- A total of 1395 patients aged 40 to 74 years were included in a double blind trial with the beta 1 selective blocker metoprolol in suspected acute myocardial infarction. Metoprolol was given intravenously (15 mg) as soon as possible after admission to hospital followed by 200 mg daily for three months. A placebo was given in the same manner. The severity of chest pain in the acute phase was calculated by recording the number of injections of analgesics given and the time from the start of blind treatment to the time when the last analgesic was given (duration of pain). The patients receiving metoprolol were given a lower mean number of injections of analgesics during the first four days and after randomisation than those receiving a placebo. The estimated duration of pain was shorter in the metoprolol group than in the placebo group. These effects were related to the initial heart rate, the initial systolic blood pressure, and the final site of the infarct as determined electrocardiographically. Thus metoprolol given in the acute phase of suspected or definite myocardial infarction appears to reduce the severity of chest pain.

- Heart rate, systolic blood pressure and rate-pressure product were analyzed during the first 18 hours and 4 days after intravenous metoprolol or placebo. On injection of metoprolol there was an immediate decrease in mean heart rate from 72.9 0.6 to 62.7 0.4 beats/min, but no change was found in the placebo group. The difference in heart rate remained during the first 4 days. Systolic blood pressure was reduced from 144.1 0.9 to 134.6 0.9 mm Hg after intravenous metoprolol and was lower than that in the placebo group during 4 days of follow-up. Indirect signs of congestive heart failure tended to be less severe in patients given metoprolol within 12 hours of the onset of symptoms than in those given placebo. The duration of hospitalization also tended to be shorter in patients given early metoprolol treatment than in those given placebo early.

Göteborg Metoprolol Trial : mortality and causes of death

- During the 3-month blind treatment period there were 40 deaths in the metoprolol group compared with 62 deaths in the placebo group (p = 0.024). During the first year (after 3 months the 2 groups were treated similarly) there were 64 deaths in the metoprolol group vs 93 in the placebo group (p = 0.017) and during 2 years 92 patients died in the metoprolol group vs 120 in the placebo group (p = 0.043). The relative incidence of different causes of death did not differ significantly between the 2 treatment groups, indicating that metoprolol reduced all causes of death to the same extent as its effect on overall mortality.

Göteborg Metoprolol Trial : design, patient characteristics and conduct

Tidskriftsartikel (refereegranskat)abstract
- The Göteborg Metoprolol Trial was a double-blind, placebo-controlled, stratified trial aimed at evaluating the effect of the beta 1-selective blocker, metoprolol, in suspected acute myocardial infarction and during 2 years of follow-up. The primary end-point was 3-month mortality (blind treatment period). Secondary end-points were 2-year mortality, indirect signs of infarct size, chest pain, arrhythmias and tolerability. The entry criteria were fulfilled in 2,802 patients, 1,395 of whom were included in the trial. Treatment started as soon as possible after arrival in hospital with intravenous administration followed by oral treatment for 3 months. All patients were randomized 48 hours or less after estimated onset of infarction and 69% were randomized at 12 hours or less. The blind treatment had to be withdrawn in 19% of all randomized patients before the end of the 3-month follow-up.

- Objective: To examine whether blood pressure over 24 h differed between postmenopausal women receiving and not receiving hormone replacement therapy. Methods: One group of hormone replacement postmenopausal women (n = 32) and one group of non-hormone replacement (n = 32) postmenopausal women underwent non-invasive 24-h ambulatory blood pressure monitoring. They were randomly selected among the 2000 firstly screened women in an ongoing project in Lund, Sweden. The study was designed to detect a difference of 5 mmHg in diastolic blood pressure over 24 h with a power of 80% and 5% significance (two-tailed test). Results: The hormone replacement women had a mean (SD) office blood pressure of 128/76 (12/8) mmHg and the non-hormone replacement 126/78 (16/8) mmHg. Mean ambulatory blood pressure over 24 h, day and night, in the hormone replacement group was 121/72 (11/7), 126/76 (12/8), 111/64 (11/7) mmHg. The corresponding values in the non-hormone replacement group were 118/72 (12/7), 124/77 (12/7), and 107/64 (13/7) ( p > 0.40 for diastolic blood pressure and p > 0.20 for systolic blood pressure). Mean heart rate over 24 h was 71 (7) and 73 (8) beats/min in the hormone and non-hormone replacement groups, respectively. Conclusion: There was no difference in blood pressure or heart rate between the hormone replacement and non-hormone replacement postmenopausal women, either over 24 h or during the day or night. Hormone replacement in postmenopausal women seems not to have an influence on blood pressure, but of course we are aware that this is a cross-sectional study, which has its limitations.

Göteborg Metoprolol Trial : tolerance
- 1984

- During a 3-month follow-up, 131 patients (19.1%) withdrew from blind treatment in both metoprolol- and placebo-treated groups. More metoprolol-treated than placebo-treated patients withdrew because of cardiovascular adverse experience mainly during the very early phase. In all, 45 (6.5%) metoprolol-treated vs 14 (2.0%) placebo-treated patients were not given either a full intravenous dose or a full oral dose 15 minutes later. Bradycardia and hypotension were more common in the metoprolol group, whereas severe atrioventricular block did occur in a similar number of patients in both groups and severe congestive heart failure was more common in the placebo group. Results indicate that tolerance is generally good after intravenous and oral treatment with metoprolol in patients with suspected acute myocardial infarction.
