NCT ID: NCT03847753 Active, not recruiting - Hypertension Clinical Trials

Exploring the Comorbidity Between Mental Disorders and General Medical Conditions

Start date: January 1, 2000
Study type: Observational [Patient Registry]

Mental disorders have been shown to be associated with a number of general medical conditions (also referred to as somatic or physical conditions). The investigators aim to undertake a comprehensive study of comorbidity among those with treated mental disorders, by using high-quality Danish registers to provide age- and sex-specific pairwise estimates between the ten groups of mental disorders and nine groups of general medical conditions. The investigators will examine the association between all 90 possible pairs of prior mental disorders and later GMC categories using the Danish national registers. Depending on whether individuals are diagnosed with a specific mental disorder, the investigators will estimate the risk of receiving a later diagnosis within a specific GMC category, between the start of follow-up (January 1, 2000) or at the earliest age at which a person might develop the mental disorder, whichever comes later. Follow-up will be terminated at onset of the GMC, death, emigration from Denmark, or December 31, 2016, whichever came first. Additionally for dyslipidemia, follow-up will be ended if a diagnosis of ischemic heart disease was received. A "wash-out" period will be employed in the five years before follow-up started (1995-1999), to identify and exclude prevalent cases from the analysis. Individuals with the GMC of interest before the observation period will be considered prevalent cases and excluded from the analyses (i.e. prevalent cases were "washed-out"). When estimating the risk of a specific GMC, the investigators will consider all individuals to be exposed or unexposed to the each mental disorder depending on whether a diagnosis is received before the end of follow-up. Persons will be considered unexposed to a mental disorder until the date of the first diagnosis, and exposed thereafter.

Risk EValuation And Its Impact on ClinicAL Decision Making and Outcomes in Heart Failure

Start date: April 1, 2019
Phase: N/A
Study type: Interventional

Heart failure is a complex and heterogenous disease with mortality and morbidity that equals more cancers. Numerous studies have examined the ability to improve prognostication from heart failure, ranging from basic statistical methodologies to machine learning, with impressive improvements in both predictive indices. However, no study to date has examined, in a randomized fashion, the impact of providing prognostic information on provider behavior and downstream clinical outcomes. It is for this reason that the investigators plan to perform the Risk EValuation And Its Impact on ClinicAL Decision Making and Outcomes in Heart Failure (REVeAL-HF) Trial within the Yale New Haven Health System. REVeAL-HF is a randomized, single-blind intervention trial that is testing the clinical impact of providing prognostic information to the provider on heart failure outcomes in the inpatient settings. The study hypothesis is that electronic alerting about prognostic information on heart failure patients along with links to guidelines will lead to reductions in all-cause mortality and 30-day HF hospitalizations via improved use of guideline directed medical therapy and more adequate decongestion.

NCT ID: NCT03845309 Not yet recruiting - Clinical trials for Chronic Heart Failure

Nutritional Interventions in Chronic Heart Failure

Start date: February 20, 2019
Phase: N/A
Study type: Interventional

This study recruited patients diagnosed with heart failure by cardiologists and cardiac outpatients whose cardiac functions were graded from 1 to 4 according to the New York Heart Association as the study participants. The participants were provided active nutrition intervention including diet optimization,specific recommendations and nutritional supplement prescriptions in cases in which nutritional goals were not reached.In addition, this study offered advice by referencing lifestyle change advice provided by the American Heart Association for patients with heart failure. The Mini Nutritional Assessment Short-Form was used to assess malnutrition indicator values. The participant water, nutrient (i.e., carbohydrates, protein, and fat), and calorie intake data were collected using their recollection of their dietary intake and food intake frequency over a 24-hour dietary recall. The amount of fluid and sodium administered was provided according to the cardiac function grades indicated by the New York Heart Association.In addition, dietary assessments and nutritional advice were offered on the basis of the patients' conditions (i.e., age, activity, and comorbidity). Finally, instrumental activities of daily living, EQ-5D (an instrument for measuring quality of life), grip performance, and 6-minute walk test data were utilized to analyze the changes in the participants before and after intervention, identifying the correlation between using nutrition education as an intervention measure and improvement in the participants' nutritional status, quality of life, and self-care behavior.

Randomized Evaluation and Verification of Ventricular Enhancement

Start date: March 15, 2019
Phase: N/A
Study type: Interventional

A prospective, multi-center, dual-arm randomized controlled study comparing treatment of ischemic cardiomyopathy induced heart failure with the Revivent TC System plus Guideline Directed Medical Therapy (GDMT) compared to GDMT alone.

NCT ID: NCT03843242 Not yet recruiting - Heart Failure Clinical Trials

Evaluation of Ventricular Pacing Suppression Algorithms in Dual Chamber Pacemaker

Start date: May 2019
Phase: N/A
Study type: Interventional

The recent study using IRSplus and VpS algorithm from Biotronik pacemaker showed the significant reduction in ventricular pacing to less than 3%. The purpose of this study is to evaluate the efficacy of IRSplus and VpS algorithm in reducing ventricular pacing compared with conventional DDD pacing with a fixed AV delay.

A Single Center Study in Healthy Volunteers to Assess the Pharmacokinetics of AZD9977 When Administered Alone and With Itraconazole

Start date: February 7, 2019
Phase: Phase 1
Study type: Interventional

This is an open-label, non-randomized, fixed sequence study conducted at a single study center with primary aim to assess the pharmacokinetics (PK) of AZD9977 in healthy volunteers when administered alone and in combination with multiple doses of itraconazole.

NCT ID: NCT03843021 Not yet recruiting - Heart Failure Clinical Trials

Ventricular Assist Device (VAD) Infection Prevention Survey

Start date: April 2019
Study type: Observational

Annually, more than 250,000 patients in the U.S. with end-stage heart failure stand to benefit from ventricular assist device (VAD) therapy. 60% of patients develop a healthcare-associated infection (HAI) within 90-days of implantation. The investigators long term goal is to develop and subsequently promote wide-scale adoption of evidence-based HAI prevention practices following durable VAD implantation. This will be done by addressing the following aims: Aim 1. Identify determinants of center-level variability in HAI rates. Aim 2. Develop a comprehensive understanding of barriers and facilitators for achieving low center HAI rates. Aim 3. Develop, iteratively enhance, and disseminate a best practices toolkit for preventing HAIs that accommodates various center contexts. The investigators will use a focused survey of U.S. VAD centers to identify determinants of center variation in 90-day HAI rates: - Process Factors (e.g., intranasal mupirocin), - Provider Factors (e.g., surgeon technique), - Device Factors (e.g., centrifugal vs. axial), - Center Factors (e.g., provider communication). Understanding the barriers and facilitators within individual centers for maximizing adoption of prevention measures would serve as the foundation for targeted improvement strategies. Without this knowledge, evidence-based, action-oriented recommendations will have limited local adoption and ultimately effectiveness in preventing HAIs after VAD implantation.
