Abstract(s)
Previous studies suggest that human exposure to atmospheric pollution can trigger cardiovascular diseases (CVDs). This study aimed at
assessing the influence of short-term exposure to
atmospheric pollution in the occurrence of CVD
and mortality in Madeira. A single-centre retrospective study was conducted during 2005–2011. Air
pollutant data and meteorological parameters were
gathered. Daily admissions at the emergency service
due to CVD and markers levels for cardiac function
were obtained from a public hospital. Exploratory
and correlation analysis of all variables were performed, and the CVD relative risk (RR) of hospital
admissions and mortality was calculated. During the
study, mean annual concentrations of the air pollutants varied greatly, with NOx and O3 showing the
highest annual average concentrations. Two hundred
ten thousand five hundred forty patients were admitted at the emergency service, 74% of them due to
cardiovascular causes. Hospital admissions were
positively correlated with PM2.5, and SO2. A positive and significant association between PM2.5 with
creatine kinase myocardial band and B-type natriuretic peptides markers was found, whilst SO2 was
positively associated with Creatine kinase myocardial band. The RR seemed to increased with PM2.5
and NOx exposure. Traffic-related pollutants were
weakly but statistically associated to hospital admissions due to CVD and mortality. PM2.5 and SO2
were related with higher hospital admissions which
in turn seemed to increase the serum markers. The
risk of mortality was mainly associated with O3 and
average air temperature. Adults and elders seem to
be more susceptible to atmospheric pollutants, particularly in the winter.
