Study Overview
Brief Summary
Colchicine has antiinflammatory properties. It has been shown to be effective in improving outcome in stable coronary disease. The exact mechanism is unclear. Study objective: to assess the effect of colchicine on endothelial function using the EndoPAT™ in NSTEMI Patients.
Study Hypothesis: There will be a significant difference on the RH-PAT levels of the patients who were in treated with colchicine versus the placebo group Study design and patient Selection One hundred and forty patients with the diagnosis of Non ST Elevation Myocardial Infarction will be enrolled to a prospective randomized double-blind placebo controlled study in Tel Aviv Medical Center, Tel Aviv, Israel. Patients will be recruited during their hospitalization before cardiac catheterization. All patients will sign an informed consent.
Primary outcome will be the improvement in endothelial function between baseline and after 1 month in both groups
Detailed Description
Study design and patient Selection One hundred and forty patients with the diagnosis of Non ST Elevation Myocardial Infarction (NSTEMI) will be enrolled to a prospective randomized double-blind placebo controlled study in Tel Aviv Medical Center, Tel Aviv, Israel. Patients will be recruited during their hospitalization before cardiac catheterization. All patients will sign an inform consent. Study will be published on NIH clinicaltrials.com database.

Outcomes
Primary Outcomes
Improvement of RH-PAT at 1 month (a marker of endothelial function)
Time Frame: 1 month
RH-PAT will be measured before the angiography and after one month.

- Improvement in endothelial function markers.(1 month)
- Improvement in inflammatory biomarkers (before cardiac catheterization, after cardiac catheterization and at 1 month time follow-up)(1 month)
- Changes in cholinergic status(1 month)
- Reduction in radial artery occlusion(acute)
- inflammatory biomarkers Improvement of heart rate variability (HRV)(1 month)
- Reduction of Acute Kidney Injury post PCI(1 month)
- Major adverse clinical events (MACE) defined as a composite of all-cause mortality, myocardial infarction, repeat revascularization, and 30 day readmission rate(1 month)
- quality of life under colchicine treatment(1 month)
