PACE DRAP: a simple score for predicting significant bleeding complications after cardiac implantable electronic...

Area of Science:

• Cardiology
• Medical Informatics
• Surgical Risk Assessment

Background:

• Significant bleeding complications (SBCs) are a risk after cardiac implantable electronic device (CIED) surgery.
• Currently, no validated risk score exists to predict SBCs in this patient population.

Purpose of the Study:

• To develop and validate a novel scoring system for predicting SBCs post-CIED surgery.
• To identify key predictors of SBCs in patients undergoing CIED procedures.

Main Methods:

• Multivariable logistic regression analysis was used to identify independent predictors of SBCs.
• A risk score (PACE DRAP) was developed based on weighted predictors and their regression coefficients.
• The predictive performance of the PACE DRAP score was evaluated using sensitivity, specificity, and area under the curve (AUC).

Main Results:

• The incidence of SBCs was 4.5%.
• Key predictors identified include advanced age (≥75 years), specific CIED procedures (CRT/ICD, upgrade), uncontrolled hypertension, valvular prosthesis, current malignancy, renal failure, and use of specific antiplatelet drugs (ticagrelor, clopidogrel).
• The PACE DRAP score demonstrated good predictive ability (AUC=0.95) with a cutoff of 6 points yielding 88.24% sensitivity and 87.23% specificity.

Conclusions:

• The PACE DRAP score is a valuable tool for identifying patients at high risk of SBCs after CIED surgery.
• This score can aid clinicians in risk stratification and potentially guide preventative strategies.
