Active clinical trials for "Heart Diseases"

The purpose of this study is to determine whether ranolazine has beneficial effects on cardiac ischemia through reduction of premature ventricular contraction burden.

HILLCLIMBER is a randomized, controlled, open-label phase II trial of moderate dose statin therapy (pravastatin 40mg daily) versus high-dose statin therapy (rosuvastatin 20-40mg daily) in HIV-infected persons taking antiretroviral therapy (ART) who have coronary heart disease (CHD).

The purpose of this study is to evalute the clinical safety and effectiveness of released specification (38mm) of FirehawkTM Sirolimus target-eluting coronary stent system.

Exercise therapy increase functional capacity improving the morbidity and mortality of patients with cardiovascular disease. Moderate continuous training is the best established training modality for this patients. However, a body of evidence has begun to emerge demonstrating that high intensity interval training obtained better results in terms of morbidity and mortality. The purpose of this randomized clinical trial was to determine the effect of two types of exercise training: moderate continuous training vs high interval training on functional capacity and quality of life as well as verify the safety in its application. We included 72 patients with coronary artery disease by assigning one of the training modality for 8 weeks. We analyzed cyclo-ergo-spirometry data, aspect related to quality of life as well as a record of adverse events.

Introduction: The Fontan operation is the surgical treatment in most patients with either anatomic or functional single ventricles. In this operation, the subpulmonary ventricle is bypassed, connecting the systemic veins directly to the pulmonary arteries. The lack of a subpulmonary ventricle is associated with a nonpulsatile pulmonary flow and triggers a sequence of adaptive mechanisms along the life of these patients. The most frequent consequence of these adaptative mechanisms is the reduction in functional capacity, objectively measured by the decrease in peak oxygen consumption (VO2). So, cardiovascular and pulmonary functioning and skeletal muscle alterations can explain exercise intolerance in these patients. Objectives: 1. To compare the cardiovascular, pulmonary, and musculoskeletal system variables in clinically stable Fontan patients with Healthy subjects; 2. To correlate the variables of the cardiovascular, pulmonary, and skeletal muscle with the functional capacity in Fontan patients; 3. To identify predictors of low functional capacity in this population; 4. To evaluate four-month aerobic exercise and inspiratory muscle training on functional capacity, pulmonary function, and autonomic control in patients after Fontan operation and compare to the group with no exercise training. Methods: All subjects were submitted to cardiovascular, pulmonary, and skeletal muscle evaluation at baseline to perform a cross-sectional study comparing Fontan Patients (FP) with Healthy Controls (HC). In addition, the FP accepted to participate in the longitudinal clinical trial to evaluate exercise programs were randomized into three groups: Aerobic Exercise Training (AET), Inspiratory Muscle Training (IMT), and Non-exercise Training Group (NET, a control group). All patient groups (AET, IMT, NET) were reassessed after four months of training or under usual care. Expected Outcomes: This study expects to demonstrate that impaired pulmonary function, altered neurovascular control, and reduced skeletal muscle could be an additional potential mechanism for reducing functional capacity in clinically stable Fontan patients. And this impairment could be diminished by exercise training, enhancing physical capacity, and exercise tolerance.

In this 94 healthy subjects Phase I clinical trial, we assess the clinical profile of Anfibatide, a specific glycoprotein Ib antagonist. This study represents the first clinical evidence that Anfibatide exhibits strong anti-platelet effects, excellent reversibility, and low bleeding potential in healthy human subjects.

This study was designed to investigate treatment of postoperative pulmonary hypertension by iloprost inhalation in children with congenital heart defects. It was a controlled single-blind randomized multi-center prospective study in order to explore the efficacy of this method in the treatment and prevention of pediatric pulmonary hypertension after corrective open-heart surgery for congenital heart defects.

The choice of fluid therapy is controversial in cardiac surgery. Numerous studies have shown that colloid is better as compared to crystalloids. Several previous studies have demonstrated that Hypertonic Sodium Lactate (HSL) administration during cardiac surgery shows a promising effect. This study aims to compare hemodynamic effects and fluid balance of HSL with 6% Hydroxy Ethyl Starch (HES).

This multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the potential of dalcetrapib to reduce cardiovascular morbidity and mortality in patients with stable coronary heart disease (CHD), with CHD risk equivalents or at elevated risk for cardiovascular disease. Eligible patients will be randomized to receive either dalcetrapib 600 mg orally daily or placebo orally daily, on a background of contemporary, guidelines-based medical care. Anticipated time on study treatment is 4 years.

The purpose of this study is to test a measurement tool and a new training intervention for problem solving in self-management of high cardiovascular disease (CVD) risk in African Americans with type 2 diabetes.
