Atheroscleroses

Narrowing of the carotid artery due to atherosclerosis with an unstable plaque can cause a stroke. Patients with carotid artery disease who have had a TIA or minor stroke and are at high risk of another stroke are often treated with surgery or stenting to remove the plaque. For lower-risk patients, medication alone is the better option, as surgery also carries risks. A new decision method, based on MRI detection of unstable plaques (IMPROVE), can better assess stroke risk and help determine which patients do or do not need surgery. We are investigating whether this method is at least as effective as the standard approach, which mainly considers the degree of narrowing. We expect that this new method will help reduce strokes and lower healthcare costs. Patients will be followed for several years to compare which method is better for health and costs.

The goal of this clinical trial is to learn if Yiyang Huoluo Decoction (a custom Chinese herbal medicine) works safely and effectively to treat coronary heart disease with atherosclerosis in older adults. It also aims to find out how this herbal treatment may affect blood vessel health and repair at a cellular level. The main questions it aims to answer are: * Does adding Yiyang Huoluo Decoction to standard Western medical care improve symptoms and heart-related health in older adults with coronary heart disease and atherosclerosis? * Is Yiyang Huoluo Decoction safe for older adults to take alongside their regular heart medications? * How does this herbal treatment affect the damaged blood vessels in study participants? Researchers will compare two groups of participants to see if the combined treatment works better than standard care alone. Who can take part: Older adults diagnosed with coronary heart disease and atherosclerosis who meet the study's health and eligibility rules. What participants will do: * Be split randomly into two groups of 15 people each: one group gets standard Western heart medicine only, and the other gets standard Western heart medicine plus Yiyang Huoluo Decoction (herbal granules) * Complete the 12-week decoction treatment plan as directed by the research team * Attend scheduled study visits for health checks, blood tests, heart and blood vessel scans (such as carotid ultrasound and coronary CTA), and symptom reviews * Provide two small blood samples for research testing (samples will be destroyed after study testing is finished) * Report any side effects, discomfort, or changes in health to the research team right away All personal health information collected for this study will be kept private and confidential. Participation is completely voluntary, and participants may quit the study at any time for any reason without losing access to regular medical care.

Aim. To study the effect of different intensities of statin therapy on androgen status and erectile function in men aged 40-65 years with high and very high cardiovascular risk. Additionally, to assess the association between sex hormone levels, erectile function parameters, and traditional cardiovascular risk factors, arterial stiffness, and endothelial function in this patient category. Material and methods. It is planned to conduct a prospective randomized controlled trial, including 150 male patients aged 40-65 years, undergoing routine preventive examinations in the clinic of Moscow State University, having a high and very high risk of cardiovascular diseases and meeting the inclusion criteria. Group Pit (n=75) will receive pitavastatin at a starting dose of 1 mg/day. Group Ros (n=75) will receive rosuvastatin 20 mg/day. After 3 months, the biochemical parameters will be monitored, and dose titration of pitavastatin to 2-4 mg/day and/or rosuvastatin to 40 mg/day will be performed if necessary. Patient recruitment to the study will occur over 9 months at a single research center. Patients will be monitored with an objective assessment of erectile function parameters, blood analysis (including androgen status), central arteries stiffness, and endothelial function for 6 months from the moment of activation. Follow-up visits are scheduled at 1, 3 and 6 months. Results. The expected result of testing the research hypothesis is that statin therapy will not have a negative effect on androgen status and erectile function in men. Intensive statin therapy will have a greater positive effect on endothelial function, which may lead to an improvement in men's erectile function. Conclusion. The study was planned under the assumption that statin therapy would not have a negative effect on androgen status and erectile function in men aged 40-65 years. It is also suggested that the positive effect of statins on endothelial function and vascular stiffness may lead to an improvement in erectile function among men with high and very high cardiovascular risk. If the hypothesis is confirmed, the results obtained will help improve statin treatment adherence in male patients and, as a result, increase the effectiveness of prevention of cardiovascular events.

The goal of this clinical trial is to find out whether treating vulnerable plaques in the coronary arteries with a drug-coated balloon can make them less dangerous than using standard medication alone. The study includes adults with acute coronary syndrome (a type of heart problem caused by reduced blood flow in the coronary arteries). The main questions the study aims to answer are: * Does the drug-coated balloon reduce the amount of fat inside the plaque more than medication alone? * Is this treatment safe for patients? Participants will: * Undergo imaging of their coronary arteries during their planned heart procedure (PCI) * Be randomly assigned to receive either a drug-coated balloon treatment or no extra treatment * Undergo a heart scan (CT scan of the coronary arteries) within 2 weeks and again around 9 months after the procedure. * Undergo a second heart catherization 9 months later to examine changes in the plaque.
