fit in to WHO , there are five types of pulmonary high blood pressure rank from eccentric 1 to type 5 . Type 1 relates to numerous causes admit connective tissue diseases ( autoimmune diseases ) , liver diseases , congenital heart disease , HIV infection , schistosomiasis ( parasitic contagion ) , due to drugs ( include some of diet pills and amateur drug ) . This group also include idiopathic and transmitted cause . Type 2 PH is because of condition affecting left side of the heart including mitral valve disease and continuing systemic lofty ancestry pressure . character 3 PH is come to to various lung condition such aschronic obstructive pulmonary disease ( COPD ) , pulmonary fibrosis ( interstitial lung disease ) , andsleep apnea . Type 4 PH is associated with coagulate disorders such as pulmonary emboli . Type 5 PH includes blood upset ( polycythemia vera and thrombocythemia ) , metabolic upset including thyroid gland diseases and animal starch storage disease , systemic disorder ( such as sarcoidosis and vasculitis ) , reap hook cell disease , kidney diseases and other weather including tumors make compaction of pulmonary artery .
Pulmonary Hypertension Treatment Guidelines
The update 2015 European Society of Cardiology / European Respiratory Society guidelines for pulmonary hypertension treatment include the pursuit :
pneumonic high blood pressure is considered a pathophysiological disease , which involves one or more other disease and can worsen other respiratory and cardiovascular diseases . PH is a DoS of increased pneumonic arteria pressure , greater than 25 millimeter Hg , in pneumonic arteria when measured by ripe heart catheterization . The normal pneumonic artery pressure should be less than 20 mm Hg . multitude who have pneumonic arterial blood vessel pressure sensation in 21 - 24 mm Hg range have a greater risk of acquire PH .
There is confusion in classification of PH that may result to overtreatment of patient role . Pulmonary arterial hypertension ( PAH ) is just a subgroup ( type 1 ) of PH with precapillary PH . mail capillary PH is relate to impart heart and valve disease . It is interesting to note that about 50 % cases of PAH are either idiopathic , hereditary or drug induced .
Transthoracic echo is used as an initial screening / symptomatic approach , but for treatment , right heart catheterisation is necessary . VQ scan is the preferred CAT scan for screening of chronic catheterisation PH . Cardiac MRI is prefer when control syllable structure , function and mass in right ventricle of substance and is utile in prognosis and handling of congestive heart loser . It should be noted that in patients with non - idiopathic PAH , right-hand sum failure and/or humbled cardiac output signal ; calcium canal blockers should be used guardedly as they might cause vasoreactivity .
General treatment principle include proper diagnosis of the patient and classifying them according to WHO compartmentalization and do by them according to that . PAH should be differentiated with other PH and right heart catheterisation should be performed for confirmation . Treatment measures also include life style modification with free weight ascendancy , staying active with physical activeness , pulmonary rehabilitation . fair sex should forbid pregnancy and should be on combining therapy of birth control tablet along with PAH specific treatment . These patient role should get psychological and social financial support , they should be up - to - date on various vaccine such as seasonal influenza and pneumonia .
The patients suffering from PH are deficient in atomic number 26 and are usually anaemic , so they should take branding iron supplements and should be treated for anemia . Patients who have less grave form of pH scale can be treated with unwritten medications , but compounding therapy of oral and inhaled medications should be considered in patients who are on monotherapy and still have persistence of symptom . Severe contour of pH scale and rapidly advance PH in patient on oral / inhalator should be treated with IV and/or subcutaneous drugs such as Flolan , Tyvaso and Remodulin .
Oral anticoagulant therapy should be start up in inheritable and idiopathic PAH . If patients are hypoxemic , they should be pass on oxygen therapy . PH patients should be prescribed diuretic for diminution of correct ventricular failure symptom . In continuative to PH specialiser , other medical specialist should also be confab in case of pregnancy , elective / pressing / emergency surgical operation in PH patients . patient role distrust for PAH should be referred to PH specialist for verification of diagnosis before initiation of treatment and should accompany up with them regularly to monitor reception , subsequent therapy decisions such as lung transplant considerateness and referral .
