Prehypertension during young adulthood and coronary calcium later in life
View abstract on PubMed
Summary
This summary is machine-generated.Prehypertension in young adults is common and linked to coronary atherosclerosis 20 years later. Maintaining systolic blood pressure below 120 mm Hg before age 35 offers significant long-term health benefits.
Area Of Science
- Cardiology
- Preventive Medicine
- Public Health
Background
- High blood pressure in middle age is a known cardiovascular disease risk factor.
- The impact of mild blood pressure elevations in young adulthood remains unclear.
- Early identification and management of hypertension risk are crucial for long-term cardiovascular health.
Purpose Of The Study
- To assess the association between prehypertension exposure before age 35 and coronary calcium presence later in life.
- To quantify the cumulative effect of prehypertension on early signs of coronary atherosclerosis.
- To inform preventive strategies for cardiovascular disease starting in young adulthood.
Main Methods
- A prospective cohort study involving 3560 Black and white men and women aged 18-30 years.
- Blood pressure trajectories were tracked over 20 years, calculating cumulative prehypertension exposure (mm Hg-years).
- Coronary calcium was measured at a mean age of 44 years to assess subclinical atherosclerosis.
Main Results
- 18% of participants developed prehypertension before age 35, often associated with being Black, male, overweight, or of lower socioeconomic status.
- Cumulative prehypertension exposure showed a graded association with coronary calcium, particularly systolic prehypertension (P < 0.001).
- The association persisted even after adjusting for later blood pressure and other cardiovascular risk factors.
Conclusions
- Prehypertension in young adulthood is prevalent and predicts coronary atherosclerosis 20 years later.
- Maintaining systolic blood pressure below 120 mm Hg before age 35 is associated with significant long-term cardiovascular benefits.
- Early intervention for prehypertension may reduce the future burden of coronary heart disease.
