Heart Atack

million Americans suffer a heart attack every year, and almost half a million die, according to the American Heart Association. A heart attack often is the first symptom of coronary artery disease. The blockage usually is caused by atherosclerosis, the build-up of plaque in the artery walls, and/or by a blood clot in a coronary artery. A slow buildup of this plaque may almost block one of your coronary arteries. The cause of the heart is not always known. Heart attacks may occur when you are...

The Human Heart

The Human Heart The Human Heart is one of the most important organs in the entire human body. The heart is a muscular organ that acts like a pump to continuously send blood through the body. The heart beats approximately about seventy-two times per minute of our lives. Without the heart’s pumping action, blood can’t circulate within the human body. The heart is enclosed in a double walled sac called the Pericardium. The pericardium has outer and inner coats. The outer coat is tough and thickened...

Heart Failure

 The term “heart failure” sounds as if the heart has already failed. This can increase a person’s anxiety especially in the aging population that is a targeted community for this disease assuming that the failure is equivalent to death. Heart failure is actually the decline in the hearts ability to sufficiently pump oxygenated blood to the rest of the body. Many people can live with heart failure and are able to manage it through lifestyle changes, prescribed medication compliance, and regular...

The human heart is slightly bigger than the size of ones fist. It is situated at a very safe place which is between the cage bones, i.e., in the center of the chest. Usually it is slightly on the left side of the chest but in rare cases, it can be found on the right side. Heart is responsible for the blood flow to every single part of the body by constant contraction and relaxation of cardiac muscles. This is the reason why we hear rhythmic beats all the time.
