Key result
Newly diagnosed atrial fibrillation after acute ischemic stroke shares similar cardiovascular risk factors and echocardiographic findings with known AF, indicating preexisting heart disease.
Why the study?
Do acute ischemic stroke patients with newly diagnosed AF have similar cardiovascular risk factors and echocardiographic parameters compared to those with known AF?
Population
1,397 consecutive acute ischemic stroke patients with echocardiography data (median age 71, 62.3% male).
Comparison
Newly diagnosed atrial fibrillation (nAF) vs Known atrial fibrillation and no atrial…

Do acute ischemic stroke patients with newly diagnosed AF have similar cardiovascular risk factors and echocardiographic parameters compared to those with known AF?
Newly diagnosed atrial fibrillation after acute ischemic stroke shares similar cardiovascular and echocardiographic profiles with known AF, suggesting it is primarily driven by preexisting heart disease rather than acute neurogenic triggers.
Rizos et al. (2016) conducted a cohort in Acute ischemic stroke (n=1,397). Newly diagnosed atrial fibrillation vs. Known atrial fibrillation and no atrial fibrillation was evaluated on Clinical characteristics and echocardiographic findings. Newly diagnosed atrial fibrillation after acute ischemic stroke shares similar cardiovascular risk factors and echocardiographic findings with known AF, indicating preexisting heart disease.
