Historically, there is an evidence as to the antiquity of coronary heart
disease (CHD). The heart of a mummy of 50 years old lady by the name of
Teye, found its way from Egypt after 3000 years, to the Department of
Pathology in the University of Buffalo, NY. Report on this delayed autopsy
included the following: "The coronary arteries showed well marked fibrous
thickening, chiefly of the intima, with good sized patches of ca1cificatien ...,
there were areas of fibrous tissue in the cardiac muscle like scars. It is probable
that the woman suffered from cardiac pain that would be called angina pectoris
today" (Long, 1931).
Coronary heart disease in the second half of the twentieth century, has
become epidemic in most industrialized countries (WHO, 1990). Moreover, it
is now emerging at an alarming rate in developing countries where rapid life
style changes have occurred over recent decades (Zimmet et aI., 1991).
The term Coronary Heart Disease (CHD) is synonymous with ischemic
heart disease. It is defined by the World Health Organization (WHO) as the
cardiac disability, acute or chronic, arising from reduction or arrest of blood
supply to the myocardium in association with disease processes in the coronary
arterial system. As neither the blood supply to the myocardium, nor the
coronary arteries, can be inspected in life without sophisticated investigations.
So, the disease can usually be recognized through its common syndrome (Miller
and Farmer, 1982).
The development of coronary heart disease is a silent process that
generally lasts decades before the onset of symptoms. Of the half million heart
attack deaths that occur annually in the USA approximately 60% occur
suddenly or outside of a hospital before treatment can be administered (Surgeon
General, 1988).
Coronary heart disease usually implies atheroma. This consists of fatty
deposits in the arterial wall which increase slowly in size, narrowing the
arterial wall. They may cakify or ulcerate providing a raw surface for thrombi
to form, which in turn embolize or occlude the lumen. Critical narrowing of
the lumen by atheroma, thrombus and/or spasm, cause regional myocardial
ischemia and infarction which predispose to fatal cardiac arrhythmias.

The clinical syndromes of coronary heart disease are as follows:
1. Angina pectoris.
2. Cardiac infarction.
3. Sudden death.
Despite its importance coronary heart disease is not a notifiable disease
and morbidity data are not routinely collected. Mortality rates are generally
used to compare incidence of coronary heart disease where no specially
mounted epidemiological study exists (Miller and Farmer, 1982).

Trends in coronary heart disease mortality are. of major public health
importance, both because of their impact on the overall health status of
populations and because of the insights these trends can provide for the control
of noncommunicable diseases in general (Beaglehole, 1990). |
