Introduction: Several studies have suggested a relationship between traffic noise and ischemic heart Disease, in particular acute myocardial infarction (MI). Objectives: To analyse the association between residential exposure to road traffic noise and MI incidence in Pisa, Italy. Methods: Incidence of first MI in the period 2002-2006 was obtained from mortality and hospitalization data (1998-2006). Residential address and geographical coordinates was available for each subjects together with age and gender data. Traffic noise exposure was estimated at the buildings façades of the house of each subjects from the 3D noise maps of Pisa. The exposure estimates were done by Environmental Protection Agency of Tuscany Region according to the new acoustic indicators and interim methods issued by European Directive 2009/49/CE. Results: 823 MI cases were identified in 2002-2006 (480 males) among 12,710 residents (5774 males) living in 1,296 different buildings. Incidence rates were computed by sex, age groups (30-49;50-69;70+ years) and nocturnal noise levels (<55Db;=>55Db). MI incidence rates were higher among males living in building with high level of nocturnal traffic noise exopure (=>55Db): the rate ratio between high/low noise levels was 1.08 at age 30-49, 1.19 at age 50-69, 1.35 over 70 years . Among women MI incidence rates were about 50% lower than those of male and with similar trend by age. Conclusions: This preliminary results support the presence of an association between occurrence of first myocardial infarction and high leves of nocturnal traffic noise exposure at the place of residence. Further analyses should consider the residence duration and the possibility of confounding from air pollution exposure and socioeconomic status
