Early Rhythm Control in Patients With Incident Atrial Fibrillation Who Had a Prior Stroke

Adherence to an integrated care pathway for stroke is associated with lower risk of major cardiovascular events: A report from the Athens Stroke Registry

BACKGROUND

A recent European Society of Cardiology (ESC) Council on Stroke position paper proposed a holistic integrated care management approach for stroke patients, to improve cardiovascular outcomes. The impact of implementing the ABCstroke pathway 'concept' on clinical outcomes has never been estimated before. In order to investigate the potential effect of ABCstroke pathway adherence to cardiovascular outcomes post stroke, we performed a post-hoc analysis from the Athens Stroke Registry.

METHODS AND RESULTS

This analysis was performed in the Athens Stroke Registry, which includes all consecutive patients with acute first-ever ischemic stroke. The Kaplan-Meier product limit was used to estimate the cumulative hazard of each outcome according to adherence with the ABCstroke pathway. We studied 2513 patients [median (IQR) age 71 (62-78) years; 37.7 % female] with ischemic stroke with median follow-up period of 30 (6-75) months. Full adherence to the ABC pathway was identified in 156 (6.2 %) of the patients, while 192 (7.6 %) did not adhere to any of the therapeutic pillars of ABCstroke. Full adherence to ABC treatment pathway was associated with significant reduction of stroke recurrence, compared to patients with no or partial adherence (aHR: 0.61; 95 %CI: 0.37-0.99), as well as a lower risk of MACE (HR: 0.59; 0.39-0.88) and death (aHR: 0.22; 95 %CI: 0.12-0.41).

CONCLUSION

Full adherence to the ABCstroke pathway based on the current guidelines was evident in only 6.2 % of our ischaemic stroke cohort but was independently associated with lower risks of stroke recurrence, major cardiovascular events and mortality. This highlights a potential opportunity to improve clinical outcomes post-stroke with a holistic or integrated care management approach.

Current practice and attitudes of stroke physicians towards rhythm-control therapy for stroke prevention: results of an international survey

BACKGROUND

Patients with ischemic stroke and atrial fibrillation (AF) are at particularly high risk for recurrent stroke and cardiovascular events. Early rhythm control has been shown to be superior to usual care for the prevention of stroke and cardiovascular events for people with early AF. There are no data on the willingness to use rhythm control for patients with AF and acute ischemic stroke in clinical practice.

METHODS

An online survey was carried out among stroke physicians to assess current practice and attitudes toward rhythm control in patients with AF and acute ischemic stroke between December 22nd 2021 and March 24th 2022.

RESULTS

The survey was completed by 277 physicians including 237 from 15 known countries and 40 from unspecified countries. 79% (210/266) reported that they do not regularly apply treatment for rhythm control by ablation or antiarrhythmic drugs at all or only in small numbers (≤ 10%) of patients with AF and acute ischemic stroke. In those patients treated with rhythm-control therapy, antiarrhythmic drugs were used by the majority of respondents (89%), while only a minority reported using AF ablation (11%). 88% of respondents (221/250) stated that they would be willing to randomize patients with AF after acute ischemic stroke to either early rhythm control or usual care in a clinical trial.

CONCLUSION

Despite its potential benefit, few patients with AF and acute ischemic stroke appear to be treated with rhythm control, which may result from uncertainty regarding potential complications of antiarrhythmic therapy in patients with acute stroke. Together with recent data on the effectiveness of early rhythm control in patients with a history of stroke, these results call for a randomized clinical trial to assess the efficacy of early rhythm control in patients with acute ischemic stroke and AF.
