Sinha, 67, was admitted to Kokilaben Hospital in July last year after he complained of breathlessness due to some paint work at his residence. He underwent bypass surgery as blockages were discovered in his coronary arteries.
"After a strenuous election campaign and resounding victory in Lok Sabha elections, Sinha was admitted to Kokilaben Hospital for his regular periodic check up. All tests are normal and he should be discharged later today," said Dr Ram Narain, Executive Director, Kokilaben Hospital.
Earlier, Shatrughan's son Luv told PTI that his father was doing fine and is in hospital for the routine check up because of the bypass surgery he had undergone.
The actor, who made his Bollywood debut in 1969 with 'Sajan', is currently BJP MP from Patna Sahib in Bihar.
