Pulmonary hypertension encompasses a range of conditions directly or indirectly leading to elevated pressures within the pulmonary arteries. Five main groups of pulmonary hypertension are recognized, all defined by a mean pulmonary artery pressure of >20 mmHg: pulmonary arterial hypertension (rare), pu...
PULMONARY hypertensionHEMODYNAMICSPulmonary hypertension (PH) has historically been categorized into 5 groups based on similar pathophysiological mechanisms, hemodynamic characteristics, and therapeutic management. Group 5 has evolved over time in concert with our understanding of PH. Currently, it is ...
pulmonary hypertension. PH is now defined by a mean pulmonary artery pressure (mPAP) > 20 mmHg on resting right heart catheterization and no more ≥25 mmHg (Galiè, McLaughlin, Rubin, & Simonneau, 2019). Pulmonary hypertension has been classified into five groups. The most updated...
World Health Organization Group I Pulmonary Hypertension Introduction:\nThe World Health Organization (WHO) categorizes pulmonary hypertension (PHTN) into 5 groups. Group II classification denotes PHTN secondary to left-heart disease and accounts for nearly 75% of all cases. However, there is ......
There are effective treatments for pulmonary hypertension. Nationally designated specialist centres exist to assist in the diagnosis and treatment of patients with pulmonary hypertension. When patients have unexplained dyspnoea, particularly in high-risk groups, consider pulmonary hypertension. Pulmonary ...
Pulmonary arterial hypertension (PAH) is a chronic and progressive disease leading to right heart failure and ultimately death if untreated. The first classification of PH was proposed in 1973. In 2008, the fourth World Symposium on PH held in Dana Point
Originally described in 1971 (Reuben, 1971), the hyperbolic relationship between PVR and pulmonary compliance has been further studied in pulmonary hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) (Saouti et al., 2009; Lankhaar et al., 2008; Lankhaar et al., 2006)....
A global view of pulmonary hypertension. Pulmonary hypertension is a substantial global health issue. All age groups are affected with rapidly growing importance in elderly people, particularly in countries with ageing populations. Present estimates suggest a pulmonary hyperten...

Pulmonary hypertension (PH) is a severe cardiopulmonary disease characterized by pulmonary vascular remodeling. Immunoglobulin E (IgE) is known to participate in aortic vascular remodeling, but whether IgE mediates pulmonary vascular disease is unknown. In the present study, we found serum IgE elevation...
