Common heart rhythm abnormality along with other health conditions linked to greater risk of mortality

Young or middle-aged people with Atrial Fibrillation (AF), the most common heart rhythm abnormality, are at greater risk of death if they have other long-term health conditions, according to a new study.

The research, led by the University of Glasgow and published today in Europace, has suggested that AF patients, who also have other health conditions, should be prioritized for healthcare interventions.

The study used UK Biobank data to examine the problem of having multimorbidity (two or more long-term health conditions) for those who also have AF. It found that young or middle-aged people in this group were at an increased risk of death over a follow-up period of between 5 and 10 years.

Patients with AF who also had four or more long-term health conditions were six times more likely to die than those without any long-term conditions.

Authors of the study have suggested that patients with AF and other long terms conditions should be prioritized for higher levels of monitoring and offered health interventions to aid with treatment, and in some cases to adjust their lifestyle in order to reduce the impact of their conditions.

Lead author of the study, Frances Mair, Norie Miller Professor of General Practice from the University of Glasgow, said:

We have shown that young and middle-aged patients with atrial fibrillation and one or more other long chronic illnesses are at increased risk of death over a follow-up period of 5-10 years.

This suggests that these patients should be prioritized for interventions to enhance their adherence to treatment, and in some cases to adjust their lifestyle in order to reduce the impact of their other chronic illnesses (comorbidities) on survival.

The study looked at 3651 participants with Atrial Fibrillation and examined the impact of other long-term conditions on their health. Presence of other conditions such as chronic obstructive pulmonary disease (COPD) and osteoporosis were associated with a significantly higher risk of mortality.

Dr. Bhautesh Jani, NRS Career Research Fellow, said:

Future clinical guidelines for AF need to take greater account of co-morbidity.  Young and middle-aged patients with AF and multiple co-morbidities may need closer monitoring by health professionals as they are at higher risk of dying.

Atrial Fibrillation is the most common sustained heart rhythm abnormality, affecting an estimated 33 million people worldwide. The prevalence of AF is increasing globally, partly attributable to improved surveillance and the increasing prevalence of lifestyle-related cardiovascular disease risk factors.
