| Summary: | The general aim of this thesis was to study symptoms, prehospital delay and time trends in long-term survival in men and women with myocardial infarction (MI). The study was based on quantitative and qualitative data collections. Study I was based on The Northern Sweden MONICA Myocardial Infarction Registry, 1989-2003, including 5072 men and 1470 women with a confirmed MI. Symptoms and prehospital delay were described and trends over time according to sex and age were studied. Typical pain was present in 86% of the men and 81% of the women and typical symptoms were more common among younger persons than older persons. Up to the age of 65 no gender differences were seen in the prehospital delay. In the oldest age group (65–74 years) time to hospital was longer than among the younger group, especially among women. Study II was based on individual interviews with 20 men with a first confirmed MI, representing the age range 65-80 years, about their experiences during the prehospital phase. The interviews were analyzed using qualitative content analysis. The interviewed older men described how the symptoms developed from diffuse ill-being, to a cluster of severe symptoms. The men had difficulties to relate to the experienced symptoms, which did not correspond to their expectations about an MI, and about whether they should seek medical care. By using different strategies the participants initially tried to understand, reduce, or treat the symptoms by themselves, with a desire to maintain an ordinary life. As the symptoms evolved to a persistent and alarming chest pain, the men realized the seriousness in the perceived symptoms, that all strategies were inefficacious and they came to the decision to seek medical care. Study III was based on individual interviews with 20 women with a first confirmed MI, representing the age range 65-80 years, about their experiences during the prehospital phase. The interviews were analyzed using qualitative content analysis. The interviewed older women described how the symptoms were ...
