Capecitabine, an oral prodrug of 5-fluorouracil (5-FU), is approved for early-stage and advanced colorectal cancer and metastatic breast cancer. Cardiotoxicity of 5-FU is well described in the literature. However, cardiac adverse effects of capecitabine are poorly described. We report a case of coronary vasospasm induced by capecitabine. A 41-year-old female with metastatic breast cancer presented with chest pain 3 days after starting capecitabine. The chest pain was relieved by rest and exacerbated by exertion...

BACKGROUND: For decades, epidural steroid injections have been an effective tool in the management of many pain related conditions, including lumbar radiculopathy. Transforaminal epidural steroid injections in particular have been reported to potentially result in central nervous system infarctions which have not been reported with interlaminar epidural steroid injections, while providing comparable efficacy. This rare, catastrophic complication has been attributed by some authors to be due to vascular injury secondary to vasospasm, thrombus formation, dissection, as well as concerns with placing the needle at the so-called "safe triangle...

Aneurysmal subarachnoid hemorrhage (SAH) is a devastating disease and nearly one third of patients die in the acute phase. Due to the bleeding event, a hyperactive sympathetic nervous system and an uncontrolled inflammatory response have a profound local and systemic impact on other organ functions. Neuroendocrinological disorders and cardiopulmonary morbidity are dominant. Despite a decrease in hospital mortality for high volume centers, a high proportion of survivors suffer from neurological deficits. Knowledge of the pathophysiology of vasospasms in the later stages of the disease has increased...

Eosinophilic with polyangiitis (EGPA, formerly known as Churg-Strauss syndrome) is a rare systemic disease characterized by a small-vessel necrotizing vasculitis. Cardiac manifestations are broad-ranging and are associated with a poor prognosis. Coronary vasospasm is uncommon.Here, we report a case of an acute coronary vasospasm in a patient with EGPA after corticosteroids withdrawal and nonsteroidal antiinflammatory drug (NSAID) introduction. This patient was initially misdiagnosed as bradykinin-mediated angioedema...

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...

BACKGROUND: Coronary plaques in patients with coronary vasospastic angina have been characterized by diffuse intima-media thickening with homogeneous fibrous tissue, without confluent necrotic tissue. However, coronary vasospasm can trigger coronary thrombosis, and may play an important role in the pathogenesis of acute coronary syndromes, though the precise morphological mechanisms underlying this process remain unclear. CASE PRESENTATION: A 43-year-old man with a history of multivessel coronary vasospastic angina had been treated with long-acting diltiazem and fluvastatin since 2004...

Although delayed cerebral vasospasm (DCV) following subarachnoid hemorrhage (SAH) is closely related to the progression of brain damage, little is known about the molecular mechanism underlying its development. High mobility group box-1 (HMGB1) plays an important role as an initial inflammatory mediator in SAH. In this study, an SAH rat model was employed to evaluate the effects of anti-HMGB1 monoclonal antibody (mAb) on DCV after SAH. A vasoconstriction of the basilar artery (BA) associated with a reduction of nuclear HMGB1 and its translocation in vascular smooth muscle cells were observed in SAH rats, and anti-HMGB1 mAb administration significantly suppressed these effects...

BACKGROUND: Transcranial Doppler (TCD) is endorsed by national guidelines for use in aneurysmal subarachnoid hemorrhage (aSAH) for surveillance of cerebral vasospasm (CV). However, nationwide data on utilization of TCD for CV detection and monitoring in aSAH are lacking. METHODS: Analysis of nationwide trends in TCD prevalence was performed using Nationwide Inpatient Sample (NIS) data from 2002 to 2011. Raw counts were converted into weighted counts, which were used to generate national estimates...

Kounis syndrome is an acute coronary syndrome in the context of a hypersensitivity reaction. The main pathophysiological mechanism appears to be coronary vasospasm. We report the case of a patient with a history of allergy to quinolones, who was given ciprofloxacin before an elective surgical procedure and during drug administration developed symptoms and electrocardiographic changes suggestive of ST-segment elevation acute coronary syndrome. The drug was suspended and coronary angiography excluded epicardial coronary disease...

OBJECTIVES: To determine the causes of software misinterpretation of ST elevation myocardial infarction (STEMI) compared to clinically identified STEMI to identify opportunities to improve prehospital STEMI identification. METHODS: We compared ECGs acquired from July 2011 through June 2012 using the LIFEPAK 15 on adult patients transported by the Los Angeles Fire Department. Cases included patients ≥18 years who received a prehospital ECG. Software interpretation of the ECG (STEMI or not) was compared with data in the regional EMS registry to classify the interpretation as true positive (TP), true negative (TN), false positive (FP), or false negative (FN)...

A 17-year-old male with ADHD who was treated with sertraline and lisdexamfetamine presented with transient episodes of speech impairment and right-sided hemiparesis preceded by headaches. Magnetic resonance imaging revealed three cerebral ischaemic lesions. Treatment was initiated with aspirin and discontinued with lisdexamfetamine. In the literature a causal relationship between treatment with central stimulants and the development of cerebrovascular events has not been substantiated. Vasospasm and paroxystic tachycardia may be associated with the event, but lisdexamfetamine and sertraline cannot be ruled out as risk factors...

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by segmental vasospasm and it is often accompanied by either posterior reversible encephalopathy syndrome or stroke. However, other MRI abnormalities have rarely been reported. A 28-year-old woman presented with a thunderclap headache immediately after delivery; MRI showed segmental vasoconstriction and an abnormal signal in the splenium of the corpus callosum. Neuroimaging abnormalities normalized 20 days after the first examination. Only two cases of RCVS with transient splenial lesions (TSL) have so far been reported...

BACKGROUND: Coronary vasospasm is an important pathogenesis of acute coronary syndrome (ACS). However, the clinical features and prognosis of vasospastic angina (VA) patients presenting with ACS (VAACS) are still unclear. We aimed to evaluate the clinical characteristics and long-term outcomes of VAACS patients without significant coronary artery stenosis. METHODS AND RESULTS: A total of 986 VA patients confirmed by ergonovine provocation test were analyzed. VAACS was defined as VA patients visiting the emergency room with documented electrocardiographic changes, significant arrhythmias, or elevated cardiac biomarkers...

We present a case of imaging proven cerebral vasospasm causing ischemic stroke in a young patient chronically on buprenorphine-naloxone for heroin remission who started smoking cannabis on a daily basis. With cannabis legalization spreading across the states in the USA, it is important for physicians not only to be aware of cannabis reported association with cerebral vasospasm in some patients but also to be on the lookout for possible interacting medications that can synergistically affect cerebral vessels causing debilitating strokes...

BACKGROUND AND PURPOSE: Cerebral infarction after aneurysmal subarachnoid hemorrhage is a significant cause of substantial morbidity and mortality. Because early and delayed cerebral infarction after aneurysmal subarachnoid hemorrhage may be mediated by different processes, we evaluated whether aneurysm-securing methods contributed to infarcts and whether long-term outcomes differ between early and delayed infarcts. METHODS: A post hoc analysis of the CONSCIOUS-1 study (Clazosentan to Overcome Neurological Ischemia and Infarction Occurring After Subarachnoid Hemorrhage) was performed...
