Pulmonary hypertension ( PH ) is a life threatening , progressive disease in which there is elevated blood pressure in the arteries supplying the lung . Pulmonary high blood pressure shows an imbalance between endothelial derived vasodilators and vasoconstrictor that causes pulmonary vasoconstriction and vascular proliferation . This causes gap in the rip flow from mettle to the lungs increasing the work load on heart , eventually leading to weakness in the heart muscles . Mean pulmonary arterial pressure above 25 millimetre Hg is considered as pulmonary arterial hypertension .
Pulmonary high blood pressure can be idiopathic ( no known cause ) , known as primary pulmonary hypertension as well as lower-ranking , which results due to other disease . The different case of secondary pulmonic high blood pressure include autoimmune diseases such asrheumatoid arthritisandSLE , connective tissue diseases include scleroderma , CREST syndrome , liver diseases , and inborn heart disease such as atrial and ventricular septal defect , HIV infectionand bilharziasis . Other causes let in drugs such as dieting pills ( fenfluramine and dexfenfluramine ) and unpaid drug , inveterate hindering pneumonic disease ( COPD ) , emphysema , pulmonary fibrosis ( interstitial lung diseases ) , eternal rest apnea , pulmonary embolus , mitral valve disease , chronic systemic elevated blood pressure , polycythemia vera , thrombocythemia , metabolic disorders such as thyroid disease and animal starch storage disease , systemic disorders including sarcoidosis and vasculitis , and kidney diseases .
What are the Symptoms of Pulmonary Hypertension?
The symptoms of pulmonary hypertension come up from increase press in the pulmonary arteria , lead to chokepoint of the blood vessels . This in turn creates spare focus to heart sinew ultimately lead to weakness of kernel muscles with time . The common symptoms of secondary pulmonary high blood pressure are fatigue , difficulty breathing and dizziness . Other symptoms include rapid breathing , exertional shortness of breathing space ( dyspnea ) as well as dyspnea on rest , bureau pain or atmospheric pressure , cyanosis ( bluish discoloration of skin and lips ) , anxiousness , down in the mouth appendage swelling , tachycardia , palpitation , dilatation of jugular vein , ascites ( fluent collection in the stomach ) , clubbing of fingers , non - productive coughing , and exercise inducednauseaandvomiting . In addition , severe pulmonic high blood pressure may also lead to affectionateness failure , blood clots , hemorrhage and arrhythmias .
The diagnosis of pulmonary hypertension is unmanageable to make as the symptoms of pulmonary high blood pressure often overlap those of other philia and lung disease . Therefore , it is not diagnosed until it becomes very wicked . In accession to origin tests , certain imaging tests are also done including correct affection catheterization , echocardiogram ( heartultrasound ) , pneumonic office run , chestX - ray , computed imaging , electrocardiogram , stress testand nuclear medicine lung scan . The treatment programme is based on the results of these trial as these tests also avail in finding out the suit of disease .
What Is The Treatment For Pulmonary Hypertension?
regrettably , there is no definitive treatment for pulmonic hypertension . The objective of the treatment is to slow progression of disease by improve caliber of life of the patient with various therapies . Phosphodiesterase-5 inhibitor ( PDE 5 ) inhibitors induce vasodilatation of the pulmonary blood vessels by facilitating cGMP and NO . PDE 5 inhibitors used are sildenafil ( Revatio ) and tadalafil ( Adcirca ) in unwritten form . Prostacyclin Analogue reduce blood press by relaxation of pulmonary blood vessels . The prostacyclin used is treprostinil , which can be have by word of mouth ( Orenitram ) , inhaled ( Tyvaso ) , IV ( Remodulin ) , and subcutaneously . Endothelin Receptor Antagonists ( ERAs ) prevent vasoconstriction . They are ordinarily taken by word of mouth and the various ERAs used are ambrisentan ( Letairis ) , macitentan ( Opsumit ) and bosentan ( Tracleer ) . Selective IP Receptor Agonist helps in loosen roue vessels in the lungs by activating prostacyclin sense organ . The example is selexipag ( Uptravi ) taken orally . Soluble Guanylate Cyclase ( sGC ) loosen up pulmonary blood vessels by increasing fundamental interaction of sGC with NO . Example include riociguat ( Adempas ) . Other treatment options include calcium channel blocking agent , anticoagulants in the form of warfarin ( Coumadin ) . Digoxin is used for sound mettle pumping , water pill for excess fluid remotion from the body and contrived oxygen in instance of hypoxemia .
In severe case of PH , along with medications surgeries such as atrial septostomy , lung transplantation or heart - lung transplant may be recommended . All the above treatment help prolong endurance charge per unit of pneumonic high blood pressure patients .
