Is it possible to clear out cholesterol/plaque from arteries?

I went to my doctor yesterday. Recently, I have been experiencing chest pain. They did an EKG which came back normal. They checked my cholesterol and it was high (241). I was just wondering if I get it down to an acceptable level, will the pain go away for good. And, if I eat a diet high in fruits and vegetables will it COMPLETELY clear my arteries of all plaque for good? And how long does it take if I am eating fruits and vegetables regularly to get a good cholesterol reading?
