Guidelines:Aim to present all the relevant evidence on a

particular issue in order to help physicians to weigh the benefits and risks of a particular diagnostic or

therapeutic procedure.They should be helpful in everyday clinical decision-

making.

The Rationale for an active approach to the prevention of cardiovascular diseases (CVD) is firmly based on five observations:

CVD is the major cause of premature death in most populations; it is an important source of disability and contributes in large part to the escalating

costs of health carethe underlying pathology is usually atherosclerosis, which develops

insidiously over many years and is usually advanced by the time symptoms occur

death, myocardial infarction and stroke nevertheless frequently occur suddenly and before medical care is available, and many therapeutic

interventions are therefore inapplicable or palliative the mass occurrence of CVD relates strongly to lifestyles and modifiable

physiological factors risk factor modifications have been unequivocally shown to reduce mortality and morbidity, especially in people with either unrecognized or recognized

CVD.

Objectives of Cardiovascular PreventionObjectives of Cardiovascular Prevention

To reduce the incidence of first or recurrent clinical events due to coronary heart disease, ischemic

stroke and peripheral artery disease.The focus is prevention of disability and early

death.Lifestyle changes, management of major CV

factors, use of different prophylactic drug therapies.Intermediate end-points… subclinical organ

damage [LVH, CA plaque, ED, electrical instability]

Recommendations for assessment with fasting lipid profile (total cholesterol, high density lipoprotein cholesterol, triglyceride and low

density lipoprotein levels) in various patient groups

Patient group Frequency

Patients with coronary artery disease, CAD or peripheral vascular disease

Annually

Patients with xanthomata or a family history of early CAD with genetic dyslipidemia

One measurement during youth, repeated at age 30 years; if no evidence of genetic dyslipidemia, resume testing every five years from age 40 (for men) or 50 (for women)

Adults with diabetes Repeat every one to three years or as clinically indicated

Men aged 40 to 70 years, women aged 50 to 70 years

Every five years

Clinical judgement should be used for patients with multiple risk factors who are approaching these target ages. Note that the translation of number of risk factors into risk

levels is incorrect outside of these age ranges. CAD Coronary artery disease

BP …. Based on BP alone rather than BP in the context of absolute CV risk.

British recommendations:BP>160/110 mmHg should be lowered irrespective of

other factors because of established benefit in reducing the cerebrovascular component of CV risk

15% risk of CHD corresponds to 20% overall CV risk.

Introducing drug treatment for raised BP or lipid concentration should be strongly determined by the

absolute risk of developing disease.An absolute risk of coronary heart disease >15% (equivalent to a CV risk of 20%) over 10 years is

sufficiently high to justify drug treatment.

Exceptions to treatment based on absolute risk are:Exceptions to treatment based on absolute risk are:

Hypertension (SBP>160mmHg or diastolic BP>100mmHg) or HTN with associated target

organ damage.Familial hypercholestrolemia or other inherited

dyslipidemia.Diabetes Mellitus with associated target organ

damage.Drug treatment is required for all these patients to

reduce the risk of CHD (and CV risk).

reduce the risk of CHD (and CV risk).

A staged approach to managing patients at high risk is advised.

As a minimum, those with absolute CHD risk >30% should be targeted and treated now.

As resources allow individuals with a risk >15% should be progressively targeted

For all high risk patients every effort should be made to achieve the lifestyle, risk factor and

therapeutic targets.

Public health approaches, such as reducing calories, saturated fat and salt in processed food

Increasing community and school opportunities for physical activity can achieve a downward shift in the

distribution of population’s BP, reduce morbidity, mortality and the lifetime risk of an individual becoming

hypertensive.Food manufactures and restaurants should reduce sodium

in food supply by 50% during the next decade
