Feasibilty study of biochemical urine analysis of adherence to high intensity statin therapy in outpatients with coronary artery disease
Background: Early detection and treatment of coronary artery disease (CAD) can help curb the high incidence of cardiovascular disease, which is the leading cause of death worldwide. Today, we have sophisticated imaging techniques available to diagnose CAD, including cardiovascular magnetic resonance (CMR). CMR is able to detect relevant myocardial ischemia and guide treatment options. Therefore, it is recommended by the current guidelines for patients at intermediate risk. In clinical practice, we often encounter two main issues: first, because of their availability and increasing uncertainty in the population, imaging techniques are increasingly used, even in patients with a low pretest probability for the presence of CAD. Second, the diagnostic accuracy of the techniques is not perfect, and false-negative stress CMR perfusion studies are an important limitation of the method, especially in patients with advanced CAD and balanced ischemia. In addition, the standard method with pharmacologic testing carries an inherent risk. Aim: The aim of our project is to review the clinical pretest probability to reduce unnecessary imaging studies and to evaluate the improvement of diagnostic accuracy of CMR stress testing by adding exercise test and reviewing biomarkers, which could reduce the number of false-negative results, especially in patients with balanced ischemia, who usually suffer from severe CAD. Methodology: This is a prospective, randomized, two-arm, controlled, monocentric, national study performed in collaboration by two centers (Solothurner Spitäler AG and CRIB). Included are consecutive patients with suspected inducible myocardial ischemia who are examined by CMR at the Kantonsspital Olten and during the course also at the Bürgerspital Solothurn. Since all patients from the Kanton Solothurn are referred to us for CMR diagnosis, this represents an ideal referral pattern of unselected patients with a wide range of pretest probability for myocardial ischemia (interquartile range of pretest probability 20-60%). Patients able to exercise will randomized to either standard CMR stress protocol with regadenoson or to the combined CMR stress protocol, which includes additional exercise testing and measurement of hs-cTn, a biomarker for detecting myocardial damage. Patients with positive CMR results will be received to coronary angiogram. Potential Significance: This project has the potential to reduce the residual risk and thereby reduce cardiovascular mortality in patients with false-negative test result, especially those with balanced ischemia or inadequate response to vasodilatation drugs. In addition, the investigator will be able to make a statement about the additional use of biomarkers for the diagnosis of CAD in patients with stable condition. Thereby, the integrated use of biomarkers may improve the diagnostic accuracy and this might prevent unnecessary further strategies, which will reduce high-cost in health care systems. Furthermore, the investigator hopse for better patient selection in order to avoid unnecessary examinations in the future.

Cardiovascular diseases (CVD) and neoplasms are the main causes of death in Brazilian women. Coronary artery disease (CAD) and stroke were responsible for approximately 54% of deaths from CVD in this population. In Brazil, cancers were the second cause of death and in 2017 were responsible for 58% of deaths in women. CVD and cancer share some risk factors, and control of these factors is associated with a significant reduction in cancer incidence. These two causes of death, although apparently disparate, share similar lifestyles and health risk factors, suggesting some common pathways and basic molecular networks. In women, the presence of estrogen has protective effects against atherosclerosis and, with the decline in hormone production at menopause, the incidence and prevalence of CAD increase substantially. Although the estrogen pathway is supposed to have a central effect on this increased risk, it is still debated whether other non-estrogenic mechanisms are related, since hormone replacement alone does not reduce cardiovascular events. Sirtuins and soluble advanced glycation product receptors (sRAGE) are associated with increased vascular protection, while the role of apoptosis inhibiting proteins, a pathway linked to increased cancer incidence, is still unclear in the context of atherosclerosis. Resveratrol is a key activator of sirtuins and potentially modulates these metabolic pathways, reducing cardiovascular risk. This randomized, double-blind, parallel, placebo-controlled clinical trial will be carried out in 80 postmenopausal women with CAD to analyze the effect of treatment with resveratrol on serum concentration and gene expression of sirtuins-1 -3, in the serum sRAGE concentration and in the gene expression of apoptosis inhibitory proteins.
This study is a prospective, multicenter study in the real practice to validate the diagnostic performances and clinical impact of coronary angiography & intravascular ultrasound (IVUS)-based models developed by machine learning (ML).
In this prospective, single-arm study, we will look at the initiation, participation, sustained engagement, and safety of 100 adult subjects (ages 45 years or older) with recent (within the past 60 days) clinician referral to CR who are offered CTR via the RecoveryPlus platform. We want to understand the effectiveness of the RecoveryPlus platform in engaging participants in CR while remaining a safe alternative for the delivery of evidence-based CR content. The primary hypothesis of this study is that the RecoveryPlus CTR platform and patient-facing mobile application provide a safe alternative to traditional in-person CR, and demonstrate a high rate of initiation, participation, and engagement in CR exercise programming than traditional modes of CR delivery, as documented in the literature. Current in-person and non-personalized CR programming lacks RecoveryPlus' convenient remote access, easy-to-use digital tools to support independent, autonomous exercise, and a platform to facilitate engagement and feedback between patients and EPs.
Coronary revascularization interventions such as coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) are the standard of surgical treatment of patients with myocardial ischemia. However, up to 30% of patients experience complications of varying degrees within 12 months after the revascularization, or need for second intervention. Thus, it is necessary to search for additional approaches to the postoperative treatment of patients in order to improve the long-term results of revascularization treatment. Substances of natural origin with an anti-atherosclerotic effect have a good potential. These substances, as dietary supplements, can be taken by patients for a long time in conjunction with other prescribed medicines and treatments. Another valuable direction of investigations is the search for predictors of long-term cardiovascular complications after revascularization, which can be markers of inflammation and heteroplasmy levels of the patient's mitochondrial genome. The purpose of this study is to determine whether the intake of dietary supplement Allicor at a daily dose of 300 mg affects the frequency of long-term postoperative cardiovascular complications and re-intervention in patients after revascularization operations on the coronary arteries. The second goal is assessing the relationship between the grade monocytes inflammatory response and the level of heteroplasmy of the mitochondrial genome of blood leukocytes with the frequency of cardiovascular complications and re-interventions.
In patients with coronary heart disease who were treated with PCSK9 inhibitor evolocumab for intensive lipid-lowering therapy, the changes of retinal microvessels were measured with OCTA (Optical Coherence Tomography Angiography)before and after the treatment. The specific indicators included retinal microvessel diameter, macular areaļ¼optic disc vascular density and FAZ(Foveal Avascular Zone)area, etc., to clarify the effect of evolocumab on retinal microvessels after intensive lipid-lowering therapy.
