The First-In-Man Pilot Study of Firehawk

Coronary Heart Disease

This is a small-scale pilot clinical study of the Rapamycin-Eluting Coronary Stent System of Microport for the first time to assess the preliminary safety and feasibility used in the human body. And provide evidence for subsequent large-scale, multi-center, randomized controlled clinical trials, then provide the basis for the formal application of the product in China.

The Health Impact of High Intensity Exercise Training With Intervals During Cardiac Rehabilitation...

Heart DiseaseHeart Attacks

Cardiac rehabilitation is a program designed to help patients regain good health through lifestyle change after a heart attack, heart surgery or other heart problems. Patients will take part in exercise sessions and education lessons, tailored to meet their personal needs. The exercise training component of cardiac rehabilitation may be delivered as intervals of short intense sessions (also known as high intensity intervals) or the current standard care of longer but less intense sessions (moderate intense intervals). Both exercises have been shown to increase fitness levels and also prevent future risk of heart disease. The purpose of this study is to determine the efficacy and safety of high intensity interval exercise training (HIIT) in patients who had a recent cardiac revascularization procedure or recovering from a heart attack, in comparison to current standard of moderate intensity exercise training in terms of their physical fitness and psychological well-being.

STeroids to REduce Systemic Inflammation After Infant Heart Surgery

Congenital Heart Disease in ChildrenInflammatory Response

This study's objective is to determine the pharmacokinetics (PK)/pharmacodynamics (PD), safety and efficacy of methylprednisolone in infants undergoing heart surgery with cardiopulmonary bypass. This is a prospective, double blind, multi-center, placebo-controlled safety and efficacy study. Blood samples will be collected from a subset of enrolled study participants to evaluate multiple dose methylprednisolone PK/PD. Participants will be randomized in a 1:1 fashion to intravenous methylprednisolone versus placebo. Study drug/placebo will be administered 8 to 12 hours before the anticipated start time of surgery and in the operating room at the time of initiation of cardiopulmonary bypass. Patients will be followed for primary and secondary outcomes for the duration of their hospitalization. Serious study drug-related adverse events will be collected for 7 days after the last dose of study drug.

CPAP Treatment and Postoperative Outcomes in Patients With Rheumatic Valvular Heart Disease

Rheumatic Valvular Heart DiseaseObstructive Sleep Apnea

The prevalence of OSA (Obstructive sleep apnea,OSA) is 2%-4% in general population and 16%-47% in surgical-heart failure patients. Our previous study found that OSA was associated with the increasing incidence of perioperative adverse events.The continuous positive airway pressure (CPAP), as the standard treatment for OSA, is extensively applied clinically. The previous study reported that postoperative AHI was reduced and SPO2 was increased by CPAP treatment. However, whether CPAP treatment can improve OSA postoperative and related adverse events or not in patients with rheumatic valvular heart diseases (RVHD) were not reported.The purpose of this study is to observe the effective of preoperative CPAP on postoperative sleep parameters and adverse events, such as AHI changes, duration of ICU stay and duration of mechanical ventilation.

Evaluation of Safety and Efficacy of Lumason in Pediatric Echocardiography

Heart Disease

Safety and Efficacy Study in pediatric subjects aged 9 to 17 years of age with suboptimal LV EBD on non-contrast 2D echocardiography. Imaging modalities that are used throughout the study in pediatric subjects represented those utilized in routine clinical practice in adults.

A Study to Assess the Safety, Tolerability, and Effects of MK-0974 (Telcagepant) on Exercise Tolerance...

Angina PectorisCoronary Heart Disease1 more

This study will assess the safety of telcagepant in coronary artery disease (CAD) participants with stable angina during exercise treadmill testing and evaluate whether calcitonin gene-related peptide (CGRP) receptor antagonism by telcagepant reduces exercise tolerance in these participants. Primary hypothesis is that telcagepant does not significantly decrease exercise duration compared to placebo, as measured by a treadmill exercise test; that is, the true treatment difference in exercise duration (MK-0974 - Placebo) >= -60 seconds.

Inhaled Milrinone Use in Patients Receiving HeartMate II LVAD: A Pilot Study

End Stage Heart DiseaseRight Ventricular Dysfunction

Right ventricular (RV) failure occurs in an estimated 5-41% of cases involving left ventricular assist device (LVAD) implantation and has been shown to adversely affect peri-operative morbidity and mortality. Current therapies to improve RV dysfunction pre and post-operatively are limited. Inhaled milrinone has been shown in several small human studies to be safely tolerated and provide favorable effects on pulmonary hemodynamics. Study Hypothesis: Delivery of inhaled milrinone, a phosphodiesterase III inhibitor, may provide pulmonary artery vasodilation and therefore improved RV function in patients with end stage heart failure receiving HeartMate II LVAD as a bridge to cardiac transplantation or as destination therapy. Specifically, we aim to: demonstrate safety of inhaled milrinone in this patient cohort demonstrate efficacy of inhaled milrinone in this patient cohort

A Clinical Trials of Quick-Acting Heart Reliever for Moderate Coronary Stenosis

Coronary Artery StenosisCoronary Heart Disease

This study investigates the effective power of angina pectoris after Quick-Acting Heart Reliever and isosorbide dinitrate interventing respectively the patients with moderate coronary stenosis for six months. At the same time, the studying will assess the plaque, myocardial blood-supplying,quality of life and observe the end point of the heart (including the myocardial revascularization, death and myocardial infarction). The purpose is to study the function of the blood-quickening stasis-transforming formula Quick-Acting Heart Reliever for moderate coronary stenosis lesions.
