[Headlines] (HL-의학/건강/운동) US Changes Definition for High Blood Pressure
최고관리자  |  17-11-26 01:00

Recently, two leading heart organizations changed the definition of what it means to have high blood pressure. Because of this change, the number of Americans with high blood pressure jumped from 32 percent to 46 percent. Doctors at the American Heart Association and the American College of Cardiology now classify anyone with a blood pressure reading of 130 over 80 as having high blood pressure. Before, the cutoffs for high blood pressure had been a top number of 140 and a lower number of 90. Health experts at the website Science Daily say blood pressure is defined by two numbers. The top number, called systolic, represents the force with which your heart pumps blood into the blood vessels. The bottom, called diastolic, is a measure of the resistance to the blood flow in the body's blood vessels.
* leading = 선두적인, 가장 중요한/ definition = 정의, 의미/ high blood pressure = 고혈압(hypertension)/ cardiology = 심장(병)학/ classify = 분류[구분]하다/ reading = (계기에 나타난) 지시 눈금값[측정값]/ cutoff = 한계; 마감, 기한/ systolic = 심장수축기성(心臟收縮期性)의/ represent = 나타내다, 상징하다 pump A into B = B에 A를 주입시키다[쏟아 붓다]/ blood vessel = 혈관/ diastolic = 심장 확장(기)의/ resistance to ~ = ~에 대한 저항(력)/ blood flow = 혈류(량)(血流量)      

The American Heart Association says the new guidelines are designed to help people take steps to control their blood pressure earlier. High blood pressure can cause heart disease and stroke – the two leading causes of death in the world.
* be designed to ~ = ~하도록 제작되다/ take stepts = 조치를 취하다/ heart disease and stroke = 심장질환과 뇌졸증

The new guidelines set blood pressures in these categories:

* Normal Blood Pressure: Under 120 over 80
* Elevated Blood Pressure: Top number 120-129 and bottom number less than 80
* High Blood Pressure / Stage 1: Top number of 130-139 or bottom number 80-89
* High Blood Pressure / Stage 2: Top number at least 140 or bottom number at least 90

A 2016 study by the World Health Organization and hundreds of scientists found that the number of people in the world with high blood pressure had reached 1.13 billion. However, the study defined high blood pressure as 140 over 90. Should they adopt the new guidelines, the number of people with high blood pressure worldwide will most likely increase.
* at least = 적어도[최소한]/ adopt = (특정한 방식이나 자세를) 쓰다[취하다]
