Symptoms of an Embolic Stroke - Oren Zarif - Embolic Stroke


If you have a family member who has suffered from an embolic stroke, it's important to act quickly. While symptoms may be subtle, a person can experience a sudden onset of inability to move limbs and perform simple manipulations. Symptoms can range from dizziness to altered state of consciousness, and can be accompanied by other symptoms, such as slurred speech and double vision. When you notice these symptoms, call 911 or your local emergency services. The sooner you can get the patient to a medical facility, the more likely the patient will recover.

One-third of ischemic strokes have no known cause. Researchers have proposed the term "Embolic Stroke of Undetermined Source" to describe these events. This new term distinguishes CS from other stroke causes, such as cardiac valve stenosis or large artery atherosclerosis. The study also identified a higher incidence of recurrent embolic stroke in patients with CS. However, a recurrence of an ESUS does not necessarily mean a recurrence of the stroke.

To establish an accurate diagnosis of embolic stroke, a thorough diagnostic evaluation is essential to rule out other causes. Despite the difficulty in determining the underlying cause, some ESUS cases have minimal comorbidities and overwhelmingly specific clinical and diagnostic assessment. In the absence of clear underlying causes, embolic stroke is often misdiagnosed and undertreated. The goal of this study is to identify the underlying pathophysiology of embolic stroke.

When investigating an embolic stroke, cardiac conditions may increase a person's risk of a thrombus. High-risk cardiovascular conditions include atrial fibrillation, a mechanical prosthetic valve, or dilated myocardiopathy. Other risky cardiovascular conditions include mitral rheumatic stenosis, patent foramen ovale, or calcific aortic valve stenosis.

Symptoms of an embolic stroke can vary depending on where in the brain the clot has lodged. It is often difficult to distinguish an embolic stroke from a thrombotic stroke, as the signs of brain hematoma typically appear over several weeks. Some patients may experience a stereotypical TIA episode several times in a row for weeks or months. Atherothrombosis is less severe than an embolic stroke.

An embolic stroke is a life-threatening emergency. The immediate goal of treatment is to restore blood flow to the brain. A catheter is inserted into the arteries and medications that break up clots are used to restore blood flow. Using medications and catheters, emergency medical personnel can quickly restore blood flow to the brain. The sooner you seek medical attention, the sooner you can start a recovery. If you are suffering from an embolic stroke, contact your local emergency room immediately.

In the NAVIGATE-ESUS study, 3 major new findings were observed. First, a significant proportion of patients who had an embolic stroke recurred after ESUS. In fact, in about three-quarters of these patients, no source of embolism could be identified. This study also showed that rivaroxaban prevented atrial fibrillation-related recurrences.
