Cardiac muscle is a muscle tissue composed of cardiac muscle cells. The broad definition of cardiac myocytes includes the specially differentiated cardiac myocytes that make up the sinoatrial node, intraatrial bundle, atrioventricular junction, atrioventricular bundle (i.e., Heath bundle), and Purkinje fibers, as well as the general working cells of the atrial and ventricular muscles. The first five species comprise the pacing and conduction system and contain few or no myogenic fibers, so none of them has a contractile function; however, they are autoregulatory and conductive and are the functional basis for the autoregulatory activity of the heart; the latter two species are contractile and are the functional basis for the diastolic activity of the heart. Dystrophy of the myocardial tissue is often seen in cardiomyopathies, etc.
Prevention and care of myocardial dystrophy
1. Quit smoking
Even if the nicotine and carbon monoxide content is low, smoking can be harmful to the respiratory organs and coronary arteries.
2. Quit eating foods with high cholesterol
because high cholesterol in the blood will lead to atherosclerosis and myocardial infarction.
3, quit high blood pressure
Because high blood pressure will increase the burden on the heart and lead to the risk of heart disease.
4. Quit obesity
Because obesity can lead to high blood pressure and increase the content of cholesterol in the blood.
5. Quit being sedentary
Sedentary and do not participate in physical exercise, the heart has a hundred harm but not a benefit.
6, quit eating food containing too much sugar
High blood sugar will induce diabetes and endanger the heart.
7, abstain from excessive emotional excitement
Because it will disrupt the balance of human organ function and lead to heart disease.
8, quit drinking too much alcohol
Regular excessive drinking will cause changes in heart rhythm, which will eventually lead to serious cardiovascular disease.
9, quit living irregularly, disorderly living
Long-term, will cause the human organ function disorder, thus increasing the risk of heart disease.
10.Stop being negligent and careless
If you find signs of high blood pressure and high cholesterol, you should consult a doctor and take medication in time, especially if you have a genetic history of heart disease, you should not take it lightly, because delaying treatment will often cause irreversible consequences.
