Randomized Controlled Trial Comparative Study Clinical TrialEffect of intravenous metoprolol before hospital admission on chest pain in suspected acute myocardial infarction.
The aim of this study was to describe the effect of intravenous metoprolol on the intensity of chest pain before hospital admission in patients with suspected acute myocardial infarction AMI). ⋯ When all patients were included in the analyses, there was no significant difference with regard to reduction of chest pain in the patients randomly assigned to metoprolol compared with placebo. A retrospective subgroup analysis indicated a beneficial effect of metoprolol among patients with an initially strong suspicion of or confirmed AMI. Further investigations are warranted to confirm this finding.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialAntianginal efficacy of the combination of felodipine-metoprolol 10/100 mg compared with each drug alone in patients with stable effort-induced angina pectoris: a multicenter parallel group study. The TRAFFIC Study Group.
The primary objective of this randomized, double-blind, parallel group trial was to compare the antianginal and antiischemic efficacy of a combination tablet of felodipine-metoprolol 10/100 mg once daily with both drugs given separately once daily in patients with stable effort-induced angina pectoris. The secondary objective was to compare the tolerability of the 3 treatments. ⋯ In stable angina pectoris, the combination felodipine-metoprolol 10/100 mg and felodipine 10 mg alone increased exercise time compared with metoprolol 100 mg. The combination tablet and metoprolol 100 mg alone showed a more favorable tolerability profile than felodipine 10 mg alone.
