Lactate and Ischemic Preconditioning for Vascular Injury
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether lactate, a natural energy source in the body, can reduce blood vessel damage in individuals at high risk for heart disease. It compares the effectiveness of lactate alone versus its combination with ischemic preconditioning (briefly stopping and starting blood flow) in protecting blood vessels. The trial also examines if combining lactate with ischemic preconditioning is more effective than using the technique alone. Suitable participants are those who have been mostly inactive, are not on heart-affecting medications, and have not recently smoked or used tobacco products. As an Early Phase 1 trial, this research aims to understand how lactate functions in people, offering participants a chance to contribute to groundbreaking heart disease research.
Will I have to stop taking my current medications?
Yes, if you are using medications known to affect cardiovascular function, you will need to stop taking them to participate in this trial.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that administering lactate through an IV is generally safe for people. Studies with adults have reported no major side effects, indicating that the treatment is well-tolerated.
Ischemic preconditioning (IPC) is a method used to protect tissues from damage. Studies indicate that it is commonly used in medical practice and has a good safety record. Specifically, IPC has reduced the risk of complications during heart surgeries.
Research is exploring whether combining lactate with IPC offers optimal protection against injury. Although specific safety data for the combination is not detailed, both treatments alone are considered safe, which is promising for their combined use.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for vascular injury because they explore the potential of intravenous lactate infusion to protect blood vessels from damage in a new way. Unlike traditional methods that often focus on ischemic preconditioning (IPC) alone, this study investigates whether lactate, a naturally occurring substance in the body, can offer similar or enhanced protective effects. The unique aspect is the combination of lactate with IPC, which could potentially boost the body's ability to shield blood vessels from ischemia/reperfusion injury more effectively than IPC alone. This could pave the way for more efficient and potentially quicker ways to manage vascular injuries.
What evidence suggests that this trial's treatments could be effective for reducing vascular injury?
This trial will compare the effects of ischemic preconditioning (IPC) and intravenous lactate infusion on reducing blood vessel damage caused by ischemia-reperfusion injury. Research has shown that IPC can reduce such damage, as demonstrated in studies involving both animals and humans. Early research also suggests that lactate, a natural substance in the body, might protect blood vessels during these injuries by enhancing protein function. Participants in this trial will be randomized to receive either IPC alone or an intravenous lactate infusion alone. Another group will receive a combination of IPC and lactate infusion to determine if this combination offers superior protection compared to either method alone.14567
Are You a Good Fit for This Trial?
Adults at high risk for cardiovascular disease who may have conditions like Arterial Tortuosity Syndrome or Metabolic Syndrome. Participants should not have any health issues that could interfere with the trial, such as severe bleeding disorders or recent heart attacks.Inclusion Criteria

To goal of this Arm is to compare the capacity of ischemic preconditioning (IPC) combined with an intravenous lactate infusion to protect against endothelial ischemia/reperfusion injury to IPC by itself. To achieve this goal, investigators will test the hypothesis that the capacity to protect against endothelial injury will be better when IPC and lactate are combined compared to IPC alone. Participants will be randomized to one of two Interventions. One Intervention will be the IPC intervention by itself. The other intervention will be adding an intravenous lactate infusion together with IPC which is the main focus of the study.
To goal of this Arm is to compare the capacity of ischemic preconditioning (IPC) to protect against endothelial ischemia/reperfusion injury to the capacity of an intravenous lactate infusion to protect against endothelial ischemia/reperfusion injury. To achieve this goal, investigators will test the hypothesis that the capacity for intravenous lactate to reduce endothelial injury will be equivalent to that of IPC. Participants will be randomized to one of two Interventions. One Intervention will be the IPC intervention which is thought to be effective in treating the condition under study. The other intervention is the intravenous lactate intervention, which is the main focus of the study.
