Air pollution and hospitalization due to angina pectoris in Tehran, Iran: a time-series study.
Health effects of air pollution have been studied in many different parts of the world. Although a fairly large number of studies have explored the cardiovascular impacts of air pollution, because of its unique location we studied the association between air pollutants and hospital admissions due to angina pectoris in Tehran for the first time. ⋯ We found that with increasing levels of the pollutant CO, the number of admissions due to cardiac angina rose. Ischemic heart disease is the leading cause of death in Iran. Air pollution control will reduce the number of this preventable disease and resulting deaths.

The majority of women living in rural areas in Turkey use biomass fuels for domestic energy and are exposed to high levels of indoor air pollution every day. The objective of this study was to compare the presence of chronic airway diseases (CAD) in two groups of nonsmoking women older than 40 years with (exposed group, n=397) and without a history of exposure to biomass cooking (liquid petroleum gas (LPG); control group, n=199), in 2002 in Kirikkale, Turkey. Detailed respiratory symptoms were collected with a standard questionnaire adapted from that of the British Medical Research Council. ⋯ Acute symptoms during exposure to biomass smoke were important predictors for the presence of CAD. Biomass smoke pollution is an important contributing factor in the development of CAD in nonsmoking women living in a rural area. The presence of acute symptoms during cooking in women in rural areas should signal to general practitioners the possibility of CAD.
