Patient Information on Heart Diseases


Smoking has been strongly associated with respiratory problems and malfunctioning of the lungs. But did you know most heart diseases are caused due to smoking? Here is some related information on heart diseases caused due to smoking. Let us take a look at what actually happens when a person smokes. Hopefully the provided information on heart diseases will frighten smokers and they will give up on smoking.


When a person smokes the lungs are unable to oxygenate the blood that flows into the heart. The lungs are full of blood vessels which absorb oxygen and then take this oxygenated blood to the heart so that it may be pumped through to the various parts of the body. However, when a person smokes – the smoke destroys the blood vessels and this reduces the lungs’ capacity to absorb oxygen. This requires a person to breathe harder because there is a constant oxygen deficiency in the blood. If a chain smoker jogs for even just a couple of minutes, then he is bound to fall short of breath. This puts tremendous pressure on the heart – the heart needs to beat faster to ensure that the body receives enough oxygen as the concentration of oxygen in the blood is low. Let us consider a particular case: There is a certain individual who is a non smoker. In the normal state, his heart has to beat at the rate of 72 times per minute to ensure that his body receives a sufficient quantity of oxygen. However, if this individual becomes a smoker - the blood vessels in his lungs will be damaged by the cigarette smoke. Thus, his lungs will absorb a lesser amount of oxygen than before. In order to ensure that his body receives sufficient oxygen, that individual’s heart has to beat at a higher rate (say 100 times per minute). The heart has to work harder to achieve the same result as before. This puts a considerable strain on the heart and often causes irregular heartbeats. Heart diseases among smokers are also a result of the fact that smoking causes the blood to become infested with nicotine and other carcinogenic substances.


Other heart diseases caused due to smoking include the dreaded condition of atherosclerosis. Atherosclerosis is state where arteries harden. Arteries are the nerves which carry oxygenated blood to all parts of the body. Smoking also causes include deposition of plague (a wax- like substance) on the inner walls of the arteries. This reduces the radius of the arteries and makes it difficult for blood to flow through them. Thus, the heart has to work even harder to make sure that the blood is pumped through the arteries. Hypertension is just one of the many heart diseases caused due to smoking.

You will come across many such information on heart diseases caused due to smoking on the internet. Coronary heart disease is a result of hardening of the coronary arteries – this is a serious condition and can lead to a heart attack. Smoking also destroys the heart tissues and lowers the amount of good cholesterol in the blood. It is necessary that smokers read information on heart diseases, this way they will realize the implications of smoking.

Tips and comments

This information on heart diseases should open all smokers’ eyes, and dissuade them from smoking. Over time, the cells of the lungs recuperate and once more become capable of absorbing a sufficient quantity of oxygen.
