Filter by:A multi-center, prospective, observational, non-interventional single arm, study of the intermediate-term clinical outcomes collected from electronic health records of high-risk patients which have previously undergone standard of care prophylactic Impella support for a non-emergent percutaneous coronary intervention (PCI).
The objective of this study is a comparative evaluation of Orsiro stent and of Resolute Integrity stent in terms of the extent of neointima formation at 4 months after implantation using optical coherence tomography (OCT).
The principal objective of this research is to determine whether symptoms, induced by confirmed experimental ischaemia, can help us predict which patients will respond to PCI.
The purpose of this implementation trial is to execute a nurse-led, home-based cardiac rehabilitation (HBCR) program, evaluate the program's impact on patient outcomes over 6 months; and compare outcomes of HeartHome (HH) participants to a group of participants in traditional cardiac rehabilitation (CR).
The Distal Radial Access (DRA) to the coronaries has emerged recently. It's done via the distal radial artery in the radial fossa, which is known as the snuff-box. The rationale of conducting this research is to assess this new access advantages and disadvantages, in comparison with the standard conventional forearm radial access and examine if it's worthy to be a future alternative method for coronary angiography. It aims to randomly compare between the new distal radial access via the snuffbox and the conventional forearm radial access for percutaneous coronary angiography and angioplasty procedures. The objectives of comparing both procedures are to analyze the frequency of complications in terms of occlusion, arterial spasm, hematoma, and to weigh accesses effectiveness in terms of time and attempts to puncture, crossover rate, procedure duration, hemostasis time, and convenience of the patients and operators. Candidates for coronary angiography are being randomized into the interventional group to undergo the angiography through the distal radial artery as the access site, or the control group accessing through the radial artery in the forearm. Procedural and post procedural outcomes and complications are being reported while patients are in hospital. All patients undergo doppler ultrasonography within 24 hours after the procedure.
This study evaluates the addition of the CADScorSystem to a standard Diamond-Forrester score guided rule-out strategy in ambulatory patients referred with symptoms suggestive of stable coronary artery disease. Half of the patients will undergo stratification using a Diamond-Forrester score only, while the other half will undergo stratification using a Diamond-Forrester score and a CAD-score. The study hypothesis is that the addition of a CAD-score will reduce unnecessary testing without compromising patient safety.
Patients aged 18-89 with stable CAD and comorbidities receiving optimal medical treatment requiring PCI with iodinated contrast media. The aim of the study is to assess the prevalence of contrast-induced AKI in 2012-2013 and 2017 cohorts and to evaluate the potential risk factors of CI-AKI to better guide the prevention in patients of higher risk.
In patients with chronic stable coronary artery disease (CAD), percutaneous coronary intervention (PCI) targets hemodynamically significant coronary lesions, i.e., those thought to cause inducible ischemia. The hemodynamic severity of a coronary stenosis increases with its tightness and with the myocardial mass of viable myocardium downstream of the stenosis. Compared to the traditional anatomic angiographic approach, assessment of functional relevance by fractional flow reserve (FFR) during coronary angiography has been suggested to improve patient outcomes. Fractional flow reserve (FFR) is based on determination of the coronary perfusion pressure downstream of a stenosis during pharmacologic hyperemia. However, FFR relies on oversimplified physiologic concepts, which limits its usefulness in defining a true ischemic threshold. Furthermore, visual angiographic assessment continues to dominate the treatment decisions for intermediate coronary lesions. Conversely, the intracoronary ECG (icECG) provides an inexpensive, sensitive and direct measure of myocardial ischemia. The icECG is easily acquired by attaching a reusable alligator clamp to a conventional angioplasty guidewire (at one tenth the price of a pressure sensor guidewire). The coronary guide wire positioned downstream of a coronary stenosis then acts as the exploring electrode. During pharmacologic stress, the icECG can provide direct evidence for regional myocardial ischemia to define the ischemic threshold in different types of coronary artery disease.
This study, taking stable angina pectoris as a research carrier, aims to explore the preventive value of acupoint sensitization by conducting a double-blind multi-center randomized controlled trial to compare the effect of stimulating acupoints with different sensitivity on the prevention of angina pectoris. After the inclusion of eligible patients, the pressure-pain threshold of disease-related acupoints will be detected by using Von Frey detector. Then, the patients will be randomly divided into experimental group and control group. The patients in experimental group will be given acupoints pressure on the five acupoints with the lowest pressure-pain threshold, while the patients in control group will be given acupoints pressure on the five acupoints with the five acupoints with the highest pressure-pain threshold. The two groups will be treated with acupoints pressure 12 times within 4 weeks. The patients will be evaluated three times at baseline, the end of treatment and four weeks after the end of treatment respectively, including angina attack frequency, CCS classification and SAQ score.
early identification of vulnerable plaques by remodeling index prior to rupture and development of acute event is of considerable importance especially by a reliable non-invasive method as CT coronary angiography.
