The effects of angiotensin converting enzyme inhibitors and angiotensin receptor blockers (ACEI/ARBs) on angiogenesis, myocardial remodeling and intermittent claudication have been studied. Clinical studies have shown reduced re-intervention after cardiac stenting with the use of ACEI/ARBs. We hypothesized that the use of ACEI/ARBs decreases re-interventions after endovascular revascularization in tibial artery disease (TAD) patients. This is a retrospective study comparing the effects of ACEI/ARBs on the outcomes after endovascular revascularization for TAD. We divided all patients that underwent endovascular revascularization into Angiotensin converting enzyme inhibitor/Angiotensin receptor blockers (ACEI/ARBs) and No Angiotensin converting enzyme inhibitor/Angiotensin receptor blockers (NoACEI/ARBs) groups. A total of 360 patients underwent endovascular intervention for TAD. One hundred and ninety-six (54%) patients, 124 (57%) males, were on ACEI/ARBs after endovascular intervention for TAD, whereas 164(46%) patients, 87 (53%) males were not. The groups were well matched in the demographic variables except higher incidence of congestive heart failure, coronary artery disease and dialysis in the ACEI/ARBs group (p = .001, 0.02, 0.01 respectively). Reintervention rates were not associated with ACEI/ARBs use (p = .097). Even when corrected for statin use and antiplatelet therapy, no difference was seen in the reintervention rates in the two groups (p = .535, 0.547 respectively). Primary patency, assisted primary patency and secondary patency did not differ with the use of ACEI/ARBs (p = .244 0.096,0.060 respectively). No difference was seen in overall survival between the two groups (p = .690). ACEI/ARBs do not appear to affect the patency and reintervention rates for patients undergoing endovascular revascularization for TAD.
