Plain English Summary

Background and study aims
When your heart is injured due to a serious heart attack, it sets off an immediate inflammatory response. If the blood flow isn't quickly restored, the damaged tissue can turn into scar tissue. In people with a specific kind of heart attack, called STEMI, restoring blood flow promptly is crucial to minimize damage. This can be done either by using a procedure called PCI or by using fibrinolytic therapy.
Sometimes, even when the blood flow is restored, there can be ongoing damage to the heart tissue. This damage involves changes in tiny structures within the cells, leading to inflammation. Certain cells in the immune system, called macrophages, get involved, releasing substances that either promote or reduce inflammation. In this study, we're looking at a drug called colchicine, known for its anti-inflammatory properties. It seems that colchicine may not only reduce inflammation but also prevent the formation of excess scar tissue in the heart.
Our goal is to understand how colchicine affects specific processes in the body after a heart attack, particularly in patients who undergo a procedure to restore blood flow. We're investigating whether colchicine can decrease the harmful effects of inflammation, promote healing, and potentially prevent heart failure from developing. We're also using a substance called NT-proBNP to help us understand the extent of heart damage. By doing this research, we hope to find new ways to improve outcomes for people who experience this type of heart attack.

Who can participate?
Patients aged 30-75 years, diagnosed with acute myocardial infarction, who have undergone reperfusion therapy and are receiving colchicine treatment in addition to the standard of care, and meet the inclusion criteria.

What does the study involve?
The study involves administering colchicine to reduce cardiac fibrosis by increasing levels of IL-10 and galectin-3 and reducing the ratio of collagen I to collagen III and NT-proBNP. The treatment's effectiveness will be assessed using various biomarkers and echocardiography.

What are the possible benefits and risks of participating?
The benefits of participating in this study include the potential reduction of fibrosis and anti-remodeling effects. However, there are risks involved, such as side effects from colchicine, including nausea, diarrhoea, and gastritis.

Scientific titleInhibition of cardiac fibrosis by colchicine through differential increase in interleukin-10 and galectin-3 expression and decrease in the ratio of collagen I to collagen III and NT-proBNP in acute myocardial infarction (in vivo study on patients with acute myocardial infarction with ST-segment elevation undergoing primary and delayed percutaneous coronary intervention)
Study acronymICFC-AMI
Study hypothesisIt is hypothesized that there is a difference in the effect of colchicine administration in inhibiting cardiac fibrosis through an increase in IL-10 and galectin-3 levels, and a decrease in the ratio of collagen I to collagen III, evaluated by PIIINP (Procollagen 3 N-terminal peptide) and NT-proBNP (N-terminal pro b-type natriuretic peptide), in patients with acute myocardial infarction with ST-segment elevation (STEMI) undergoing primary and delayed percutaneous coronary intervention
Ethics approval(s)

Approved 05/11/2020, Health Research Ethics Committee. General Hosptal Dr. Saiful Anwar Malang (Jl. Jaksa Agung Suprapto no 2. Malang, Malang, 65111, Indonesia; +62 (0)341362101; staf-rsu-drsaifulanwar@jatimprov.go.id), ref: 400/K.3/302/2020

ConditionAcute myocardial infarction
InterventionPatients undergoing primary and delayed percutaneous coronary intervention (PCI) are divided into two groups for each PCI type. Sample selection is through consecutive sampling, and randomization is 1:1 with double-blind allocation.

Primary PCI patients:
1. One group receives a loading dose of 1 mg colchicine 1-2 hours before the PCI procedure, followed by 0.5 mg 1 hour afterwards, and a maintenance dose of 0.5 mg daily for 1 month, along with optimal medical therapy.
2. The other group receives a placebo following the same regimen and optimal medical therapy for 1 month.

Delayed PCI Patients:
1. One group receives a loading dose of 1 mg colchicine 1-2 hours before the PCI procedure, followed by 0.5 mg 1 hour afterwards, and a maintenance dose of 0.5 mg daily for 1 month, along with optimal medical therapy.
2. The other group receives a placebo following the same regimen and optimal medical therapy for 1 month.

This design allows the researchers to observe the effects of colchicine in comparison to placebo in patients undergoing different timings of PCI while ensuring that all groups receive the standard care.
