When Alma, Robin and Lisa's child gets sick with Viral TB(which is a virus I made to prove that these humanoids have a much stronger immune system than us), it starts off like the flu. She gets a sore throat minutes after breathing in the virus. She then gets nasal congestion, tonsillitis, cough, and hours later, pneumonia. Some of what she coughs up infects her digestive tract. First her esophagus gets inflamed making it hard for her to swallow. Then her stomach gets upset and she gets nausea and vomiting. Her small intestine then is not able to absorb as well as it should so she gets diarrhea and malabsorption. Then she gets appendicitis and soon after, colitis which causes her diarrhea to be painful. Later on she gets rectal inflammation also known as proctitis. Last but not least her liver enlarges. This is bad enough as it is but it gets worse. Some time later(1-2 weeks) the virus enters the bloodstream of one of her circulatory systems. But it doesn't cause vasculitis until much later(months later). Instead it floats to her heart causing chest pain, hypertrophy, and cardiomegaly. So one of her hearts gets bigger. This can cause her to be short of breath. If it weren't for granuloma formation in this illness, she would die when her heart got infected from fluid loss due to pneumonia and diarrhea. Anyway, I know that this means that she has a higher chance of getting a heart attack. However the fact that she has secondary coronary arteries from the opposite aorta supplying the infected heart with oxygen means it is much lower than it would be in a human with the same heart condition. But I'm wondering what the actual chance of getting a heart attack with symmetric ventricular hypertrophy, chest pain, and cardiomegaly is. I imagine it would be low but how low? Low enough not to worry about MI at her young age? I tried cardiology forums and they said "this heart attack thread isn't relevant, locking" so my steering clear of medical forums was right. They won't help at all with this heart attack scenario. Alma is 17 just to give you an idea of how young she is. Anyway, not only am I wondering what the chance of a heart attack in this scenario is but I am also wondering how to approach this heart attack if it happens. I was thinking maybe this: This is just an example of what I might do at this point. Do you have any suggestions about what I should do if my story gets into this adolescent heart attack scenario?
