Pathophysiology of Dilated Cardiomyopathy
Understanding the pathophysiology of dilated cardiomyopathy (DCM) is critical for grasping how the disease progresses and the implications it holds for treatment. DCM involves the dilation of the heart chambers, primarily affecting the left ventricle. This dilation leads to a reduction in the heart’s ability to pump blood effectively, which can result in heart failure. The mechanisms underlying this condition reveal not just the structural changes in the heart muscle but also the cellular and molecular alterations that contribute to its development and progression.
Cellular and Molecular Mechanisms
At the cellular level, DCM is characterized by the hypertrophy and eventual degeneration of myocytes, the muscle cells of the heart. Various factors contribute to these changes, including genetic mutations, oxidative stress, and inflammation. For example, mutations in genes such as TTN can lead to structural abnormalities in contractile proteins, ultimately affecting the myocyte's function.
Additionally, a significant increase in reactive oxygen species (ROS) occurs, which contributes to oxidative stress. This stress can damage cellular components and impair signaling pathways critical for maintaining healthy cardiac function. Key signaling molecules such as calcium ions also play a role. Abnormal calcium handling can further impair contractility, leading to a vicious cycle of worsening heart function.
Key Points:
