Know about Your Heart - (WORLD HEART DAY )

27.09.2013

Your heart is the size of your fist and the strongest muscle in your body.
Your heart started beating about three weeks after you were conceived. If you live to be 70 your heart will have beat two and a half billion times. Each heartbeat pumps blood around the body, pushing it from the left heart chambers, through arteries of ever-decreasing size, finally reaching the capillaries in all parts of the body.
Once your body has taken oxygen and nutrients from the blood, it is returned to the heart via the veins to the right chambers of the heart. On its way back, the blood passes through the liver and waste products are removed.
As marvelous as this system is, it is very vulnerable to damage from the things we do to it, like smoking, eating an unhealthy diet or putting it under stress. Or you may be born with a heart condition. When your heart’s functions become compromised, this is known as cardiovascular disease, a broad term that covers any disorder to the system that has the heart at its centre.

Heart Attack Warning Signs
Some heart attacks are sudden and intense — the "movie heart attack," where no one doubts what's happening. But most heart attacks start slowly, with mild pain or discomfort. Often people affected aren't sure what's wrong and wait too long before getting help. Here are signs that can mean a heart attack is happening:
Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain.
Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach.
Shortness of breath with or without chest discomfort.
Other signs may include breaking out in a cold sweat, nausea or lightheadedness.

As with men, women's most common heart attack symptom is chest pain or discomfort. But women are somewhat more likely than men to experience some of the other common symptoms, particularly shortness of breath, nausea/vomiting, and back or jaw pain.
