White House Press Secretary Sarah Sanders said that Kudlow was discharged from Walter Reed National Military Medical Center and that his recovery was going well.
Donald Trump's top economic adviser, Larry Kudlow, is expected to recover fully after suffering a mild heart attack in the USA shortly before the president's nuclear summit with North Korean leader Kim Jong Un, a White House aide said Tuesday.
He's expected to make a full recovery.
She said the president was looking forward to "seeing him back to work soon".
Kudlow's heart attack came less than three months after Trump tapped the former CNBC host and commentator to chair the White House's National Economic Council.
The President had broken the news of the heart attack via his Twitter account just moments before his historic summit with North Korean leader Kim Jong Un. "He should pull back on his statements".
Kudlow replaced Gary Cohn, who resigned in March.
Kudlow, who was White House budget director under President Ronald Reagan, is a fervent defender of so-called supply-side economics - the theory that growth is best stimulated by lowering taxes and reducing regulation - an approach embraced by Trump. He left that position in the early 1990s to treat an addiction to alcohol and drugs. He had always been known as a respected business and economics commentator, getting his own CNBC show in 2011.
The White House has described the cardiac event as "very mild".
