Objective To observe the effect of intraaortic balloon pump (IABP) on tolerance of percutaneous coronary intervention (PCI), life signs of patients with acute myocardial infarction (AMI) during emergency PCI performed.Methods46 AMI patients complicated with or without cardiogenic shock were put on IABP at same time of coronary angiography when emergency PCI performed, and tolerance of PCI, blood pressure, heart rate and immediate death rate of patients were observed before and after operation.Results45 cases had IABP successful and 1 case failed. 40 patients (86.96%) could endure whole emergency PCI process, the total death rate was 10.87%. 66.67% of patients with obvious cardiogenic shock could endure emergency PCI, the death rate was 33.33%; 94.12% of patients without cardiogenic shock could endure PCI treatment and the death rate was 2.94%. 35 cases completed PCI treatment and the successful rate was 85.36%.ConclusionPCI supported by IABP can prevent AMI patients from cardiogenic shock, ease symptoms of patients complicated with cardiogenic shock, improve the tolerance and successful rate of the PCI treatment, and decrease immediate death rate.

The arterial lesions of lower extremities in patients with diabetic foot ulcers were extensive.The majority of below-knee arteries showed severe stenosis, even complete occlusion.Interventional therapy of femoral artery was effective in improving arterial blood perfusion and remission of the pain and numbness.After therapy, the skin temperature and ankle brachial index (ABI) were increased, healing of ulcer was enhanced and intermittent claudication was ameliorated.Percutaneous transluminal angioplasty of femoral artery was effective in improving arterial blood perfusion of the lower extremities with foreseen curing efficacy.

Congenital heart disease is the most common birth defect in China, of which heart valve dysplasia is an important phenotype.Heart valve development is an important process of embryonic development, which is regulated by a variety of signaling pathways.If the process of proliferation, differentiation or migration of endothelial cells and cardiomyocytes is abnormal, the heart valve will develop abnormally and the valvular heart disease may occur.Tissue explant systems and various animal model experiments have demonstrated that multiple signaling pathways interact to form a vast regulatory network that collectively regulates the development of heart valves.This review will highlight the nost intensively studied signaling pathways in epithelial-mesenchymal transition, including VEGF, NFATc1, Notch, Wnt, TGF-β, ErbB, and NF1 signaling pathways.

Giant coronary aneurysm is the most severe complication of Kawasaki disease and is the leading cause of cardiovascualr events, which can cause coronary artery stenosis, thromboembolism, myocardial ischemia and even death.We aim to improve the prognosis of the patients with sever coronary artery lesions by comprehensive management including active anti-inflammatory and antithrombotic therapy in acute and subacute phase, as well as optimal treatment and follow-up plan according to morphologic evaluation of coronary artery lesions and myocardial ischemia after convalescent period.
