Everyone has a responsibility for their own safety. We should do what is reasonable to reduce harm and risk to others, but there is only so much that can be reasonable. If a person wears dark clothing, doesn’t use crosswalks, doesn’t check for cars etc at what point does their safety become their responsibility?
AFAIK angina comes from the Latin word angere which means to suffocate.
Angina pectoris being suffocating chest pain, often accompanied by shortness of breath.
And Ludwig angina litteraly suffocating a person via swelling.
