In the linked cohort study (doi:10.1136/bmj.d643), Sundström and colleagues followed more than 1.2 million young Swedish army conscripts over a 37 year period to assess the relation between blood pressure in late adolescence and subsequent cardiovascular mortality and total mortality⇓.1
Blood pressure values track from childhood, indicating a slow process of disease evolution—a process that is now accelerated by the rise in childhood obesity. The clinical dilemma is when to intervene with lifestyle interventions and treatment.2 The problem with guidelines is that they are based on evidence from clinical trials with hard clinical end points such as coronary heart disease, stroke events, or death. Such events occur mainly in older people, so younger people with high blood pressure are largely excluded from the trials.
Furthermore, using cardiovascular risk assessment to stratify younger people for treatment is problematic because young people are at low short term risk and are thus unlikely to reach the required risk threshold for treatment. The decision about what to do with younger people with high blood pressure has also been compounded by a lack of data about the relation between blood pressure in the young and the subsequent risk of death.
The challenge to acquire such …
