Former F1 star Carlos Reutemann remains in intensive care in Rosario's Sanatorio Parque clinic but in stable condition following a procedure undertaken on Tuesday to treat a digestive hemorrhage.
Reutemann, a twelve-time Grand Prix winner, was transferred from a hospital in Santa Fe to Rosario after suffering from internal bleeding.
After an endoscopic procedure on Tuesday, the 79-year-old former Governor of Santa Fe and Argentinian Senator remained in stable condition in the Sanatorio Parque's IC unit.
"Hospitalised in ICU, lucid, in communication with the environment, with no other organ failure," the medical institution said in a statement.
"No signs of digestive bleeding since the endoscopic haemostasis procedure performed yesterday."
Reutemann's distinguished career in F1 saw the popular Argentinian take part in 146 Grands Prix from 1972 to 1982, winning races with Brabham, Ferrari and Williams and scoring a total of 46 podiums.
In 1981, Reutemann head into the final round of the F1 world championship at Las Vegas with a one-point lead over Brabham's Nelson Piquet.
But the chips fell the wrong way for the Williams driver around the Caesar's Palace parking lot makeshift street circuit where Reutemann failed to score, handing the laurels to Piquet and allowing the Brazilian to secure the first of his three world crowns in F1.
After retiring from motorsport, Reutemann embarked on a political career in his home country, becoming the governor of his native province of Santa Fe, and later a federal senator.
As a popular politician, Reutemann was considered by many to be a worthy candidate for President of Argentina, and although he considered running in his country's 2011 general election, he ultimately declined to do so.
