Thaksin to stay in hospital as tests show no uptickThaksin: Heart and lung problemsFormer prime minister Thaksin Shinawatra's condition has not improved since he was transferred to the Police General Hospital for treatment. Pol Lt Gen Dr Sophonrat Singhajaru, the hospital's chief physician, said on Friday an echocardiogram and lung tests showed Thaksin's heart and lung conditions were still a concern, while his blood pressure remains stable. Details of Thaksin's treatment cannot be disclosed due to patient privacy laws, said Pol Lt Gen Dr Sophonrat. Pol Lt Gen Achayon Kraithong, Royal Thai Police spokesperson, told the media that security arrangements for visits have not yet been discussed. Asked if Thaksin might be sent to a private hospital, Mr Wissanu said there was no reason to do so.
