Video: Overview of Pulmonary Hypertension

Pulmonary Hypertension is not the same as "regular" high blood pressure or hypertension, which can be easily measured with a blood pressure test.

Pulmonary hypertension is a high pressure in the arteries between the heart and lungs or pulmonary arteries. It is very difficult to detect elevation in pressure in these arteries. Pulmonary Hypertension is a type of vascular disease that can be found in scleroderma patients. (Also see Scleroderma Lung Involvement, What is Scleroderma?, Types of Scleroderma, and Systemic Sclerosis)

Pulmonary hypertension affects all aspects of life. There is a type of high blood pressure that can affect your heart and lungs that is not easily measured. It is an elevation in the pressure in the arteries that carry blood from the heart to the lungs. ReadingEagle, 09/04/12.

Causes

Causes of Pulmonary Hypertension. There are dozens of causes of pulmonary hypertension, ranging from genetics, medications or street drugs, connective tissue diseases (such as scleroderma), heart and lung diseases, and blood disorders. ISN.

Primary Pulmonary Hypertension (PH)

When PH occurs by itself, it is called Primary Pulmonary Hypertension.

Primary pulmonary hypertension occurs by itself and not secondary to another illness, such as scleroderma. Nailfold capillary examination can easily tell whether pulmonary hypertension is primary or secondary. (Also see Nailfold Capillaroscopy)

Secondary Pulmonary Hypertension

Treatments and their effectiveness can vary
depending on whether PH is primary or secondary.

Secondary Pulmonary Hypertension. When PH occurs along with other lung, heart, or systemic connective tissue disease (such as scleroderma), it is called Secondary Pulmonary Hypertension. The distinction is important because treatments, and their effectiveness, can vary depending upon whether the pulmonary hypertension is primary or secondary. ISN.

Exercised Induced

Influence of Pulmonary Vascular Reserve on Exercise-Induced Pulmonary Hypertension (PH) in Patients with Systemic Sclerosis (SSc). The present study demonstrated that exercise-induced PH was common in patients with SSc. Exercise-induced PH might be closely associated with the factors affecting reduced pulmonary vascular reserve in patients with SSc. PubMed, Echocardiography, 2014 Aug 8.

Clinical and echocardiographic correlations of exercise-induced pulmonary hypertension in systemic sclerosis. Exercise-induced increase in pulmonary arterial systolic pressure (PASP) occurs in almost one-half of patients with systemic sclerosis (SSc) with normal resting PASP. American Heart Journal, November 2012.

Correlation with Other Diseases

Impact of pulmonary fibrosis (PF) and elevated pulmonary pressures (PHT) on right ventricular (RV) function in patients with systemic sclerosis (SSc). SSc patients show impaired RV function and both pulmonary fibrosis and PHT are independently associated with RV dysfunction. PubMed, Rheumatology (Oxford),2016 Mar;55(3):504-12. (Also see Cardiac (Heart) Involvement)

Relationship of main pulmonary artery diameter to pulmonary arterial pressure (PH) in scleroderma patients with and without interstitial fibrosis. In scleroderma patients, an enlarged main pulmonary artery predicts PH even in the presence of mild to moderate fibrosis. PubMed, J Comput Assist Tomogr, 2014 Mar-Apr;38(2):163-8. (Also see Correlation of Pulmonary Fibrosis and Pulmonary Hypertension)

Borderline pulmonary arterial pressure (BoPAP) in systemic sclerosis patients: a post-hoc analysis of the DETECT study. In this exploratory post–hoc analysis of the DETECT study population patients with BoPAP could be distinguished from patients with normal mean pulmonary artery pressures and pulmonary arterial hypertension. PubMed, Arthritis Res Ther, 2014 Dec 10;16(6):493.

Evidence-based detection of pulmonary arterial hypertension (PAH) in systemic sclerosis (SSc): the DETECT study. The novel, evidence-based DETECT algorithm for PAH detection in SSc is a sensitive, non-invasive tool which minimises missed diagnoses, identifies milder disease and addresses resource usage. PubMed, Ann Rheum Dis, 2014 Jul;73(7):1340-9. (Also see Systemic Sclerosis)

Proteome-wide Analysis and CXCL4 as a Biomarker in Systemic Sclerosis. Levels of CXCL4 were elevated in patients with systemic sclerosis and correlated with the presence and progression of complications, such as lung fibrosis and pulmonary arterial hypertension. The New England Journal of Medicine, 12/18/2013. (Also see Biomarkers and Pulmonary Fibrosis)

Diagnosis

Diagnosis of Pulmonary Hypertension. Doppler echocardiograms are notoriously inaccurate when the PH is mild or when there is simultaneous presence of lung scarring. PH cannot be diagnosed without right heart catheterization. ISN.

Prognosis

Prognosis of Pulmonary Hypertension. Early diagnosis and treatment substantially improves the prognosis for pulmonary hypertension associated with systemic sclerosis (scleroderma). ISN.
