- The main function of the myocardium is to facilitate the contraction and relaxation of the heart walls in order to receive and pump the blood into the systemic circulation. In addition, the myocardial cells provide a scaffold for heart chambers and conduct electrical stimuli.

Nov 7, 2024 · The primary function of the myocardium is to generate the force required for the heart to contract and pump blood. The myocardium consists of specialized muscle cells, known as cardiomyocytes, which contract in a coordinated manner.

Dilated cardiomyopathy causes the cardiac muscle tissue of the left ventricle to stretch and the heart’s chambers to dilate.
Hypertrophic cardiomyopathy (HCM) is a genetic condition in which the cardiomyocytes are not arranged in a coordinated fashion and are instead disorganized. HCM can interrupt blood flow out of the ventricles, cause arrhythmias (abnormal electrical rhythms), or lead to congestive heart failure.
Restrictive cardiomyopathy (RCM) refers to when the walls of the ventricles become stiff. When this happens, the ventricles cannot relax enough to fill with an adequate amount of blood.
This rare form of cardiomyopathy causes fatty infiltration in cardiac muscle tissue in the right ventricle.
Transthyretin amyloid cardiomyopathy (ATTR-CM) develops when amyloid proteins collect and form deposits in the walls of the left ventricle. The amyloid deposits cause the ventricle’s walls to stiffen, which prevents the ventricle from filling with blood and reduces its ability to pump blood out of the heart. This is a form of RCM.
Jun 22, 2024 · The myocardium is responsible for the contractile function of the cardiac pump. Composed of cardiomyocytes, the heart muscle has distinctive cellular and physiological features, allowing it to generate force to maintain adequate tissue and organ perfusion throughout the body.

Jul 30, 2023 · Cardiac muscle also called the myocardium, is one of three major categories of muscles found within the human body, along with smooth muscle and skeletal muscle. Cardiac muscle, like skeletal muscle, is made up of sarcomeres that allow for contractility.

Nov 3, 2023 · The myocardium is functionally the main constituent of the heart and the thickest layer of all three heart layers. It is a muscle layer that enables heart contractions. Histologically, the myocardium is comprised of cardiomyocytes .
Jun 16, 2022 · Myocardium: This is the muscle layer of the heart responsible for the pumping action of the heart and occupies 95% of the cardiomyocytes mass and is the thickest layer in the heart wall. The thickness of the myocardial layer is dependant on the pressure which is present in each chamber.
