Air pollution - one of principal causes of heart troubles
Physicians frequently consider that the reasons of heart troubles are genetic factors or a way of life. Now the American experts have defined that air which we daily inhale in a city, also can serve one of the main reasons of development of warm problems.

Ecologists of University of Louisville and Michigan university have fixed that increase of concentration in air of polluting substances is connected with growth of cases of warm death and heart attacks. Research was spent in 250 cities worldwide in which result it has been established that in places with high indicators of substances polluting air people died earlier, in most cases because of heart diseases. Growth of concentration of harmful substances in air was directly proportional to growth of number of heart attacks. The most vulnerable group were cores and older persons, and also sick of a diabetes, women and the people suffering from adiposity.

According to cardiologists, microscopic particles of polluted air get to lungs and then get into a blood-groove, breaking work of cardiovascular system. Most of all harm can cause ozone, nitrates, sulphates, metals and aldehydes, experts have concluded. In particular it has been proved that aldehydes - the toxic class of chemical substances containing in the majority of kinds of a smoke, including cigarette and in exhaust gases of cars, - raises cholesterol levels in blood and activates enzymes which form plaques and blood clots on the blood vessels, blocking arteries and promoting heart attack. Within 15 minutes after inhalation ultrathin   particles arterial pressure, therefore bad ecology of air quickly raises can bring the negative contribution and to increase in sphere of action of a hypertension. Doctors explain that blood vessels react on Air pollution, making the inflammatory answer at activity of extraneous substances. Clinical physicians recommend to inhabitants of megacities to try not to happen in the street in rush hours near to motorways and highway and to go in for sports in the closed premises, where air is filtered to avoid additional loading on heart.
