Italy's premier Paolo Gentiloni is recovering in a Rome hospital from an emergency surgical procedure to clear a blocked coronary artery, his spokesman said on Wednesday.
The 62-year-old premier is conscious and in good condition, Gentiloni's spokeswoman, Flaminia Lais said.
Gentiloni underwent angioplasty surgery at Rome's Policlinico Gemelli hospital after felt unwell on his return to Rome Tuesday from a meeting with French president Francois Hollande in Paris.
He expected to stay in hospital for three or four days and had been due to meet British prime minister Theresa May in London on Thursday.
Gentiloni was appointed premier in December when Matteo Renzi resigned following a crushing defeat in a referendum on proposed changes to Italy's constitution aimed at streamlining lawmaking.
Gentiloni's heart procedure comes amid a customary round of official visits by an Italian head of government after taking office.
Gentiloni was foreign minister in Renzi's centre-left government.
