Last Sunday, the 80-year-old Empress was diagnosed with myocardial ischemia, a condition common in the elderly or those under significant stress. Since late June, the Empress has experienced chest pains that have increased over time. The pains grew in frequency, from a few times per week to occurring several times each day. This heart condition occurs when heart vessels are temporarily blocked. If not treated, the patient can suffer a heart attack. Those who receive this diagnosis are advised to refrain from activities that can raise their heart rates and stress levels.
An electrocardiogram performed last month on the elderly Empress revealed evidence of possible heart disease. Doctors decided on a more thorough examination and tests conducted. At the University of Tokyo Hospital, she underwent a coronary computed tomography scan. The results found she was suffering from inadequate blood flow to parts of her heart muscle through the coronary arteries. The scan showed narrowing of two of the three coronary arteries. However, officials say these results are unrelated to her chest pains.
Her condition isn’t severe enough to warrant surgery. If her symptoms worsen, she will be given medication. In 2011, the Emperor was experiencing similar symptoms. The following year, bypass surgery was performed after his diagnosis of angina.
