What is the myocardium?

The myocardium is accurately defined as the muscular middle layer of the heart. This layer is essential because it is the thick, contractile tissue that allows the heart to pump blood effectively throughout the body. The myocardium consists of cardiac muscle cells that are responsible for the rhythmic contractions of the heart, enabling it to function as an efficient pump.

The strength and health of the myocardium are crucial for overall cardiovascular health, as any conditions affecting this layer, such as hypertrophy or ischemia, can lead to serious complications like heart failure or other cardiovascular diseases. Understanding the role of the myocardium helps in recognizing how various factors like exercise, diet, and disease can impact heart function.
