Although stress in the work already had been related to cardiac diseases, still was not understood well why. But this new study, conducted in 10.308 English state workers of between 35 and 55 years throughout a period of 14 years, indicates that there is a direct relation between labor stress and the metabolic syndrome (SM), that as well leads to the diabetes and cardiovascular diseases.

The investigation is published in the last electronic edition of the Medical British Journal. "one is a very serious and complete work, that includes to a great amount of working public which it studied during many years. The indicators are alarming, since they detected that more of the double of the state employees under labor stress they suffer of metabolic syndrome, a condition that derives in cardiovascular problems and diabetes ", affirmed to the NATION doctor Daniel Lopez Rosetti, president of the Society Argentina de Medicina of Stress.

According to the Medical Association of the Heart of the United States, the metabolic syndrome is a clinical picture that is demonstrated when three of the five factors of metabolic risk in a patient are detected: arterial hypertension (more than 85 and 130 millimeters of mercury of minim and Maxima, respectively), diabetes type 2 (noninsulinodependiente, he is commonest), triglicéridos increase of the level of (greasy sanguineous), diminution of the HDL-cholesterol or lipoprotein of HD (good cholesterol) and central obesity.

The scientific work, based on clinical and psychological studies, measured labor stress in four opportunities between 1985 and 1999. The components of the metabolic syndrome, such as obesity, hypertension and stops cholesterol levels were moderate between 1997 and 1999. Also the social position of the employee and the injurious behaviors for the health considered, such as to smoke, to take in excess and the lack of exercise (...).

Hormonal imbalance

The conclusions at which it arrived the team of English investigators demonstrated that the exhibition prolonged to stress in the work affects the nervous system diminishing the biological resistance and disturbing the natural physiological balance of the organism (homeostasis). The association between the metabolic syndrome and the exhibition to injurious behaviors for the health was greater between men than between women. A poor diet (without consumption of fruits and vegetables), to smoke, to drink in excess, and the physical inactivity was all tie behaviors with more risk of suffering this picture.

"There is a imbalance of the independent nervous system and the neuroendocrino system product of the ascent of the levels in blood of hormones of stress: cortisol (it promotes the increase of sugar in blood and diminishes the defenses infectious agents in front of) and sanguineous noradrenaline (it increases to the cardiac frequency and the arterial hypertension)", added Lopez Rosetti.

This way, according to the specialist, to see itself put under a chronic labor stress produces the liberation of proinflammatory substances and protrombóticas, that generate isquemias cardiac, they increase the coagulation sanguineous and they take to the patient to cardiac insufficiencies, arrhythmias and infarcts and to accidents directly cerebrovasculares (ACV).

"most important of this study it is that it ties labor stress with the cardiac diseases through metabolic syndrome. When the labor load is more intense of which a person can support, the body and the mind begin to show exhaustion symptoms. The body whispers to us in the beginning, soon speaks to us and in the end it shouts to us ", concluded Lopez Rosetti.
