The invention provides a method of treating diastolic dysfunction, e.g., diastolic dysfunction with preserved ejection fraction, in a subject. The method comprises administering to the subject in an amount effective to treat the diastolic dysfunction a cardiac metabolic modifier, as described herein. In some embodiments, the diastolic dysfunction is characterized by (i) a lack of increased late I Na in cardiomyocytes, (ii) an increase in myofilament calcium sensitivity, or (iii) a combination thereof. In some embodiments, the subject does not suffer from a cardiac injury or a structural heart disease, as described herein. Further provided are a method of treating heart failure with preserved ejection fraction in a subject, a method of treating acute decompensated heart failure, a method of modulating myofilament calcium sensitivity in a subject, and a method of treating a condition associated with or caused by increased myofilament calcium sensitivity. |
