Causes of Embolic Stroke - Oren Zarif - Embolic Stroke
An embolic stroke is a type of acute cerebral infarction with a high risk of mortality and morbidity. It should be diagnosed in its acute phase and treated promptly for secondary prevention. This activity reviews the clinical evaluation, the use of neuroimaging, and other investigations, and emphasizes the importance of an interprofessional team when evaluating a patient with suspected embolic stroke. It summarizes the causes of embolic stroke and its management.

ESUS is less straightforward to diagnose than other types of stroke, and it often occurs in patients who have several pathologies. Typical causes include aortic arch or carotid atherosclerosis, left ventricular dysfunction, aortic valve disease, and supraventricular tachycardia. However, there is no single cause of embolic stroke, and there is no way to rule out any one factor.

In order to make a definitive diagnosis of embolic stroke, doctors must perform a comprehensive diagnostic evaluation to rule out other causes of the disease. While some cases may be straightforward, with few or no comorbidities, others may be complicated and warrant a thorough diagnostic assessment. This is the reason why the patient's condition should be assessed by a neurologist. The goal is to get the most accurate diagnosis possible, so that the patient can receive the best possible treatment.

During the early stages of stroke, a doctor may prescribe clot-busting drugs to dissolve the blood clots in the arteries and restore blood flow to the brain area affected by the embolic event. These drugs are only effective if they are administered within the first few hours after a stroke occurs. These drugs are administered intravenously by emergency medical personnel in a hospital's emergency room. Blood-thinning medications may also be prescribed to patients, including aspirin, warfarin, and clopidogrel.

In both cases, the patient should seek medical attention immediately if any of these symptoms occur. Because embolic strokes are a major medical emergency and can result in death, it is essential to seek medical attention as soon as possible. By knowing the causes of stroke, a person can reduce their risk for an embolic stroke. The best way to prevent an embolic stroke is to follow a comprehensive health care plan. There is no such thing as too much research.

Among the various types of cardiac diseases that increase the risk of embolic stroke, atrial fibrillation is the most common risk factor. The risk for embolic stroke increases with age and is associated with a variety of cardiovascular diseases, including hypertension and diabetes. Furthermore, patients with atrial fibrillation have a higher risk for developing embolic stroke. And aortic stenosis and patent foramen ovale are also risk factors for embolic stroke.

However, there is hope for a prevention strategy based on scientific research. The embolic stroke of unknown source (ESUS) has a higher mortality rate than a traditional stroke. This type of stroke has many similar symptoms to regular stroke, including loss of coordination and speech. It may also affect a person's vision, writing, and swallowing. A person should seek medical care as soon as possible for embolic stroke.

Almost all vital processes in the human body are controlled by parts of the brain. Because these areas are involved in almost every aspect of life, the recovery process may take months or years. For this reason, specialists focus on prevention and minimizing negative effects of stroke. This preventive care includes a multidisciplinary approach. Physical therapy and passive gymnastics massage are effective in restoring basic functions. They can also prescribe medication to minimize the risk of stroke.

However, the embolic source of the stroke remains uncertain for a large number of ESUS patients. In many cases, the search for the source may be in vain. A number of widely used diagnostic tests are still insufficient to confirm the exact cause of embolic stroke in a patient. A comprehensive antithrombotic approach for ESUS should focus on identifying the embolic source. This is important in addressing the cause of the stroke.
