Actually in the old days Cardiac Hill was the description for the hill road from Summer Dreams / juice bar - - up to the top of the headland and Akrotiri Bar.
Parts of this hill really are steep but manageable, (first 150 metres), just do it a bit at a time, once past Tsaros Poolbar, the road is not quite as steep and a slow pleasant walk.
Somehow over the years, the term Cardiac Hill seemed to transfer to the main road to Romanza, and as the others state - is not as bad as it looks or sounds.
If the going gets tough - stop for a restful drink or coffee half way - going back down is easy!
