The Cellular Structure of HCM-affected Hearts
Hypertrophic Cardiomyopathy (HCM) is a complex cardiac disorder characterized by significant changes in the cellular structure of the heart. Understanding these structural alterations is crucial for comprehending the development and progression of HCM.
Cardiac Muscle Changes in HCM
In HCM-affected hearts, various modifications occur in the structure of cardiac muscle cells. These changes not only involve alterations in cell size and shape but also impact the organization and composition of the cardiac tissue.
One of the primary cellular changes observed in HCM is myocardial hypertrophy, which refers to the enlargement of cardiac muscle cells. This hypertrophy can result from an increase in the number of myofibrils and the accumulation of intracellular proteins. As a consequence, the cardiac muscle cells become larger and appear disorganized in their arrangement.
Additionally, the sarcomeres, the basic contractile units of cardiac muscle, undergo changes in HCM. The sarcomeres become disarrayed, leading to an irregular alignment of the contractile proteins. This disruption in the organization of sarcomeres contributes to the impaired contractility of the cardiac muscle in individuals with HCM.
Furthermore, HCM is associated with fibrosis, a process involving the deposition of excessive connective tissue in the myocardium. The presence of fibrotic tissue disrupts the normal architecture of the cardiac muscle and impairs its function. Fibrosis can stiffen the myocardium, impair coronary blood flow, and interrupt the electrical conduction system of the heart, leading to arrhythmias.
A Visual Representation of Cellular Changes in HCM
To provide a visual representation of the cellular changes observed in HCM-affected hearts, let’s examine the following table:
| Cellular Changes | Implications |
