Colchicine Protective Effect in Patients Undergoing Percutaneous Coronary Intervention (COLCHICINE-PROTECT)
- Conditions
- Coronary Artery Disease
- Interventions
- Drug: Placebo
- Registration Number
- NCT05739929
- Lead Sponsor
- Helwan University
- Brief Summary
The goal of this clinical trial is to evaluate the colchicine protective effect in patients undergoing Percutaneous Coronary Intervention (PCI). The main question it aims to answer is: does initiating colchicine before planned PCI will reduce post-procedural myocardial injury? Half of the participants will receive colchicine, while the other half will receive a placebo.
- Detailed Description
Inflammation in the setting of PCI is associated with endothelial dysfunction and microvascular obstruction and remains an independent predictor of subsequent major adverse cardiovascular events (MACE) even in the contemporary era of second-generation drug-eluting stents (DES). Inflammation also increases the risk of PCI-related myocardial injury, which is associated with long-term all-cause mortality.
Colchicine is an inexpensive, orally administered, potent anti-inflammatory medication. Recent major trials showed that using low-dose colchicine on top of GDMT reduces cardiovascular events in patients with either chronic coronary syndrome (CCS) or acute Myocardial infarction (MI).
A recent meta-analysis showed that using colchicine in the setting of PCI also reduces cardiovascular events, however, the optimal regimen to subside PCI-associated inflammation is still not clear.
Our aims are
1. Evaluation of colchicine efficacy in protecting against PCI myocardial injury. Our hypothesis is that initiating colchicine 0.5 mg twice daily 72 to 48 hours before planned PCI in CCS patients will decrease PCI-related myocardial injury.
2. Evaluation of colchicine efficacy in preventing PCI-associated inflammation. Our hypothesis is that colchicine will subside post-PCI rise in high sensitive C-Reactive-Protein (hs-CRP).
3. Evaluation of colchicine efficacy in preventing no-reflow phenomenon. Our hypothesis is that colchicine will decrease no reflow phenomenon in CCS patients undergoing PCI.
4. Evaluation of colchicine efficacy in preventing PCI-related (type 4a) MI per the 4th Universal Definition. Our hypothesis is that colchicine will decrease PCI-related (type 4a) MI in CCS patients undergoing PCI.
