The heart ages through a series of structural and functional changes. These changes impact its ability to pump blood efficiently.
Understanding the Aging Heart
As we age, the heart undergoes several changes that can affect its function. It is important to understand these changes to better manage heart health.
Key Changes in the Aging Heart:
-
Lipofuscin Deposits: The heart accumulates "aging pigment," known as lipofuscin. This is a fatty brown pigment that accumulates within cells. (Reference)
-
Muscle Degeneration: Heart muscle cells degenerate slightly over time. This is a natural part of the aging process. (Reference)
-
Valve Thickening and Stiffening: The heart valves, which control blood flow direction, thicken and become stiffer. This stiffness can lead to heart murmurs. (Reference)
Impact on Heart Function:
These changes lead to:
- Reduced ability of the heart to pump blood effectively.
- Increased risk of heart murmurs due to valve stiffness.
Summary Table: Aging Heart Changes
| Change | Description | Impact |
|---|---|---|
| Lipofuscin Deposits | Accumulation of "aging pigment" in the heart cells. | Gradual change in the cell structure and function. |
| Muscle Degeneration | Slight degeneration of heart muscle cells. | Reduces strength and efficiency of heart contractions. |
| Valve Thickening/Stiffening | Heart valves thicken and lose flexibility. | Impaired blood flow and potential heart murmurs. |
