Filter by:Coronary heart disease(CHD), stroke, and hypertension are major diseases that seriously affect human health.Pathologic changes in the arteries involved in the above diseases mainly occur in the intimal or medial layer of the arteries. Among them, cardiovascular and cerebrovascular diseases (CHD and stroke) have become the top two causes of death worldwide, with elderly patients accounting for the vast majority. CHD is an important cause of death, and atherosclerosis (AS) is the main pathology underlying it.AS predominantly occurs in the intima layer, and the use of high-resolution imaging techniques to visualize anatomical changes in the intima-media layer of the arteries alone is valuable for the study of AS. Coronary computed tomographic angiography (CCTA) and intracranial vascular magnetic resonance angiography (MRA) can clearly visualize coronary and intracranial arterial lesions, measure luminal stenosis and other important information, and provide a basis for diagnosis, treatment and prognosis of the disease. By integrating CCTA/MRA/Ultrasound multimodal imaging technology, investigators aim to develop a non-invasive CHD and stroke intelligent screening and evaluation system, which is bound to have great clinical and social value. This study is a national multi-center follow-up observational study, which is expected to collect and establish a database of clinical and imaging information of no less than 20,000 cases of elderly subjects. Some data is derived from the pre-established database (>12,000 cases) in cooperative research centers, while additional data will be collected from the newly established prospective follow-up database. Investigators performed noninvasive high-frequency ultrasound to detect arterial vascular structural changes, vascular dynamics and other indicators based on the existing database and the newly established imaging database to explore the characteristics of carotid atherosclerosis changes and ultrasound monitoring methods in the elderly. Finally, investigators integrated clinical and multimodal noninvasive imaging information to construct a noninvasive imaging-based intelligent risk assessment system for CHD and stroke. Primary endpoint was the cardiovascular-complex endpoint event,including myocardial infarction, cardiovascular death, resuscitation with cardiac arrest, revascularization, and stroke. Secondary endpoint was vascular lesion progression, including increase of vascular intima thickness, increase of vascular media thickness, plaque progression, and increase of vascular stenosis. All enrolled patients were followed up every six months to record whether the primary endpoint and secondary endpoint events occurred and to record the time and type of occurrence.
Background: Clinical trials often include patients from large hospitals or university clinics. Information on patients cared for at offices from statutory health insurance-accredited physicians represent evidence gaps. Aims/Objectives: The present study has three aims: First, to systematically describe the patient population of a large group practice for internal medicine. Second, to identify high-risk patients using established risk scores. And third, to include routine imaging data to optimize patient management. Methods/Facility Enrolling Participants: This is a prospective, observational study assessing patients' baseline characteristics, risk evaluation and integrating data from imaging test. The setting of the present study is a large group practice for internal medicine which consists of statutory health insurance-accredited physicians. Study participants will be included during daily routine, real-world clinical care and therefore represent all-comers fulfilling the inclusion criteria: 1. Female or male patients aged above 18 years diagnosed with chronic liver disease, undergo on-site endoscopy, suffer from atherosclerosis, heart failure, are diagnosed with abnormal serum thyroid-stimulating hormone (TSH) levels, either overt or latent hypo- or hyperthyroidism, or are diagnosed with solitary or multiple thyroid nodules. 2. Routine laboratory results available within the last 3 months. 3. Available imaging data within the last 3 months performed on site. Perspective: The study is designed to evaluate the current situation and quality of health care in defined patient populations in the routine clinical setting of a large-scale public office. These data will provide a profound rationale to identify quality issues and limitations in our performance of guideline-conform treatment in routine patient care.
The goal of this clinical trial is to explore the influence of chronic RIC on collateral status evaluated by DSA in ischemic stroke patients with LAA etiology.
The purpose of this study is to evaluate the safety and efficacy of urinary kallidinogenase treatment in patients with large artery atherosclerotic acute ischemic stroke.
LTF-001 is a long-term follow-up study of participants who received an investigational gene-editing therapy developed by the sponsor to evaluate the long-term effects of the investigational therapy. Participants will be followed for a total of 15 years after the first administration of the gene-editing therapy, including time in both the interventional study and study LTF-001.
The goal of this clinical trial is to test the effect of proprotein convertase subtilisin/kexin type 9 (PCSK9 inhibitors) in acute ischemic stroke patients associated with atherosclerosis by investigating 1. the change in lipid profile compared to baseline results 2. the effects on prognosis of stroke The participants will be given PCSK9 inhibitor right after confirmation of acute ischemic stroke, and the investigators will compare the results to the control group, whom are acute ischemic stroke patients treated with conventional lipid lowering therapy, statin and/or ezetimibe.
The primary goal of the trial is to investigate whether the lipid lowering strategy using Alirocumab plus statin could cause more changes from baseline in intracranial atherosclerotic plaque and hemodynamic features during 6 months of follow-up, in patients with asymptomatic intracranial artery stenosis.
The goal of this phase 2, before-and-after interventional study is to investigate the effect of colchicine treatment on serum biomarkers of inflammation in patients with a history of stroke and atherosclerosis. Participants meeting inclusion criteria will have blood samples drawn at baseline, will be dispensed colchicine 0.5mg daily for a treatment period of 30 days and have blood samples drawn again at follow-up. All blood samples will be analysed for a panel of inflammatory blood markers and the change in blood inflammatory markers from baseline to end of treatment will be calculated.
The present study sought to explore the predictive value of radial wall strain (RWS, derived solely from angiograms) for coronary artery lesion progression compared with lesion vulnerability assessed by optical coherence tomography (OCT). The lesion progression at 1 year was defined as an increase of ≥20% in diameter stenosis based on quantitative coronary angiography (QCA) evaluation.
This trial will investigate whether notifying patients and their clinicians of the presence of moderate or severe coronary artery calcium on a low-dose CT scan performed for lung cancer screening results in a lower incidence of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke as compared with usual care informed by clinical practice guidelines.
