INTRODUCTION: To analyze the blood transfusion factors of minimally invasive direct coronary artery bypass (MIDCAB) surgery using artificial intelligence. METHODS: A retrospective analysis was performed for patients undergoing MIDCAB operations that no heart-lung machine was used from January 2017 to September 2022 in our hospital. The influencing factors of blood transfusion were used to build the artificial intelligence model. Eighty percent of the database was used as the training set, and twenty percent database was used as the testing set...

INTRODUCTION: Heart Failure with Improved Ejection Fraction (HFimpEF) is a recently defined subtype of HF, characterized by an increase in ejection fraction (EF) after a prior diagnosis of reduced EF. There is limited data on the characteristics and outcome of this patient subset. The study aimed to investigate the clinical profile and prognosis of this patient group. METHODS: HFimpEF patients from a large echocardiography database with comprehensive clinical and outcome data were evaluated for clinical characteristics and outcomes including mortality and cardiovascular hospitalizations...

Introduction There has been remarkable progress in both diagnosis and treatment of patients with congenital heart disease (CHD), with an increasing number of survivors. Whether patients with CHD are more likely to develop cancer is still a controversial issue. This study aimed to quantitatively estimate the association between patients with CHD and the risk of developing cancer through meta-analysis. Methods Web of Science, PubMed, and Embase databases were searched from inception to September 2023 to identify potentially relevant case-control studies and cohort studies that reported risk estimates and confidence intervals...

BACKGROUND: Atrial fibrillation (AF) is a common arrhythmia, with radiofrequency catheter ablation (RFCA) being first-line therapy. However, the high rate of post-ablation recurrence necessitates the identification of predictors for recurrence risk. Left atrial low-voltage areas (LA-LVASs), reflecting atrial fibrosis, have been confirmed to be related to recurrence of atrial fibrillation. Recently, epicardial adipose tissue (EAT) has been studied due to its role in initiating and maintaining atrial fibrillation...

INTRODUCTION: Heart failure is a common chronic illness associated with high readmission rates and death. Comprehensive nursing care, management of symptoms, and psychological support are increasingly seen as critical components of successful heart failure therapy. OBJECTIVE: This systematic review and meta-analysis aimed to determine the effect of comprehensive nursing care on clinical outcomes and quality of life in heart failure patients. METHODS: We searched electronic databases (Pubmed, PROSPERO, and Web of Science) for randomised controlled trials and observational studies on comprehensive nursing care treatments for heart failure patients...

INTRODUCTION: Angiotensin-converting enzyme 2 (ACE2) of the renin-angiotensin-aldosterone system (RAAS) serves as a functional receptor to gain entry into the cells for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19). The interaction between SARS-CoV-2 and ACE2 is a potential virulent factor in infectivity. Our study aims to ascertain the association of RAAS inhibitors with adverse cardiovascular and other outcomes in hospitalized COVID-19 patients...

INTRODUCTION: Atrial fibrillation (AF) increases the risk for stroke, dementia and impaired health related quality of life (HRQL). Elective direct current cardioversion (ECV) is often used to restore sinus rhythm, but is associated with thromboembolism. While larger strokes usually produce symptoms, subclinical ones may go unrecognized and may cause cognitive and functional decline over time. In the current study, we sought to evaluate the effects of ECV on silent brain infarctions and HRQL in patients with AF...

<abstract>Coronary artery disease (CAD) affects over 20 million Americans and its' spectrum of impact leads to an estimated 7 million deaths, as well as the loss of 129 million disability-adjusted life years, worldwide, each year. CAD develops as atherosclerotic plaque forms in the coronary arteries. These plaques can eventually limit blood flow to myocardial tissue resulting in ischemia a risk for acute plaque rupture and acute coronary syndrome. While chest pain may represent a wide array of underlying diseases, given the high morbidity and mortality associated with CAD, an ischemic cardiac etiology must always be considered...

Introduction Patients undergoing left atrial appendage occlusion (LAAO) are at increased risk for bleeding or thromboembolic events. Concurrently, biomarkers are of growing importance in risk stratification for atrial fibrillation patients. We aimed to evaluate the association of hematological markers and clinical characteristics with the occurrence of thromboembolic and bleeding events following LAAO. Methods Seven implanting centers retrospectively gathered data on hematological markers (i.e. platelet count (PC), mean platelet volume (MPV), and fibrinogen) prior LAAO...

INTRODUCTION: To investigate the expression and predictive value of NOD-like receptor thermoprotein domain-related protein 3 (NLRP3) in patients with nonvalvular atrial fibrillation (NVAF) with ejection fraction preserved heart failure (HFpEF). METHODS: A retrospective analysis of 121 patients diagnosed with NVAF. According to the occurrence of HFpEF, 81 patients was assigned in the NVAF group and 40 patients in the NVAF/HFpEF group. The levels of NLRP3, B natriuretic peptide (BNP), and interleukin-1β were determined using enzyme-linked immunosorbent assay (ELISA)...

INTRODUCTION: The AIRCARD study is designed to investigate the relationship between long-term exposure to air and noise pollution and cardiovascular disease incidence and mortality. We aim to conduct a robust prospective cohort analysis assessing the cumulative and differential impacts of air and noise pollution exposure on cardiovascular disease and mortality. This study will adjust for relevant confounders, including traditional cardiovascular risk factors, socioeconomic indicators, and lipid-lowering agents...

INTRODUCTION: The prevalence of atrial fibrillation (AF) increases with age. Although most AF cases are caused by irregular electrical impulses near the pulmonary vein, not all elderly individuals develop AF. Moreover, risk factors such as hypertension and diabetes do not always lead to AF, even in severe conditions such as pneumonia. We aimed to examine iron kinetics, including ferritin, in patients with AF and individuals in normal sinus rhythm (NSR) using peripheral blood samples. METHODS: This case-control study included 178atients who visited the outpatient clinic of a cardiovascular and arrhythmia specialist at the National Center for Geriatrics and Gerontology between August and October 2023...

INTRODUCTION: High-molecular-weight (HMW) von Willebrand Factor (VWF) multimer deficiency occurs in classical low-flow, low-gradient (LF/LG) aortic stenosis (AS) due to shear force-induced proteolysis. The prognostic value of HMW VWF multimer deficiency is unknown. Therefore, we sought to evaluate the impact of HMW VWF multimer deficiency on clinical outcome. METHODS: In this prospective research study, a total of 83 patients with classical LF/LG AS were included...

Introduction Cardiovascular disease care is a critical clinical application that necessitates real-time monitoring models. Previous models required the use of multi-lead signals and could not be customized as needed. Traditional methods relied on manually designed supervised algorithms, based on empirical experience, to identify waveform abnormalities and classify diseases, and were incapable of monitoring and alerting abnormalities in individual waveforms. Methods This research reconstructed the vector model for arbitrary leads using the phase space time delay method, enabling the model to arbitrarily combine signals as needed while possessing adaptive denoising capabilities...

BACKGROUND: Cardiovascular disease is the leading cause of morbidity and mortality in the elderly population. Coronary artery disease, heart failure, and peripheral artery disease constitute the prevailing conditions. Cardiac rehabilitation (CR) represents a cornerstone in the secondary prevention of cardiovascular disease, since it has been associated with significant cardiovascular benefits in the above-mentioned conditions, by significantly reducing cardiovascular outcomes and improving functional independence and quality of life...
