[Article] Empress diagnosed with myocardial ischemia but no surgery needed

Empress Michiko was diagnosed with myocardial ischemia Sunday at a Tokyo hospital after complaining of chest pain in recent months, the Imperial Household Agency said.
The 80-year-old wife of Emperor Akihito underwent a coronary computed tomography scan at the University of Tokyo Hospital and was found to be suffering from insufficient blood flow to some parts of the heart muscle via the coronary arteries, the agency said.
While no surgery is needed for the moment, she may be given medication if her symptoms worsen, it said.
The empress has experienced chest pain since late June. She initially experienced pain several times a week, but the frequency has increased recently to several times a day, according to the agency.
Last month an electrocardiogram showed evidence of possible heart disease, prompting the agency to arrange for the empress to undergo a more detailed exam.
In myocardial ischemia, obstruction of a blood vessel can occur temporarily due to stress or simply advancing age. But it also could be evidence of more serious heart disease.
Emperor Akihito showed similar symptoms in 2011. He underwent heart bypass surgery in 2012 after being diagnosed as suffering from angina.
