Primary pulmonary hypertension causes shortness of breath
By admin | June 27, 2008
Primary pulmonary hypertension is a serious disease which causes shortness of breath. The lungs are the critical respiration organ in air-breathing animals, including most four-legged creatures and some fish and snails. Pulmonary heart disease is a complication of either acute or chronic lung disease. Because it does not develop until the lung disease is at an advanced stage, pulmonary heart disease is difficult to diagnose in an early stage. To compensate for the extra work needed to force blood through the lungs, the right ventricle dilates and enlarges. An increase in pulmonary artery pressure is caused due to the narrowing of the pulmonary blood vessels leading to restriction of pulmonary circulation, lesser gas exchange in the lungs and higher strain on the right ventricle concluding in the failure of the right ventricle. Eventually, this leads to right ventricular failure. When an individual’s lungs are damaged from infection, smoking, or inhaling toxins, or if they develop an embolus, the blood pressure in the arteries leading from the heart to the lungs can increase and force the heart to work harder to get the blood into the lungs to be oxygenated. The usual treatment for pulmonary heart disease is the same as that for congestive heart failure, in which calcium channel blockers are prescribed to dilate the pulmonary blood vessels and reduce the blood pressure in the lungs.
