Impact of Guideline-Directed Medical Therapy on 2-Year Mortality in Japanese Patients Undergoing Endovascular Therapy for Femoropopliteal Lesions　- Results of the Multicenter GEMINI-FP Study.

BACKGROUND

The effect of guideline-directed medical therapy (GDMT) on mid-term mortality in Asian patients, including Japanese patients, who have undergone endovascular therapy (EVT) for lower extremity artery disease remains still unclear. This study evaluated the effects of GDMT, defined as the combined prescription of antiplatelet agents, statins, and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, on 2-year mortality in Japanese patients undergoing EVT for femoropopliteal (FP) lesions.

METHODS AND

RESULTS

In this multicenter retrospective study, 1,756 registered patients were divided into 2 groups: those who received all 3 medications that comprised GDMT (full GDMT group) and those who received ≤2 medications (non-GDMT group). After propensity score matching, the baseline characteristics did not differ significantly between the 413 pairs of participants in the full GDMT and non-GDMT groups. All-cause mortality within 2 years was significantly lower in the full GDMT than non-GDMT group (14.3% vs. 20.8%; log-rank P=0.030). Mortalities from cardiovascular and cardiocerebrovascular diseases within 2 years were also significantly lower in the GDMT group (4.2% vs. 9.5% [log-rank P=0.021] and 4.2% vs. 10.5% [log-rank P=0.007], respectively).

CONCLUSIONS

In Japanese patients undergoing EVT for FP lesions, GDMT may improve all-cause, cardiovascular, and cardiocerebrovascular mortality within 2 years.
