Corrie's Robert Preston is set to suffer from a heart attack as his steroid addiction continues to spiral out of control.

Viewers have seen Robert struggle with his secret drug use, but the news will be out when finacée Michelle Connor is told the shocking truth.

Scenes that will air next week will show Carla Connor spilling the beans to Michelle of Robert's big secret.

Carla speaks to young doctor Ali about steroid abuse and it doesn’t take him long to clock on that she’s talking about Robert, actor Tristan Gemmill.

When Michelle discovers that Carla and Ali are sleeping together, Carla lashes back and tells her all.

The furious finacée confronts her husband-to-be and demands to know if it’s true and he lies to her by telling her that he’s off them.

After his dark secret is exposed, he promises that he will stop taking the performance enhancing drugs that he became hooked on during training for the boxing match.

Unfortunately, he doesn't keep his word and viewers will see hi taking a heart attack next month which lands him in hospital.

The Star reported that Tristan Gemmill who plays the character or Robert, praised TV bosses for the storyline and said: "It feels topical to be covering an issue like this, especially when we see everything that's going on in the wider world about what male behaviour has been in the past.

"We're trying to hold a mirror up to what's going on and I think the producers have timed it pretty well."

The heartbreaking scenes will air on Coronation Street over the coming weeks and we cannot wait.
