Abstract
Glutamine is a critical amino acid that serves as an energy source, building block, and signaling molecule for the heart tissue and the immune system. However, the role of glutamine metabolism in regulating cardiac remodeling following myocardial infarction (MI) is unknown. In this study, we show in adult male mice that glutamine metabolism is altered both in the remote (contractile) area and in infiltrating macrophages in the infarct area after permanent left anterior descending artery occlusion. We found that metabolites related to glutamine metabolism were differentially altered in macrophages at days 1, 3, and 7 after MI using untargeted metabolomics. Glutamine metabolism in live cells was increased after MI relative to no MI controls. Gene expression in the remote area of the heart indicated a loss of glutamine metabolism. Glutamine administration improved left ventricle (LV) function at days 1, 3, and 7 after MI, which was associated with improved contractile and metabolic gene expression. Conversely, administration of BPTES, a pharmacological inhibitor of glutaminase-1, worsened LV function after MI. Neither glutamine nor BPTES administration impacted gene expression or bioenergetics of macrophages isolated from the infarct area. Our results indicate that glutamine metabolism plays a critical role in maintaining LV contractile function following MI and that glutamine administration improves LV function. Glutamine metabolism may also play a role in regulating macrophage function, but macrophages are not responsive to exogenous pharmacological manipulation of glutamine metabolism.NEW & NOTEWORTHY Glutamine metabolism is altered in both infarct macrophages and the remote left ventricle (LV) following myocardial infarction (MI). Supplemental glutamine improves LV function following MI while inhibiting glutamine metabolism with BPTES worsens LV function. Supplemental glutamine or BPTES does not impact macrophage immunometabolic phenotypes after MI.

Abstract
PURPOSE OF REVIEW This review examines the available evidence concerning the incidence of heart failure in patients with chronic coronary syndrome, with a focus on gender differences. RECENT FINDINGS The incidence of heart failure in the context of chronic coronary syndrome presents conflicting data. Most of the available information stems from studies involving stable patients' post-acute coronary syndrome, revealing a wide range of incidence rates, from less than 3% to over 20%, observed over 5 years of follow-up. Regarding the gender differences in heart failure incidence, there is no consensus about whether women exhibit a higher incidence, particularly in the presence of evidence of obstructive coronary artery disease. However, in cases where obstructive coronary artery disease is absent, women may face a more unfavourable prognosis due to a higher prevalence of microvascular disease and heart failure with preserved ventricular function. The different profile of ischaemic heart disease in women difficult to establish differences in prognosis independently associated with female sex. Targeted investigations are essential to discern the incidence of heart failure in chronic coronary syndrome and explore potential gender-specific associations.

Abstract
The presentation of acute coronary syndrome (ACS) in patients with type 2 diabetes mellitus (T2DM) may differ from that of non-diabetic patients, potentially leading to delayed diagnosis and treatment. This meta-analysis aimed to compare the clinical presentation of ACS between diabetic and non-diabetic patients. A systematic search of PubMed, Excerpta Medica database (EMBASE), and Web of Science databases was conducted for observational studies published from January 2010 onwards. Studies comparing ACS symptoms between diabetic and non-diabetic patients were included. The odds ratio (OR) with 95% confidence intervals (CI) was calculated using a random-effects model. Eight studies with a total of 29,503 patients (23.03% diabetic) were included. Diabetic patients were significantly less likely to present with chest pain compared to non-diabetic patients (OR: 0.43, 95% CI: 0.30 to 0.63, p<0.001). Anxiety (OR: 2.20, 95% CI: 1.17-4.14), shortness of breath (OR: 1.49, 95% CI: 1.11-2.01), and neck pain (OR: 1.62, 95% CI: 1.03-2.54) were significantly more common in diabetic patients. Sweating/cold sweat was less common in diabetics (OR: 0.60, 95% CI: 0.34-1.07), though not statistically significant. Other symptoms showed minimal differences between groups. High heterogeneity was observed across studies for most symptoms. This meta-analysis demonstrates that diabetic patients with ACS are less likely to experience typical chest pain and more likely to present with atypical symptoms such as anxiety, shortness of breath, and neck pain. These findings emphasize the need for healthcare providers to maintain high vigilance for atypical ACS presentations in diabetic patients. Tailored diagnostic approaches, modified triage protocols, and enhanced patient education are crucial to improving the timely diagnosis and treatment of ACS in this high-risk population.

Abstract
Background Exercise-based cardiac rehabilitation (CR) is a non-pharmacological multidisciplinary programme for individuals after myocardial infarction (MI) that offers multiple health benefits. One of the greatest barriers to CR participation is the travel distance to the rehabilitation centre. Remotely monitored CR appears to be at least as effective in improving cardiovascular risk factors and exercise capacity as traditional centre-based CR. Nevertheless, the efficacy of remotely monitored CR in individuals with a recent MI has yet to be examined. Methods A total of 30 individuals (8 women, 22 men) after a recent (i.e., <4 weeks) MI were randomly allocated into two groups (online home-based and gym-based groups). Both groups underwent a 26-week CR programme three times per week. All patients performed baseline and 24-week follow-up measurements where peak oxygen uptake (VO2peak), mean daily steps, distance, and calories were assessed. Results The online group showed an improvement in mean daily steps (p < 0.05) and mean daily distance (p < 0.05) at 24 weeks compared to the gym-based group. The paired-sample t-test showed that all the assessed variables were statistically (p < 0.001) improved for both groups at 24 weeks. Pearson's r demonstrated positive correlations between VO2peak and mean daily distance (r = 0.375), and negative correlations between VO2peak and muscle (r = -0.523) and fat masses (r = -0.460). There were no exercise-induced adverse events during the study. Conclusion Our findings might indicate that a real-time online supervised CR exercise programme using wearable technology to monitor the haemodynamic responses in post-MI patients is equally effective as a gym-based exercise programme.

Abstract
Purpose The aim of this study was to identify potential risk factors for myocardial infarction immediately following total hip arthroplasty. Methods The 2016-2019 Nationwide Inpatient Sample database was used to identify patients who underwent primary total hip arthroplasty (THA) and suffered a myocardial infarction (MI). Patient data including demographics, admission, and comorbidities were recorded. Univariate analysis and subsequent multivariate logistic regression were performed to determine which circumstances affected the odds of MI. Results A total of 367,890 patients were identified for THA with 142 of those also having a myocardial infarction. Those who experienced an MI had increased length of stay, total charges, and generally negative dispositions compared to their non-MI counterparts (p < 0.001). Through regression analysis, factors that increased the odds of MI included older age [odds ratio (OR) 1.59, 95 % confidence interval (CI) 1.49-1.70], a female sex (OR 1.46, 95 % CI 1.37-1.55), previous coronary artery bypass graft (OR 1.20, 95 % CI 1.01-1.43), obesity (OR 1.12, 95 % CI 1.04-1.21), colostomy (OR 2.07, 95 % CI 1.21-3.56), and Parkinson's disease (OR 1.48, 95 % CI 1.13-1.95). Factors that decreased that risk included elective admission (OR 0.21, 95 % CI 0.19-0.22) and a tobacco related disorder (OR 0.69, 95 % CI 0.63-0.76). Conclusions Patient risk for myocardial infarction following total hip arthroplasty varies in part based on their background and comorbidities. These findings can be used to better recognize those who should receive further precautions and tailor proper treatment strategies for THA.

Abstract
Acute coronary syndrome (ACS) can present with varied symptomatology, often deviating from classic presentations, particularly in patients without the characteristic chest pain. This case report describes an ST-elevation myocardial infarction (STEMI) that closely mimicked acute gastroenteritis, illustrating the challenges of differential diagnosis in atypical ACS presentations. We present the case of a 65-year-old Japanese male with a history of hypertension and dyslipidemia who arrived at the emergency department with acute abdominal pain, vomiting, diarrhea, and fever, symptoms suggesting viral gastroenteritis. The absence of chest pain diverted initial clinical suspicion away from cardiac causes. However, cardiovascular risk factors and a gallop rhythm prompted further cardiovascular evaluation. Subsequent blood tests and electrocardiogram findings suggested an acute myocardial infarction, later confirmed by coronary angiography as STEMI due to a 90% stenosis in the right coronary artery, which was successfully treated with percutaneous coronary intervention. The presentation of myocardial infarction can vary, with non-chest pain symptoms such as vomiting and fever occasionally leading the clinical picture, which may result in diagnostic delays and worsened prognosis. This case was particularly challenging due to the presence of all four symptoms typically associated with gastroenteritis, as well as the sequence of symptom onset being atypical for gastrointestinal diseases. This case exemplifies the need for a high degree of clinical suspicion for ACS in patients with atypical presentations, such as those mimicking gastroenteritis, to prevent misdiagnosis and ensure prompt and appropriate management, especially in patients with known cardiovascular risk factors.

Abstract
Introduction Sarcoidosis is a systemic inflammatory disorder characterised by non-caseating granulomas. Cardiac sarcoidosis (CS) normally causes conduction abnormalities, ventricular arrhythmias, and heart failure. Little is known about the characteristics and impact of sarcoidosis in patients admitted with ST-elevation myocardial infarction (STEMI). This study aims to fill this void. Material and methods Utilising the National Inpatient Sample (NIS) database (2016-2020), individuals with STEMI were identified and categorised based on sarcoidosis presence whilst adjusting for confounders via logistic regression models. Results Among 851,290 STEMI patients, 1215 had sarcoidosis. Before propensity matching, sarcoidosis patients were notably different in demographics and comorbidities compared to non-sarcoidosis patients. After propensity score matching (PSM), sarcoidosis patients were found to have a higher incidence of supraventricular tachycardia (SVT) (2.5% vs. 1.3%, p = 0.024) and acute kidney injury (AKI) (23.3% vs. 20.8%, aOR = 1.269, 95% CI: 1.02-1.58, p = 0.033) but a lower incidence of undergoing coronary artery bypass graft (CABG) (5.5% vs. 8.5%, aOR = 0.663; 95% CI: 0.472-0.931, p = 0.018), while no significant disparities were noted in PCI, cardiogenic shock, mortality, or mean length of stay (LOS). Conclusions Using propensity-matched large real-world data of STEMI patients, sarcoidosis was associated with fewer cases of CABG and a greater incidence of AKI and SVT compared to non-sarcoidosis patients.

Abstract
Background Epidemiological studies suggest sex differences in the prevalence and characteristics of unrecognized and recognized myocardial infarction (uMI, rMI). Despite increasingly diverse populations, observations are limited in multiethnic contexts. Gaining better understanding may inform policy makers and healthcare professionals on populations at risk of uMI who could benefit from preventive measures. Methods We used baseline data from the multiethnic population-based HELIUS cohort (2011-2015; Amsterdam, the Netherlands). Using logistic regressions, we studied sex differences in the prevalence and proportion of uMIs across ethnic groups. Next, we studied whether symptoms, clinical parameters, and sociocultural factors were associated with uMIs. Finally, we compared secondary preventive therapies in women and men with a uMI or rMI. We relied on pathological Q-waves on a resting electrocardiogram as the electrocardiographic signature for (past) MI. Results Overall, and in Turkish and Moroccan subgroups, the prevalence of uMIs was higher in men than women. The proportion of uMIs was similar in women (21.0%) and men (18.4%), yet varied by ethnicity. In women and men, symptoms (chest pain, dyspnea) and clinical parameters (hypertension, hypercholesterolemia), and in women also lower educational level and diabetes were associated with lower odds of uMIs. Women (0.0%) and men (3.6%) with uMI were unlikely to receive secondary preventive therapies compared to those with rMI (28.1-40.9%). Conclusions The prevalence of uMIs was higher in men than women, and sex differences in the proportion of uMIs varied somewhat across ethnic groups. People with uMIs did not receive adequate preventative medications, posing a risk for recurrent events.

Abstract
Objectives Childhood obesity is a growing health problem and requires a tailored treatment. This study explored the sex differences in cardiovascular risk factors in children/adolescents with obesity and in response to a weight loss intervention. Methods Five hundred and thirty-three children/adolescents with obesity and their parents underwent to a 3-months lifestyle intervention program. Tanner criteria were used to assess the pubertal stage. Before and after 3 months, anthropometric measurements, blood pressure (BP), and biochemical measurements were assessed. Results Four hundred and forty five participants completed the treatment (age 12.4 ± 2.7 years, males 45.8%, prepubertal 29.2%, BMI z score 2.3 ± 0.2). In comparison to boys, prepubertal girls had higher values of BMI z score (2.4 ± 02 vs. 2.3 ± 0.2, p < 0.05), waist circumference z score (2.2 ± 0.3 vs. 2.0 ± 0.3, p < 0.05), HOMA-IR [2.9 (2.1-4.9) vs. 2.3(1.5-3.6), p < 0.01], prevalence of hypertransaminasemia (41.3% vs. 17.7%, p < 0.05) and lower levels of HDL cholesterol (46.2 ± 9.8 vs. 51.2 ± 10.5 mg/dl, p < 0.05). In the pubertal stage, boys had worse cardiometabolic risk profile than girls, including unfavourable measure of systolic BP (z score: 0.6 ± 1.0 vs. 0.3 ± 1.0, p < 0.01), fasting glucose (87.2 ± 6.1 vs. 84.8 ± 7.7 mg/dl, p < 0.01), ALT (26.9 ± 21.5 vs. 20.2 ± 10.6 U/L, p < 0.001) and uric acid (6.1 ± 1.9 vs. 5.0 ± 1.0 mg/dl, p < 0.001). After the lifestyle intervention, changes in BMI z score (p < 0.05) were higher in pubertal boys than pubertal girls. The systolic blood pressure decrease was greater in pubertal boys than in their female counterpart (Δ systolic BP: -7.2 mmHg in boys vs. -3.6 mmHg in girls, p < 0.05; Δ systolic BP z score: -0.6 in boys vs. -0.3 in girls, p < 0.05). LDL cholesterol showed an improvement only in boys, and ALT in the whole group. Conclusion Our study showed that a short-term lifestyle intervention is more effective in reducing BMI z score and cardiovascular risk factors in pubertal boys than in their female counterparts. Further investigation is needed to deepen this gender difference, especially to develop a tailor-made intervention.

Abstract
Silent myocardial infarction (SMI) is a type of myocardial infarction (MI) that is asymptomatic or demonstrates mild symptoms; therefore, patients often do not seek medical treatment. SMI cases are often incidentally detected later by electrocardiogram (ECG). We present a case of a 59-year-old overweight woman with prediabetes, primary hypertension, and hypercholesterolemia who presented for herpes zoster (HZ) follow-up; she reported having skipped heartbeats and heart rate fluctuations during the review of systems. On further workup, ECG revealed low voltage QRS complexes, flat QRS complexes, flat T waves, and pathological Q waves, suggesting the diagnosis of SMI. Based on the identified risk factors, including high BMI, prediabetes, primary hypertension, hypercholesterolemia, HZ, and newly diagnosed SMI, the patient was advised to continue with lisinopril 20 mg daily, prescribed atorvastatin 80 mg daily, and was educated about maintaining a healthy diet, exercise, and receiving the shingles vaccination. To prevent the possible risks of poor outcomes such as those following MI, stroke, heart failure, arrhythmias, angina, and shortness of breath (SOB), the patient was referred to the cardiologist for a stress test and further treatment plan.
