The decreased 123I-BMIPP uptake, while having normal perfusion, in the correspondent coronary artery territory is caused by a delayed metabolic recovery after the recovery of perfusion. This phenomenon termed ischemic memory can clearly differentiate vasospastic angina from other chest pain syndromes.

Pulmonary vein isolation is an effective treatment for patients with atrial fibrillation (AF).Although vasospastic angina (VSA) is not a common complication after ablation of AF, we report 3 cases of VSA following ablation of persistent AF. Two of the 3 patients felt chest pain following pulmonary vein isolation, and complex fractionated atrial electrogram ablations were performed. ST elevation in the inferior leads and atrioventricular block occurred because of severe coronary vasospasm. In the third patient, the electrocardiography monitor detected transient ST elevation within an hour after ablation...

Acetylcholine is widely used for a diagnostic provocation test of coronary spasm in patients with vasospastic angina. Acetylcholine usually induces coronary vasodilatation mediated by muscarinic receptor activation, but sometimes it evokes vasoconstriction of coronary arteries where the endothelium is damaged. Early repolarization syndrome is characterized by a J wave observed at the end of the QRS complex in a surface electrocardiogram. The J wave is attributed to the transmural voltage gradient at the early repolarization phase across the ventricular wall, which stems mainly from prominent transient outward current in the epicardium, but not in the endocardium...

The primary symptom of ischemic heart disease is typically chest pain, but in some cases, this pain may radiate to the maxillofacial region. This article describes the case of a 44-year-old man with orofacial pain of cardiac origin. The patient was suspected to be suffering from cardiac disease by the oral and maxillofacial surgeon and was referred to a cardiologist, where he received a heart examination. The patient was diagnosed by means of cardiac catheterization as having coronary spastic angina. During catheterization, intracoronary ergonovine maleate induced orofacial pain that was almost the same in character and intensity as the patient's first episode...

Vasospastic angina, also known as Prinzmetal's angina, is thought to occur due to vascular hyper-reactivity to various stimuli. Response to medical therapy is usually good; however, 1 out of 5 patients has resistant symptoms. Rarely, potentially lethal arrhythmias can occur due to vasospasm, and those patients are reported to have a poorer prognosis. Presently described is a case of resistant vasospastic angina with persistent symptoms under calcium channel blocker and nitrate treatment. The patient presented with hemodynamically unstable rapid-rate ventricular tachycardia, which was quite resistant to recurrent cardioversion...

Coronary spasm is a well-documented, though rare, condition that can mimic myocardial infarction and is usually found in only a single vessel during an event. We describe the case of a 43-year-old male with past medical history of hypertension, hyperlipidemia, tobacco abuse, and with no known coronary disease. The patient developed chest pain 3 days postadmission for primary diagnosis of psychiatric disorder. The patient had a positive stress study with moderate reversible ischemia in the anterolateral region...

Mutations in the T786C endothelial nitric oxide synthase gene (eNOS) are associated with osteonecrosis and Prinzmetal's angina. Nitric oxide is necessary for bone health and ameliorates Prinzmetal's angina. This study compared mutations of T786C eNOS in 146 patients with primary osteonecrosis, 114 patients with Prinzmetal's angina, and 83 normal control subjects. Patients with osteonecrosis had more mutant eNOS alleles than control subjects (42% vs 22%, respectively; P<.0001) but had the same number of mutant alleles as patients with Prinzmetal's angina (42% vs 41%, respectively; P=...

Recently, exercise-induced spastic coronary artery occlusion at the site of moderate stenosis, which Prinzmetal's angina or cardiac syndrome X does not cover, was reported. Multi-modality imaging is important for the diagnosis of coronary artery disease with a complex ischemic mechanism. However, the previous report did not include findings from intracoronary imaging at the site of moderate coronary stenosis. We report a case of exercise-induced vasospastic angina at the site of moderate stenosis, where multi-modality imaging, including exercise stress echocardiography and intravascular ultrasound, was utilized to make a definitive diagnosis and investigate underlying causes...

Coronary artery vasospasm can cause recurrent anginal episodes with ST-segment elevation. Vasospasm induced myocardial ischemia can lead to arrhythmias including life threatening ventricular tachycardia (VT). Percutaneous coronary intervention (PCI), although not routinely recommended for treating vasospastic angina, can be considered for discrete coronary spasm that is not amenable to vasodilator therapy. We present a challenging case of a 41-year-old lady with recurrent episodes of vasospastic angina and VT refractory to medical therapy, which was successfully treated with PCI and an implantable cardioverter defibrillator...

Refractory coronary vasospasm subsequent to reperfusion, such as cardiopulmonary resuscitation or revascularization, for myocardial infarction may respond to fasudil in the superacute phase. Continuous low-dose fasudil administration should be an option for refractory coronary vasospastic angina (VSA).

BACKGROUND: We investigated the association between initial ST-segment change after return of spontaneous circulation (ROSC) and the incidence of acute coronary lesions in patients with out-of-hospital cardiac arrest (OHCA), and clinical outcomes of patients with OHCA caused by vasospastic angina pectoris (VSA). METHODS: Among 2779 OHCA patients in our institution, all patients with ROSC underwent emergent coronary angiography (CAG) except for those with an obvious extra-cardiac cause of OHCA...

No data are available on the association of serum uric acid and vasospastic angina (VSA) which has endothelial dysfunction as a possible pathophysiologic mechanism. Low uric acid level might cause adverse outcomes in VSA in connection with endothelial dysfunction. We enrolled 818 VSA patients whose uric acid level was measured at admission. Patients were categorized according to tertiles of uric acid level: group I, ≤ 4.8 mg/dL; group II, 4.9-5.9 mg/dL; and group III, ≥ 6.0 mg/dL. Primary outcome was major adverse cardiac events (MACEs), defined as a composite of cardiac death, acute myocardial infarction (MI), ischemic stroke, coronary revascularization, and rehospitalization for angina...

BACKGROUND: Little is known about the impact of stent type on the prognosis of vasospastic angina (VSA) in patients who undergo stent implantation.Methods and Results:We evaluated consecutive patients undergoing coronary angiography with positive (n=650; VSA) and negative (n=2,872; non-VSA) ergonovine testing. Among them, 304 patients undergoing stent implantation for organic stenosis were classified for comparison into 3 respective VSA and non-VSA groups based on stent type (68 and 78 with bare-metal stent [BMS]; 21 and 49 with sirolimus-eluting stent [SES]; 26 and 62 with newer generation drug-eluting stent [N-DES])...

A 41-year-old woman developed cardiac arrest after administration of misoprostol in order to induce an abortion. She was successfully resuscitated. Coronary angiography revealed coronary artery spasm which responded to nitroglycerine. Misoprostol is first-line treatment for medically induced abortion. Reports have described cardiovascular adverse events in women with cardiovascular risk factors, and clinicians should be aware of this.

A 51-year-old man with a resuscitation episode was referred to our hospital. Coronary angiography revealed a focal spasm overlapped with organic stenosis where a bare metal stent was implanted. Acetylcholine (ACh) provocation test did not induce chest pain. It revealed no discernible ST-T changes but unmasked a J wave at the end of the QRS complex, which was associated with short-coupled repetitive premature ventricular beats. A J wave reportedly appears immediately before the onset of ventricular fibrillation caused by vasospastic angina...

BACKGROUND: Men are more likely to suffer from vasospastic angina (VSA) than women; however, gender differences in the long-term prognosis of VSA patients have not been fully elucidated. We sought to investigate clinical outcomes and predictive factors of VSA patients according to gender. METHODS: A total of 986 patients (838 men and 148 women) with a positive result on intracoronary ergonovine provocation test between January 2003 and December 2014 were analyzed...
