Females at a Clear Disadvantage with Postoperative Myocardial Infarction Symptoms

Background: Cardiovascular disease remains the leading cause of death in women. Gender bias and blindness are coming into focus as relevant risk factors for patients. To date, there have been no studies that target surgeons’ potential gender bias in recognizing postoperative myocardial infarction (MI). Methods: An online clinical vignette describing a patient with postoperative MI was randomized for gender. Possible diagnoses, the next steps in management, and questions on gender bias were assessed. Results: A total of 205 surveys were analyzed. MI was recognized in 55.6% of the male case studies vs. 32.0% of the female case studies in the first question (p < 0.005). Cardiac diagnostics were initiated significantly more in male case studies (94% vs. 76%, p = 0.001). Female surgeons listed MI as the first diagnosis twice as often as male surgeons overall (43% vs. 23%, p = 0.027). Female surgeons were also more likely to mention MI across the survey at all compared to male surgeons (89% vs. 67%, p = 0.0002). Board-certified surgeons diagnosed MI by the end of the survey significantly more (88.2%) than residents (75.0%) and medical students (75.0%, p = 0.047). Conclusions: Overall, this study was able to demonstrate the presence of both gender bias and gender blindness in surgeons’ assessment of postoperative myocardial infarction symptoms with a clear disadvantage for female patients and a superior awareness for female surgeons.

The Role of Probiotics in Modulating Myocardial Infarction and Depression-like Symptoms: A Study on Sex-Specific Responses

Background/Objectives: This study explores the effects of two probiotics, Lactobacillus helveticus R0052 and Bifidobacterium longum R0175, on myocardial infarction (MI) and associated depression-like behaviours, with a focus on sex differences. Methods: MI was induced in adult male and female rats by occluding the left anterior coronary artery for 30 min, followed by 24 h of reperfusion. Probiotics were administered via drinking water for at least two weeks before ischemia. Infarct size, plasma C-reactive protein (CRP), estradiol levels, and intestinal permeability were then measured. Two weeks after, MI subgroups of rats were tested for depression-like behaviours. Results: We found a significant interaction between sex and probiotics in relation to infarct size. Probiotics significantly reduced the infarct size compared to the vehicle group in female rats but not in males. Probiotics increased the plasma estradiol levels and reduced the CRP concentrations in females, suggesting anti-inflammatory and cardioprotective properties. Probiotics significantly increased intestinal resistance following MI in males only, suggesting sex-specific physiological responses to treatment. Probiotics enhanced social interaction in males with MI but not in females. Similarly, in the forced swim test, probiotics reduced immobility in males with MI but increased it in females, further underscoring the sex-dependent effects of probiotics. Conclusions: This study reports cardioprotective effects of probiotics upon MI in female rats, while benefits in male rats were rather at the behavioural level. These results highlight distinct physiological and behavioural responses between sexes, emphasizing the need to account for sex differences in future tests of probiotics as a prophylactic treatment for MI.

Unveiling the Heart's Hidden Enemy: Dynamic Insights into Polystyrene Nanoplastic-Induced Cardiotoxicity Based on Cardiac Organoid-on-a-Chip.

Exposure to micro- and nanoplastics (MNPs) has been implicated in potential cardiotoxicity. However, in vitro models based on cardiomyocyte cell lines lack crucial cardiac characteristics, while interspecies differences in animal models compromise the reliability of the conclusions. In addition, current research has predominantly focused on single-time point exposures to MNPs, neglecting comparative analyses of cardiac injury across early and late stages. Moreover, there remains a large gap in understanding the susceptibility to MNPs under pathological conditions. To address these limitations, this study integrated cardiac organoids (COs) and organ-on-a-chip (OoC) technology to develop the cardiac organoid-on-a-chip (COoC), which was validated for cardiotoxicity evaluation through multiple dimensions. Based on COoC, we conducted a dynamic observation of the cardiac damage caused by short- and long-term exposure to polystyrene nanoplastics (PS-NPs). Oxidative stress, inflammation, disruption of calcium ion homeostasis, and mitochondrial dysfunction were confirmed as the potential mechanisms of PS-NP-induced cardiotoxicity and the crucial events in the early stages, while cardiac fibrosis emerged as a prominent feature in late stages. Notably, low-dose exposure exacerbated myocardial infarction symptoms under pathological states, despite no significant cardiotoxicity shown in healthy models. In conclusion, these findings further deepened our understanding of PS-NP-induced cardiotoxic effects and introduced a promising in vitro platform for assessing cardiotoxicity.

Low income, being without employment, and living alone: How they are associated with cognitive functioning - Results from the German National Cohort (NAKO)

Abstract Background While people with low socioeconomic status tend to have worse cognitive functioning, little is known about the impact of specific socioeconomic conditions. Aim of the present analysis was to investigate to what extent cognitive functioning differs by three socioeconomic conditions: low income, being without employment, and living alone. Methods A total of N = 158,144 participants (age 19-75 years) of the population-based German National Cohort (NAKO) provided data on socioeconomic conditions and completed cognitive testing. Multivariable regression model including the three socioeconomic conditions, age, sex, education, occupational status, having diabetes, hypertension, myocardial infarction, stroke, and depressive symptoms was used for analysis. Results Results from fully adjusted analysis indicated that cognitive functioning (z-score) was lower among those with low income (b=-0.53, CI95%=-0.57; -0.49) compared to not having low income, living alone (b=-0.10, CI95%=-0.14; -0.07) compared to not living alone, and being without employment (b=-0.22, CI95%=-0.27; -0.17) compared to being employed. The difference in cognitive functioning between those exposed compared to not exposed to the condition was changing slightly with older age among those with low income (interaction with age b=-2.39, CI95%=-3.24; -1.55) and, to a smaller extent, among those living alone (interaction with age b=-0.76, CI95%=-1.34; -0.19). Conclusions Low income, being without employment, and living alone were independently associated with poorer cognitive functioning after adjusting for confounders. As those with low income had the poorest cognitive functioning in old age, it is important to explore pathways of how cognitive health in this population group can be improved.

Cardiac Syndrome X - A mystery to worry about.

Madam, Cardiac syndrome X, by definition means original pain without any evidence of significant CVD visualized on angiogram. Normal angiogram makes it difficult for medical practitioners to detect this syndrome. About 10-20% of persons who undergo coronarography suffers from cardiac syndrome X [1]. It has the highest prevalence in postmenopausal women [2]. Most common indication is symptoms of myocardial infarction in patients [3]. Recent study by Magdalena Piegza et al shows the cardiac syndrome patients suffer from anxiety disorders, depressive symptoms and sleep disturbances [4]. This syndrome brings a great concern to Pakistan as already we have a high rate of anxiety disorders, heart problems and higher ratio of deaths due to CVD. A study conducted on 423 persons in tertiary care hospital in Karachi showed the mean anxiety value to be 28.3% [5]. A complete diagnosis of the syndrome requires proper checkup and follow up, but inadequate procedural managements culminating due to lack of interest and awareness raise a high risk of cardiac syndrome X in Pakistan. A thorough online literary search on the PubMed did not find a single article about this issue pointing to the lack of interest and awareness among the medical practitioners of Pakistan. It has to be made sure by creating awareness driven by seminars and workshops to apprise doctors about this syndrome. A study by the Institute for Health Metrics and Evaluation found that 38% of deaths in Pakistan are due to ischemic heart diseases [6]. This increases the chances of cardiac syndrome X among the local population. Due diligence in medical care and follow up must be applied to patients reaching out with past history of anxietic disorders and ischemic heart problems. Common public awareness is also important and doctors should emphasize on ensuring proper lifestyle including diet, exercise, smoking cessation and weight reduction.

Diagnostic accuracy of signs and symptoms in acute coronary syndrome and acute myocardial infarction

Background Acute coronary syndrome (ACS) and acute myocardial infarction (AMI) account for a large portion of cardiovascular deaths. Signs and symptoms for these syndromes, such as chest pain, are non-specific and can be caused by a variety of non-cardiac conditions, especially in low-prevalence settings such as general practice. The diagnostic value of these signs and symptoms can be assessed using diagnostic meta-analyses, but the last one dates from 2012. Methods We performed a diagnostic meta-analysis in accordance with PRISMA guidelines. We searched PubMed, Embase and CENTRAL from 2006 to 2024. We included studies that assessed the diagnostic accuracy of thirteen different signs and symptoms. We divided patients into two subgroups (AMI and ACS) on which analysis was performed independently. Results We selected 24 articles for inclusion. Our analysis indicates that signs and symptoms have a limited role in the diagnosis of AMI or ACS. The most useful (highest diagnostic odds ratios, DOR) in the diagnosis of AMI were pain radiating to both arms (DOR 2.95 (95%CI 1.57–5.06)), absence of chest wall tenderness (DOR 3.51 (95%CI 1.64–6.61)), pain radiating to the right arm (DOR 5.17 (95%CI 1.77–11.9)) and sweating (DOR 5.75 (95%CI 2.51–11.4)). For ACS these were pain radiating to the right arm (DOR 3.9 (95%CI 0.7–12.6)) and absence of chest wall tenderness (DOR 7.73 (95%CI 2.19–19.8)). Conclusion We report the accuracy of thirteen signs and symptoms in the diagnosis of AMI and ACS. These can be useful to calibrate general practitioners’ diagnostic assessment of chest pain in primary care settings.

7531 Spontaneous Coronary Artery Dissection Induced Diabetic Ketoacidosis In A Young Female: A Rare Complication Of Ketosis In A Priorly Non-Insulin Dependent Diabetic

Abstract Disclosure: F. farhat: None. P. Gonzalez: None. A.B. Ravin: None. H. Akhlaq: None. M. hossain: None. K. chalasani: None. S.W. Holland: None. R. Ong: None. J. Cheng: None. Introduction: Spontaneous Coronary Artery Dissection (SCAD) is a poorly understood and underdiagnosed condition that puts healthy young women at risk of Myocardial infarction (MI) and potential death. It occurs when a tear develops in a coronary artery. SCAD can have an atypical presentation especially in diabetic and young females; Diabetic ketoacidosis (DKA) is an uncommon, yet potentially fatal complication and can be the primary presentation in SCAD. We present a case of SCAD complicated by DKA in a non insulin dependent diabetic (NIDD).Case presentation: A 19 year old female with a past medical history of NIDDM presented to the Emergency Department with chest pain. She had troponemia and ECG revealed ST elevations. Patient was found in DKA initially. Insulin drip was started with DKA resolution in 24 hours. Hemoglobin A1c was 12.4% with negative antibody workup. Her course was complicated by SCAD found upon cardiac catheterization with unsuccessful recanalization; she was not a surgical candidate given late presentation and therefore, an intra aortic balloon pump was placed. Subsequently, she developed pericarditis and left ventricular thrombus. Discussion: SCAD is a rare condition, often presenting with acute MI and cardiogenic shock. MI may be complicated with DKA. One proposed mechanism for that is the activation of ketogenic pathways caused by excess catecholamines and cortisol; this increases physiologic stress on the body resulting in increased ketogenesis, lipolysis and free radicals causing further myocardial injury. DKA precipitated by MI increases the mortality rate to nearly 85% since the myocardium is denied glucose uptake. Signs and symptoms of SCAD are similar to MI symptoms including: chest tightness, shortness of breath and sweating. MI and SCAD can be differentiated by cardiac catheterization or by specialized contrasted CT scans. 20% of SCAD patients will experience a second episode within 5 years. Avoiding emotional stress, exercising regularly, following a healthy diet and controlling chronic conditions can help lower the risk for SCAD. Medical management is often preferred. Invasive treatments like coronary stenting or cardiac bypass may be needed if there is a complete blockage in the vessel, clinical instability or ongoing chest pain. Conclusion: SCAD is an important cause of MI in young females and can present initially as DKA in diabetics. For clinicians facing such rare cases, it is worth maintaining a broad approach to the diagnosis and treatment of these patients. The causes of SCAD remain fully unclear and genetic relations are still under investigation. Since DM type I and SCAD occur in young people, it is extremely important for clinicians to consider SCAD in the differential while managing DKA. Presentation: 6/3/2024

Prevalence of peripheral artery disease in young coronary artery disease patients

Background and objectives. Peripheral artery disease (PAD) and coronary artery disease (CAD) are progressive inflammatory conditions caused by arteriosclerosis, typically presenting after the age of 50. However, assessing peripheral vascular disease (PVD) in younger populations may offer early indications of coronary heart disease (CHD) risk. This study investigates the prevalence of abnormal ankle brachial index (ABI) values among young myocardial infarction (MI) patients and examines the correlation of ABI with other cardiovascular risk factors. Material and methods. This cross-sectional study was conducted at Saveetha Medical College and Hospital, involving 147 patients aged 40 years or younger who were admitted with MI symptoms. The study focused on the incidence and severity of MI in relation to age, sex, and the presence of risk factors such as smoking, alcohol use, dyslipidemia, hypertension (HTN), and diabetes mellitus (DM). Results. The study analyzed the incidence of myocardial infarction (MI) in a population under 40 years old. It was found that the incidence rate increased with age within this group. Specifically, males were more frequently affected than females, with 70% of cases occurring in males. Among female participants, all were over 30 years old. In terms of ankle-brachial index (ABI) values, 40% of females exhibited abnormal ABI, compared to 25% of males. Significant risk factors identified included smoking, with 60% of participants reporting tobacco use, alcohol consumption at 50%, and dyslipidemia present in 45% of cases. Hypertension (HTN) and diabetes mellitus (DM) were less prevalent, affecting 20% and 15% of participants, respectively. There was a significant correlation between low ABI values and the use of tobacco (p<0.01) and alcohol (p<0.05). However, the analysis showed no significant relationship between the number of vascular involvements indicated by ABI and the length of hospital stay. The length of hospital stay did increase with patient age, with an average increase of 2 days for every decade of age, but this was not significantly associated with ABI values. Conclusion. ABI is a valuable diagnostic tool in young populations for detecting early signs of CHD, offering advantages over routine blood pressure measurements. This study supports the broader use of ABI in both young and older populations to improve early detection and management of cardiovascular risks. Further research is needed to explore the implications of ABI in routine clinical practice and its correlation with other cardiovascular risk factors.

The Aortic Prosthesis and Aortic Valve Bioprosthesis Trombosis as a Late Complication in Patients after the Bentall Procedure Followed by a Valve-in-Valve Transcatheter Aortic Valve Implantation.

Background: Valve-in-Valve (ViV) transcatheter aortic valve implantation (TAVI) has emerged as a viable therapeutic option for structural valve degeneration following surgical aortic valve replacement (SAVR) or prior TAVI. However, the understanding of long-term complications and their management remains limited. Case presentation: We present the case of a 69-year-old male with a history of ViV-TAVI, who presented with symptoms of non-ST elevation myocardial infarction (NSTEMI) and transient ischemic attack (TIA). Computed tomography (CT) revealed thrombosis of the ascending aortic graft and aortic valve prosthesis. Transthoracic echocardiography (TTE) further confirmed new valve dysfunction, indicated by an increase in the aortic valve mean gradient. Treatment with low-molecular-weight heparin (LMWH) resulted in partial thrombus resolution. The multidisciplinary Heart Team opted against coronary angiography and recommended the long-term administration of vitamin K antagonists (VKAs). Follow-up CT showed the complete resolution of the thrombus. Conclusions: Thrombosis of the aortic graft and aortic valve following ViV-TAVI may be attributed to alterations in blood flow or mechanical manipulations during the TAVI procedure, yet it can be effectively managed with VKA therapy. CT is a valuable tool in coronary assessment in patients with NSTEMI and aortic valve and/or aortic graft thrombosis.

A Routine Coronary Angiography before Carotid Endarterectomy as an Example of Interdisciplinary Work: The Immediate Results of the Surgery.

The aim: to evaluate the incidence of obstructive lesions of the coronary arteries during routine coronary angiography (CAG) before carotid endarterectomy (CEA) and the incidence of perioperative complications. Materials and Methods: We examined a continuous sample of 498 patients before CEA who underwent an invasive evaluation of the coronary bed during CAG. Depending on the hemodynamic significance of coronary artery lesions, the patients were divided into three groups: group I-obstructive coronary artery disease (≥70%) (n = 309, 62.0%); group II-non-obstructive lesions of the coronary arteries (<70%) (n = 118, 23.7%); group III-intact coronary arteries (n = 71, 14.3%). The groups were compared with each other according to the data of the preoperative examination (clinical and anamnestic parameters, laboratory data and results of echocardiography), as well as according to the immediate results of the operation. In the hospital period, adverse cardiovascular events were assessed: death, myocardial infarction (MI), stroke, arrhythmias, atrial fibrillation or flutter (AF/AFL) and combined endpoint. Results: The groups differed significantly in the presence of symptoms of angina pectoris, myocardial infarction and myocardial revascularization procedures in their medical history and in the presence of chronic ischemia of the lower extremities. However, in the group of intact coronary arteries, the symptoms of angina were in 14.1% of patients, and a history of myocardial infarction was in 12.7%. Myocardial revascularization before CEA or simultaneously with it was performed in 43.0% of patients. As a result, it was possible to reduce the number of perioperative cardiac complications (mortality 0.7%, perioperative myocardial infarction 1.96%). Conclusions: The high incidence of obstructive lesions in the coronary arteries in our patients and the minimum number of perioperative complications favor routine CAG before CEA.

Routine Coronary Angiography and Functional Cardiac Tests before Resection of Abdominal Aortic Aneurysm in Patients without Symptoms of Myocardial Infarction

INTRODUCTION: Cardiac complications are leaders in the structure of mortality of patients after resection of abdominal aortic aneurysms (AAA). In recent years more data have been obtained on the possibility of performing invasive coronary angiography (CAG) as a method of preoperative assessment of the condition of the coronary arteries. AIM: To assess the tactics of routine CAG and preventive revascularization of the myocardium in comparison with non-invasive functional tests in patients without clinical manifestations of coronary heart disease (CHD) from positions of the hospital outcomes of AAA resections. MATERIALS AND METHODS: A retrospective study included 205 patients without clinical and instrumental signs of CHD who underwent AAA resection at National Medical Research Center of Surgery named after A. Vishnevsky in 2001–2021. Patients of the first group (n = 55) underwent CAG before AAA resection and, if significant stenosis of coronary arteries was detected, revascularization of the myocardium was performed. In patients of the second group (n = 71), only functional cardiac tests were conducted before the operation. Patients of the third group were operated on without additional evaluation of cardiac status. RESULTS: In 30.9% of patients of the first group, significant coronary lesions were detected, in 29.5% of them with the involvement of the left main coronary artery. This required 10 percutaneous coronary interventions and 5 coronary artery bypass surgeries, which made 27.0% of patients in this group. No cases of myocardial infarction were recorded in this group. In the second and third groups, one case of myocardial infarction in each group was recorded (p = 0.688). There was no significant difference in the postoperative mortality in all the groups (1.8%; 4.2%; 2.5%, respectively; p = 0.704). To this end, maximally invasive diagnostic tactics increased the average waiting time for AAA resection: 52.2 ± 6.0 days in groups without coronary angiography and myocardial revascularization versus 99.2 ± 13.0 days in the first group. CONCLUSION: In a cohort of patients without anamnestic and clinical manifestations of coronary artery disease, the tactics of routine coronary angiography followed by prophylactic myocardial revascularization did not improve the short-term results of AAA resection, while the waiting period for intervention on the abdominal aorta increased. Preoperative tactics with functional cardiac tests also did not affect the treatment results.

Women Acute Myocardial Infarction-Identifying and Understanding the Gender Gap (WAMy-GAP): A Study Protocol.

Barriers to accessing care and misinterpretations of ischemic heart disease symptoms due to lack of awareness contribute to women's delay in seeking care. Women may delay seeking treatment for up to 3 h or even up to 5 days. They often perceive themselves to be at low risk of cardiovascular disease (CVD) and prioritize family responsibilities or household chores. The causes of this delay are multifactorial and influence the decision-making process, particularly in the pre-hospital phase. The objective of this study protocol is to evaluate prodromal symptoms and identify risk behaviors in women with acute myocardial infarction (AMI). This is a protocol for a multicenter study that will be conducted using the mixed-method methodology using the McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey (MAPMISS) to evaluate symptoms and semi-structured interviews to investigate behaviors. This study protocol is intended to fill an important knowledge gap on premonitory and acute symptoms of AMI in women in Italy, as well as to understand the causes and mechanisms underlying delays in accessing healthcare services during an acute event such as AMI. The investigation of this issue will facilitate the removal of gender-related inequalities in the diagnosis and treatment of acute myocardial infarction while also fostering dialogue on the barriers to behavior change.

Clinical, Anamnestic, and Demographic Characteristics of Patients with Myocardial Infarction in Russian Federation According to the Russian Registry of Acute Myocardial Infarction - REGION-IM.

Based on data from the Russian REGION-MI registry, to characterize patients with myocardial infarction (MI) hospitalized in Russian hospitals, describe their historical, demographic, and clinical characteristics, and compare the results with the data of previous Russian and international registries of acute coronary syndrome. REGION-MI is a multicenter prospective observational study. The follow-up period was divided into three stages: during the hospital stay, at 6 and 12 months after the inclusion in the registry. Demographic and historic data and information about the present case of MI were entered into the patient's individual record card. The median age of all patients was 63 years; 68% of patients were men. The mean age of women was older than that of men. Among all MI cases, 70% were ST-segment elevation myocardial infarction (STEMI). Patients with non-ST-segment elevation myocardial infarction (NSTEMI) were older and had more comorbidities than patients with STEMI. The median time from the first symptoms to ECG recording was two hours, and from the first symptoms to CAG 7 hours. CAG was performed in 91% of patients with STEMI and 84% of patients with NSTEMI. Stenting was performed in 69% of patients. Although many patients had a complicated cardiovascular history, at the time of admission only 31.5% of patients were taking at least one drug from the groups of antiplatelets, oral anticoagulants, statins, and beta-blockers. Patients with MI in the Russian Federation are younger than patients with MI in European countries. Among the clinical and historical characteristics, conspicuous is the presence of modifiable risk factors in many patients, as well as the presence of a previous diagnosis of ischemic heart disease. Furthermore, a small proportion of patients took statins, antiplatelet agents or anticoagulants at the outpatient stage, which indicates a great reserve of both primary and secondary prevention of cardiovascular diseases in the Russian Federation. The delayed seeking medical help is also noticeable, which indicates the need for increasing the public awareness of the symptoms of MI and the importance of timely hospitalization.

A randomized clinical trial of catheter ablation and antiarrhythmic drug therapy for suppression of ventricular tachycardia in ischemic cardiomyopathy: The VANISH2 trial

Recurrent ventricular tachycardia (VT) in patients with prior myocardial infarction is associated with adverse quality of life and clinical outcomes, despite the presence of implanted defibrillators (ICDs). Suppression of recurrent VT can be accomplished with antiarrhythmic drug therapy or catheter ablation. The Ventricular Tachycardia Antiarrhythmics or Ablation In Structural Heart Disease 2 (VANISH2) trial is designed to determine whether ablation is superior to antiarrhythmic drug therapy as first line therapy for patients with ischemic cardiomyopathy and VT.The VANISH2 trial enrolls patients with prior myocardial infarction and VT (with one of: ≥1 ICD shock; ≥3 episodes treated with antitachycardia pacing (ATP) and symptoms; ≥5 episodes treated with ATP regardless of symptoms; ≥3 episodes within 24 hours; or sustained VT treated with electrical cardioversion or pharmacologic conversion). Enrolled patients are classified as either sotalol-eligible, or amiodarone-eligible, and then are randomized to either catheter ablation or to that antiarrhythmic drug therapy, with randomization stratified by drug-eligibility group. Drug therapy, catheter ablation procedures and ICD programming are standardized.All patients will be followed until two years after randomization. The primary endpoint is a composite of mortality at any time, appropriate ICD shock after 14 days, VT storm after 14 days, and treated sustained VT below detection of the ICD after 14 days. The outcomes will be analyzed according to the intention-to-treat principle using survival analysis techniques.The results of the VANISH2 trial are intended to provide data to support clinical decisions on how to suppress VT for patients with prior myocardial infarction.Clinicaltrials.gov registration NCT02830360

Age and healthy lifestyle behavior’s disparities and similarities on knowledge of myocardial infarction symptoms and risk factors among public and outpatients in a resource-limited setting, cross-sectional study in greater Gaborone, Botswana

Objectives In this cross-sectional study from Botswana, we investigated knowledge of myocardial infarction (MI) symptoms and risk factors among the general public and outpatients with MI risk factors based on age and lifestyle behaviors, in addition to assessing associations with sociodemographic and MI risk factors.Method Open-ended questionnaires about 8 MI symptoms and 10 risk factors, were administered by research assistants to a representative selection of outpatients (n = 525) and the public (n = 2248). Weight and height were measured in all participants and BMI was calculated. Knowledge scores were compared between the two groups. We examined whether sociodemographic and MI risk factors had impact on the scores. Analyses were further adjusted for lifestyle behavior (smoking status, dietary status and physical activities).ResultsThe valid response rate was 97.9% comprising 97.8% for the public (n = 2199) and 98.1% for outpatients (n = 515). Public respondents (35.2 ± 12.3 years) were younger than outpatients (38.5 ± 12.6 years). The public comprised 56.9% females while outpatients 54.6%.In general, outpatients had higher knowledge of MI symptoms than the public, with mean scores ± SD of 3.49 ± 2.84 vs 2.80 ± 2.54. Outpatients also had higher knowledge score of MI risk factors than the public, with mean scores, 5.33 ± 3.22 vs 3.82 ± 3.07. For MI symptoms, outpatients were more aware than the public for chest pains among all ages, for arm pain/ numbness, neck/ jaw pain radiating to/ from chest, and feeling sick or looking pallor on the skin among those aged 35–49 years.Among both the public and outpatients, lower knowledge of both MI symptoms and risk factors was associated with primary education, not residing/working together, history of hypertension, no history of heart disease/stroke, and obesity. There were similarities and disparities on MI knowledge among respondents with various numbers of healthy lifestyle behaviours.ConclusionResults call for urgent educational campaigns on awareness and knowledge of MI and using strategies based on age and lifestyle behavior.

Public Awareness of Early Symptoms of Acute Myocardial Infarction in Arar, Saudi Arabia

Background: A significant factor in patient delays is a lack of understanding of MI symptoms. Denial, fear, and an undue reliance on self-management could be the causes of more delays. This study aimed to assess the level of public awareness concerning the early symptoms of acute myocardial infarction (MI) and the appropriate actions to be taken when these symptoms manifest in the population of Arar, Saudi Arabia. Methods: A cross-sectional design employing a quantitative approach was used. Data were collected through an online self-administered questionnaire distributed to 390 participants using convenience sampling. The collected data were analyzed using descriptive and inferential statistics. Results: The study revealed mixed awareness levels among participants. While 63.6% correctly recognized chest pain as a symptom of MI, only 61.8% identified radiating pain to the shoulder, arm, back, neck, and jaw as an alarming symptom. Additionally, 74.9% recognized shortness of breath, and 64.6% identified fatigue as potential MI symptoms. Other symptoms, such as cold sweats (57.2%) and nausea (40.3%), were less well-known. Among the recognized risk factors, smoking (86.7%), diabetes (64.1%), and hypertension (79%) were relatively well-acknowledged, while obesity (84.4%) and sedentary lifestyles (86.9%) were recognized to a lesser extent. Age, education, income, city of residence, personal or family history of MI, history of MI among acquaintances, and exposure to AMI information in media and books significantly influenced awareness scores (p &amp;lt; 0.05). Conclusion: The study underscores the importance of tailored public health interventions to enhance MI awareness, especially among younger individuals, those with higher education, and those with lower incomes. It highlights the need for addressing lesser-known risk factors, such as obesity and sedentary lifestyles, to comprehensively prevent MI.

Association Between Acute Myocardial Infarction Symptoms and Short- and Long-term Mortality After the Event

BackgroundIn this study, we investigated various acute myocardial infarction (AMI) symptoms and their associations with short-term (28 day) and long-term mortality. MethodsThe analysis was based on 5900 patients, aged 25 to 84 years, with first-time AMI recorded by the population-based Myocardial Infarction Registry Augsburg between 2010 and 2017. Median follow-up time was 3.8 years (interquartile range: 1.1-6.3). As part of a face-to-face interview, the presence (yes/no) of 11 most common AMI symptoms at the acute event was assessed. Using multivariable-adjusted logistic regression and Cox regression models, the association between various symptoms and all-cause mortality was investigated. P values of the regression models were false discovery rate adjusted. ResultsPain in various body parts (chest pain, left and right shoulder/arm/hand, between shoulder blades), sweating, nausea/vomiting, dizziness and fear of death/feeling of annihilation were significantly associated with a decreased 28-day mortality after AMI. The pain symptoms and sweating were also significantly associated with a decreased long-term mortality. Shortness of breath was significantly associated with a higher long-term mortality. ConclusionsThe absence of several symptoms, including typical chest discomfort (chest pain or retrosternal pressure/tightness), is associated with unfavourable outcomes after AMI. This finding has implications for patient management and public health measures designed to encourage appropriate and prompt medical consultation of patients with atypical AMI symptoms.

Exploring Myocardial Infarction Knowledge, Attitudes, and Practice Among Mogadishu's Somali Residents.

Myocardial infarction and cardiovascular disease are significant global health issues, particularly in Somalia. The Somali population faces challenges due to armed conflict, limited education, and underdeveloped healthcare infrastructure. Cardiovascular risk factors like diabetes, hypertension, and obesity are prevalent, and Somali people face increased susceptibility. This study examined Somalia residents' perceptions, attitudes, and behaviors towards myocardial infarction using a cross-sectional paper-based questionnaire. The sample consisted of 313 urban residents in Mogadishu, aged 20 and above. The questionnaire was written in Somali and was designed for the demographic. Knowledge, attitude, and practice scores were categorized into two groups, with associations between knowledge, attitude, and practice with sociodemographic and health characteristics assessed using Logistic Regression. This study analyzed data from A random sample of participants who arrived at the hospital for various reasons regarding their perceptions, attitudes, and responses towards myocardial infarction. The mean age was 42 ±19 years, with 54% being male and 46% female. Hypertension was the most common comorbidity, followed by dyslipidemia and diabetes. Over half of the respondents had no formal education, and only 3.8% had a smoking history. About 5.7% had a previous history of myocardial infarction. The mean knowledge score was 11.07 ± 0.697, with 53.35% of respondents not knowing enough about myocardial infarction. The majority of the patients showed a favorable attitude, but only a slight majority could recognize symptoms of myocardial infarction. The majority of the patients had inadequate practice and behavior, with 53.6% not practicing regularly or engaging in sports. The research highlights gaps in Mogadishu's Somali community's knowledge and practices regarding myocardial infarction. It emphasizes the need for health education, primary care, and community involvement to improve cardiovascular health awareness and reduce MI incidence.

Insulin resistance in Takotsubo syndrome.

Takotsubo syndrome (TTS) is an acute heart failure (AHF) syndrome mimicking the symptoms of acute myocardial infarction. Impaired outcome has been shown, making risk stratification and novel therapeutic concepts a necessity. We hypothesized insulin resistance with elevated plasma glucose and potentially myocardial glucose deprivation to contribute to the pathogenesis of TTS and investigated the therapeutic benefit of insulin in vivo. First, we retrospectively analysed patient data of n=265 TTS cases (85.7% female, mean age 71.1±14.1years) with documented initial plasma glucose from the Department of Cardiology of the University Hospital Heidelberg in Germany (May 2011 to May 2021). Median split of the study population according to glucose levels (≤123mg/dL vs. >123mg/dL) yielded significantly elevated mean heart rate (80.75±18.96 vs. 90.01±22.19b.p.m., P<0.001), left ventricular end-diastolic pressure (LVEDP, 18.51±8.35 vs. 23.09±7.97mmHg, P<0.001), C-reactive protein (26.14±43.30 vs. 46.4±68.6mg/L, P=0.006), leukocyte count (10.12±4.29 vs. 15.05±9.83/nL, P<0.001), peak high-sensitive Troponin T (hs-TnT, 515.44±672.15 vs. 711.40±736.37pg/mL, P=0.005), reduced left ventricular ejection fraction (EF, 34.92±8.94 vs. 31.35±8.06%, P<0.001), and elevated intrahospital mortality (2.3% vs. 12.1%, P=0.002) in the high-glucose group (Student's t-test, Mann-Whitney U test, or chi-squared test). Linear regression indicated a significant association of glucose with HR (P<0.001), LVEDP (P=0.014), hs-TnT kinetics from admission to the next day (P<0.001), hs-TnT the day after admission (P<0.001), as well as peak hsTnT (P<0.001). Logistic regression revealed significant association of glucose with a composite intrahospital outcome including catecholamine use, respiratory support, and resuscitation [OR 1.010 (1.004-1.015), P=0.001]. To further investigate the potential role of glucose in TTS pathophysiology experimentally, we utilized an in vivo murine model of epinephrine (EPI)-driven reversible AHF. For this, male mice underwent therapeutic injection of insulin (INS, 1IU/kg) or/and glucose (GLU, 0.5g/kg) after EPI (2.5mg/kg), both of which markedly improved mean EF (EPI 34.3% vs. EPI+INS+GLU 43.7%, P=0.025) and significantly blunted mean hs-TnT (EPI 14393pg/mL vs. EPI+INS 6864pg/mL at 24h, P=0.039). Particularly, insulin additionally ameliorated myocardial pro-inflammatory gene expression, suggesting an anti-inflammatory effect of acute insulin therapy. Elevated initial plasma glucose was associated with adverse outcome-relevant parameters in TTS and may present a surrogate parameter of heightened catecholaminergic drive. In mice, insulin- and glucose injection both improved EPI-induced AHF and myocardial damage, indicating insulin resistance rather than detrimental effects of hyperglycaemia itself as the underlying cause. Future studies will investigate the role of HbA1c as a risk stratifier and of insulin-based therapy in TTS.

Awareness of Myocardial Infarction Symptoms and Risk Factors in Saudi Arabia: A Cross-Sectional Study.

Background Cardiovascular disease is the leading global cause of mortality. Recognition of myocardial infarction (MI) symptoms is crucial as it influences clinical outcomes. Furthermore, awareness of MI risk factors assists in obtaining healthier lifestyles, alleviating its burden and mortality rates. This study aims to evaluate the awareness levels of the general population in Saudi Arabia regarding MI symptoms and risk factors and to identify its determinants. Methods A descriptive cross-sectional study was conducted among the general Saudi population, with 1,247 participants, excluding those residing outside Saudi Arabia and healthcare-related individuals. An online self-administered questionnaire encompassed sociodemographic characteristics, awareness of MI symptoms and risk factors, and participants' perceptions concerning appropriate responses during an MI event. Results The majority of participants recognized chest pain and shortness of breath as MI symptoms, with a percentage of 87.1% and 86%, respectively. Risk factors awareness was substantial at 90.3% for smoking and 76.1% for obesity. The mean overall awareness score was 26.6±7.5, and around 36% were aware of both symptoms and risk factors. Higher education levels were positively associated with both risk factors and symptom awareness, while employment status showed negative associations with both. Higher-income correlated with greater risk factors awareness. Gender remained significant, with males exhibiting a lower awareness of risk factors and symptoms. Region and chronic disease status were positively associated with risk factors and symptom awareness. More than 90% of participants perceived going to the emergency room immediately if they recognized an MI attack. Conclusion This study highlights the necessity for inclusive awareness campaigns to enhance the identification of MI symptoms and risk factors in Saudi Arabia. It should focus on groups with limited awareness, such as males, employed and retired individuals, and specific pronounced regional disparities.
