Objective: In Spain occurs about 120,000 strokes per year. Initial study usually requires echocardiography to rule out cardioembolic source. We describe most common echocardiographic features in neurological patients and traditional risk factors in them. Methods: From August 2020 to August 2021, 502 consecutive Neurology echocardiograms were analysed, collecting data in SPSS for subsequent descriptive and analytical statistical analysis. Results: 45% were women. Most frequent study reason was ischemic stroke (66%), followed by transient ischemic attack (TIA) (11%), haemorrhagic stroke (2%) and miscellaneous (fever, cardiac enzyme release, dyspnoea, coma) (15%). Highest frequent risk factor was hypertension (HBP) (70%), followed by obesity (51%), dyslipidaemia (46%), diabetes (32%), and kidney failure (15%). Atrial fibrillation (AF) had been documented in 13%, while De novo AF was discovered in an additional 14.5%. Systemic inflammation disorders were present in 19% and hypercoagulability in 9%. 10% had suffered a previous stroke (90% ischemic), and 2.6% TIA. About treatment 27% had antiaggregation drugs on stroke moment and 12% were anticoagulated (5.6% VKA and 6.6% DOAC). In echo images, absence of structural heart disease was the most frequent finding (49%), followed by LA dilatation (48%) and ventricular hypertrophy > 13 mm (34%), both characteristic of hypertensive heart. 5% showed valve disease (more frequent mitral regurgitation) and 5% Cor pulmonale. Cardiomyopathy was found in 3% (Dilated 2.6%). Patent foramen ovale, and aneurysm of the interatrial septum were rare (1% each). Ostium secundum type ASD only one case (0.2%). In the follow-up 5% had a new event (stroke or TIA) in next 12 months and additional 4.4% evidence of AF was found, this variable being related to left atrial dilatation in statistical analysis. Conclusions: In our sample of patients with ischemic stroke the abnormal finding most recurrent was hypertensive heart disease (HBP, LA dilatation, and LVH). LA dilation was related to the development of AF during follow-up, this relationship being statistically significant (p < 0.001) by chi-square test. The percentage of de novo AF discovered in the same stroke episode (14.5%) is noteworthy. The ineffectiveness of antiaggregation (27% took it) and that anticoagulation does not completely eliminate risk either. Presence of structural anomalies such ASD, PFO or thrombus was rare (less than 1%).
