Tissue plasminogen activator (TPA)
There is opportunity to use alteplase (TPA) as a clot-buster drug to dissolve the blood clot that is causing the stroke. There is a narrow window of opportunity to use this drug. The earlier that it is given, the better the result and the less potential for the complication of bleeding into the brain.
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. Read more…
A stroke is a medical emergency. Anyone suspected of having a stroke should be taken to a medical facility immediately for evaluation and treatment. Initially, the doctor takes a medical history from the patient if he/she is alert or others familiar with the patient if they are available, and performs a physical examination. If a person has been seeing a particular doctor, it would be ideal for that doctor to participate in the assessment. Previous knowledge of the patient can improve the accuracy of the evaluation. A neurologist, a doctor specializing in disorders of the nervous system and diseases of the brain, will often assist in the diagnosis and management of stroke patients. Read more…
A stroke, or cerebrovascular accident (CVA), occurs when blood supply to part of the brain is disrupted, causing brain cells to die. When blood flow to the brain is impaired, oxygen and glucose cannot be delivered to the brain. Blood flow can be compromised by a variety of mechanisms.
Blockage of an artery
• Narrowing of the small arteries within the brain can cause a so-called lacunar stroke, (lacune=empty space). Blockage of a single arteriole can affect a tiny area of brain causing that tissue to die (infarct). Read more…
You can find out if you have high blood pressure by having your blood pressure checked regularly. Most doctors will diagnose a person with high blood pressure on the basis of two or more readings, taken on several occasions. A consistent blood pressure reading of 140/90 mm Hg or higher is considered high blood pressure, another term for hypertension.
Some people experience high blood pressure only when they visit the doctor’s office. This condition is called “white-coat hypertension.” If your doctor suspects this, you may be asked to monitor your blood pressure at home or asked to wear a device called an ambulatory blood pressure monitor. This device is usually worn for 24 hours and can take blood pressure every 30 minutes. Read more…
Diabetes is a serious disease. It happens when your blood levels of glucose, a form of sugar, are too high. Diabetes can lead to dangerous health problems. The good news is that high glucose levels can be managed to help control the disease and prevent or delay future problems.
Our bodies change the foods we eat into glucose. Glucose travels through the bloodstream to “fuel” or feed our cells. Insulin is a hormone that helps our bodies use glucose for energy. People with diabetes either do not make insulin, do not use insulin properly, or both. This means they have too much glucose (sugar) in their blood. As a result, they often feel tired, hungry, or thirsty; they may lose weight, urinate often, or have trouble with their eyes. In time, the high levels of this form of sugar in the blood (glucose) can hurt their eyes, kidneys, and nerves. It can also cause heart disease, strokes and even the need to remove all or part of a limb (amputation). Read more…
