Insights
Current hypertension classifications are inadequate for risk stratification. A new diagnostic scheme combining blood pressure levels with risk factors and target-organ damage offers superior guidance for therapeutic decisions.
Area of Science:
- Cardiology
- Epidemiology
- Public Health
Background:
- High blood pressure (hypertension) risks are amplified by target-organ damage and other cardiovascular risk factors.
- Lowering blood pressure reduces cardiovascular disease incidence, with greater benefits for those with complications.
Purpose of the Study:
- To address the inadequacy of current hypertension classification schemes based solely on blood pressure levels.
- To propose a novel diagnostic classification for hypertension that improves risk stratification and therapeutic decision-making.
Main Methods:
- Developing a new classification system integrating blood pressure, cardiovascular risk factors, and target-organ damage.
- Incorporating a specific category for elderly individuals with isolated systolic hypertension and low diastolic blood pressure.
Main Results:
- Current schemes based only on blood pressure levels offer insufficient risk stratification.
- The proposed classification provides more accurate risk assessment and better therapeutic guidance.
Conclusions:
- A comprehensive hypertension classification incorporating risk factors and target-organ damage is essential.
- The new scheme enhances risk stratification, particularly for the elderly, leading to improved therapeutic decisions.
Abstract:
Many epidemiologic studies have shown that the risks associated with high blood pressure are considerably greater in those with target-organ damage and other risk factors. Clinical trials also have shown that although lowering blood pressure decreases the incidence of premature cardiovascular diseases, those with target-organ damage and other cardiovascular risk factors benefit considerably more than those with comparable levels of blood pressure who are free of complications or additional risk factors. The classification schemes currently in use for hypertension, which are based only on the level of blood pressure, provide inadequate risk stratification, can be misleading, and may lead to making erroneous therapeutic decisions. We propose a new diagnostic classification for hypertension that combines the level of blood pressure with the presence of other risk factors for premature cardiovascular events and target-organ damage in order to provide a more accurate risk assessment and offer superior guidance for therapeutic decisions. This scheme includes a new category for the elderly with elevated systolic blood pressure, who we now know have excessive morbidity and mortality rates if their diastolic blood pressure is low. Our new classification scheme is simple to use and yet comprehensive, and we feel it provides better risk stratification and is a better guide to therapeutic decision-making than those now in use.
