Key Takeaway
Stepwise DAPT de-escalation shows no significant difference in NACE compared to standard DAPT in patients undergoing DCB.

This prespecienced subgroup analysis of the REC-CAGEFREE II trial involved 1,948 patients with acute coronary syndrome (ACS) undergoing drug-coated balloon (DCB) angioplasty. The study compared stepwise dual antiplatelet therapy (DAPT) de-escalation against standard DAPT in patients with both multivessel and single-vessel disease.

Analysis revealed that multivessel disease was associated with a significantly higher risk of net adverse clinical events (NACE) compared to single-vessel disease. Specifically, the multivessel group showed a 12.5% NACE rate versus 6.7% in the single-vessel group, indicating a higher baseline risk for these patients.

When comparing the two treatment strategies, no statistically significant difference in NACE was observed between stepwise de-escalation and standard DAPT in either the multivessel or single-vessel cohorts. The results suggest that de-escalation is a viable alternative to standard protocols for patients undergoing DCB-only interventions.

Clinicians can consider stepwise DAPT de-escalation as a safe alternative to standard DAPT for patients with ACS treated with drug-coated balloons. The findings suggest that the choice of de-escalation strategy does not significantly alter the risk-benefit profile regardless of the number of vessels involved.

Researchers looked at how different blood thinning strategies affected patients with acute coronary syndrome. The study included nearly 2,000 patients who underwent a specific type of angioplasty to treat blocked arteries. They compared a stepwise de-escalation method to a standard dual antiplatelet therapy (DAPT) over a 12-month period.

The results showed that patients with multivessel disease had a higher risk of adverse events compared to those with single-vessel disease. However, when comparing the two different treatment methods, there was no significant difference in safety or outcomes between the stepwise de-escalation and the standard treatment for either group.

Because this was a prespecified subgroup analysis of a larger trial, the findings are specific to this study's design. While the results suggest that both treatment paths have similar risk profiles, patients should talk to their doctors to determine the best medication plan for their specific heart condition.

What this means for you:
Stepwise de-escalation of blood thinners showed similar safety results to standard treatment for heart patients.

Common questions

Is the new treatment safe for patients with heart disease?

The study found no significant difference in net adverse clinical events between the stepwise de-escalation and standard treatment. This applies to both patients with single-vessel disease and those with multivessel disease. Because the results were similar, both methods showed comparable risk-benefit profiles over a 12-month period.

How did the risk differ for patients with multiple blocked vessels?

Patients with multivessel disease had a significantly higher risk of adverse events compared to those with single-vessel disease. Specifically, the multivessel group had a 12.5% rate of events compared to 6.7% in the single-vessel group. However, the specific type of blood thinner treatment did not change this risk level.

What are the main takeaways from this study?

The study suggests that stepwise de-escalation and standard dual antiplatelet therapy (DAPT) have similar outcomes for patients undergoing drug-coated balloon angioplasty. Since this was a prespecified subgroup analysis, it provides a specific look at these groups, but you should consult a doctor for personalized medical advice.

BACKGROUND The optimal antiplatelet regimen in patients with acute coronary syndrome (ACS) and multivessel disease undergoing drug-coated balloon (DCB) angioplasty remains unclear. METHODS This was a prespecified subgroup analysis of the REC-CAGEFREE II trial, which was conducted at 41 sites in China and randomized 1948 exclusively DCB-treated participants with ACS to stepwise dual antiplatelet therapy (DAPT) de-escalation or standard DAPT. The primary endpoint was net adverse clinical events (NACE; including all-cause death, stroke, myocardial infarction, revascularization, and BARC type 3 or 5 bleeding) at 12 months. Participants were stratified into multivessel and single-vessel subgroups according to angiographic characteristics. RESULTS Overall, 720/1948 (37.0%) patients had multivessel disease. The multivessel subgroup was associated with a significantly higher risk of NACE compared with the single-vessel subgroup (12.5% versus 6.7%, HR IPTW:1.84, 95%CI:1.35-2.51, P<0.001). No significant interaction was observed between vessel status (multivessel or single-vessel) and treatment allocation with respect to NACE (Pinteraction=0.542). In the multivessel subgroup, NACE occurred in 44/368 (12.1%) and 45/352 (12.9%) in the stepwise de-escalation and standard DAPT groups (HR IPTW:0.95, 95%CI:0.62-1.75, P=0.818), respectively. In the single-vessel subgroup, NACE occurred in 43/607 (7.1%) and 39/621 (6.3%) in the stepwise de-escalation and standard groups (HR IPTW:1.12, 95%CI:0.72-1.70, P=0.611), respectively. For the prespecified hierarchical secondary endpoint, win ratio analyses yielded more wins for stepwise de-escalation in both subgroups. CONCLUSIONS Among patients with ACS undergoing DCB-only angioplasty, those with multivessel disease were associated with a higher risk of NACE than those with single-vessel disease. Stepwise DAPT de-escalation and standard DAPT exhibited similar risk-benefit profiles in both subgroups.
