The effect of secondary inorganic aerosols, soot and the geographical origin of air mass on acute myocardial infarction hospitalisations in Gothenburg, Sweden during 1985-2010: a case-crossover study (29 page pdf, Janine Wichmann, Karin Sjöberg, Lin Tang, Marie Haeger-Eugensson, Annika Rosengren, Eva M Andersson, Lars Barregard and Gerd Sallsten, Environmental Health, Jul. 29, 2014)
Key Quotes:
“Acute myocardial infarction (AMI) is the most important manifestation of ischemic heart disease. The major risk factors for CVD [cardio-vascular disease] are age, sex, smoking, low physical activity, increased waist circumference, diabetes and hypertension …Evidence is increasing on the effects of nontraditional risk factors, such as air pollution and weather (e.g. temperature) on CVD mortality and morbidity, specifically as short-term risk factors”
“The REVIHAAP report concluded that there is currently no threshold level (i.e. no safe level) for PM10, PM2.5, nitrogen dioxide (NO2) and ground-level ozone (O3) and that the concentration-response functions are mostly linear”
“Locally generated PM (PMrest) is associated with an increase in AMI hospitalisations during 1990–2000 in the cold period, whilst days with limited local dispersion within Gothenburg were important during 2001–2010, also in the cold period. Altogether this indicates the significance of local emissions from e.g. traffic within Gothenburg.”
