WASHINGTON - President Bush has requested billions more to prepare for potential disasters such as a biological attack or an influenza epidemic, but his proposed budget for next year would zero out popular health projects that supporters say target more mundane, but more certain, killers.

If enacted, the 2007 budget would eliminate federal programs that support inner-city Indian health clinics, defibrillators in rural areas, an educational campaign about Alzheimer's disease, traumatic brain-injury centers, and a nationwide registry for Lou Gehrig's disease. It would cut close to $1 billion in health care grants to states and would kill the entire budget of the Christopher and Dana Reeve Paralysis Resource Center.

In a $2.8 trillion budget, the amounts involved may seem minuscule, but proponents argue that the health care projects Bush has singled out are the "ultimate homeland security," as Vinay Nadkarni put it. The spokesman for the American Heart Association said he cannot fathom why the administration has recommended eliminating a $1.5 million program that provides defibrillators to rural communities and trains local personnel on how to use the machines to restart hearts that go into cardiac arrest.

"Coronary heart disease is the number one killer in the United States," Nadkarni said. "This is actually something we can arm ourselves with."

To meet his twin goals of taming a rising deficit and increasing spending on national security, Bush proposed $2.2 billion in cuts to discretionary programs elsewhere in the budget. The Department of Health and Human Services would absorb $1.5 billion of that total, in part to direct more money to mandatory programs such as Medicare.

"We had to make hard choices, hard choices about very well-intentioned programs," said HHS Secretary Mike Leavitt.

Sen. Edward M. Kennedy, D-Mass., said the administration chose "tax cuts for the wealthy and giveaways for the drug industry" over services for needier patients.

Some of the proposed cuts are familiar Bush targets that in previous years were rescued by congressional backers. Others are new and could be harder to restore this year. Leavitt said his team slashed programs that were duplicative or underperforming. But in every case, physicians, patient advocates and policy analysts argue, it will cost taxpayers more in the long run.

The 2007 budget would terminate $12 million in state grants for community-based Alzheimer's care and a $1.6 million "Maintain Your Brain" campaign run out of the Centers for Disease Control and Prevention. Today, more than 4.5 million Americans have Alzheimer's, a number expected to rise to 16 million by mid-century, said Stephen McConnell, vice president for public policy at the Alzheimer's Association.
