Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

AIM: To study the influence of environmental factors (EFs) on the development of cardiovascular diseases in the population of industrial towns of the Republic of Kazakhstan. SUBJECTS AND METHODS: The investigation covered an 18-59-year-old adult population who had been living in the urbanized areas of the Republic of Kazakhstan for at least 10 years, who worked in harmless conditions and were unregistered as having chronic diseases. At Stage 1, screening (a therapist's examination, blood general and immunological tests, and electrocardiography) was carried out for risk group persons who underwent in-depth clinical examination (blood biochemical test) at Stage 2. RESULTS: Multivariate statistical analysis has revealed that the development of hypertension is associated with the high concentration of sulfur dioxide in atmospheric air, copper in dust sediments, and zinc in soil and that of coronary heart disease (CHD) is related to the high levels of nitrogen dioxide in atmospheric air and zinc in dust sediments. CONCLUSION: Based on pathogenetic and statistical data and information available in the literature, hypertension and CHD are referred to as the diseases that may result from the influence of EFs.
