List of Heart Diseases that Result for Heart Function Failure by Al Marketsnipers

As the number one cause of death in the world today, knowing the list of heart diseases may be worth it. Studies reveal that heart disease refers to various chronic and acute conditions which can affect one or more components of a person's heart.

For a clearer understanding of what actually happens when a person suffers from certain heart diseases, we need to understand what the heart is and what goes on with it. According to books, the heart "is a muscular, fist-sized organ". It is situated on the left side of a person's chest cavity. Its role is to pump blood and beat up to around 100,000 times per day. It is the blood that our heart moves that carries oxygen as well as nutrients throughout the body. It also transports carbon dioxide as well as other wastes to the kidneys, liver and lungs for removal. It is the heart's coronary veins and arteries that ensure oxygen supply.

To coordinate heart function with the kidneys and blood vessels, the heart also acts as an endocrine organ. It has the capability to produce hormones like BNP or B-type natriuretic peptide and ANP or astrial natriuretic hormone.

In the inside, the heart is hollow. It has two halves which are vertically divided by a septum. In each side there are two internal chambers which include an atrium (top) and a ventricle (bottom). Through the right atrium, venous blood enters. Then it is pumped to the lungs by the right ventricle. When this happens, carbon dioxide is released and the body acquires oxygen. It is oxygenated blood coming from the lungs that is transported to the left atrium. These are then pumped by the left ventricle to the arteries which carry it around the body. To regulate the flow and direction of blood throughout the chambers, the heart has 4 valves. When they open and close, it is what we hear as the "lub dub" in every heartbeat.

When it comes of the list of heart diseases, these may either be functional or structural. Whatever factors that can damage the heart or decrease its oxygen supply can make the heart less efficient. When its ability to fill and pump is reduced, the heart's relationship with the blood vessels and kidneys are also disrupted. As a result, the heart and the body won't be able to function properly anymore. When this happens, the person may be susceptible to serious, life-threatening conditions.
