MYOCARDIAL INFARCTS AND CEREBRAL-VASCULAR ACCIDENTS ASSOCIATED WITH HIGH-TEMPERATURE AND CARBON-MONOXIDE IN A METROPOLITAN-AREA OF SOUTHEASTERN BRAZIL

Many studies have been published about the relationship between life s tyle and genetic risk factors and stroke and heart attack, but there h ave been few about the relationship between atmospheric pollution, spe cifically with carbon monoxide, and temperature and stroke and heart a ttack. With a view to filling this gap the relationship between values of carbon monoxide concentration in the air, maximum and average by d ay, and maximum temperature by day and the number of new cases of CVA and IM admitted as emergencies at the biggest hospital complex of S. P aulo city was analysed. If was concluded, by the use of multivariable regression analysis, that 2.1% and 4.9% of heart attack admissions wer e due to carbon monoxide air pollution and high temperature, respectiv ely. 2.8% of stroke admissions were due high temperature. Stroke and c arbon monoxide were not associated in this population.
