| Purpose Periprocedural myocardial injury (PMI) following
percutaneous coronary intervention (PCI) has received great
attention due to its significant association with mortality
and morbidity. Accordingly, cardioprotection during PCI is
one of the important therapeutic concerns. Regarding the
potential cardiovascular benefits of pentoxifylline this study
was performed to evaluate whether the pretreatment
pentoxifylline could reduce PMI in patients who are undergoing
elective PCI.
Methods A randomized clinical trial on 85 patients undergoing
elective PCI was performed. The intervention group
(n=41) received 1200 mg pentoxifylline in divided doses plus
the standard treatment before PCI, while the control group
(n=44) received the standard treatment. For assessing myocardial
damage during PCI, the levels of CK-MB and
troponin-I were measured at baseline, 8, and 24 h after the
procedure. Then, patients were followed up for a 1-month
period regarding the major adverse cardiac effect.
Results Comparing with the control group, no significant
change of CK-MB at 8 (p=0.315) and 24 h (p=0.896) after
PCI was documented in pentoxifylline group. Similarly, no
significant change was found in troponin-I at 8 (p=0.141) and
24 h (p=0.256) after PCI.
Conclusions This study could not support the pretreatment
with pentoxifylline in the prevention of PMI in patients undergoing
elective PCI. However, the trend was toward the
potential benefit of pentoxifylline. |
