Blood Pressure in the Emergency Department

This is a cohort study based on a large sample (\> 600 000) of emergency department (ED) visits from two university hospital EDs. Information on incident disease after discharge from the ED will be collected through linkage to Swedish national in-patient register and cause of death register. The importance of blood pressure measured at the ED for incident atherosclerotic cardiovascular disease during long term follow up will be studied by Cox-regression analysis
