According to the Prison Law of People's Republic of China (PRC), criminals suffering from serious diseases who need medical treatment on parole, and pregnant or breast-feeding women are not allowed to be imprisoned.
Heart stent is a kind of medical instrument used to treat heart diseases. It is usually placed in the coronary artery to help improve the blood supply to the heart and relieve the symptoms of myocardial ischemia. However, this does not mean that criminals with serious diseases need to be released on bail for medical treatment. Therefore, if a prisoner is considered to meet the conditions for admission to prison, the prison can be admitted to prison according to law.
