Stroke recurrence largely depends on the detection of the cause and the control of vascular risk factors, with occult atrial fibrillation (AF) being one of the most important. Prolonged ambulatory cardiac monitoring is recommended for detecting occult AF. Currently, there are non-invasive monitoring devices such as the textile Holter that have proven to be useful for monitoring for up to 30 days but not longer. Another alternative is smartwatches, although they must be validated for use in the elderly population who have had a stroke.

Primary | Increased probability of detecting AF | To identify and compare prevalence rates of AF detection for the purpose of determine the clinical relevance or not of a prolonged screening process for AF. On the intervention group, patients will have a cardiac monitoring for up to 12 months. If AF is detected by ECG smartwatch, the ICM data will be analyzed by a cardiologist team and provide an ECG report to investigators in order to confirmed ECG smartwatch result. | Assessed throughout 1 year trial period | |
Secondary | Identification of Atrial Fibrillation using a ECG smartwatch | Episodes of atrial fibrillation detected by the ECG smartwatch will be compared to the gold-standard cardiac monitor | Assessed throughout 1 year trial period | |
Secondary | Usability and adherence to ECG Smartwatch | To evaluate the usability to the use of the ECG Smartwatch through the System usability scale (SUS) and self-reported of likes or dislikes encountered with wearable. | Assessed throughout 1 year trial period | |
Secondary | Control of vascular risk factors (VRF) | To describe and compare the percentage of adequate control of VRFs among patients in each study group. VRFs metrics are defined according to the AHA Life Simple 7 factors. Ideal metrics were defined as follows: (1) Smoking status: never or former smoker; (2) BMI: <25 kg/m2; (3) Physical activity: =150 min/wk of moderate-intensity physical activity; (4) Healthy diet: 4 or 5 fruits/vegetables per day; (5) Total cholesterol <200 mg/dL; (6) Blood pressure <120/80 mm Hg; (7) Fasting glucose <100 mg/dL. | Assessed at the end of the 1 and 2 year trial period | |
Secondary | Vascular events incidence | To describe the vascular events defined as recurrence of stroke, the incidence of cerebral hemorrhage, heart failure, myocardial infarction, or vascular death in each study group | Assessed at the end of the 1 and 2 year trial period | |
Secondary | Predictors of vascular recurrence | To identify predictors of vascular recurrence (recurrent stroke, cerebral hemorrhage, heart failure, myocardial infarction, or vascular death) in each study group. Predictors of vascular recurrence included sociodemographic data such as age, sex and education level; BMI (kg/m2); history of diabetes mellitus; LDL-cholesterol and medications, such as the use of anti-hypertensive medications, lipid-lowering medications, and antiplatelet therapy. Also clinical symptoms, neuroimagen and ECG parameters will be included in the analysis. | Assessed at the end of the 1 and 2 year trial period |
