     Songs that make our hearts happy can make them stronger too, US researchers reported on Tuesday.

     They found that when people listened to their favorite music, their blood vessels (血管) dilated in much

the same way as when they are laughing, or taking blood medications (药物).

     "We have a pretty impressive effect," said Dr Michael Miller, director of preventive cardiology (心脏病学)

at the University of Maryland Medical Center in Baltimore.

     "Blood vessel diameter improved," he said. "The vessel opened up pretty significantly. You can see the

vessels opening up with other activities such as exercise." A similar effect is seen with drugs such as statins.

     When blood vessels open up more, blood flows more smoothly and is less likely to form the clots (凝块)

that cause heart attacks and strokes. "We are not saying to stop your stations or not to exercise but rather to

add this to an overall program of heart health," said Miller, who presented his findings to a meeting of the

American Heart Association in New Orleans.

     Miller's team tested 10 healthy, non-smoking men and women, who were told to bring their favorite music.

They spent half an hour listening to the recordings and half an hour listening to music they said made them feel

anxious while the researchers did ultrasound (超声波) tests designed to show blood vessel function.

     Compared to their normal baseline measurements, blood vessel diameter increased 26 percent on average

when the volunteers heard their joyful music. Listening to music they disliked-in most cases in this group heavy

metal-blood vessels narrowed by six percent, Miller said.

     Miller said he came up with the idea after discovering that laughter caused blood to literally flow more

smoothly. "I asked myself what other things make us feel real good, besides calories from dark chocolate of

course. Music came to mind.... It makes me feel really good," he said.

     Most of the volunteers chose country music but Miller said the style is not so important rather than what

pleases each individual.
