BACKGROUND: Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a known clinical conundrum with limited investigation. Using a large population-based cohort, we examined the incidence, demographic profile, use of evidence-based medicines (EBM) and clinical outcomes of MINOCA patients. METHODS: Patients hospitalized with a primary diagnosis of MI who underwent coronary angiography between 01/04/2002 and 31/03/2014 in Alberta, Canada, were included in the study...

BACKGROUND: Myocardial infarction (MI) with nonobstructive coronary arteries (MINOCA) is a heterogeneous entity often overlooked in contemporary medicine. We aim to determine MINOCA differential characteristics, the main etiologies, and prognostic outcomes. PATIENTS AND METHODS: We carried out a retrospective longitudinal analysis including 1047 patients with MI, from 1 January 2011 to 1 January 2016, subjected to coronary angiography and classified according to the presence [MI and obstructive coronary artery disease (MICAD)] or absence (MINOCA) of any coronary stenosis of at least 50%...

BACKGROUND: Premature myocardial infarction (MI) is an increasingly prevalent cause of morbidity and mortality worldwide. A subset of patients, predominantly young women, present with MI with no obstructive coronary artery disease (MINOCA), a nomenclature gaining recognition. However, few data exist on presentation and prognosis according to the severity of coronary artery disease (CAD). METHODS: We studied patients with premature (younger than 55 years of age) acute MI enrolled in a large cohort in 24 centres across Canada...

BACKGROUND: Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCAs) is an increasingly recognized entity. No previous study has evaluated predictors for new major adverse cardiacvascular events (MACEs) and death in patients with MINOCA. METHODS: We conducted an observational study of MINOCA patients recorded between July 2003 and June 2013 and followed until December 2013 for outcome events. Out of 199,163 MI admissions, 9092 consecutive unique patients with MINOCA were identified...

The syndromes of myocardial infarction/myocardial ischemia with No Obstructive Coronary Artery Disease (MINOCA/INOCA) are increasingly evident. A majority of these patients have coronary microvascular dysfunction. These patients have elevated risk for a cardiovascular event (including acute coronary syndrome, myocardial infarction, stroke, and repeated cardiovascular procedures) and appear to be at higher risk for development of heart failure with preserved ejection fraction. Terminology such as coronary artery disease or coronary heart disease is often synonymous with obstructive atherosclerosis in the clinician's mind, leaving one at a loss to recognize or explain the phenomenon of MINOCA and INOCA with elevated risk...

Sandrine Lebrun, Rachel M Bond
Coronary heart disease (CHD) continues to be understudied, underdiagnosed, and undertreated in women. Gender and age bias complicate the evaluation of women with acute coronary syndrome (ACS). As a result, conditions like spontaneous coronary artery dissection (SCAD) are often missed. SCAD is an infrequent yet important cause of myocardial infarction (MI) with a predilection for young to middle aged women. The condition is thought to be under-reported, likely a result of both low index of suspicion as well as an unfamiliarity with SCAD's angiographic variants...

BACKGROUND: Sex differences in early mortality after myocardial infarction (MI) vary by age. MI with nonobstructive coronary arteries (MINOCA [<50% stenosis]) is more common among younger patients and women, and MINOCA has a better prognosis than MI with obstructive coronary artery disease (MI-CAD). The relationship between age, sex, and obstructive CAD status and outcomes post-MI has not been established. METHODS AND RESULTS: Adults who underwent coronary angiography for acute ST-segment-elevation and non-ST-segment-elevation MI in the National Cardiovascular Data Registry ACTION Registry-GWTG (Acute Coronary Treatment and Intervention Outcomes Network Registry-Get With the Guidelines) from 2007 to 2014 were identified...

BACKGROUND: There is an emerging field underlying the myocardial infarction (MI) with non-obstruc-tive coronary arteries (MINOCA). The aim of this study was to evaluate the impact of psycho-emotional disorders and social habits in MINOCA patients. METHODS: The study included 95 consecutive patients diagnosed of MINOCA and 178 patients with MI and obstructive lesions. MINOCA patients were included when they fulfilled the three main criteria: accomplishment of the Third Universal Definition of Myocardial Infarction, absence of obstructive coronary arteries and no clinically overt specific cause for the acute presentation...

Aims: Functional alterations of epicardial coronary arteries or coronary microcirculation represent a frequent cause of myocardial infarction and non-obstructive coronary arteries (MINOCA). We aimed at assessing the prognostic value of intracoronary provocative tests in patients presenting with MINOCA and in which other causes of MINOCA have been excluded. Methods and results: We prospectively evaluated patients with a diagnosis of MINOCA, excluding patients with aetiologies other than suspected coronary vasomotor abnormalities...

This article gives an update on the management of acute ST-segment elevation myocardial infarction (STEMI) according to the recently released European Society of Cardiology guidelines 2017 and the modifications are compared to the previous STEMI guidelines from 2012. Primary percutaneous coronary intervention (PCI) remains the preferred reperfusion strategy. New guideline recommendations relate to the access site with a clear preference for the radial artery, use of drug-eluting stents over bare metal stents, complete revascularization during the index hospitalization, and avoidance of routine thrombus aspiration...

BACKGROUND: Myocardial Infarction with Non-Obstructive Coronary Arteries (MINOCA) is common with a prevalence of 6% of all patients fulfilling the diagnosis of myocardial infarction. MINOCA should be considered a working diagnosis. Cardiac Magnetic Resonance (CMR) imaging has recently been suggested to be of great value to determine the cause behind MINOCA. The objectives of this paper are to describe the rationale behind the second Stockholm Myocardial Infarction with Normal Coronaries (SMINC-2) study and to discuss the protocol for investigation of MINOCA patients in the light of the recently published position paper from the European Society of Cardiology...

Patients with myocardial infarction with nonobstructive coronary arteries (MINOCA), including Takotsubo syndrome (TS), are considered to have a better survival compared with those with coronary heart disease (CHD). Studies of patients with MINOCA measuring physical and mental function including matched control groups are lacking. The aim of this study was to determine the physical capacity and quality of life in patients with MINOCA. One-hundred patients with MINOCA along with TS (25%) were investigated from 2007 to 2011...

AIM: To assess the arrhythmic determinants and prognosis of patients presenting with myocardial infarction and non-obstructive coronary arteries (MINOCA) with normal ejection fraction (EF). METHODS: This is an observational analysis of 131 MINOCA patients with normal EF. Three cardiac magnetic resonance (CMR) diagnosis classes were recognized according to the late gadolinium enhancement (LGE) pattern: Myocardial infarction (MI) (n = 34), myocarditis (n = 47), and "no LGE" (n = 50)...

BACKGROUND: Myocardial infarction with nonobstructive coronary arteries (MINOCA) occurs in 5% to 10% of all patients with myocardial infarction. Clinical trials of secondary prevention treatment in MINOCA patients are lacking. Therefore, the aim of this study was to examine the associations between treatment with statins, renin-angiotensin system blockers, β-blockers, dual antiplatelet therapy, and long-term cardiovascular events. METHODS: This is an observational study of MINOCA patients recorded in the SWEDEHEART registry (the Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapy) between July 2003 and June 2013 and followed until December 2013 for outcome events in the Swedish Cause of Death Register and National Patient Register...

MINOCA is a clinical syndrome that encompasses a subgroup of heterogeneous patients who present with myocardial infarction yet do not have any significant coronary artery obstruction on angiogram. As many as one in ten patients with acute myocardial infarction (AMI) will not have an occluded coronary artery, and the reported prevalence keeps rising, in part due to better recognition of this syndrome. Current guidelines offer several diagnostic algorithms but MINOCA remains largely under-recognised and little is known about whether patients might benefit from a more specific treatment modality...

BACKGROUND: In a prospective study, cardiac MRI (CMR) and intravascular ultrasound were performed in women with myocardial infarction (MI) and nonobstructive coronary artery disease (MINOCA). Forty participants underwent adenosine-stress CMR (sCMR). HYPOTHESIS: Abnormal perfusion may co-localize with ischemic late gadolinium enhancement (LGE) and T2-weighted signal hyperintensity (T2+), suggesting microvascular dysfunction contributed to MI. METHODS: Qualitative perfusion analysis was performed by 2 independent readers...

BACKGROUND: Coronary spasm is one of the mechanisms of myocardial infarction with nonobstructive coronary arteries (MINOCA). The aim of this study was to investigate the effects of aspirin on future cardiovascular events in patients with coronary vasospastic angina (VSA) with non-significant atherosclerotic stenosis. METHODS: This was the retrospective analysis of the 640 VSA patients with non-significant atherosclerotic stenosis (≤50% stenosis) among 1,877 consecutive patients who underwent acetylcholine (ACh)-provocation testing between January 1991 and December 2010...

INTRODUCTION: Coronary angiography is commonly performed following non-ST segment elevation myocardial infarction (NSTEMI) to assess the need for revascularization. Some of these patients have myocardial infarction (MI) with no obstructive coronary atherosclerosis (MINOCA). Patients without severe obstructive lesions are usually treated conservatively. However, coronary angiography has known limitations in the assessment of lesion severity. We report our experience of using coronary Optical Coherence Tomography (OCT) in a series of patients without severe obstructive coronary lesions...
