Does Potassium Deficiency Cause Ruptured Aneurysm?

She had been very ill because of the potassium deficiency so could there be any link between the two? She was also swollen beyond belief with edema, sharp pain in her entire body (legs especially), impaired vision, diarria, trouble swollowing, mood swings, heart palpitations...
