Background: The left atrial volume (LAV) is a crucial cardiac parameter in several clinical settings such as in atrial fibrillation or heart failure for the assessment of diastolic dysfunction and cardiac risk. Currently available LAV reference values were defined by 2d transthoracic echocardiography (2d-TTE). However, LAV measurements are routine part of CMR protocols, though data on the interchangeability of LAV values between CMR and 2d-TTE remain scarce.Methods: We performed CMR (3 T scanner MAGNETOM™ Skyra, Siemens Healthineers, Erlangen, Germany) and 2d-TTE in 2126 participants of the Hamburg City Health Study (HCHS), a population-based cohort study of the middle-aged population in Hamburg. LAV was assessed in TTE from the 4-and 2-chamber view by the method of disk summation. In CMR, LAV was also measured in cine images from the 2-and 4-chamber orientation, employing the …

Background Women are overrepresented among individuals with post-acute sequelae of SARS-CoV-2 infection (PASC). Biological (sex) as well as sociocultural (gender) differences between women and men might account for this imbalance, yet their impact on PASC is unknown. Aim We assessed the impact of sex and gender on PASC in a Swiss population. Method Our multicentre prospective cohort study included 2,856 (46% women, mean age 44.2 ± 16.8 years) outpatients and hospitalised patients with PCR-confirmed SARS-CoV-2 infection. Results Among those who remained outpatients during their first infection, women reported persisting symptoms more often than men (40.5% vs 25.5% of men; p < 0.001). This sex difference was absent in hospitalised patients. In a crude analysis, both female biological sex (RR = 1.59; 95% CI: 1.41–1.79; p < 0.001) and a score summarising gendered sociocultural …

Desmoglein-2 mutations are detected in 5–10% of patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). Endurance training accelerates the development of the ARVC phenotype, leading to earlier arrhythmic events. Homozygous Dsg2 mutant mice develop a severe ARVC-like phenotype. The phenotype of heterozygous mutant (Dsg2mt/wt) or haploinsufficient (Dsg20/wt) mice is still not well understood. To assess the effects of age and endurance swim training, we studied cardiac morphology and function in sedentary one-year-old Dsg2mt/wt and Dsg20/wt mice and in young Dsg2mt/wt mice exposed to endurance swim training. Cardiac structure was only occasionally affected in aged Dsg20/wt and Dsg2mt/wt mice manifesting as small fibrotic foci and displacement of Connexin 43. Endurance swim training increased the right ventricular (RV) diameter and decreased RV function in Dsg2mt/wt mice but not in wild types. Dsg2mt/wt hearts showed increased ventricular activation times and pacing-induced ventricular arrhythmia without obvious fibrosis or inflammation. Preload-reducing therapy during training prevented RV enlargement and alleviated the electrophysiological phenotype. Taken together, endurance swim training induced features of ARVC in young adult Dsg2mt/wt mice. Prolonged ventricular activation times in the hearts of trained Dsg2mt/wt mice are therefore a potential mechanism for increased arrhythmia risk. Preload-reducing therapy prevented training-induced ARVC phenotype pointing to beneficial treatment options in human patients.

Aims Recent trial data demonstrate beneficial effects of active rhythm management in patients with atrial fibrillation (AF) and support the concept that a low arrhythmia burden is associated with a low risk of AF-related complications. The aim of this document is to summarize the key outcomes of the 9th AFNET/EHRA Consensus Conference of the Atrial Fibrillation NETwork (AFNET) and the European Heart Rhythm Association (EHRA). Methods and results Eighty-three international experts met in Münster for 2 days in September 2023. Key findings are as follows: (i) Active rhythm management should be part of the default initial treatment for all suitable patients with AF. (ii) Patients with device-detected AF have a low burden of AF and a low risk of stroke. Anticoagulation prevents some strokes and also increases major but non-lethal bleeding. (iii) More research is needed to …

Background Among low-risk patients with severe, symptomatic aortic stenosis who are eligible for both transcatheter aortic-valve implantation (TAVI) and surgical aortic-valve replacement (SAVR), data are lacking on the appropriate treatment strategy in routine clinical practice. Methods In this randomized noninferiority trial conducted at 38 sites in Germany, we assigned patients with severe aortic stenosis who were at low or intermediate surgical risk to undergo either TAVI or SAVR. Percutaneous- and surgical-valve prostheses were selected according to operator discretion. The primary outcome was a composite of death from any cause or fatal or nonfatal stroke at 1 year. Results A total of 1414 patients underwent randomization (701 to the TAVI group and 713 to the SAVR group). The mean (±SD) age of the patients was 74±4 years; 57% were men, and the median Society of Thoracic Surgeons risk score was …

Introduction Fabry's disease is an X-linked lysosomal storage disorder caused by reduced activity of α-galactosidase A (GAL), leading to premature death on account of renal, cardiac, and vascular organ failure. Accumulation of the GAL substrate globotriaosylceramide (Gb3) in endothelial and smooth muscle cells is associated with early vascular cell damage, suggesting endothelial dysfunction as a driver of cardiorenal organ failure. Here, we studied the vascular expression of the key angiogenic factors, VEGFα and its antagonist angiostatin, in Fabry α-GAL-Tg/KO mice and determined circulating VEGFα and angiostatin serum levels in patients with Fabry’s disease and healthy controls. Methods Cryopreserved aortic vessels from six α-GAL-Tg/KO and six wild-type (WT) mice were obtained and VEGFα and angiostatin levels were determined by performing Western blot analysis. VEGFα expression was visualized by an immunohistochemical staining of paraffin aortic rings. In addition, VEGFα and angiostatin serum levels were measured by using an enzyme-linked immunosorbent assay in 48 patients with genetically verified Fabry's disease (50% male) and 22 healthy controls and correlated with disease severity markers such as lyso-Gb3, albuminuria, NTproBNP, high-sensitive troponin T (hsTNT), and myocardial wall thickness. Results It was found that there was a significant increase in VEGFα protein expression (1.66 ± 0.35 vs. 0.62 ± 0.16, p = 0.0009) and a decrease in angiostatin expression (0.024 ± 0.007 vs. 0.053 ± 0.02, p = 0.038) in aortic lysates from α-GAL-Tg/KO compared with that from WT mice.

Viral myocarditis is characterized by infiltration of mononuclear cells essential for virus elimination. GPR15 has been identified as a homing receptor for regulatory T cells in inflammatory intestine diseases, but its role in inflammatory heart diseases is still elusive. Here we show that GPR15 deficiency impairs coxsackievirus B3 elimination, leading to adverse cardiac remodeling and dysfunction. Delayed recruitment of regulatory T cells in GPR15-deficient mice was accompanied by prolonged persistence of cytotoxic and regulatory T cells. In addition, RNA sequencing revealed prolonged inflammatory response and altered chemotaxis in knockout mice. In line, we identified GPR15 and its ligand GPR15L as an important chemokine receptor–ligand pair for the recruitment of regulatory and cytotoxic T cells. In summary, the insufficient virus elimination might be caused by a delayed recruitment of T cells as well as …

Background Atrial fibrillation (AF) and concomitant cardiometabolic disease processes interact and combine to lead to adverse events such as stroke, heart failure, myocardial infarction, and cardiovascular death. Circulating biomolecules provide quantifiable proxies for cardiometabolic disease processes. Their role in defining subphenotypes of AF is not known. Methods and results This prespecified analysis of the EAST-AFNET4 biomolecule study assigned patients to clusters using polytomous variable latent class analysis (poLCA) based on baseline concentrations of thirteen precisely-quantified biomolecules potentially reflecting ageing, cardiac fibrosis, metabolic dysfunction, oxidative stress, cardiac load, endothelial dysfunction, and inflammation. In each cluster, rates of cardiovascular death, stroke, or hospitalization for heart failure or acute coronary syndrome, the primary …

BACKGROUND SGLT2 (sodium-glucose cotransporter 2) inhibitors (SGLT2i) can protect the kidneys and heart, but the underlying mechanism remains poorly understood. METHODS To gain insights on primary effects of SGLT2i that are not confounded by pathophysiologic processes or are secondary to improvement by SGLT2i, we performed an in-depth proteomics, phosphoproteomics, and metabolomics analysis by integrating signatures from multiple metabolic organs and body fluids after 1 week of SGLT2i treatment of nondiabetic as well as diabetic mice with early and uncomplicated hyperglycemia. RESULTS Kidneys of nondiabetic mice reacted most strongly to SGLT2i in terms of proteomic reconfiguration, including evidence for less early proximal tubule glucotoxicity and a broad downregulation of the apical uptake transport machinery (including sodium, glucose, urate, purine bases, and amino acids …

Atrial fibrillation is one of the most common cardiac arrhythmias and is a major cause of ischaemic stroke. Recent findings indicate the importance of atrial fibrillation burden (device-detected, subclinical, or paroxysmal and persistent or permanent) and whether atrial fibrillation was known before stroke onset or diagnosed after stroke for the risk of recurrence. Secondary prevention in patients with atrial fibrillation and stroke aims to reduce the risk of recurrent ischaemic stroke. Findings from randomised controlled trials assessing the optimal timing to introduce direct oral anticoagulant therapy after a stroke show that early start (ie, within 48 h for minor to moderate strokes and within 4–5 days for large strokes) seems safe and could reduce the risk of early recurrence. Other promising developments regarding early rhythm control, left atrial appendage occlusion, and novel factor XI inhibitor oral anticoagulants suggest …

Background Direct, non-vitamin K antagonist oral anticoagulants (DOACs/NOACs) have become the first-choice therapy for stroke prevention in patients with atrial fibrillation (AF) at risk of stroke. Data on long-term effectiveness and safety of NOACs are scarce and not available from randomised clinical trials. Purpose We analysed 4-year outcome data in 13,632 European patients with AF treated with the NOAC, edoxaban. Methods This is the first report of the four-year follow-up information collected in the ETNA-AF-Europe (NCT02944019) study. It is a prospective registry, conducted in 825 centres enrolling edoxaban-treated patients in 10 European countries. Design and follow-up were agreed with the European Medicines Agency as part of the post-approval safety assessment of edoxaban. Key efficacy and safety outcomes were adjudicated …

Die Diagnostik eines Myokardinfarktes ist mittels laborchemischer Analysen kardialer Marker, vor allem des hochsensitiven kardialen Troponins, mit hoher Spezifität und Sensitivität möglich und in Zusammenschau mit der entsprechenden Symptomatik und EKG-Veränderungen etabliert. Nach herzchirurgischen Eingriffen kann eine Troponinfreisetzung als Ausdruck einer prozeduralen Myokardschädigung auftreten. Ursachen hierfür sind beispielsweise Manipulation am Myokard oder die Verwendung von Kardioplegie bei Herzoperationen. Hierdurch ist die Diagnose eines perioperativen Myokardinfarktes jedoch herausfordernd, aber von höchster klinischer Relevanz. Studien zeigten, dass erhöhte Troponinwerte innerhalb der ersten 48 h postoperativ mit einer erhöhten Mortalität nach herzchirurgischem Eingriff korrelieren. Die B‑ACS-Pilotstudie untersuchte die Troponindynamik von 412 kardiochirurgischen …

Aims Current guidelines suggest calcium channel blockers (CCBs) as the second or third option for blood pressure management in patients with left ventricular assist device (LVAD). However, the clinical outcomes of patients with LVAD who receive CCBs remain unclear. Our study aims to analyse the association of CCBs with clinical outcomes in patients after LVAD implantation. Methods and results This is a retrospective analysis based on the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) from 2006 to 2017, and adult patients who were alive with LVAD and CCB treatment information at 6 months after implantation were included. Among 10 717 patients, 1369 received CCBs 6 months after implantation, and there was an increasing trend of CCB use after LVAD. Patients receiving CCB therapy at 6 months had a similar 5 year survival rate to those not receiving CCB [49.6%, 95 …

Aims Recurrent heart failure hospitalization (HFH) is an important feature of the progression of heart failure (HF). In the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial, we analysed risk factors for recurrent HFH events in HF patients with preserved ejection fraction (HFpEF) and developed a risk prediction model for recurrent HFH. Methods and results This analysis focused on the subset of TOPCAT participants enrolled in the Americas (n = 1767). Recurrent HFH was defined as two or more hospitalizations for HF during the follow‐up period. Lasso regression and multivariate logistic regression were used to screen the risk factors, and the risk prediction model of recurrent HFH was established. During a median follow‐up period of 3.4 (95% confidence interval: 3.3–3.6) years, 72.2% (542 of 751 total hospitalizations) of HFH events occurred in 9.4% (n = 163) of …

Aims Heart failure (HF) with preserved ejection fraction (HFpEF) is a disease associated with high morbidity and mortality, for which it is difficult to identify patients with the poorest prognosis in routine clinical practice. Carbohydrate antigen 125 (CA 125) has been shown to be a potential marker of congestion and prognosis in HF. We sought to better characterize HFpEF patients with high CA 125 levels by using a multimodal approach. Methods and results We prospectively enrolled 139 HFpEF patients (78 ± 8 years; 60% females) and 25 controls matched for age and sex (77 ± 5 years; 60% females). They underwent two‐dimensional echocardiography, cardiac magnetic resonance with late gadolinium enhancement [including extracellular volume (ECV) measurement], and serum measurements of CA 125 level. The primary endpoint of the study was a composite of all‐cause mortality or first HF hospitalization. The …

Aims Heart failure (HF) has shared genetic architecture with its risk factors: atrial fibrillation (AF), body mass index (BMI), coronary heart disease (CHD), systolic blood pressure (SBP), and type 2 diabetes (T2D). We aim to assess the association and risk prediction performance of risk‐factor polygenic risk scores (PRSs) for incident HF and its subtypes in bi‐racial populations. Methods and results Five PRSs were constructed for AF, BMI, CHD, SBP, and T2D in White participants of the Atherosclerosis Risk in Communities (ARIC) study. The associations between PRSs and incident HF and its subtypes were assessed using Cox models, and the risk prediction performance of PRSs was assessed using C statistics. Replication was performed in the ARIC study Black and Cardiovascular Health Study (CHS) White participants. In 8624 ARIC study Whites, 1922 (31% cumulative incidence) HF cases developed over 30 …

Aims Sodium‐glucose co‐transporter 2 (SGLT2) inhibitors have shown potential therapeutic benefits in heart failure (HF). However, data on their real‐world usage and benefits in acute decompensated heart failure (ADHF) are limited. Methods and results We conducted a post hoc analysis of real‐world data from 1108 patients with ADHF admitted to Nihon University Itabashi Hospital (Tokyo, Japan) between 2018 and 2022. Patients were divided into two groups based on the prescription of SGLT2 inhibitors during hospitalization: an SGLT2 inhibitor group (SGLT2i group) (n = 289) and a non‐SGLT2i group (n = 819). The primary endpoints were death and rehospitalization for HF after discharge. The median age was 76 [interquartile range (IQR): 66, 83] years, and 732 patients (66%) were male. Data showed an increasing trend in the prescription of SGLT2 inhibitors since 2021. During a median follow‐up period …

Aims MitraScore is a novel, simple, and manually calculatable risk score developed as a prognostic model for patients undergoing transcatheter edge‐to‐edge repair (TEER) for mitral regurgitation. As its components are considered prognostic in heart failure (HF), we aimed to investigate the usefulness of the MitraScore in HF patients. Methods and results We calculated MitraScore for 1100 elderly patients (>65 years old) hospitalized for HF in the prospective multicentre FRAGILE‐HF study and compared its prognostic ability with other simple risk scores. The primary endpoint was all‐cause deaths, and the secondary endpoints were the composite of all‐cause deaths and HF rehospitalization and cardiovascular deaths. Overall, the mean age of 1100 patients was 80 ± 8 years, and 58% were men. The mean MitraScore was 3.2 ± 1.4, with a median of 3 (interquartile range: 2–4). A total of 326 (29.6%), 571 (51.9 …

Aims Acute mitral regurgitation (MR) in the setting of myocardial infarction (MI) may be the result of papillary muscle rupture (PMR). This condition is associated with high morbidity and mortality. We aim to evaluate the feasibility of transcatheter edge‐to‐edge mitral valve repair (TEER) in this acute setting. Methods and results We analysed data from the International Registry of MitraClip in Acute Mitral Regurgitation following acute Myocardial Infarction (IREMMI) of 30 centres in Europe, North America, and the middle east. We included patients with post‐MI PMR treated with TEER as a salvage procedure, and we evaluated immediate and 30‐day outcomes. Twenty‐three patients were included in this analysis (9 patients suffered complete papillary muscle rupture, 9 partial and 5 chordal rupture). The patients' mean age was 68 ± 14 years. Patients were at high surgical risk with median EuroSCORE II 27% (IQR 16 …

Aims Frailty increases healthcare utilization and costs for patients with heart failure but is challenging to assess in clinical settings. Hand grip strength (GS) is a single‐item measure of frailty yet lacks evidence as a potential screening tool to identify patients at risk of higher unplanned events and related healthcare costs. We examined the association of baseline and longitudinal GS measurements with healthcare utilization and costs among patients with advanced heart failure. Methods and results Between July 2017 and April 2019, we enrolled 251 patients with symptoms of advanced heart failure (New York Heart Association class III or IV) in a prospective cohort study in Singapore. We measured GS at baseline and every 4 months for 2 years and linked patients' survey data with their medical and billing records. We categorized patients as having weak GS if their GS measurement was below the 5th percentile of the …

Aims The association between microRNAs (miRNAs) and established cardiac biomarkers is largely unknown. We aimed to measure the association between plasma miRNAs and N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP), cardiac troponin I, soluble urokinase‐type plasminogen activator receptor (suPAR), and galectin‐3 with cardiac structure and function and clinical outcomes. Methods and results We quantified 32 plasma miRNAs using the FirePlex miRNA assay and measured biomarkers in 139 individuals with symptomatic heart failure (HF). We used principal component (PC) analysis and linear regression to evaluate the association between miRNAs and biomarkers with ventricular size and function by echocardiography and Cox modelling for the incidence of a first composite event of HF hospitalization, heart transplant, left ventricular assist device implant, or death. The mean (standard …

Aims The multi‐systemic effects of heart failure (HF) resemble the spread observed during cancer. We propose a new score, named HLM, analogous to the TNM classification used in oncology, to assess the prognosis of HF. HLM refers to H: heart damage, L: lung involvement, and M: systemic multiorgan involvement. The aim was to compare the HLM score to the conventional New York Heart Association (NYHA) classification, American College of Cardiology/American Heart Association (ACC/AHA) stages, and left ventricular ejection fraction (LVEF), to assess the most accurate prognostic tool for HF patients. Methods and results We performed a multicentre, observational, prospective study of consecutive patients admitted for HF. Heart, lung, and other organ function parameters were collected. Each patient was classified according to the HLM score, NYHA classification, ACC/AHA stages, and LVEF assessed by …

Aims Achieving optimized guideline‐directed medical therapy (GDMT) is recommended prior to transcatheter mitral valve edge‐to‐edge repair (M‐TEER) for secondary mitral regurgitation (SMR). We aimed to propose and validate an easy‐to‐use score for assessing the quality of GDMT in patients with heart failure with reduced ejection fraction (HFrEF) undergoing M‐TEER. Methods and results Among the 1641 EuroSMR patients enrolled in the EuroSMR Registry who underwent M‐TEER, a total of 1072 patients [median age 74, interquartile range (IQR) 67–79 years, 29% female] had complete data on GDMT and a left ventricular ejection fraction ≤ 40% and were included in the current study.

Aims Among persons with prevalent heart failure (HF), iron deficiency has been linked to HF admissions, and intravenous iron replacement improves HF outcomes. Recent studies in persons with chronic kidney disease (CKD) demonstrate that iron deficiency is associated with incident HF. This study aimed to determine the relationship of iron status with incident HF in community‐dwelling older adults irrespective of their kidney function. Methods In this case‐cohort study, 1,006 Cardiovascular Health Study participants (785 from the random sub‐cohort [including 193 HF cases] and 221 additional HF cases [N = 414 total HF cases]) aged ≥ 65 years without HF (41% with CKD), we used weighted Cox models to evaluate associations of iron status with incident HF. Participants were categorized based on quartiles of transferrin saturation and ferritin as “iron replete” (27.3%), “functional iron deficiency” (7.7%), “iron …

Aims Red cell distribution width (RDW) is a strong prognostic marker in patients with heart failure (HF) and reduced ejection fraction and other conditions. However, very little is known about its prognostic significance in HF with preserved ejection fraction. We examined the relationship between RDW and outcomes and the effect of sacubitril/valsartan, compared with valsartan, on RDW and clinical outcomes in PARAGON‐HF. Methods and results PARAGON‐HF enrolled patients with a left ventricular ejection fraction of ≥45%, structural heart disease, and elevated N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP). The primary endpoint was a composite of total HF hospitalizations and cardiovascular deaths. Median RDW at randomization was 14.1% (interquartile range 13.5–15.0%). Patients with higher RDW levels were more often men and had more comorbidity, a higher heart rate and NT‐proBNP …

Aims Achieving optimized guideline‐directed medical therapy (GDMT) is recommended prior to transcatheter mitral valve edge‐to‐edge repair (M‐TEER) for secondary mitral regurgitation (SMR). We aimed to propose and validate an easy‐to‐use score for assessing the quality of GDMT in patients with heart failure with reduced ejection fraction (HFrEF) undergoing M‐TEER. Methods and results Among the 1641 EuroSMR patients enrolled in the EuroSMR Registry who underwent M‐TEER, a total of 1072 patients [median age 74, interquartile range (IQR) 67–79 years, 29% female] had complete data on GDMT and a left ventricular ejection fraction ≤ 40% and were included in the current study. We proposed a GDMT score that considers the dosage levels of three medication classes (angiotensin‐converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor‐neprilysin inhibitors, beta‐blockers …

Aims The early diagnosis of cardiac amyloidosis (CA) is paramount, since there are effective therapies that improve patient survival. The diagnostic accuracy of classical electrocardiographic (ECG) signs, such as low voltage, pseudoinfarct pattern, and conduction disturbances in the diagnosis of CA, is inferior to that of the echocardiographic myocardial deformation criteria; therefore, our aim was to find more accurate novel ECG criteria for this purpose. Methods We tested the diagnostic value of five novel ECG criteria, two of them devised by us, in 34 patients with confirmed CA (20 transthyretin amyloidosis and 14 AL amyloidosis) and 45 control patients with left ventricular hypertrophy on echocardiography due to hypertension, valvular aortic stenosis and hypertrophic cardiomyopathy. The following novel ECG criteria, that suggested CA, were tested: QRS amplitude in lead I < 0.55 mV (I < 0.55); QRS amplitude in …

Aims Current understanding of the prognosis for patients with chronic kidney disease (CKD) and overlapping cardio‐renal‐metabolic components, specifically heart failure (HF) and diabetes mellitus (DM), remains limited. While previous studies have explored the interactions between CKD, HF, and DM, they have predominantly focused on cohorts of HF or DM patients. This study aims to fill this gap by investigating the long‐term outcomes and treatment patterns in a cohort of CKD patients, particularly those with coexisting HF and DM. Methods and results We analysed data from the Swedish national CKD patient cohort, the Swedish Renal Registry, with a follow‐up period extending up to 10 years. The study examined the risks of all‐cause mortality, major adverse cardiovascular events (MACE)—defined as a composite of non‐fatal myocardial infarction, hospitalization for congestive HF, non‐fatal stroke, or …

Aims Peripartum cardiomyopathy (PPCM) is characterized by left ventricular (LV) dysfunction developing towards the end of pregnancy or in the first months postpartum. Although about 60% of women with PPCM (the majority of which are prescribed evidence based heart failure [HF] medications) show LV recovery within 6 to 12 months, others remain with persistently impaired LV function. Poor adherence to medical therapy represents a major cause of avoidable hospitalizations, disability, and death in other cardiovascular conditions. In this study, we aimed to determine drug adherence to HF therapy among women with PPCM and to identify possible associations between drug adherence and LV recovery, functional status and psychological well‐being. Methods and results In this single‐centre, prospective, observational study, we included 36 consecutive women with PPCM. Adherence to HF treatment was …

Management of patients with acute chest pain poses a significant challenge in identifying those requiring urgent coronary reperfusion. Electrocardiogram (ECG) constitutes the cornerstone in making prompt clinical decisions by identifying ST‐segment elevation, commonly associated with ST‐segment elevation myocardial infarction. It is important to note that ST‐segment elevation can also be a manifestation of various cardiac and non‐cardiac conditions, from acute myocarditis, early repolarization syndrome, acute pericarditis, and left bundle branch block to unknown origins. The similarity of ECG changes among these conditions complicates clinical differential diagnosis, necessitating a detailed medical history and thorough examinations. Here, we presented a case of a 52‐year‐old female with chest pain and unidentified convex ST‐segment elevation. Considering the negative emergent coronary angiography …
