The children/adolescents/young adults who participated in the study all carried at least one gene associated with HCM, and were members of families with strong histories of HCM. None of the 38 young people had clinical manifestations of HCM at the beginning of the study period, while 4 went on to develop HCM by the end of the study. In collecting the data analyzed in the study, the test results of the 4 individuals with HCM were compared to the 34 individuals that did not have HCM at the end of the study.
The factors associated with the development of overt HCM, as identified by the researchers, were: abnormal left ventricular relaxation and higher ejection fraction, EKG changes, longer mitral valve leaflets, higher NT-proBNP concentrations and troponin values.
In the conclusion, the authors acknowledged the need for further research and investigation in order to better understand the natural course and evolution of the disease.
