Background: Coronary tomography angiography (CTA) has been mainly used for chest pain evaluation in low-risk patients, and few data exist regarding patients at intermediate risk.
Objective: To evaluate the performance of serial measures of sensitive troponin and CTA in intermediate-risk patients.
Methods: A total of 100 patients with chest pain, TIMI risk scores of 3 or 4, and negative troponin were prospectively included.
Importance: Short-term infusions of single vasodilators, usually given in a fixed dose, have not improved outcomes in patients with acute heart failure (AHF).
Objective: To evaluate the effect of a strategy that emphasized early intensive and sustained vasodilation using individualized up-titrated doses of established vasodilators in patients with AHF.
Design, Setting, And Participants: Randomized, open-label blinded-end-point trial enrolling 788 patients hospitalized for AHF with dyspnea, increased plasma concentrations of natriuretic peptides, systolic blood pressure of at least 100 mm Hg, and plan for treatment in a general ward in 10 tertiary and secondary hospitals in Switzerland, Bulgaria, Germany, Brazil, and Spain.
Aims: We sought to evaluate the effects of trimetazidine on ischemia induced by dobutamine-atropine stress echocardiography in patients with class I or class II angina.
Methods: In a randomized, double-blind, placebo-controlled study, 66 patients with proved coronary disease were subjected to dobutamine-atropine stress echocardiography. Ischemia was proved in 56 patients who were included in the study and who had been on standard maintenance medications (propranolol, aspirin and statin).
