OBJECTIVE Widespread death of implanted cells hampers stem cell therapy for acute myocardial infarction (AMI). Based on the pleiotropic beneficial effects of statins, we examined whether simvastatin (SIMV) increased the efficacy of mesenchymal stem cell (MSC) transplantation after AMI. METHODS AND RESULTS Chinese miniswine (n=28) were randomized to 1 of 4(More)
AIMS To investigate whether Atorvastatin (Ator) treatment improves the cardiac micro-environment that facilitates survival and differentiation of bone-marrow-derived mesenchymal stem cells (MSCs) implanted in the post-infarct myocardium. METHODS AND RESULTS Myocardial infarction was created by coronary ligation and immediately after reperfusion,(More)
BACKGROUND Coronary artery disease (CAD) is generally considered as a disease of middle-aged men. It is widely accepted that the risk for CAD of premenopausal women is low because of hormone protection. Based on our clinical experience, more and more premenopausal women suffer from angina and myocardial infarction without adequate concern. Even now, there(More)
UNLABELLED We have recently demonstrated the potential of (18)F-FDG as an imaging marker of myocardial ischemia if injected at peak exercise. However, how long increased (18)F-FDG uptake can be observed after an episode of exercise-induced myocardial ischemia is not known. We performed the current study to determine whether increased regional myocardial(More)
BACKGROUND Our previous studies have demonstrated that Tongxinluo (TXL), a traditional Chinese medicine, can protect hearts against no-reflow and reperfusion injury in a protein kinase A (PKA)-dependent manner. The present study was to investigate whether the PKA-mediated cardioprotection of TXL against no-reflow and reperfusion injury relates to the(More)
BACKGROUND AND AIM Previous studies have documented the prognostic value of normal exercise Tl myocardial perfusion imaging in patients with angiographic coronary artery disease (CAD). However, data on exercise Tc-sestamibi myocardial single photon emission computed tomography (SPECT) are scant. Accordingly, the purpose of this study was to investigate the(More)
The case is a 54-year-old man with hypertrophic cardiomyopathy, mid-ventricular obstruction, apical aneurysm, and recurrence sustained monomorphic ventricular tachycardia (VT). A coronary angiogram revealed myocardial bridging located in the middle of the left anterior descending coronary artery (LAD), and the left ventriculogram showed an hour-glass(More)
BACKGROUND Recent data have shown that sirolimus-eluting stents (SES) reduced not only the incidences of restenosis but also of target vessel revascularization (TVR). CYPHER and FIREBIRD stents are both widely used SES in China. However, comparative data concerning differences in long-term safety and efficacy regarding CYPHER and FIREBIRD stents in the(More)
BACKGROUND Recent studies have shown that drug eluting stent (DES) implantation improved clinical outcome concerning efficacy compared with bare-metal stent (BMS) implantation, and sirolimus-eluting stent (SES) seemed superior to paclitaxel-eluting stent (PES) in improving the outcomes. Firebird SES is the most widely used SES in China. Long-term comparison(More)
Coronary arteries may be involved in some patients with Takayasu arteritis. Evaluation of myocardial involvement due to coronary lesions may provide important information in the clinical management of these patients. We report Tc-99m sestamibi and F-18 FDG myocardial single photon emission computed tomography in 3 cases of such patients.
