Living with dirty air may boost heart attack risk

NEW YORK (Reuters Health) - Fatal heart attacks may be more likely among people who spend decades living in heavily polluted areas, Swedish researchers report.

While there was no association between people's exposure to various pollutants over a 30-year period and overall heart attack risk, such exposure did appear to be associated with a greater risk of fatal heart attack, especially heart attacks occurring outside hospitals, Mats Rosenlund of the Stockholm County Council and colleagues report.The researchers also found that people who had ever lived in pollution "hot spots" with particularly dirty air had a 23 percent increased risk of heart attack, and a 40 percent increased risk of fatal heart attack.

The health effects of short-term exposure to air pollution are fairly well understood, but it is much less clear how long-term pollution exposure affects health, Rosenlund and associates point out in the journal Epidemiology.

Pollution exposure could contribute to heart attack risk by causing chronic inflammation, speeding the progression of atherosclerosis (hardening of the coronary arteries) and altering heart function, they note.

To investigate, they reviewed information on pollution exposure for 1,397 men and women living in Stockholm County who had suffered heart attacks for the first time between 1992 and 1994 and 1,870 healthy controls.

The researchers estimated carbon monoxide, sulfur dioxide, particulate matter and nitrogen dioxide exposure by linking an individuals' address to historical data on emissions and atmospheric dispersion of the pollutants.

Overall, there was no link between pollution exposure and heart attack risk. However, the risk of fatal heart attacks appeared to have some association with pollution exposure, especially among people who died outside the hospital.

This finding "implies that sudden death might be of special importance in relation to long-term air pollution exposure," Rosenlund and colleagues conclude.

US Congress urged to clear path for generic drugs

WASHINGTON - Congress should act to protect generic drugmakers from brand-name company tactics that thwart competition and keep cheaper medicines from U.S. consumers, a generic manufacturer said on Thursday.

Companies that make branded drugs are increasingly offering their own generic versions and filing frivolous petitions to block generics with regulators, Heather Bresch, senior vice president of corporate strategy at Mylan Laboratories Inc, told a Senate committee hearing. "Authorized generics are a long-term strategy designed to debilitate our industry," she said on behalf of Mylan, adding brand companies would never offer low-cost alternatives without pressure from generic competitors.

The hearing comes as health care costs in the United States continue to climb. The Senate Aging Committee's top two lawmakers said savings from more generic drugs could offer some relief, but company tactics and an underfunded Food and Drug Administration are dampening access.

Ranking Member Sen. Herb Kohl said brand companies have a right to profit, but their prices are squeezing consumers, and employers as well as state and federal budgets. "Government needs to consider action if companies unfairly or illegally manipulate the private market," said Kohl, a Wisconsin Democrat who introduced a bipartisan bill last month to prevent deals that keep generics off the market.

Committee Chairman Sen. Gordon Smith, an Oregon Republican, agreed. "Obviously we want the market to work, but it's not working when it's done that way," he said.

Hours after the hearing, three other Democratic Senators introduced related legislation baring brand name makers from offering their own generic.

Other bills aimed at fostering generics have been introduced, but it was not clear whether further action would be taken on any of them in the Senate Health, Education, Labor and Pension Committee, which handles such matters.

The Pharmaceutical Research and Manufacturers of America (PhRMA), which represents brand drugmakers, in a statement defended authorized generics as a way to boost competition.

Companies by law can seek U.S. approval for a generic before the patent expires but must show the patent is invalid or would not be infringed. The first one to win approval receives 180-days of exclusive sales.

But the Federal Trade Commission's Jon Leibowitz told lawmakers brand companies use various strategies to thwart the process, including paying generic competitors to stay off the market. He added legal complexities make it difficult for generic makers to seek relief from the courts.

"It's sort of a drug purgatory, one that results in considerable delay for consumers," said Leibowitz, an FTC commissioner who expressed support for Kohl's bill.

Stuck between the brand and generic versions lies the FDA, which has been struggling with a backlog of nearly 800 generic drug applications.

Gary Buehler, head of the FDA's Office of Generic Drugs, said the agency needed up to 100 more employees over the next three years to eliminate the build up -- a move that would cost between $16 million and $19 million a year.

"We can reduce the fat from our process but only to a certain point," he told lawmakers.

Buehler added that petitions filed by some brand companies in protest at generic applications increased the agency's workload. "Very often they're filed at the eleventh hour... and they usually raise redundant issues."

PhRMA said the petitions are a valid way to raise safety concerns and other issues.
