研究人员发现，当人们听到自己喜爱的音乐时，血管就会像发笑或是服用治疗血管疾病的药物时那样扩张。位于巴尔的摩的马里兰大学医学中心预防心脏病学主任医师迈克尔访桌账担骸把苤本独┐罅耍┱欧浅Ｃ飨浴Ｔ谄渌疃心阋部梢钥吹窖芾┱牛热缍土渡硖濉！狈盟±嘁┪锘蜓芾┱潘刈幻敢种萍恋纫┪锸币不岢鱿掷嗨菩Ч?

    米勒说：“我们不是让你停止服用他汀类药物，也不是让你停止锻炼。我们只是想在心脏健康领域补上这么一条。”

    他率领的小组检测了１０位身体健康、无吸烟习惯的男性和女性。这些人按要求带来了自己喜爱的音乐。他们先花半个小时的时间去听这些音乐，再用半个小时的时间去听让他们感到紧张不安的音乐，与此同时研究人员对他们进行超声波测试，观察血管的活动。

    米勒说，与正常情况相比，当这些志愿者听到自己喜爱的音乐时，血管直径平均扩大２６％。听到他们厌恶的音乐时——在这组志愿者中多为重金属音乐——血管变细６％。 

Music to your ears can be music for your heart, too

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

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

    They found that when people listened to their favorite music, their blood vessels dilated in much the same way as when laughing, or taking blood medications.

    "We have a pretty impressive effect," said Dr Michael Miller, director of preventive cardiology 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 and ACE inhibitors.

    When blood vessels open more, blood flows more smoothly and is less likely to form. the blood clots that cause heart attacks and strokes. Elastic vessels also resist the hardening activity of atherosclerosis.

    "We are not saying to stop your statins or not to exercise but 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 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 - narrowed blood vessels by six percent, Miller said.

    Miller said he came up with the idea after discovering the 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 real good," he said.

    Most of the volunteers chose country music but Miller said the style. is not so important as what pleases each individual.     (Agencies)
