BACKGROUND: Lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic vascular disease. However, there are limited data regarding the impact of Lp(a) levels on the incidence and severity of endothelium-dependent coronary vasomotor response. PATIENTS AND METHODS: A total of 2416 patients without significant coronary artery lesion (<50% stenosis) by coronary angiography and underwent acetylcholine (ACh) provocation test were enrolled and categorized according to their serum Lp(a) level into four quartile groups: less than 6...

A 43-year-old man was diagnosed with acute myocardial infarction (AMI) due to multivessel coronary vasospasm. Accordingly, two coronary vasodilators were administered, and he was discharged without an angina attack. However, from the following day, he reported frequent chest pain and was re-hospitalized. Despite adding multiple coronary vasodilators, it was difficult to completely suppress the angina attack. He also demonstrated hypereosinophilia from the onset of AMI, and his eosinophil count gradually increased up to 6,238 /μL...

This article reports the case of a 22-year-old male patient presented with electrocardiographic ST elevation and elevated cardiac biomarkers. The clinical cascade set into events within an hour of administration of a single-dose of amoxicillin on being diagnosed with acute tonsillitis. The case was preliminarily diagnosed and treated according to the acute coronary syndrome protocol, but on performing coronary angiography no abnormalities in the coronary artery were found. Acute myocarditis was excluded in cardiac MRI...

BACKGROUND: Coronary angiography is performed to assess for obstructive coronary artery disease (CAD), but "nonobstructive CAD" is a common finding. Microvascular or vasospastic angina may be relevant, but routine confirmatory testing is not evidence based and thus rarely performed. AIM: The aim was to assess the effect of stratified medicine guided by coronary function testing on the diagnosis, treatment, and well-being of patients with angina and nonobstructive CAD...

BACKGROUND: Vasospasm is a major cause of morbidity and mortality in patients following aneurysmal subarachnoid hemorrhage (SAH). Although early treatment of ruptured aneurysms is advocated, delayed intervention complicates the treatment strategy and leading to significant vasospasm and a poor prognosis. We report our experience of endovascular protocol for occlusion of the unsecured aneurysm and angioplasty for vasospasm in a single session. METHODS: A total of 24 cases with significant vasospasm and unsecured ruptured cerebral aneurysm were reviewed among 660 aneurysmal SAH patients between January 2011 and May 2017...

Coronary vasospasm is an infrequent cause of acute coronary syndrome. Additionally, femoral artery spasm is not frequently encountered clinically. Here we present a case of a patient with an acute ST segment elevation myocardial infarction, secondary to a documented right coronary artery vasospasm, complicated with left coronary artery and femoral artery vasospasm. Intravenous ultrasound showed calcification at the sites of spasm. This case report indicates that coronary vasospasm should be regularly considered as part of the work up of myocardial infarction...

INTRODUCTION: The classical pathophysiological process underlying acute coronary syndromes has been considered to be plaque rup-ture followed by platelet activation and aggregation and subsequent thrombus formation leading to myocardial ischemia and infarction. A substantial number of patients with acute coronary syndromes appear to have normal or near normal (<50% stenosis) coronary arteries on angiography. Recently, this clinical entity has been coined MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries)...

BACKGROUND: Raynaud's phenomenon (RP) describes the phenomenon of recurrent vasospasm of digital arteries, associated with skin colour changes: pallor, cyanosis and erythema. Twin studies have indicated a genetic predisposition for RP; however, the precise aetiology of RP remains unknown. It is thought that genetic variation in temperature-responsive or vasospastic genes might underlie RP so performed a candidate gene study in a large, population based sample. We assessed the association between RP and single nucleotide polymorphisms (SNPs) in the TRPA1, TRPM8, CALCA, CALCB and NOS1 genes...

INTRODUCTION: Raynaud's disease is characterized by episodic vasospastic attacks and digital ischemia usually followed by pain, numbness and cold. Despite the severity of the symptoms, the investigation of the quality of life in this disease received less attention yet. AIM: The aim of the study was to examine how the disease affects the patients' quality of life. METHOD: Semi-structured interviews were made with 28 patients diagnosed with Raynaud's disease...

It is well known that calcium channel blockers (CCBs) are the first line of therapy for vasospastic angina (VSA). Here, we report two cases of VSA with an increase in the frequency of angina attacks after switching from a brand-name to a generic CCB. In both cases, angina recurred upon switching from a brand-name CCB to a generic CCB during follow-up. The patients' condition improved upon switching back to the original CCB. Both cases involved a high severity of VSA, based on the results of spasm provocation testing...

A 33-year-old man presented with aneurysmal subarachnoid hemorrhage from a ruptured, blister-type sidewall internal carotid artery (ICA) aneurysm. Balloon-assisted coiling was performed with residual neck. He subsequently developed severe vasospasm requiring intra-arterial therapies on multiple occasions, during which it was noted that despite widespread vasospasm, a focal segment of the ICA at the site of the aneurysm showed no significant spasm, suggesting underlying vessel abnormality. He was discharged without deficit and scheduled for flow diversion given concern over this potentially pathologic segment of vessel...

Background: Interferon-free treatment can achieve higher sustained virological response (SVR) rates, even in patients in whom hepatitis C virus (HCV) could not be eradicated in the interferon treatment era. Immune restoration in the liver is occasionally associated with HCV infection. We examined the safety and effects of interferon-free regimens on HCV patients with autoimmune liver diseases. Results: All 7 HCV patients with autoimmune hepatitis (AIH) completed treatment and achieved SVR...

BACKGROUND: Distal transradial access in the anatomical snuffbox has advantages over standard access in terms of patient and operator comfort levels and risk of ischemia. Radial artery preservation could be a relevant issue in patients requiring multiple radial artery procedures and coronary bypass with the use of a radial graft. One relevant drawback is the challenging puncture of a small and weak artery, with a steeper learning curve. AIM: The study was aimed at proving feasibility and safety of right and left transradial access in the anatomical snuffbox...

Raynaud's phenomenon is a vasospastic disorder of the digital vessels triggered by exposure to cold or stress. It is most commonly observed in the hands, but also frequently affects the toes. We present three cases of patients with severe Raynaud's phenomenon in the toes, secondary to scleroderma. The diagnosis of Raynaud's syndrome and scleroderma was established according to the 2010 American College of Rheumatology and European League Against Rheumatism criteria. Patients were treated with 10 units of botulinum toxin injected into each foot...

Vasospastic angina (VSA), also known as variant or Prinzmetal's angina, is a relatively uncommon cause of retrosternal chest pain with transient ST segment elevation, mainly due to vasospasm in the coronary arteries. This is a case of 37-year-old female who presented with chest pain and syncope. Her initial workup, including echocardiogram, was negative. Subsequently, she was sent home with an event monitor. During the next two weeks, she continued to have recurrent episodes of similar chest pains and presented to her cardiology appointment with a heart rate of 45 bpm and blood pressure of 100/60 mmHg and was taken to hospital emergency department...

RATIONALE: Vasospastic angina is caused by sudden occlusive vasoconstriction of a segment of an epicardial artery, with transient ST-segment elevation on electrocardiography. Brugada Syndrome is an inherited arrhythmogenic cardiac disorder with a diagnostic electrocardiography characterized by coved-type ST-segment elevation in right precordial leads (V1-V3). Those two diseases usually have no correlation. In this report, we discuss an interesting case of a patient who was diagnosed as vasospastic angina according to his coronary angiography, but his electrocardiography showed a Brugada-like ST-segment elevation...

BACKGROUND: Kounis syndrome (KS) is the concurrence of acute coronary syndrome associated with mast-cell and platelet activation in the setting of hypersensitivity and allergic or anaphylactic insults. Many drugs and environmental exposures had been reported as inducers, but various inducers and the mechanism of KS remained unknown till now. The widely used traditional Chinese medicine (TCM) as a potential sensitizer were scarcely reported to induce allergic vasospasm due to the ignorance of the linkage between traditional medicine allergy and vasospasm...
