QUOTE FOR WEDNESDAY:

“Emergency treatment for stroke depends on whether you’re having an ischemic stroke or a stroke that involves bleeding into the brain (hemorrhagic).  The impact of your stroke depends on the area of the brain involved and the amount of tissue damaged.”

MAYO CLINIC

Part III Stoke Awareness – Treatment and How to prevent a stroke!

TREATMENT OF STROKES

If you’re having a stroke, it’s critical that you get medical attention right away. Immediate treatment may minimize the long-term effects of a stroke and prevent death!

Ischemic Stroke Treatment

tPA, the Gold Standard

The only FDA approved treatment for ischemic strokes is tissue plasminogen activator (tPA, also known as IV rtPA, given through an IV in the arm). tPA works by dissolving the clot and improving blood flow to the part of the brain being deprived of blood flow. If administered within 3 hours(and up to 4.5 hours in certain eligible patients), tPA may improve the chances of recovering from a stroke. A significant number of stroke victims don’t get to the hospital in time for tPA treatment; this is why it’s so important to identify a stroke immediately.

Endovascular Procedures
Another treatment option is an endovascular procedure* called mechanical thrombectomy, strongly recommended, in which  trained doctors try  removing a large blood clot by  sending a wired-caged device called a stent retriever, to the site of the blocked blood vessel in the brain. To remove the brain clot, doctors thread a catheter through an artery in the groin up to the blocked artery in the brain. The stent opens and grabs the clot, allowing doctors to remove the stent with the trapped clot. Special suction tubes may also be used. The procedure should be done within six hours of acute stroke symptoms, and only after a patient receives tPA.

*Note: Patients must meet certain criteria to be eligible for this procedure.

Hemorrhagic Stroke Treatment

Endovascular Procedures
Endovascular procedures may be used to treat certain hemorrhagic strokes similar to the way the procedure is used for treating an ischemic stroke. These procedures are less invasive than surgical treatments, and involve the use of a catheter introduced through a major artery in the leg or arm, then guided to the aneurysm or AVM; it then deposits a mechanical agent, such as a coil, to prevent rupture.

Surgical Treatment
For strokes caused by a bleed within the brain (hemorrhagic stroke), or by an abnormal tangle of blood vessels (AVM), surgical treatment may be done to stop the bleeding. If the bleed is caused by a ruptured aneurysm (swelling of the vessel that breaks), a metal clip may be placed surgically at the base of the aneurysm to secure it.

How to prevent a stroke!

Treatment is also aimed at other factors that put you at risk, including high blood pressure, diabetes, and high cholesterol. But it takes more than just your doctor’s efforts. You also have an important role to play in preventing stroke. It’s up to you to make lifestyle changes that can lower your risk.

What you can do to prevent a stroke is this:

1-Control your blood pressure.

2-Lose Weight to the point that your in a healthy weight for your height.   If you’re overweight, losing as little as 10 pounds can have a real impact on your stroke risk.              Try to eat no more than 1,500 to 2,000 calories a day (depending on your activity level and your current body mass index).  Increase the amount of exercise you do with such activities as walking, golfing, or playing tennis, and by making activity part of every single day.

3-Exercise More-Exercise contributes to losing weight and lowering blood pressure, but it also stands on its own as an independent stroke reducer. Exercise at a moderate intensity 5x/wk and if you can’t do ½ hr as day spread it out into 2 15minute exercise moments for the day.

4- Drink-in moderation What you’ve heard is true. Drinking can make you less likely to have a stroke—up to a point. “Studies show that if you have about one drink per day, your risk may be lower.  I am not saying drink one glass of liquor a day but if you have to limit it to one glass a day.  Red wine your first choice, because it contains resveratrol, which is thought to protect the heart and brain.

5-Atrial Fibrillation-Atrial fibrillation is a form of irregular heartbeat that causes clots to form in the heart. Those clots can then travel to the brain, producing a stroke. “Atrial fibrillation carries almost a fivefold risk of stroke, and should be taken seriously; take your anticoagulant medication the MD orders to keep the blood thin to prevent clotting.

6-Treat diabetes –Having high blood sugar over time damages blood vessels, making clots more likely to form inside them putting the person at higher risk for a stroke.  So simply keep your sugar under control.

7-QUIT Smoking-Along with a healthy diet and regular exercise, smoking cessation is one of the most powerful lifestyle changes that will help you reduce your stroke risk

 

QUOTE FOR TUESDAY:

“When a person shows signs of having a stroke, time is the most critical factor for ensuring their survival and minimizing the extent of brain damage. Therefore, the speed at which a radiologist can determine which type of stroke has occurred is essential for administering the proper treatment. With speed and time as significant factors for saving a patient’s life, the standard test to assess a stroke has usually been computed tomography (CT) scans. CT scans vary in length, but they are generally very quick, and some may be completed within five minutes. ”

“The symptoms of stroke vary widely, depending on what part of the brain is affected, and whether the stroke is ischemic or hemorrhagic.”

QUOTE FOR MONDAY:

“Stroke is the fifth leading cause of death in the United States and is a major cause of serious disability for adults. About 795,000 people in the United States have a stroke each year.”

Centers for Disease Control and Prevention

QUOTE FOR THE WEEKEND:

“Arthritis is very common but is not well understood. Actually, “arthritis” is not a single disease; it is an informal way of referring to joint pain or joint disease. There are more than 100 types of arthritis and related conditions. People of all ages, sexes and races can and do have arthritis, and it is the leading cause of disability in America. More than 50 million adults and 300,000 children have some type of arthritis. It is most common among women and occurs more frequently as people get older.”

QUOTE FOR FRIDAY:

A Transient Ischemic Attack (TIA) is often called a mini-stroke, but it’s really a major warning.”

 
American Stroke Association (stroke.org)

What is a TIA=Transient Ischemic Attack?

 

Causes of a TIA:

1-Hemmoragic-a blood vessel that bursts in the brain causing lack of oxygen to be supplied to the area of the brain (a lobe) where the vessel ruptured.  Lack of oxygen to any area of the body tissue=starvation to the tissue; where in this case is the brain=a stroke.

2-Blockages-These blockages caused by the following: blood clots, athero-sclerosis, a common disorder, it happens due to fat, cholesterol, with even tar from smoking, or other substances that build up in the walls of the arteries forming hard structures called plaque and in time creating a blockage in the vessel interfering with blood supply providing oxygen to tissue and if blocked in the brain=high probability of a stroke occurring if not taken care of.   “Recommended related to Heart Disease” by Web MD which states that atherosclerosis is the key cause of heart attacks & strokes including it’s the number one killer in the United States.  Risk Factors for atherosclerosis include high blood pressure (b/p)=arteriosclerosis, blood level of high bad cholesterol (LDL), blood level of low good cholesterol (HDL), smoking, diabetes, and history of heart attacks in your nuclear family.  Definitely a healthy diet, having exercise in your life, and your weight within the therapeutic body mass index level will help prevent, if not treat, atherosclerosis.

The Risk Factors of a TIA, especially diet & sedentary lifestyle:

  1. High Blood Pressure (b/p)-This is also known as the diagnosis hypertension.  In understanding how hypertension works let’s use a metaphor:  Think of a blood vessel as a long thin balloon and if we stand on it the pressure will increase inside the balloon causing the diameter of the balloon to swell up.  If you continue to step on the balloon adding additional pressure this causes it to finally reach it’s total amount of pressure or when you exceed the total level of pressure this results in popping the balloon.  Similar concept with high b/p, that’s if the pressure keeps rising in our blood vessels due to blockage or vasoconstriction (which is making the vessels diameter more narrow=increased pressure in the vessels) sooner or later a vessel bursts somewhere in the body due to the b/p passing it’s total level in the amount of pressure that it can handle in the circulatory system which can result into a burst of an artery, like in the brain causing a stroke or in a vessel near the heart causing a myocardial infarction (but this is another topic some other day).  Think of food,  a human being not eating leads into starvation, well for blood cells lack of oxygen=starvation to the cells.  This causes in both situations or cases a lack of nutrition (the tissue is lacking oxygen).  With a stroke, not enough oxygen is getting to the brain resulting from either a hemorrhage (loosing too much blood=loosing to many cells=oxygen (food for tissue) or a blockage preventing 02 getting to the area.  Though many people have increased b/p due to only 2 things diet leading them to obesity, and lack of exercise due to a sedentary lifestyle, which could be changed and resolve the problem in most cases.  Increased b/p can also be due noncompliance- like continuing to smoke, or not following the healthy regimen the M.D. ordered for you as a patient.  The overall healthy regimen for a person with hypertension would be a low sodium diet (preventing further vasoconstriction), even low in cholesterol/fat/1800-2000 calories a day (preventing obesity or further weight gain), balancing rest with exercise and the b/p medications taken as prescribed, by their M.D.    So for many Americans hypertension can be controlled just by diet with balancing exercise with rest.  For others it might take a little more like doing which is what I just mentioned with following your medication regimen as ordered and going to your doctor having your b/p monitored, as your M.D. prescribes.
  2. Cholesterol is also found in some foods, such as seafood, eggs, meats and dairy products.LDL can cause plaque build-up. Plaque is a thick, hard substance that can clog arteries. Recent studies show that high levels of LDL and triglycerides (blood fats) raise the risk of ischemic stroke. Plaque can also increase risk of a transient ischemic attack (TIA) where stroke symptoms go away within 24 hours.      –The second main type of cholesterol is high-density lipoprotein (HDL), often called the “goodcholesterol. High levels of HDL may reduce stroke risk.                                                                      -Because cholesterol does not dissolve in the blood on its own, it must be carried to and from cells by particles called lipoproteins. There are two main types of lipoproteins: low-density lipoproteins (LDL)=the bad cholesterol and high-density lipoproteins=the good cholesterol (HDL).                                                                                                             -The National Stroke Association states the following about cholesterol: Cholesterol is a soft, waxy fat (lipid) that is made by the body. It is found in the bloodstream and in all of your body’s cells. The body needs cholesterol to form cell membranes, some hormones and vitamin D.
  3. Smoking-For starters, this unhealthy habit puts you at risk for high blood pressure since it causes vasoconstriction (narrowing) of the vessels in our body due to the nicotine.  The answer to this risk factor is simply quit this unhealthy habit. I have a dear friend doing great in quitting this habit now. Smoking adds to the plaque building up in the vessels.  Centers for Disease state that in 2010 the leading cause of death was heart disease followed by cancer than to chronic respiratory disease and lastly stroke.  Over time a healthy diet balanced with exercise daily or every 2 days for 30minutes would help decrease the cardiac disease and stroke.  The American Lung Association states that smoking is directly responsible for approximately 90 percent of lung cancer deaths and approximately 80-90 percent of COPD (emphysema and chronic bronchitis) deaths.    Know this:
    • Smoking harms nearly every organ in the body, and is a main cause of lung cancer and chronic obstructive pulmonary disease (COPD, including chronic bronchitis and emphysema). It is also a cause of coronary heart disease (CAD), stroke and a host of other cancers and diseases.  So think twice before becoming a smoker.
    • To understand smoking easy, over a long process, this occurs:  Let’s take a car for instance, if the transmission is bad and not repaired by a mechanic the engine will be affected and soon fail completely.  Now let’s take the lungs (this is the transmission of the body), if they are bad and you don’t go to a doctor to help treat the problem the heart will be affected at some point to failure in function. This is the same with a heart (the engine of the body), that when it is bad with no repair or Rx it will soon affect the lungs (the transmission of the body). When one of these organs works at its fullest potential without the other organ properly functioning, in time, it will affect the other organ.  If a smoker doesn’t quit it causes COPD=Emphysema (this does take over years) and it will affect the heart in time to not function as effectively with someone who has healthy lungs.  Worse, if you don’t quit smoking you increase the risk of getting CAD (coronary artery disease from tar, high cholesterol).       Add to the problem atherosclerosis if you already have the diagnosis CAD which is caused by fatty materials (lipids), fibrous tissue with tar (from the smoking) causing blockages in the vessels or even better cause arteriosclerosis (narrowing of the vessels). You also have a risk at lung cancer.  So smoke? No!

Stroke verses TIA=Nonreversible verses Reversible.

Stroke is scarring to the brain where TIA doesn’t.  TIA has reversible stroke symptoms that aren’t permanent and that is the reason its called a “mini-stroke”.

Like Heart Attack verses Angina, Heart Attack is scarring to the heart verses no scarring to the heart for Angina. Both Angina and TIA are just lack of oxygen to the organs the heart and the brain causing the symptoms due to lack of oxygen called ischemia.  Both heart attack and stroke are both a lot worse than just ischemia.  They both get to the point where there in no oxygen causing actual permanent damage to the organ since the problem never reversed=scarring to the heart and brain.  High cholesterol levels or plaque build-up in the arteries can block normal blood flow to the brain and cause a stroke or to the heart causing a MI. High cholesterol may also increase the risk of heart disease and atherosclerosis, which are both risk factors for stroke.

So without controlling your blood pressure therapeutically or without ending your smoking or without eating healthy with living no healthy habits puts you at risk for a TIA or Stroke.  The heart at first will be able to compensate with blockages starting in the brain or heart without symptoms but overtime living these unhealthy habits the heart or brain may find it so hard to function or work that the heart or brain starts to fail in doing its job effectively due to a vessel in the heart or brain that has a partial or completely blocked vessel causing that organ to have ischemia (reversible still) to attack (scarred=not reversible).

Let’s take the car, you do maintenance to the vehicle it will operate better and last longer, well the exact principle with the human body=treat it better is will last longer.  All this means=Good Diet, Good Exercise balanced with rest, no smoking with B/P well controlled. If with Bad Diet, Overweight, Smoking, Hypertension-High B/P, Bad Health Habits puts you at risk for a TIA or Stroke.  Pretty simple isn’t it.

PREVENTION MEASURES FOR A TIA OR STROKE:

So on average eat a healthy diet, keep your weight in a therapeutic range, properly exercising, not with high B/P, not smoking, not with high cholesterol than expect to be at highier odds you will be leaning towards living a longer life (not shortening your life span or not having a short life).  Just get a yearly physical and that always leaves your doctor in picking up problems much quicker and putting it to a stop or a reversing it to possibly becoming extinct in time (Ex. high b/p, high cholesterol, lowering weight if overweight).
