Introduction:

The generation of electrical energy constitutes one of the most important indicators of development of a nation. In this process, extremely low frequency electromagnetic fields are generated, which could affect the heart.

Objective:

To identify the association between global cardiovascular risk and exposure to extremely low frequency electromagnetic fields.

Methods:

A cross-sectional, descriptive study was carried out in the Health Area November 27, of the Marianao municipality of Havana province, in 2018. The sample consisted of 152 individuals. The cardiovascular risk was determined, according to the Gaziano predictive tables without laboratory. Measurements of magnetic flux densities were made in their homes. It was assessed whether these were associated with the intensity of electricity generation at the neighboring thermoelectric plant and with the overall cardiovascular risk of the residents. Spearman's non-parametric correlation was used.

Results:

31,6% of the studied population was evaluated with high and very high cardiovascular risk as a whole. 120 individuals were exposed in their homes to magnetic flux densities between 0 and 0,9 µT. There was a statistically significant correlation between the intensity of the current generated by the industry and the magnetic flux densities in the rooms used to sleep.

Conclusions:

No association was observed between the cardiovascular risk and the magnetic flux densities measured in the dwellings. Exposure to extremely low frequency electromagnetic fields was not a cardiovascular risk factor for the population studied.
