: Angina pectoris in pregnancy is unusual and Prinzmetal's angina is much rarer. It accounts for 2% of all cases of angina. It is caused by vasospasm, but the mechanism of spasm is unknown but has been linked with hyperthyroidism in some studies. Patients with thyrotoxicosis-induced acute myocardial infarction are unusual and almost all reported cases have been associated with Graves' disease. Human chorionic gonadotropin hormone-induced hyperthyroidism occurs in about 1.4% of pregnant women, mostly when hCG levels are above 70-80 000 IU/L...

BACKGROUND: Smoking and other risk factors have been well known as important factors of variant angina or coronary artery spasm (CAS). However, clinical features related to age on coronary artery spasm have been rarely evaluated. METHODS: We evaluated 3155 consecutive patients with insignificant coronary artery lesion. Patients underwent Acetylcholine (Ach) provocation test for induction of CAS. CAS was defined as > 70% luminal narrowing of coronary arteries during Ach provocation test...

We investigated the clinical situations and the present knowledge of Japanese cardiologists about coronary artery spasm before and after the establishment of guidelines for this condition in the real world. A questionnaire was developed regarding the number of cases of coronary angiography, percutaneous coronary intervention, and invasive/non-invasive spasm provocation tests before (2008) and after (2014) the establishment of the Japanese Circulation Society (JCS) guidelines for coronary artery spasm and the status of spasm provocation tests...

BACKGROUND: Drug-eluting stent (DES) -induced coronary vasospasm is a well known phenomenon after stent implantation; however, the extent of this risk is still unknown. We report a case in which DES-induced severe coronary vasospasm was clinically suspected as a cause of subacute stent thrombosis (ST). CASE PRESENTATION: A 67-year-old man came to our hospital due to chest pain with mild exercise. He was diagnosed with effort angina by coronary angiography and underwent DES implantation in the mid-left ascending artery (LAD) after the administration of dual anti-platelet therapy...

PURPOSE: Calcium channel blockers diltiazem and nitrate have been used as selective coronary vasodilators for patients with significant coronary artery spasm (CAS). However, no study has compared the efficacy of diltiazem alone versus diltiazem with nitrate for long-term clinical outcomes in patients with CAS. MATERIALS AND METHODS: A total of 2741 consecutive patients without significant coronary artery disease with positive CAS by acetylcholine (Ach) provocation test between November 2004 and May 2014 were enrolled...

According to the Japanese Circulation Society guideline of vasospastic angina, incremental doses of acetylcholine (ACh) are prescribed for coronary spasm provocation: 20 and 50 μg for the right coronary artery (RCA), and 20, 50 and 100 μg for the left coronary artery (LCA). However, provocation by low doses of ACh in patients with low vasoreactivity may be less needed, and the requirement of 50 μg of ACh for the LCA in these patients has not been evaluated. In the present study, patients who underwent ACh provocation test for both the RCA and LCA were included...

Vasospastic angina is considered rare in Europe but with a prevalence probably underestimated and affects preferentially men in published studies, mostly involving Asian populations. Vasospastic angina in the female population have specificities in terms of pathophysiology, clinical presentation and prognosis, as well as diagnostic strategies currently recommended, that we describe from a clinical case. Although known for over 50years, vasospastic angina remains a disease still insufficiently researched, probably even less in women...

INTRODUCTION: Myocardial bridging (MB) is a congenital variant of the coronary artery in which a portion of the epicardial coronary artery takes an intramuscular course. Although it is considered a benign anomaly, it may lead to such complications as myocardial ischaemia, acute coronary syndrome, coronary spasm, exercise-induced dysrhythmias or even sudden death. MB may be related to increased inflammatory and atherosclerotic processes. This study was conducted with the aim of evaluating the relationship between neutrophil/lymphocyte ratio (NLR) and MB...

Spontaneous coronary artery vasospasm is one of the important causes of acute chest pain syndromes. The diagnosis of diffuse multifocal spasm can be quite challenging and it could be easily mistaken for diffuse coronary artery disease. The use of intracoronary nitroglycerin can relieve spasm and reveal the real extent of coronary artery disease. Herein we present a case presenting with acute myocardial infarction due to severe coronary artery spasm that had even received fibrinolytic therapy. Multiple narrowing was shown during coronary angiography and the patient was scheduled for percutaneous coronary intervention (PCI)...

Coronary vasospasm is uncommon during pregnancy and the postpartum period. We present a very rare case of an acute coronary vasospasm in a 36-year-old woman who was two weeks postpartum. The coronary arteriograms showed a coronary vasospasm in the distal left anterior descending and circumflex coronary arteries. Electrocardiogram (ECG) presentation was atypical, with T-wave inversions in leads I, aVL, and V2 to V6. To our knowledge, this is the first case with a well-documented coronary artery vasospasm in a postpartum woman without the classic ST elevation on ECG...

Methylphenidate (Ritalin(®)) is an increasingly used medication in the treatment of attention-deficit hyperactivity disorder (ADHD). Cardiovascular adverse effects like vasospasm or myocardial infarction are described as very rare adverse effects. We present the case of a 21-year-old man diagnosed with ADHD who recently started therapy with Ritalin(®) Adult 20 mg for at least 3 days. Afterwards he presented with chest pain, elevated troponin and creatine kinase, and posterolateral ST elevations. A myocarditis was initially supposed...

A 50 yr old female developed transient ST segment elevation due to an acute coronary vasospasm following a Indian Red Scorpion sting and the angiogram revealed 50% occlusion in right coronary artery (RCA).The possible mechanism is that the sympathetic over-activity could have aggravated the occlusion in the RCA as the RCA is more commonly prone to spasm compared to the other coronary arteries.

BACKGROUND AND OBJECTIVES: Cigarette smoking is a risk significant factor in coronary artery disease (CAD) and vasospastic angina (VSA). However, it is largely unknown whether smoking adds to any long-term clinical risk in VSA patients. SUBJECTS AND METHODS: A total of 2797 patients without significant CAD underwent acetylcholine (Ach) provocation test between November 2004 and October 2010. Patients were divided into three groups, based on the presence of coronary artery spasm (CAS) and smoking habits (non-CAS group: n=1188, non-smoking CAS group: n=1214, smoking CAS group: n=395)...

AIMS: Although the importance of coronary microvascular dysfunction (CMD) has been emerging, reliable biomarkers for CMD remain to be developed. We examined the potential usefulness of plasma concentration of serotonin to diagnose CMD in patients with suspected angina and unobstructive coronary arteries. METHODS AND RESULTS: We enrolled 198 consecutive patients (M/F 116/82, 60.2 ± 13.3 years old) who underwent acetylcholine provocation test and measured plasma serotonin concentration...

Takotsubo cardiomyopathy (TTS) is a peculiar clinical condition often affecting postmenopausal women after a stressful trigger. The underlying mechanisms have not been completely elucidated but several hypotheses have been advanced, with catecholamine cardiotoxicity, microvascular dysfunction and coronary artery spasm each suggested to play a role. The incidence of stroke after TTS appears to range from 0% to 7.7%, and interestingly TTS has been described as both a cause and a complication of stroke. We sought to assess the incidence and predictors of stroke during the index event (peri-index event stroke) in a heterogeneous TTS population...
