Nosocomial septicaemias were studied in a cardiologic ward at the Univ
ersity Hospital of Antwerp, Belgium. The incidence of nosocomial infec
tions was found to be 2.7 per 1,000 admissions per year. A case-contro
l study suggested that in contrast with coronarography and pacemaker i
mplantation, percutaneous transluminal coronary angioplasty may be a r
isk factor for nosocomial septicaemia (OR 4.5, 95% confidence interval
0.7-33.4).
