How exactly does someone die from lack of health insurance?

I keep seeing this quote. I could see dying from lack of oxygen. Or food. Lack of food would kill you eventually. Or lack of a seat belt. Please explain.

They are denied access to health care to prevent emergencies. Unless they want to go bankrupt that is. Why does no other developed nation have the US model of healthcare? Because in the US model, insurance companies use death panels to deny care to those they are meant to cover. And then they raise costs [1]. Not only does the USA spend more on healthcare than any other nation [2], it finds itself bottom of the table when it comes to preventable deaths due to treatable conditions when it comes to developed nations [3]. The sad thing is that rather than focus on these things, the right spreads lies and half truths about the reforms and how healthcare works abroad [4]. Even sadder is the fact that the reforms are so simple [5]. But, if you think that my points are wrong, e-mail me with proof.
