OBJECTIVE: Raynaud phenomenon is a vasospastic disorder affecting the hands and feet, and the efficacies of traditional treatments, such as pharmacological therapies and sympathectomy, are not uniform. Patients with paraneoplastic Raynaud phenomenon do not benefit from the traditional treatments. The use of botulinum toxin type A (BTX-A) for Raynaud phenomenon has been reported for several years; however, there are few reports regarding botulinum toxin type A in the treatment of paraneoplastic Raynaud phenomenon...

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...

OBJECTIVE: Multi-slice computed tomography (MSCT) coronary angiography has been reported as an effective alternative to invasive conventional coronary angiography (CCA) for the diagnosis of coronary artery disease (CAD). However, in previous reports, the diagnostic accuracy of MSCT has not been significant enough to be of benefit in symptomatic patients. The aim of this study was to identify the usefulness of 320-slice computed tomography coronary angiography (320-CTA) for symptomatic patients in terms of the diagnostic accuracy of 320-CTA and the prevalence of vasospastic angina pectoris (VSAP) within the study cohort...

Calcium channel blockers (CCB) differ in their effects on the cardiovascular system with diltiazem being less negatively ionotrop as compared to verapamil. Diltiazem is mainly used to treat supraventricular tachycardia, vasospastic angina and the Raynaud's syndrome. Little is known about the molecular effects of benzothiazepins on cardiac gene expression. We therefore investigated the effects of diltiazem on cardiac gene expression in normotensive and hypertensive rats with left ventricular hypertrophy and compared the results with our previous findings on verapamil and nifedipine...

Subarachnoid hemorrhage (SAH) following rupture of an intracranial is associated with high mortality and morbidity. The late deterioration of the patient's neurological status or late cognitive dysfunctions even after secure clipping or decent endovascular treatment which is defined as delayed ischemic neurological deficits recently has been attributed to vasospasm. Due to the failure of specific anti-vasospastic agents in clinical trials researchers focused to explore new pathological mechanisms to be responsible for the delayed deterioration of the patients suffering from SAH...

BACKGROUND: Following digital surgical procedures, the ensuing post-operative course may be complicated by the presence of underlying ischaemic or vasospastic process. In the presence of such conditions, post-operative ischaemic changes may be further exacerbated with the use of local anaesthetics in combination with epinephrine. CASE DETAILS: We report a 21 year-old female who presented with an amputated fifth digit due to a rapidly spreading gangrene which started immediately after the surgical repair of a traumatic laceration which was infiltrated with a pre-mixed solution of lignocaine and epinephrine 3 hours earlier...

BACKGROUND: Limited data are available on the efficacy of statin therapy for secondary prevention in patients with vasospastic angina (VSA). We investigated the association of statin therapy with long-term clinical outcomes in VSA patients without significant coronary artery disease. METHODS: From January 2003 to June 2014, we enrolled a total of 804 patients with VSA proven by an ergonovine provocation test without significant (≥70% diameter stenosis) coronary artery disease...

OBJECTIVES: This study aimed to review the efficacy of exercise training for improving cutaneous microvascular reactivity in response to local stimulus in human adults. DESIGN: Systematic review with meta-analysis. METHODS: A systematic search of Medline, Cinahl, AMED, Web of Science, Scopus, and Embase was conducted up to June 2015. Included studies were controlled trials assessing the effect of an exercise training intervention on cutaneous microvascular reactivity as instigated by local stimulus such as local heating, iontophoresis and post-occlusive reactive hyperaemia...

BACKGROUND: Coronary artery spasm (CAS) is a well-known endothelial dysfunction, and a major cause of vasospastic angina (VSA). The renin-angiotensin system (RAS) is known to be closely associated with endothelial function. However, there are only a few studies that investigated the impact of RAS inhibitor on long-term clinical outcomes in VSA patients. METHODS AND RESULTS: A total of 3349 patients with no significant coronary artery disease, diagnosed with CAS by acetylcholine provocation test were enrolled for this study...

Lumbar sympathectomy was historically a mainstay of treatment for arterial occlusive disease and other vasospastic disorders, before the development of contemporary arterial reconstructive procedures either by surgical or endovascular means. Today, percutaneous methods of sympathetic blockade are possible using chemical neurolytic or ablative modalities. Lumbar sympathetic neurolysis is generally reserved for those patients with ischemic rest pain in the setting of nonreconstructable arterial occlusive disease, although patients with complex regional pain syndrome, peripheral neuralgia, vasospastic disorders, and various other disease states such as plantar hyperhydrosis may also benefit...

OBJECTIVE: To report our preliminary experience with the use of stent retrievers to cause vasodilation in patients with delayed cerebral vasospasm secondary to subarachnoid hemorrhage. METHODS: Four patients from two different high volume neurointerventional centers developed cerebral vasospasm following subarachnoid hemorrhage. In addition to standard techniques for the treatment of cerebral vasospasm, we used commercially available stent retrievers (Solitaire and Capture stent retrievers) to treat the vasospastic segment including M2, M1, A2, and A1...

BACKGROUND: This study aims to determine whether small vessel disease (SVD) or vasospastic disease (VSD) has an impact on prognosis. METHODS: The prospective cohort embraced 718 patients with angina equivalent symptoms and no coronary stenosis ≥50% recruited between 1997 and 2008. At baseline, patients were classified as having SVD, VSD, other cardiac disease or non-cardiac problem based on intracoronary acetylcholine application and fast atrial pacing during coronary angiography...

BACKGROUND: High-dose aspirin has been reported to exacerbate coronary artery spasm in patients with vasospastic angina. We investigated clinical implications of low-dose aspirin on vasospastic angina patients without significant coronary artery stenosis. METHODS: We included patients without significant coronary artery stenosis on coronary angiography (CAG) and with positive results on intracoronary ergonovine provocation test between January 2003 and December 2014...

BACKGROUND: Coronary spasm is one of the mechanisms of myocardial infarction with nonobstructive coronary arteries (MINOCA). The aim of this study was to investigate the effects of aspirin on future cardiovascular events in patients with coronary vasospastic angina (VSA) with non-significant atherosclerotic stenosis. METHODS: This was the retrospective analysis of the 640 VSA patients with non-significant atherosclerotic stenosis (≤50% stenosis) among 1,877 consecutive patients who underwent acetylcholine (ACh)-provocation testing between January 1991 and December 2010...

OBJECTIVES: To evaluate the feasibility of a double-acquisition coronary CT angiography (CCTA) protocol in the presence and absence of an intravenous (IV) vasodilator infusion for detecting vasospastic angina. METHODS: Twenty patients with a high clinical probability of vasospastic angina were enrolled. All subjects underwent baseline CCTA without a vasodilator in the early morning followed by a catheterized coronary angiography with ergonovine provocation test...
