For Heart Health -- Seeing Is Believing
From VOA Learning English, this is the Health & Lifestyle report.
When it comes to having a healthy body, seeing may be believing.
Experiments suggest that people who see detailed pictures of their clogged arteries may be more likely to stay healthy than people who do not.
The latest experiment was done in Sweden.
Researchers there studied just over 3,500 people. These individuals were between 40 and 60 years of age. Each person had at least one risk factor for heart disease, but no signs of the disorder.
The researchers divided these subjects into two groups.
One group received what was called usual care – like taking medicine or talking with health care workers about heart disease.
However, the members of the other group got to see pictures of their arteries. Researchers also gave them personalized guidance on why those pictures might be a sign of future health problems.
One year later, the people who saw the images of their own arteries had fewer risk factors for heart disease than those who did not see pictures.
The researchers reported their findings in The Lancet.
The lead writer of a report on the study was Ulf Naslund of Umea University. In an email to the Reuters news agency, he explained that the best ways to keep your arteries healthy is to follow a healthy lifestyle. He said that means do not smoke, drink less alcohol, eat healthy food, exercise and take the right medications to lower cholesterol and high blood pressure.
There are plenty of treatments, Naslund noted. That is not the problem. The problem, he said, is that people do not take steps to improve their condition or take their medicines.
That is where the "seeing" part may help.
Doctors warn that many people think they have healthy hearts but, actually, they do not.
Atherosclerosis, or hardening of the arteries, can be a silent killer. It takes many years to develop and patients may show no symptoms until the condition is severe and difficult to treat.
Because it is a silent killer, experts say patients only remember a small part of what their doctor tells them to do. Seeing a picture is much more effective. To use a popular English expression, "A picture is worth a thousand words."
Each year around the world, about 17.9 million people die from some form of cardiovascular disease. That is 31% of all deaths worldwide. These numbers come from the World Health Organization (WHO).
Cardiovascular diseases (CVDs) are disorders of the heart and blood vessels. The WHO website published this advice about heart health:
Tobacco use, an unhealthy diet, and physical inactivity increase the risk of heart attacks and strokes.
Exercising for at least 30 minutes every day of the week will help to prevent heart attacks and strokes.
Eating at least five servings of fruit and vegetables a day, and limiting your salt intake to less than one teaspoon a day, also helps to prevent heart attacks and strokes.
And that's the Health & Lifestyle report.

研究人员对3500多人进行了研究 。这些人的年龄在40到60岁之间 。每个人都至少有一项患心脏病的危险因素，但是没有这种疾病的迹象 。
然而，另一组受试者看到了自己动脉的图片 。研究人员还为他们提供了个性化指导，向他们解释了这些图片可能是未来健康问题的征兆的原因 。
该研究报告的首席作者是 瑞典于默奥大学的纳斯隆德（Ulf Naslund） 。在给路透社的一封电子邮件中，他解释称，保持动脉健康的最佳途径是遵循健康的生活方式 。他说，这意味着不要吸烟，少饮酒，饮食健康，勤锻炼，服用对症的药物来降低胆固醇和高血压 。
纳斯隆德指出，治疗方法有很多 。但是这不是问题所在 。他说，问题是人们没有采取措施改善自身的状况，也没有服药 。
动脉粥样硬化（动脉硬化）可能是一个无形的杀手 。它会潜伏多年而且病人可能没出现任何症状，直到病情严重甚至药石无医 。
专家指出，因为动脉硬化是一个无形的杀手，因此病人只记得医生嘱咐的小部分内容 。而看图像的效果更加强烈 。用一句流行的谚语来表达，“百闻不如一见” 。
全球每年约有1790万人死于某种形式的心血管疾病 。这占全球死亡人数的31% 。这些数据来源于世界卫生组织（WHO） 。
