【medical-news】空气污染可能与心脏病人的ST段下移
In continuing coverage from yesterday's edition of CV News Digest, HeartWire (9/9, O'Riordan) reported that "there is an increased risk of ST-segment depression among cardiac patients exposed to pollution," according to a study published in the journal Circulation.
Researchers "collected data on 48 patients from the Boston area with coronary artery disease," HealthDay (9/9, Reinberg) added. The investigators "monitored the patients for 24 hours using portable electrocardiograph machines looking for changes in...ST-segment depression." The researchers "looked at the average 24-hour levels for all pollutants in Boston. They found that these levels were below accepted or proposed National Air Quality Standard thresholds." According to the investigators, "increased levels of a pollutant called PM 2.5 and black carbon...was associated with an increase in ST-segment depression." Meanwhile, "sulfur dioxide...was also associated with an increase in ST-segment depression." The researchers said that "increases in ST-segment depression were particularly higher in patients recovering from a heart attack." The study's lead researcher said that, "for patients who have just been discharged from hospital after a heart attack, guidelines from the American Heart Association and the American College of Cardiology suggest that patients should avoid heavy traffic because of the stress of driving." She added that this "study provides additional rationale to avoid or reduce heavy traffic exposure after discharge." 认领此文编译，48小时未交稿其他战友可自由认领。 Study suggests air pollution may be linked to ST-segment depression in cardiac patients.

研究人员“收集了来自波士顿地区的48位冠心病病人的数据，”研究人员“使用便携式心电图机监测病人24小时以发现ST段下降。”研究者“分析波士顿24小时内平均空气污染的级别，”发现级别低于可接受的或国家空气质量标准。根据调查，“污染物质PM2.5或炭黑的级别增加增加…和ST段下降的增加有关联。”同时，“二氧化硫…也和ST段下降增加有关，”研究人员说“ST段下降的增加，部分增加了病人的心脏病发作事件。”主要研究人员称：“刚因心脏病好转从医院出院的病人，ANA和ACC指南建议应避免交通拥挤导致的紧张驾驶。”她补充，这项“研究提供了在出院后应该避免或减少交通暴露的附加证据。” 研究显示，空气污染可能和心脏病人的ST段下降有关
