Filter by:The aim of study is to examine the relationship between lipid subfractions, inflammation and structural-functional properties of the arterial wall in patients with premature coronary heart disease, to study genetic polymorphisms that determine lipid subfractions concentration on the functional and morphological properties of the arterial vascular wall in patients with early coronary heart disease, to study the effect of alirocumab and evolocumab on lipid subfractions, inflammation and structural-functional properties of arterial wall in patients with early coronary atherosclerosis and to study the influence of NOS-3 gene expression on the functional and morphological properties of the arterial vascular wall in the same patients. Impaired blood fat metabolism and chronic inflammation are intertwined as possible causes of atherosclerosis. Lipoprotein (a) (Lp (a)) is an important risk factor for coronary heart disease and a prognostic predictor in patients after myocardial infarction, but recent research suggests that subtilisin-kexin convertase type 9 (PCSK9) inhibitors are the only drugs that significantly reduce serum Lp (a) concentration. However, there are no data on the relationship between Lp (a) values and polymorphisms for Lp (a), indicators of inflammation and impaired arterial function, and response to treatment with various PCSK9 inhibitors in patients with early coronary heart disease.
This is a multi-center study conducted at 13 sites in 3 countries (Singapore, New Zealand, and the Australia). Approximately 260 patients with an acute myocardial infarction (AMI) will be randomized in a ratio of 1:1 ratio to receive AZD5718 125 mg or placebo for 12 months.
This is a prospective observational clinical trail which will recruit 1000-1500 participants over 65 years with frailty and acute coronary syndrome (ACS) in Beijing Friendship hospital. The investigators will conduct frailty assessment (FRAIL scale, CFS, SPPB), comorbidities, functional status (Barthel index, ADL, IADL), nutritional risk (MNA-SF), and then observe the clinical outcomes of elderly ACS participants with frailty. Then, the investigators will follow-up these participants separately in 1,3,6 and 12months, the anticipate follow-up time is 1 year. According to the follow-up results, investigators will evaluate the impact of frailty and other senile syndromes on the short-term and long-term prognosis of ACS, and develop a scoring system for the prognosis evaluation of elderly ACS participants.
The study aimed to evaluate the association between the obesity grade and the age of the first acute coronary syndrome (ACS). The effect of cardiovascular (CV) risk factors and the age of first ACS in patients with severe obesity was also examined. Consecutive patients with diagnosis of first episode of ACS were prospectively enrolled in 2014 to 2024.Cardiovascular risks of patients will be determined according to clinical and laboratory evaluation and patients were categorized by their body mass indices (BMI). Independent variables that effected the age of first ACS were examined by linear regression analysis
The study aims to determine the pharmacodynamic performance in the first hour measured with verifynow, of the conventional ticagrelor loaded dose versus chewed ticagrelor in patients with acute coronary syndrome treated with percutaneous coronary intervention
The use of beta blockers after acute myocardial infarction is a core component of drug therapy, but evidence is primarily derived from patients who did not receive reperfusion therapy and secondary prophylaxis.In contemporary times, the prognostic value of beta blockers in patients with acute myocardial infarction has been questioned, particularly in patients without reduced heart failure/ejection fraction after acute myocardial infarction.
The purpose of this study is to develop a quality improvement intervention to address barriers to evidence-based acute coronary syndrome (ACS) care in northern Tanzania. Patients who presented to Kilimanjaro Christian Medical Center (KCMC) will be asked to complete a survey about barriers and facilitators of health care. In addition the survey will be administered to all providers, policymakers, and administrators participating in in-depth interviews. Data from this survey will be used to develop a quality improvement intervention that will be piloted by KCMC staff. Six months after the pilot program is implemented providers, patients, and administrators will be interviewed for their perspectives on the program.
The primary objective of the study aims to evaluate frequence of acute renal insufficiency in patients with ST-segment elevation who need urgent coronary angiography in Ambroise Paré hospital. The secondary objectives are: - identify factors of risks associated with the occurrence of acute renal insufficiency after coronarography. - establish a preprocedure score, predicting of acute renal insufficiency after urgent coronary angiography in patients with ST+ acute coronary syndrome.
The purpose of this study is to evaluate analgesic efficacy of inhaled methoxyflurane vs intravenous morphine in patients presenting with acute ST-elevation (STEMI) / non ST-elevation acute coronary syndrome (NSTE-ACS)
The optimal antithrombotic management in patients with coronary artery disease (CAD) and concomitant atrial fibrillation (AF) is unknown. AF patients are treated with oral anticoagulation (OAC) to prevent ischemic stroke and systemic embolism and patients undergoing percutaneous coronary intervention (PCI) are treated with dual antiplatelet therapy (DAPT), i.e. aspirin plus P2Y12 inhibitor, to prevent stent thrombosis (ST) and myocardial infarction (MI). Patients with AF undergoing PCI were traditionally treated with triple antithrombotic therapy (TAT, i.e. OAC plus aspirin and P2Y12 inhibitor) to prevent ischemic complications. However, TAT doubles or even triples the risk of major bleeding complications. More recently, several clinical studies demonstrated that omitting aspirin, a strategy known as dual antithrombotic therapy (DAT) is safer compared to TAT with comparable efficacy. However, pooled evidence from recent meta-analyses suggests that patients treated with DAT are at increased risk of MI and ST. Insights from the AUGUSTUS trial showed that aspirin added to OAC and clopidogrel for 30 days, but not thereafter, resulted in fewer severe ischemic events. This finding emphasizes the relevance of early aspirin administration on ischemic benefit, also reflected in the current ESC guideline. However, because we consider the bleeding risk of TAT unacceptably high, we propose to use a short course of DAPT (omitting OAC for 1 month). There is evidence from the BRIDGE study that a short period of omitting OAC is safe in patients with AF. In this study, these patients are treated with DAPT, which also prevents stroke, albeit not as effective as OAC. This temporary interruption of OAC will allow aspirin treatment in the first month post-PCI where the risk of both bleeding and stent thrombosis is greatest. The WOEST 3 trial is a multicentre, open-label, randomised controlled trial investigating the safety and efficacy of one month DAPT compared to guideline-directed therapy consisting of OAC and P2Y12 inhibitor combined with aspirin up to 30 days. We hypothesise that the use of short course DAPT is superior in bleeding and non-inferior in preventing ischemic events. The primary safety endpoint is major or clinically relevant non-major bleeding as defined by the ISTH at 6 weeks after PCI. The primary efficacy endpoint is a composite of all-cause death, myocardial infarction, stroke, systemic embolism, or stent thrombosis at 6 weeks after PCI.
