Filter by:In this study the investigators retrospectively and prospectively collect information from enrolled subjects undergoing CCTA and evaluate the association of cardiac and non-cardiac imaging with laboratory markers and clinical data including outcome.
Discovered thousands of years ago, coffee is among the most consumed beverages in the world. The relationship between coffee and cardiovascular risk, more specifically coronary artery disease, is controversial. Platelet aggregation and its relationship with coffee is also controversial. The investigators propose this study to evaluate the relationship between coffee and platelet aggregability in patients with coronary artery disease.
The investigators evaluate the effects of intracoronary and intravenous administration of nicorandil on cardiac sympathetic nerve activity and distribution in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention
High-dose statins can reduce mortality and cardiovascular events in patients with established atherosclerotic cardiovascular disease (ASCVD). Therefore, US and European recommendations recommend that established ASCVD patients (coronary artery disease, cerebrovascular disease, peripheral vascular disease) use high-dose statins to lower LDL cholesterol levels by at least 50%. However, in actual practice, high-dose statins are relatively less used, and the reason is unclear, but it is believed to be due to concerns about the side effects of high-dose statins. Most of the side effects of statins are statin-associated muscle symptoms (SAMS), which are more common than the incidence in clinical studies, especially in frontline care. These muscle side effects are dose-dependent and are common at high doses, and the incidence is known to increase in the elderly over 70 years of age. However, the US recommendation recommends using high-dose statins to lower LDL cholesterol by 50% or more to prevent cardiovascular events even in ASCVD patients over 70 years of age. Most early studies on lowering LDL cholesterol in ASCVD patients used high doses of statins. However, after introducing cholesterol absorption inhibitors ezetimibe and PCSK9 inhibitor, large-scale clinical studies have been conducted to lower LDL cholesterol using these drugs. In this study, as in the statin study, cardiovascular events were significantly reduced, and together with statins, it became a standard treatment for ASCVD patients. On the other hand, the clinical benefit shown in clinical studies using cholesterol-lowering agents so far depends entirely on how much LDL cholesterol is lowered and how long it is maintained in a low state, indicating that LDL cholesterol management is the core of arteriosclerosis treatment. In addition to high-dose statins, a combination of low-dose statins and ezetimibe can be cited as a method for lowering LDL cholesterol to more than 50%. In the latter case, it is expected that there will be an advantage of reducing muscle side effects by reaching the target LDL cholesterol level by using a low-dose statin. However, no studies compare the difference in muscle side effects between low-dose statins and ezetimibe combination drugs, which reduce LDL cholesterol to the same extent compared to high-dose statins, in elderly patients over 70 years of age with ASCVD. In this study, the association of low-dose rosuvastatin 5mg and ezetimibe combination (rosuvastatin 10/5mg) compared to high-dose rosuvastatin 20mg in elderly patients 70 years of age or older with established ASCVD. This study aims to compare and analyze the incidence of muscle symptoms (SAMS) and their effect on LDL cholesterol.
The purpose of this study is to assess the safety and tolerability of IMB-1018972 in subjects with obstructive CAD and inducible ischemia.
This study is to evaluation the efficacy and safety of Zotarolimus-Eluting Stent in patients with long coronary artery disease of 25 mm or longer.
The study aim is to evaluate whether DPP4-inhibitor could reduce coronary atherosclerosis assessed by CT scan in patients receiving insulin for diabetes mellitus. In this retrospective study, change in coronary calcium burden between two coronary CT scan will be compared in patients with and without receiving DPP4-inhibitor.
Ischemic mitral regurgitation (MR) and coronary artery disease is common and associated with significant morbidity and mortality. Ischemic MR has been traditionally treated surgically through either valve repair or replacement at the time of concomitant bypass grafting. Although patients with ischemic MR represent a heterogeneous group, outcomes for these patients over the intermediate term is poor owing to left ventricle (LV) dysfunction causing MR and the presence of coronary disease, which portends poor survival. There is an emergence of percutaneous therapies to treat MR which have been shown to be a less invasive, safe, and viable approach to treat comorbid patients. The decision to treat ischemic MR either surgically or percutaneously is influenced by the presence of coronary disease and the ability to provide adequate revascularization. Mitral valve surgery concomitant to surgical revascularization, however, is associated with a several fold increase in mortality. In fact, the incremental risk increase is further magnified in high-risk patients. We therefore propose a novel prospective study to guide intervention for ischemic MR. Patients will be randomized to undergo surgical therapy with either mitral repair/replacement and/or concomitant coronary artery bypass grafting OR percutaneous mitral repair, followed by the ideal Heart Team determined mode of revascularization with either percutaneous coronary intervention or coronary artery bypass grafting.
In Invasive Coronary Angiography there are multiple invasively obtained measurements to determine the funcitonal significance of Cornary Artery Disease. In this Registry, patients who have undergone Invasive Coronary Angiography or Percutaneous Coronary Intervention are included to investigate diagnostic and prognostic implications of the invasive measurements.
This is a prospective, multicenter, self-control clinical trial. 318 patients who need selective operation to evaluate the function of coronary artery were selected and measured with AccuFFRangio Plus and FFR. The data of the experimental group was defined as: FFR value at the distal end of stenosis was obtained by calculating the original X-ray angiographic images of the coronary arteries before operation with the non-invasive blood flow reserve analysis software of Hangzhou ArteryFlow Technology Co., Ltd. The gold standard group data is the clinical measured FFR (clinical gold standard) at the stenosis lesions. It is defined that when the coronary artery reaches the maximum congestion state, the pressure value at the distal end of the stenosis lesions is accurately measured by the guide wire with a pressure sensor, and the ratio value with the coronary mouth pressure is the FFR. By comparing the data of the experimental group and the data of the gold standard group, the effectiveness and safety of the devices in the experimental group were evaluated.
