My father had a cardiac arrest a month ago with no priop history of any cardiac or cholestrol issues. he had 2 stent for that and now he's on medication for the same he is diabetic too for past 8+ years. He's been tensed due to some family issues for few years. After the angio he lost weight skin in hand feets loosed. He's having some appetite issues he doesn't eat much and remains quite all day doesn't talk much in home keeps thinking all time. He's advised for Nexito 5 I want to know if it's safe in his present condition with CAD medicine and diabetes? Thanks in advance
