(explination of previous answer)
epicardium - outer layer of the heart
myocardium - the mucle part, contains the perkinje fibers
endocardium - inner lining of the heart
The two types of true tissue found in cnidarians are the epidermis and the gastrodermis.
Cardiac muscle is found in the heart. The other two types of muscle are smooth and striated (skeletal) muscle.Cardiac muscle, the third kind of muscle (the other two being skeletal and smooth muscle.
Cardiac Muscle is smooth but looks striated
there two different types of Heart disease

here the heart has muscular tissue.The muscles mainly involved are cardiac(smooth muscle) and involuntary.This is because they are not under our control.
Smooth muscles and cardiac muscles are controlled involuntarily - they are not under conscious control. Smooth muscles control functions such as digestion and blood vessel constriction, while cardiac muscles control the beating of the heart.
Two types of tissues that are largely replaced by scar tissue are cardiac muscle tissue and nervous tissue. In the heart, after a myocardial infarction (heart attack), damaged cardiac muscle is replaced by fibrous scar tissue, which does not contract or function like healthy muscle. Similarly, in the nervous system, injuries to neurons often result in scar tissue formation by glial cells, which inhibits regeneration and functional recovery.
An organ is a structure composed of two or more tissue types that work together to perform specific functions for the body. Examples of organs include the heart, lungs, and liver.
Plant tissue systems fall into one of two general types: meristematic tissue and permanent (or non-meristematic) tissue. Cells of the meristematic tissue are found in meristems, which are plant regions of continuous cell division and growth.
The first type of heart is the simple two chambered heart, which is found in fish. The second is the third chamber heart, which is found in amphibians and reptiles. Mammals and birds have four chambered hearts.
The main cell type found in nervous tissue is the neuron. Neurons are responsible for transmitting electrical signals within the nervous system and are specialized for communication through both electrical and chemical signals.
