Filter by: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.
The purpose of SCADIAB is to assess the real-life efficiency of systematic screening for ischemic heart disease in T2DM patients at very high cardiovascular risk, without known coronary heart disease, from the databases of the National Health Data System (SNDS).
Despite advancements in medical care, ischemic heart disease (IHD) remains the leading global cause of death. IHD develops through lipid accumulation into the coronary arteries with subsequent formation of larger atherogenic plaques. During myocardial infarction (MI), a plaque ruptures and subsequent occlusion leads to a death of the heart muscle. The tissue is rapidly replaced with a scar, which may later lead to heart failure (HF). Optimally, disease biomarkers are analyzed from blood, provide insight into the disease progression and aid the evaluation of therapy efficacy. Unfortunately, no optimal biomarkers have been identified for IHD. The vast but uncounted number of patients with undiagnosed IHD, benefitting from an early diagnosis, underscore the dire need for an IHD biomarker. Epitranscriptomics, the study of posttranscriptional modifications on RNA, has recently been properly re-established. This expanding field is uncovering a new layer of regulation, controlling processes ranging from cell division to cell death. Over 170 modifications have been identified as posttranscriptional marks in RNA species. These modifications influence RNA metabolism, including export, stability, and translation. One the most common and intensively studied RNA modification is the N6-methyladenosine (m6A), the abundance and effects of which are determined by the interplay between its writers, readers and erasers. Recent findings suggest a local dysregulation of the m6A dynamics in the myocardium, coalescing in signalling pathway and contractility related RNA transcripts during hypertrophy, MI and HF. While these early reports have focused on the myocardium, the role of the m6A in the circulation during IHD remains unexplored. We hypothesize the IHD pathophysiology to be reflected in the epitranscriptome of the circulating RNA. The objective of the IHD-EPITRAN is to identify new IHD biomarkers via cohort comparison of the blood epitranscriptomes from patients with: (1) MI related with coronary angioplasty, (2) IHD treated with elective coronary artery bypass grafting, (3) aortic valve stenosis treated with valve replacement and (4) IHD-healthy controls verified with computerized tomography imaging. The RNA fractionation is followed by the quantitative modifications analysis with mass spectrometry. Ultimately, nanopore RNA sequencing with simultaneous m6A identification in their native sequences is carried out using recently published artificial intelligence-based algorithm.
To evaluate the clinical efficacy of Ginkgo biloba dropping pills on improving the frequency of angina pectoris and the life quality of patients with stable angina pectoris and depression symptoms on the basis of the best western medicine treatment; Study on the clinical pharmacological mechanism of Ginkgo biloba dropping pills.
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.

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
The investigators hypothesized that the CRP/troponin ratio measured in patients presenting to the ED with elevated troponin levels could differentiate between patients with cardiac ischemia and those who present due to a systemic inflammatory or infectious disease. The aim of the study was to determine the necessary CRP/troponin ratio required to rule out cardiac ischemia in a large ED population and determine its impact on long-term prognosis.
Olive extracts are considered to have antioxidant properties. The investigators will study the effect of olive extracts containing hydroxytyrosol (HT)-olivomed and combination of Oleuropein (OL), Hydroxytyrosol (HT), Oleocanthal (OC) - olivomedSmart on endothelial, cardiac and vascular function in patients with coronary artery disease .
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.
