What are the Cellular Mechanisms Behind Myocardial Stiffness?
Several cellular mechanisms contribute to myocardial stiffness:
Fibrosis: The excessive formation of fibrous connective tissue. Inflammation: Chronic inflammation can lead to ECM remodeling and increased stiffness. Oxidative Stress: Damage caused by reactive oxygen species (ROS) can impair cellular function and promote fibrosis. Calcium Handling: Abnormalities in calcium homeostasis can affect cardiomyocyte contraction and relaxation, influencing stiffness.
