Citando:
"Dr Sasaki concluded: “Our results support the hypothesis that sleep deterioration may lead to cardiovascular disease. Poor sleep in patients with ischaemic heart disease may be characterised by shorter sleep and brief moments of waking up.”

He added: “Difficulty maintaining sleep reflects an increase in sleep fragmentation, which refers to brief moments of waking up and causes overactivity of the sympathetic nervous system and adrenocortical axis.”

Previous research, published by the University of California San Francisco last year, suggests people who do not sleep all the way through the night are at a 29 per cent increased risk of developing an irregular heartbeat."
