To amend the Public Health Service Act to provide for the expansion, intensification, and coordination of the activities of the National Heart, Lung, and Blood Institute with respect to research on pulmonary hypertension.

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Pulmonary Hypertension Research Act 
of 2003''.

SEC. 2. FINDINGS.

    The Congress finds as follows:
            (1) In order to take full advantage of the tremendous 
        potential for finding a cure or effective treatment, the 
        Federal investment in pulmonary hypertension must be expanded, 
        and coordination among the national research institutes of the 
        National Institutes of Health must be strengthened.
            (2) Primary, or unexplained, pulmonary hypertension 
        (``PPH'') is a rare lung disorder which occurs for no apparent 
        reason. It has been historically chronic and incurable with a 
        poor survival rate.
            (3) In the United States it has been estimated that 300 new 
        cases of PPH are diagnosed each year, or about two persons per 
        million population per year; the greatest number are reported 
        in women between the ages of 21 and 40. While at one time the 
        disease was thought to occur among young women almost 
        exclusively; we now know, however, that men and women in all 
        age ranges, from very young children to elderly people, can 
        develop PPH. It also affects people of all racial and ethnic 
        origins equally.
            (4) The low prevalence of PPH makes learning more about the 
        disease extremely difficult. Studies of PPH also have been 
        difficult because a good animal model of the disease has not 
        been available.
            (5) In about 6 to 10 percent of cases, PPH is familial.
            (6) In the more advanced stages of PPH, the patient is able 
        to perform only minimal activity and has symptoms even when 
        resting. The disease may worsen to the point where the patient 
        is completely bedridden.
            (7) PPH remains a diagnosis of exclusion and is rarely 
        picked up in a routine medical examination. Even in its later 
        stages, the signs of the disease can be confused with other 
        conditions affecting the heart and lungs.
            (8) In 1981, the National Heart, Lung, and Blood Institute 
        established the first PPH-patient registry in the world. The 
        registry followed 194 people with PPH over a period of at least 
        1 year and, in some cases, for as long as 7.5 years. Much of 
        what we know about the illness today stems from this study.
            (9) Because we still do not understand the cause or have a 
        cure for PPH, basic research studies are focusing on the 
        possible involvement of immunologic and genetic factors in the 
        cause and progression of PPH, looking at agents that cause 
        narrowing of the pulmonary blood vessels, and identifying 
        factors that cause growth of smooth muscle and formation of 
        scar tissue in the vessel walls.
            (10) During the period January 1996 through December 1997 
        almost 6,000,000 Americans took anorexic drugs, which can cause 
        PPH in some people. Thousands now have PPH and are in terminal 
        stages or have already succumbed to the disease. It is 
        anticipated that many more cases of PPH from diet drugs will be 
        diagnosed within the coming years.
            (11) Secondary pulmonary hypertension (``SPH'') means the 
        cause is known. Common causes of SPH are the breathing 
        disorders emphysema and bronchitis. Other less frequent causes 
        are the inflammatory or collagen vascular diseases such as 
        scleroderma, CREST syndrome or systemic lupus erythematosus 
        (``SLE''). Other causes include congenital heart diseases that 
        cause shunting of extra blood through the lungs like 
        ventricular and atrial septal defects, chronic pulmonary 
        thromboembolism, HIV infection, liver disease and certain diet 
        drugs.

SEC. 3. EXPANSION, INTENSIFICATION, AND COORDINATION OF ACTIVITIES OF 
              NATIONAL HEART, LUNG, AND BLOOD INSTITUTE WITH RESPECT TO 
              RESEARCH ON PULMONARY HYPERTENSION.
