Abstract
Vasospastic angina is extremely uncommon for adolescents to experience chest discomfort, which is defined by transitory ST segment elevation or depression and angina symptoms that occur while at rest. It may result in potentially fatal conditions like myocardial infarction, ventricular fibrillation, or even sudden cardiac arrest. To aim of this article is to report a very rare case of a 17-year-old male Afghan refugee who was diagnosed with vasospastic angina after presenting with chest pain, and after receiving calcium channel blocker and nitrates for medical therapy, there were no angina attacks. Our case underlines the value of a thorough evaluation of adolescent's chest pain, the need to diagnose based on the symptoms, and the necessity of performing coronary angiography to rule out coronary causes when there is a high suspicion to a cardiac cause.

Abstract
Variant angina is caused by coronary artery spasm (CAS) with ST-segment elevation. We herein report a case of recurrent CAS during 2 operations in the same patient. An 80-year-old woman was scheduled to undergo tracheostomy, submandibular dissection, left partial maxillectomy, and coronoidectomy. We administered ephedrine and phenylephrine to manage hypotension during general anesthesia. Immediately after the administration of these drugs, the ST segment elevated. We decided to cease the operation and transport the patient to the department of cardiology. Computed tomography angiography revealed pneumomediastinum. The cardiologists considered that the electrocardiography findings had changed secondary to pneumomediastinum. About 6 weeks later, a second operation was scheduled. We administered ephedrine and phenylephrine to manage hypotension during general anesthesia. Immediately after the administration of these drugs, ST-segment elevation occurred. We discontinued use of these drugs, and the ST-segment elevation did not recur. We considered that the cause of the ST-segment elevation was vasopressor-induced CAS because the vasopressors were administered immediately before the occurrence of CAS. Vasopressors such as ephedrine or phenylephrine are frequently used to manage hypotension during general anesthesia. Therefore, anesthesiologists should consider the occurrence of CAS before using vasopressors and know how to manage CAS well.

Abstract
BACKGROUND Statin therapy reduces the risk of cardiovascular events in patients with obstructive coronary artery disease. The aim of the present study was to determine the effects of statins on the prognosis of patients with coronary vasospastic angina (VSA) free of significant atherosclerotic stenosis. METHODS AND RESULTS After exclusion of 475 from 1877 consecutive patients who underwent an acetylcholine-provocation test between January 1991 and December 2010, data of 640 VSA patients without significant organic stenosis of the remaining 1402 were analyzed retrospectively. Propensity score matching was performed to reduce the effect of treatment-selection bias and possible confounders. The primary endpoint was major adverse cardiac events (MACE), including cardiac death, nonfatal myocardial infarction, and unstable angina. Among the study population, dyslipidemia on admission was identified in 160 of 168 (95.2%) patients of the statin group compared with only 125 of 472 (26.5%) of the no-statin group. Of the 640 patients, 24 (3.8%) developed MACE. Multivariate Cox hazard regression analysis identified statin therapy as a significant negative predictor of MACE (hazard ratio, 0.11; 95% CI, 0.02-0.84; P=0.033). In the propensity-score matched cohorts (n=128 each), Kaplan-Meier survival curve showed a better 5-year MACE-free survival rate for patients of the statin group compared to the no-statin group (100% vs 91.7%, respectively; P=0.002). CONCLUSIONS Statin therapy correlated with a lower rate of cardiovascular events in VSA patients free of significant organic stenosis. Statins seems to improve the prognosis of VSA patients free of significant organic stenosis.

Abstract
Angina with "normal coronary arteries" might best be thought of as "angina with coronary dysfunction". It seems likely that this syndrome is due to inadequate regional myocardial perfusion with manifestations similar to those seen when ischemia results from occlusive coronary artery disease. The prognosis of the disorder is favorable, but occasional catastrophic events occur. It appears likely that maldistribution of perfusion results from dynamic changes affecting proximal, and perhaps distal coronary vessels, potentially mediated by vasoactive substances released from platelets precipitating or exacerbating coronary arterial spasm. Clarification of the pathogenesis of the syndrome should permit implementation of more effective therapy and prevention of the rare malignant sequelae of this disorder.

Abstract
BACKGROUND Hyperglycemia on admission is associated with increased mortality rates in patients with ST-elevation myocardial infarction (STEMI) who are treated with either fibrinolytic therapy (FT) or primary percutaneous coronary intervention (PCI). However, data regarding the relationship between hyperglycemia and the success of FT are lacking. The aim of this study was to investigate the value of admission blood glucose for the prediction of failed reperfusion following FT. METHODS AND RESULTS This is a retrospective study of 304 STEMI patients who received FT and whose admission glucose levels were recorded. The main outcome measure was ST segment resolution≥50%. The median (interquartile range [IQR]) blood glucose level in the entire study group was 112 (95-153). In 92 (30.2%) patients, FT was unsuccessful and rescue PCI was performed. Admission glucose (126 [99-192] vs. 110 [94-144] mg/dL, p<0.001), time from symptom onset to FT (180 [120-270] vs. 150 [120-180] min, p=0.009), and maximum ST elevation amplitude (3 [2-7] vs. 3 [2-6] mm, p=0.05) were higher in the failed reperfusion group than in the reperfusion group. Admission hyperglycemia was an independent predictive factor for failed reperfusion (hazard ratio 4.79 [1.80-12.76], p=0.002), along with time from symptom onset to fibrinolysis and anterior wall myocardial infarction. CONCLUSIONS In patients with STEMI who undergo FT, admission hyperglycemia is an independent predictor of the failure of fibrinolysis.

Abstract
BACKGROUND Variant angina, or vasospastic angina, is a form of angina caused by vasospasm of the coronary arteries, probably caused by endothelial dysfunction. This form of angina is provoked by non-classical risk factors such as stress, alcohol use, use of sympathomimetics and low environmental temperatures, but also by smoking. Treatment is based on elimination of risk factors and vasodilator therapy with nitrates and long-acting calcium antagonists. CASE DESCRIPTION We present a 68-year-old woman with recurring thoracalgia at rest and during exercise, suggestive of severe variant angina in more than one coronary artery. Despite elimination of risk factors and administration of vasodilatory therapy the treatment was initially insufficient. It eventually emerged that the probable cause was frequent use of a vasoconstrictive nasal spray, although this was not described in literature, and not originally mentioned by the patient. CONCLUSION A thorough case history is of vital importance in a patient presenting with a history suggestive of variant angina. Even undescribed and apparently less important risk factors can be responsible for persistence of symptoms, and can lead to an applied treatment not producing the desired result.

Abstract
OBJECTIVE To investigate the efficacy of coronary stenting in patients with variant angina refractory to medical treatment. SUBJECTS AND METHODS Variant angina was diagnosed in 81 patients admitted to the Department of Cardiology between January 2003 and June 2011. However, coronary stenting was performed in 21 patients refractory to medical treatment, but coronary angiography and intravascular ultrasound were performed in all patients, and acetylcholine provocative test was performed in 11 of the 21 patients refractory to medical treatment. Coronary angiography was repeated after 9-12 months in the 21 patients with coronary stents. Clinical follow-up time was 2.5 ± 3.1 years (range 1-8). RESULTS Of the 81 patients, coronary angiography and intravascular ultrasound did not reveal significant stenosis in 13 (16.0%), but revealed 20-75% fixed stenosis in the remaining 68 (84.0%) patients. The acetylcholine provocative test was positive in the 11 patients. Of the 21 patients with coronary stents, the spasm site was located in the right coronary artery in 16 (76.2%) and in the left anterior descending artery in the remaining 5 (23.8%) patients. During the 1- to 8-year follow-up period, 1 of the 21 patients with stents developed recurrent episodes of variant angina, 5 patients had occasional chest pain, and the other 15 were asymptomatic. Coronary angiography at 9-12 months after initial evaluation demonstrated no stenosis in 3 patients, 20-40% in-stent mild intimal hyperplasia in 15 patients, and 50-80% in-stent restenosis in 3 patients. Coronary stenting was performed again in 2 patients. CONCLUSIONS The present study showed that coronary stenting for severe refractory coronary vasospasm was effective and without serious complications. It can be an alternative and viable option for some patients who are refractory to medical therapy and at a high risk of acute coronary syndrome recurrence.

Abstract
Spastic angina is considered rare but its prevalence is probably underestimated especially in case of atherosclerotic coronary lesions. Its diagnosis remains important due to its poor prognosis and therapeutic characteristics. We report three clinical cases illustrating two different clinical presentations and the problem of diagnosis of spastic angina. We performed a review of the literature essentially concerning commonly used diagnosis means and especially provocative testing for coronary spasm. This test needs to be adapted to the evolution of techniques and uses of coronary angiography in 2011, particularly the wide spread use of radial approach. Therefore new recommendations are needed, specifying the terms of provocative testing and establishing clear diagnosis criteria including clinical, electrocardiographic and angiographic data. Such guidelines would probably help to better diagnose and treat these patients in our practice.

Abstract
We report a case of recurrent variant angina pectoris which occurred even while receiving antispastic treatment. Coronary angiography revealed no obvious lesion. Behçet's syndrome was diagnosed based on recurrent oral aphthous and genital ulcer as well as skin manifestation. After treatment with immunosuppressant, neither angina nor oral ulcer relapsed. We strongly believe that the variant angina is due to coronary vasospasm induced by Behçet's syndrome in this patient.

Abstract
Wellens syndrome is characterised by negative or biphasic T waves in V2-V4 leads and critical stenosis of proximal part of the left descending coronary artery. These ECG changes without atherosclerotic changes in coronary angiography, i.e. coronary artery spasm are called pseudo-Wellens syndrome. We describe a patient with acute coronary syndrome and pseudo-Wellens syndrome as a cause of vasospastic angina. These ECG abnormalities need differentiation with acute pulmonary embolism.

Abstract
A 65-years-old female presented with features suggesting acute coronary syndrome, initially as non STEMI and later as classical Prinzmetal's angina. While being treated she also had recurrent episodes of dizziness and cardiac arrest due to complete heart block and asystole. These episodes occurred while on nitroglycerine infusion and were not accompanied by chest pain or ST-T segment changes. Coronary angiography revealed evidence of reversible multi-vessel coronary spasm. Electrophysiological studies were normal. She was treated with nitrates and calcium blockers and a permanent pacemaker implantation.

Abstract
The study reports on the outcome of hyperventilation tests in a 57-year-old male with Prinzmetal's variant angina, formerly often complicated by ventricular fibrillation. It was found that hyperventilation for a period of 6 min after a delay of 4 to 6 min was followed by the development of ST-elevation and pain, but only when the test was performed in the morning, whereas the outcome of tests performed later in the day were negative. Pretreatment with calcium blockers, nifedipine or verapamil proved effective in preventing the anginal response to the test, also when it was performed in the morning. It is concluded that hyperventilation performed in the early morning, but not later in the day, may prove to be an effective and safe procedure for provoking Prinzmetal's variant angina, and that hyperventilation may be useful in the evaluation of the efficacy of drug therapy.

Abstract
Angina pectoris is a clinical syndrome caused by transient myocardial ischaemia due to an imbalance between myocardial oxygen demand and supply. It is now evident that coronary artery spasm plays an important role in the pathogenesis of various forms of angina pectoris. Angina pectoris that is mainly caused by coronary artery spasm (coronary spastic angina) has one or more of the following characteristics: 1) the attack occurs at rest, 2) the attack is associated with ST-segment elevation in the ECG, 3) the attack has a variable exercise threshold, and 4) the attack is suppressed by Ca-antagonists but not by beta-adrenergic blocking agents. On the other hand, angina pectoris that is caused by increased myocardial oxygen demand in the presence of severe and extensive organic stenosis (organic angina) has the following characteristics: 1) the attack is induced by constant amount of exertion irrespective of hour and day and is relieved by rest, 2) the attack is associated with ST-segment depression in the ECG, and 3) the attack is suppressed by beta-adrenergic blocking agents, which decrease myocardial oxygen demand.

Abstract
A coronary arteriovenous (AV) fistula consists of a communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common anomaly that can affect coronary perfusion. Yet bilateral involvement of a coronary fistula, constitutes an uncommon subgroup of coronary AV fistulas. We herein report on a case of bilateral coronary AV fistula that was coexistent with variant angina originating from the distal right ventricular branch of the right coronary artery and the distal septal branch of the left anterior descending artery, and the latter drained into the right ventricle.

Abstract
Sirolimus-eluting stents (SES) prevent neointimal proliferation and have been widely used to treat stenotic lesions in coronary arteries because of a significant reduction of restenosis in comparison with bare-metal stents. Sirolimus, however, may cause endothelial dysfunction by damage to vascular endothelium or impairing vascular repair. Recent studies report the occurrence of exercise- or acetylcholine-induced coronary vasoconstriction in the vessel segments adjacent to the SES. We report here a clinical case of intractable Prinzmetal's angina 3 months after SES implantation and recommend extended, thorough follow up of patients who have undergone SES implantation.

Abstract
A case of a 79-year-old man with risk factors of ischaemic heart disease is presented. He was admitted to the Cardiology Ward because of recurrent angina pectoris with ST-segment elevation in the anterior electrocardiographic leads. Coronary arteriography revealed 90% stenosis of the marginal branch of the left coronary artery, which was supplied by coronary angioplasty. During hospitalisation recurrent episodes of angina pectoris were noted, only in night hours, with ST-segment elevations in anterior electrocardiographic leads. Pharmacotherapy with calcium blockers and nitrates eliminated the episodes of chest pain in a ten-month follow-up.

Abstract
We report the case of a 32-year-old man who presented at the emergency department with severe chest pressure, left arm pain, and dizziness. These symptoms were described as intermittent, occurring after exercise and at rest. He had undergone several stress tests during the past 8 years, but no objective evidence of ischemia was produced. His history of hyperlipidemia and increasing frequency of symptoms prompted us to perform coronary angiography, which showed a single coronary artery with an ostium at the right sinus of Valsalva. The vessel had an initial, mixed common trunk that gave rise to both the right coronary artery proper and to the left coronary artery. The left main trunk followed a prepulmonic course. The anatomic features were eventually confirmed by computed tomographic angiography. The left main stem had a fixed 50% to 60% area narrowing, at baseline study. A treadmill stress myocardial perfusion study showed no evidence of ischemia. The patient was referred to a 2nd facility, where intravascular ultrasonography, at baseline, revealed 63% left main narrowing without evidence of atherosclerosis. Acetylcholine provocation demonstrated worsening of the stenosis to about 80%, with reproduction of angina and ST-segment depression, which indicated that medical management of spasm might provide symptomatic relief.

Abstract
We report an unusual case of a male patient with vasospastic angina in whom the pattern of coronary artery spasm changed after coronary stenting. The patient was admitted to our hospital with an acute coronary syndrome. Coronary angiography revealed an intermediate grade stenosis in the right coronary artery, and focal coronary spasm was provoked by intracoronary acetylcholine. A diagnosis of vasospastic angina was made, and the patient was followed medically. He subsequently was readmitted with refractory vasospastic angina and underwent coronary stenting. He was pain-free after stent implantation. Repeat angiography 6 months later showed no restenosis in the stented segment; however, coronary spasm was provoked in all areas except the stented segment by intracoronary acetylcholine injection.

Abstract
Vasospastic angina is associated with ventricular arrhythmias, acute myocardial infarction and sudden arrhythmic death. The main ischemic mechanism in vasospastic angina is coronary spasm. Because the demonstration of spontaneous coronary spasm is difficult, a number of methods which can provoke spasm in susceptible patients were imagined. The most used clinical methods of diagnostic provocation testing were analyzed.

Abstract
A case of a 49-year-old woman with episodes of syncopes as a first manifestation of variant angina is presented. She was admitted to cardiology ward because of recurrent angina associated with marked ST segment elevation in the inferior and anterior electrocardiographic leads. Previously she was diagnosed at a neurological ward because of nocturnal syncopes without accompanying chest pain but with associated hypotonia and bradycardia of about 36 beats/min. Coronary arteriography revealed non-significant coronary stenosis of two vessels (left and right coronary artery) and coronary spasm close to these obstructions. Therapy with calcium channel blockers as well as giving up smoking eliminated the episodes of chest pain and syncope in a twelve-month follow-up.

Abstract
Patients with variant angina represent a diagnostic and therapeutic dilemma. Variant angina is a disease with various causes, variations in treatment guidelines and variable prognosis. In an era of robotic cardiac surgery and automatic cardioverter defibrillators, it is regrettable that we lack enough information on the optimal management of this entity. Lack of randomised trials and a tendency for spontaneous remissions makes interpretation of results difficult. We review the pathophysiology, presentation and recent developments in medical and surgical management of variant angina. Literature is full of conflicting data and it is difficult to make specific recommendations.

Abstract
We describe a postmenopausal women with new onset of variant angina caused by thyrotoxicosis due to Graves' disease. During exercise bicycle ergometry at 50 Watts, the patient developed typical angina with ST segment elevation in the precordial leads. A coronary angiogram revealed normal coronary arteries. Graves' disease with overt hyperthyroidism was diagnosed. After achieving an euthyroid state with administration of propylthiouracil, the symptoms resolved completely and the patient had a normal exercise capacity without electrocardiographic changes. Thus, we conclude that in patients with thyrotoxicosis, variant angina and normal coronary arteries, restoration of normal thyroid function may be curative.

Abstract
Coronary artery anomalies continue to constitute a confusing subject in modern cardiology. While most anomalies are considered to have a benign prognosis, the literature and cardiologic culture frequently imply an intrinsic, systematic association of coronary anomalies with severe clinical presentations. We present a case of unusual single coronary artery, in order to elucidate the logical process that should be used to study similar cases. A 56-year-old female presented with a 6-year history of atypical chest pain and an abnormal electrocardiogram. Heart catheterization revealed an abnormal coronary tree interpreted by some observers as a benign coronary anomaly, by others to indicate the need for coronary angioplasty. A nuclear stress test was performed after 1 year of unrelenting symptoms and showed mildly abnormal findings, leading to a more definitive angiographic study that clarified the anatomy and the prognosis. The case is essentially and only an example of single coronary artery with origin of all branches from the right coronary sinus, but with an unusual triple origin of the branches serving the left anterior descending territory. The notion that a case of single coronary artery may have significant prognostic and clinical repercussion is frequently repeated in the current inconclusive literature. A rational discussion should deal both with individual case objective evidence and theoretical general consideration.

Abstract
OBJECTIVES This study sought to clarify the relationship between the degree of intracellular magnesium deficiency and the frequency of anginal attacks in women with variant angina. PATIENTS AND METHODS We evaluated the intracellular and extracellular magnesium status of twelve women with variant angina: group A (> or = 4 attacks/week, n = 5) and group B (< 4 attacks/week, n = 7). Magnesium levels were determined in serum, urine, and erythrocytes, and the 24-h magnesium retention rate was calculated by magnesium loading test. RESULTS Group A showed a higher 24-h magnesium retention rate (58.2 +/- 9.1% vs. 31.3 +/- 4.4%; p < 0.01) and a lower intracellular concentration of magnesium in erythrocytes than group B (3.1 +/- 1.1 vs. 5.0 +/- 0.8 fg/cell; p < 0.05), demonstrating the presence of magnesium deficiency in group A. The 24-h magnesium retention rate and intracellular concentrations of magnesium in erythrocytes correlated well with the activity of variant angina (r = 0.61, p < 0.01; and r = -0.74, p < 0.01, respectively) for these patients. CONCLUSION This study demonstrates that the degree of intracellular magnesium deficiency in women with variant angina is closely related to the frequency of chest pain.

Abstract
In addition to coronary atherosclerotic disease, coronary thromboembolism can also lead to acute coronary syndromes. However, coronary thromboembolism due to prosthetic heart valves is very rare and not very well-known. It have been reported only a few cases. In this paper, we present a rare case with vasospastic angina pectoris secondary to coronary thromboembolism in a patient with prosthetic heart valves.

Abstract
We report a primigravida woman with acute myocardial infarction caused by coronary artery spasm induced by intravenous administration of methyl ergometrine maleate just after delivery. Despite the frequent usage of ergot derivatives to promote uterine contractions, cardiac complications related to this drug are rare. Myocardial infarction may be overlooked in young women in the early postpartum period. Careful monitoring and prompt evaluation should be performed when this drug is administered for obstetrical purposes.

Abstract
We report about a 49 year old woman with repeated chest pain at rest. During hyperventilation significant ST-segment elevation in leads V1-V5 appeared. Bicycle stress test did not provoke any ECG changes. Coronary angiography showed a significant stenosis of the left anterior descending coronary artery. Successful balloon angioplasty followed by stent implantation was performed. After an uneventful course of twelve months, hyperventilation could provoke neither chest pain nor ECG changes again without any antispastic medical treatment. Impact of fixed atherosclerotic lesions for the occurrence of coronary vasospasm, usefulness of hyperventilation as a non-invasive provocation test and therapy are discussed.

Abstract
CASE REPORT A 41-year-old male saw his general practitioner because of progressive atypical angina symptoms and palpitations for the last 7 years. Chest X-ray showed a mediastinal mass. Further investigation by computed tomography (CT), magnetic resonance imaging (MRI) and cardiac catheterization revealed two bronchogenic cysts. After median sternotomy and pericardial incision, two cystic masses were found on top of and dorsal to the right atrium. Following resection, the patient was free of previously experienced problems related to his atypical angina symptoms. Histological investigation showed no signs of malignancy. CONCLUSION In patients with atypical angina pectoris the rare case of a bronchogenic cyst has to be considered a possible reason for the symptoms. In addition, patients might show atrium-induced dysrhythmia, coughing with purulent sputum, and pain. CT and MRI are absolutely necessary for exclusion of metastases and aneurysms in the mediastinum.

Abstract
K(ATP) channels couple the intracellular energy state to membrane excitability and regulate a wide array of biologic activities. K(ATP) channels contain a pore-forming inwardly rectifying potassium channel and a sulfonylurea receptor regulatory subunit (SUR1 or SUR2). To clarify the role of K(ATP) channels in vascular smooth muscle, we studied Sur2 gene-targeted mice (Sur2(-/-)) and found significantly elevated resting blood pressures and sudden death. Using in vivo monitoring, we detected transient, repeated episodes of coronary artery vasospasm in Sur2(-/-) mice. Focal narrowings in the coronary arteries were present in Sur2(-/-) mice consistent with vascular spasm. We treated Sur2(-/-) mice with a calcium channel antagonist and successfully reduced vasospastic episodes. The intermittent coronary artery vasospasm seen in Sur2(-/-) mice provides a model for the human disorder Prinzmetal variant angina and demonstrates that the SUR2 K(ATP) channel is a critical regulator of episodic vasomotor activity.

Abstract
The authors report on the case of a 61 year-old female patient who was repeatedly taken to hospital because of chest pain and temporary loss of consciousness. During her hospitalization there was no ST elevation on the ECG, sinus bradycardia, other times atrial fibrillation was detected. The diagnosis was made by Holter monitoring three years after the onset of complaints. At this time chest pain set in after midnight, which was followed by loss of consciousness. Significant ST elevation and IIIrd degree AV block were detected. The coronarography showed non-significant coronary stenosis. According to the vasospastic patomechanism nitrate, calcium antagonist and acetylsalicylic acid therapy was administered and because of the complete AV block leading to syncope a VVI, M pacemaker was implanted. During the two years passed since the implantation of the pacemaker the patient had chest pain only once and it was not accompanied by syncope.

Circadian variation of autonomic nervous activity in patients with multivessel coronary spasm. JAPANESE CIRCULATION JOURNAL 2001; 65:593-8.

Abstract
The present study investigated whether the circadian rhythm of sympathovagal activity is related to the severity of coronary spasm or multivessel coronary spasm. Heart rate variability was examined in 22 consecutive patients with vasospastic angina provoked by intracoronary injection of acetylcholine, who had either multivessel spasm (Group M, n=11 ) or single vessel spasm (Group S, n= 11), in 20 subjects without coronary artery disease (Group C) and 20 patients with effort angina who had organic coronary artery stenosis (Group E). The frequency domain indices were analyzed, including low frequency (LF: 0.04-0.15 Hz) and high frequency (HF: 0.15-0.4Hz), the latter being an index of efferent parasympathetic activity, and the ratio (L/H) as an index of sympathovagal balance. The circadian variation of the parameters was analyzed by its pattern and was quantified by the difference of the mean values between daytime and nighttime. Although the HF power increased during nighttime in Groups C and S, this increase was attenuated in Groups E and M. The circadian variation of the L/H ratio (ie, a drop during nighttime) was smaller in the S and M groups than in Groups C and E. Accordingly, in Group M, the circadian variation of both sympathetic and parasympathetic nervous activity was attenuated, but in Group S, the variation of sympathetic nervous activity, but not parasympathetic nervous activity, was decreased. These data suggest that relatively enhanced sympathetic nervous activity at night may be involved in the mechanism underlying multivessel coronary spasm.
