Conclusions:

Central obesity and smoking are extremely

prevalent in Egypt, contributing to an increased burden of

premature ACS, which warrants tailored prevention strate-

gies. The recognised tendency worldwide to treat men more

aggressively was less pronounced than expected.

Ischaemic heart disease is the leading cause of years of life lost

worldwide.

1

Despite advances in treatment, between 1990 and

2016, the global number of deaths from cardiovascular diseases

(CVD) for people aged more than 70 years increased by 54%.

1

While the CVD mortality rate has receded in high-income

countries between 2000 and 2012, low- and middle-income

countries have witnessed an increase.

2

Attempts at lowering

incident CVD require population-based preventative guidelines

that address the specific risk factors for each age and gender

group. Prevention is even more vital in lower-income countries

considering the high treatment cost of CVD, plus infections

and malnutrition, using limited health resources. Egypt is a

classic example, with overpopulation and a low per capita health

expenditure.

3

A gender-specific pattern of risk factors has emerged

worldwide, with female patients presenting with acute coronary

syndrome (ACS) having higher rates of diabetes mellitus,

hypertension and obesity, compared to men.

4

Furthermore,

universally there is a tendency for women to receive less-

intensive pharmacological and invasive treatment following

ACS.

4

The Middle East and North African (MENA) region is

no exception, with the Gulf countries overall reporting less-

aggressive treatment strategies in females, accounting for higher

complication and mortality rates in women.

5

Egypt is the most populous of the 20 MENA countries,

harbouring about 20% of the total MENA population of about

409 million.

6

It is unknown whether Egypt follows a similar

pattern of ACS risk factors and treatment strategies to that

observed in the MENA region and worldwide.

The past decades in Egypt have seen a transition from

prevalent undernutrition to obesity.

7

Over two-thirds of adults

and one-third of children are overweight or obese, surpassing

the average for Europe.

8

Three traditional CVD risk factors,

namely obesity, diabetes and hypertension, were the leading risk

factors for early death and disability in Egypt, as measured by

attributable disability-adjusted life years.

9

One in six individuals

has diabetes.

8

These factors are expected to be a major contributor

to ACS risk in Egypt but have not previously been quantified in

ACS patients across Egypt.

The CardioRisk project is a nationwide, cross-sectional study

of existing risk factors and management strategies for ACS in

Egypt. The present study is the first report of data collected in

the CardioRisk project, from November 2015 to August 2017.

The primary objective was to describe the risk-factor profile

among Egyptian patients with ACS and the different treatment

strategies adopted in intensive care units dealing with ACS

patients across Egypt. A secondary aim was to explore gender

differences with regard to ACS risk factors and treatments, to

enable informed design of national treatment guidelines and

gender-specific prevention protocols.

Methods

CardioRisk is a multi-centre, observational, cross-sectional

study of risk factors and management of patients presenting

with ACS to coronary care units in Egypt. A total of 30 units

participated from 11 governorates spanning the Mediterranean

coast, Nile Delta region and southern Egypt. Participating

coronary care units in each area included hospitals of different

levels of complexity, in order to capture a network of centres

representative of Egyptian reality.

Data were collected on patients presenting with ACS during

their hospital stay, with a focus on CVD risk factors, diagnostic

and management strategies, as well as in-hospital complications

and in-hospital mortality. To minimise selection bias, patient

enrolment was done consecutively on all weekdays for some

centres, and on pre-determined days in others. Management

of patients followed the existing diagnostic and therapeutic

strategies currently followed in each centre. No recommendations

for management were put forth during the study, and drug

prescriptions and management strategies were completely left to

the participating cardiologists’ decision.

Detailed information was given to each patient prior to

enrolment in the study, and data were included only after

obtaining signed informed consent. The study was approved by

the ethics committee of the Egyptian Association of Vascular

Biology and Atherosclerosis (EAVA)

[http://cardio-risk.org/

].

This study is an analysis of data collected during phase I

(November 2015 to January 2016) and phase II (February 2016

to August 2017) of the CardioRisk project. A total of 1 681

patients were included.

A 12-lead ECG was performed in all patients by a cardiologist

participating in the study. Based on electrocardiogram (ECG)

findings,patientswereclassifiedashavingST-elevationmyocardial

infarction (STEMI), non-ST-elevation myocardial infarction

(NSTEMI), unstable angina or other electrocardiographic

abnormalities. Plasma concentrations of troponins and the MB

fraction of total creatinine phosphokinase (CPK) were measured

to detect evidence of myocardial cell death.

Acutemyocardial infarction (STEMIorNSTEMI)wasdefined

by at least two of the following features: (1) electrocardiographic

changes (patients with or without ST-segment elevations), (2)

compatible clinical symptoms, and (3) troponin I

and/or MB fraction of CPK

>

8.8 ng/ml. Patients were enrolled

in the study if they were 18 years or older and diagnosed with

STEMI, NSTEMI or unstable angina.

Data were collected using a web-based system case-report

form (available on

www.cardio-risk.org)

, with a pre-determined

username and password for each participating investigator. The

following information was captured for each enrolled patient:

socio-demographics, CVD risk factors, history of co-morbidities

and prior drug use, presenting symptoms, laboratory data, ECG

findings, diagnostic and therapeutic procedures, in-hospital

complications and in-hospital mortality.
