Heart Disease - Introduction

Any medical ailment that occurs to the heart is termed as heart disease. In these times, it has become quite a norm to succumb to such conditions. A good share of the population will contract one or other form of heart disease. The trend is catching up all over the globe. A recent survey conducted in some of the developed nations has revealed a starling fact. Every 34 seconds, at least one person is succumbing to heart disease. In the light of this situation, it is imperative that one must have a good notion about the importance of heart and the measures to prevent the occurrence of heart diseases.

In our primary classes, we have learned quite a bit about heart and its related functions. The heart has two core functions. It deals with the pumping of pure and impure blood. Essentially, it pumps oxygen-enriched blood from the lungs to various parts of the body. The lungs help in the re-oxygenation of the impure blood. The auricles and the ventricles act in unison to pump out oxygen-enriched blood and to collect oxygen-depleted blood. The chambers present in the right quadrant of the heart deals with the impure blood while the other two chambers deal with the pumping of pure blood across the body.

Heart diseases are of diverse types. Coronary heart diseases occupy the top slot. Failure of the coronary circulation is the underlying factor for this condition. However, it can lead to heart attacks - a vexing condition. The muscles of the heart (otherwise termed as the myocardium) can also fail to function in an appropriate manner. It causes cardiomyopathy. There exists intrinsic and extrinsic cardiomyopathy. Plenty of blood vessels supply blood from various parts of the body to the heart. Medical ailments occurring to these vessels can lead to cardiovascular diseases.

We have already seen that the heart acts as an effective instrument to pump blood into various parts of the body. Restriction of this core functionality can impair the functioning of some other organs. Ischemic heart disease - this is the term used to specify this condition. Heart failure is another condition that has been plaguing the modern generation since some decades. The high blood pressure levels within the body can lead to hypertension; this will eventually lead to another kind of heart disease. The inflammation of the muscle tissues might occur. It will affect the normal functioning of the heart. Such conditions can also lead to heart diseases.

The auricles and the ventricles are separated from each other with the aid of valves. Ailments of these valves can cause heart diseases, likewise. There was a time when physicians used to attribute heart diseases to the unhealthy lifestyle lead by the present generation. However, the recent discoveries are proving something else - our hearts are programmed to failure at some part of our lives. Researchers have found direct links to heart disease causing elements in the DNA. At the same time, awareness of the various kinds of heart diseases and the factors that trigger them play a pivotal role in warding them off.
