问题 Owning a cat can reduce the risk of heart attacks and strokes by more than a third, researchers have found. Scientists said that having a cat helped to relieve stress and anxiety, which is known to help protect against heart disease by lowering blood pressure and reducing the heart rate. The 10-year study looked at 4, 435 adults aged between 30 and 75 , about half of whom owned a cat. The findings, presented at a stroke conference in America, showed that 3. 4 percent of the cat owners died from a heart attack over 10 years. Among the group who had never owned a cat the rate was 5. 8 percent.
Cat owners still had a much reduced chance of developing strokes or heart attacks when researchers took account of other factors known to trigger heart disease, including high cholesterol levels, smoking and diabetes.
选项
答案研究人员发现，养猫能使患心脏病和中风的风险降低1／3以上。科研人员称，养猫有助于减轻压力、缓解焦虑情绪，从而降低血压和心律，这有助于预防心脏病。研究人员对4435名年龄在30至75岁之间的成人进行了为期lO年的调查，调查对象中约有一半人养猫。研究结果在美国的一个中风研讨会上公布时显示，在这10年里，有3．4％的养猫人士死于心脏病，而从未养过猫的人死于心脏病的比例为5．8％。研究人员还综合考虑了高胆固醇、吸烟和糖尿病等可能引发心脏病的其他一些因素，结果发现养猫人士患中风或心脏病的可能性还是要小很多。
