The purpose of the study is to test for validity and reliability in the revised Post Event Cardiovascular Risk Perception Survey (PE-CRPS) among individuals who are diagnosed with heart disease (post heart event).

The purpose of the study is to test for validity and reliability in the revised Post EventCardiovascular Risk Perception Survey (PE-CRPS) among individuals who are diagnosed with heart disease (post heart event). The researchers plan to learn more about how individuals perceive their chance of developing certain cardiac risk factors after they have had a heart event such as after having a heart attack, or having cardiac surgery. If you join the study you will help us learn about: 1) what patients perceive their chance of developing certain cardiac risk factors, 2) how to structure cardiac rehab programs.

This clinical study is a prospective, multicenter, single-arm clinical evaluation of the Multi-Electrode Radiofrequency (RF) Balloon catheter. The purpose of this study is to evaluate the overall safety and effectiveness of the Multi-Electrode RF Balloon catheter, in conjunction with the Multi-Electrode Circular Diagnostic catheter and Multi-Channel RF Generator, for the treatment of drug refractory Paroxysmal Atrial Fibrillation (PAF). Embedded within the Main Study will be a Neurological Assessment Evaluable (NAE) subset and a Cardiac Computed Tomography (CT) or Magnetic Resonance Angiogram (MRA) image (CT/MRA) subset with consecutive enrollment and a prospective design. The same subject can participate in both the NAE and cardiac CT/MRA subsets. The study will enroll subjects with drug refractory, symptomatic PAF who are candidates for catheter ablation. The first 1-3 subjects for each ablating physician will be considered roll-in subjects to verify consistent workflow for study device components and to minimize any learning curve effects. The roll-in subjects will not be included in the NAE subset, cardiac CT/MRA subset, or in the primary endpoint analyses. The roll-in phase will include a maximum of 240 subjects and the main study phase will include a maximum of 400 evaluable subjects. Subjects will be evaluated prior to the procedure, prior to discharge, and post procedure at 7 days (7-14 days), 1 month (23-37 days), 3 months (76- 104 days), 6 months (150-210 days), and 12 months (315-405 days) unless otherwise specified in the protocol.

This is a clinical study sponsored by Amgen Inc. It is a study being done for patients that are at high risk for experiencing a cardiovascular event (like a heart attack or stroke). Elevated cholesterol, in particular low-density lipoprotein cholesterol (LDL-C), can lead to obstructing fatty deposits in blood vessels that can greatly increase the risk of developing cardiovascular disease or experiencing a cardiovascular event. The purpose of this research study is to assess whether lowering of cholesterol blood level can reduce your risk for major cardiovascular events (for example, heart attack or stroke) when evolocumab is taken in addition to current medical therapy as directed by a doctor, which may include a medication for the treatment of abnormal cholesterol blood levels called statins.

Your baby will be monitored throughout the study for respiratory illnesses.

Protocol #: 19-1403

Location: Childrens Hospital Colorado

This is a study for patients that have a heart condition in which the upper chambers of your heart beat irregularly. This condition, also known as atrial fibrillation, can cause blood clots to form in an area of your heart called the left atrial appendage (LAA). Everyone has a LAA, which is like a pouch on the top of your heart, and it developed along with the other parts of the heart before birth. If a clot forms here, it can increase your chances of having a stroke or other related problems. Because you have atrial fibrillation, it is believed that if the LAA is closed, then blood clots might not be able to form in that area. The current standard of care to prevent stroke in patients with atrial fibrillation is long-term oral anticoagulation (OAC) therapy (blood thinner medication) or, in appropriately selected patients, implant of the commercial WATCHMANTM device followed by short-term OAC therapy.

The SURPOINT COA study is a prospective, multicenter, non-randomized post-market clinical evaluation of the VISITAG SURPOINT™ Module with EPU when used with the STSF/ST catheters in treating subjects with symptomatic PAF who have failed at least one antiarrhythmic drug. A total of 330 subjects will be enrolled at up to 45 sites. Two hundred eighty (280) enrolled subjects will be treated using the STSF catheter with EPU and fifty (50) subjects will be treated with ST catheter. Prior to enrollment, a few sites will be selected to only enroll subjects who will be treated with the ST catheter and the remaining sites will only enroll subjects who will be treated with the STSF catheter. Effectiveness and safety endpoints have been defined, and will be compared to predetermined performance goals. Subjects who sign the SURPOINT COA informed consent are considered enrolled in the study. Enrolled subjects who satisfy all eligibility criteria will then undergo the ablation procedure with the catheter and VISITAG SURPOINT™ Module. After the study ablation procedure, subjects will enter a 3-Month blanking period (Day 0-90). After the Blanking Period, subjects will enter the Evaluation Period (Days 91-365). Subjects having AF recurrence and/or receiving therapeutic interventions during the evaluation period will be considered effectiveness failures (refer to Section 4.1.1 for all effectiveness failure modes). All subjects will undergo follow up visits at defined intervals (refer to Table 5-1 Schedule of Treatments and Evaluations). Subjects complete the SURPOINT COA study after the 12-month follow up visit.

Protocol #: 18-2765

Location: University of Colorado Hospital

About 15,000 people will take part in this study. Half will get inclisiran injections and half will get dummy placebo) injections. A placebo is a substance that looks like a drug, but has no drug in it. This form will refer to both inclisiran and placebo as “study drug.” Which study drug you get is decided by chance and you will not know which study drug you are given. Joining the study involves 3 clinic visits in the first 5 months and then a visit every 6- months. At each visit a trained researcher will ask some questions about your health, take a blood sample, and give you an injection into your abdomen (tummy). It is expected that about 1 in 20 people administered inclisiran may notice some redness or soreness where the injection is given, but no other side effects have been found. However, at this stage, scientists cannot rule out the possibility of other side effects. You are asked to stay in the study for about 5 years.

The purpose of this study is to learn more about where the fat tissue in your body originates. For many years it has been thought that all fat cells come from cells that are from the fat tissue itself, but now we know it is possible that some fat cells may originally come from the bone marrow. Understanding the origin of fat cells is important because it may help to determine the health of fat cells. You are being asked to be in this research study because you are a person over the age of 18 who has had a hematopoietic stem cell transplant or has chronic phase chronic myeloid leukemia (CML).

To understand if some fat cells (adipocytes) may originally come from cells in the bone marrow. Understanding the origin of fat cells is important because it may help to determine the health of fat cells and why fat that is stored in some places of your body is more unhealthy than other fat.
