Abstract
The concept of risk factors has evolved only over the past 45 years or so, and new factors are periodically added to the list as our comprehension of the disease process grows. To understand who is at risk and what risk actually means to an individual, one first needs to understand how CAD develops.
A cardiovascular risk factor is a condition that is associated with an increased risk of developing CVD .The epidemiological studies selecting a group that is representative of the population to which the information will later be applied.
Major risk factors are those that research has shown significantly increase the risk CVD. Other factors are associated with increased risk of CVD, but their significance and prevalence have not yet been precisely determined. They are called contributing risk factors.
The aim of this study was to study the pattern of risk factors profile in a sample of Egyptian patients with acute coronary syndrome.
To achieve such target, our study was carried on a (200) subjects representing a sample of Egyptian population with different demographic characters including gender, age. The subjects were recruited from one center in Egypt.
In this present study, 151 male (75.5%) and 49 female (24.5%) included, with statistical significant difference regarding the sex (as p value was .001) this reflect that acute coronary syndrome is more prevalence in male than female.
The mean age of the group is 52 years old, this means that premature CAD is common in Egypt; there is no significant difference between the mean age among males and females.
In our study family history of CAD represent statistical significant difference as P value is .045 for patient with no family history
In this study, Smoking, hypertension and diabetes are considered as a strong risk factor for acute coronary syndrome
In this present study, dyslipidemia, high levels of TC, LDL-C, TG and low HDL-C are considered significant factor in ACS events.
Furthermore, females of the ACS had higher total cholesterol, LDL and TG, and low HDL compared to males, but the most significant difference is in high LDL-C level and in low HDL-C in females.
In this present study, BMI represent a risk factor for ACS events with higher BMI in female than males. Increased weight and increased waist circumference and increased waist/hip are associated with increased incidence of ACS but no difference between male and female
In this present study, were significant positive correlation between weight, waist circumference and hip circumference and increased risk of CAD. Our results showed more increased weight and central obesity (represented by waist circumference and waist hip ratio) is associated with increased ACS incidence.
