Filter by:Patients with type 2 diabetes mellitus (DM) have higher risk of major cardiovascular events (MACE) and renal disfunction. The Sodium-glucose cotransporter-2 inhibitors (iSGLT2) reduces hyperglycemia in patients with type 2 DM and have multiple metabolic effects, lowering primary composite cardiovascular outcomes and progression to renal failure. 25% of patients with Stable Ischemic Heart Disease (SIHD) undergoing PCI are diabetics being one of the most prevalent and important risk factors for the development of contrast induced nephropathy (CIN). The occurence of CIN is associated with higher rates of death, loss of renal function, necessity of dialysis and increase of health care costs. In this pilot study we sought to evaluate if the iSGLT2 would prevent periprocedural complications - such as periprocedural CIN and MI - in type 2 DM patients undergoing PCI through the assessment of renal and myocardial biomarkers
In this study, quantitative characterization of plaque using coronary computed tomographic angiography (CTA) will be used to determine if women who were treated with intensive medical therapy have a greater reduction in the amount and type of cholesterol plaque compared to women receiving usual care and if this results in beneficial changes in clinical symptoms. The study will provide an understanding of how intensive medical therapy works in providing clinical benefit in women with nonobstructive plaque.
MACCHUS is a randomized, single-center, controlled, cross-over interventional study in which coronary artery resistances will be measured at baseline and during temporary occlusion of the coronary sinus.
The DESyne BDS Plus Randomized Clinical Study is a prospective, multi-center, single blind, randomized clinical study. Randomization (1:1; DESyne BDS Plus : DESyne X2) of up to 100 patients (50 in each arm) requiring treatment of up to two de novo coronary artery lesions ≤ 34 mm in length in vessels ≥ 2.25 mm and ≤ 3.5 mm in diameter will be conducted. Clinical endpoints will be assessed at each follow-up point: 3 days or hospital discharge (whichever comes first), 1, 6, and 12 months.
This is a single-center, prospective, controlled and diagnostic clinical trial which will enroll 30 patients scheduled for coronary angiography in China.Patients will receive contrast-enhanced cardiac magnetic resonance with polysaccharide superparamagnetic iron oxide nanoparticle before percutaneous coronary angiography.In order to evaluate the safety of polysaccharide superparamagnetic iron oxide nanoparticle, patients will detect iron levels in peripheral and tissue before and after the examination.The main indicators of the study are the degree of coronary artery stenosis and the stability of coronary atherosclerotic plaque assessed by contrast-enhanced cardiac magnetic resonance with polysaccharide superparamagnetic iron oxide nanoparticle.
Among patients with ischemic heart disease who are referred for coronary angiography, a substantial proportion have non-obstructive coronary artery disease (CAD). Myocardial infarction (MI) with non-obstructive coronary artery disease (MINOCA) accounts for 5-20% of patients with MI and preferentially affects women. MINOCA pathogenesis is varied and may include atherosclerotic plaque rupture, plaque erosion with thrombosis, vasospasm, embolization, dissection or a combination of mechanisms. Other patients may have clinically unrecognized myocarditis, or takotsubo syndrome masquerading as MI. Among patients referred for coronary angiography for the evaluation of stable ischemic heart disease, non-obstructive CAD is present in up to ~30% of men and ~60% of women. Stable ischemia with non-obstructive coronary arteries (INOCA) may be due to coronary microvascular dysfunction in up to 40% of these patients. Our understanding of mechanisms of MINOCA and INOCA remain incomplete. Coronary inflammation has been hypothesized as a potential mechanism contributing to coronary spasm in MINOCA and microvascular disease in INOCA.
Open-label, randomized, cross-over study conducted in a single center, applied to patients receiving a polypill with 100 mg of acetyl salicylic acid and different doses of ramipril and atorvastatin for indication of secondary prevention according to clinical practice, with objective of analyzing the level of systolic blood pressure and LDL-cholesterol in the same patient in 2 different periods: one under treatment of 3 months with the polypill and another of 3 months with the components separately.
PROTEUS is a multicentre, two arm, randomised controlled trial of a medical device to assess the impact of the introduction of EchoGo into the standard care pathway for stress echocardiology.
The INTERCLIMA (Interventional Strategy for Non-culprit Lesions With Major Vulnerability Criteria Identified by Optical Coherence Tomography in Patients With Acute Coronary Syndrome) is a multi-center, prospective, randomized trial of optical coherence tomography (OCT)-based versus physiology-based (i.e. fractional flow reserve[FFR]/instantaneous Wave-Free Ratio[iFR]/resting full-cycle ratio[RFR]) treatment of intermediate (40-70% diameter stenosis at quantitative coronary angiography), non-culprit coronary lesions in acute coronary syndrome (ACS) patients undergoing coronary angiography. About 1400 patients with ACS will be randomized into the study at approximately 40 sites worldwide.
