Aim of study: to evaluate possible seasonal variantion in men and women hospitalization and case-fatality rates of acute myocardial infarction in Vilnius University Hospital Santariskes Clinics, Cardiologic Reanimation and Intensive Care unit during the 2000 – 2010 years period. Materials and methods: we analysed 15333 hospitalized due to acute myocardial infarction patients cases. Median age was 72 ± 1,5 years. 931 patients deaths were caused by the acute myocardial infarction during the exploring period. There were estimated hospitalization and deaths from acute myocardial infarction rates through the four seasons. Results: there were observed 7 % – 10% more men died from acute myocardial infarction in spring and 8% – 11% more in autumn, rather than number of the deaths in winter or summer. In the women group 10% – 11% more died in spring and 12% – 13% in autumn, compare with other seasons. Conclusions: study demonstrated the significant seasonal variation in the hospitalizations rates and deaths from acute myocardial infarction, with more common morbidity in March – April – May and higher mortality rate in March – April and in September – October – Noverber months. Patients older than 55 years have approximately 3,5 – 4,5 times higher mortality due to acute myocardial infarction risk, compare with younger patients. in LIthuanian
