Immune system plays an essential role in the heart.

The embryonic macrophages in the heart promote healing after injury, A new research has revealed that immune system plays an essential role in the heart's response to injury. Now, researchers says that two major pools of immune cells are at work in the heart. Both belong to a class of cells known as macrophages. One appears to promote healing, while the other likely drives ignition which is detrimental to long-term heart function.

Macrophages have long been thought of as a single type of cell, the author said. Our study shows really many different types of macrophages that originate in different places in the body. Some are protecting and can help blood vessels grow and reborn tissue. Others are unhealthy and can bring to harm.

Actually, the heart is one of the few organs with a association of macrophages formed in the embryo and maintained into adults. The heart, brain and liver are the only organs that contain large numbers of macrophages that arise in the yolk sac, in very early stages of arises, and they think these macrophages tend to be protective. Healthy hearts maintain this population of embryonic macrophages, as well as a smaller pool of adult macrophages derived from the blood. But during cardiac stress such as high BP, not only were more adult macrophages recruited from the blood and brought to the heart, they actually replaced the embryonic macrophages.

The study is published in the journal Immunity. (ANI)

Identification of Heart Stroke

STROKE: Remember The 1st Three Letters... S.T..R ...

My friend sent this to me and encouraged me to post it and spread the word. I agree. If everyone can remember something this simple, we could save some folks. 

STROKE IDENTIFICATION:
During a party, a friend stumbled and took a little fall - she assured everyone that she was fine and just tripped over a brick because of her new shoes. (they offered to call ambulance)

They got her cleaned up and got her a new plate of food - while she appeared a bit shaken up, Ingrid went about enjoying herself the rest of the evening. Ingrid's husband called later telling everyone that his wife had been taken to the hospital - (at 6:00pm , Ingrid passed away.)
She had suffered a stroke at the party . Had they known how to identify the signs of a stroke, perhaps Ingrid would be with us today.

Some don't die. They end up in a helpless, hopeless condition instead. It only takes a minute to read this...

STROKE IDENTIFICATION:

A neurologist says that if he can get to a stroke victim within 3 hours he can totally reverse the effects of a stroke...totally. He said the trick was getting a stroke recognized, diagnosed, and then getting the patient medically cared for within 3 hours, which is tough.

RECOGNIZING A STROKE

Remember the '3' steps, STR . Read and Learn!
Sometimes symptoms of a stroke are difficult to identify. Unfortunately, the lack of awareness spells disaster.
The stroke victim may suffer severe brain damage when people nearby fail to recognize the symptoms of a stroke.
Now doctors say a bystander can recognize a stroke by asking three simple questions :

S * Ask the individual to SMILE ..
T * = TALK. Ask the person to SPEAK A SIMPLE SENTENCE (Coherently) (eg 'It is sunny out today').
R * Ask him or her to RAISE BOTH ARMS .

If he or she has trouble with ANY ONE of these tasks, call the ambulance and describe the symptoms to the dispatcher.

NOTE : Another 'sign' of a stroke is
1. Ask the person to 'stick' out their tongue.
2. If the tongue is 'crooked', if it goes to one side or the other that is also an indication of a stroke.

A prominent cardiologist says if everyone who gets this e-mail sends it to 10 people; you can bet that at least one life will be saved.a

Painkillers linked to irregualr heart rhythm

    Commonly used painkillers like ibuprofen and aspirin can increase the risk of developing an irregular heart rhythm by up to 40 per cent, according to a new study published in the British Medical Journal. The anti-inflammatories have been previously linked to a higher chance of heart attacks and strokes. Now, researchers at Aarhus university Hospital in Denmark have shown for the first time a connection between the drugs and atrial fibrillation, also known as irregular heart rhythm or flutter. The condition is more common than heart failure and stroke, and is linked to a higher long-term risk of developing both, say the researchers. confirming the results, professor Henrik Toft Sorensen, Who led the study, however, said that heart disease patients should not stop taking the drugs, but they should discuss the potential risks with their doctor. "The absolute risk is till low. It increases your risk from a very low level to a higher -but still low-level." he was quoted by The daily Telegraph as saying. For their study, the researchers examined the records of 32,602 hospital patients with flutter between 1999 and 2009 and compared each to 10 randomly selected control patients.
