Filter by:NSTE-ACS represents the most frequent indication for coronary angiography and percutaneous coronary intervention (PCI) worldwide. PCI permit to reestablished coronary flow but effectiveness of PCI within thrombus containing lesions is limited by the risk of occurrence of distal embolization and no-reflow phenomenon. Distal embolization lead to coronary microcirculation lesions. This complication is related to poor prognosis. MGuard stent is a stainless-steel closed cell stent covered with an ultra-thin polymer mesh sleeve, which allows to prevent distal embolization during percutaneous coronary intervention in ST-segment-elevation myocardial infarction. Index of microcirculatory resistance (IMR) is a validated method to assess coronary microcirculation. Accordingly, the purpose of this study is to demonstrate that MGuard micronet mesh-covered stent prevent distal embolization and microvascular reperfusion impairment during primary PCI, compared with a bare metal stent (BMS) and drug eluting stent (DES) in patients with NSTE-ACS, assessed by Index of microcirculatory resistance.
Evaluation of coronary artery vessel wall healing at different time points in patients undergoing implantion of bioresorbable vascular scaffold by using intravascular imaging. In addition long-term clinical follow-ups are planned for all patients treated with Absorb in the institution
This pilot randomized control trial will examine the role of choral singing on psychosocial stress and cardiovascular outcomes in patients with ischemic heart disease (IHD). The hypothesis is that choral singing will improve psychosocial stress in comparison to the control group and this may have an impact on rates of hospitalization, death, myocardial infarction and stroke in these patients.
Angina and heart attacks are caused by narrowings in the coronary arteries (blood vessels) supplying the heart. These narrowings can be opened using a balloon and stent (angioplasty). Traditionally, stents are constructed from metal and are permanent. However, newer stents are being constructed from carbohydrate polymers (scaffolds), which allow them to reabsorb over time leaving no permanent implant. New data has suggested that these scaffolds appear to reduce recurrent angina and may alter the blood flow down the artery. However, it is not known whether this is due to the scaffolds themselves or the way the scaffolds are inserted. In this study we hope to measure the blood flow to the heart and assess changes in that flow during stent and scaffold insertion. It is also important to know whether these effects are durable and thus, a cohort of patients will return at 3-months to be restudied. These data are important to help us understand why blood flow is affected by stent/scaffold selection or device implantation technique and whether this results in better long-term outcomes.
The objective of this study is to investigate the value of employing the aortic no-touch off-pump coronary artery bypass technique and the practice of carbon dioxide surgical field flooding for the prevention of type 1 and 2 neurological injuries following surgical coronary revascularization.
It is widely accepted that coronary artery disease (CAD) is related to a high mortality. It is predicted that an increase of approximately 21.3 million cardiovascular events and 7.7 million cardiovascular deaths over 2010 to 2030 in China.1 Male sex, diabetes mellitus, hypertension, hypercholesterolemia, obesity and smoking are all traditionally considered as risk factors for CAD. In recent decades, tremendous progress toward the prevention and treatment of traditional cardiovascular risk factors have helped decrease the morbidity and mortality from CAD, but the condition remains a major public health challenge worldwide. Looking into the other potential risk factors (OSA) for CAD, it may help to develop additional preventative strategies and further reduce the incidence and mortality of CAD.
ORBID-OA is a single-center, observational study in 30 patients with stable coronary artery disease. The aim of the study is to analyze the outcomes of main vessel stenting on side branch in calcified bifurcation lesion and identify preprocedural predictors of side branch complication by utilizing two-dimensional (2D) and three-dimensional (3D) frequency domain optical coherence tomography (FD-OCT).
This was a prospective randomized, controlled trial designed to quantify the reduction in cost and length of stay of early discharge of emergency department patients evaluated for acute myocardial infarction, who are deemed to be low risk based on a modified HEART score (a score that incorporates troponin biomarker, ecg, patient characteristics, and physician clinical judgment).
The aim of this study was to determine the diagnostic accuracy of SURECardio CT-FFR to detect functionally significant coronary stenosis.
Coronary heart disease (CHD) is a public health care challenge. There are three types of treatment for CHD, medication, percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG). However, some end-stage CHD patients lost the chance to get those treatment. Cardiac shock wave therapy (CSWT) is a new developed therapy for these patients, which is used in tens of countries all over the world. Safety, invasiveness, effectiveness is its advantage. Ischemia condition can be improved after CSWT. There are only three cities in China run the program of CSWT, which are Kunming, Beijing and Shanghai. The investigators designed a randomized double-blind study to evaluate the effectiveness and safety of CSWT.
