Prinzmetal Angina (synonyms: vasospastic angina, variant angina) in accordance with the definition of, it is caused by coronary artery spasm which occurs during sleep at night, between midnight and early morning and manifested with ST segment elevation on the ECG.
Frequent «attachment» to the attacks of a certain period of the sleep period, gives you the opportunity to use chronomedical approaching the treatment of patients suffering from it, as demonstrated by our observation.
On the other hand, for adulthood comorbidity is characteristic, and Prinzmetal is no exception, which we wanted to show, studying the clinical case.
KEY WORDS: prinzmetal angina, vasospasm, ST segment elevation, chronotropic effects, dysregulation

Стенокардія Принцметала (синоніми: вазоспастична стенокардія, варіантна стенокардія)
викликається спазмом коронарної артерії, виникає вночі під час сну, у проміжку між серединою ночі і рано вранці та проявляється підйомом сегмента ST на ЕКГ.
Часта «прихильність» нападів до певного проміжку періоду сну дає можливість використовувати у лікуванні пацієнтів хрономедичний підхід, що демонструється нашим спостереженням.
З іншого боку, для дорослого віку характерною є коморбідність, і стенокардія Принцметала не є винятком , що ми також показали , розглядаючи клінічний випадок.

In 03:25-03:29 registered episode of ST elevation by 3 mm, accompanied by the development of AV block of the I stage (maximum PQ 288 ms) in the future with the addition of AV block II stage (Mobitz 2). Episode coincided with an attack in the night, noted in the patient diary.
2nd. Holter ECG monitoring (17.10.12): Against the backdrop of the main sinus rhythm recorded: average heart rate during the day 73 beats/min, at night 61 beats/min, maximum heart rate 109 beats / min at 06:55, minimum heart rate 46 beats / min at 01 41. Circadian index - 1,19; episode of ST segment elevation greater than 2 mm in the night between 1:381:44 and 3:21-3:26. In the period following ischemia detected arrhythmias. Singles premature beats (5 in total) on the background of bradycardia (1 episode). Sinus tachycardia, heart rate 104 beats/min (1 episode).

At neurology: bilateral muscle-tonic
cervico-brachial neuralgia, dorsalgia due to degenerative disc disease, relapsing course, the stage of the protracted deterioration, severe pain.
Consultation of gynecologist: chronic leftsided salpangitis in remission.
CLINICAL DIAGNOSIS
Underlying disease: coronary artery disease. Vasospastic angina. Coronary atherosclerosis (CVG from 19.10.12). Hyperlipoproteinemia type 2b according to Fredrickson’s criteria. Transient AV block I stage, II stage (Mo-
bitz 2). Single supraventricular extrasystoles. Arterial hypertension stage II, 2 degree. Hypertensive heart. Risk 3. 1st stage of heart failure, 1st functional class with preserved systolic function.
Comorbidities: COLD. Obesity I degree. Chronic left-sided adnexitis in remission. Osteochondrosis of the cervical-thoracic scoliosis of the thoracic spine, functional failure of joints 0. Bilateral muscular-tonic cervico-brachial neuralgia, dorsalgia recrudescence.
RECOMMENDED TREATMENT
Lifestyle modification
Smoking cessation. Reduction in body weight (diet restriction of animal fats, carbohydrates, salt).Physical activity (therapeutic exercises, jogging, swimming). In the period of remission of osteochondrosis - massage cervical-thoracic spine.
Medication:
• Amlodipine 10 mg at bedtime,
• Nitroglycerin (1tab) under the tongue for relief of pain attack (allowed up to 5 tablets for 5 minutes),
• Atorvastatin 10 mg per day,
• Enalapril maleate 10 mg per day,
• Cardiomagnyl 75 mg per day during the meal.
Planned hospitalization 23.04.13: satisfactory condition. Blood pressure 130 /90 mm Hg, pulse 68 beats/min. Slowing to 2-4 attacks of heart pain per month, reducing the intensity of pain. ECG showed sinus rhythm, regular, HR 73 beats/min deviation of electrical axis of heart to the left. Echocardiography: heart cavity is not an extension, moderate thickening of the walls of the left ventricle (Thickness of posterior wall of left ventricle 11.26 mm), Akinesia zones not found, valves are intact. EF = 79 %. Holter ECG monitoring (23.04.13): circadian index of 1.17. Found: 6 tachycardias, the total duration of 8 minutes 40 second. Single supraventricular arrhythmias. Episodes of ST elevation not detected. Noted a significant positive trend.
Prinzmetal angina usually occurs in adulthood, usually at night, often in women [1], which corresponds to our observation. Present atherosclerotic plaques exceed 30 % of the lumen of the coronary arteries and do not provoke attacks during the day, not counting the very first episode, which, after a demonstration was not repeated. Of the risk
factors spasm, including circadian dysregulation, physical and mental distress, the medication (ephedrine, ergonovine, bromocriptine, 5-fluorouracil, propofol), smoking, cocaine use, our patient had two -circadian dysregulation (circadian index 1, 19), and smoking. Characteristic of the development of attack rhythm disturbances in the form of transient atrioventricular and intraventricular blocks, frequent ventricular arrhythmia of high grade, paroxysmal tachycardia and ventricular fibrillation [2] in our case were atrioventricular block of 1st and 2nd degree. Isolated supraventricular extrasystoles and paroxysmal sinus tachycardia. The European Society of Cardiology recommended methods of diagnosis [3] (ECG during an attack , coronary angiography for evaluation of coronary vessels, intracoronary provocative tests for the identification of coronary spasm , Holter ECG monitoring to detect shifts of ST segment), we used coronary angiography and Holter ECG monitoring .
REFERENCES
Also, following the recommendations of the European Society of Cardiology [3], we have assigned therapy with calcium antagonists and nitrates.
CONCLUSION
Clinical case is interesting primarily by chronotherapeutic approach in the treatment, when the occurrence of spasms around the same time of night sleep (about 3-3:30 am) allowed to assign amlodipine once a day at bedtime with significant positive dynamics in the quality of life and decrease in the frequency of attacks to 2-4 per month with a decrease in pain intensity.
It is important to pay attention to comorbidity with other diseases in the case of Prinzmetal angina (atherosclerosis, obesity, hypertension, low back pain, circadian disorders) that might provoke attacks and aggravate its course and intervention which contributed to a better clinical outcome.
