Transcript of Hard Heart

What is our problem?
A great problem many hospital patients encounter are heart problems. When the problem can't be fixed/solved easily, it's an artificial heart that needs to replace the real thing.
There are 2 types of artificial hearts; the first having sub-categories.

1. Ventricular Assist Device
Left Ventricular Assist Device
Right Ventricular Assist Device
Bi-ventricular Assist Device
Artificial hearts are lifesavers when there is no chance of a heart transplant.
A True Breakthrough In Medicine
Why an artificial heart?
Now for this implantation of a man-made heart to take place, it's not like the patient won't be living for a few hours and then will regain signs of life after the operation is over. What will happen is they will be hooked up to a heart-lung machine which continues the flow of blood circulating throughout the body and from/to the lungs.
Types of Artificial Hearts.
2. Total Artificial Heart (it works just like a a normal natural heart but uses a different 'impulse' source. For example: this new technology is called the AbioCor.
After the implantation, the patient must be careful of infection from the breaks in the skin so patients must take pills to prevent anything bad from happening.
But there is more............
The artificial heart is not made for those younger than 17 and is only recommended for those with serious heart conditions.

These hearts work just like the real thing, with valves that only let the blood travel in one direction (as do all valves).
A coil which is implanted within the body, away from the artificial heart, feeds the power provided by the external battery pack. Also, the rate of pump is automatic, sensing when the patient is active and when they are less active, and can slow or quicken its pace all on its own.
The AbioCor weighs much more than the heart you were born with, grew up with and live with. It weighs about 1361 grams while our real hearts weigh a mere 300 grams on average.

S.T.E.V.E. by Abiomed
Remember -- everyone has a heart whether it be real or artificial; whether it be in a literal sense or metaphorical sense.
Take S.T.E.V.E. for example, he had the heart and strength to help complete this presentation. Thank you S.T.E.V.E. :D
1. http://en.wikipedia.org/wiki/Heart#The_fully_divided_heart
- provided much information on function of the heart

2. http://kidshealth.org/kid/htbw/heart.html
- gives basic/general information on the heart

- information on the pulse that makes the beat and also introduces the other heart parts

4. http://en.wikipedia.org/wiki/Pump
- informed me of the lobe pump, which to me, roughly resembled the heart

5. http://en.wikipedia.org/wiki/Lobe_pump
- lobe pump function a liquid flow given

6. http://my.clevelandclinic.org/heart/heart-blood-vessels/what-does-heart-look-like.aspx
- has good diagrams of the heart, one showing the inside and another showing the outer parts
- explanations included

9. http://www.essortment.com/artificial-hearts-work-27353.html
- quite general

- great info on the types of artificial hearts and health conditions concerning it

11. http://heartdisease.about.com/cs/heartfailure/a/abiocor.htm

Taking the external battery into account which weighs about 1814 grams, you can understand how much of a hassle it can be to have an artificial heart. This is why it is important to keep your heart healthy.
The new AbioCor -- being the first independent artificial heart (meaning there is no machine that the heart must be hooked up to to work) -- is powered by a small portable battery on the exterior of the patient which lasts for a few hours.
It must be charged for a long time before it can be taken places along with the patient. This artificial heart can last for multiple years until a new one is needed.
Donations would be much appreciated by those in need of the help you are willing to provide. That is when you get to the age when you decide whether your heart should go towards helping another or stay with you.
A simple cash donation to a hospital can give a patient the hope and the will to carry on with their transplantation having the support of family, friends and strangers. Transplants are can be very nerve racking for the patient for their insides are being tampered with. If you could make a donation, as much as you have to offer, researchers would also get the money they need to advance modern medical studies and make something new and even more efficient than the current artificial hearts.
In Canada, a life is lost to heart disease or stroke every few minutes :(
Some diseases the heart may face during a lifetime
Coronary Heart Disease > The shrinking or clogging of the arteries
High Blood Pressure (HBP) or Hypertension > More pressure is needed to move blood through the arteries
Rheumatic Heart Disease > The malfunctioning of heart valves (blood spills into parts it wasn't set to be)
Pulmonary Heart Disease > A surplus or lack of blood circulating to the lungs
Tachycardia > The extremely fast pumping of the heart
Arrhythmia > Irregular beating of the heart
Ischemic Heart Disease > Blood Pressure is too low so exercise is needed to increase flow
Indeed things can be done to prevent heart disease...
For example, exercise always does one good. Choosing from a large variety of activities like sports or aerobic exercises are great ways to strengthen your heart. A balanced diet is the best diet there is. Starving is absolutely unrecommended. Once the body goes into starvation mode, it takes longer to burn calories meaning you lost weight at a slower rate than usual if you were to return to your original regimen. So eat well and remember, "It's in you to give" - Canadian Blood Service
