the heart
the heart It is an involuntary muscle that distinguishes from the rest of the muscles as it makes the difference itself. It does not need an external stimuli. It is located in the middle of the chest area. It is tilted to the left. Blood is pumped through the blood vessels throughout the body. The blood is transferred to the oxidized blood and the waste is removed. Today, there are about 100,000 pulses, and the blood is pumped four to five times a minute, about 2,000 gallons a day.
The heart is made up of four chambers, the upper and the right, called the athenae, which receive the blood, the lower stones and the two ventricles that host the blood. The heart nourishes the coronary arteries that extend across the surface of the heart to supply oxygen. The nerve feeds it through a group of nerves through which it regulates the process of the pulse from contraction and expansion. The heart is surrounded by a membrane called the pericardium.
Heart and Stress
The muscle is one of the strangest muscles in the body, because it does not resemble the rest of the muscles in stress, as the muscle continues to contract and spread throughout the human life without fatigue or interruption, but in a few cases, if the human effort and high over-capacity for a long time, the muscle will work Faster than normal to the degree of capacity and capacity to absorb, to keep up with the requirements of the body of blood and oxygen perfusion, this muscle strain, and slow down a little, increasing the period of contraction than normal.
For the importance of the heart muscle, any imbalance in this muscle occurs severe pain in the chest area, and may extend to the shoulders, the human contraction and tightness force him to stop moving and doing what he was doing, but if he continued what he was doing, this may develop casual pain and turn To a real problem that permanently harms the heart, and the stress of this muscle turns into myocardial infarction.
If the person responds to these signs early and is fully rested, pain will gradually diminish until it fades within a maximum of three minutes. This condition is never considered serious if the appropriate rest is taken. It is an expression of increased pressure and stress on the muscle. If this condition is repeated more than once within a short period of time, the person should see the doctor as soon as possible.
Causes of heartache
There are several reasons for heart pain, but we will review some of these reasons:
- CHD : Blockage of blood vessels in the heart reduces the arrival of blood and oxygen to the heart muscle itself, and this causes pain called angina, which is a symptom of heart disease, and usually does not cause a permanent defect in the muscle, and this indicates the possibility of a heart attack in the future. This pain can extend to the hand, shoulder, palate, or even back, where the patient may feel the sensation of pressure or weight on the chest, and this angina is stimulated by stress, or excessive enthusiasm, or psychological pressure, and reduce or even hide the rest.
- Myocardial infarction : The continued lack of blood access to the heart muscle leads to the death of myocardial cells, and pain similar to pain angina pectoris, but the most severe pain is characterized by the infertility and is in the middle of the chest or leaning to the left and does not go with comfort, accompanied by severe pain sweating, or tightness of breath, A year in the flesh.
- Myocarditis In addition to chest pain, myocardial infarction is associated with fever, general fatigue, rapid heartbeat and breathing problems. Although there is no interruption in cardiomyopathy, heart attack symptoms may be similar to angina and infarction.
- Inflammation of the heart : Its symptoms are similar to those of angina, usually severe pain in the amount along the neck and shoulders, and worse with breathing, swallowing food, or lying on the back.
- Hypertensive myocardial infarction : A genetic disease that causes abnormal growth of the heart muscle to make it thicker, this affects negatively on the heart. Symptoms include chest pain, shortness of breath during stress, and over time, heart failure may occur when the muscle is overpowered, making it difficult to pump blood from the heart to the rest of the body. Chest pain is accompanied by other symptoms, such as: dizziness, fainting, and other symptoms of heart failure.
- Conjugation of mitral valve : A condition in which the coronary valve fails to close completely, and has a wide range of symptoms including chest pain, heart palpitations, and dizziness, and may not be accompanied by any symptoms, especially if the relaxation is simple.
- Coronary artery dissection : Caused by a combination of rare but fatal factors, the patient feels severe torn pain in the chest extends to the neck and back or even the abdomen.
There are other pains that may occur in the chest area resulting from increased tension and anxiety, where the body has convulsions in the muscles of the chest and shoulders, and similar to the symptoms of angina pectoris may raise the fears of the infected person, in addition to some diseases of the lung and diseases of the esophagus may resemble heart disease, You should pay close attention to the nature of the pain and its symptoms, and the symptoms associated with it to diagnose the condition correctly, and sometimes even doctors find it difficult to correctly diagnose the disease, should never underestimate chest pain, and see the doctor immediately if the pain does not disappear after several minutes.
