The present study was conducted to evaluate the incidence of CK-MB elevation and to identify the possible mechanisms of CK-MB release after various coronary interventional devices. We prospectively studied 1,675 consecutive patients following various coronary interventions for CK-MB elevation, from January 1997 to February 1998 and followed them for in-hospital events. CK-MB elevation was detected in 313 patients (18.7%); with 1-3 x normal in 12.8%, 3-5 x normal in 3.5%, and >5 x normal in 2.4%. CK-MB elevation was more common after nonballoon devices (19.5% vs. 11.5% after balloon angioplasty; P < 0.01). Among the newer nonballoon devices, rotational atherectomy alone had a lower CK-MB elevation compared to stent-alone group (16.0% vs. 20.5%; P = 0.07). On univariate analysis, due to selective use of abciximab in high-risk coronary interventions, there was higher incidence of CK-MB elevation with abciximab (24.5% vs. 15.0% without abciximab; P < 0.01). Some kind of procedural complication was observed in 49% of the CK-MB elevation group, with side-branch closure being the most frequent (22.7%). In conclusion, CK-MB elevation is common after successful coronary interventions and is higher after nonballoon devices. Cathet. Cardiovasc. Intervent. 48:123-129, 1999.
