Raynaud's phenomenon (RP) is a vasospastic disorder characterized by recurrent self-limited episodes of skin pallor, cyanosis, and hyperemia caused by paroxysmal spasms in the small arteries of the fingers and toes and can occur in any age group. Hands, feet, nose, ears, and nipples can be affected. The diagnosis is made clinically, assessing varying degrees of ischemia in the involved areas of skin, but this transient ischemia may also herald the onset of connective tissue disease. Investigation is recommended when RP starts in childhood to exclude an underlying autoimmune condition and close follow-up for its development...

A 41-year-old woman presented with central chest discomfort. She had been previously well, was an ex-smoker and reported no regular medication. The ECG developed T-wave changes inferiorly and anterolaterally and troponin I concentrations were elevated confirming non-ST elevation myocardial infarction. Cardiac catheterization showed severe spasm of the right and left anterior descending coronary arteries which resolved with intracoronary nitrates. She later volunteered that prior to presentation she had been taking non-prescription Acti-Phen a slimming agent containing phentermine...

Vasospastic transient monocular vision loss associated with systemic lupus erythematosus and antiphospholipid syndrome is typically short lasting and responsive to vasodilators. Virchow's triad of endothelial dysfunction, arterial stasis, and a hypercoagulable state are factors in systemic lupus erythematosus/antiphospholipid syndrome that may potentially contribute to prolonged retinal hypoperfusion and central retinal artery occlusion. Consequently, rapid intervention to address all components of Virchow's triad may increase the probability of a good outcome...

Pharmacologic efforts to improve outcomes following aneurysmal subarachnoid hemorrhage (aSAH) remain disappointing, likely owing to the complex nature of post-hemorrhage brain injury. Previous work suggests that heparin, due to the multimodal nature of its actions, reduces the incidence of clinical vasospasm and delayed cerebral ischemia that accompany the disease. This narrative review examines how heparin may mitigate the non-vasospastic pathological aspects of aSAH, particularly those related to neuroinflammation...

A 52-year-old man complaining of persistent recurring chest pain at night underwent coronary angiogram at another institution. Normal coronaries were observed and he was discharged with muscle spasmolytic prescription. Since symptoms had continued, 24-hour Holter monitoring was ordered at our facility and results revealed huge ST elevation and polymorphic ventricular tachycardia. Cold pressor test performed in catheterization laboratory also resulted in ventricular tachycardia. Nifedipine was prescribed and follow-up Holter monitoring revealed no further vasospastic episodes...

Although coronary obstruction due to atherosclerosis is the most common cause of myocardial ischemia, a significant proportion of patients have myocardial ischemia in the absence of obstructive epicardial coronary artery disease (CAD). This finding is more common among women and alternative causes can mediate myocardial ischemia. Abnormalities in vascular structure, alterations in coronary vasomotion and dysfunction of the coronary microcirculation can all cause ischemia in the absence of obstructive CAD due to atherosclerosis...

The spasm provocation test (SPT) is an important test in the diagnosis of vasospastic angina (VSA). In many cases, this test is performed as the gold standard test, and VSA is considered not present if the SPT is negative. However, some patients continue to experience chest symptoms despite a negative SPT. In this study, we report four cases in which SPT was repeated to evaluate chest symptoms despite the negative results of the first SPT. Two men in their 70s, one woman in her 60s, and one woman in her 70s, all with chest symptoms, underwent a second SPT at 4, 3, 2, and 3 years, respectively, after the first SPT, which was negative...

Kounis syndrome is defined as the coincidental occurrence of an acute coronary syndrome with hypersensitivity reactions following an allergic event. The three reported variants of Kounis syndrome are vasospastic allergic angina, allergic myocardial infarction and stent thrombosis with occluding thrombus. The syndrome is caused by various inflammatory mediators. The pathophysiological characteristics of Kounis syndrome involve coronary artery spasm and/or atheromatous plaque erosion or rupture during an allergic reaction...

INTRODUCTION: Non-freezing cold injury (NFCI) remains largely under-reported, and is of particular importance in the armed forces where its prevalence is greatest. Iloprost, a synthetic prostaglandin I2 analogue, has previously been used with some success in the treatment of vasospastic and freezing cold injuries, although its role in NFCI remains unclear. CASE REPORT: An Iloprost infusion was used to treat the long-term sequelae of an ex-soldier suffering with ongoing pedal pain and loss of function 20 years after the initial NFCI insult sustained on military exercise...

RATIONALE: ST-segment elevation localizes an ischemic lesion to the coronary artery supplying the area of the myocardium reflected by the electrocardiographic leads. Dynamic ST-segment elevation can be due to severe transmural ischemia secondary to a thrombus, vasospasm, or a tightly fixed coronary artery lesion or a combination of these situations. PATIENT CONCERNS: In this study, we report on two patients with angina who had fluctuations in ST-segment amplitude on serial electrocardiograms...

Several chemotherapeutic agents are known to be cardiotoxic. One of them, 5-fluorouracil (5-FU), has been associated with coronary ischemia and reversible vasospasm. In this report, we describe a 54-year-old man with rectal cancer who developed chest pain during 5-FU infusion. His initial electrocardiogram (ECG), obtained while he was experiencing chest pain, showed hyperacute T waves in the anterolateral leads. Those waves disappeared along with the chest pain after administration of sublingual nitroglycerine...

BACKGROUND: When drug-induced coronary spasm provocation tests are performed, a washout period of >48h for calcium channel blockers (CCBs) is uniformly recommended. However, each CCB has a distinct half-life, and little is known about the influence of prior oral administration of CCBs on acetylcholine provocation test to evaluate coronary vasomotor reaction. METHODS AND RESULTS: We examined 245 consecutive patients with suspected vasospastic angina who had undergone acetylcholine provocation test...

BACKGROUND: Early diagnosis of vasospasm following subarachnoid hemorrhage can prevent cerebral ischemia and improve neurological outcomes. This study numerically evaluates the relevance of extracranial blood velocity indices to detect vasospasm. METHODS: A numerical model of cerebral blood flow was used to evaluate the hemodynamics associated with anterior and posterior vasospasm under normal and impaired cerebral autoregulation conditions. Extracranial blood velocities at the carotid and vertebral arteries and their ratios between ipsilateral and contralateral, anterior and posterior, and downstream and upstream arteries were monitored during vasospasm progression...

Kounis syndrome (KS) is a hypersensitivity coronary disorder induced by exposure to drugs, food, environmental and other triggers. Vasospastic allergic angina, allergic myocardial infarction (MI) and stent thrombosis with occluding thrombus infiltrated by eosinophils and/or mast cells constitute the three main variants of this syndrome. We reviewed 175 patients who fulfilled the definition of one of the three types of KS. The epidemiology, diagnostic findings, management and complications were reviewed in this article...

Though cardioprotective, niacin monotherapy is limited by unpleasant cutaneous symptoms mimicking dermatitis: niacin-associated skin toxicity (NASTy). Niacin is prototypical of several emerging drugs suffering off-target rubefacient properties whereby agonizing the GPR109A receptor on cutaneous immune cells provokes vasodilation, prompting skin plethora and rubor, as well as dolor, tumor, and calor, and systemically, heat loss, frigor, chills, and rigors. Typically, NASTy effects are described by subjective patient-reported perception, at best semi-quantitative and bias-prone...

BACKGROUND: There is little information about the relationship between J waves and the occurrence of ventricular fibrillation (VF) in patients with vasospastic angina (VSA). The present study aimed to assess the incidence of J waves and the occurrence of VF in patients with VSA. METHODS: The subjects consisted of 62 patients with VSA diagnosed by acetylcholine provocation tests in our institution from 2002 to 2014. We investigated the VF events, prevalence of J waves, and relationship between the VF events and J waves...
