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...

BACKGROUND: Myocardial bridge (MB) has been reported to induce cardiac complications including coronary vasospasm. Although MB has some anatomical and morphological variations, the association of these variations with vasospasm is unclear. The aim of this study was to investigate the relation between morphological severity of MB and vasospasm induced by acetylcholine (ACh) provocation test. METHODS: A total of 392 patients without coronary stent in the left anterior descending artery (LAD) undergoing intracoronary ACh provocation test were included...

Myocardial infarction (MI) is an extremely common cause of chest pain. MI can be acute with ST elevation (STEMI) or non-STEMI (NSTEMI). Coronary artery spasm can be severe enough to cause occlusion of the coronary arteries particularly with an exaggerated response in regions of coronary atheroma and plaque ulceration. It is not uncommon for coronary spasm to be mistaken with acute thrombotic occlusion of the coronary artery. We describe a case of a 42-year old man with known cardiac risk factors presents with chest pain for few hours to a tertiary centre hospital...

BACKGROUND: The uptake of percutaneous coronary procedures via the radial artery has increased internationally due to the decreased risk of complications and increased patient satisfaction. The increased susceptibility of the radial artery to spasm however presents a potential risk for procedural failure. Although most experts agree on the need for prophylactic medications to reduce radial artery spasm, currently there is inconsistency in literature regarding the most effective vasodilatory medication or combination of medications...

Guidewire-induced pseudo-lesions are referred to accordion phenomenon and are infrequent occurrences during percutaneous coronary intervention of tortuous coronary arteries. Their occurrence can be a diagnostic challenge to the interventionist and might lead to unnecessary intervention. Ischemia and hemodynamic compromise are possible complications, if not managed promptly. The differential diagnosis includes coronary dissection, thrombus, and spasm. We describe a patient who developed pseudo-lesions of the tortuous right coronary artery in multiple segments during PCI...

We present a case of a 47-year-old woman with a mechanical mitral valve prosthesis and recurrent myocardial infarction. The most common etiology of spontaneous myocardial infarction is an acute coronary syndrome caused by rupture or erosion of an atherosclerotic plaque. However, the differential diagnosis in the patient described below also included infarction due to embolization or coronary spasm. It can be challenging to discriminate between the different causes of myocardial infarction based on interpretation of symptoms, physical examination, laboratory tests, and electrocardiography alone...

OBJECTIVE: This prospective study assesses balloon-assisted tracking (BAT) in reducing radial access failure during percutaneous coronary intervention (PCI). BACKGROUND: Arterial spasm prevents PCI from the radial artery in a small percentage of cases. METHODS: A total of 2223 consecutive patients undergoing PCI from the radial approach were analyzed. Radial access failure mode and requirement for crossover to femoral access during a 12-month run-in period were compared with the following 14-month period with routine BAT usage...

RATIONALE: Coronary artery spasm (CAS) could cause serious lethal ventricular arrhythmias. While implantable cardioverter defibrillators (ICDs) have been recommend for secondary prevention of sudden cardiac death related to lethal ventricular arrhythmias. However, in resuscitated sudden cardiac death caused by CAS, the effect of ICD is still not well clear. PATIENT CONCERNS: A 60-year-old male presented with 2 episodes of syncope. Coronary angiography showed normal coronary arteries...

OBJECTIVE: The aim of the present study was to assess the level of access site pain in patients undergoing transradial coronary catheterization by using topical application of an anesthetic ointment (lidocaine/prilocaine-AO) compared to standard local anesthesia (LA) by means of injectable lidocaine. METHODS: We prospectively studied 444 patients undergoing elective trans-radial coronary angiography. The quality of analgesia was assessed using a visual analogue scale (VAS) immediately after the puncture and 30 min after the removal of the sheath...

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.

George Kassimis, George Krasopoulos
Intraoperative Transit Time Flowmetry is currently recommended to assess graft patency during coronary artery bypass grafting (CABG), especially in presence of haemodynamic instability or inability to wean the patient from cardiopulmonary bypass, new regional wall motion abnormalities, or significant ventricular arrhythmias. The VeriQ™ system is one of the currently available systems, which detects imperfections that may be corrected by graft revision. In this case report, multivessel coronary spasm (CS) post-CABG interferes with these intraoperative parameters misleading initially into false results...

AIMS: Systematic review of literature to evaluate safety of intracoronary (i.c.) pharmacologic testing with acetylcholine (ACh), or ergonovine (ERGO), to induce coronary artery spasm. METHODS AND RESULTS: Review of all relevant publications using MEDLINE and EMBASE databases yielded 10 publications, totalling 9,444 patients. Prevalence of provoked spasm varied from 2.3% to 54.7% of patients tested in the selected studies. The wide variability in prevalence was due to heterogeneity of study populations and provocation protocols...

BACKGROUND: Categorization as a cytochrome P450 (CYP) 2C19 poor metabolizer (PM) is reported to be an independent risk factor for cardiovascular disease. Epoxyeicosatrienoic acids (EETs) are metabolites of arachidonic acid by CYP2C19 epoxygenases and anti-inflammatory properties, especially in microvascular tissues. We examined the impact of CYP2C19 polymorphisms and EETs on the patients with microvascular angina (MVA) caused by coronary microvascular dysfunction. METHODS AND RESULTS: We examined CYP2C19 genotypes in patients with MVA (n = 81)...

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...

REVIEW
Francesco Pelliccia, Juan Carlos Kaski, Filippo Crea, Paolo G Camici
Originally described by Japanese authors in the 1990s, Takotsubo syndrome (TTS) generally presents as an acute myocardial infarction characterized by severe left ventricular dysfunction. TTS, however, differs from an acute coronary syndrome because patients have generally a normal coronary angiogram and left ventricular dysfunction, which extends beyond the territory subtended by a single coronary artery and recovers within days or weeks. The prognosis was initially thought to be benign, but subsequent studies have demonstrated that both short-term mortality and long-term mortality are higher than previously recognized...

BACKGROUND: Carfilzomib (CFZ) is a new proteasome inhibitor used for the treatment of multiple myeloma. Besides heart failure, angina and myocardial ischemia occurred following administration of CFZ, which is not contraindicated in patients with recent myocardial infarction/unstable angina excluded from the safety trials. AIM OF STUDY: To test the effects of CFZ (10(-9) to 10(-7)mol/L) on vascular tone and reactivity in the isolated rabbit heart and aorta. METHODS AND RESULTS: CFZ administered by bolus injection to the isolated heart increased coronary perfusion pressure (CPP) at all tested concentrations and mildly raised left ventricular pressure and heart rate, only at the highest concentration...
