Therapy

Consider giving intracoronary gamma radiation therapy following opening of stenosed coronary stents ^a  

Why?

• Patients undergoing PTCA for restenosis of a coronary stent who received intracoronary gamma radiation therapy compared with placebo are less likely to die, have a myocardial infarction or require revascularisation. ^a

Angioplasty: intracoronary stent gamma radiation therapy reduces cardiac events

Patient a	Treatment	Comparison	Outcome	CER	RRR (95% CI)	NNT (95% CI)
angioplasty for stenosed stent	intracoronary gamma radiation therapy	placebo	death, MI or revascularisation at 9 months	44%	36% (9% to 54%)	6 (4 to 26)
