'Heart disease linked to job stress'

Scientists have shed light on how stress at work affects the heart, says a study.

The results, published in the 'Scandinavian Journal of Public Health', link this situation to dyslipidemia, a disorder that alters the levels of lipids and lipoproteins in the blood.

Experts have been saying for years that emotional stress is linked to the risk of suffering cardiovascular disease as a result of unhealthy habits such as smoking, an unsuitable diet or leading a sedentary lifestyle, among other factors.

Now, a study conducted by the Sociedad de Prevencion de Ibermutuamur, in collaboration with experts from the Virgen de la Victoria Hospital (Malaga) and the Santiago de Compostela University, analyses the relationship between job stress and different parameters associated with how fatty acids are metabolised in the body.

"The workers who stated that they had experienced difficulties in dealing with their job during the previous 12 months (8.7 percent of the sample) had a higher risk of suffering from dyslipidemia," Carlos Catalina, clinical psychologist and an expert in work-related stress, said.

Dyslipidemia is a lipoproteins' metabolic disorder that can manifest itself in an increase in total cholesterol, low-density lipoproteins (LDLs) and triglyceride levels, in addition to a drop in high-density lipoproteins (HDLs).
