Although alterations in myofibrillar ATPase as well as changes in myosin isozymes in the left ventricle due to myocardial infarction were modified by treatment with angiotensin-converting enzyme (enalapril) as well as an angiotensin antagonist (losartan), the effects of these interventions were not determined in the right ventricle [45]. Here, MYH14 is linked to myocardial infarction.
