Heart Attack Season Is Here

WASHINGTON - Those lords-a-leaping and ladies dancing might want to consider the downside of the holidays: Heart attack season has arrived.

December and January are the deadliest months for heart disease, and many of the things that make the season merry are culprits: Rich meals, more alcohol - and all that extra stress.

But what may make the Christmas coronary more deadly than the same-size heart attack in, say, August, is a double dose of denial. It's not uncommon for people to initially shrug off chest pain as indigestion. Research suggests they're even more reluctant for a run to the emergency room when it means disrupting a holiday gathering, or if they've traveled to a strange city - meaning they arrive sicker.

Minutes matter.

"You have only a short window of opportunity to save heart muscle," warns William Suddath of Washington Hospital Center in the nation's capital, where a cardiac team on duty 24 hours a day aims to start clearing victims' clogged arteries within 15 minutes of their arrival in the emergency room.

Vanderbilt University cardiologist Keith Churchwell says a "hurricane of factors" can tip someone at risk of a heart attack over the edge during this busy time of year.

Consider:

•Busy revelers tend to skip their medications, forget them when traveling or be unable to get refills far from home.

•What dieter can resist holiday goodies? The few extra pounds so many people gain will haunt you long-term. Right away, a particularly heavy meal, especially a high-fat one, stresses the heart as it is digested. Blood pressure and heart rate increase. There's even evidence that the lining of arteries becomes temporarily more clot-prone.

•Too much salt has an even more immediate effect, causing fluid retention that in turn makes the heart have to pump harder.

•Alcohol in moderation is considered heart-healthy. But if a round of holiday parties leaves you tipsy, that, too, makes your heart pump harder to get blood to peripheral arteries.

•Worse is something called "holiday heart syndrome," where alcohol literally irritates the heart muscle to trigger an irregular heartbeat called atrial fibrillation. If a-fib goes unchecked for too long, it in turn can cause a stroke.

•People say they're too busy to exercise, especially as it gets cold and darkness falls earlier.
