Myocardial insufficiency is a manifestation of heart disease.
The most common causes of insufficient blood supply to the myocardium include coronary heart disease and abnormal oxygen-carrying function of the blood.
1. Coronary heart disease: coronary arteries are responsible for blood supply to the heart muscle. When atherosclerosis occurs in the coronary arteries, hardened plaques are produced locally on the inner wall of the blood vessels, resulting in narrowing of the lumen. The blood flow through the blood vessels is not smooth, and even serious cases will be blocked, resulting in insufficient blood supply to the heart muscle.
2. Abnormal oxygen-carrying function of blood: Red blood cells in the blood carry oxygen and transport it to the heart to supply oxygen to the heart muscle. If the function of red blood cells is abnormal or oxygen is insufficient, it will also lead to the symptoms of insufficient blood supply to the heart muscle, which is commonly seen in anemia and lung function abnormality.
When myocardial hypoperfusion occurs, the patient has a dull or tight pain in the retrosternal or precordial area, and there is a discharge to the left shoulder and left upper arm. Myocardial insufficiency can be life-threatening.
If myocardial insufficiency is suspected, it should be treated promptly and actively.
