Air pollution and ST-elevation myocardial infarction treated with primary percutaneous coronary angioplasty: A direct...

Area of Science:

• Environmental Health
• Cardiology
• Public Health

Background:

• Air pollution is a growing concern for public health.
• The impact of specific air pollutants on acute cardiovascular events like ST-elevation myocardial infarction (STEMI) requires further investigation.
• Primary percutaneous coronary intervention (PCI) is a critical treatment for STEMI.

Purpose of the Study:

• To assess the relationship between daily air pollutant concentrations and hospital admissions for primary PCI in STEMI patients.
• To investigate the correlation between atmospheric pressure and STEMI admissions.
• To determine if air pollutant levels exceeding safety thresholds are associated with increased STEMI incidence.

Main Methods:

• Retrospective analysis of medical and instrumental data from January 2012 to March 2016.
• Inclusion of patients admitted with STEMI and treated with primary PCI.
• Collection of daily atmospheric pressure and air pollutant data (NO2, PM10, O3, SO2, CO) from a regional meteorological service.

Main Results:

• STEMI patients treated with primary PCI were more frequent with atmospheric pressure > 1013.15 hPa (61.8%).
• High incidences of STEMI admissions occurred when NO2 (83.1%), PM10 (52%), and O3 (8.5%) exceeded safety thresholds.
• Significant positive correlations were observed between daily STEMI admissions and daily levels of NO2 (r=0.205), PM10 (r=0.349), and O3 (r=0.191).

Conclusions:

• A direct and significant correlation exists between daily STEMI admissions and daily concentrations of NO2, PM10, and O3.
• Elevated levels of these air pollutants may contribute to an increased incidence of STEMI requiring primary PCI.
• Findings underscore the importance of air quality monitoring in cardiovascular health management.
