The National Institutes of Health (NIH) in United States identifies LDL cholesterol as the primary target of cholesterol-lowering therapy. However, the general method used to determine the value of LDL is calculated, which is based on the value of total cholesterol, HDL cholesterol and triglycerides, which are reported the accuracy only about 70%.

The main problem in the calculation are triglycerides. If the value is very high triglycerides, for example, because patients are not fasting, then the resulting value will be low LDL false. And if the patient trigliserda above 400 mg / dl, the calculation can not be used at all. If the calculations used to value high triglycerides, the LDL was not detected, so do not get fat reduction therapy.

NCEP standardization criteria for cholesterol tests:
To increase the standardized testing of cholesterol, NCEP has issued guidelines for the measurement of HDL and LDL cholesterol.

NCEP LDL cholesterol Director recommends examination as the main target for the evaluation and monitoring of coronary heart disease risk. Lipoprotein has long been known as an essential element for the occurrence of atherosclerosis. Lipoprotein is heterogeneous, consisting of multiple subclasses that vary in particle size, density and chemical composition.

The National Cholesterol Education Program (NCEP) has emphasized the important role of lipoproteins in adult treatment panel guidelines. In the 2001 edition, the guidelines specifically emphasize on cholesterol levels as a benchmark for intervention, with or without treatment.

It is known that in certain circumstances, such as metabolic syndrome, increased triglycerides, low HDL and smaller population and dense.

This led to the American Association of Clinical Endocrinologists (AACE) paying attention to the fact that small particles of LDL seems very atherogenik denses and generally lead to Coronary Heart Disease (CHD). Patients may carry these particles despite normal LDL values.

More recently, Intermediate-density lipoprotein (IDL) which has been able in identification with the new system of LDL sub-fraction was also known to be involved in atherosclerotic process. Get the best price with Overstock Deals.

Present American Heart Association guidelines recommend that if used, TPA must be given within three hours after the onset of symptoms. Normally, TPA is injected into a vein in he arm. The time frame for use can be extended to six hours if it is dripped directly into the blood vessel that is blocked. This is usually performed by an interventional radiologist, and not all hospitals have access to this technology.

For posterior circulation strokes that involve the vertebrobasilar system, the time frame for treatment with TPA may be extended even further to 18 hours.

Heparin and aspirin
Drugs to thin the blood (anticoagulation; for example, heparin) are also sometimes used in treating stroke patients in the hopes of improving the patient’s recovery. It is unclear, however, whether the use of anticoagulation improves the outcome from the current stroke or simply helps to prevent subsequent strokes (see below). In certain patients, aspirin given after the onset of a stroke does have a small, but measurable effect on recovery. The treating doctor will determine the medications to be used based upon a patient’s specific needs.

Managing other Medical Problems
Blood pressure and cholesterol control are key to prevention of future stroke events. In transient ischemic attacks, the patient may be discharged with medications even if the blood pressure and cholesterol levels are acceptable. In an acute stroke, blood pressure will be tightly controlled to prevent further damage.

In patients with diabetes, the blood sugar (glucose) level is often elevated after a stroke. Controlling the glucose level in these patients may minimize the size of a stroke. Finally, oxygen may administered to stroke patients when necessary.

Rehabilitation
When a patient is no longer acutely ill after a stroke, the healthcare staff focuses on maximizing the patient’s functional abilities. This is most often done in an inpatient rehabilitation hospital or in a special area of a general hospital. Rehabilitation can also take place at a nursing facility.

The rehabilitation process can include some or all of the following:
1. speech therapy to relearn talking and swallowing;
2. occupational therapy to regain dexterity in the arms and hands;

3. physical therapy to improve strength and walking; and
4. family education to orient them in caring for their loved one at home and the challenges they will face.

The goal is for the patient to resume as many, if not all, of their pre-stroke activities and functions. Since a stroke involves the permanent loss of brain cells, a total return to the patient’s pre-stroke status is unfortunately, not a realistic goal in many cases.

When a stroke patient is ready to go home, a nurse may come to the home for a period of time until the family is familiar with caring for the patient and the procedures for giving various medications. Physical therapy may continue at home. Eventually, the patient is usually left at home with one or more caregivers, who now find their lives have changed in major ways. Caring for the stroke patient at home may be easy or very nearly impossible. At times, it becomes apparent that the patient must be placed in a board and care home or a skilled nursing facility because adequate care cannot be given at home despite the good intentions of the family.

What complications can occur after a stroke?
A stroke can become worse despite an early arrival at the hospital and appropriate medical treatment. It is not unusual for a stroke and a heart attack to occur at the same time or in very close proximity to each other.

During the acute illness, swallowing may be affected. The weakness that affects the arm, leg, and side of the face can also impact the muscles of swallowing. A stroke that causes slurred speech seems to predispose the patient to abnormal swallowing mechanics. Should food and saliva enter the trachea instead of the esophagus when eating or swallowing, pneumonia or a lung infection can occur. Abnormal swallowing can also occur independently of slurred speech.

Because a stroke often results in immobility, blood clots can develop in a leg vein (deep vein thrombosis). This poses a risk for a clot to travel upwards to and lodge in the lungs – a potentially life-threatening situation (pulmonary embolism). There are a number of ways in which the treating physician can help prevent these leg vein clots. Prolonged immobility can also lead to pressure sores (a breakdown of the skin, called decubitus ulcers), which can be prevented by frequent repositioning of the patient by the nurse or other caretakers.

Stroke patients often have some problem with depression as part of the recovery process, which needs to be recognized and treated.

The prognosis following a stroke is related to the severity of the stroke and how much of the brain has been damaged. Some patients return to a near-normal condition with minimal awkwardness or speech defects. Many stroke patients are left with permanent problems such as hemiplegia (weakness on one side of the body), aphasia (difficulty or the inability to speak), or incontinence of the bowel and/or bladder. A significant number of persons become unconscious and die following a major stroke.

If a stroke has been massive or devastating to a person’s ability to think or function, the family is left with some very difficult decisions. In these cases, it is sometimes advisable to limit further medical intervention. It is often appropriate for the doctor and the patient’s family to discuss and implement orders to not resuscitate the patient in the case of a cardiac arrest, since the quality of life for the patient would be so poor. In many cases, this decision is made somewhat easier if the patient has made such a request when well.

What can be done to prevent a stroke?
Risk factor reduction
High blood pressure: The possibility of suffering a stroke can be markedly decreased by controlling the risk factors. The most important risk factor for stroke is high blood pressure. When a person’s blood pressure is persistently too high, roughly greater than 130/85, the risk of a stroke increases in proportion to the degree by which the blood pressure is elevated. Controlling blood pressure in the normal range decreases the chances of a stroke.

Smoking: Another important risk factor is cigarette or other tobacco use. Cigarettes cause the carotid arteries to develop severe atherosclerosis, which can lead to their closure and block the blood flow to the brain. Atherosclerosis in general, including involvement of the arteries that supply blood to the heart, is accelerated by smoking. So, when an individual smokes, the main question becomes – which will occur first; a stroke, heart attack, or lung cancer?

Diabetes: Another risk factor for developing a stroke is diabetes mellitus. Diabetes causes the small vessels to close prematurely. When these blood vessels close in the brain, small (lacunar) strokes may occur. Good control of blood sugar is important in decreasing the risk of stroke in diabetic patients. An elevated level of blood cholesterol is also a risk factor for a stroke due to the eventual blockage of blood vessels (atherosclerosis). A healthy diet and medications can help normalize an elevated blood cholesterol level.

Blood thinner/warfarin: An irregular heart beat (atrial fibrillation in particular) is associated with an increased risk of an embolic stroke, in which the blood clot travels from the heart, through the bloodstream, and into the brain. Warfarin (Coumadin) is a blood “thinner” that prevents the blood from clotting. This medication is often used in patients with atrial fibrillation to decrease this risk. Warfarin is also sometimes used to prevent the recurrence of a stroke in other situations, such as with certain other heart conditions and conditions in which the blood has a tendency to clot on its own (hypercoagulable states). Patients taking warfarin need to have periodic blood checks to make sure that their current dose is producing the desired effect. Patients on warfarin also need to know that they are at increased risk for bleeding, either externally or internally.

Aspirin and other antiplatelet therapy: Many stroke patients who do not require warfarin can use another class of medicines called “antiplatelet” drugs to reduce their risk of suffering another stroke. These medicines reduce the tendency of the blood to clot (clog) in the arteries. As a side effect, patients on these medicines usually have a higher likelihood of bleeding, but this risk is less than when taking an anticoagulant like warfarin. The most commonly prescribed first-choice antiplatelet agent for preventing a stroke recurrence is aspirin. If the patient has an adverse reaction to aspirin or has a stroke despite being on aspirin, newer antiplatelet preparations can be used [clopidogrel (Plavix), dipyridamole (Persantine).

Carotid endarterectomy: In many cases, a person may suffer a TIA or a stroke that is caused by the narrowing or ulceration (sores) of the carotid arteries (the major arteries in the neck that supply blood to the brain). If left untreated, patients with these conditions have a high risk of experiencing a major stroke in the future. An operation that cleans out the carotid artery and restores normal blood flow is known as a carotid endarterectomy. This procedure has been shown to markedly reduce the incidence of a subsequent stroke. In patients who have a narrowed carotid artery, but no symptoms, this operation may be indicated in order to prevent the occurrence of a first stroke.

What is in the future for stroke treatment?
Currently, studies are being done on additional drugs that dissolve clots. These drugs are administered either in the veins (like TPA) or directly into the clogged artery. The goal of these studies is to determine which stroke patients might benefit from this new and aggressive form of treatment.

New medications are also being tested that help slow the degeneration of the nerve cells that are deprived of oxygen during a stroke. These drugs are referred to as “neuroprotective” agents, an example of which is sipatrigine. Another example is chlormethiazole, which works by modifying the expression of genes within the brain. (Genes produce proteins that determine an individual’s makeup.)

Finally, stem cells, which have the potential to develop into a variety of different organs, are being used to try to replace brain cells damaged by a previous stroke. In many academic medical centers, some of these experimental agents may be offered in the setting of a clinical trial. While new therapies for the treatment of patients after a stroke are on the horizon, they are not yet perfect and may not restore complete function to a stroke victim.

Just because a person has slurred speech or weakness on one side of the body does not necessarily signal the occurrence of a stroke. There are many other possibilities that can be responsible for these symptoms. Other conditions that can mimic a stroke include:
• brain tumors,
• a brain abscess (a collection of pus in the brain caused by bacteria or a fungus),
• migraine headache,
• bleeding in the brain either spontaneously or from trauma,
• meningitis or encephalitis,
• an overdose of certain medications, or
• an imbalance of sodium, calcium, or glucose in the body can also cause changes in the nervous system that can mimic a stroke.

In the acute stroke evaluation, many things will occur at the same time. As the physician is taking the history and performing the physical examination, nursing staff will begin monitoring the patient’s vital signs, getting blood tests, and performing an electrocardiogram (EKG or ECG).

Part of the physical examination that is becoming standardized is the use of a stroke scale. The American Heart Association has published a guide to the examination of the nervous system to help care providers determine the severity of a stroke and whether aggressive intervention may be warranted.

There is a narrow time frame to intervene in an acute stroke with medications to reverse the loss of blood supply to part of the brain (please see TPA below). The patient needs to be appropriately evaluated and stabilized before any clot-busting drugs can be potentially utilized.

Computerized tomography: In order to help determine the cause of a suspected stroke, a special x-ray test called a CT scan of the brain is often performed. A CT scan is used to look for bleeding or masses within the brain, a much different situation than stroke that is also treated differently.

MRI scan: Magnetic resonance imaging (MRI) uses magnetic waves rather than x-rays to image the brain. The MRI images are much more detailed than those from CT, but this is not a first line test in stroke. While a CT scan may be completed within a few minutes, an MRI may take more than an hour to complete. An MRI may be performed later in the course of patient care if finer details are required for further medical decision making. People with certain medical devices (for example, pacemakers) or other metals within their body, cannot be subjected to the powerful magnetic field of an MRI.

Other methods of MRI technology: An MRI scan can also be used to specifically view the blood vessels non-invasively (without using tubes or injections), a procedure called an MRA (magnetic resonance angiogram). Another MRI method called diffusion weighted imaging (DWI) is being offered in some medical centers. This technique can detect the area of abnormality minutes after the blood flow to a part of the brain has ceased, whereas a conventional MRI may not detect a stroke until up to six hours after it has started, and a CT scan sometimes cannot detect it until it is 12 to 24 hours old. Again, this is not a first line test in the evaluation of a stroke patient, when time is of the essence.

Computerized tomography with angiography: Using dye that is injected into a vein in the arm, images of the blood vessels in the brain can give information regarding aneurysms or arteriovenous malformations. As well, other abnormalities of brain blood flow may be evaluated. With increasingly sophisticated technology, CT angiography has supplanted conventional angiograms.

Conventional angiogram: An angiogram is another test that is sometimes used to view the blood vessels. A long catheter tube is inserted into an artery (usually in the groin area) and dye is injected while x-rays are simultaneously taken. While an angiogram delivers some of the most detailed images of the blood vessel anatomy, it is also an invasive procedure and is used only when absolutely necessary. For example, an angiogram is done after a hemorrhage when the precise source of bleeding needs to be identified. It also is sometimes performed to accurately evaluate the condition of a carotid artery when surgery to unblock that blood vessel is contemplated.

Carotid Doppler ultrasound: A carotid Doppler ultrasound is a non-invasive (without injections or placing tubes) method that uses sound waves to screen for narrowings and decreased blood flow in the carotid artery (the major artery in the neck that supplies blood to the brain).

Heart tests: Certain tests to evaluate heart function are often performed in stroke patients to search for the source of an embolism. An echocardiogram is a sound wave test that is done by placing a microphone device on the chest or down the esophagus (transesophageal echocardiogram) in order to view the heart chambers. A Holter monitor is similar to a regular electrocardiogram (EKG), but the electrode stickers remain on the chest for 24 hours or longer in order to identify a faulty heart rhythm.

Blood tests: Blood tests such as a sedimentation rate and C-reactive protein are done to look for signs of inflammation that can suggest inflamed arteries. Certain blood proteins that can increase the chance of stroke by thickening the blood are measured. These tests are performed to identify treatable causes of a stroke or to help prevent further injury. Screening blood tests looking for potential infection, anemia, kidney function, and electrolyte abnormalities may also be considered.
