Egyptian Guidelines: Prevention
of Atherosclerotic CV Disease (Executive Summary)
ABSTRACT
In Egypt and third world countries, there are
no guidelines for prevention of atherosclerotic cardiovascular
disease. Clinical guidelines developed in wealthy countries
are inappropriate for most of the world population.
Guidelines address both lifestyle modification
and drug therapy for established risk factors. Because of limited
resources, thresholds of pharmacologic interventions for treatment
of hypertension and hypercholesterolemia and target levels were
higher than in western guidelines.
Two complimentary prevention strategies are
needed. The first is directed to the whole population aiming
at decreasing the risk profile of the whole community. The second
is an individual approach targeting principally high risk individuals.
Individuals at increased risk of developing
future cardiovascular events should be the first target of the
prevention programs. High risk individuals include patients
with established atherosclerotic cardiovascular disease (e.g.
angina, MI, stroke), diabetic patients with additional risk
factors, elderly individuals with risk factors, very high level
of a single risk factor and multiple (> 3) risk factors.
Complete smoking cessation is mandatory through
both community and individual approaches.
Both public and food industry should be aware
of the hazards of unhealthy dietary style. A heart healthy diet
should be made popular. This diet is low in animal fat and refined
sugar and rich in fibers and unsaturated fat.
Increased consumption of fruits, vegetables, whole grain, legumes
and fish should be encouraged. Food labeling, government legislations
and media campaigns are important tools.
All individuals should be encouraged to establish
and maintain at least 30 minutes of moderate intensity physical
activity as 5 or more days/ week.
A normal body weight (BMI 20-25 Kg/m2) and
a waist circumference < 94 cm in men and < 80 cm in women
are recommended. Control of obesity requires indefinite dietary
and behavior therapy and regular physical activity.
Combination of pharmacotherapy and lifestyle modification is
more effective in weight loss than either approach alone.
Blood pressure goal < 140/90 mmHg is recommended
in all individuals, lower levels may be required in high risk
individuals. Accurate blood pressure measurements should be
encouraged in all routine office visits.
Start of drug therapy for high BP, unless there
is an emergency, should follow a period of monitoring and repeated
measurements over a period varying from days to months depending
upon BP level and global risk profile.
In patients with dyslipidemia an elevated serum
LDL-C should be confirmed on at least two separate measurements.
Initiation of statin therapy is recommended only after failure
of dietary intervention for a period of 3-6 months and should
take into consideration the level of LDL-C and the patient's
global risk profile. The use of stains for primary prevention
is not recommended unless LDL-C is > 210 mg/dl, or if LDL-C
>160 mg/dl in presence of multiple risk factors.
Diagnosis of diabetes depends on accurate and
repeated estimation of plasma glucose (PG). An optimal (normal)
fasting PG is less than 100 mg/dl. If diet and exercise fail
to normalize blood glucose within 3 months, oral therapy is
initiated.
Screening for hyperglycemia is indicated for individuals most
likely to have impaired glucose tolerance, those with established
atherosclerotic cardiovascular disease, hypertension and dyslipidemia.
