This is a study comparing the new class anticoagulants factor XIa to the FDA approved Apixaban. The study is to determine if Milvexian is as effective and safe with preventing clots for patients with A-fib and to determine if Milvexian is better at reducing the chances of bleeding.

This study is enrolling participants with elevated lipoprotein (a) levels, a cholesterol like substance, to test an investigational study medication called olpasiran. Investigational means it has not yet been approved by the US Food and Drug Administration (FDA) for commercial use but has been approved for use in this study. Olpasiran is a subcutaneous injection given every 12 weeks. This study is randomized, which means participants are randomly assigned, like the flip of a coin, to either receive olpasiran or placebo. Placebo looks like the study medication but has no active ingredients. Neither the participants nor the study doctor or study team will know if you are getting study medication or placebo. Participation in this study will last up to 4 1/2 years and include about 14-24 study visits. Study procedures include physical exams, medical history and medication review, electrocardiograms (tracing of the electrical activity of your heart), blood work, questionnaires and medication administration.

This clinical research study is enrolling adults who have high triglycerides (fats in the blood). The study drug, olezarsen, is an investigational drug designed to reduce triglyceride blood levels. If you meet the requirements to participate in this study, you will be randomly assigned to receive either olezarsen or placebo (an inactive substance that contains no drug). During the treatment period, participants will be asked to complete visits every 4 weeks to include a total of 21 visits over approximately 16 months. If eligible, study medication and study visits will be provided free of charge. Compensation is available.

This is an Investigational Device Exemption (IDE) clinical research trial (referred to also as a trial or a research trial) sponsored by AtriCure, Inc (the Sponsor) to learn whether the use of the AtriClip® LAA Exclusion System to close off your left atrial appendage (LAA) during your heart surgery will reduce the risk of stroke. The AtriClip has not been well studied or approved by the FDA for stroke prevention; therefore, this procedure is considered investigational.

This research is being done to assess whether it is safe and effective to stop oral anticoagulation medications (a blood-thinning medication) during prolonged periods of normal heart rhythm in participants with infrequent episodes of atrial fibrillation (AF).

You may qualify for this study if you have a history of atrial fibrillation (AF) and are currently taking an oral anticoagulant (a blood-thinning medication). You will be randomized to one of two groups: Control Group or Study Intervention Group.

If you are randomized to the Control group, you will be asked to stay on your previously prescribed oral anticoagulant. If you are randomized to the Study Intervention group, you will be asked to take the oral anticoagulant for 30 days only if a prolonged episode of AF is detected on an AF-sensing Apple smartwatch you will be provided.

The GORE RELIEF Clinical study is evaluating if anti-clotting medications and/ or closure of Patent foramen ovale (PFO) using the GORE® CARDIOFORM Septal Occluder device in the heart will reduce migraine headaches in adults. The purpose of the study is to investigate whether patients who take a certain type of medication and have a decrease in migraine headaches will also have a decrease in migraine headaches after closure of the PFO, without having to take the medication long-term. It will also look at how safe the study device is (safety) in closing the PFO. The study is randomized and blinded; subjects will have an equal chance of being assigned study medication or placebo pills.

This proposal is to contribute to data registry and sample bank called Pediatrics Biorepository for Cardiology Clinical Research. Samples collected in this study may be used for future research which plan to advance the state of science in the hopes to develop new ways to diagnose and treat children affected with heart conditions.

This study will examine whether a baroreflex activation therapy device (a small pacemakers that are helpful in heart failure) is beneficial for left ventricular assist device (LVAD) patients. For patients who have a baroreflex activation therapy device and LVAD, we assess whether baroreflex activation therapy helps them feel better and have fewer symptoms. We will also look at whether it helps with recovery of their weak heart. Participation in this study will last 6 months and require 3 clinic visits. At each visit, a participant's symptoms will be assessed, they will have pictures of their heart taken to determine function, and bloodwork will be drawn.

Over 2400 people who have sickle cell disease and are between the ages of 15 and 45 have been enrolled into the National Registry (SCDIC-I) of patients with Sickle Cell Disease (SCD). A rich resource of natural history data, the SCDIC-I Registry has longitudinal data collected yearly since 2016 from patient surveys (e.g. self reported pain incidences, sleep, barriers to care, experiences during and after pregnancy), medical record abstraction (e.g. medications, transfusion history, co-morbidities) and laboratory results. The 150 patients (or 1200 among the 8 sites) will be selected from both MUSC adult and pediatric SCD clinics starting at 12 years of age; those not previously enrolled in the SCDIC National Registry will be offered the possibility to enroll in SCDIC-II.
We will look at the following:
1- Compare the effect of new SCD medications – crizanlizumab, voxelotor, and L-glutamine – on clinical outcomes in individuals with SCD.
2 - Identify genetic and genomic predictors of response to crizanlizumab, voxelotor, and L-glutamine
3 - Integrate study data into the CureSCi metadata catalog (MDC) to enhance future cross-study analyses.
