NCT04112511

Brief Summary

The purpose of the study is to investigate the potential correlations of global longitudinal strain and peak left atrial strain, measured by speckle tracking echocardiography with the severity of hypertrophic cardiomyopathy and the risk for arrhythmias. Specifically the investigational questions are:

  1. 1.Is there a correlation between myocardial deformation parameters of the left heart chambers with other important ultrasound parameters (eg maximal wall thickness, presence of subaortic obstruction, etc.) in patients with hypertrophic cardiomyopathy?
  2. 2.Is there a correlation between myocardial deformation parameters of the left heart chambers and the symptomatology or functional capacity of patients with hypertrophic cardiomyopathy?
  3. 3.Is there a correlation between the myocardial deformation parameters of the left heart chambers and the exercise capacity, as evidenced by the cardiopulmonary exercise test, in patients with hypertrophic cardiomyopathy?
  4. 4.Is there a correlation between myocardial deformation parameters of the left heart chambers with the risk of ventricular or supraventricular arrhythmias in patients with hypertrophic cardiomyopathy?
  5. 5.Is there a correlation between myocardial deformation parameters of the left heart chambers and risk factors for sudden death?
