BANGKOK - King Bhumibol Adulyadej of Thailand, the world's longest-reigning monarch, is recovering after undergoing an operation to open narrowed coronary arteries, according to the Bureau of the Royal Household.
Bhumibol, 88, underwent an operation on Jun. 7 at Siriraj hospital in Bangkok where he has spent the most part of the past nine years hospitalized, according to a statement released last night.
"His Majesty the King's heart has shown signs of improvement after Tuesday's treatment of the monarch's narrowed coronary arteries. The King's heartbeat, breathing and blood pressure were normal," the Royal Household said.
Electrocardiograms and blood tests showed that the heart's function has improved satisfactorily at the discretion of the doctors attending him, added the note.
Last week the Royal House said the monarch recovered "satisfactorily" after being treated for cardiac complications detected the previous week.
On June 9, Thailand celebrated the 70th anniversary of the coronation of Bhumibol, considered a semi-divine being, the symbol of unity and the guide of the nation.
The health status of Bhumibol, who has not been seen in public since January, is a taboo subject in the country because of the lese majeste law, which shields the monarchy from all kinds of accusations and comments.
Since the military junta took power after a coup in May 2014, the amount of cases related to this law has multiplied.
