Major risk factors for coronary heart disease in hypertension: implications for management
1Hypertension Clinic, St. Mary's Hospital, London, UK.
Insights
Managing hypertension effectively requires addressing coronary heart disease (CHD) risk factors. Public health initiatives targeting modifiable factors like high blood pressure (BP) and cholesterol can reduce CHD morbidity and mortality.
Area of Science:
- Cardiovascular Medicine
- Public Health
- Epidemiology
Background:
- Hypertension is a primary cause of death due to coronary heart disease (CHD).
- Established CHD risk factors in the USA are likely applicable to the UK.
- Effective management of hypertension is crucial for preventing CHD.
Purpose of the Study:
- To emphasize the importance of CHD prevention in hypertension management.
- To highlight modifiable risk factors contributing to CHD.
- To advocate for public health measures in the UK for CHD reduction.
Main Methods:
- Analysis of large population studies on hypertension and CHD.
- Identification of modifiable and non-modifiable risk factors for CHD.
- Review of prospective data on public health interventions for risk factor modification.
Main Results:
- Hypertension is causally linked to CHD.
- Modifiable risk factors include elevated LDL-cholesterol, smoking, high BP, diabetes, inactivity, low HDL-cholesterol, and oral contraceptive use.
- Public health measures can favorably impact multiple modifiable risk factors.
Conclusions:
- A comprehensive approach to hypertension management must include addressing other CHD risk factors, especially lipid profiles.
- Public health interventions in the UK could significantly reduce CHD morbidity and mortality.
- Ignoring other CHD risk factors will limit the impact on the primary objective of reducing CHD.
Abstract:
Since most deaths attributable to hypertension are the result of coronary heart disease (CHD), the major objective in the management of hypertension should be the prevention of CHD. Data from large population studies, mainly carried out in the USA, leave little doubt that hypertension is causally associated with CHD and we have no reason to believe that the risk factors for CHD in the United Kingdom are any different from those established in the American studies. In addition to the non-modifiable factors of age, sex, and family history, there are modifiable risk factors which include raised serum low density lipoprotein (LDL)-cholesterol, smoking, raised BP, diabetes mellitus, lack of exercise, low high density lipoprotein (HDL)-cholesterol, and use of oral contraceptives. Medicine clearly has a large and critical task in dealing with the current epidemic of CHD-associated illness. However, it is also apparent from prospective data from several countries that a preventative approach by means of public health measures is likely to have a favourable impact upon several of the modifiable risk factors. It is likely that if resources were made available for this purpose in the United Kingdom, a major reduction in morbidity and mortality from CHD would ensue. If we continue to manage hypertension without paying attention to other CHD risk factors, particularly abnormal lipid profiles, then we are unlikely to make an impact on morbidity and mortality from CHD which is our primary objective.
