Key result
Elevated HATCH score predicts ~33% higher risk of AF after CABG.
Why the study?
Does the preoperative HATCH score predict atrial fibrillation after isolated coronary artery bypass graft surgery?
Cohort (n=369)
Does the preoperative HATCH score predict atrial fibrillation after isolated coronary artery bypass graft surgery?
Odds Ratio: 1.334 (95% CI 1.022–1.741)
p-value: p=0.034
A preoperative HATCH score >1 is an independent predictor of postoperative atrial fibrillation in patients undergoing isolated CABG surgery.
HATCH score may identify higher AF risk after CABG; leaves open whether score-guided prophylaxis improves outcomes.
The aim of this study was to investigate the association between HATCH score and atrial fibrillation (AF) after coronary artery bypass graft (CABG) surgery. 369 patients (103 patients with AF and 266 patients without AF) undergoing isolated CABG surgery were analyzed. Complete medical records were retrospectively collected to investigate HATCH score. The median age of patients with AF was significantly higher than the median age of non-AF group (60.8±10.0 years vs 67.8±9.5 years, P<0.001). HATCH score was significantly higher in patients who developed AF after CABG surgery than the non-AF group (P=0.017). Multivariate logistic regression analysis showed that HATCH score (OR 1.334; 95% CI 1.022 to 1.741, P=0.034) was an independent predictor of AF after CABG surgery. Receiver operating characteristic curve analysis showed that the cut-off point of HATCH score related to predict AF was >1 (two or more), with a sensitivity of 42% and specificity of 70%. Patients with elevated preoperative HATCH score may have higher risk for AF after CABG surgery.

Selvi et al. (2017) conducted a cohort in Atrial fibrillation after CABG surgery (n=369). HATCH score vs. Lower HATCH score was evaluated on Atrial fibrillation after CABG surgery (OR 1.334, 95% CI 1.022 to 1.741, p=0.034). An elevated HATCH score was an independent predictor of atrial fibrillation after CABG surgery (OR 1.334; 95% CI 1.022 to 1.741; P=0.034).
