The Heart

In Sanskrit, the heart means 'hrdayam'.
It consists of two syllables, 'hrt' and 'ayam', (centre - this).
I wonder if the English term 'heart', originated in the Sanskrit 'hrt', (centre), since we do tend to say "the heart of the matter is.....", if we mean to convey the 'crux' or 'essence' of something?
Hmm.....
