, south-west London.

AF occurs when the upper chambers of the heart contract randomly, creating an irregular, occasionally abnormally quickly, heart charge. This permits blood to pool in the heart, potentially forming clots, which can result in a stroke if they travel to the brain. The National Institute for Overall health and Care Excellence (Good) has advisable anticoagulant therapy such as warfarin to minimize danger of clots in AF patients given that 2006.

Final year, the Royal University of Doctors found that a quarter of AF sufferers admitted to hospital with strokes have been on no preventative medication at all, and 38 per cent were only taking aspirin. “While aspirin might be adequate for healthy AF patients in their forties, it lowers AF-connected stroke danger by only 19 per cent, compared with warfarin at 64 per cent, so is not ample for most AF patients,” says Prof Cowie.

Glyn Davies MP, Chair of the All Get together Parliamentary Group on Atrial Fibrillation which sponsored the report, says: “People are dying unnecessarily and others’ lives are ruined. And stroke care is really costly for the NHS.”

Concern about side-effects is a single reason doctors shy away from prescribing anticoagulants, believes Prof Cowie. “They overestimate the risk of anticoagulation, and underestimate the danger of stroke,” he says. “In any situation, aspirin carries the identical bleeding risk as warfarin.” For individuals who struggle on warfarin, he says, there are great choices named novel anticoagulant medication (NOACs), this kind of as rivaroxaban (Xarelto) and dabigatran (Pradaxa).

“These medication are simpler to handle, but doctors are not discussing them with sufferers. Only three.four per cent of AF patients are taking NOACs – Great forecast twenty per cent would be on them by now.”

Up to half of AF situations are undiagnosed. “AF can result in evident signs and symptoms such as a racing heart, but numerous have no clear signs nevertheless are still at threat of stroke,” says Prof Cowie. “If you are above 45, check out your pulse. If it is often irregular and skipping about, see your GP.”
