The role of HATCH score in predicting the success rate of sinus rhythm following electrical cardioversion of atrial fibrillation

Abstract

A b s t r a c t Background:The HATCH score predicts the development of persistent and permanent atrial fibrillation (AF) one year after spontaneous or pharmacological conversion to sinus rhythm in patients with AF. However, it remains unknown whether HATCH score predicts short-term success of the procedure at early stages for patients who have undergone electrical cardioversion (EC) for AF. Aim:The present study evaluated whether HATCH score predicts short-term success of EC in patients with AF. Methods:The study included patients aged 18 years and over, who had undergone EC due to AF lasting less than 12 months, between December 2011 and October 2013. HATCH score was calculated for all patients. The acronym HATCH stands for Hypertension, Age (above 75 years), Transient ischaemic attack or stroke, Chronic obstructive pulmonary disease, and Heart failure. This scoring system awards two points for heart failure and transient ischaemic attack or stroke and one point for the remaining items. Results:The study included 227 patients and short-term EC was successful in 163 of the cases. The mean HATCH scores of the patients who had undergone successful or unsuccessful EC were 1.3 ± 1.4 and 2.9 ± 1.4, respectively (p < 0.001). The area of the HATCH score under the curve in receiver operating characteristics analysis was (AUC) 0.792 (95% CI 0.727-0.857, p < 0.001). A HATCH score of two and above yielded 77% sensitivity, 62% specificity, 56% positive predictive value, and 87% negative predictive value in predicting unsuccessful cardioversion.Conclusions: HATCH score is useful in predicting short-term success of EC at early stages for patients with AF, for whom the use of a rhythm-control strategy is planned.

CHA2DS2VASc score predicts unsuccessful electrical cardioversion in patients with persistent atrial fibrillation

“…Similarly to our study, Emren et al in the analysis of 227 patients reported that the CHA 2 DS 2 VASc score in patients who had unsuccessful cardioversion was higher compared to patients who had successful CV (3.2 vs 1.7; P = 0.001) …”

The Relationship between the HATCH Score, Neutrophil to Lymphocyte Ratio and Postoperative Atrial Fibrillation After Off-Pump Coronary Artery Bypass Graft Surgery

“…In their study conducted on 284 patients, Emren et al detected PoAF in 25% of the patients and reported that the HATCH score significantly was higher in the PoAF group (P < .001). After Roc analysis, a HATCH score of 2 or more was found to predict PoAF with 72% sensitivity and 75% specificity [Emren 2016]. Selvi et al reported a PoAF ratio of 28% in 369 patients.…”

Investigation of the Effect of HATCH Score and Coronary Artery Disease Complexity on Atrial Fibrillation after On-Pump Coronary Artery Bypass Graft Surgery

“…They found that increasing the HATCH score from 0 to 7 increased the incidence of AF from 0.8 to 57.3 per 1,000 patient-years [21]. Another study by Emren et al [22] investigated the importance of the HATCH score in the return of sinus rhythm after electrical cardioversion in 227 patients. The HATCH scoring system was found to indicate early clinical success.…”
