四级阅读原文翻译：木乃伊曾患心脏病研究人员表示，他们在3500年前的古埃及木乃伊身上发现了动脉硬化的证据，驳斥了人们长期以来的一种观点，即心血管疾病基本上是现代社会才有的。一个由心脏成像专家和埃及古树学者组成的团队用CT设备对来自开罗埃及古物国家博物馆的22具木乃伊进行了检查，寻找指示肌体患有心血管疾病的钙沉积现象。他们在16具木乃伊身上辨别出了心脏或动脉，也有的两者都得到了确认。其中9具存在心血管的钙化现象。一份分析报告称，这些钙化是动脉硬化症的明确或可能证据，动脉硬化会导致心脏病和中风。负责此次调查的加州大学心脏病及成像技术专家格里高里·托马斯说，不止我们现代人有动脉硬化症，这种病早在3500年前就很常见了;它一直是人类健康状况的组成部分。本周二在美国心脏协会召开的会议上通报了此次调查。定于周三出版的美国医学协会期刊上将刊登相关研究报告。心脏病是人类的头号杀手，而且它在、印度及拉丁美洲等发展家越来越常见。心脏病发病率攀升的现象往往被归咎于城市化、快餐饮食、吸烟以及久坐不动等西式生活方式。在8具死亡时年龄大于等于45岁的木乃伊身上，有7具发现了动脉硬化的迹象，剩下8具年龄不足45岁的木乃伊也有2具有此病征。那么病因何在呢?研究人员目前尚不确定。但是他们指出，这些木乃伊生前都是埃及社会上层人士，他们的饮食包括牛肉、鸭肉和鹅肉。此外，由于没有冰箱为食物保鲜，保存鱼类和肉食的办法往往是盐渍，加大了这些埃及人罹患高血压的可能性。通过CT扫描无法得知这些法老们中有谁生前肥胖，不过，在那个年代他们肯定是不抽烟的。

研究人员也无法确定这些法老当中是否有人真正死于心血管疾病。四级阅读句型讲解：
