When Korean hypertensive patients were followed up for 20 years안전놀이터, it was found that nearly half of them failed to manage their blood pressure below the target blood pressure (140/90 mmHg). However, it was confirmed that those who managed to keep their blood pressure below the target blood pressure reduced their risk of cardiovascular and cerebrovascular diseases by up to about 60%.
Korea University Guro Hospital Cardiovascular Center Professor Na Seung-un, Department of Pathology Department Chief Engineer Jeong-Bun Kim, Korea University Cardiovascular Research Institute Professor Choi Byung-Geol, Institute of Health Sciences Research Institute Professor Min-Woo Lee Data from 38,000 adults over the age of 18 registered in the Korea Centers for Disease Control and Prevention-National Health and Nutrition Examination Survey was analyzed.
As a result, when the history of hypertension lasted more than 20 years, 12.2% of hypertensive patients had stroke, 14.6% of ischemic heart disease, 5% of myocardial infarction, and 10.6% of angina pectoris. This statistic includes all patients who received appropriate antihypertensive medication. The average age of hypertensive patients in Korea is 55.86 years old, and considering that the life expectancy of the Korean population is 83.5 years (OECD Health Statistics 2022), it is possible to manage hypertension for about 30 years, which is 10 years longer than 20 years assuming that people survive to the expected life expectancy . Should be.

The reason why more patients had complications than expected is that, unlike treatment, only a few people were managed below the target blood pressure. Professor Seung-Woon Na said, “It was counted that less than two-thirds of all hypertensive patients achieved blood pressure levels below the target blood pressure.” “he said.
Fortunately, it has been confirmed that managing blood pressure below the target blood pressure dramatically reduces the possibility of cardiovascular disease. The risk of stroke was reduced by 37.2%, ischemic heart disease by 27.7%, myocardial infarction by 30.7%, and angina by 29.4%. Professor Seung-Woon Na said, “If hypertensive patients manage their blood pressure, the accompanying risk factors such as dyslipidemia and metabolic diseases are also improved. Therefore, it is estimated that the actual risk of developing cardiovascular disease will be further reduced if the blood pressure is managed below the target blood pressure.” Taking this into account, the analysis showed that the risk of stroke was reduced by 59.2%, ischemic heart disease by 58.6%, myocardial infarction by 55.2%, and angina by 60.1%.”

As a result of analyzing the group that did not control target blood pressure well, ▲anemia ▲stroke experience ▲older male ▲diabetes ▲standard range of body mass index (18-24) were identified as major predictors of failure to achieve target blood pressure. Professor Seung-Woon Na said, “Surprisingly, there were many cases where people with a normal body mass index failed to achieve target blood pressure. This is presumed to be due to relatively complacent management.” You have to be more careful to lower your blood pressure.”
It seems that hypertension management should be different according to gender. Males were diagnosed with hypertension earlier than females and had a higher overall prevalence rate, but it was confirmed that the average increase was 1.77 times for men and 2.74 times for women every 10 years. After the age of 60, the prevalence of women outpaced men. Professor Choi Byung-geol said, “This study also confirmed differences in the prevalence of elderly hypertensive patients according to gender. did.
Meanwhile, the results of this study were published in the latest issue of ‘Global Heart’, an international journal of the World Heart Foundation.
