Surveillance of Cardio Vascular Risk Factors Among 
Patients Undergoing Coronary Artery Bypass Surgery
Shumaila Furnaz* and Hasanat Sharif

Surgery, Aga khan university and hospital, Karachi, Pakistan

Objective
To investigate the prevalence of cardiovascular risk factors among 

patients undergoing elective Coronary Artery Bypass Graft surgery 
(CABG) in Karachi, Pakistan.

Introduction
According to world health organization report 2011, coronary 

artery diseases are the number one cause of death globally: more 
people die annually from coronary artery diseases than from any other 
cause.

An estimated 17.3 million people died from coronary artery 
diseases in 2008, representing 30% of all global deaths. Of these 
deaths, an estimated 7.3 million were due to coronary heart disease 
and 6.2 million were due to stroke. Low- and middle-income countries 
are disproportionally affected: over 80% of coronary artery diseases 
deaths take place in low- and middle-income countries and occur 
almost equally in men and women.

Populations living in low and middle income countries are exposed 
to more risk factors associated with coronary artery disease as well as 
other non-communicable diseases and are less exposed to prevention 
efforts than people in high income countries.

Methods
Cardiothoracic surgery quality improvement is a core value of 

healthcare provision. In order to improve quality of care, information 
on key indicators needs to be systematically collected and maintained.

In 2006, the cardiothoracic department at Aga Khan University 
developed an infrastructure that would enable us to answer the more 
challenging research queries in cardiac surgery practice.

The resulting electronic cardiothoracic database is based on the 
European Association of Cardiothoracic Surgeons database and the 
Society of Thoracic Surgeons database.

We chose the following aspects of patient care to be included in 
the database form: pre-surgery patient condition and medications, 
anesthesia information, perfusion information, surgery information, 
recovery information, status of the patient atdischarge,30-days and 
365-days post-surgery follow-up information .

Information was collected through structured questionnaire by 
trained data abstractor and entered into Microsoft Access software 
and analyzed in SPSS(Statistical package of social sciences) software.

Results
In this prospective study 2073 undergoing elective CABG were 

included. Mean age of the patients was 54.85 9.7 years, 14.7% of 
patients were females. Prevalence of risk factors among the study 
population, included: 47.10% were overweight, 14.7% were obese, 
47.7% were diabetic, 69.50% were hypertensive, 50.20% were 
dyslipidemia, 47.7% were as smokers, 9.2% were in renal failure, 
addition, 53% of patients had family history of coronary artery disease, 
46.7% had a history of myocardial Infarction (MI). The,operative 
mortality rate was 0.3%.,Post surgery complications included renal 
failure in 14.8% of patients, arrhythmias in 7%, reoperation in 2.3%, 
prolonged ventilation in 3.1%.

Conclusions
There is a high prevalence of risk factors like dyslipidemia, 

hypertension, diabetes and smoking for ischemic heart disease in our 
population. Once we establish this fact we will work to control the 
risk factors and reduce the burden of disease so that’s why this study 
is being done
