If they have a sudden onset as it happens in acute myocardial infarction massive, rapid tachyarrhythmia or rupture occurs a valve endocarditis associated with a marked reduction in cardiac output. These phenomena are associated with symptoms caused by inadequate perfusion of the organs and bed acute venous congestion ventricle affected accordingly. If anatomic abnormalities are gradually devel or if the patient survives an acute attack become operational some compensatory mechanisms especially cardiac remodeling and neurohormonal activation which enables that body to tolerate anatomical anomaly and reduced cardiac
Shock Definition Shock is a medical emergency in which the organs and tissues of the body are not receiving an adequate flow of blood. This deprives the organs and tissues of oxygen (carried in the blood) and allows the buildup of waste products. Shock can result in serious damage or even death.
Note that this patient’s right eye has a severe CRVO – dilated veins and widespread retinal hemorrhages. Compared with the patient’s left retina (image on the right) in which there are no retinal hemorrhages Choice “A” is not the best answer. CRAO develops when an embolusi blocks the retinal artery. Most commonly carotid plaques are the source of the emboli.
What are the symptoms of heart failure? • Shortness of breath, especially when you lie • Feeling tired, exhaustion • cough or wheezing, especially when the person you exercise or lie • Swelling in the feet, ankles and legs • Weight gain due to retention • Confusion or lack of mental clarity What are the causes?
Another problem that can cause cerebral palsy is abnormal development of the brain. Anything that changes or affects the brains normal development and leads to the way the brain transmits information to the muscles. It can be affected by mutations in the genes that play a role in the brain’s development, an infection in the mother, or trauma/injury to the unborn child’s head. The third problem that can cause cerebral palsy is intracranial hemorrhage (bleeding in the brain) and stroke. Bleeding in the brain is very serious and dangerous because it can deprive the brain of blood, causing parts of the brain to die.
This can lead to heart and damage the heart muscle permanently crisis; • high blood pressure, which is also called hypertension; • disease of the heart valves - there may be a leak in the valves or those may stiffen, especially the sigmoid valves and mitral; • a disorder of cardiac muscle, which is also called cardiomyopathy. That may be caused by a virus, bacterium or other infections; • damage to the heart caused by the abuse of alcohol or drugs; • congenital heart disease and heart defects that exist at birth; • an irregular heartbeat, especially if there is rapid or chaotic. The heart does not pump enough blood when his rhythm is abnormal; • certain lung disorders, such as pulmonary hypertension, which occurs when the right ventricle dilates, causing heart failure on the right. Normal Heart congestive heart é START T How is the diagnosis?
Thoracic Aortic Aneurysm is an abnormal bulging or ballooning of the portion of the aorta the passes through the chest. The most common cause is atherosclerosis, or hardening of the arteries(AHA) Risk factors may include, aging, genetic conditions such as Marfan and Loeys-Dietz Syndrome, Inflammation of the aorta, injury from falls or other trauma, and or, Syphilis. A patient with Thoracic Aortic Aneurysm may not have or experience any symptoms until it begins to leak blood into the nearby tissue or expand. There are many symptoms such as hoarseness, swallowing problems, swelling in neck, chest or upper back pains, and many more to include.
There are several procedures available for people who are disabled by frequent vertigo attacks despite drug treatment. The procedures aim to either reduce fluid pressure in the inner ear or destroy inner ear balance function. The least destructive of these procedures is called endolymphatic sac decompression. Essentially, the bone overlaying the endolymphatic sac is exposed and a thin sheet of flexible plastic material is placed over the ear. People who have severe, frequent episodes despite these treatments may need a surgical procedure.
A subdural hematoma occurs when a blood clot forms underneath the skull and dura matter but outside of the brain. These can form from a tear in the veins that lead from the brain to the dura or from a cut on the brain itself. A contusion or intracerebral hematoma is a bruise on the brain itself. This type of ICH causes bleeding and swelling inside the brain around the area where the head was struck. a diffuse axonal injury (DAI) are fairly common and are usually caused by shaking of the brain back and forth, which can happen in motor vehicle accidents or from falls.
This damage can make the heart unable to properly handle sudden demands such as increased heart rate, blood pressure, infection or water retention (Mayo Clinic, 2014). When the heart is unable to handle these sudden demands, fluid backs up into the lungs and collects in the alveolar sacs. A third cause of cardiogenic pulmonary edema is heart valve
For this paper I researched strokes, more specifically, transient ischemic attacks or TIA’s. The difference between a transient ischemic attack and a stroke is that the blockage with a TIA is transient, or in other words temporary. A transient ischemic attack is what occurs when the blood flow to part of the brain is either blocked or reduced. This usually happens because of a blood clot. After some time the blood begins to flow normally again and the symptoms dissipate.
Takayasu Arteritis Takayasu arteritis is a rare condition that may also be called pulseless disease. Takayasu arteritis is caused by inflammation in your large blood vessels (vasculitis). It mainly affects your aorta, which is a large blood vessel that carries blood away from the heart, and the large blood vessels that branch off from it. Areas of the aorta or other affected blood vessels can become narrowed, blocked, or weakened because of the inflammation.
Pneumocephalus may not cause symptoms and the body may absorb the air over time. However, if intracranial air builds up and cannot be released or absorbed, it can put pressure on your brain (tension pneumocephalus). Tension pneumocephalus is a medical emergency that requires immediate treatment. CAUSES Neurosurgery is a common cause of pneumocephalus.
