Insights
Predicting postoperative atrial fibrillation (PoAF) after coronary artery bypass graft (CABG) surgery is crucial. The HATCH score and waist-to-height ratio (WHR) are effective predictors, aiding in early risk identification and management.
Area of Science:
- Cardiology
- Cardiac Surgery
- Predictive Analytics
Background:
- Postoperative atrial fibrillation (PoAF) is a common complication after coronary artery bypass graft (CABG) surgery.
- PoAF increases risks of cerebrovascular events, prolongs hospital stays, and elevates healthcare costs.
Purpose of the Study:
- To evaluate the predictive capability of the HATCH score and waist-to-height ratio (WHR) for PoAF development post-CABG.
- To identify key preoperative indicators for PoAF risk stratification.
Main Methods:
- Prospective study of 255 patients undergoing isolated CABG with cardiopulmonary bypass.
- Collection of preoperative demographic, laboratory, and operative data.
- Analysis of HATCH score and WHR in relation to PoAF incidence.
Main Results:
- PoAF occurred in 59 patients (23.1%).
- Higher rates of chronic obstructive pulmonary disease, previous percutaneous coronary interventions, WHR, and HATCH scores were observed in patients who developed PoAF.
- Multivariate analysis confirmed WHR (OR: 1.068) and HATCH score (OR: 2.590) as independent predictors of PoAF.
Conclusions:
- Preoperative calculation of WHR and HATCH score can effectively predict PoAF after CABG.
- These simple metrics can aid clinicians in identifying high-risk patients for targeted interventions.
Objectives:
Postoperative atrial fibrillation (PoAF), an important clinical condition that can occur after coronary artery bypass graft (CABG) operations, may bring about cerebrovascular risks, prolong hospital stay and increase treatment costs. In this prospective study, we aimed to investigate the predictive value of HATCH score and waist/height ratio (WHR) values in revealing the development of PoAF after CABG operations.
Methods:
Patients who underwent isolated CABG surgery with cardiopulmonary bypass between May 2019 and November 2019 were prospectively included in the study. Preoperative demographic characteristics, laboratory parameters, and operative parameters of the patients were recorded prospectively.
Results:
A total of 255 patients were included in the study. Those who did not develop PoAF were included in Group 1 (N = 196, mean age = 58.9 ± 9.4 years), and those who did were included in Group 2 (n = 59, mean age = 61.1 ± 12 years). There were no statistically significant differences between the two groups in terms of age, gender, presence of hypertension and hyperlipidemia. Rates of chronic obstructive pulmonary disease and previous percutaneous coronary interventions, waist circumference, waist to height ratio and HATCH score values were significantly higher in Group 2 compared to Group 1 ( p values: 0.019, 0.034, 0.001, <0.001, <0.001, respectively). In multivariate analysis, WHR (Odds ratio: 1.068, Confidence interval: 1.032-1.105, p < 0.001) and HATCH score (Odds ratio: 2.590, Confidence interval: 1.850-3.625, p < 0.001) were independent predictors of PoAF.
Conclusions:
With this current prospective study, we showed that calculating WHR and HATCH score in the preoperative period can help us predict PoAF.
