Transcript of Stroke, Angina and Infarction

Angina, Stroke, Infarction What is a Stroke? Causes sudden loss of brain function.
It is caused by the interruption of flow of blood to the brain (ischemic stroke) or the rupture of blood vessels in the brain (hemorrhagic stroke). What is Angina? Is the chest pain, discomfort, or tightness that occurs when an area of the heart muscle is receiving decreased blood oxygen supply. or angina pectoris Is when the circulation to a region of the body is obstructed and results in necrosis (tissue death). Infarction Causes of a Stroke - A stroke is caused by interrupted blood flow to the brain or a rupture in the blood vessels that can cause bleeding or the brain cells to die. –The lack of oxygen rich blood to the heart is usually a result of narrower coronary arteries due to plaque buildup, a condition called atherosclerosis.
–Narrow arteries increase the risk of pain, coronary artery disease, heart attack, and death. Angina Infarction – Caused by an obstruction of the tissue's blood supply, which leads to a local lack of oxygen. Diagnosis and Symptoms The three conditions can be diagnosed using the symptoms that may possibly lead to the condition. Other than performing medical tests, such as blood tests, CT scans and MRI's as a diagnosis for stroke, angina and infarction, one may also use the symptoms to confirm the conditions. Symptoms of Stroke Symptoms of Angina Pain that starts in the centre of your chest, but spreads to your left arm, neck, back, throat or jaw.
Tightness, pressure, squeezing and/or aching feeling in your chest or arm(s).
Feeling of moderate to severe indigestion that is persistent.
Sharp, burning or cramping pain.
An ache starting in, or spreading to, your neck, jaw, throat, shoulder, back or arm(s).
Discomfort in your neck or upper back, particularly between the shoulder blades.
Numbness or a loss of feeling in your arms, shoulders or wrists. Symptoms of Infarction Pain, fullness, and/or squeezing sensation of the chest
Jaw pain, toothache, headache
Shortness of breath
Nausea, vomiting, and/or general epigastric (upper middle abdomen) discomfort
Sweating
Heartburn and/or indigestion
Arm pain (more commonly the left arm, but may be either arm)
Upper back pain
General malaise (vague feeling of illness) If these symptoms result in a condition and affect an individual's lifestyle...

The person should take caution of their clothing choices such as, avoid tight-fitting sleeves, arm holes, pant legs, waistlines and wear clothes that do not need to be put over the head.
Shoes need to be ideal for a stroke patient such as having , low heels, shock absorbing soles, Velcro fasteners, deep, rounded toe boxes, and leather or canvas uppers.
Other lifestyle changes like, installing bars in the bathtub, reducing physical sports and enjoying low stress activities such as playing cards.
Personal hygiene and skin care should be considered, as stroke disease may cause skin damage and cause infections. Treatments for a stroke The treatment you receive will depend on the type of stroke you have, how serious your stroke is, your age and general health, and how soon you arrive at the hospital. tPA is a drug that can stop a stroke caused by a blood clot by breaking up the clot.

Cost: More than $2000 per stroke person
Effectiveness: tPA can only be given to patients who are having a stroke produced by a blood clot.It must be dosed within three hours of the onset of symptoms. tPA cannot be used in every situation and other drugs are required. It also increases survival by 1.1%.
Equipment: tPA is intravenously injected into the bloodstream using an IV and be monitored in an ICU setting for 24 hours. tPA (tissue plasminogen activator) Surgery may be obligatory to repair damage after a stroke or to prevent a stroke from occurring.
Surgery may be performed to eliminate blood that has pooled in the brain after a hemorrhagic stroke, to restore broken blood vessels, or to take out plaque from inside the carotid artery.

Cost:Varies from $15 000 t0 $ 40 000
Effectiveness: Effective as the cause for the stroke will be physically treated; the rupture in the blood vessel will be taken out and the clot in the blood vessel will be removed.
Equipment: Surgery will be like any other surgery and use regular surgical equipment. Surgery Some people may do good to from treatments that are performed through a thin, flexible tube called a catheter into the blood vessels.
Many of these procedures are new and not all hospitals may be able to do them.

The procedure is expensive and the effectiveness of it is questioned as it may also bring side affects and/or may not be successful
Surgery will need equipment such as the catheter so it could inserted into the blood vessels. Non-surgical procedures Treatment for Angina Lifestyle adjustments and medications are the most general ways to take care of and control angina. Occasionally, surgery may be necessary to be done. Lifestyle changes:
It is recommended to stay physically active with the approval of your doctor. It is best to live in a more comfortable environment and with fewer angina attacks by controlling your risk factors such as blood pressure, diabetes and high blood cholesterol. It is best to be having a healthy diet, being smoke-free, limiting your alcohol use and decreasing stress.
Medications: Certain medications may help prevent or relieve the symptoms of angina.
Anti-platelets
Beta-blockers
Calcium channel blockers
Nitroglycerin Interesting Facts Did you know? Deaths
•Stroke is the third leading cause of death in Canada.
•Six percent of all deaths in Canada are due to stroke.
•Each year, nearly 14,000 Canadians die from stroke
There are over 50,000 strokes in Canada each year. That’s one stroke every 10 minutes. Of every 100 people who have a stroke
10 recover completely (10%)
25 recover with a minor impairment or disability (25%)
40 are left with a moderate to severe impairment (40%)
10 are so severely disabled they require long-term care (10%) Audience Question Time!!!
