The new findings suggest that individuals with higher systolic blood pressures have a greater risk of intracerebral haemorrhage (stroke caused by bleeding within the brain tissue), subarachnoid haemorrhage (the deadliest form of stroke), and stable angina, whereas raised diastolic blood pressure is a better indicator of abdominal aortic aneurysm risk.
“Our findings do not support the widely held assumptions that systolic and diastolic pressure have similar strong associations with the occurrence of all cardiovascular diseases across a wide age range,” explains lead investigator Dr Eleni Rapsomaniki from The Farr Institute for Health Informatics Research, London, UK.
