[Cleveland Clinic]

I am not sure how the atherosclerotic and HTN fit into all this.  It seems to me that he developed some form of sepsis (infection), likely related to a bacteria, potentially staphylococcus or streptococcus, which then led to severely low blood pressure.  This can be fatal by causing failure of all major organs.  Sorry about your loss.
