There is increasing evidence that left atrial dysfunction or cardiopathy is associated with ischemic stroke risk independently of atrial fibrillation. We aimed to determine the prevalence of atrial cardiopathy biomarkers in patients with cryptogenic stroke. We included consecutive patients with ischemic stroke enrolled in the New York Columbia Collaborative Specialized Program of Translational Research in Acute Stroke registry between December 1st, 2008 and April 30th, 2012. Medical records were reviewed and patients with a diagnosis of cryptogenic stroke were identified. Atrial cardiopathy was defined as at least one of the following: serum N- terminal pro brain natriuretic peptide (NT pro-BNP)>250 pg/mL, P-wave terminal force velocity in lead V1 on electrocardiogram (PTFV1) >5000 μV*ms, or severe left atrial enlargement (LAE) on echocardiogram. We compared clinical, echocardiographic, and radiological characteristics between patients with and without atrial cardiopathy. Among 40 patients with cryptogenic stroke, 63% had at least one of the biomarkers of atrial cardiopathy; 49% had elevated NT-proBNP, 20% had evidence of increased PTFV1 on ECG, and 5% had severe LAE. Patients with atrial cardiopathy were more likely to be older (76 vs. 62 years; p=0.012); have hypertension (96% vs. 33%, p<0.001), hyperlipidemia (60% vs. 27%, p=0.05), or coronary heart disease (28% vs. 0%, p=0.033), and less likely to have a patent foramen ovale(4% vs. 40%, p=0.007). There is a high prevalence of biomarkers indicative of atrial cardiopathy in patients with cryptogenic stroke. Clinical trials are needed to determine whether these patients may benefit from anticoagulation to prevent stroke.
