what is hypertension (disease or medical condition) diagnose pathophysiology

It is said that there are quite a lot of people who have been left as it is, although they said that their blood pressure is a little higher in health checkups. However, recent research and research has shown that high blood pressure increases the risk of myocardial infarction and stroke.
<Current high blood pressure standards>
Normal blood pressure
Maximum blood pressure less than 130 and minimum blood pressure less than 85
Normal high blood pressure
Maximum blood pressure 130-139, or minimum blood pressure 85-89
High blood pressure
Maximum blood pressure 140 or higher, or minimum blood pressure 90 or higher
In contrast, in the United States, the review of high blood pressure standards has begun.
According to the 7th guideline of the US Joint Committee on Hypertension reported in May 2003, “high blood pressure 120-139 or minimum blood pressure 80-89” is defined as prehypertension. In other words, the standards for high blood pressure are strict, and people who have “high blood pressure” need some kind of measures (treatment and guidance for improving their lives) 

 The US Cardiopulmonary Blood Research Institute also has a high blood pressure reserve in the range of “maximum blood pressure 120-139, minimum blood pressure 80-89” and it is necessary to control blood pressure by diet and exercise. High blood pressure is the greatest risk of myocardial infarction
There are currently 34 million people with high blood pressure in need of treatment in Japan. In particular, at age 30 and over, 51.7% of men and 39.7% of women are estimated to have high blood pressure.
The fear of high blood pressure is that one day, a person may suddenly have a stroke of myocardial infarction or stroke, despite having few subjective symptoms. The risk factors for myocardial infarction and stroke have traditionally been “hypertension, smoking, diabetes, hyperlipidemia”, and recent studies have shown that hypertension is the greatest risk. For example, in the case of myocardial infarction, the risk of a person with high blood pressure is about 4.8 times that of a person with normal blood pressure (* 2).
Therefore, in Japan, the main theme is how to control blood pressure at the stage of “high blood pressure” prior to myocardial infarction or stroke.
(* 2) According to Kumamoto University's survey of 1000 patients with acute myocardial infarction, the highest risk is high blood pressure, smoking, diabetes, and high cholesterol.

The main cause of high blood pressure is diet
A review of the causes of high blood pressure has also begun. The causes of high blood pressure can be broadly divided into “inheritance” and “lifestyle”. Traditionally, these two influences have been halved.
Recently, however, the influence of lifestyle habits has been set at 60%. Lifestyle is more likely to cause high blood pressure than genetic factors such as the constitution inherited from parents.
Among the lifestyle habits, diet is particularly important. In relation to high blood pressure, the influence of excessive salt intake has been pointed out for some time. This is because salt has the effect of increasing blood pressure in the body.
In addition, the effects of obesity have recently attracted attention, and overeating (calorie over) has been highlighted as a cause of high blood pressure. It has been found that when obesity progresses by eating too much, a hormone called leptin accumulates in fat cells, which increases blood pressure

Therefore, taking too much salt and preventing excess calories are the two pillars of preventing and improving high blood pressure in the diet.
 Leptin is a typical hormone derived from mast cells and has a function to control appetite. Recent studies have shown that leptin is associated with obesity as well as many other diseases such as hypertension and osteoporosis.
