stroke
A stroke, previously known medically as a cerebrovascular accident (CVA), is the rapid loss of brain function(s) due to disturbance in the blood supply to the brain. This can be due to ischemia (lack of blood flow) caused by blockage (thrombosis, arterial embolism), or a hemorrhage (leakage of blood). As a result, the affected area of the brain cannot function, which might result in an inability to move one or more limbs on one side of the body, inability to understand or formulate speech, or an inability to see one side of the visual field. A stroke is a medical emergency and can cause permanent neurological damage, complications, and death. It is the leading cause of adult disability in the United States and Europe and the second leading cause of death worldwide. Risk factors for stroke include old age, hypertension (high blood pressure), previous stroke or transient ischemic attack (TIA), diabetes, high cholesterol, cigarette smoking and atrial fibrillation. High blood pressure is the most important modifiable risk factor of stroke. A silent stroke is a stroke that does not have any outward symptoms, and the patients are typically unaware they have suffered a stroke. Despite not
cardiac arrest
Cardiac arrest, (also known as cardiopulmonary arrest or circulatory arrest) is the cessation of normal circulation of the blood due to failure of the heart to contract effectively. Medical personnel can refer to an unexpected cardiac arrest as a sudden cardiac arrest or SCA. A cardiac arrest is different from (but may be caused by) a heart attack, where blood flow to the muscle of the heart is impaired. Arrested blood circulation prevents delivery of oxygen to the body. Lack of oxygen to the brain causes loss of consciousness, which then results in abnormal or absent breathing. Brain injury is likely if cardiac arrest goes untreated for more than five minutes. For the best chance of survival and neurological recovery, immediate and decisive treatment is imperative. Cardiac arrest is a medical emergency that, in certain situations, is potentially reversible if treated early. When unexpected cardiac arrest leads to death this is called sudden cardiac death (SCD). The treatment for cardiac arrest is cardiopulmonary resuscitation (CPR) to provide circulatory support, followed by defibrillation if a shockable rhythm is present. If a shockable rhythm is not present after CPR and other
Isaac Hayes
Isaac Lee Hayes, Jr. (August 20, 1942 – August 10, 2008) was an American songwriter, musician, singer, and actor. Hayes was one of the creative influences behind the southern soul music label Stax Records, where he served both as an in-house songwriter and as a record producer, teaming with his partner David Porter during the mid-1960s. Hayes, Porter, Bill Withers, the Sherman Brothers, Steve Cropper, and John Fogerty were inducted into the Songwriters Hall of Fame in 2005 in recognition of writing scores of notable songs for themselves, the duo "Sam & Dave", Carla Thomas, and others. The hit song "Soul Man", written by Hayes and Porter and first performed by "Sam & Dave", has been recognized as one of the most influential songs of the past 50 years by the Grammy Hall of Fame. It was also honored by The Rock and Roll Hall of Fame, by Rolling Stone magazine, and by the RIAA as one of the Songs of the Century. During the late 1960s, Isaac Hayes also began recording music and he had several successful soul albums such as Hot Buttered Soul (1969) and Black Moses (1971). In addition to his work in popular music, he worked as a composer of musical scores for motion pictures. He is well
