Time trends in incidence of myocardial infarction in male and female dominated occupations in Stockholm, Sweden.

Aims: To investigate time trends in first acute myocardial infarction (MI) incidence in male and female dominated occupations in Stockholm during 1977-1996.

Methods: Population-based case-control study, where all first events of acute MI among participants aged 40-69 in Stockholm 1977-1996 were identified, using registers of hospital discharges and deaths. Controls were selected randomly using national population registers.

Myocardial infarction in Swedish subway drivers.

Objectives: Particulate matter in urban air is associated with the risk of myocardial infarction in the general population. Very high levels of airborne particles have been detected in the subway system of Stockholm, as well as in several other large cities. This situation has caused concern for negative health effects among subway staff.

Creatinine clearance and risk of early mortality in patients undergoing coronary artery bypass grafting.

Objectives: We sought to evaluate renal function assessed on the basis of calculated creatinine clearance as a predictor of early mortality and postoperative complications in patients undergoing coronary artery bypass grafting and to assess whether calculated creatinine clearance is superior to serum creatinine concentration in predicting early death postoperatively.

Methods: Six thousand seven hundred eleven consecutive patients without dialysis-dependent renal insufficiency undergoing a first isolated coronary artery bypass grafting were included. Preoperative serum creatinine concentrations and creatinine clearance calculated by using the Cockroft-Gault formula were related to mortality within 30 days postoperatively.
