NCT02668250
With the increasing aging population demographics and life expectancies, the number of very elderly patients undergoing surgery is rising. Elderly patients constitute an increasingly large proportion of the high-risk surgical group. Cardiac complications and postoperative pulmonary complications are equally prevalent and contribute similarly to morbidity, mortality, and length of hospital stay. Specific optimization strategy of general anesthesia has been tested in high-risk patients undergoing major surgery to improve outcomes. Our hypothesis is that a combined optimization strategy of anesthesia concerning hemodynamic, ventilation, and depth of anesthesia may improve short- and long- term outcome in elderly undergoing high risk surgery.
NCT03326778
This is a prospctive, unrandomized multicentric registry which will enrol patients with an indication for aortc valve replacement combined with myocardial reperfusion (CABG). The registry will collect patient specific baseline data and established risk scores (Logistic Euroscore I \& II, STS-Score, KBA Score) to enable us to make an estimate about the perioperative risks.

NCT00958061
Little is known about the long-term health and mental health status of women Vietnam veterans. For many of these women, the effects of this war are still present in their daily lives. As these women approach their mid-sixties, it is important to understand the impact of wartime deployment on health and mental health outcomes nearly 40 years later. The investigators propose to assess the prevalence of posttraumatic stress disorder (PTSD) and other mental and physical health conditions for women Vietnam veterans, and to explore the relationship between PTSD and other conditions and the Vietnam deployment experience. The investigators are interested in studying women Vietnam veterans who may have had direct exposure to traumatic events. For the first time, the investigators also want to study those who served in facilities near Vietnam. These women may have had similar, but less direct exposures. This cross-sectional study will seek to contact approximately 10,000 women for participation in a mailed survey, telephone interview and a review of their medical records. Women identified as serving in Vietnam, near Vietnam (in Asia during the Vietnam Ware) and in the U.S. during the Vietnam War will be identified from an established cohort and sent a survey on demographics, behaviors, disability, health-related quality of life, and medical conditions. Women agreeing to be contacted will also be interviewed by study investigators using the modified CIDI to ascertain current and lifetime mental health conditions (including PTSD) and exposure to traumatic events. A more extensive chart review will be conducted by a clinician to validate self-report of key medical conditions.
NCT03827954
In the current application, the investigators propose to elaborate upon, reconstruct and advance to pivotal trial readiness a recently validated mobile application (HeartMapp), designed for the ecological momentary assessment and treatment of individuals with Heart Failure (HF). Presently, HeartMapp includes physiological modules (PM) that support self-monitoring and exercises that promote heart health, and cognitive modules (CM) that track and enhance cognitive functions. During the first three-months, the investigators will finalize the cognitive training modules within HeartMapp and release through the quality management system. At the completion of software development, the investigators propose to test the relevant usage and progression variables of the algorithm that will be used to direct engagement with the app. The investigators will conduct a single arm, open label, pilot clinical trial to examine feasibility and initial efficacy of the HeartMapp+CT (HeartMapp and computerized plasticity-based adaptive cognitive training). The term "CT" refers to computerized training. The study will enroll 32 adults aged 40 and older with a diagnosis of HF and over sample by 25% to reduce attrition for a total of 24 participants enrolled at the end. Participants will complete follow-up assessments at 3- and 6-months after enrollment.
NCT05019443
Stent under-expansion during percutaneous coronary intervention (PCI) is one of the suboptimal results associated with a higher risk of restenosis and thrombosis. In order to obtain an optimal stent expansion, especially in lesions with calcific or fibrotic plaque, the appropriate lesion preparation before stent implantation is a crucial phase. For this, different devices are used in everyday practices, including non-compliant balloon (NC), scoring / cutting balloons or rotational atherectomy; however, their effectiveness depends on the experience and skill of the operator. The purpose of this study is to assess the feasibility, efficacy and safety of a novel scoring balloon intended to treat calcific or fibrotic plaque of a coronary lesion
NCT01337011

NCT04934241
This study will be conducted to evaluate the effect of acupressure applied to patients with coronary artery disease (CAD) on pain and sleep quality.
NCT05016726
To evaluate intra-procedural and long-term effects of intravascular lithotripsy with the ShockWave System and/or non-balloon mechanical debulking devices, prior and/or after coronary stenting in an angiographically well-defined group of patients with complex calcified coronary artery lesions.
NCT05017077
Heart failure is a complex clinical syndrome, representing the final evolution of many cardiac diseases that may differ for etiology and pathophysiology. In pediatric population, it is particularly challenging to manage because of the heterogeneity in age, primary cardiac disease, and the broad range of clinical signs and symptoms. Frequent hospitalizations are current problem. Hospitalization within the first year since the first episode, lack of adherence to medical therapy and diet difficulties are the main issues in this population of patients, and they rebounds on prognosis and public health costs. Actions aimed to prevent and manage these matters will improve outcome in patients with chronic heart failure. Telemedicine proved its usefulness in adult population, but, nowadays, no studies have been conducted in children. From the beginning of 21th century, remote monitoring attempts have been adopted, initially by phone calls. Currently, the e-care monitoring fits in the context of telemedicine 2.0 based on new communication models. The aim of this study is to affirm the feasibility and efficacy of a new model of tele monitoring in pediatric population. High-risk patients need a strict clinical control normally difficult to adopt. A telematics system capable to detect vital parameters as heart rate, body temperature, blood pressure, oxygen saturation, breathe frequency, weight, arrhythmias and cardiac index may offers to physician valuable information able to strictly monitoring the clinical status of patients. All of these data permits to physician to early detect critical signals of a deteriorated status, modify adherence to care and implement therapeutic strategies in order to prevent frequent hospitalizations. Our project provides a system of continuous tele-monitoring of vital parameters through a patch applied on the chest of the baby. Data are sent to a service center, "virtual clinic" and daily analyzed in multiparametric system by a specialized nurse. On the basis of pre-established alarms, the virtual clinic will notify to physician. Feasibility and tolerability of this new monitoring system will be evaluated after a 3 months period on a cohort of 20 patients affected by chronic, high-risk, heart failure.

A secondary goal is to determine of a period of medical management attenuates this sleep disordered breathing-induced cardiac injury in this patient population.
NCT04854200
The purpose of HVAD Smart 1.0 study is to collect HVAD device data (i.e., waveform + logfile + pump parameter) in various clinical conditions (e.g., routine follow-up visits, experiencing adverse events) to support development of predictive and actionable algorithms. The collected data will be used to characterize HVAD flow waveform and logfile pattern changes that precede a qualifying adverse event, as well as characterize "normal" HVAD flow waveform and logfile patterns (subjects free from any qualifying adverse event, any hospital readmissions related to a SAE, or any parenteral medical therapy for heart failure management (e.g., inotropes, diuretics, etc.) or ultrafiltration in last 30 days). In addition, the study will collect data to evaluate the utility of CareLink in HVAD patients. The study will not involve any investigational testing and the market-released devices will used as per the approved labelling.
NCT02693262
Dr. Jonathan Hsu and Dr. Eric Adler are conducting a research study to find out more about how implantable cardiac defibrillator (ICD) settings can be adjusted to improve patient cardiovascular health and quality of life. Patients are being asked to participate in this study if they have a history of heart failure and have or are scheduled to be implanted with a BIOTRONIK ICD that is capable of closed loop stimulation (CLS). CLS is a device setting that works with the cardiovascular system to optimize their heart rate during physical activity. This study is comparing BIOTRONIK's CLS setting to a standard accelerometer setting, which also is able to adjust the heart rate by movement sensors, when necessary. This study has been initiated by Dr. Hsu and Dr. Adler and is financially supported by BIOTRONIK, Inc. There will be approximately 15 participants in this trial.
