The prevalence of coronary heart disease is over twice as high in men (4.7%) than in women (2.0%). For all risk factors analysed the prevalence is greater in men than in women – most notably smoking being 1.6 times higher in men (of those with a status recorded) and diabetes 1.4 times higher. However, high blood pressure is only recorded as being 6% higher in men than in women. Given the knowledge that high blood pressure is a key driver of cardiovascular disease, this could represent under recording, and therefore undertreatment, in men.
