Primary pulmonary hypertension, cincinnati children's hospital ...Primary pulmonary hypertension symptom. W: Distension of veins in the neck Swelling of the legs and hands due to fluid retention Enlarged liverAll of these signs are related to the right ventricle working harder to pump blood into the high resistance of the lungs' blood vessels. Diagnosing primary pulmonary hypertension A good history and physical exam can give the physician clues to the diagnosis. An electrocardiogram should be performed which will show enlargement of the right side of the heart. A chest X-ray may show enlargement of the size of the heart, and is often a good way to follow the patient's heart size over time. An echocardiogram, or ultrasound of the heart, will be performed initially and can also be used to follow the progression of the disease. An echo can show enlargement of the right ventricle and can sometimes estimate the pressures of the right ventricle and pulmonary arteries. The gold standard for making the diagnosis of primary pulmonary hypertension is a cardiac catheterization. This will actually measure the pressures on the right side of the heart and the resistance of the blood vessels in the lungs. Various drugs may be used during a cardiac catheterization to determine if the blood vessels in the lungs will relax in response to them. This may lower the pressures in the lungs and can help guide therapy. Return to Top Primary pulmonary hypertension treatment Unfortunately there is no cure for primary pulmonary hypertension. There are some treatments that have been found to relieve some of the symptoms and slow the progression of the disease Oxygen is a drug that can be used at home and |
Symptoms of primary pulmonary hypertension - wrongdiagnosis.comY School of Medicine; and Zab Mosenifar, MD, Professor of Medicine, University of California at Los Angeles School of Medicine; Director, Division of Pulmonary Critical Care Medicine, Executive Vice Chair, Department of Medicine, Cedars-Sinai Medical Center Disclosure INTRODUCTION Section 2 of 11 Author Information Introduction Clinical Differentials Workup Treatment Medication Follow-up Miscellaneous Pictures Bibliography Background: Primary pulmonary hypertension (PPH) is a rare disease characterized by elevated pulmonary artery pressure with no apparent cause. PPH is also termed precapillary pulmonary hypertension or, more recently, idiopathic pulmonary arterial hypertension (IPAH). The diagnosis is usually made after excluding other known causes of pulmonary hypertension. Dresdale and colleagues first reported a hemodynamic account of IPAH in 1951.Pathophysiology: The pathophysiology of IPAH is poorly understood. An insult (eg, hormonal, mechanical, other) to the endothelium may occur, possibly in the setting of increased susceptibility to pulmonary vascular injury (ie, multiple hit theory), resulting in a cascade of events characterized by vascular scarring, endothelial dysfunction, and intimal and medial (smooth muscle) proliferation. At least 15-20% of patients with IPAH have a familial form, which has only recently been characterized. Some cases may be related to sporadic genetic defects. The most common genetic defect in these cases is related to the BMPR-II gene. Early in the disease, as the pulmonary artery pressure increases because of increasing right ven |
