上皇じょうこうさま退院たいいん 「無む症候しょうこう性せい心筋しんきん虚うろ血ち」と診断しんだんで新あらたな薬物やくぶつ治療ちりょうへ

Emperor Emeritus, who had been hospitalized at a hospital in Tokyo for a detailed heart examination, was discharged on the morning of the 10th.

Although there are no subjective symptoms, it was diagnosed that when a certain level of physical exertion is exceeded, blood flow to the heart muscle becomes insufficient. Therefore, a new medication to improve blood flow will be taken, and you will spend your time avoiding excessive physical exertion.

The 91-year-old Emperor Emeritus was diagnosed during regular checkups and follow-up examinations as likely having myocardial ischemia, a condition in which blood flow from the coronary arteries surrounding the heart to the heart muscle is insufficient. To undergo more detailed tests, he was admitted to the University of Tokyo Hospital in Bunkyo Ward, Tokyo, from May 6. However, he was discharged on the morning of the 10th and returned by car to his residence in the Akasaka Estate in Minato Ward, together with the Empress Emerita, who had been visiting him every day.

According to the Imperial Household Agency, as a result of a coronary artery CT scan and other tests, it was diagnosed as asymptomatic myocardial ischemia, in which, despite having no subjective symptoms such as chest pain, blood flow from the coronary arteries to the heart muscle becomes insufficient when a certain level of physical exertion is applied.

In 2012, at the age of 78, the Emperor Emeritus was diagnosed with angina and underwent coronary artery bypass surgery. Three years ago, he was also diagnosed with right-sided heart failure and has since continued internal medical treatment such as taking medication and restricting fluid intake.

As you age and your arteriosclerosis progresses, it is necessary to have more careful follow-up by your physician than before. Going forward, you will start taking new medication to improve blood flow in your coronary arteries, and you are advised to avoid excessive physical exertion in your daily life.

On the other hand, since maintaining muscle strength to prevent falls and walking difficulties is also important, it means reconsidering everyday activities such as taking morning and evening walks or going up and down stairs.

Asymptomatic myocardial ischemia is a condition in which blood flow in the coronary arteries, the vessels surrounding the heart, is reduced, resulting in insufficient oxygen supply to the heart muscle. The key characteristic of this condition is that it does not cause symptoms such as chest pain.

It occurs when arteriosclerosis progresses and the inside of the coronary arteries becomes narrowed, but since there is no chest pain or other symptoms, it is often not discovered until the disease has advanced.

Treatment involves first confirming the location and number of narrowed areas in the coronary arteries, then choosing between medication to prevent blockage, using a catheter to widen the artery, or performing bypass surgery to reroute blood flow around the obstructed area.
