Wald, the lead study author, noted that "the initial cost of preventive [angioplasty] is higher, but there would be a reduced cost thereafter because of a reduced need for hospital admission, cardiac investigations and repeat procedures."
Wald reported he was a director of Polypill Ltd, a medication program for prevention of heart attack and stroke.
