Of course evil people have heart problems.

Even if they got all the nutrients
and supplements in the world,
all the tech to boost their health.

You see
HEART is based on love energy, life energy.

When you go against principles of love and life,
you start dying, regardless you fit your body is, regardless of age.

slowly suiciding yourself. You get stony heart, then a black heart.

Power and wickedness are illusion, delusional feelings, not reality. No life force supports evil, actually.
That's why it is such a swampy attitude to maintain. Difficult to get out of, because you subcons. know you fight against the universe, still doing it, become bitter, build walls around yourself, pretend security and confidence in perversion of abusing and betraying fellow humans.

Being evil, doing evil is the biggest fantasy you can play, but the end game is always self destruction. possibly even true death, oblivion of the soul, being lost forever.

Humans are evolutionary, ascending "immortal" creatures in spirit, but the eternity is still an achievement, not automatic. It can be lost. The longer you insist denying the reality of the universe and the life force itself. Love and brotherhood. Sonship of God.
