Using OFR Software to Observe the Effects of Inclisiran Combined with Statins on the Morphology and Vascular Function of Coronary Vulnerable Plaques

Effects of inclisiran + statins vs. statins on the morphology and vascular function of coronary vulnerable plaques, in order to provide a better treatment and more detailed imaging basis for the treatment of coronary vulnerable plaques.

Study Overview

• Status: Recruiting
• Conditions: Coronary Artery Disease
• Intervention / Treatment: Drug: Rosuvastatin; Drug: Inclisiran sodium

Detailed Description

The identification and treatment of vulnerable coronary plaques is still the focus of coronary heart disease research in recent several years. There are many methods to identify vulnerable plaque, such as NIRS, IVUS, OCT, but these methods have their own advantages and disadvantages, and they can't give the characteristics of diseased plaque completely and clearly. Therefore, if you want to better identify, track and treat vulnerable plaques, you need the comprehensive judgment of multi-modal detection methods, such as the comprehensive data of NIRS, IVUS, OCT, but in this case, there will be more and more invasive operations for patients, and the operation cost is high and time-consuming. OFR analysis software can quickly analyze the morphological and functional parameters of diseased vascular plaques based on OCT data, overcome the shortcomings of poor penetration of OCT and inability to observe the overall lesion contour, and can immediately give the morphological and functional parameters of diseased plaques, combining the data results of OCT, IVUS and FFR multimodal detection methods.

Statins have the effect of inducing regression and transforming coronary plaques into stability, but there are also some problems in the process of statin treatment. For example, for some patients with coronary heart disease, even the maximum tolerated dose of statins can not achieve the target goal of LDL-Cl; The side effects of statins, such as liver damage, muscle pain and blood sugar fluctuation, reduce the compliance of some patients. In recent years, the lipid-lowering effect of non-statins and the effect of stabilizing and reversing plaques have also attracted much attention, especially PCSK9 monoclonal antibody, such as, GLAGOV study, HUYGENS study, ALTAIR study and PACMAN-AMI study, compared with statins, they can reduce the plaques volume and stabilize the plaques morphology.

Inclisiran is the first siRNA drug in cardiovascular field. As a new generation of drugs acting on PCSK9, the current clinical research (ORION research series 1, 3, 8, 9, 10, 11) shows good lipid-lowering efficacy and safety tolerance. On the basis of statin therapy, LDL-C46%-55% is further reduced, which is more durable than monoclonal antibody, and the drug effect can last for half a year once used, and it has good safety and tolerance (except for the slight reaction of injection, there are almost no other side effects). So far, the research of Inclisiran mainly focuses on the safety and efficacy of lipid-lowering and the observation of clinical events, and the research on vulnerable plaque is very scarce. In this study, OFR analysis software will be used to observe whether Inclisiran combined with statin is superior to statin standard treatment on the vulnerable plaques, and it is expected to provide more superior clinical treatment scheme and more accurate imaging basis for identifying and treating vulnerable coronary plaques.
