INTRODUCTION: Identifying an Infarct-related artery (IRA)in Non-STEMI is sometimes tricky. Besides, myocardial infarction with non-obstructive coronary arteries (MINOCA) mimickers are often labeled as myocardial infarction. Late Gadolinium enhancement (LGE) on cardiac MRI can help in identifying IRA besides MINOCA mimickers. AIMS: To study the role of LGE on cardiac MRI(CMR) in NSTEMI. MATERIAL METHODS: It was a prospective observational, double-blinded study...

Spontaneous coronary artery dissection (SCAD) is a cause of myocardial infarction without obstructive coronary artery disease (MINOCA). It is determined by a coronary artery wall layers separation, which occurs regardless of traumatic or iatrogenic injuries. Even if it is often a missed diagnosis, its incidence is growing along with the improvement of intracoronary imaging techniques that allow for better detection. The main angiographical classification distinguishes three different forms, with slightly different prognoses at long-term follow up...

KEY CLINICAL MESSAGE: This case underscores the importance of considering myocardial infarction with nonobstructive coronary arteries (MINOCA) in patients experiencing acute chest pain following rabies vaccination, emphasizing the need for heightened awareness and further research into the association between MINOCA and Rabies vaccination. ABSTRACT: Rabies is a vaccine-preventable deadly viral disease prevalent in Asia and Africa that causes thousands of deaths annually...

Energy drinks (EDs) are widely accessible worldwide. In Malaysia, it is common for EDs to be premixed with sexual stimulants. ED consumption has been shown to have an association with cardiac arrest, myocardial infarction, spontaneous coronary artery dissection, and coronary vasospasm. In addition to this, EDs are associated with arrhythmias, which significantly prolong the QTc interval. Myocardial infarction with no obstructive coronary artery disease (MINOCA) is defined as a patient presenting with myocardial infarction with no obstructive coronary artery disease or ≤50% stenosis...

BACKGROUND: Diabetes mellitus is a major cardiovascular risk factor for the development of coronary artery disease, but knowledge about the impact of diabetes mellitus on the outcome of patients with myocardial infarction with non-obstructive coronary arteries is limited. The aim of this study was to investigate the prognostic impact of diabetes mellitus on in- and out-of-hospital adverse events in troponin-positive patients with non-obstructive coronary arteries. METHODS AND RESULTS: A total of 373 troponin-positive patients with non-obstructive coronary arteries between 2010 and 2021 at Bergmannsheil University Hospital Bochum were enrolled, including 65 diabetics and 307 nondiabetics...

AIMS: Coronary artery ectasia (CAE) has been linked to the occurrence of adverse events in patients with ischemia/angina and no obstructive coronary arteries (INOCA/ANOCA), while the relationship between CAE and myocardial infarction with nonobstructive coronary arteries (MINOCA) has been poorly investigated. In our study we aimed at assessing differences in clinical, angiographic and prognostic features among patients with CAE and MINOCA vs. INOCA/ANOCA presentation. METHODS: Patients with angiographic evidence of CAE were enrolled at the University Hospital of Parma and divided into MINOCA vs...

Primary heart tumors are rare, with atrial myxomas being the most common type. Atrial myxomas can lead to embolisms, heart obstruction, and systemic symptoms. Herein, we report a case of 72-year-old woman who presented with a left atrial myxoma at the atrial septal defect occluder, a new acute cerebral infarction, and MINOCA (myocardial infarction with no obstructive coronary atherosclerosis). Left atrial myxoma is a common primary cardiac tumor; however, left atrial myxomas arising after percutaneous atrial septal defect occlusion are rare...

Increasing evidence has shown that coronary spasm and vasomotor dysfunction may be the underlying cause in more than half of myocardial infarctions with non-obstructive coronary arteries (MINOCA) as well as an important cause of chronic chest pain in the outpatient setting. We review the contemporary understanding of coronary spasm and related vasomotor dysfunction of the coronary arteries, the pathophysiology and prognosis, and current and emerging approaches to diagnosis and evidence-based treatment.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a unique disorder that manifests as an acute myocardial infarction clinically without overt coronary arteries obstruction on angiography. Herein, we report a 17-year-old male presented with a chest pain occurring 3 hours before admission and fever lasting for 2 days. Electrocardiogram examination showed ST elevation in lead II, III, aVF and V3-V6. Laboratory tests results showed a normal leukocyte level of 9850/µL, an elevated troponin of 3...

Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) covers an expanding group of patients over recent years. Previous studies showed considerable risks of outcomes in this group. However, there is a lack of evidence in young patients with MINOCA. In this study, we aimed to investigate the long-term outcomes in very young patients with MINOCA. We retrospectively compared the features and predictors of 183 very young (≤40-year-old) patients to >40-year-old patients with MINOCA...

INTRODUCTION AND OBJECTIVE: There is a paucity of data on patients with myocardial infarction with nonobstructive coronary arteries (MINOCA) and a decompensated diabetic state, diabetic ketoacidosis (DKA). Therefore, we aimed to investigate the outcomes of patients with MINOCA presenting with or without DKA. METHODS: We conducted this retrospective propensity score-matched analysis from January 1, 2015, to December 4, 2022. The patients with a principal admission diagnosis of ST-Elevation MI (STEMI) and discharge labeled as MINOCA (ICD-10-CM code 121...

BACKGROUND: Coronary artery disease has a long preclinical phase before manifesting itself clinically due to diffuse non-obstructive disease, stenoses, or thrombosis. CASE SUMMARY: We present a case of a middle-aged male complaining of atypical chest pain, then severe retrosternal pain, and, eventually, effort angina. We performed non-invasive testing, coronary angiography, intravascular imaging, and flow reserve tests, each as appropriate. Cardiovascular risk control, optimization of drug therapy, and percutaneous coronary intervention were considered trying to comply with the best clinical practice...

BACKGROUND: The difference in the long-term outcomes of myocardial infarction in patients with non-obstructed coronary arteries (MINOCA) and patients with myocardial infarction with obstructed coronary artery disease (MI-CAD) is not clear. The current study aimed to pool adjusted data to compare long-term outcomes of MINOCA vs MI-CAD. METHODS: Electronic literature search of PubMed, Embase, CENTRAL, and Google Scholar databases was done for publications up to 18th June 2023...

Cases of patients presenting with myocardial infarction (MI) without angiographic obstructive CAD are not trivial and have significant prevalence. "The Fourth Universal Definition of MI" (4UDMI) published in 2018 introduced MI with non-obstructive coronary arteries (MINOCA). The new section was of great importance as it validated the diagnosis by defining its criteria and recognizing its presence in the community and the need for further investigation. Given the nature of the diagnosis of MINOCA, coronary angiography provides limited information about prognosis and risk stratification for future major adverse cardiovascular events (MACE)...

Myocardial infarction with non-obstructive coronary lesion (MINOCA) represents a non-negligible percentage of the proportion of myocardial infarctions (≈6%). Moreover, the long-term prognosis is poor, with an annual mortality rate of 2%. This high mortality rate may be explained by the fact that MINOCA represents a heterogeneous group, and the diagnosis of pathology is poorly understood. It is essential to be aware of this clinical presentation, and to follow the different diagnostic strategies, in order to identify the etiological mechanism, and thus set up a suitable treatment...

UNLABELLED: The objective of our study was to evaluate the concentrations of pro-inflammatory biomarkers in patients with acute myocardial infarction with non-obstructive coronary arteries (MINOCA) compared to patients with acute myocardial infarction with obstructive coronary arteries (MI-CAD) in the early post-infarction period and after 1 year and to perform a comparative analysis of the relationship between laboratory biomarkers and atherosclerosis progression in patients with MINOCA and MI-CAD...

UNLABELLED: Myocardial bridging (MB) is a congenital anomaly characterized by the intramyocardial coronary course that can cause coronary compression during systole leading to myocardial ischemia, often with the concomitant presence of endothelial dysfunction.Improvements in computed tomography (CT) technology have increased the burden of MB detection during coronary-CT (cCT) but their anatomical and functional assessment is often challenging. A stress-rest myocardial perfusion imaging (MPI) by single-photon emission CT (SPECT) is usually required to decide the correct patient management...

Spontaneous coronary artery dissection (SCAD), although in the majority of cases presents as an acute coronary syndrome (ACS), has different pathophysiology from atherosclerosis that influences specific angiography findings and enables most patients to be solved by optimal medical therapy rather than percutaneous coronary intervention (PCI). Therefore, accurate diagnosis is essential for adequate treatment of each patient as management of SCAD differs from that of ACS of atherosclerotic aetiology. So far, invasive coronary angiography remains the most important diagnostic tool in suspected SCAD...

Myocardial infarction with nonobstructive coronary arteries (MINOCA) has several possible underlying causes, including coronary microvascular dysfunction (CMD). Early cardiovascular magnetic resonance imaging (CMR) is recommended, however cannot provide a diagnosis in 25% of cases. Quantitative stress CMR perfusion mapping can identify CMD, however it is unknown if CMD is present during long-term follow-up of MINOCA patients. Therefore, this study aimed to evaluate presence of CMD during long-term follow-up in MINOCA patients with an initial normal CMR scan...
