Background

Coronary no reflow is infrequent complications during percutanous coronary intervention (PCI), however its impact on long term clinical outcome is not well studied.

Methods

A total 1926 all comer patients (pts) including acute myocardial infarction (MI) pts who underwent PCI with DESs were enrolled for this study. Study population was divided into two groups; "no reflow" group (n=50 pts) and non "no reflow" group (n=1876 pts). Angiographic at 6 months and clinical outcomes up to 24 months were compared between the two groups.

Results

Baseline characteristics were similar between the two groups. The incidence of angiographic no-reflow was in 2.6% (50/1926). At 6 months, "no-reflow" group had more incidences of higher late loss. At 24 months clinical follow up, the "no-reflow" group had worse clinical outcomes including higher cumulative incidence of total death, Q-MI and major adverse cardiac events (MACEs, Table).

Conclusions

In the current study, despite of low incidence of "no-reflow" in general PCI population, those patients had worse angiographic and clinical outcomes up to 24 months. Special care should be exercised in this particular subset of pts during and after the procedure.
