In August 2011, one of Dr Leslie Lam's patients filed a complaint accusing him of professional misconduct. Six years later, the prominent cardiologist was cleared of all charges following an appeal to the High Court.

Dr Lam told The Straits Times yesterday that the issue weighed heavily on his mind during those six years. "It certainly gave me a lot of sleepless nights," said the 75-year-old. "My reputation was so badly damaged."
