Objectives: Chemotherapy improves survival in breast cancer patients but increases the risk of myocardial dysfunction and heart failure. Since early prediction cardiomyopathy remains difficult, biomarkers are needed for detecting damage before failure develops. This study examines association between oxidative stress a chemotherapy-induced rat model. Methods: Forty-two rats were randomized into four groups: control (n = 7), doxorubicin only plus trastuzumab with cardioprotective intervention...
Abstract Early identification of women at high risk for cardiovascular diseases (CVD), with subsequent monitoring, will allow improved clinical outcomes and generally better quality life. This study aimed to identify the associations between early menopause, abnormal diastolic function, outcomes. retrospective included 795 menopausal from is a nationwide, multicenter, registry patients suspected angina visiting outpatient clinic. The into two groups: normal menopause (menopausal age ≤ 45...
Several regression-based models for predicting outcomes after acute myocardial infarction (AMI) have been developed. However, prediction that encompass diverse patient-related factors over time are limited. This study aimed to develop a machine learning-based model predict longitudinal AMI. was based on nationwide prospective registry of AMI in Korea ( n = 13,104). Seventy-seven predictor candidates from prehospitalization 1 year follow-up were included, and six learning approaches analyzed....
Abstract Acute myocardial infarction (AMI) is highly prevalent and remains the leading cause of mortality. Particularly in women, under-recognition management AMI have been raised. The aim this study was to investigate long-term trends prevalence, treatment methodologies, mortality by gender. subjects were patients hospitalized for according Korean National Health Insurance Claims Database from 2002 2018. Total 633,097 hospitalized, 40% women. incidence has increasing since 2011, with a...
Although some peripartum-associated cardiomyopathy patients present with features that are clinically and echocardiographically similar to those of takotsubo (TCM), little is known about the diagnosis clinical course peripartum TCM.In a tertiary hospital in Seoul, Korea, we searched database find cases were associated pregnancy from January 1995 May 2019. Applying published diagnostic criteria, sought (PPCM) TCM for comparison. Of 31 pregnancy-associated patients, 10 21 PPCM found. Maternal...
Abstract Aims Although evaluation of left ventricular ejection fraction (LVEF) is crucial for deciding the rate control strategy in patients with atrial fibrillation (AF), real-time assessment LVEF limited outpatient settings. We aimed to investigate performance artificial intelligence–based algorithms predicting LV systolic dysfunction (LVSD) AF and rapid response (RVR). Methods results This study an external validation a pre-existing deep learning algorithm based on residual neural network...
Abstract Background Vasospastic angina (VSA) is characterized by coronary spasm, which can be aggravated vasoactive substances such as serotonin. Hypothesis Sarpogrelate, a selective serotonin receptor antagonist, and high‐dose statin have some effects on the reduction of spasm in patients with VSA. Methods We recruited 100 angiographically confirmed VSA, randomly assigned them into four groups: sarpogrelate (Group A, n = 25), low‐dose or no B, placebo C, D, 25). The primary endpoint was...
Abstract Aims Chemotherapy-induced cardiotoxicity (CIC) is a significant complication, meanwhile myocardial damage might differ depending on chemotherapy agents and their timing. The aim of this study was to evaluate serial changes layer-specific function in patients with breast cancer differences by the development time CIC agent. Methods results A total 105 consecutive (age: 52.3 ± 9.3 years) were enrolled. occurred 20 (19%) during 6 months. Endocardial midmyocardial functions decreased or...
We aimed to examine the prevalence of burnout among imaging cardiologists in Korea and identify its associated factors. An online survey affiliated with university hospitals was conducted using SurveyMonkey® November 2023. The validated Korean version Maslach Burnout Inventory-Human Service Survey used assess across three dimensions: emotional exhaustion, depersonalization, lack personal accomplishment. Data on demographics, work environment factors, job satisfaction were collected...
This study aimed to identify risk factors associated with the implementation of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in patients acute myocarditis and develop a predictive model.
Data are limited on the clinical manifestations and outcomes of acute myocarditis from a large-scale registry. We investigated myocarditis's characteristics prognosis large-scale, multi-center registry in Republic Korea. collected data seven hospitals between 2001 2021. Clinical variables during index hospitalization follow-up periods were analyzed. also evaluated inter-center temporal differences diagnostic treatment patterns. Eight hundred forty-one patients diagnosed with included. Common...
Coronary microvascular dysfunction (CMD) is one of the mechanisms myocardial ischemia and left ventricular (LV) diastolic dysfunction, which closely related to heart failure with preserved ejection fraction (HFpEF). Frailty, associated sarcopenia, often accompanied by HFpEF. In present study, we aim evaluate relationship between CMD, body composition, cardiopulmonary exercise capacity in patients suspected We will enroll experiencing chest symptoms (chest pain or dyspnea) an indication...
Abstract Aims This study evaluated the sex differences of sequential changes in coronary blood flows and microvascular function patients with suspected angina but no obstructed arteries. Methods A total 202 consecutive who experienced chest pain had significant artery stenosis underwent adenosine stress echocardiography were included study. Coronary flow (CBF) velocities measured at 1, 2, 3 min after infusion. Results The mean age was 61 years, 138 (68%) women. Approximately 40% dysfunction...
Sinus of Valsalva aneurysm (SVA), is a rare disease that may occur not only secondary to congenital or systemic diseases, but can also be related acquired diseases such as aortic dissection, infection, and trauma. We report case SVA presented fever. made fairly accurate diagnosis aneurysmal perforation into the right ventricle from complicated infective endocarditis using multimodality imaging tools, including transthoracic, transesophageal echocardiography computed tomography. With regard...
