Wh. Ahmed et al., COMPLICATIONS AND LONG-TERM OUTCOME AFTER PERCUTANEOUS CORONARY ANGIOPLASTY IN CHRONIC-HEMODIALYSIS PATIENTS, The American heart journal, 128(2), 1994, pp. 252-255
The objective of this investigation was to assess the acute and long-t
erm outcome after coronary angioplasty in patients undergoing chronic
hemodialysis. Previous studies have suggested a high incidence of rest
enosis after coronary angioplasty performed in patients with renal fai
lure. Medical discharge abstracts for 8342 patients undergoing angiopl
asty during a 5-year period were searched to identify all coronary ang
ioplasty procedures performed in patients undergoing chronic hemodialy
sis. Procedural and follow-up coronary angiograms were reviewed in a c
ore angiographic laboratory. Hospital records and office visit notes w
ere obtained to assess acute and long-term outcome. Twenty-one patient
s undergoing chronic hemodialysis had been treated by coronary angiopl
asty. The 9 men and 12 women had a mean age of 59 +/- 10 years (range
37 to 78 years) and had been undergoing hemodialysis for 6.2 +/- 6.4 y
ears (range 1 to 19 years). Procedural success was achieved in 12 (57%
) of 21 patients. Three (14%) patients died; 4 suffered nonfatal myoca
rdial infarctions (19%); 1 (5%) required emergency bypass surgery; and
1 (5%) had abrupt vessel closure without complications. Of the 15 (71
%) patients who were discharged with a patent angioplasty vessel, 4 (2
7%) died and 9 (60%) had recurrence of angina within 1 year. Of 9 pati
ents with recurrent angina, 7 underwent a second angiography, and all
showed evidence of restenosis at the previous angioplasty site. The re
sults of coronary angioplasty in these 21 hemodialysis patients sugges
t a high rate of acute complications and poor long-term prognosis in t
his subgroup. Other strategies for revascularization should be conside
red for these patients.
