REVIEW
Filippo Crea, Peter Libby
Well into the 21st century, we still triage acute myocardial infarction on the basis of the presence or absence of ST-segment elevation, a century-old technology. Meanwhile, we have learned a great deal about the pathophysiology and mechanisms of acute coronary syndromes (ACS) at the clinical, pathological, cellular, and molecular levels. Contemporary imaging studies have shed new light on the mechanisms of ACS. This review discusses these advances and their implications for clinical management of the ACS for the future...

REVIEW
Shams Y-Hassan, Per Tornvall
Takotsubo syndrome is a recently recognized acute cardiac disease entity with a clinical presentation resembling that of an acute coronary syndrome. The typical takotsubo syndrome patient has a unique circumferential left (bi-) ventricular contraction abnormality profile that extends beyond a coronary artery supply territory and appears to follow the anatomical cardiac sympathetic innervation. The syndrome predominantly affects postmenopausal women and is often preceded by emotional or physical stress. Patients with predisposing factors such as malignancy and other chronic comorbidities are more prone to suffer from takotsubo syndrome...

Coronary artery spasm is involved in the pathogenesis of various cardiac disorders. We investigated patients with a history of syncope who underwent elective coronary angiography. We retrospectively analyzed 5781 consecutive patients who had diagnostic or follow-up angiography during a 26-year period. During this period, we found 95 patients with a history of syncope before elective coronary angiography. Pharmacological spasm provocation testing was performed in 64 patients with a history of syncope (<1 year)...

BACKGROUND: Anaphylaxis is an acute, potentially fatal medical emergency. Myocardial injury or infarction in the setting of an anaphylaxis can be due the anaphylaxis itself, when it is known as Kounis syndrome or it can also be due to the effect of epinephrine treatment. Epinephrine is considered as the cornerstone in management of anaphylaxis. Myocardial infarction secondary to therapeutic doses of adrenaline is a rare occurrence and only a few cases have been reported in literature...

BACKGROUND: The left internal thoracic artery (LITA) is the most commonly used arterial bypass conduit in coronary artery bypass graft (CABG) patients and inadequate LITA flow can result in an increase in morbidity and mortality. In this study, we evaluated the effect of excision of the distal spasmodic segment of the LITA on the free flow in CABG patients. METHODS: This study consisted of 47 patients who underwent elective CABG performed with or without other cardiac surgery, between July 2015 and December 2015...

BACKGROUND: Epicardial adipose tissue (EAT) is the ectopic visceral fat surrounding the heart, which plays an important role in atherosclerosis of the coronary arteries via endothelial damage. Several studies have also suggested that vasospasm with angina (VSA) causes endothelial dysfunction in the coronary arteries. The aim of this study was to evaluate the thickness of EAT in the anterior interventricular groove (EAT-AIG) using echocardiography in patients who had no obstructive coronary artery disease and were suspected of having VSA...

In the clinic, patients with ≥90% luminal narrowing during ergonovine (ER) testing had variable response. We investigated ischemic findings and chest symptoms in patients with ≥90% luminal narrowing when performing ER tests, retrospectively. We performed 1210 ER tests over 26 years (1991-2016). We analyzed chest symptoms and positive ischemic ECG changes during ER tests. More than 90% luminal narrowing was found in 352 patients (29.1%) including 211 patients in the right coronary artery (RCA) and 217 patients in the left coronary artery (LCA)...

Coronary artery vasospasm can cause recurrent anginal episodes with ST-segment elevation. Vasospasm induced myocardial ischemia can lead to arrhythmias including life threatening ventricular tachycardia (VT). Percutaneous coronary intervention (PCI), although not routinely recommended for treating vasospastic angina, can be considered for discrete coronary spasm that is not amenable to vasodilator therapy. We present a challenging case of a 41-year-old lady with recurrent episodes of vasospastic angina and VT refractory to medical therapy, which was successfully treated with PCI and an implantable cardioverter defibrillator...

ST-T segment depression during right-sided endovascular catheter ablation is not only caused by obstructive coronary artery disease or (induced) tachycardia. Clinicians should also consider coronary artery spasms evoked by manipulation of nearby catheters, especially in patients with abnormal coronary artery anatomy.

Epicardial adipose tissue (EAT) represents a cardio-metabolic risk factor; it secretes several adipokines related to coronary atherosclerosis. However, the precise relationship between EAT and coronary vasospasm is unknown. This study aimed to investigate the relationship between EAT and coronary vasospasm using data from the KoRean wOmen'S chest pain rEgistry (koROSE). This study included 551 patients (female/male = 366/185; mean age = 60.2 ± 10.2 years) who presented with chest pain at an outpatient clinic, and who subsequently underwent echocardiography and coronary angiography...

Myocardial infarction commonly occurs due to rupture of atherosclerotic plaque in the coronary arteries and is manifested on coronary angiography. Myocardial infarction with angiographically normal coronary arteries can occur due to hypercoagulable state, coronary spasm, embolism, arteritis, congenital condition and drugs. Illicit drugs such as cocaine, amphetamines and marijuana are known to cause myocardial infarction. Of the many medications that are associated with cardiovascular toxicity, chemotherapeutic agents form a large group with both acute and delayed cardiotoxicity...

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...
