Brief Summary

The OPERA-MI trial evaluates the effect of i.v. ferric carboxymaltose compared to the effect of oral iron, on left ventricular systolic function.

Detailed Description

For this study an open-label prospective randomized approach is used. During the study 360 patients with or without ID, who hospitalized for myocardial infarction were signed up. Patients were randomised (1:1) to either intravenous. FCM or oral ferrous sulphate and received the treatment during hospitalisation. Patients are closely followed for 1 year. The primary outcome is a decrease in the Wall Motion Score Index value in FCM group compered to ferrous sulphate group. The main secondary outcome includes the composite of cardio-vascular mortality, non-fatal stroke, non-fatal MI, recurrent heart failure hospitalizations.

Conditions

Myocardial Infarction; Iron-deficiency

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

FCM group

The ferric carboxymaltose doses were determined using the patient's screening visit body weight measurement and haemoglobin value. Patients receives all doses during hospitalization accordance with the drug local labels.

Group Type: ACTIVE_COMPARATOR

ferric carboxymaltose

Intervention Type: DRUG

ferric carboxymaltose is i.v. iron, 99 patiants will be randomised to this group

Ferrous sulphate group

100 mg of ferrous sulphate is administrated 2 times per day during hospitalization and continue within next 2 month.

Group Type: ACTIVE_COMPARATOR

ferrous sulphate

Intervention Type: DRUG

ferrous sulphate is oral iron, 100 patiants will be randomised to this group

Group with normal iron status

Patiants with normal iron status

Group Type: NO_INTERVENTION

No interventions assigned to this group
