The Association Between Myocardial Bridging and Atrial Fibrillation in Patients With Obstructive Hypertrophic Cardiomyopathy
The Association Between Myocardial Bridging and Atrial Fibrillation in Patients With Obstructive Hypertrophic Cardiomyopathy
This study investigated the impact of myocardial bridging (MB) and its characteristics on preoperative atrial fibrillation and survival in patients with obstructive hypertrophic cardiomyopathy (oHCM). We recruited 968 consecutive patients with oHCM who underwent myectomy at our institution between January 2015 and December 2019, including 144 patients with MB and 824 patients without MB. All patients received angiography before surgery. The diagnosis of preoperative atrial fibrillation was based on 12-lead electrocardiography, 24-hour Holter electrocardiography, or in-hospital electrocardiogram monitoring, which was extracted from patients' medical records. Surgical details and follow-up data were also collected.
Inclusion Criteria:I(i) age ≥ 18 years and (ii) diagnosis of oHCM based on clinical and echocardiographic evaluation.

Exclusion Criteria: (i) a history of heart surgery (ii) Patients who had coronary atherosclerosis or myocardial infraction; (iii) Patients who had no angiography records.
