AIM: The aim of the study was to analyse the correlation between maternally expressed gene 3 (MEG3) expression and heart rate variability (HRV) in heart failure patients with ventricular arrhythmia (VA). METHODS: A total of 130 heart failure patients, treated from July 2018 to March 2021, were prospectively selected and divided into a non-VA group ( n = 85) and a VA group ( n = 45) according to the presence or absence of VA. The correlations of serum MEG3 expression and HRV with cardiac function indicators were investigated by Pearson correlation analysis...

BACKGROUND: Abdominal aortic calcification (AAC) is considered an independent predictor of cardiovascular morbidity and mortality. Klotho, an anti-aging gene, has cardiovascular protective effects. At present, the association between klotho and AAC in the general population is uncertain. We investigated the relationship between serum soluble α-klotho (SSKL) and AAC in 2 327 participants from the National Health and Nutrition Examination Survey. METHODS: To estimate the association between log-transformed SSKL (lnSSKL) and AAC, multivariate logistic regression analyses were conducted...

We aimed to assess the echocardiographic parameters of cardiac structure and function in patients with heart failure with preserved ejection fraction (HFpEF) and atrial fibrillation (AF). Thirty-seven HFpEF patients with AF were selected, while 38 patients with simple HFpEF in the same period were selected as controls. Three-dimensional speckle-tracking echocardiography was performed on both groups and the parameters were compared. The early diastolic longitudinal peak strain rates [early diastolic longitudinal strain rate (LSRE ), early diastolic circumferential strain rate (CSRE ), early diastolic radial strain rate (RSRE ) and early diastolic rotational strain rate (RotRE )], late diastolic longitudinal peak strain rates (LSRA , CSRA , RSRA and RotRA ) and untwisting parameters [untwisting rate during isovolumic relaxation time (UTRIVR ) and early peak untwisting rate (UTRE )] were all negatively correlated with the ratio of early diastolic transmitral velocity to early diastolic mitral annular velocity ( E/E') ( p < 0...

OBJECTIVE: The aim of this study was to determine adiponectin and copeptin levels that might be prognostic for cardiovascular mortality (CvsM) in ST-segment elevation myocardial infarction (STEMI) patients who had percutaneous coronary intervention (PCI). METHODS: Patients who underwent PCI between November 2010 and April 2011 were enrolled and followed for more than eight years. The baseline, demographic and angiographic findings, in-hospital follow up, laboratory results including adiponectin and copeptin levels, and echocardiographic data of the patients were evaluated...

BACKGROUND: Heart failure is a major cause of global morbidity and mortality. Studies in laboratory animals have shown the direct protective effects of α-klotho on the cardiovascular system although it has limited expression in the heart. The association between α-klotho and cardiovascular disease is still controversial in different clinical studies. We designed a cross-sectional study in order to investigate the association between serum α-klotho level and the prevalence of heart failure in the American general population...

Heart rate variability is a non-invasive method of assessing global health through the analysis of the autonomous centralnervous system, including both the sympathetic and parasympathetic systems. The aim of this study was to evaluate the effect of resistance training on heart rate variability at rest in elderly individuals undergoing six months of resistance training with progressive loads. Training reduced the body fat percentage of the volunteers (pre: 39.39 ± 7.21 vs post: 34.97 ± 6.40%; p = 0...

INTRODUCTION: Fractional flow reserve (FFR) assessment compares the blood flow on either side of a blockage in the coronary artery and indicates how severe the stenosis is in the artery. Intravenous adenosine is widely used to achieve conditions of stable hyperaemia for the measurement of FR. However, intravenous adenosine affects both systemic and coronary vascular beds differentially. Therefore, FFR has some limitations, such as the side effects of adenosine and the long procedure time...

OBJECTIVES: The optimal choice of surgery in coarctation of the aorta (CoA) remains controversial but it needs to be individualised. However, in most conditions, a surgical approach through thoracotomy maintains adequate exposure to create aortic patency. This study aimed to assess the efficiency and reliability of thoracal approaches in the treatment of CoA by examining the mid- and late-term outcomes, and determining the predictive factors for re-intervention. METHODS: Patients who underwent CoA repair through thoracotomy between September 2015 and February 2023 were included in the study, except for those with complex cardiac diseases...

BACKGROUND: Cardiovascular disease is the leading cause of mortality worldwide, with dyslipidaemia being one of the major risk factors. Point-of-care testing (POCT) allows for the rapid measurement of serum lipids. The aim of this study was to assess the accuracy of serum lipid measurement by the Fujifilm™ NX700 POCT compared to a gold-standard clinical laboratory method (Medpace, Leuven, Belgium). METHODS: This was a prospective, observational study conducted at the Lipid Clinic at Charlotte Maxeke Johannesburg Academic Hospital from July to September 2022...

BACKGROUND: Lipoprotein(a) [Lp(a) ] is associated with coronary artery disease due to its atherogenic and thrombogenic nature. In this study, we aimed to compare the level of Lp(a) in young and middle-aged patients with ST-elevation myocardial infarction (STEMI). METHODS: This retrospective study included 287 patients aged 20-65 years who presented to the emergency department for the first time due to STEMI. The patients were divided into two groups: 20-45 years (young group, n = 111) and 46-65 years (middle-aged group, n = 176)...

BACKGROUND: The diagnostic and therapeutic efforts instituted by the state of Senegal since the results of the STEPwise survey in 2015 could and should be reinforced with an effective and targeted preventative approach against cardiovascular accidents. This study aimed to (1) identify the pathological population that contains the most incidents of stroke in Senegal, (2) identify the prevalence, and geographical and gender distribution of biological co-morbidities with hypertension, stroke and advice for a change in behaviour, and (3) research the factors associated with the occurrence of cardiovascular accidents specific to the Senegalese context...

BACKGROUND: Antithrombotic therapy in atrial fibrillation is generally managed with the CHA2 DS2 -VASc score. Aortic valve sclerosis (AVS) is a focal thickening of the aortic valve without a restriction of motion. AVS is related to several cardiovascular risk factors. Our study was performed to evaluate whether the presence of AVS was associated with the CHA2 DS2 -VASc score. METHODS: This cross-sectional, observational study comprised 411 patients with AVS grades 1-3 [AVS (+)] and 102 patients with AVS grade 0 [AVS (-)]...

AIM: Recent research has demonstrated that the contractile characteristics of the right ventricular outflow tract (RVOT) play a significant role in right ventricular function. Pulmonary annular motion velocity (PAMVUT) is a reliable marker of RVOT function. Also, combined systolic velocity [PAMVUT added to tricuspid annular systolic velocity (St)] has been revealed as a suitable parameter for right ventricular systolic function. In this study, we examined the association between the severity of the illness in cirrhotic patients and the combined S velocities (CSV)...

AIM: The Shexiang Baoxin pill (SBP) is a commonly used drug for the treatment of coronary artery disease in China. More recently, some studies have found that it improved coronary microvascular function. This study aimed to explore the possible mechanism by which the SBP promotes angiogenesis after acute myocardial infarction (AMI).

BACKGROUND: Graft patency is the most important factor in coronary artery bypass surgery. This study aimed to compare the relationship between three different surgical methods and transit time flow measurement (TTFM), which is used to detect technical problems in anastomoses performed during coronary artery bypass graft operations and to correct them if necessary. METHODS: A total of 110 patients undergoing isolated coronary artery bypass surgery were analysed. Of these patients, 48 were operated on by inducing cardiopulmonary arrest (group 1), 33 were operated on without inducing cardiac arrest (group 2) during cardiopulmonary bypass surgery, and 29 underwent surgery on the off-pump beating heart (group 3)...
