Spontaneous angina does not occur so often. She also called angiospastic, vasospastic, variant angina and Prinzmetal (on behalf of the American cardiologist for the first time highlighted its main features). The causes of spontaneous angina is not fully established yet.
What is happening in the patient's body
Variant angina is characterized by the fact that the attacks of chest pain are not related to the physical and psychological stress. Angina attack which develops usually at night, when the patient is sleeping.
A distinctive feature of this form of angina is that it develops in the background of a sharp spasm of large coronary (feeding the heart muscle - the myocardium) vessels. That is why it is called vasospastic or angiospastic. The attack time and within about 10 minutes after it can be seen on ECG changes typical of myocardial infarction. But unlike a true myocardial infarction these changes and then disappear.
Spontaneous angina can develop on the background of atherosclerosis, but more evidence of atherosclerotic changes in the coronary vessels are not. Until today, not exactly known causes of this form of angina. It is believed that patients with angina Prinzmetal
Prinzmetal angina - a rare disease with serious consequences
there is an increased sensitivity of endothelial cells (the inner lining of the wall) vessels to the action of biologically active substances produced in the body during metabolism and vasoconstrictor action. If there is a release of such substances into the blood, the response is not adequately strong spasm of the coronary arteries.
Spontaneous angina - symptoms
Vasospastic angina attacks appear alone at night or early morning. The patient wakes up from a severe pain in the chest radiating to the left arm and shoulder blade. The duration of a spontaneous attack of angina 2-5 minutes, after which it passes unnoticed.
Sharp pressing pain during an attack increases, reaches a peak and then gradually disappear. Often these attacks are accompanied by fear of death, weakness, dizziness, sweating, nausea. During the attack, the patient may even lose consciousness.
Besides attacks angiospastic (angina) pain, signs of angina
Symptoms of angina - chest discomfort
there may be so-called angina equivalents:
- feeling short of breath, difficulty breathing at the inhalation and exhalation; sometimes it is the only sign of shortness of breath angina attack
Angina - oxygen deficiency
;
- sudden weakness, dizziness, trembling of the limbs and body.
Attacks of Prinzmetal angina, nitroglycerin shoots well. Notify an attack is possible by means of a group of drugs, and calcium channel blockers such as nifedipine.

The current spontaneous angina may be complicated by cardiac arrhythmias, myocardial infarction, and in the long course - heart failure.

Spontaneous angina: diagnosis
In the absence of signs of atherosclerosis diagnosed spontaneous angina easy. Significant signs of the disease can be identified on the basis of ECG Holter monitoring - a method by which oversees the work of the heart during the day, followed by an analysis of the data.
With this method it is possible to identify any kind of cardiac arrhythmia, angina (such as pain and cash equivalents).
Spontaneous angina: treatment
Removed spontaneous angina attack nitroglycerin. If one tablet of nitroglycerin has not helped, 2-3 minutes to take the second pill. If the angina does not pass, you should call an ambulance, because there is a risk of myocardial infarction.
To prevent progression of the disease patients are encouraged to maintain a healthy lifestyle, including healthy eating stick
Healthy eating - do not limit yourself to eating
, Give up bad habits (smoking, alcohol abuse, and so on).
Medication - prescription drugs is the group of nitrates (eg, Nitrosorbid) and the group of calcium antagonists (nifedipine, verapamil, diltiazem) for the prevention of angina attacks. The doses of these drugs are chosen for individual patients.
In some cases, for the prevention of thrombosis rates prescribed aspirin in small doses.
Spontaneous angina - is a serious disease. Patients who suffer from it, must be under the constant supervision of a cardiologist.
