Filter by:With the widespread use of clopidogrel, resistance to clopidogrel has been attracting increasing attention, and emerged as a new challenge adversely affecting patients clinical risk and outcome. Clopidogrel resistance means that blood platelets show little or no response to clopidogrel. It is closely associated with increased risk of serious cardiovascular events, seriously affects the prognosis of patients, and brings difficulties to clinical treatment. Guideline recommendations on the use of dual antiplatelet therapy have been formulated that ticagrelor 90 mg twice daily plus aspirin in preference to clopidogrel 75mg daily plus aspirin for ACS patients. Recent study found that ticagrelor 90mg twice a day orally could significantly reduce the occurrence of clopidogrel resistance and adverse cardiovascular events. The previous studies have reported that half-dose ticagrelor had the similar inhibitory effect on platelet aggregation as the standard-dose ticagrelor, which was significantly stronger than that in the clopidogrel group. But it is still not very clear that the effect of low-dose ticagrelor on platelet function in patients with clopidogrel resistance and coronary heart disease. Therefore, we performed this randomized, single-blind clinical trial to observe the effects of low-dose ticagrelor and double standard-dose clopidogrel on platelet aggregation and prognosis in clopidogrel resistance's patients with coronary heart disease.
The optimal antithrombotic treatment for Coronary Heart disease (CHD) patients combined with Atrial Fibrillation (AF) is unresolved at present. Although the European and American guidelines have given a hand for us, there is absence of real-world data on the safety and efficacy of antithrombotic therapy in Asian populations. Only a few clinical trials are available to guide difficult decision on antithrombotic therapy in patients with combined AF and CHD，the investigators highlight the need for the rapid development of clinical trials to close the large gaps in evidence. This research aims to know the real-world use of antithrombotic treatment and clinical prognosis in Coronary Heart Disease patients complicated with Atrial Fibrillation.
The FAMOUS Trial is a single-center, prospective, randomized study aimed to compare three different strategies (clinical, anatomical, or functional) in preventing MACE after CABG. A total of 600 patients will be included and followed for 5 years. Patients will be randomly allocated (1:1:1) in one of the three follow-up strategies. Patients in the clinical arm will be followed by regular medical visits only every 6 months; patients in the functional arm will undergo a myocardial perfusion scan, and those in the anatomical arm will be subjected to a coronary CT. Non-invasive tests will be performed per protocol and regardless symptoms every 2 years after the first year post-surgery. The primary outcome will be the incidence of death, acute myocardial infarction or myocardial revascularization.
The purpose of this study is to determine whether text messages/messaging (TM) or a mobile application (app), compared with an educational website-control provided to all Veterans, can improve adherence to antiplatelet therapy among patients following acute coronary syndrome or percutaneous coronary intervention (ACS/PCI).
1.1 To build a TCM diagnosis and treatment database for chronic stable CAD; 1.2 To summarize the pattern of TCM medicine used and the effect of the medication in chronic stable CAD. 1.3 To formulate a syndrome differentiation determined medicine plan based on the improvement in the quality of life on chronic stable CAD patients.
Patients undergoing Open Cardiac Surgery will be randomized into two groups. Group I will be ventilated with 40% Fio2 during induction, surgery and in Postoperative care unit. Group II will be ventilated with 100% Fio2 during induction and with 60-70% ( determined according to the arterial blood gas sample results) during surgery and in Postoperative care unit. Hemodynamic parameters ( systolic arterial pressure, diastolic arterial pressure, heart rate ), Arterial blood gas samples ( PaO2, PaCO2, pH, Oxygen saturation, Lactate), and pre and post cardiopulmonary bypass Superoxide dismutase and malonyl aldehyde levels.

Rationale: Patients undergoing cardiac surgery are at risk of developing perioperative complications and major adverse cardiac events, mainly related to both their preoperative status and type of surgical procedure. Postoperative exercise based cardiac rehabilitation (CR) is an effective therapy to prolong survival and improve quality of life. However, little is known about the effect on post-operative complications, quality of life and return to work of a combined pre- and post-operative CR program encompassing physical therapy, dietary counseling, psychological support and life style management compared to a CR program, which is provided only after cardiac surgery. Objective: to determine whether a pre- and postoperative (PRE+POST) CR program improves the short (up to three months) and long term outcomes (up to one year) of the cardiac surgery (i.e. reduction in postoperative surgical complications, readmissions to hospital and major adverse cardiac events in conjunction with improvements in the physical component of health related quality of life), when compared to postoperative CR only (POST). Study design: A Prospective Randomized Open controlled trial, Blinded End-point. Patients are randomized between two standard care CR programs. One group will start a the POST CR program after surgery. The other group will be randomized to a combined PRE+POST CR program. Study population: Patients (age > 18 years) admitted for elective coronary bypass surgery, valve surgery and/or aortic surgery Main study parameters/endpoints: The primary outcome is a composite weighted endpoint of postoperative surgical complications, re-admissions to hospital, major adverse cardiac events and health related quality of life (two domains: physical functioning and physical problem), at three months and one year after surgery. Endpoints are determined by an independent endpoint committee, blinded to the group allocation. Secondary, the study focuses on physical health (cardiorespiratory fitness, muscle strength and functional status), psychological health (feelings of anxiety and depression), work participation, economics, lifestyle risk factors (physical activity and smoking behavior), self-efficacy and illness representations.
Coronary heart disease is still the major cause of death in China. Chinese medicine plays more and more important role in CHD prevention and treatment. Phlegm and blood stasis are its major pathological basis. Based on that, the investigator aims to evaluate the evolutionary process of CHD phlegm-blood stasis syndrome by large samples, multi-centre, cross-section observation combining with longitudinal tracking on-site survey method so as to guide the clinical treatment of CHD.
