Spanish scientists reveal the dangers of haze: for these reasons it can be fatal

Canarian researchers have discovered that exposure to haze is directly associated with an increased risk of death from a cardiovascular accident. The study places the increased risk of death due to these causes at 2%.

The study in question has been carried out by a multidisciplinary team of cardiologists, biochemists and atmospheric physicists, led by the Cardiology Service of the Hospital Universitario de Canarias, headed by Alberto Domínguez, and with the participation of the Higher Council for Scientific Research , the Central University Hospital of Asturias, and the University of La Laguna, among other institutions.

Specifically, those responsible for the discovery, Alberto Domínguez, Sergio Rodríguez, Néstor Baez-Ferrer, Pedro Abreu-Gonzalez, Rocío Díaz, Pablo Avanzas and Daniel Hernández-Vaquero warn that at a global level, there is a clear association between exposure to dust desert and cardiovascular mortality, so that an increase of 10 micrograms per cubic meter of air in the concentration of desert dust in ambient air is associated with this percentage of mortality from cardiovascular disease.

The results of this study, based for the first time on a systematic review and meta-analysis, would also help to alert the most sensitive population to take appropriate measures during desert dust episodes, and it included studies conducted in Asia, Europe, the Middle East and North Africa. The results of this first analysis conclude that desert dust also increases the risk of cardiovascular death one day and two after exposure, although the effect is less.

In recent years, the scientific community has become interested in the possible health effects associated with inhaling respirable desert dust.and. Previous epidemiological studies have observed increases in morbidity and mortality during desert dust episodes in Southern Europe and Asia.

Statistical power in time series studies that analyze the influence of desert dust on health effects is a very common and undervalued problem, for this reason these researchers decided to carry out the present study through a systematic review and meta-analysis to demonstrate the influence of dust. desert in cardiovascular problems.

This study has been published in the Journal of Clinical Medicine.
