Cardiogenic shock heart failure need advice please

My husband was diagnosed with cardiomyopathy and ischaemic heart disease about 10 years ago. He was put on 2 types of fluid tablets along with heart medications. In February this year I talked him I to seeing his doctor because his breathing was bad along with a constant cough and vomiting his doctor sent him straight to the ED. During the 8 hours he suffered numerous hypoglycaemic episodes along with BP dropping down dangerously low along with his heart beat slowing down very low. He said to me I don't feel good I said what do you mean then he went out to it. His machines started beeping a nurse came running in the called Code Blue. A doctor rushed to me and asked do we have permission to resuscitate him I said of course yes. They got his heart going again he was transferred to resuss unit then to ICU then a week later to the ward. They increased his fluid tabs and he lost just over 18 kilos whilst in hospital from all the fluid in his feet legs around his heart and in and around his lungs. He was diagnosed with cardiogenic shock whilst in hospital. He looked so much better after losing all the fluid. Since coming home from hospital he had the chronic heart failure nurses coming out weekly to check on him but he refused to do anything they said. Example he was restricted to 2 litres of all types of fluid per day but he was having 3 to 4 litres per day they told him no more than 2 litres of any type of fluid per day, now he can have anywhere from 5 to 7 litres per day. His stomach is clearly enlarged yet again he won't show me his legs or feet nor will he go see his doctor monthly like he was told nor attend his hospital appts either. His breathing is bad again and his constant coughing is very bad as is his vomitting. He was told by the chronic heart failure nurses it's not a case of if it's a case of when you will end up back in hospital because you will and next time you may not be so lucky to be revived it may be too late. We have all tried talking to him but he keeps saying I am fine even when we talk about his breathing his coughing and vomiting he replies I'm fine. He refuses to go to his doctor or talk to him over the phone. My neighbour spoke to me yesterday out of concerned as they have heard his constant coughing and vomitting at all hours of the day and night during the night it wakes them up as ut does myself and my adult children living at home. All the family have tried talking to him to coerce him to go see his doctor but he keeps saying I'm fine we say clearly you are not just listen to your breathing your constant coughing and vomitting. I'm so afraid one day I'm going to come home or walk into his bedroom and find him deceased which I don't want to happen. Has anyone else dealt with this either with themselves or a family member and managed to get them to see their doctor. Seriously he needs to see his doctor before it's too late not just for him but for all our family. Any help or advice would be much appreciated.
