Effect of Dapagliflozin on Microvascular Function in Women With Symptoms of Coronary Artery Disease...

Myocardial Ischemia

The goal of this clinical trial is to test the effects of a drug (in the drug class called sodium-glucose cotransporter 2 inhibitors) in women who have symptoms of ischemic heart disease. The main questions the study aims to answer are: Does blood flow in the heart improve with study drug? Participants will be randomly assigned to a 12-week course of the study drug, dapagliflozin 10mg, or placebo. Blood flow in the heart will be assessed using stress cardiac magnetic resonance imaging at baseline and 12 weeks. The researchers will compare the results from the two groups.

HIIT vs HRV-based Training for Rehabilitation After Stroke

StrokeCardiac Disease4 more

Consequences of stroke are manyfold but all of them are important factors on the long-term outcomes of rehabilitation, becoming an important health problem with requires health strategies with advanced age. High intensity interval training (HIIT) is an efficient training protocol used in cardiac rehabilitation programs, but owing to the inter-individual variability in physiological responses to training associated to cardiovascular diseases, the exercise dose received by each patient should be closely controlled and individualized to ensure the safety and efficiency of the exercise program. The heart rate variability (HRV) is actually being used for this purpose, as it is closely linked to de parasympathetic nervous system activation. In this way, higher scores in HRV are associated with a good cardiovascular adaptation. The objective of this protocol is to determine the effect of HIIT compared with HRV-guided training on cardiorespiratory fitness, heart rate variability, functional parameters, body composition, quality of life, inflammatory markers, cognitive function, and feasibility, safety and adherence in patients after stroke undertaking an 8-week cardiac rehabilitation program. This will be a cluster-randomized controlled protocol in which patients after stroke will be assigned to an HRV-based training group (HRV-G) or a HIIT-based training group (HIIT-G). HIIT-G will train according to a predefined training program. HRV-G training will depend on the patients' daily HRV. The peak oxygen uptake (VO2peak), endothelial and work parameters, the heart rate variability, the functional parameters, the relative weight and body fat distribution, the quality of life, the inflammatory markers, the cognitive function, and the exercise adherence, feasibility and safety will be considered as the outcomes. It is expected that this HRV-guided training protocol will improve functional performance in the patients after stroke, being more safe, feasible and generating more adherence than HIIT, providing a better strategy to optimize the cardiac rehabilitation interventions.

Polypill in Acute Coronary Syndrome

Acute Coronary SyndromeLipid Disorder1 more

Acute coronary syndromes (ACS) represent a major contributor to mortality, morbidity, and healthcare costs. Effective therapies are widely available; however, adherence is low. This contributes to worse patient outcomes and increased risk of morbidity and mortality. The once-daily polypill leverages a population-based strategy that has previously demonstrated efficacy in improving adherence and access to therapy in low-resource settings, making it an innovative approach for improving post-ACS care. This study aims to investigate the utility of a polypill-based strategy for patients with ACS with drug eluting stent (DES) placement. The polypill will consist of a high-intensity statin (rosuvastatin 40 mg daily), aspirin 81 mg daily, and either clopidogrel 75 mg or prasugrel 10 mg daily.

Electroacupuncture for Heart Protection: Clinical Application in Patients Undergoing Cardiac Bypass...

Coronary Artery DiseaseElectro-Acupuncture

Coronary artery disease (CAD) is the leading cause of death and disability in Singapore and worldwide. Many patients with multi-vessel CAD require surgical revascularisation by coronary artery bypass graft (CABG) surgery, and are at risk of postsurgical complications such as peri-operative myocardial injury (PMI), left ventricular dysfunction, heart failure, and death. This risk is particularly important given that the aging population, and increased prevalence of co-morbidities (diabetes, hypertension, renal failure) and complexity of cardiac surgery, mean that higher risk patients are undergoing CABG surgery. As such, new treatment strategies are required to protect the heart during CABG surgery in order to improve health outcomes in patients with CAD. In this regard, a number of animal studies have demonstrated that electroacupuncture (EA) at cardiac-related acupoints can protect the heart against the detrimental effects of acute ischaemia/reperfusion injury (IRI). However, the mechanisms underlying the beneficial effect of EA, and whether EA can protect the heart against PMI in patients undergoing CABG surgery are not known. Therefore, in this research proposal, the investigators will investigate whether EA at cardiac-related acupoints can protect the heart against PMI during CABG surgery, and the investigators will elucidate the mechanisms underlying the cardioprotective effects of EA.

HuoXin Pills Intervention on Patients With Coronary Heart Disease After Drug-Coated Balloon Implantation...

Coronary Heart DiseaseMedicine1 more

This trial is a multi-center, randomized, double-blind, placebo, parallel controlled study. Objectively evaluates the curative effect of Huoxin Pills (concentrated pills) intervention on improving the prognosis of patients with coronary heart disease after drug-coated balloon implantation from a functional point of view. Huoxin Pill(concentrated pills), a traditional Chinese medicine, has been prescribed widely in the treatment of coronary heart disease, angina pectoris, and other diseases.440 patients were selected and followed up for one year. The quantitative blood flow score of the target vessel, late lumen loss, MACE incidence, and safety index were observed at 12 months.

Coronary Artery DiseaseCoronary Artery Bypass Grafting5 more

Ticagrelor-based De-escalation of Dual Antiplatelet Therapy After Coronary Artery Bypass Grafting trial (TOP-CABG trial) is a multicenter, randomized, double-blind, non-inferiority, parallel controlled trial. The aim of TOP-CABG is to investigate whether de-escalated dual antiplatelet therapy (De-DAPT) is non-inferior to dual antiplatelet therapy (DAPT) in efficacy on inhibiting great saphenous vein (SVG) graft occlusion and is superior in reducing bleeding events in patients accepting coronary artery bypassing grafting.

Ischemic Heart Disease

Previous randomized clinical trials have deomonstrated the efficacy and safety of short-term dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI), however, the single antiplatelet agent to be maintained after short-term DAPT was different. Therefore, which antiplatelet agent to be maintained after short-term DAPT needs further invstigations.

Although recommended therapy for patients with ST-segment elevation myocardial infarction is primary PCI, it remains unestablished whether patients with a symptom duration of more 12 hours benefit from acute revascularisation. This study aims to investigate whether acute intervention is superior to subacute intervention in these patients.
