The Changing Landscape of Pulmonary Arterial Hypertension in 21st Century.
نویسنده
چکیده
Pulmonary hypertension (PH) is a severe, progressive disease characterized by an elevated mean pulmonary artery pressure (mPAP) 25 mmHg. 1,2 Five PH subgroups have been recognized, but majority of studies on survival have focused on group 1 pulmonary arterial hypertension (PAH) determined by right heart catheterization (RHC) with a mPAP 25 mmHg, pulmonary arterial wedge pressure (PAWP) < 15 mmHg, and pulmonary vascular resistance (PVR) > 3 Wood units. 3 PAH is characterized by severe remodeling of the distal pulmonary arteries, increased PVR, right ventricular (RV) dysfunction and ultimately heart failure and death. 4

THE EFFECTS OF CAPTOPRIL ON PULMONARY AND SYS TEMIC ARTERIAL PRESSURES IN HIGHALTITUDE PULMONARY HYPERTENSION
The purpose of this investigation was to assess the effect of captopril on both systemic (P.a) and pulmonary arterial pressures (PPA) in patients with high-altitude pulmonary hypertension (HAPH). Seventeen patients (mean age 44±6.8 years) with HAPH and mild to moderate systemic arterial hypertension were included in the study. All patients underwent right heart catheterization with measurem...
متن کاملA case of severe pulmonary hypertension associated with common arterial trunk and VSD in a 9 years old child
Background: Common arterial trunk (CAT) is a rare congenital heart disease, and often leads to the early development of pulmonary hypertension and disability. Among the critical structural heart defects, the frequency of CAT is 3%, which reflects the severe hemodynamic disturbances. The natural course of the disease is characterized by a high mortality rate up to 88% during the first year of li...

Objective(s): The present study was aimed to investigate the influence of thoracic epidural blockade on hypoxia-induced pulmonary hypertension in rats. Materials and Methods: Forty eight Wistar rats were randomly divided into 4 equal groups, named normoxia hypoxia hypoxia/ ropivacaine and hypoxia/saline. Animals were placed in a hypoxia chamber and instrumented with epidural catheters at the t...

متن کاملArrhythmias in Patients With Pulmonary Hypertension; A Narrative Review of the Current Literature
Incidence and prognostic relevance of supraventricular arrhythmias were evaluated in nine studies. These studies investigated patients with different forms of pulmonary hypertension. Supraventricular arrhythmias were more often found in patients with group two pulmonary hypertension. Common findings in these patients were elevated right atrial pressure and diameters and reduced tricuspid annula...
