NCT ID: NCT05195931 Terminated - Clinical trials for Heart Failure, Systolic

Cardiac Output in Heart Failure Patients With Mechanical Pumps

Start date: June 8, 2021
Phase:
Study type: Observational

This study will be looking at how cardiovascular hemodynamics, including cardiac output and flow through a left ventricular assist device (LVADs), change in response to alterations in preload, afterload, and contractility, and also during exercise, in humans with heart failure who are supported by LVADs.

NCT ID: NCT04264182 Terminated - Clinical trials for Heart Failure, Systolic

STandardized Ultra-conservative Or Physician-directed ICD Programming for Continuous Flow LVAD Support

Start date: February 3, 2020
Phase: N/A
Study type: Interventional

This study will evaluate the utilization of an ultra-conservative programming strategy to reduce shocks for ventricular arrhythmias (VA) among patients with heart failure, an implantable cardioverter-defibrillator (ICD) and continuous flow (CF) left ventricular assist device (LVAD). Patients on LVAD support demonstrate unique hemodynamic tolerability of VA, and the role for ICDs among patients with newer generation CF LVADs remains less clear than the older generation devices. Prior studies have explored extended detection ICD programming to reduce unecessary or potentially avoidable shocks to patients. However, no prospective randomized study to-date has evaluated such programming strategies in the CF LVAD patient population. The study hypothesis is that ultra-conservative (UC) ICD programming will result in a reduction of shocks and an improvement in quality of life without increasing hospitalizations, syncope or death among patients on CF LVAD support, and the primary design is a 1:1 randomization between UC programming over standard, physician discretion programming.

NCT ID: NCT04095416 Terminated - Clinical trials for Heart Failure; With Decompensation

Compression Wraps as Adjuvant Therapy in Management of Acute Systolic Heart Failure

CATAS-HF
Start date: August 15, 2019
Phase: N/A
Study type: Interventional

There will be two populations in this study: control group, and intervention group. These groups will undergo propensity matching to account for confounders and minimize selection bias. 120 patients will be enrolled, 60 to each population. The objective of this study is: assess the utility of lower extremity compression wraps as adjuvant therapy in inpatient management of acute systolic heart failure The control group will consist of patients admitted to I5 Cardiology for management of acute systolic heart failure with intravenous diuresis and standard medical therapy, meeting inclusion criteria. Information will be gathered through observational prospective data analysis from Epic EMR, and will include daily diuretic type and dose required, daily urine output, daily creatinine, total days of admission, daily and pre-discharge weight, admission BNP, and pre-discharge BNP. The intervention group will consist of patients admitted to I5 Cardiology meeting inclusion criteria and being managed with standard medical therapy. This group will receive additional therapy using bilateral lower extremity compression wraps applied by nursing staff per pre-set protocol, and will receive education on the use of compression wraps. Patients will be instructed to wear the compression wraps for the entirety of the time they are undergoing intravenous diuresis, with pauses in care as needed for hygiene and symptom relief purposes. During the time of compression wrap application, the following data will be collected: urine output, daily weights, daily creatinine, daily and total dose and type of intravenous diuretic used. Prior to discharge, a BNP will be obtained. Endpoints (including percentage of weight reduction, total urine output achieved with diuresis, total dose requirement and type of intravenous diuresis, total days of intravenous diuresis, days to discharge, discharge BNP, and percent reduction from admission BNP) will then be compared to assess the utility of adding lower extremity compression wraps to inpatient management of acute systolic heart failure.

NCT ID: NCT03991000 Terminated - Clinical trials for Cardiovascular Diseases

iCHF-2
Start date: February 28, 2019
Phase: Phase 3
Study type: Interventional

It is now recognized that iron deficiency in cardiovascular disease contributes to impaired clinical outcome.

NCT ID: NCT03936608 Terminated - Clinical trials for Cardiac Resynchronization Therapy

ECG for Programming in CRT

EPIC
Start date: April 22, 2019
Phase: N/A
Study type: Interventional

Patients with heart failure and left bundle branch block benefit from Cardiac Resynchronization Therapy (CRT) that delivers pacing from right ventricle (RV) and left ventricle (LV) synchronously, resulting in electrical ventricular resynchrony followed by revere structural cardiac remodeling and thereby reduced heart failure symptoms, hospitalizations and death. It is not known if programming an individually optimized RV-LV pacing offset to maximize electrical resynchrony can improve benefit from CRT. The proposed study is a randomized controlled trial in patients undergoing implant of a CRT pacemaker/defibrillator device for clinical indications to evaluate benefit of RV-LV offset programming using electrocardiogram (ECG) vs. standard nominal CRT programming without RV-LV offset. Patients receiving CRT devices will be randomized to either (A) active intervention of programming RV-LV pacing offset to optimize ECG or to (B) active control of nominally programming CRT device without RV- LV offset. The patients will be followed to evaluate change in echocardiogram, quality of life, functional evaluation and a blood marker for heart failure.

NCT ID: NCT03492788 Terminated - Clinical trials for Heart Failure, Systolic

Optimizing CRT With ECGI

optCRT
Start date: December 28, 2017
Phase: N/A
Study type: Interventional

CRT is delivered from two electrodes on opposite sides of the heart [right (RV) and left ventricle (LV)] delivering stimulation for more efficient heart beats. There is flexibility in the sequence and temporal staggering of the stimulation from these two electrodes with a different optimum for different patients. However, standard techniques to figure out the optimal stimulation strategy like standard 12-lead surface electrical recording (ECG) or routine ultrasound have failed. The investigators have developed ECG imaging (ECGI) with 250 electrode surface recording combined with CT scan to reconstruct high resolution 4-dimensional panoramic electrical maps of the heart. The study seeks to enroll 56 patients undergoing CRT in a clinical trail to evaluate short and long term impact of using ECGI for optimal programming of CRT.

NCT ID: NCT03425422 Terminated - Heart Failure Clinical Trials

ANTHEM-HFrEF Pivotal Study

Start date: May 1, 2018
Phase: N/A
Study type: Interventional

A multi-center randomized controlled clinical trial to evaluate Autonomic Regulation Therapy with the VITARIA system in patients with symptomatic heart failure and reduced ejection fraction.

NCT ID: NCT03089502 Terminated - Breast Cancer Clinical Trials

Efficacy of Cardio-Oncology Rehabilitation Exercise for Women With Breast Cancer and Treatment Related Cardiotoxicity

CORE
Start date: April 1, 2018
Phase: N/A
Study type: Interventional

Breast cancer is the leading cause of cancer among Canadian women with nearly 26,000 new cases diagnosed each year. Fortunately, advancements in diagnostic tools and curative treatments have significantly improved overall survival. However, the development of cardiac toxicity (including asymptomatic and symptomatic heart failure) associated with use of anthracycline containing chemotherapy and targeted therapies including trastuzumab limits improvements in survival for women with breast cancer. Cardiac toxicity is a life threatening complication that leads to reduced physical functioning and quality of life. The increased risk is associated with shared risk factors among cancer and heart failure and the direct influence of cancer therapy on the cardiovascular system. Cardiac rehabilitation (CR) (including exercise training and education/counselling) has been shown to improve health outcomes, reduce heart failure related hospitalizations and modestly improve mortality among individuals with non-treatment related heart failure and may benefit women with breast cancer and treatment related cardiac toxicity (BC-CT). Therefore, this single centre, randomized control trial aims to determine if participation in an exercise based CR program can improve cardiorespiratory fitness, cardiovascular function/structure and health, and quality of life among women with BC-CT.

NCT ID: NCT01935622 Terminated - Clinical trials for Non-ischemic Cardiomyopathy

Safety and Efficacy of Doxycycline in Patients With Non-Ischemic Cardiomyopathy

DOXY-HF
Start date: July 2012
Phase: Phase 2
Study type: Interventional

Non-ischemic cardiomyopathy and heart failure are highly influenced by the presence of systemic inflammation. Doxycycline is a FDA-approved drug to treat bacterial infections which also shows powerful anti-inflammatory effects. In this study we plan to determine the effects of Doxycycline in patients with stable heart failure and non-ischemic cardiomyopathy on peak of aerobic exercise capacity (peak V02) and ventilator efficiency measured with a cardiopulmonary test.
