Filter by:Despite advances in the treatment of heart attacks the complications and death rates from failure of the heart to pump properly after treatment remain high. A heart attack occurs when one or more of the arteries that supply blood to the heart become blocked, causing the heart to be starved of oxygen and nutrients. This results in damage to the heart and so the the heart pumps less well. The main treatment for a heart attack is balloon treatment to open the blocked artery (called primary angioplasty). Whilst re-opening the artery is essential and allows blood to flow to the area of the heart starved of oxygen, this process also causes damage itself (called reperfusion injury) and increases the size of the heart attack further. Currently there are no treatments available that reduce this reperfusion injury. The investigators and others have shown that a substance called sodium nitrite reduces reperfusion injury in experimental models of a heart attack. The aim of this research is to perform a trial to investigate whether during a heart attack, an infusion of sodium nitrite into the damaged artery protects against reperfusion injury and reduces heart attack size in patients.
The registry aims to evaluate the safety, performance and efficacy of the Everolimus-eluting bioresorbable vascular scaffold (BVS) system in patients with de novo native coronary artery lesions in all-day clinical practice.
The purpose of this study is to assess the non-invasive, Peripheral Arterial Tonometry (PAT) testing as another way of predicting potential coronary artery blockages in the heart.
The investigators' hypothesis is that local activation of the endogenous Lipoprotein-associated phospholipase A2 (Lp-PLA2) plays an integral role in early atherosclerosis, and contributes to the mechanism of coronary endothelial dysfunction and to the structural and mechanical properties that characterize plaque vulnerability. Thus, this study will characterize prospectively the correlation between the functional and structural vascular wall properties, and the activity of the Lp-PLA2 pathway.
This randomized, placebo-controlled, double-blinded trial investigates the effect of a 6 week intake of PADMA 28 on the endothelial function, biomarkers and the autonomic nervous systems in patients with coronary artery disease. The investigators hypothesize that PADMA 28 has a beneficial effect on endothelial function, arterial stiffness, the autonomic nervous systen and the blood inflammatory markers in patients with coronary artery disease compared to placebo treatment.
The purpose of this study is to determine the effectiveness of cardiac shock wave therapy (CSWT) for the treatment of severe coronary artery disease (CAD) in a Chinese cohort.
The aim of this study is to prospectively investigate the relationship of circulating endothelial progenitor cells at time of percutaneous coronary intervention to the subsequent development of in-stent restenosis or progression of coronary atherosclerosis.
Objectives: The investigators examined whether rosiglitazone, a thiazolidinedione (TZD), is beneficial for pre-diabetes mellitus (DM) adults with documented coronary artery disease (CAD). Background: Microvascular and macrovascular complications are common in type 2 DM. There is no evidence about the effects of TZDs, synthetic peroxisome proliferator-activated receptor (PPAR)-γ activators (insulin sensitizers and adipose transcriptional regulation and anti-inflammatory process activators) on pre-DM patients with documented CAD.
The investigators hypothesize that in a real-world population undergoing percutaneous coronary intervention (PCI) for de-novo stenoses in small native vessels with a diameter <3 mm, drug eluting balloons (DEB) are non inferior to third-generation drug eluting stents (DES).
Blood is anticoagulated using a drug named heparin during open-heart surgery to allow it to safely pass through the heart-lung machine which pumps the blood throughout the body during the surgery. Each patient is given the heparin they need for their surgery. This means some patients receive more or less heparin than other patients. In this study, the investigators will be evaluating the current anticoagulation protocol for open heart surgery in use at the Royal University Hospital. The goal of this project is to compare patients who require and receive more heparin for proper anticoagulation to those patients who require and receive less heparin. Open-heart surgery will proceed according to the standard hospital protocol. All research participants will be treated according to standard post-open heart surgery protocol in the ICU. This will include measurement of blood loss by keeping track of chest tube outputs and administration of blood transfusions. This study focuses on Saskatoon Health Region patients having open heart surgery in terms of the protocol for anticoagulation and blood transfusions.
