Forty-five per cent of patients admitted to hospital for atrial fibrillation (AF) in Australia and New Zealand die within a decade, according to University of Queensland research.
A team led by from 抖阴app官网’s analysed data from more than 250,000 patients admitted for AF and atrial flutter – a closely related condition – to all public and most private hospitals in Australia and New Zealand between 2008 and 2017.
“AF is the most common heart rhythm disorder and the leading cause of heart-related hospitalisations globally, causing symptoms like palpitations, dizziness, and chest pain,” Dr Ngo said.
“The disorder is closely associated with stroke, but we know much less about the risk of recurrent hospitalisations and other consequences such as heart failure or death.
“Unfortunately, we found only 55.2 per cent of patients hospitalised with atrial fibrillation survived beyond a decade.”
Dr Ngo said while some of those deaths were attributable to co-existing conditions, the research showed AF reduced a patient’s life expectancy on average by 2.6 years.
“At 10 years, one in 10 patients had suffered a stroke, one in 6 were hospitalised for heart failure, and 41.2 per cent had been readmitted due to recurrent atrial fibrillation or flutter,” she said.
Co-author and cardiologist from the Prince Charles Hospital said the research revealed at 10 years, less than 7 per cent of patients had catheter ablation procedure, one of the most effective treatments for patients with symptomatic atrial fibrillation.
“It may mean this procedure was underused in Australian and New Zealand hospitals,” Dr Ranasinghe said.
“Clinicians currently primarily focus on preventing the risk of stroke, but these findings emphasise the need to consider atrial fibrillation as a chronic disease with multiple serious downstream consequences.
“There needs to be a greater focus on preventing recurrent hospitalisations and heart failure.
“The literature also suggests many patients at high risk of a stroke fail to receive blood thinning medications, so current preventative efforts are far from ideal.
“Better patient education in areas such as blood pressure control and weight loss, as well as appropriate preventative therapy in hospital and primary care could improve the outcomes for people with AF.”
