A word about prevention
Until now, scientific knowledge regarding the significance of
risk factors has shown that approximately 50% of heart attacks are
caused by modifiable risk factors. Recently, the INTERHEART study,
published in the prestigious medical journal. The
Lancet, revealed some very significant results. The study involved
29,000 individuals in 52 countries around the world.
The results of the study show that in 90% of cases, the
occurrence of an infarct could be explained by the six following
risk factors: smoking, high cholesterol, high blood pressure,
diabetes, abdominal obesity (a waist measurement of more than 100
cm for men and of more then 88 cm for women) and stress.
Moreover, three factors play a protective role: a diet rich
in fruits and vegetables, physical activity, and modest consumption
of alcohol (one to two drinks per day). Once again, the results
confirm how important prevention is in terms of decreasing the risk
of heart attack. As well, this was the first time that stress was
convincingly shown to be a risk factor for heart disease.
