Postgraduate medicine: how to manage secondary pulmonary hypertension

Secondary pulmonary hypertension. MD VOL 105 NO 2 FEBRUARY 1999 POSTGRADUATE MEDICINE CME learning objectives To become familiar with normal pulmonary vascular physiology To learn common signs and symptoms of pulmonary hypertension To understand diagnostic approaches and treatment options for cor pulmonale and chronic thromboembolism This page is best viewed with a browser that supports tables Preview: Pulmonary hypertension is often difficult to diagnose, because it presents with nonspecific cardiorespiratory findings that reflect abnormal pulmonary vasculature and not the underlying cause. Knowledge of normal pulmonary vascular physiology is imperative in determining possible sources of the hypertension. The authors describe the three major categories of secondary pulmonary hypertension and management of two specific forms. Part 2 of this article, which describes primary pulmonary hypertension, will appear in the March issue. Pulmonary hypertension is a common response to abnormalities of cardiac and pulmonary function. However, defining pulmonary hypertension physiologically can lead to omission of specific diseases for which early treatment is effective. In addition, the approach ignores the important contribution of pulmonary hypertension and right ventricular failure to morbidity and mortality in several common heart and lung disorders. Before physicians can make appropriate management decisions, they must have a thorough understanding of normal pulmonary vascular physiology. Pulmonary vascular physiology Soon after birth, the right ventricular systolic pressure required to open the pulmonic valve an secondary pulmonary

Sts only a few minutes in circulation and must be continuously infused through an intravenous (IV) catheter via a small pump that you wear in a pack on your belt or shoulder. This requires that you learn to prepare your own medication mixture, operate the pump and care for the IV catheter. You must also receive comprehensive follow-up care. Potential side effects of epoprostenol include jaw pain, nausea, diarrhea, leg cramps, as well as pain and infection at the IV site. A newer form of the drug, iloprost, avoids many of these problems. Iloprost can be inhaled through a nebulizer, making it far more convenient and less painful to use. And because it's inhaled, it goes directly to the lungs. Side effects associated with iloprost include chest pain — often accompanied by headache and nausea — and breathlessness. What's more, iloprost must be inhaled about every three hours and is extremely expensive to use. Another prostacyclin, treprostinil, is injected under the skin. Endot

It occurs when blood travels through the body's arteries at a pressure too high for good health. A far less common type of high blood pressure affects only the arteries in the lungs. Known as pulmonary hypertension secondary pulmonary hypertension, it is a serious illness that becomes progressively worse and eventually may prove fatal. Pulmonary hypertension begins when the lungs' tiny arteries narrow or become blocked. This causes increased resistance to blood flow in your lungs secondary pulmonary hypertension, which in turn raises pressure within the pulmonary arteries. As the pressure builds secondary pulmonary hypertension, your heart's right ventricle must work harde secondary pulmonary hypertension.

In the SI (metric) system secondary pulmonary hypertension, one mmHg = 133.322 Pascals (Pa) MPAP (also called MAP) Mean (average) Pulmonary Artery Pressure - average pressure in the pulmonary artery. In the formula secondary pulmonary hypertension, diastole (heart's relaxation phase) counts twice as much as systole (heart's contraction phase) because 2 3 of the heart's cycle is spent in diastole Formula: (2 times DPAP) plus SPAP divided by 3 Normal range = 10 to 16 mmHg PAOP Pulmonary Artery Occlusion Pressure - same as PCWP PAP same as MPAP PAWP Pulmonary Artery Wedge Pressure - same as PCWP PCWP (also called PAWP and PAOP) Pulmonary Capillary Wedge Pressure - an indirect measurement of pressure in the heart's left atrium. Directly monitored during pulmonary cath Normal range = 5 to 13 mmHg PFT Pulmonary Function Tests - tests to see how well your lungs work PH Pulmonary Hypertension - state of high pressure in your lungs' blood vessels.
