This is a single-center double blind, placebo controlled study of patients undergoing a cardiac catheterization where the need for a percutaneous coronary intervention (PCI) is anticipated or will be determined during the early diagnostic phase. The study will assess the use of intracoronary nicardipine vs. sterile saline injection in reducing the index measurement of microcirculatory resistance (IMR). Fifty consecutive patients presenting to the Thomas Jefferson University (TJ...
Among patients with stable ischemic heart disease who are referred for coronary angiography, a substantial proportion have non-obstructive coronary artery disease (CAD). Ischemia based on symptoms or stress testing may be due to coronary microvascular dysfunction in up to 40% of these patients. However, the mechanisms and optimal treatment of coronary microvascular dysfunction are unknown. Aberrant platelet activity and inflammation have been hypothesized as mechanisms of micro...
This clinical trial will explore the safety and effect of GCSF-mobilized autologous ex vivo selected CD34 cells for the treatment of CMD in adults currently experiencing angina and with no obstructive coronary artery disease. Eligible subjects will receive a single intracoronary infusion of CLBS14.
Effect of Complementary Intracoronary Streptokinase Administration Immediately After Primary Percutaneous Coronary Intervention on Microvascular Perfusion and Late Term Infarct Size in Patients With Acute Myocardial Infarction
The investigators hypothesized that complementary intracoronary streptokinase administration to primary percutaneous intervention in patients with acute myocardial infarction may provide further improvement in myocardial perfusion by dissolving microvascular thrombus [in situ formed or embolized from proximal site (spontaneous or following PCI)] and fibrin.
The aim of the present study is to evaluate the effect of treatment with Liraglutide on the coronary microvasculature and angina symptoms, in overweight patients with microvascular dysfunction and angina pectoris but no coronary artery stenosis.
The aim of the study is to test whether, in patients with angina and flow limiting epicardial coronary artery disease, pre-treatment with Ivabradine, as opposed to beta blockers, will reduce post percutaneous coronary intervention induced microvascular dysfunction.
Angina is the most common symptom of coronary heart disease among women but unlike men most women do not have stenosis of the coronary arteries. In a large proportion of these women, coronary microvascular dysfunction (CMD) is thought to be the cause of angina. However, CMD is also demonstrable in the asymptomatic population, and may merely be an innocent bystander related to the presence of cardiovascular risk factors rather than a cause of angina symptoms. The aim of t...
How safe and effective are CD34+ cell intracoronary injections for treating coronary endothelial dysfunction (CED)?
Background: Percutaneous coronary intervention (PCI) for acute coronary syndromes frequently fails to restore myocardial perfusion despite establishing epicardial vessel patency. Endothelin-1 (ET-1) is a potent vasoconstrictor and its expression is increased in atherosclerotic coronary arteries. Our hypothesis is that increased activity of the endogenous endothelin system contributes to microvascular dysfunction, and adjunctive therapy with an endothelin receptor antagonist wi...
Coronary Artery Disease (CAD) is common in Mexico, while morbidity and mortality is high. Drug therapy can relieve angina pain and stabilize plaque, but it is not able to re-flow a coronary artery. Balloon angioplasty and/or stent placement, re-establishes coronary blood flow; however, the risk of re-stenosis and/or development of new coronary events remains latent. Endothelial damage, reflected by the degree of endothelial dysfunction, inflammation and oxidative stress, promot...
Abnormal coronary microvascular vasodilation has been demonstrated in patients with diabetes and metabolic syndrome, but the role of insulin resistance in its pathogenesis is not clear. The aim of this study is to invasively assess coronary microcirculation and to investigate the relationship of insulin resistance with coronary microvascular dysfunction. A pressure temperature-sensor-tipped coronary wire will be advanced in coronary arteries without significant lumen reduction...
Goal of the registry is to collect data on patients undergoing coronary angiography in Mainz. Following amendment of the procol, this study will also include patients who received an Aborb bioresorbable scaffold for the therapy of de novo stenoses.
This is a prospective study which aims to explore the effect of Trimetazidine on the improvement of coronary microvascular dysfunction in patients with INOCA (ischemia and no obstructive coronary artery disease). Enrolled patients will be assessed SAQ(Seattle Angina Score), Canadian Angina Grade(Canadian Cardiovascular Society, CCS), Six-Minute Walk Test, CFR(coronary flow reserve) .CFR inspection with D-SPECT and pressure guide wire.Patients will receive six months Trimetazidi...
The aim of this study was to compare the efficacy of nicardipine and labetalol in attenuation of cardiovascular responses to endotracheal intubation.
After PCI searching for target lesion ischemia with intracoronary ECG will be performed and if found it will be treated pharmacologically
Objective The objective of this study is to discover whether an infusion of nicardipine is able to reduce the time taken to achieve electrocerebral silence (ECS) during cardiopulmonary bypass (CPB) for aortic surgery. Hypothesis By inhibiting cold-induced cerebral vasoconstriction, nicardipine will maintain cerebral blood flow and allow more rapid cooling of the brain during CPB. This will manifest as a reduction in the time taken to achieve ECS and also as a red...
The aim of this study is to explore effects of long term treatment with ACE-inhibitor on the small vessel function assessed by coronary flow reserve (CFR) by transthoracic echocardiography and flow mediated dilation in normotensive patients with small vessel disease (CFR
This study is undertaken to determine if intravenous Lipo-PGE1 therapy would improve coronary microvascular perfusion in patients with ischemic heart disease by CMRI.
The purpose of this study is to evaluate the prognosis of coronary stenosis based on intracoronary Imaging.
The aim of this randomized trial is to compare the efficacy of high dose tirofiban administered as either an intracoronary bolus alone or as an intravenous bolus followed by a maintenance infusion with respect to microvascular perfusion and long term left ventricular infarct size, volumes and function.
Aim of the study is to evaluate the benefits from adjunctive intracoronary administration of adenosin in elective patients undergoing coronary angioplasty.
Long-term prognostic value of macrovascular and microvascular coronary artery stenoses in each type of cardiomyopathy.
The aim of this study is to confirm that URAPIDIL is as efficient and as safe as NICARDIPINE to correct severe hypertension in pre-eclamptic patients. - efficacy endpoint : mean arterial blood pressure corrected to 105-125 mmHg after 120 min of study drug administration. - safety endpoints : clinical, biological and ultrasound observation for any side effect.All infants will be observed in the neonatology unit (during 48h).
This will be a prospective, phase IIIb, double-blind and randomized trial testing the effect of single dose sildenafil application in patients with coronary vasospasm compared to placebo application. The target variable to be tested is the degree of coronary vasoconstriction in response to intracoronary ACh application (in addition to clinical chest pain) which will be imaged by coronary angiography and measured using quantitative coronary angiography software. Main obj...
The aim of this study is to evaluate if the intracoronary infusion of autologous bone-marrow derived CD133+ endothelial precursor cells is able to promote neovascularization and to improve myocardial perfusion and contractility in patients with refractory coronary heart disease, characterized by poor response to standard coronary interventions, severe impairment of the quality of life, and poor prognosis.
