Filter by:The prognostic factors after a percutaneous coronary intervention (PCI) have not been comprehensively investigated. The investigators sought to develop a risk model to predict future clinical events after PCI using contemporary coronary stents.
Recent studies indicate that anti-factor-Xa inhibition with low-dose rivaroxaban may have a role in the reduction of ischemic recurrences in patients with atherosclerotic disease manifestations. The objectives of this investigation are to assess the feasibility of switching from a DAPT to DPI regimen and to compare the pharmacodynamic profiles of these treatment regimens. This will be a prospective study conducted in cohorts of patients with CAD on treatment per standard of care with DAPT. Patients will be randomized to either maintain DAPT or to DPI. DPI consists in treatment with aspirin (81mg/qd) plus rivaroxaban (2.5mg/bid).
Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor reduces thrombotic events in patients with coronary artery disease, but these benefits come at the expense of increased risk of bleeding when compared with aspirin monotherapy. Increased evidence showed that P2Y12 inhibitor monotherapy still maintain antiischemic efficacy while reducing the bleeding risk compared with DAPT. Therefore, the investigators performed this study to observe the efficacy of ticagrelor in comparison to clopidogrel in Chinese patients with stable CAD.
This single-center clinical trial is designed to evaluate the CardioFlux magnetocardiograph diagnostic imaging system to predict major adverse cardiac events (MACE) in patients referred for evaluation for coronary artery disease.
In the middle of this century, coronary heart disease (CHD) is the most common cause of death in the United States. Chinese health service survey showed that about 1000,0000 ~ 320,000 people were suffering from CHD in the mainland of China in 2008. The high mortality and morbidity of CHD will aggravate the psychological burden of patients, such as depression. Depression is the most psychological problem in CHD patients. The incidence of depression in Chinese population was in the range of 4%~6%, while it was as high as 14%~17% in patients with CHD. Depression not only affects the patients' illness, but also reducing their quality of life, the compliance of drugs and lifestyle. In addition, depression is a major risk factor for the mortality and morbidity of cardiovascular disease. Therefore, it's urgently needed to screen and treat the depression of patients with CHD. At present, the treatment of depression in patients with CHD mainly includes antidepressant, cognitive behavioral therapy， psychological counseling, knowledge education, relaxation therapy and so on. However, the medicine would yield side - effect. Furthermore, the content of psychological interventions are not systematic and dynamic. Moreover, patients' depressive level varies in different periods, the traditional psychological intervention just focused on the ultimate psychological benefits, and cannot analyze some factors and staged results in the process of psycho-behavioral change. Thus, an dynamic and effective intervention to alleviate depression in patients with CHD is imperative.
Improving physical activity is a core component of secondary prevention and cardiac (tele)rehabilitation. Commercially available activity trackers are frequently used to monitor and promote physical activity in cardiac patients. However studies on the validity of these devices in cardiac patients are scarce. The aim of this study is to determine the accuracy and responsiveness of two wrist-worn activity trackers, Fitbit Charge 2 (FC2) and Mio Slice (MS), for the assessment of energy expenditure (EE) in cardiac patients.
Coronary artery disease and the benefit of bypasses: Despite considerable advances in medicine, cardiovascular diseases remain the number one cause of death globally, primarily consequence of myocardial infarction (MI). Coronary collaterals exert a protective effect by providing an alternative source of blood flow to a myocardial territory potentially affected by an acute coronary occlusion. Coronary collaterals represent pre-existing inter-arterial anastomoses and as such are the natural counter-part of surgically created bypasses. Sufficient coronary collaterals have been shown to confer a significant benefit in terms of overall mortality and cardiovascular events. In this regard, the concept of augmenting coronary collateral function as an alternative treatment strategy to alter the course of CAD, as well as to control symptoms, is attractive. Durable promotion of coronary collateral circulation: Before the advent of coronary artery bypass grafting, permanent augmentation of coronary collateral supply by a single structural modification has already been attempted. Bilateral ligation of the internal mammary arteries (IMA) was performed in CAD patients to alleviate angina pectoris and electrocardiographic (ECG) signs of ischemia. The prevalent in vivo function of natural internal mammary arteries (IMA)-to-coronary artery bypasses and their anti-ischemic effect has been recently demonstrated by the investigators' research group. Levels of collateral function and myocardial ischemia were determined in a prospective, open-label clinical trial of permanent IMA device occlusion. In this study, coronary collateral function, has been shown to be augmented in the presence vs the absence of distal permanent ipsilateral IMA occlusion. These findings have been corroborated by the observed reduction in ischemia in the intracoronary ECG. After this first step, the concept of permanent right IMA occlusion will be now investigated with a randomized, sham-controlled clinical trial.
Background: It has been demonstrated that pre-frailty has more adverse outcomes after cardiac surgery, however, data on prognosis and long-term evolution in pre-frailty patients after cardiac surgery without postoperative complications are still scarce. Design: To evaluate the impact of pre-frailty on functional survival in patients after cardiac surgery without complications.
Introduction: The distal radial technique which consists of canalizing the radial artery through the anatomical snuffbox has recently emerged as an alternative arterial intervention for diagnostic and therapeutic coronary catheterization. Aims: To evaluate the feasibility and safety of the distal transradial approach (dTRA) as a default route for coronary angiography (CAG) and percutaneous coronary intervention (PCI).
Patients with lower extremity peripheral artery disease (PAD) are at risk of developing major adverse limb events and have a similar cardiovascular (CV) morbidity and mortality to those with coronary artery disease (CAD) with which is associated in most cases with a more severe prognosis. Because of higher risk conferred by concomitant PAD an early diagnosis is recommended in subjects with CAD. PAD can be diagnosed relatively easily and noninvasively with the ankle-brachial index (ABI) measure. An ABI ≤0.9 is an indicator of the presence of lower extremity PAD, indicating athero-occlusive arterial disease while >1.3/1.4 indicates an incompressible ankle arteries. However, ABI is not routinely applied in the clinical practice. Data on prevalence of PAD are scanty and in patients with stable CAD are lacking. The under-diagnosis of PAD may be a barrier to the use of treatments to improve prognosis. The primary aim of this study is to assess the coexistence of PAD in subjects with stable CAD and to evaluate the management and the prognosis of these patients in primary care at 12-month after the inclusion in the study.
