53 Clinical Trials for Various Conditions
This is a multi-center, double-blind, randomized, placebo-controlled, parallel-group phase 3 clinical study to confirm the safety and efficacy of T89 in patients with stable angina pectoris, with an extended open-label period to evaluate the long-term safety of T89. This study includes three main periods: the first study period is a 3-week single-blind qualifying run-in period to screen eligible stable angina patients by exercise tolerance test (ETT). The second study period is a 8-week double-blind treatment period to evaluate the efficacy and safety of T89 in patients with stable angina by ETT. And, the last study period is a 44-week open-label period to observe long-term use safety of T89.
This phase III study is designed as a double blind, randomized, multi-nation, multi-center, placebo controlled clinical research, which aims to evaluate the safety and efficacy of Dantonic® (T89) in patients with chronic stable angina pectoris.
This study will evaluate the effect of ranolazine compared to placebo on the average weekly angina frequency in subjects with chronic stable angina and coronary artery disease (CAD) who have a history of type 2 diabetes mellitus (T2DM), and whether ranolazine can reduce the frequency of angina (chest pain) attacks, compared to a placebo. Subjects will be asked to record their daily angina episodes in a diary at the end of each study day. Ranolazine is approved for the treatment of chronic angina, and is not approved for the treatment of T2DM.
This randomized, controlled, diagnostic, multicenter trial will compare two diagnostic imaging pathways--coronary computed tomography angiography (CCTA) and single photon emission tomography (SPECT) myocardial perfusion imaging (MPI)--to determine the incidence of major adverse coronary events (MACE), defined as myocardial infarction (MI) or cardiac-related death, and cross-over to revascularization. CCTA may be used to direct patients with symptoms of stable angina or angina equivalent to optimal medical therapy (OMT). The use of CCTA as a diagnostic tool for angina symptoms will be associated with no increase in MACE or revascularization, decreased cost, reduced risks (e.g., less radiation exposure), additional insights into alternate explanations of chest pain, and increased cost-effectiveness in comparison with use of SPECT MPI/invasive coronary angiography (ICA).
The purpose of this study is to determine the anti-angina effect and dose response of T89, a 2-herb botanical drug product, in patients with chronic stable angina pectoris in the United States.
The goal of this clinical trial is to determine if a standardized 12-point acupuncture protocol will reduce pain in participants with stable angina. This study addresses the critical need to reduce persistent pain for angina. The investigators long-term goal is symptom management for diverse women and men with angina, targeting additional angina burden borne of social disadvantage Participants will be randomized to a 10-acupuncture session protocol, two treatments per week for five weeks, or an attention control group. Participants will view designated, non-pain related Technology, Entertainment, Design Talks equal to the time spent receiving acupuncture (\~7.5-10 hrs.). The investigators will test the efficacy of acupuncture for stable angina/chest pain syndrome to reduce pain and symptoms, improve health-related quality of life, reduce healthcare utilization and and improve patient related health outcomes.
To establish the effectiveness and tolerability of standard of care anti-anginal treatment (beta-blocker and calcium channel blocker medications) in older adults with symptomatic Stable Ischemic Heart Disease (SIHD) and multiple chronic conditions (MCC).
Primary Objective: To assess the effects of SAR407899 on coronary vasomotor function using the coronary flow reserve (CFR) in participants with microvascular angina (MVA) and/or persistent stable angina despite angiographically successful percutaneous coronary intervention (PCI). Secondary Objectives: * To assess the effects of SAR407899 on quality of life using Seattle Angina Questionnaire physical limitation scale (SAQ-PL) in participants with MVA and/or persistent stable angina despite angiographically successful PCI. * To assess the safety of SAR407899 in participants with MVA and/or persistent stable angina despite angiographically successful PCI with a focus on identified risks such as hypotension and orthostatic hypotension. * To assess SAR407899 plasma concentrations in MVA participants and/or persistent stable angina despite angiographically successful PCI.
This RCT aims to determine if it is possible to perform acupuncture on men and women diagnosed with stable angina who have symptoms, chest pain, and/or chest discomfort. The investigators want to determine if acupuncture reduces the pain and other symptoms of angina, chest pain, and chest discomfort. The investigators also want to examine whether this study is acceptable to the participants, and by carrying out this study the investigators will be able to tell how many participants they will need in a future larger study to further test acupuncture to reduce the symptoms of angina in women.
This is a prospective, double-blind, placebo-controlled, randomized, single-center (North Florida- South Georgia VA Medical Center) study. The study objective is to determine if ranolazine improves angina symptoms at 4 months compared with placebo among stable coronary artery disease patients who have demonstrable myocardial ischemia, but who do not undergo revascularization
Ticagrelor therapy has been shown to reduce the rates of cardiovascular events and all-cause mortality compared to clopidogrel therapy in patients with acute coronary syndromes (ACS). The benefit of this study would be to demonstrate that ticagrelor therapy is associated with equivalent platelet inhibition irrespective of the disease status in patients undergoing PCI.
The purpose of this study is to assess the effect of febuxostat on coronary artery flow in patients with coronary artery disease.
The purpose of this study is to evaluate the effect of febuxostat, once daily (QD), compared to placebo as an add on to stable anti-anginal therapy, on the total exercise time of participants with Chronic Stable Angina.
The purpose of this study is to test the hypothesis that application of topical capsaicin in patients with stable angina will result in improved exercise tolerance and reduced cardiac ischemia.
The purpose of this study is to evaluate the safety and tolerability of catheter based injections of VM202 into the heart.
The primary objective of the study is to evaluate the difference in 6-month restenosis rates in coronary artery lesions treated by photopheresis in addition to angioplasty with stent placement, as opposed to no photopheresis after angioplasty and stent placement. Restenosis means the closing up again, or narrowing in diameter, of the previously treated artery, which may cause reduced blood flow and the re-occurrence of symptoms. Photopheresis is a therapeutic technique in which a portion of your white blood cells is collected by a blood separation device and exposed to ultraviolet A light, in combination with the drug 8-MOP (8-methoxypsoralen), then returned to you. The secondary objectives are: 1. To compare the incidence of major adverse cardiac events (MACE) between the three treatment groups for 6 months post-angioplasty. MACE events include death (cardiac related), myocardial infarction, coronary artery bypass graft surgery, repeat angioplasty to the target vessel, hospitalization and clinical symptoms. 2. To evaluate the safety of the treatment by comparing the incidence of acute and subacute thrombosis, bleeding and vascular complications and other non-MACE events every 2 weeks for 6 months post-angioplasty between the three treatment groups.
The goal of this clinical trial is to find out whether fasting is necessary before urgent inpatient cardiac catheterizations. For patients presenting with urgent heart-related pain or even mild heart attacks, researchers want to know whether eating and drinking before their procedure improves comfort without raising the risk of complications. The study will answer: * Does eating and drinking before the procedure improve patient comfort? * Does it increase the risk of adverse events like vomiting, aspiration (food or liquid entering the lungs), breathing problems, or death, etc? Participants will be randomly assigned to either: * A standard fasting group (no food for 6 hours, no clear liquids for 2 hours), or * A no-fasting group (able to eat and drink as usual). Patients will complete brief surveys before the procedure to assess comfort and satisfaction. Researchers will also review medical records weekly and 30 days later to monitor for safety outcomes.
This retrospective study will evaluate the coronary angiograms of approximately 100 patients who have undergone invasive angiography and fractional flow reserve (FFR). DICOM files of the angiograms will be analyzed on a secure computer within the cardiac catheterization laboratory using the AutocathFFR software to assess if invasive FFR measurements and automated computer analysis of FFR measurements correlate. AutocathFFR measurement per lesion will be compared to the gold standard, invasive FFR value, where an FFR ≤ 0.80 will be considered "positive", while an FFR \> 0.8 will be considered "negative". The AutocathFFR value will be compared to the invasive FFR measurements. The sensitivity and specificity of the AutocathFFR will be calculated, as well as the AutocathFFR accuracy, positive predictive value and negative predictive value per lesion. Device success will be calculated as the ratio of completed versus initiated AutocathFFR index calculations. Usability of the AutocathFFR software will be evaluated using dedicated questionnaires to be completed by the user (cardiologists).
A phase 2a, multicenter, randomized, double-blind, placebo-controlled study in adults with stable angina to evaluate the effect of erenumab (AMG 334) compared to placebo on exercise time during an exercise treadmill test.
The purpose of this study is to determine the effects of ranolazine on different markers of cardiometabolic disease in women with stable angina.
The primary objective is to assess whether the increased angina threshold on ranolazine and subsequent higher training intensity will result in improved exercise tolerance and oxygen consumption; and greater than that observed with exercise training on placebo. The study team anticipates the chronic exercise improvements with ranolazine will be incrementally higher than the acute effects provided by ranolazine alone and demonstrated in previous trials. Key secondary objectives include the acute ranolazine and chronic exercise plus ranolazine effects on total daily energy expenditure (TDEE) and angina-related quality of life.
Despite several large clinical trials clearly establishing that coronary revascularization (i.e. percutaneous coronary intervention - PCI) does not prolong survival or prevent myocardial infarction (MI) for stable coronary artery disease (CAD), patients with stable angina continue to believe that PCI is performed to improve these outcomes. Additionally, recent concerns have emerged of overuse of PCI among patients with little or no angina. Thus there is a compelling need to share with patients the risks and benefits of PCI prior to treatment to reach an informed decision. This study is designed to answer the question of whether a decision aid can improve patient knowledge, decisional conflict and patient satisfaction with decision-making compared to usual care for the treatment of stable angina.
Ranolazine is an effective and remarkably safe agent for the treatment of patients with chronic stable angina, but its inhibition of voltage gated potassium channels and electrocardiogram (EKG) corrected QT (QTc) prolongation properties have lead many to question its safety when combined with antiarrhythmic drugs. The investigators have proposed a study to determine the safety of ranolazine in patients with chronic stable angina who also take amiodarone. And are conducting a prospective single-center randomized single-blinded placebo controlled trial to run out of our large cardiology practice setting at Cardiovascular Consultants of Nevada. The hypothesis is that there will be no difference in the ventricular arrhythmia burden. The primary outcome will be the measurement of ventricular arrhythmia episodes on serial holter monitor and other serially acquired recordings (such as electrocardiogram, pacemaker or implantable defibrillator (ICD) data, and stress test data) over a three month trial period.
Purpose: This study is to determine the effect of T89(Dantonic®)on P450 enzymes. This study will help determine which types of drugs may interact with T89.
The objective of this study is to evaluate if aggressive antiplatelet therapy would reduce ischemic events in aspirin (ASA) resistant patients after percutaneous coronary intervention (PCI).
The purpose of this research is to find out if doing cardiac rehab at home, or a mix of cardiac rehab at home and in the clinic, is as effective as coming in to the clinic for cardiac rehab.
The aim of this study is to evaluate feasibility, efficacy, and adherence of home-based cardiac rehabilitation with the integration of telemedicine. Several components will be assessed such as quality-of-life, nutritional counseling, maximum metabolic activity (MET's), diabetic management, tobacco cessation, lipid, blood pressure, and psychosocial management. These tasks will be accomplished through concurrent conversations between patients and their therapist's utilizing telemedicine with observed exercise training.
Adherence to cardiac rehabilitation is poor, and worse for minorities, women, and those with lower levels of education. Patients less likely to be referred to and complete cardiac rehab are at highest risk of adverse outcomes and thus have the most to gain from participation in cardiac rehab. To improve participation, healthcare systems need to limit barriers to enrollment and promote adherence to rehabilitation.
Cardiac rehabilitation (CR) is strongly recommended for patients with coronary heart disease. However, patient enrollment and completion of cardiac rehabilitation is low. This study will examine if a mobile phone intervention that uses a text messaging program can successfully promote participation in cardiac rehabilitation.
The guideline-recommended standard of care for patients who have experienced a heart attack, heart failure, or other coronary event or procedure is exercise-based cardiac rehabilitation (CR). Despite proven benefits, traditional CR is severely underutilized. Moreover, what is typically lacking from traditional CR programs is effective psychosocial risk management. This represents a critical gap in care given the well-documented psychosocial needs of this patient population.The objective of this feasibility study is to conduct a pilot randomized controlled trial (RCT) of Mindfulness-Based Stress Reduction (MBSR) versus usual care in CR-eligible cardiac patients. Randomization will be stratified within two strata based on participation in CR (yes/no) among CR-eligible patients. The primary goals of this pilot study are to: 1) obtain estimates of treatment effects and variability; 2) evaluate recruitment and retention strategies; and 3) examine the safety of the MBSR protocol in CR-eligible patients.
