The diagnostic criteria for hypertension are 140 or higher systolic blood pressure in Japan, but a study by a group such as the University of Tokyo analyzed data on more than 2 million people and found that even lower values increased the risk of heart failure. We announced the results.
This research was published in an overseas academic journal by a group of specially appointed lecturers Hidehiro Kaneko, Department of Cardiology, The University of Tokyo Hospital.
In Japan, the standard for diagnosing hypertension and starting treatment is 140 or higher for systolic blood pressure or 90 or higher for diastolic blood pressure, but in the United States, it is more stringent, 130 or higher and 80 or higher, respectively.
According to a detailed analysis of data from the health examinations of more than 2.19 million people in Japan, those with a systolic blood pressure of 130 or a diastolic blood pressure of 80 are at risk of heart failure compared to those with lower blood pressure. Was 1.3 times higher and the risk of atrial fibrillation was 1.2 times higher.
According to the guidelines of the Japanese Society of Hypertension, the range of normal blood pressure is less than 130 systolic blood pressure and less than 80 diastolic blood pressure. It has been confirmed that the risk of illness is increasing.
Kaneko said, "I was able to show the possibility that controlling blood pressure is important in the prevention and treatment of illness. I want many people to be aware of the importance of blood pressure." I will.
