Pulmonary high blood pressure ( PH ) also known as pulmonary arterial hypertension ( PAH ) is a serious reformist disease , in which there is elevated line insistency in the arteria supplying the lungs . The blood rate of flow from the heart to the lungs is disrupted due to constriction in blood vessels causing elevated pulmonary arterial pressure . Normal insistence in pulmonary arteries include 15 - 30 mm Hg systolic imperativeness and 4 - 12 mm Hg diastolic imperativeness . If the pressure is keen than 30/12 millimeter Hg , then it is known as pulmonary high blood pressure .
What is Secondary Pulmonary Hypertension Caused By?
Pulmonary high blood pressure can be cause due to unknown intellect , fuck as primary pulmonic hypertension . When pulmonic hypertension is get secondary to some other disease then it is known as secondary pulmonic hypertension .
The different causes of secondary pulmonary high blood pressure include autoimmune diseases such asrheumatoid arthritisand SLE , connective tissue paper disease ( scleroderma , CREST syndrome , lupus ) , liver diseases , congenital heart disease ( atrial and ventricular septal defects ) , reap hook cell anemia , HIV infection and schistosomiasis ( parasitic infection ) . It can also be have due to drug and certain toxin including some of diet pills ( such as fenfluramine and dexfenfluramine ) and recreational drugs . It can also be because of various breathing and lung conditions such aschronic obstructive pneumonic disease ( COPD ) , emphysema , pulmonary fibrosis ( interstitial lung disease ) andsleep apnea . In addition , it can also be triggered by clotting disorder such as blood clots in the lung ( pulmonary embolus ) along with disease affecting small rake vessel in the lung .
Heart failureand other stipulation affecting left side of the substance including mitral valve disease and chronic systemic elevated rakehell press can also do subaltern PH . In add-on , causes of secondary PH include blood disorders ( polycythemia vera and thrombocythemia ) , metabolic upset such as thyroid gland diseases and glycogen storage disease , systemic disorders ( such as sarcoidosis and vasculitis ) , kidney diseases and other conditions including neoplasm causing compression of pneumonic arteries .
pneumonic high blood pressure is more prevalent in females than in males around the age group of 30 to 40 .
Symptoms of Secondary Pulmonary Hypertension
The symptoms of secondary pulmonary high blood pressure arise due to increase insistency in the pulmonary arteries , leading to tightness of the blood vessels . This in round creates supererogatory tenseness to heart muscles ultimately leading to weakness of nerve muscles with time . The common symptoms of secondary pulmonic high blood pressure are weariness , trouble breathing and vertigo . Other symptoms let in rapid respiration , exertionalshortness of breath(dyspnea),chest pain , anxiety , lower extremity swelling , tachycardia , distention of jugular vein , ascites(fluid solicitation in the abdomen ) , and club of fingers . In addition , knockout secondary pulmonary hypertension may also take to gist failure .
Diagnosis and Treatment of Secondary Pulmonary Hypertension
The diagnosing of pulmonary high blood pressure is difficult to make as the symptoms of pneumonic high blood pressure often overlap those of other philia and lung diseases . Therefore , it is not diagnosed until it becomes very grievous . In summation to descent tests , certain mental imagery tests are also done including good heart catheterization , echocardiogram ( heartultrasound ) , pulmonary office tests , thorax cristal - beam of light , compute imaging , electrocardiogram , focus test and nuclear medicine lung scan . The treatment plan is based on the results of these tests as these mental testing also help in finding out the cause of disease .
Unfortunately , there is no classic handling / cure for pulmonary high blood pressure . The aim of the handling is focused on slowing / hold up the progression of the disease by improving the quality of life story of the patient with medications to lower blood pressure , thinning of blood , aid heart to pump more efficiently , opening up constricted roue vas and remove supererogatory fluid from the body . This is attain by treating rudimentary cause with the help of rip thinner , diuretic drug , lowering blood pressure and dilatation of lineage vessels . On occasions , the patient might also call for oxygen subjunction in cases of difficulty in breathing .
The prognosis of patients with pneumonic hypertension is generally misfortunate , but with the Parousia of fresh medicine and more research and subject , there seems to be a hope for greater life anticipation in the people suffer from this life - threatening disease .
