Exhaust Gases of Vehicles and Heart Disease: Two Interesting Study Results

This article is about two different and somewhat contradictory results from two different studies conducted by experts. One says that inhaling vehicle exhaust gases by heart patients increases the risk of heart attack in them. The other study result has something different to say. It says that toxic gases like carbon monoxide and nitric oxide found in exhaust fumes of vehicles can be effectively used to prevent blood clots by widening blood vessels of heart patients.

A Study Shows that Excessive Exposure to Exhaust Gases Raise Heart Attack Risk
Experts from the UK have found out that if a heart patient breaths in vehicle exhaust gases heavily, it can cause a heart attack in him. The risk of heart attack will be high for about six hours after the exposure. It only speeds up the possibility, but doesn’t become a direct cause for heart attack.

Repeatedly getting exposed will not be good for health and life expectancy may get considerably decreased. The study was co-funded by the British Heart Foundation. An Associate Medical Director of the Foundation, Professor Jeremy Pearson said that the risk of a heart attack would increase temporarily after a heavy exposure to exhaust gases and it would last for about 6 hours. After that period the risk is expected to go down.

He was also quoted as saying that pollution had a considerable effect on the health of the heart as it is capable of thickening the blood and thus increasing the chances of a blood clot. He was of the opinion that unhealthy food habits, smoking etc. were more serious factors than pollution when risk for a heart attack was considered.

Another Study Shows that Some Exhaust Gases Can be used to Reduce Heart Attack Risk
Some British experts are experimenting to find the possibility of curing heart disease using some toxic gases found in the exhaust fumes of vehicles. Carbon monoxide and nitric oxide are two of the toxic gases found in the exhaust fumes of vehicles. Prof. Ian Megson and his assistants are working on how these gases can be used to prevent clotting of blood by widening the blood vessels.

Prof. Megson was quoted as saying that when minute quantities of these toxins are released into ones heart, it widens the arteries and also decreases the clotting ability of blood, thus easing the flow of blood.

Just see the results of the two studies. The first one makes the exhaust fumes of vehicles a villain and the second one makes it a savior. What are we to believe? I think both may be true. Poison can also make remedy, provided we apply the right quantity!
