No, worms have 10 hearts, in 5 pairs.
They have two main blood vessels that extend through the length of their body: a ventral blood vessel which leads the blood to the posterior end, and a dorsal blood vessel which leads to the anterior end. The dorsal vessel is contractile and pumps blood forward, where it is pumped into the ventral vessel by a series of hearts, a typical lumbricid will have 5 pairs of hearts; a total of 10.

I'm not sure but if you rip them in half they can still live and I think regrow but they can definitely live so maybe they do.
