Pulmonary arterial hypertension (PAH) is a condition involving high blood pressure and structural changes in the walls of the pulmonary arteries, which are the blood vessels that connect the right side of the heart to the lungs. Affecting people of all ages and ethnic backgrounds - but most commonly found in young women of child-bearing years - the disease has historically been chronic and incurable, with a poor survival rate. PAH is often not diagnosed in a timely manner because its early symptoms can be confused with those of many other pulmonary and respiratory conditions. Symptoms include shortness of breath, extreme fatigue, dizziness, fainting, swollen ankles and legs and chest pain (especially during physical activity). With proper diagnosis, there are currently several therapies to alleviate symptoms and improve quality of life for PAH patients. The key is to find a PAH specialist and pursue immediate treatment.
Clinicians should use echocardiography, an ultrasound that shows the heart's structure and function, when determining whether patients with heart failure and a leaking heart valve are likely to benefit from valve repair, according to research presented at the American College of Cardiology's 68th Annual Scientific Session.
Since the advent of effective antiretroviral therapy, human immunodeficiency virus infection has become more like a chronic illness.
More than 120 professionals from the field of health and other experts from thirty-three countries worldwide have taken part in the social awareness event of the EUDONORGAN project, an initiative directly launched by the European Parliament and led by the University of Barcelona, together with the Bosch i Gimpera Foundation and the DTI - TPM Foundation, located at the Barcelona Science Park.
Specialized lung cells appear in the developing fetus much earlier than scientists previously thought. A new animal study reports how cells that become alveoli, the tiny compartments in which gas exchange occurs in the lung, begin their specialized roles very early in prenatal life.
Specialized lung cells appear in the developing fetus much earlier than scientists previously thought. A new animal study published this week in the Proceedings of the National Academy of Sciences reports how cells that become alveoli, the tiny compartments in which gas exchange occurs in the lung, begin their specialized roles very early in prenatal life.
The American Thoracic Society has developed a new clinical practice guideline for home oxygen therapy for children. The guideline appears in the Feb. 1 edition of the Society's American Journal of Respiratory and Critical Care Medicine.
A protein with a role in sensing cell damage and viral infections is a new target for the treatment of pulmonary hypertension, or increased blood pressure in the lungs, according to research led by Virginia Commonwealth University and the University of Sheffield in the United Kingdom.
Scientists from Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago and colleagues identified promising new genetic pathways associated with severe lung disease in extremely premature infants, as well as pathways linked to faster recovery from lung disease in this population.
Two related enzymes have opposing roles in mouse heart muscle cells exposed to pressure overload, according to a recent study published in the Proceedings of the National Academy of Sciences, USA.
Dr. Lesley Ann Saketkoo, an associate professor of clinical medicine at Tulane University School of Medicine, has been named Doctor of the Year by the Scleroderma Foundation. The award recognizes leadership and commitment to the community battling scleroderma, a disabling and life-limiting multi-organ autoimmune disease with progressive lung, heart, kidney, gastrointestinal tract and/or vascular involvement.
While in search of the causes of allergies and asthma, a chance discovery has yielded new clues: researchers led by Dr Marcus Peters have ascertained that the enzyme guanylate cyclase in cells lays the foundations for the type of immune response.
The new journal Cardiovascular Innovations and Applications has just published the first issue of Volume 3. This is a Special Issue on Adult Congenital Heart Disease with Guest Editor Diego Moguillansky of the University of Florida Medical School.
New and better ways to fight hypertension and low blood pressure may be in the offing, thanks to the National University of Singapore scientists' discovery of how our blood pressure is controlled.
Makers of brand-name drugs called out by the Trump administration for potentially stalling generic competition have hiked their prices by double-digit percentages since 2012 and cost Medicare and Medicaid nearly $12 billion in 2016, a Kaiser Health News analysis has found.
Researchers from the Wolfson Faculty of Chemical Engineering at the Technion-Israel Institute of Technology have developed an integrated system for early diagnosis of diseases using wearable monitors.
A new and early target for treating pulmonary hypertension appears to be an enzyme that's normally key to energy production but destructive in the face of this high blood pressure inside your lungs.
In a recent study, scientists found that eliminating the FoxM1 gene could improve outcomes for patients with pulmonary hypertension.
In the current issue of Cardiovascular Innovations and Applications (Volume 2, Number 4, 2018, pp 439-446(8); DOI: https://doi.org/10.15212/CVIA.2017.0027, researchers Yee-Ping Sun and Patrick T.

Working with cells that line the innermost layer of the blood vessels, Johns Hopkins investigators say they have made a leap forward in understanding the underlying biology behind pulmonary hypertension, a dangerous type of high blood pressure in lungs that ultimately leads to right heart failure and death.
A small, daily dose of Viagra significantly reduces colorectal cancer risk in an animal model that is genetically predetermined to have the third leading cause of cancer death, scientists report.
