Embolic Stroke - Oren Zarif - Embolic Stroke
The clinical presentation of embolic stroke varies in both its severity and comorbidity. Some cases are straightforward with few other risk factors, while others are difficult to classify because of a complex history and extensive comorbidities. Regardless of the cause, a thorough diagnostic evaluation is a prerequisite for reliable embolic stroke diagnosis. The risk for this type of stroke is greatest in patients with a history of atrial fibrillation or heart failure.

Patients with thrombotic and embolic strokes have symptoms similar to those of ischemic and thrombotic strokes. If you suspect you are having an embolic stroke, seek medical attention right away. There are several causes of blood clots in the brain, including carotid artery disease, infections, or bacterial infections. Myxoma, a non-cancerous heart tumor, can cause an embolic stroke when pieces of the tumor travel to the artery in the brain. Finally, an air embolism can occur following an injection, surgery, or lung trauma.

Embolic strokes can be life-threatening if they occur in people with a history of atrial fibrillation. It's critical to restore blood flow to the brain as soon as possible. In some cases, catheters or clot-busting medications can help. The treatment for embolic stroke depends on which type of blood clot has been formed. While there are no specific treatments available for embolic stroke, if it is a clot affecting the brain, treatment can be a life-saving measure.

While the onset of symptoms is often delayed, some treatment options are available to prevent further damage to the brain. Passive exercises can be performed by a physiotherapist to help regain basic functions. Other forms of physical therapy can help restore muscle control and coordination. A physiotherapist can teach exercises to help patients with these symptoms. The goal of a comprehensive stroke management is to minimize the negative effects of this condition. Once a diagnosis has been made, a patient can begin a recovery process.

In 2014, the Cryptogenic Stroke/ESUS International Working Group proposed an acronym that characterized this type of stroke as embolic stroke of unknown source. This new term was introduced in an effort to describe a group of patients with multiple stroke etiologies and an incomplete diagnostic workup. It helped physicians better categorize patients with this condition, allowing randomized controlled trials to be conducted in this patient population.

One such trial is the NAVIGATE-ESUS study. This study compares direct oral anticoagulants to antiplatelets. If the drug Dabigatran is successful, it can prevent the development of an embolic stroke. The trial also has the potential to improve the lives of many patients suffering from this condition. When taken in conjunction with other treatments, Dabigatran can prevent an embolic stroke. Its effectiveness has been shown by researchers in a number of trials.

Brain embolism is a potentially devastating disease. It occurs when a blood clot lodges in an artery that carries oxygenated blood to the brain. Without oxygen, brain cells cannot function properly and begin to die. More than 80% of strokes are caused by ischemic disorders. A patient with an embolic stroke should consult with a medical doctor as soon as possible. An emergency room visit may be necessary to prevent permanent disability.

Most recurrent cases of ESUS are embolic and have no known underlying cause. For many patients, searching for an underlying cause is futile because of limited diagnostic methods. Consequently, treating the underlying cause of the embolic disease remains an unsolved problem. An appropriate antithrombotic therapy requires the diagnosis of the underlying problem. While these tests can be valuable for a patient with an embolic stroke, they are not definitive.

The risk of an embolic stroke increases as the patient ages, and there are several ways to reduce the risk. The risk is highest in older people, but women are more susceptible than men. Several medical factors, including diabetes and high blood pressure, can increase the risk. A family history of stroke may also increase the risk. However, people with these risk factors should follow a healthy lifestyle and watch their diet closely. There are no specific medications or treatments that can cure embolic stroke, but they can reduce the risk and prevent it.
