Cardioembolism is responsible for nearly 30% of the origins of ischemic stroke. <jats:italic>Methods.<\/jats:italic> We analyzed data of 256 patients with cardioembolic ischemic stroke (according to TOAST classification) who were admitted into the Hospital S\u00e3o Lucas-PUCRS from October 2011 to January 2014. The cardioembolic subtype was divided into six subgroups: arrhythmias, valvular heart disease, coronary artery disease, cardiomyopathy, septal abnormalities, and intracardiac injuries. The prevalence of the most important cardiovascular risk factors and medications in use for prevention of systemic embolism by the time of hospital admission was analyzed in each patient. <jats:italic>Results.<\/jats:italic> Among 256 patients aged 60.2 +\/\u2212 6.9 years, 132 males, arrhythmias were the most common cause of cardioembolism corresponding to 50.7%, followed by valvular heart disease (17.5%) and coronary artery disease (16%). Hypertension (61.7%) and dyslipidemia (43.7%) were the most common risk factors. Less than 50% of patients with arrhythmias were using oral anticoagulants. <jats:italic>Conclusions.<\/jats:italic> Identifying the prevalence of cardioembolic stroke sources subgroups has become an increasingly important role since the introduction of new oral anticoagulants. In this study, arrhythmias (especially atrial fibrillation) were the main cause of cardioembolism.<\/jats:p>","DOI":"10.1155\/2014\/753780","type":"journal-article","created":{"date-parts":[[2014,10,2]],"date-time":"2014-10-02T21:03:18Z","timestamp":1412283798000},"page":"1-4","source":"Crossref","is-referenced-by-count":2,"title":["Cardioembolic
