Heart failure patients are at higher risk for any type of stroke

Risk of Stroke in Patients With Heart Failure: A Population-Based 30-Year Cohort Study

Adelborg K, Szépligeti S, Sundbøll J, et al. - Stroke. 2017; published online ahead of print

Background

Heart failure (HF) is associated with an increased risk of ischaemic stroke, due to thromboembolic complications and increased activity of pro-coagulant factors. It is also associated with low blood pressure, which may protect against stroke [1]. The role of HF as a risk factor for stroke has not been studied adequately [2-4].

In this study, the short- and long-term risk of ischaemic stroke, intracerebral haemorrhage (ICH) and subarachnoid haemorrhage (SAH) were evaluated in a large cohort of 289 353 HF patients, and compared with 1 446 765 individuals in the general population. Moreover, the influence of comorbidities on the relationship between HF and stroke were assessed.

Main results

Conclusion

In a large cohort study of 30 years, HF was associated with an increased risk of ischaemic stroke, ICH and SAH, especially in the short term, but also in the long term. These findings suggest that HF is an important risk factor for all types of stroke, and that it is important to pay clinical attention to the stroke risk of HF patients.
