I would have. But one near death experience will make a person more agressive.
In my case, since I had other symptoms, I was worried and ended up wearing the 24 hour heart monitor, having an echocardiagram, etc.
I will say, though, that initially my doctors did not believe something so serious could possibly be wrong with such a young woman's heart (I was 32), so I really had to advocate for myself and my condition deteriorated as they tried to figure out what was going on. Also, if Lina's husband was in any way overbearing or controlling, she may have had a tendency to minimize her symptoms to herself and not make a fuss - in this way he may very well have had some responsibility, as did she. Some women do tend to minimize their own medical conditions, as well as having them minimized by the medical community and their own spouses. My father drove my mother around for an hour during her heart attack, thinking it might "get better" before finally going to the hospital.
