To the Editor: I have several concerns about
the study of Dr Kay and colleagues.1 First,
the authors reported a length of hospitalization of 3.9 days in control group
and 3.4 days in the acetylcysteine group. In a previous study that analyzed
contrast nephropathy after elective coronary angiography with or without intervention,
the length of hospitalization in the control group was only 1.3 days.2 It would be of interest to know why the length
of stay was so much longer in the study by Kay et al, especially as there
were only 2 complications reported and none of the participants required dialysis.
It also would be of interest to know the management of patients with acute
contrast-induced reduction in renal function.
