In those tolerating the treatment, methimazole significantly reduced the relapse rate the 1st year when given in a high dose. However, the relapse rates in both groups, and the number of side-effects in the high-dose group, were unacceptably high.
Objective-To evaluate the clinical and haemodynamic safety of NC100100, a new transpulmonary ultrasound contrast agent intended for vascular use. Design-Pulmonary artery pressures and gas exchange, left ventricular and systemic blood pressure and ECG were measured at baseline, after saline injection, and after each of two increasing doses of NC100100 injected intravenously. Patients-30 patients who were evaluated for suspected coronary artery disease. Results-No change was detected in any of the haemodynamic variables, or in haematological or clinical chemical parameters. Blood gases were unchanged, as were heart rhythm and arterial oxygen saturation. No serious adverse reactions were reported. Conclusions-NC100100 appeared to be haemodynamically inert and safe in patients with coronary artery disease. (Heart 1999;82:333-335)
In small coronary arteries, both PTCA and elective stenting are associated with good clinical and angiographic outcomes after six months. Compared with PTCA, elective treatment with the heparin-coated beStent improves the clinical outcome; however, there was only a nonsignificant trend toward angiographic improvement.
After 6 weeks on a lipid-lowering diet, 20 outpatients with type II hyperlipoproteinaemia (18 type IIa) were randomized to treatment with cholestyramine 12 g b.i.d. (5 patients) or simvastatin (a new HMG-CoA reductase inhibitor) 40 mg q.p.m. (15 patients) for 12 weeks. From week 13 to week 20 nine patients in the simvastatin group and all patients in the cholestyramine group were treated with the combination of the two drugs. From week 21 to week 52 all patients were on monotherapy with simvastatin. Simvastatin treatment reduced low-density lipoprotein (LDL) cholesterol by 40% after 12 weeks, compared with 33% in the cholestyramine group. This difference was not significant. The total reductions of LDL-cholesterol on combination therapy were respectively 60% and 56% in each group. After 52 weeks LDL-cholesterol was still reduced by 36% (P less than 0.001) on monotherapy with simvastatin. Simvastatin also reduced triglycerides (TG) by 17% (P less than 0.05) and high-density lipoprotein (HDL) cholesterol was increased by 19% (P less than 0.01). No serious side effects were observed, and the new HMG-CoA reductase inhibitors may offer a new approach to the treatment of hypercholesterolaemia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
