Cardioembolic stroke, the basis of diagnosis and prevention

Abstract

A stroke develops due to ineffective anticoagulant therapy or the lack of such therapy. With the advent of new oral anticoagulants, everything has changed. This is what the latest research on this topic shows. According to available literature sources, it is known that atherogenic dyslipidemia is a risk factor for plaque failure in the coronary arteries. Persistent atrial fibrillation, diagnosed with Holter's long-term monitoring, is also a risk factor for stroke. One of the methods for diagnosing embolism is transcranial Doppler scanning. Also, the method helps in choosing the tactics of endovascular closure of the left atrial appendage. As for the etiology, embolism is one of the common causes of cardioembolic stroke. The term embolism of an unspecified source (ESUS), a study of the causes currently underway, was introduced for the embolism that happened in the remote period after a myocardial infarction. Recent clinical trials have shown that ESUS can occur in patients with subclinical atrial fibrillation (AF). Evidence suggests that a left atrial thrombus can lead to thromboembolism even in the absence of AF. Many aspects for the sensible management of patients at risk of developing car dioembolic stroke are ref lected in this review.
