HATCH score for progression from paroxysmal to persistent AF

HATCH score for progression from paroxysmal to persistent AF HATCH score for prediction of progression from paroxysmal to persistent atrial fibrillation (AF) checks the following: heart failure, age, previous transient ischemic attack or stroke, chronic obstructive pulmonary disease, and hypertension [1]. For the analysis, the authors used over 1200 patients with paroxysmal AF who participated in Euro Heart Survey on AF. Those who had progression of AF after one year of follow up were noted. The components and weightage given in HATCH score were as follows: Hypertension: 1 Age 75 years or more: 1 Transient ischemic attack or stroke: 2 Chronic obstructive pulmonary disease: 1 Heart failure: 2 In their study 15% had progression of AF. It was noted that 50% of those with a score more than 5 progressed to persistent AF while only 6% of those with score of zero progressed. Those with progression of AF had more hospitalizations. They also had more major cardiovascular events. Chen K et al [2] used the HATCH score to predict the occurrence of new onset AF after catheter ablation of typical atrial flutter. Of the over two hundred patients in their study 39% experienced at least one episode of over a follow up period of 29.1 ± 18.3 months. Using a cutoff score of 2, the group could be stratified into high risk group with 69% occurrence of AF vs a lower risk group with 27% occurrence of AF (P < 0.001).
