six-minute walk testDetecting pulmonary arterial hypertension (PAH) requires an index of suspicion that is raised by the combination of exertional symptoms and suggestive physical findings such as increased intensity of P2. Cardiac echocardiography is the most useful noninvasive screening test. ...

Porto-pulmonary hypertension (POPH) is defined by the development of PAH associated with increased pressure in the portal circulation [33,34]. Prospective hemodynamic studies have shown that 2-6% of patients with portal hypertension had PH [35,36]. However, RHC is mandatory for the diagnosis of...
However, previous studies of pulmonary function in primary pulmonary hypertension (PPH) (or IPAH) have been contradictory, with normal lung volumes, restrictive ventilatory pattern, and airway obstruction.5, 6, 7 In a German study of PPH, peripheral airway obstruction was common, but that study ...
Patients gradually develop pulmonary hypertension (over years). Symptoms[3–5,11] Presentation varies significantly. High suspicion must be maintained given the risks of complications and mortality . Can be asymptomatic (incidentally found on imaging) Massive PE presents with hemodynamic instability/ shock...
Cardiac investigations: These investigations help confirm the diagnosis, classify the severity, and assess the response to medical therapy. Non-invasive methods are useful in a longitudinal follow-up of pulmonary hypertension. Figure1 - Diagnostic algorithm for evaluation of PH ...
Pulmonology and genetics experts from two Utah healthcare organizations have collaboratively developed a new diagnostic genomic testing method for a rare form of pulmonary hypertension caused by a genetic mutation they discovered three years ago.
COPD is usually associated with mild pulmonary hypertension. However, a subgroup of patients develops severe precapillary pulmonary hypertension disproportionate to the degree of underlying airflow limitation77. These patients suffer from severe, progressive dyspnea and chest CT reveals diffuse emphysema78....
The diagnosis and assessment of pulmonary arterial hypertension is a rapidly evolving area, with changes occurring in the definition of the disease, screening and diagnostic techniques, and staging and follow-up assessment. The definition of pulmonary hypertension has been simplified, and is now based...
According to the diagnostic classification principle of the third pulmonary hypertension meeting at WHO, Italy, Venice, 2003, pulmonary hypertension was observed Pressure (referred to as pulmonary hypertension pulmonary hypertension) for pulmonary circulation system including hypertension, pulmonary hypertension,...
