Safety of Routine Invasive Versus Selective Invasive Therapy in Women with Non-ST-Elevation Acute Coronary Syndrome.

Area of Science:

• Cardiology
• Interventional Cardiology
• Clinical Trials

Background:

• Prior research indicates routine invasive management benefits men with non-ST-elevation acute coronary syndrome (NSTE-ACS).
• Data on routine invasive strategies in women with NSTE-ACS are less conclusive, with one study noting increased bleeding risk.
• This pilot randomized trial specifically evaluated the safety of routine versus selective invasive strategies in women.

Purpose of the Study:

• To compare the safety of routine invasive versus selective invasive strategies in women diagnosed with NSTE-ACS.
• To assess the primary outcome of major bleeding risk between the two management approaches.
• To evaluate secondary outcomes including death, myocardial infarction, stroke, and re-hospitalization within six months.

Main Methods:

• Women with NSTE-ACS and high-risk features were randomized to either routine or selective invasive management.
• The primary endpoint was the incidence of major bleeding.
• Secondary endpoints included a composite of all-cause death, myocardial infarction, stroke, or re-hospitalization for ACS within 6 months.

Main Results:

• Major bleeding risk was similar between the routine invasive (23 women) and selective invasive (17 women) groups (P=0.99).
• Sixty-eight percent of participants had elevated troponin T and/or creatinine kinase-MB.
• The composite secondary outcome occurred in 9% of the routine invasive group versus 18% in the selective invasive group at 6 months.

Conclusions:

• A routine invasive approach appears safe for managing women with NSTE-ACS.
• The study suggests a potential benefit of routine invasive therapy over selective invasive therapy in this population.
• Findings support the design of a larger, powered trial to definitively determine the optimal management strategy for women with NSTE-ACS.
