[|Human|] Hi, My father, aged 90, suffers angina.  He has been able to control it through taking medications and not walking far, etc.  However over the past month he has suffered a couple of attacks during night.  I know he is on the maximum medication available.  Does this mean his heart is getting worse?  He says the pain from last attacked last 2 hours., and then just disappeared.  Im worried he may be risking heart attack?  Any advice here would be good thanks..
[|AI|]  Hello thanks for posting here. Going by you description it looks like he has got unstable angina or critical coronary artery disease. Also since he is on maximum medications for the same. So next step would be ideally an intervention like angiogram followed by angioplasty or surgery. But going by his age I would advise you not to go for any intervention as it will be more of a discomfort to him. Yes, he is at the risk of having a heart attack, which you have to accept. If he was my patient I would keep hi non medical management and would adjust his doses/increase doses if necessary. Wishing him good health thank you.
