Filter by:It is well known fact, that prediabetes is a predictor of high cardiovascular mortality, increasing the risk of developing such adverse cardiovascular events as myocardial infarction, stroke and sudden cardiac death. The key pathogenetic link in development of carbohydrates metabolism disorders (CMD) is insulin resistance (IR), which is one of the crucial mechanisms for the development and progression of chronic heart failure (CHF). IR disrupts the functioning of the myocardium due to endothelial dysfunction, inflammation, oxidative stress, remodeling and impaired myocardial metabolism. In condition of a combination of CMD and CHF the reverse development of hyperglycemia is also difficult due to hyperactivation of neurohormonal systems - renin-angiotensin-aldosterone system, in particular. So, drug therapy should neutralize the undesirable metabolic effects of hyperglycemia on the course of CHF, as well as prevent the development of micro- and macrovascular complications. The study will investigate the ability of metformin to impact on clinical and laboratory (neurohormonal, lipid profiles, renal function) parameters of ischemic etiology heart failure patients with prediabetes, as well as their quality of life and prognosis (incidence of adverse cardiovascular events). These tests will be assessed at the beginning and repeated after one year. At the end of the study we will investigate the difference between lifestyle modification effect and metformin treatment. The study is funded by Ministry of Education and Science of Kyrgyz Republic.
Background: Diabetes, and especially diabetic kidney disease is associated with the development of cardiovascular disease such as calcification in the coronary arteries and heart failure. Sleep apnea is frequent among patients with diabetes and diabetic kidney disease and sleep apnea itself is a solitary risk factor in the development of cardiovascular disease. Nonetheless, sleep apnea is underdiagnosed in diabetes patients because of a discrepancy between sleep apnea severity and actual oxygen deficiency symptoms which makes the diagnosis difficult. For that reason, many diabetics have undiagnosed sleep apnea together with cardiovascular disease. Early discovery of sleep apnea among high risk diabetic patients may therefore be considered crucial before cardiovascular complications develop. For this reason, sleep apnea screening of high-risk diabetics can possibly improve early diagnostics of cardiovascular disease. Aim: This study will seek to establish the association between obstructive sleep apnea (OSA) and coronary calcification and heart failure in patients with diabetic kidney disease. The basic hypothesis of the study is that patients with diabetic kidney disease and concurrent OSA have a higher prevalence and severity of coronary calcification and heart failure compared to patients without OSA. Methods: Diabetic adult patients with scheduled check-ups at Steno Diabetes Center Aarhus, or Department of Renal Medicine on Aarhus University Hospital will be included in the study. Firstly, all included patients are screened for sleep apnea with the devices SomnoTouch® and ApneaLink®. Based on the sleep apnea determination; 40 patients with moderate-severe sleep apnea are compared with 40 patients without sleep apnea. In both groups, the patients are examined for calcification in the coronary vessels using a CT-scan while the function of the heart is examined by ultrasound (echocardiography). The stiffness of aorta is measured and performed using radial artery tonometry (SphygmoCor®). Furthermore, range of blood- and urine samples will be performed The perspectives are that patients with diabetes should be regularly evaluated for sleep apnea and that patients with moderate/severe sleep apnea should undergo further examination for cardiovascular disease even though the patients don't display any symptoms of either cardiovascular disease or sleep apnea.
Atrial fibrillation (AF) is the most common cardiac arrhythmia associated with excessive risk of ischemic stroke and heart failure as well as reduced life expectancy. On the other hand, chronic coronary syndromes (CCS) remains the main cause of morbidity and mortality in an aging population. Both disease entities share common risk factors such as hypertension, diabetes and obesity The purpose of the study is to investigate the hypothesis indicating lack of significant coronary lesions in AF vs. sinus rhythm (SR) patients.

Valvular heart diseases are significant problem in Polish population. Coexistence of coronary artery disease in patients with VHD increases the risk of death and affects further therapeutic strategy. The aim of the study is analysis the epidemiology and the long-term prognosis among patients with VHD.
Cardiovascular disease (CVD) is one of the leading causes of death in the Western Society. Patients with type 2 diabetes mellitus (T2DM) or dysglycemia have an increased risk of developing CVD. Furthermore, T2DM have an increased risk of developing heart failure, especially non-systolic, whether or not this is correlated to stepwise abnormal glycemic status is not fully investigated. The aims of this study are to investigate association between 1) Coronary plaque burden and morphology to glycemic status (normal glucose tolerance (NGT), dysglycemia (impaired fasting glucose (IFG) or impaired glucose tolerance (IGT)) and diabetic oral glucose tolerance test (OGTT) in participants without known T2DM), 2) Coronary plaque burden and morphology to diastolic and systolic function of the left ventricle including 2D speckle-tracking assessments, 3) Glycemic status to diastolic and systolic function of the left ventricle including 2D speckle-tracking assessments In this descriptive study, 500-800 asymptomatic men aged 65-75 without known diabetes will be included and divided into three subpopulations according to glycemic status. Blood sample, oral glucose tolerance test (OGTT), echocardiography and Coronary CT Angiography (CCTA) will be performed at inclusion
Introduction: Diabetes Mellitus (DM) is a condition known to be associated with coronary artery disease (CAD) and its role as promoter of atherosclerosis is well stablished. The revascularization surgery is commonly indicated to patients with multivessel coronary disease and kidney injury is a prevalent complication in post operation. This work aims to evaluate the impact of a strategy to control Diabetes Mellitus using inhibitors of sodium-glucose cotransporters (ISGLT2) in diabetics patients with assigned myocardial revascularization with cardiopulmonary bypass
Major cardiovascular surgery is associated with postoperative cognitive decline (POCD), with a deterioration in memory, attention and speed of information processing. A multifactorial pathophysiology is presumed but this study focuses on the role of (neuro)inflammation in the development of POCD after coronary artery bypass grafting (CABG) surgery.
The purpose of this study is to assess the safety, efficacy and optimal dose of TSG-01, an innovative drug with ginsenosides as its main components, in the treatment of patients with chronic heart failure(CHF). Preclinical studies have revealed that TSG-01 promote myocardial energy metabolism and ATP production, reduce the damage of human pulmonary microvascular endothelial cell connection, resist arrhythmia, and regulate the lipid metabolism disorder caused by myocardial ischemia. Results from CHF animal models(dog, rat) showed that TSG-01 significantly increase coronary blood supply, improve myocardial contractility, reduce heart expansion and pulmonary edema. Besides its potency of improving heart function, TSG-01 was found to induce diuresis without obvious effect on urine potassium in rats. TSG-01 has been approved by CFDA for a clinical trial on the treatment of CHF (Approval No. 2018L03012). A randomized, double-blind, multicenter, placebo-controlled phase IIa clinical trial is now being conducted in 5 hospitals in China. A total of 90 cases of CHF caused by coronary heart disease are included and randomly divided into three groups: high-dose, low-dose of TSG-01 and placebo group. NYHA functional class, 6-minute walk test(6MHWT) distance, NT-proBNP, left ventricular ejection fraction(LVEF), echocardiographic parameters (LVESV, LVEDV, and heart size) and MLHFQ score are measured before, during and after treatment to evaluate the benefits of TSG-01 therapy in patients with CHF.
Being easy, bedside, non-expensive, noninvasive and radiation free, there has been a growing interest in the implementation of lung ultrasound in critical care management in the last decade, cardiac surgery was not an exception in both adult and pediatric surgeries Many predictors for open heart surgery outcomes have been studied in past years including The Society of Thoracic Surgeons (STS) risk score and the EuroSCORE (ES), preoperative clinical condition, associated chronic diseases, type of surgery, age, duration of cardiopulmonary bypass and brain natriuretic peptide (BNP), cystatin-C A recent study described the use of a novel postoperative lung ultrasound score scanning for B lines which denote subpleural interstitial edema in various lung regions for predicting critical care length of stay in pediatric cardiac surgeries. The objective of the current study is to evaluate the role of the new lung ultrasound score in predicting the length of postoperative intensive care stay after adult open heart surgeries.
