Many patients are not suitable for percutaneous or surgical revascularization because of unfavourable anatomy, or the presence of co-morbidities. In addition, many patients have recurrence of angina following revascularization due to restenosis or incomplete revascularization. Furthermore, randomized clinical trials comparing optimal medical treatment to revascularization have not clearly shown that myocardial revascularization is superior to optimal medical treatment. Traditional drugs for angina treatment include b-blockers, calcium channel blockers and nitrates. Newer drugs are available with different mechanisms of action and with equal efficacy that do not cause significant hemodynamic deterioration. The availability of these newer drugs expands the therapeutic potential of medical treatment to even a wider population with stable IHD. Revascularization in patients with stable ischemic heart disease has never been shown to reduce hard endpoints (death or myocardial infarction) in randomized clinical trials.展开更多

How...Antiplatelet therapy with aspirin or clopidogrel or both is the standard care for patients with proven coronary or peripheral arterial disease,especially those undergoing endovascular revascularization procedures. However,despite the administration of the antiplatelet regiments,some patients still experience recurrent cardiovascular ischemic events. So far,it is well documented by several studies that in vitro response of platelets may be extremely variable. Poor antiplatelet effect of clopidogrel or high on-treatment platelet reactivity(HTPR) is under investigation by numerous recent studies. This review article focuses on methods used for the ex vivo evaluation of HTPR,as well as on the possible underlying mechanisms and the clinical consequences of this entity. Alternative therapeutic options and future directions are also addressed.展开更多

This study is aimed to investigate an additional therapy affects the risk for CAL in IVIG resistant KD. Design: The information from 11,510 children with KD was collected by the nationwide survey (2003-2004) in Japan. The secondary therapeutic strategies for IVIG resistant KD were an additional IVIG dose, steroids or both. The incidence of CAL was compared among 4 groups: G1, children responded to initial IVIG;G2, IVIG resistant patients receiving an additional IVIG dose;G3, IVIG resistant patients receiving additional steroids;G4, IVIG resistant patients receiving an additional IVIG dose plus steroids. CAL was assessed at 30th day of illness using ultrasound echocardiography. Results: 2229 patients (19.4%) were resistant to initial IVIG. Incidence of CAL was significantly lower in children responding to initial IVIG than in IVIG resistant patients (1.9% and 11.0%, respectively;odd’s ratio 6.3). The incidences of CAL in an each additional therapy group were as follows: G2: 6.7%, G3: 9.7%, G4: 22.2%. The risk for CAL was significantly higher in G4 as compared with G2 and G3. Giant aneurysmal formation (GA) was more frequently developed in G3 and G4 consisting of the patients receiving steroids (G1: 0.03%, G2: 0.63%, G3: 4.3%, G4: 3.7%). Conclusion: The incidence of CAL was considerably high in IVIG resistant KD and an additional therapy by steroids may increase the risk for GA.展开更多
