Analysis of risk factors for major adverse cardiac events caused by myocardial bridge

  AIM  To investigate the risk factors for major adverse cardiac events (MACE) caused by myocardial bridge (MB).

  METHODS  Clinical data of 43 MB patients in left axis deviation (LAD) were collected and related risk factors for MACE caused by MB were investigated.

  RESULTS  A total of 43 patients were divided into two groups according to whether they had the incidence of MACE: MACE group (23 patients) and non-MACE group (23 patients). The patients' baseline information and MB stenosis, length and thickness were compared between the two groups. The results showed that smoking, drinking, 2-hour postprandial blood glucose, resting heart rate, and MB stenosis and thickness were statistically significant between the two groups (P<0.05). Logistic regression analysis showed that smoking, drinking and MB stenosis were suspected risk factors for MACE. The OR value were 11.085, 10.095 and 5.385, respectively (P<0.05).

  CONCLUSION  MB can cause MACE and smoking, drinking, 2-hour postprandial blood glucose, resting heart rate, and MB stenosis and thickness of are suspected risk factors for MACE in MB patients.
