Abstract Background: Atherosclerotic coronary artery disease is a major cause of death all over the world.
Among patients with coronary artery disease, there are different cardiovascular risk factors which may exhibit their
effects on coronary angiographic findings. This work aimed to study the relation of different cardiovascular risk
factors with coronary angiographic findings in patients with ischemic heart disease (IHD). Methods: This case-
series prospective study involved 220 patients with IHD who underwent coronary angiography in Mosul Cardiac
Catheterization Unit in Ibn-Sina Teaching Hospital over a period of five months from April 1
st
through August 31
st
2006. Patients with different coronary risk factors including smoking, positive family history of IHD, type 2 diabetes
mellitus (T2DM), hypertension (HT), dyslipidemia, obesity and physical inactivity who presented with IHD were
categorized and compared according to presentations into; ST-elevation myocardial infarction (STEMI) ( n = 72),
Non-ST-elevation myocardial infarction (NSTEMI) and/or unstable angina (n = 98) and chronic stable angina (n =
50) and then the patients were re-grouped according to the number of cardiovascular risk factors into patients with <
3 risk factors (n = 125) vs. those with > 3 risk factors (n = 95). Results: There were significant associations between
the risk factors and the angiographic characteristics in patients with IHD. There were more significantly stenosed
lesions among patients with > 3 risk factors compared to patients with < 3 risk factors (p < 0.05). Lesions were more
diffused (p < 0.01), with higher incidence of left ventricular dysfunction (p < 0.001) among former patients
compared to later ones. Conclusions: Significant findings were observed in the angiographic profile of patients with
multiple risk factors. There were more multi-vessels and diffused angiographic findings among patients with chronic
stable angina.

1. Introduction
Coronary artery disease (CAD) due to atherosclerosis is
a major cause of death all over the world and is the most
common form of heart diseases. Its incidence is increasing
among different populations and by 2020 it is estimated
that it will be the major cause of death all over the world
[1].
There is a number of personal attributes that may
increase liability for development of CAD often described
as risk factors. Nowadays, the prevalence of these risk
factors tends to increase in developing countries compared
to the developed world because of lack of institutional
implementation of specific policies that target these risk
factors [2].
In clinical practice coronary stenosis is often considered
as the main cause of myocardial ischemia. However, other
causes should be considered especially in normal coronary
angoigraphy in documented cases of ischemic heart
disease (IHD).
Although there are many advances in modalities for
evaluation of coronary lesions, however the coronary
angiography remains the “gold standard” for identifying
the presence or absence of stenosis in coronary arteries
and meanwhile provides reliable information during
percutaneous coronary intervention [3].
The main aim of the current study is to clarify the
impact of the cardiovascular risk factors on coronary
angiographic profile of the Iraqi patients with IHD. Other
specific objectives would rather be to test whether
different coronary risk factors can influence the patterns of
coronary angiography among different subtypes of IHD
