Insights
Continuous multi-antithrombotic therapy (AT) is safe for cardiac implantable electronic device (CIED) procedures. However, patients with high HAS-BLED scores or valvular heart disease need careful monitoring for pocket hematomas.
Area of Science:
- Cardiology
- Medical Devices
- Thrombosis Management
Background:
- Previous studies indicate safety of single antithrombotic therapies during CIED implantations.
- The safety profile of continuous multi-antithrombotic therapy (AT) in CIED interventions remains unclear.
Purpose of the Study:
- To evaluate the safety of continuous multi-antithrombotic therapy (AT) during cardiac implantable electronic device (CIED) implantations.
- To assess the incidence of perioperative complications, specifically clinically significant pocket hematomas (PH) and thromboembolism.
Main Methods:
- A prospective study involving 300 patients undergoing CIED implantations.
- Patients were categorized into six groups based on antithrombotic therapy: No-AT, oral anticoagulant therapy (OAT), single antiplatelet therapy (SAPT), OAT + SAPT, dual antiplatelet therapy (DAPT), and triple AT (TAT).
- Clinically significant PH was defined as requiring surgical intervention, prolonged hospitalization, AT interruption, or blood transfusion.
Main Results:
- No significant difference in the occurrence of clinically significant PH or thromboembolism was observed among the six AT groups (p=0.145 and p=0.795, respectively).
- High HAS-BLED score (p=0.014) and valvular heart disease (VHD) (p=0.015) were significantly associated with an increased risk of clinically significant PH.
- Continuous multi-AT regimens were generally tolerated during CIED procedures.
Conclusions:
- Continuous multi-antithrombotic therapy (AT) appears to be a safe option for patients undergoing cardiac implantable electronic device (CIED) procedures.
- Careful attention and risk stratification are necessary for patients with a high HAS-BLED score or valvular heart disease undergoing CIED implantations due to increased risk of pocket hematomas.
Abstract:
Previous studies showed that continuous anticoagulation or single antiplatelet therapy during implantations of cardiac implantable electronic devices (CIED) was relatively safe. However, the safety of continuous multi antithrombotic therapy (AT) in patients undergoing CIED interventions has not been clearly defined. We sought to evaluate the safety of this therapy during CIED implantations. A total of 300 consecutive patients (mean 69 years old, 171 males) with CIED implantations were enrolled in this study. The patients were divided into 6 groups [No-AT, oral anticoagulant therapy (OAT), single antiplatelet therapy (SAPT), OAT and SAPT, dual antiplatelet therapy (DAPT), triple AT (TAT)], and the perioperative complications were evaluated. Clinically significant pocket hematomas (PH) were defined as PH needing surgical intervention, prolonged hospitalizations, interruption of AT, or blood product transfusions. There were 129, 89, 49, 20, 10, and 3 patients in No-AT, OAT, SAPT, OAT + SAPT, DAPT, and TAT groups, respectively. The occurrence of clinically significant PH and thromboembolism did not differ among 6 groups (p = 0.145 and p = 0.795, respectively). However, high HAS-BLED score and valvular heart disease (VHD) were associated with clinically significant PH (p = 0.014 and p = 0.015, respectively). Continuous multi AT may be tolerated, but patients with high HAS-BLED score or VHD would require a careful attention during CIED implantations.
