Filter by:A retrospective cohort study was performed in patients with angina pectoris who were treated with oral Chinese patent medicine and Western medicine.The hospital's medical record management system was used to collect symptoms of angina pectoris, dose and frequency of nitroglycerin use, clinical biochemical test and imaging examination.To explore the clinical efficacy of Chinese patent medicine in the treatment of coronary heart disease with angina pectoris, and provide reliable data support for its clinical application.
With the upcoming expansion of transcatheter aortic valve replacement (TAVR) indications to younger patients, the feasibility of coronary ostia cannulation beyond different bioprosthesis stent is currently a matter of debate. Purpose of this study is: 1) to assess the feasibility to re-engage coronary ostia after TAVR; 2) to discover potential native anatomical or prosthesis-related features that may preclude proper coronary cannulation after TAVR.
BIOSOLVE-IV Magmaris Swiss Satellite Registry is a prospective, single-arm, multicenter, nationwide open label registry. It is planned to enroll 200 subjects in up to 12 participating sites in Switzerland. After percutaneous coronary intervention (PCI) with the Magmaris scaffold and signature of the informed consent form, all subjects will be followed through hospital discharge and will undergo follow up evaluations at 6, 12 and 24 months post procedure. The follow up evaluations, part of the standard care can be either performed on site (12 months) or by phone (6 and 24 months) and according to routine clinical practice.
Obstructive sleep apnea (OSA) is an increasingly common chronic disorder in adults. Compared to the general population, OSA occurs more often in patients with coronary artery disease (CAD), with a reported prevalence of 38% to 65%. Emerging evidence indicates OSA initiates and exacerbates coronary atherosclerosis. Moreover, several observational studies indicate the presence of OSA was associated with higher rate of restenosis and repeat revascularization (mainly attributed non-culprit lesion revascularization) after percutaneous coronary intervention (PCI). OSA might initiate endothelial injury by repetitive bursts of sympathetic activity that occur with apneas and hypopneas. Moreover, untreated OSA reduces endothelial repair capacity. Whether OSA could exacerbate neointimal proliferation and plaque progression in the non-culprit lesion after drug-eluting stent (DES) implantation remains less studied. The investigators aimed to evaluate neointimal proliferation and strut coverage within stent segment as well as changes of plaque volume and morphology in the non-culprit lesion by optical coherence tomography (OCT) in patients with versus without OSA at 12-month follow-up.
The decision of emergency reperfusion of a suspected acute coronary artery occlusion by means of percutaneous coronary intervention or intravenous thrombolytics depends on the presence of a certain amount of ST-segment elevation in the electrocardiogram (ECG) as recommended by international guidelines. However, recommended ST-segment elevation cut-off values for acute coronary occlusion diagnosis are highly insensitive, and their evidence base is weak. The objective of this study is to test the accuracy of various electrocardiographic patterns (including, but not limited to, ST-segment elevation) for the diagnosis of acute coronary occlusion. This information can serve to offer an accuracy profile for various ECG findings and enable clinicians to define the ECG probability of an acute coronary occlusion according to these ECG findings and clinical picture, which in turn would provide a significant improvement in the care for patients who present to the hospital with possible coronary occlusion. The primary analysis will be designed as a single-center, retrospective case-control study.
stress cMRI with Dobutamine stress agent (stress cMRI), represent the combination of two orders of exams routinely performed (cMRI and stress diagnostic series of exams) without additional risk for the patient, but with the advantage of non-invasiveness and lack of radiation, and less laborious for the participants
A prospective cohort study was performed in patients with angina pectoris who were treated with oral Chinese patent medicine and Western medicine.Collect primary and secondary efficacy indicators such as the incidence of cardiovascular events, using clinical samples to detect genomics, proteomics, metabolomics, intestinal flora and sclerotia.To explore the clinical efficacy of Chinese patent medicine in the treatment of coronary heart disease with angina pectoris, and provide reliable data support for its clinical application.
A total of 106 subjects will be enrolled at up to 3 sites. Initial enrollment will occur at Washington University only. After 15 subjects have been enrolled at the primary site and no serious adverse events or protocol events have occurred the additional sites will be trained and added to enrollment.
Participants aged 80 years or over, who attend Castle Hill Hospital with either stable angina or an acute coronary syndrome will be invited to participate in the study. After induction into the study, these participants will be assessed for frailty and quality of life (QoL) using predetermined assessment tools. Quality of life (QoL) will be assessed using the standardised SF-12 questionnaire proforma. Frailty assessment will be based on the use of the Fried Frailty Phenotype criteria and the Edmonton Frailty Scale. Patients will be reassessed at 3,9 and 24 months for their clinical outcomes, repeat frailty assessment and quality of life.
