    ObjectiveEvaluate whether the meterological parameters affecting revenues in patients with ST-segment and non-ST-segment elevation ACS.DesignA prospective cohort study was carried out.SettingCoronary Care Unit of Hospital Universitario de Canarias PATIENTS: We studies a total of 307 consecutive patients with a diagnosis of ST-segment and non-ST-segment elevation ACS. We analyze the average concentrations of particulate smaller than 10 and 2.5μm diameter, particulate black carbon, the concentrations of gaseous pollutants and meteorological parameters (wind speed, temperature, relative humidity and atmospheric pressure) that were exposed patients from one day up to 7 days prior to admission.InterventionsNone.Variables Of InterestDemographic, clinical, atmospheric particles, concentrations of gaseous pollutants and meterological parameters.ResultsA total of 138 (45%) patients were classified as ST-segment and 169 (55%) as non-ST-segment elevation ACS. No statistically significant differences in exposure to atmospheric particles in both groups. Regarding meteorological data, we did not find statistically significant differences, except for higher atmospheric pressure in ST-segment elevation ACS (999.6±2.6 vs. 998.8±2.5 mbar, P=.008). Multivariate analysis showed that atmospheric pressure was significant predictor of ST-segment elevation ACS presentation (OR: 1.14, 95% CI: 1.04-1.24, P=.004).ConclusionsIn the patients who suffer ACS, the presence of higher number of atmospheric pressure during the week before the event increase the risk that the ST-segment elevation ACS.Copyright © 2015 Elsevier España, S.L.U. y SEMICYUC.
