The tests that are commonly performed to diagnose PAH
and rule out other diseases are blood tests, pulmonary function tests, X-rays of the chest, electrocardiography (ECG), and the "6-minute walk test", which essentially measures how far an individual can walk in that time period.
The concentration of 16 PAHs
detected and their total PAH
) are presented in Table 1.
The prevalence of critically ill elderly patients with PAH
India has previously produced its data on PAH
concentration to study the carcinogenic effects through the samples obtained from the atmospheres of urbanized areas in Lucknow (Bhargava et al.
It found some PAHs
in coal tar sealcoats that were 30 times more toxic than one of the most common PAH
compounds that was studied previously in these products by the U.
The study was recently published in the New England Journal of Medicine and showed that the combination of ambrisentan and tadalafil reduced the risk of clinical failure by 50% in treatment-naive PAH
patients compared to pooled ambrisentan and tadalafil monotherapy (p=

worsens over time and is life-threatening because the pressure in a patient's pulmonary arteries rises to dangerously high levels, putting a strain on the heart.
N Galie from Bologna University, Italy, is chairman of the European Guideline Committee on PAH
and guest editor of the Journal of the American College of Cardiology supplement on the Proceedings of the 5 th World Society of Pulmonary Hypertension.
Researchers at the Columbia Center for Children's Environmental Health at the Mailman School of Public Health followed 233 nonsmoking pregnant women and their children in New York City from pregnancy into childhood, and found that children born to mothers exposed to high levels of PAH
during pregnancy had five times the odds of a higher-than-usual number and degree of symptoms that characterize ADHD -- specifically inattentive-type ADHD at age 9 -- compared with children whose mothers did not have high PAH
Many areas in the city of nearly 18 million people have high concentrations of toxic PAHs
posing major health risks, a Central Pollution Control Board ( CPCB) study found.
Yet, population studies have found that PAH
exposure through cooked meats also has been associated with cancer in humans.
