The ministry said that the patient had multiple co-morbidities, including diabetes, hypertension and high cholesterol.

He was admitted to Singapore's Changi General Hospital on July 16 after four days of flu-like symptoms and was diagnosed with influenza A/H1N1.

"He died of a heart attack, contributed by severe pneumonia with underlying influenza A/H1N1 infection," the ministry said in a statement.
