The heart, the pump that provides blood circulation in the body, is a muscular organ, hollow, consisting of four cavities, two upper (atria) and two lower (ventricles). Each atrium communicates with the ventricle on the same side through a hole provided with valves which have the function of vents, valves allow blood to flow one way, namely from the atria into the ventricles. The orifice from the right has three valves and one of the only two left. Some inflammatory heart diseases, most commonly rheumatism, may result in damage to these valves: affliction hole, stenosis, thus hampering blood flow from atrium into ventricle or preventing the tightness in the moment of the valves close in, insufficiency, which results in returning blood backwards, from the ventricle to atrium, sometimes both types of lesions may be associated.



The heart develops an enormous work, and for this its muscular walls must be well supplied with oxygenated blood. To this end, immediately after leaving the aorta artery from the left ventricle, two branches are split that surround the  surface of the heart like a crown (actually they were called coronary arteries) and then dividing into branches increasingly finer, forming a rich network of capillary vessels around the heart muscle fibers. Damaging the  coronary arteries ruins the feeding the heart muscle, as  it happens in heart diseases known as angina, myocardial infarction, chronic coronary.

Any anatomical or functional elements may have different factors of disease aggression, that’s why the heart diseases are very different between them.
In the category of sick people named cardiovascular patients, between all those who have signs of illness from heart and blood vessels and persons who are discovering a problem or an injury to the heart or vessels, without suffering too much that they sometimes have no obvious pain.



The symptoms of heart disease are different not only in relation to the structural element that suffered the greatest extent (myocardial, pericardium, valves, coronary arteries, etc..), but also in relation to the stage in which the disease is, there are differences high between early stage and advanced. This is because the heart does not use full force in all circumstances available, it has an important reserve that is utilized only in special circumstances, like physical effort. So, heart’s function is sometimes provided as if the body would be healthy.



These patients of heart disease are known under the name of compensated or latent. If  the disease produced changes exceed certain limits, heart function is disturbed and certain symptoms begin to appear that may highlight the sickness. As you can see,there are many difference between heart disease symptoms. The symptoms are different from person to person, but also the heart disease signs get different while the disease is evolving.
