National Library of Medicine Hypertrophic cardiomyopathy (HCM) results from genetic mutations in the cardiac sarcomere gene, which in turn, codes for integral components of the contractile apparatus of the heart muscle. Your heart fails to push blood through the system adequately, or it fails to fill properly. Unlike patients with predominant heat exacerbation symptoms (Table), the groups showed no difference in family history of SCD or rate of ICD implantation No difference in rate of LVOT obstruction at rest or with provocation was noted between the 2 groups.

The presence of an LVOT gradient either at rest or with provocation was similar among all groups. 
Although no difference between patient groups was observed in resting or provoked LVOT, the gradient was tested at typical room temperature, and a gradient provoked by temperature fluctuations therefore may have been missed. Prior studies, however, did not specifically investigate temperature-related symptomatology.
From the initial planning meeting, the focus was on how to align the recommendations into a workflow that mirrors a patient evaluation including specific discussions on the management of obstructive versus nonobstructive HCM.
