In general, yes.  Some stars do in act completely blow themselves apart, but
they are very much in the minority.

Most novae & supernovae leave a white dwarf, neutron star or black hole
behind.  These would be composed of the "heart" of the star.

Only the type Ia's are likely to be entirely disrupted, flinging even the
core material into space.

For what it's worth, all the non-standard Big Bang models would require some
*major* modification of physics to produce the observed elemental
abundances.
