My dad that just passed away 1 month ago had respiratory problem and coughing everyday for about 2 years. His oxygen was almost always good along with his blood sugar check daily. BP is pretty stable. Recently about 8 months ago he had been coughing up small amount of blood in mucous at times. Then gradually small droplets of blood found on the floor. Xray scan were normal. Pulmonary doctor was not that concernand only prescribe regular med. 22 days before he passed away, I took him to the ER to get check up because more blood was coming out. CT scan, xray, lab was nothing special. They wanted to admit him for monitor for possible TB. He left AMA in the ER because he doesnt want to be isolated for possible TB again. They also told me that he was supposed to see an infectious disease doc a year ago after discharge. When he was discharged a year ago, no one told us that or wrote it down? Last month he was unconcious on the floor pulseless. Mom called 911 right away. CPR was not effective. Autopsy shown cause of death "severe coronary artery disease" secondary to "cardiomegaly" with onset of symptoms "years" HOW???? The whole time he was having lung problem. There was no DX of any heart condition. What happen to the recent xray did they not see that his heart was larger than normal? I am still puzzled. I just need closure. My family already accepted it but his cause of death has always been on my mind ever day. I was thinking of calling the hospital for explanation but how go about from there? -I'm a new LVN.
