Congestive Heart Failure

Introduction

The heart is the body 's main circulatory system . It is a muscular organ located in the conical chest cavity . It works like a pump, pushing blood through the body. Its size is slightly larger than the fist of the wearer. The heart is an organ muscular self-controlled, a pump applicant and stimulating, consisting of two parallel pumps that work in unison to propel blood to all organs of the body. The atria are chambers of receipt, which send blood to get into the ventricles, chambers that function as expulsion. The right heart receives poorly oxygenated blood from:

The inferior vena cava (IVC), which carries blood from the chest , the abdomen and lower extremities

The superior vena cava (SVC), which receives blood from the upper limbs and head.

The inferior vena cava and the superior vena cava blood pour some peroxide in the right atrium. It gets inside the right ventricle through the tricuspid valve , and from here is driven into the lungs through the pulmonary arteries, right ventricle separated from the pulmonary valve .

Once oxygenated as it passes through the lungs, blood returns to the left heart through the pulmonary veins entering the left atrium. From there it goes to the left ventricle, separated from the left atrium for mitral valve . From the left ventricle, blood is propelled into the aorta through the aortic valve to provide oxygen to all body tissues. Once the different organs have captured the arterial blood oxygen, oxygen-poor blood enters the venous system and returns the right heart. The heart pumps blood through the motions of systole ( atrial and ventricular ) and diastole. Is called the systolic contraction of the heart (either an atrium or a ventricle) to eject blood into the tissues. Diastole is called the relaxation of the heart to receive blood from the tissues.

Discussion

Heart failure

Contrary to popular belief, heart failure is not a disease. Heart failure is called arises due to various reasons state in which the attenuated contractility of the heart muscle (myocardium) and the heart loses the ability to provide the body with the necessary amount of blood (Baldasseroni, Opasich, Gorini, Lucci, 2002). The syndrome of heart failure complicated by a number of diseases of the cardiovascular system, particularly as often the disease occurs in people suffering from coronary heart disease and hypertension. Heart failure in many cases reduces the quality of life and can cause death (Baldasseroni, Opasich, Gorini, Lucci, 2002).

The name "heart failure" is alarming, but it does not mean that the heart has suddenly stopped working. What this means is that the heart is not pumping as it should to carry oxygen-rich blood to the body's cells (Baldasseroni, Opasich, Gorini, Lucci, 2002). Heart failure is usually a slow process that gets worse over time. You may not have symptoms for many years. This slow manifestation and progression of heart failure is ue to ...
