| Popis: | The use of insertable cardiac monitors (ICM) has increased the rate of detection of atrial fibrillation (AF) among cryptogenic stroke (CS) patients. We describe a single-center experience for AF detection among CS patients receiving ICMs upon discharge after the index stroke event and attempt to identify predictors for AF detection.From April 2014 to October 2017, patients receiving ICMs for CS who underwent60 days of monitoring were reviewed. Chronic underlying medical illnesses, presence of left atrial enlargement (LAE) on echocardiography, and PR interval on admission electrocardiogram were assessed as predictors of AF detection.A total of 234 patients (median age 72 [61, 78] years, 45% women) met inclusion criteria and were followed for a median of 536 [282, 848] days. Among studied patients, 68 patients (29%) were found to have AF at a median of 94.5 [16, 239] days from ICM placement. CS patients with AF were significantly older (p 0.001), and there was a significantly higher proportion of women (p = 0.003) when compared to CS patients without AF. Neither presence of LAE nor prolonged PR interval was predictive of AF detection.Almost one-third of CS patients monitored with an ICM were found to have previously undiagnosed AF. CS patients found to have AF were older and more commonly women. Prospective studies are needed to better identify predictors for early AF among the broader population of all CS patients. |
