Prolonged mean VO2 response time in systolic heart failure: an indicator of impaired right ventricular-pulmonary vascular function.
BACKGROUND In patients with left ventricular systolic dysfunction (LVSD), the rate at which oxygen uptake (VO2) increases on initiation of exercise is inadequate to match metabolic demands. To gain mechanistic insights into delayed VO2 kinetics in LVSD, we simultaneously assessed hemodynamic measurements, ventilatory parameters, and peripheral oxygen usage during exercise. METHODS AND RESULTS...
متن کاملEnhanced Pulmonary Vasodilator Reserve and Abnormal Right Ventricular: Pulmonary Artery Coupling In Heart Failure With Preserved Ejection Fraction Andersen et al: Right Ventricular-Pulmonary Artery Coupling in HFpEF
Background—Pulmonary hypertension (PH) and right ventricular (RV) dysfunction are common in patients with advanced HFpEF, yet their underlying mechanisms remain poorly understood. We sought to examine RV-pulmonary artery (PA) functional reserve responses and RV-PA coupling at rest and during -adrenergic stimulation in subjects with earlier-stage HFpEF. Methods and Results—In a prospective trial...
متن کاملPulmonary hypertension and right ventricular function in advanced heart failure.
Pulmonary hypertension (PH) and right ventricular (RV) dysfunction are frequently encountered in patients with advanced heart failure (HF). Both conditions aggravate prognosis and influence clinical decisions. Echocardiography is the screening tool of choice for pulmonary pressures and RV function, although invasive assessment of PH is necessary when advanced therapies are considered. Reversibi...
متن کاملRight ventricular Hemodynamic Alteration after Pulmonary Valve Replacement in Children with Congenital Heart Disease
Introduction: In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...
متن کاملImpaired pulmonary vascular development in bronchopulmonary dysplasia.
Bronchopulmonary dysplasia (BPD), the chronic lung disease associated with preterm birth, results from the disruption of normal pulmonary vascular and alveolar growth. Though BPD was once described as primarily due to postnatal injury from mechanical ventilation and oxygen therapy after preterm birth, it is increasingly appreciated that BPD results from antenatal and perinatal factors that inte...
