Lead researcher Dr Philip Greenland said: "We have [known / knowing] for many years that there is a small [number / numbers] of modifiable risk factors for heart disease, and at least one, but often [more / most] than one, are present in the background leading [down / up] to heart attacks, heart failure, or strokes." He [add / added] : "Efforts need to be made to [threat / treat] that factor to prevent heart attack, stroke, [as / or] heart failure." Dr Greenland said: "The goal now is to work harder [on / of] finding ways to control these modifiable risk factors."
