Drug for erectile dysfunction improves heart function in young heart-disease patients
Heart function significantly improved in children and young adults with single-ventricle congenital heart disease who have had the Fontan operation following treatment with sildenafil, a drug used to treat erectile dysfunction and pulmonary hypertension, say researchers from The Children's Hospital of Philadelphia.   view more (2009-11-19)

When seconds count: Interventional radiology treatment for pulmonary embolism saves lives
Catheter-directed therapy or catheter-directed thrombolysis-an interventional radiology treatment that uses targeted image-guided drug delivery with specially designed catheters to dissolve dangerous blood clots in the lungs-saves lives and should be considered a first-line treatment option for massive pulmonary embolism, note researchers in the... view more...

Drugs to treat anemia in cancer patients linked to thromboembolism
Medications frequently given to cancer patients to reduce their risk of anemia are associated with an increased risk of deep vein thrombosis or pulmonary embolism, according to new research led by Dawn Hershman, M.D, M.S., co-director of the breast cancer program at the Herbert Irving Comprehensive Cancer Center at NewYork-Presbyterian... view more...

Study shows hormone replacement therapy decreases mortality in younger postmenopausal woman
Hormone replacement therapy (HRT) to treat menopausal estrogen deficiency has been in widespread use for over 60 years. Several observational studies over the years showed that HRT use by younger postmenopausal women was associated with a significant reduction in total mortality; available evidence supported the routine use of HRT to increase... view more...

Lung scintigraphy more reliable than CTA in excluding pulmonary embolism in pregnant patients
A medical imaging procedure known as lung scintigraphy may be more reliable than pulmonary CT angiography (CTA) for identifying or excluding pulmonary embolism (PE) in pregnant patients.   view more (2009-10-21)

Clots traveling from lower veins may not be the cause of pulmonary embolism in trauma patients
A report from a team of Massachusetts General Hospital (MGH) physicians calls into question the longstanding belief that pulmonary embolism (PE) - the life-threatening blockage of a major blood vessel in the lungs - is caused in trauma patients by a blood clot traveling from vessels deep within the legs or lower torso.   view more (2009-10-20)

Blood clots in lungs might not always originate in deep veins of legs and pelvis in trauma patients
Few trauma patients who develop potentially deadly blood clots in the lungs (pulmonary embolism) also have clots in the deep veins of their pelvis and legs (deep venous thrombosis), challenging commonly held beliefs about the association between the two conditions.   view more (2009-10-20)

U-M researchers find those with severe H1N1 at risk for pulmonary emboli
University of Michigan researchers have found that patients with severe cases of the H1N1 virus are at risk for developing severe complications, including pulmonary emboli, according to a study published today in the American Journal of Roentgenology.   view more (2009-10-15)

CT scans show patients with severe cases of H1N1 are at risk for developing acute pulmonary emboli
Researchers utilizing computed tomography (CT) scans have found that patients with severe cases of the H1N1 virus are at risk for developing severe complications, including pulmonary emboli (PE).   view more (2009-10-14)

Combination of PET/CT tests can expedite diagnosis of lung cancer in a fast-track setting
Research published in the October 2009 issue of the Journal of Thoracic Oncology has found an effective combination of positron emission tomography (PET)/computed tomography (CT) (PET/CT) tests to diagnose lung cancer in a "fast-tracked" outpatient setting.   view more (2009-10-01)

Study finds nontuberculous mycobacteria lung disease on the rise in the United States
Nontuberculous mycobacteria (NTM) are environmental organisms found in both water and soil that can cause severe pulmonary (lung) disease in humans. Pulmonary NTM is on the rise in the United States, according to a large study of people hospitalized with the condition.   view more (2009-09-25)

New test quickly ID's active TB in smear-negative patients
Active tuberculosis can be rapidly identified in patients with negative sputum tests by a new method, according to European researchers. Active tuberculosis (TB) is the seventh-leading cause of death worldwide, and while the diagnosis of active TB can be rapidly established when the bacteria can be identified on sputum microscopy, in about half of... view more...

UT scientists discover link between protein and lung disease
In a development that could lead to a novel approach to the treatment of a devastating lung disease, biochemists at The University of Texas Health Science Center at Houston report they are the first to link the osteopontin (OPN) protein to chronic obstructive pulmonary disease (COPD).   view more (2009-09-16)

Endothelin-Related Drugs Benefit Patients With Pulmonary Hypertension
