Stenocardia is one of the forms of ischemic heart disease. The direct cause of the disease is atherosclerosis of the arteries of the heart, in which the lumen of the heart vessels narrowed by atherosclerotic plaques (deposits of cholesterol in the artery wall), and the heart receives insufficient blood, i.e. is in a state of starvation, which is accompanied by bouts of pain in the heart.
Symptoms of stenocardia
Stenocardia is manifested by seizures usually occur during physical activity. Less frequently they appear in connection with anxiety, can also be caused by output from a warm room into the cold air, Smoking, alcohol, rich food. In between bouts person usually nothing worries.
Attack stenocardia pressure is manifested by pain, which, as it burns and compresses the heart. Sometimes it is perceived as simply heaviness, squeezing, tightness or compression. Most often, patients with stenocardia describe the pain as a brick on his chest”. Man seeks as quickly as possible to stop the load, to stop, to sit, to breathe fresh air.
Typical location of pain behind the breastbone, but often it feels and to the left. Attacks can be accompanied by difficulty breathing, dizziness and fear, less frequently, nausea or vomiting.
After the cessation of stress attack resolves on its own within 2 to 5 minutes. The fastest effect of taking nitroglycerin tablets under the tongue. If the seizure lasts more than 10 minutes and the pain subsides, it is better to call an ambulance – it may cause serious damage to the heart.
Stenocardia can occur in different forms
Experts identify several forms of angina: stable angina, unstable angina and angina at rest and angina and more rare variant angina. Separately allocated first developed angina, which almost always requires hospitalization.
The most common form of angina. Attacks arise under load: usually during walking, running, work, but also the pain can cause emotional crass, cold, heat, overeating and other.
Angina peace called late-stage disease, when exercise is limited so that the pain can occur without it, that is alone. Variant angina due to several other reasons: instead of atherosclerotic plaques in its origin plays a major role spasm of the arteries of the heart. This form occurs in younger people.
Stable angina from time to time has the same symptoms. If the pain from the attack to the attack begins to grow, or acquires a new quality starts to give in the arm, jaw, etc), angina is considered to be progressive or unstable. Often these two forms can be harbingers of impending heart attack.
Because angina is one of the possible manifestations of CHD, all the complications of these diseases are common. Most often, over time, patients develop chronic heart failure, manifested by swelling of the feet and shortness of breath.
High blood pressure is not a complication, but an aggravating factor strokes, the higher the pressure, the harder the heart to push the blood through the vessels and the faster it wears out.
