This randomized controlled trial will evaluate whether use of the PulsePoint system increases bystander CPR or defibrillator use compared to standard dispatch procedures in patients who suffer non-traumatic, out-of-hospital cardiac arrest in a public location. Half of all suspected cardiac arrest 9-1-1 calls in a public location will receive PulsePoint alerts (treatment arm). The other half of this eligible patient cohort will receive standard dispatch procedures (control arm). Read Less

This is a Phase 2, multicenter, double-blind, sponsor unblinded, placebo-controlled, single-dose clinical study of CRD-4730 to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of CRD-4730 when administered as single oral doses to participants with Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT). The study will have 2 cohorts in which participants with CPVT will participate in a 3-period, randomized 2-sequence study. Each participant will receive 2 different doses of CRD-4730 and 1 dose of matching placebo, with each study drug administered as a single dose. Read Less

Cardiovascular disease (CVD) represents the leading cause of death worldwide. While medications, such as statins, significantly reduce atherosclerotic CVD (ASCVD) risk by lowering low density lipoprotein levels, they may also have pleiotropic effects on inflammation. The immunomodulatory effects of these medications are relevant to ASCVD risk reduction given that inflammation plays a central role in atherosclerotic plaque formation (atherogenesis) and influences the development of vulnerable plaque morphology. Patients on statins, however, may have residual inflammation contributing to incident ASCVD despite the potent LDL-lowering effects of statins. While new therapies, such as proprotein convertase subtilisin/kexin type 9 (PSCK9) inhibitors, further reduce incident ASCVD and drastically reduce LDL-C below that achieved by statin therapy alone, PCSK9 inhibitors may also have pleiotropic effects on inflammation. Thus, PCSK9 inhibitors may help reduce arterial inflammation to a level closer to that of patients without ASCVD. This study will apply a novel targeted molecular imaging approach, technetium 99m (99mTc)-tilmanocept SPECT/CT, to determine if residual macrophage-specific arterial inflammation is present with statin therapy and the immunomodulatory effects of PSCK9 inhibition. Given the continued high mortality and morbidity attributable to ASCVD, strong imperatives exist to better understand the immunomodulatory effects of lipid lowering therapies and residual inflammatory risk. This understanding, in turn, will inform the development of new ASCVD preventative and treatment strategies as well as elucidate other indications for established therapies. Read Less

Many conditions affecting health are caused by a combination of environment, behaviors, and genes. While individuals can alter some factors in their lives to reduce the chances of developing different diseases (e.g., not smoking cigarettes), the contribution from genetic risk encoded by DNA remains with people throughout their lives. Scientists are still trying to determine the entirety of genetic factors that influence disease, but for some conditions it has been shown that the factors identified thus far can begin to identify people at high to low genetic risk. Looking across the genome, scientists can calculate a cumulative genetic risk score - which can be used to rank genetic risk compared to other worldwide populations. The goal of this study is to determine how genetic risk influences health decisions and other things that can be controlled in life. The first genetic risk score is calculated for coronary heart disease (CAD). CAD ultimately leads to heart attacks, heart failure and sometimes sudden cardiac death and is the main reason heart disease remains as the number one cause of death worldwide. Other researchers have shown that this genetic risk score can be used to identify people with low, intermediate, and high risk for coronary heart disease. It has also been shown that the use of statins (cholesterol lowering drugs) provides greater benefit and protection against heart attack for people with high genetic risk for coronary artery disease. Leveraging the Apple ResearchKit and the ResearchKit linked 23andMe API, customers of 23andMe are able to provide researchers access to their genomic data. Participants will use the ResearchKit app to provide consent, view study information, answer surveys, and contact the study team. Participants will be asked to complete 3 surveys. One before viewing genetic risk scores, one immediately after viewing scores, and one 6 months after viewing scores. Read Less

The University of Texas Health Science Center at San Antonio (UTHSCSA) will serve as the site for the RURAL Study Coordinating Center, led by PI Vasan Ramachandran, MD. The primary function of the Study Coordinating Center (SCC) is to serve as an administrative liaison between all of the RURAL study's cores. The SCC schedules, facilitates, and hosts, all RURAL meetings including preparation for Observational Study Monitoring Board (OSMB) meetings, and maintains direct communication with the study's program officers at NHLBI. The SCC monitors the overall progress of RURAL and keeps all RURAL cores abreast of study updates through meetings, emails, newsletters. It also maintains the official RURAL website and serves as an administrator for investigators seeking to collaborate with RURAL through the submission of Ancillary Studies. The SCC will have no direct interaction with any participants, nor will it have access to identifiable data. Read Less
