LDL Cholesterol

This clinical trial will study why some people have a larger drop in low-density lipoprotein cholesterol (LDL-C), known as "bad cholesterol," after starting ezetimibe. Ezetimibe is a medicine used to lower cholesterol when current treatment is not enough. Adults aged 18 to 75 years who need additional cholesterol treatment will take ezetimibe, either alone or added to their usual stable medication. Researchers will examine whether diet, salt intake, physical activity, and personal health factors influence how much LDL-C levels fall after treatment. Participants will have blood tests before and after starting ezetimibe, complete diet and activity questionnaires, and provide a 24-hour urine sample. The goal is to help doctors better understand who benefits most from ezetimibe and improve personalized cholesterol treatment.

This study aims to evaluate the effectiveness of NeoMayor, a mobile health (mHealth) intervention designed to improve cardiovascular health among older adults at elevated cardiovascular risk in Chile. NeoMayor is a smartphone-based application that provides personalized guidance on physical activity, diet, sleep, and mental well-being through a multidomain lifestyle approach. This multicenter randomized controlled trial will enroll community-dwelling older adults aged 55 to 75 years recruited from primary healthcare centers in urban and rural settings. Participants will be randomized in a 2:1 ratio to either the NeoMayor intervention or a control group receiving standard health information and usual care. The intervention duration will be four months. The primary objective is to determine whether the NeoMayor intervention improves cardiovascular health as measured by the Life's Essential 8 Cardiovascular Health Index. Secondary objectives include evaluating changes in cognitive performance, depressive symptoms, anxiety symptoms, quality of life and physical performance outcomes. The study will also assess feasibility and adherence to digital intervention.

The purpose of this study is to evaluate the effects of kefir on gastrointestinal health, sleep quality, and biochemical parameters in adults who have sleep problems. Further measurements of cognitive function, arterial stiffness and blood pressure will also be assessed. The following questions will be addressed during the study: 1. What effect does repeated ingestion of kefir have on the gut microbiome and can this positively influence sleep performance (quality and duration) in adults with sleep problems? 2. Does repeated ingestion of kefir impact LDL, triacyglycerols and non-HDLc in adults with sleep problems? 3. What effect does repeated ingestion of kefir have on cognitive function and mood? 4. What effect does repeated ingestion of kefir have on vascular function, inflammation and markers of immunity in adults with sleep problems? In a randomised, crossover design study, participants will consume 250 ml of kefir (original flavour) or milk for 4 weeks with a 4-week washout.

This multicenter randomized trial is designed to assess the efficacy of lipid-lowering therapy in patients undergoing percutaneous coronary intervention, comparing an Apolipoprotein B-targeted approach with a Low-Density Lipoprotein Cholesterol (LDL-C)-targeted approach. The primary outcomes are to evaluate the proportion of patients achieving lipid-lowering treatment goals at the 1-year follow-up between the two treatment strategies: Apolipoprotein B-based therapy versus LDL-C-based therapy.

Intensive Lipid-Lowering Therapy guided by a cloud-based Software System (CLIMEDO GmbH) improves (European Society of Cardiolofgy/European Atherosclerosis Society) ESC/EAS-guideline recommended LDL-cholesterol target attainment and adherence in patients with ST-Elevation Myocardial (STEMI) and Non-ST-Elevation Myocardial Infarctions (NSTEMI).

To determine whether treating to an LDL-C target of 25 to \<70 mg/dL is superior to an LDL-C target of 70 to \<100 mg/dL with respect to major cardiovascular events (cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization) in patients aged ≥75 years with atherosclerotic cardiovascular disease (ASCVD). To determine whether treating to an LDL-C target of 25 to \<70 mg/dL is non-inferior to an LDL-C target of 70 to \<100 mg/dL with respect to major safety events (hemorrhagic stroke, new-onset diabetes, muscle-related events, neurocognitive adverse events, new or recurrent cancer, cataract, or hepatic disorder \[Alanine aminotransferase (ALT)/Aspartate aminotransferase (AST) \>3× ULN, or total bilirubin \>2× ULN\]) in patients aged ≥75 years with ASCVD.
