According to a study published in the medical journal British Medical Journal (BMJ), rates of mortality caused by coronary heart disease have declined significantly in the UK since the early ’70s, resulting in substantial improvements the average life.

Experts attribute these improvements to conditions such as the fight against smoking, changes in dietary patterns and lifestyles, and improved treatments for those affected by cardiovascular disease.

To date, previous studies had not taken into account the extent to which affected the life expectancy of different risk factors for cardiovascular disease.

But a group of researchers at the University of Oxford (United Kingdom), led by Robert Clarke, focused on studying the association between these factors and life expectancy in the so-called “middle-aged men (between 40 and 69 years) .

The study participants completed an initial questionnaire which indicated their medical history, habits to snuff, its degree of professionalism and their civil status, in addition to record your weight, height, blood pressure, lung condition, level cholesterol and glucose in the blood.

These men were examined for the first time between 1967 and 1970.

Experts tracked to 18,863 of these men, of whom 7044 were alive in 1997, the year in which re-examined (28 years after the first evaluation).

At the beginning of the study, noted that 42 percent were smokers, a 39 percent jump tension and that 51 percent had high cholesterol level.

When they returned to be evaluated, approximately two thirds had quit smoking and experts registered a two-thirds reduction in blood pressure and cholesterol levels.

The study found that after the age of 50 years, individuals who suffered simultaneously the three risk variables (snuff, high blood pressure and cholesterol) were reduced in 10 years life expectancy compared to males who arrived at the same age did not show any of these factors.

The average life of 23.7 years stretched first (to 73.7) and 33.3 years for the latter (up to 83.3).

These projections were made from a more detailed scale that took into account jointly the following: smoking, diabetes, employment status, continuous measurement of blood pressure levels and cholesterol levels and body mass index.

In the highest risk of this scale was placed on 5 percent of less healthy individuals, whose life from the 50 was prolonged 20.2 years (to 70.2), while lower appeared another 5 percent, whose life was prolonged over 15 years: a total of 35.4 (to 85.4).
