 Re: ...he is grave risk of a heart attack.
No. To me it sounds much better with the article, but here are some examples without :
The deadly combination of obesity, inactivity, excessive smoking, and an unwholesome diet put Mr. Honeyman at grave risk of heart attack every day.
Meanwhile, millions of Americans have been placed unnecessarily at grave risk of heart attack.
However, these were the only two I found as opposed to over two thousand for "grave risk of a heart attack". So here, I think my intuition was probably sound. |
