Insights
This study found a high prevalence of traditional cardiac risk factors (TCRFs) in Iranian patients undergoing coronary artery bypass graft (CABG) surgery. Over 90% of patients had at least one risk factor, highlighting a significant public health concern.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Traditional cardiac risk factors (TCRFs) significantly impact outcomes after coronary artery bypass graft (CABG) surgery.
- Understanding the prevalence of TCRFs in specific populations is crucial for targeted interventions.
Purpose of the Study:
- To determine the prevalence of hypertension, diabetes mellitus, hyperlipidaemia, smoking, and family history of premature coronary artery disease (CAD) in Iranian patients undergoing CABG.
Main Methods:
- Retrospective analysis of prospectively collected data from a registry.
- Inclusion of 10,622 consecutive patients undergoing elective CABG between March 2001 and September 2005.
- Data collection on traditional cardiac risk factors.
Main Results:
- The majority of patients were overweight (BMI ≥ 25.0 kg/m²).
- High prevalence rates were observed for hyperlipidaemia (63.9%), hypertension (over 50%), diabetes mellitus (over 33%), and smoking (37.7%).
- 91.6% of patients had at least one TCRF; women exhibited higher rates of obesity, hyperlipidaemia, hypertension, diabetes, and family history of CAD compared to men, while smoking was more prevalent in men.
Conclusions:
- A high prevalence of most traditional cardiac risk factors was identified in the Iranian population undergoing CABG.
- These findings underscore the need for robust cardiovascular risk management strategies in this demographic.
Objective:
It is well known that the traditional cardiac risk factors (TCRFs) affect short-term and long-term outcome following coronary artery bypass graft surgery (CABG). The objective of this study was to detect the prevalence of these risk factors i.e., hypertension, diabetes mellitus, hyperlipidaemia, smoking and family history of premature CAD in an Iranian population undergoing coronary artery bypass surgery.
Methods And Results:
From March 2001 to September 2005, we retrospectively analysed prospectively collected data from our registry. Data were achieved regarding TCRFs in 10,622 consecutive patients undergoing elective CABG. Mean age of the patients was 58.75 +/- 9.72 years and 74.4% were men. The majority of the patients were overweight with a body mass index (BMI) > or = 25.0 kg/m2. Hyperlipidaemia was present in 63.9% of the patients. Over half of all the patients had hypertension and over one third diabetes. History of smoking was present in 37.7% of the patients and one third had a family history of CAD. Of all the patients, 91.6% had at least one of the TCRFs. As compared to men, women were more overweight or obese, and had a greater prevalence of hyperlipidaemia, hypertension, diabetes mellitus, and family history of CAD but smoking was much more common in men than in women.
Conclusion:
The current study revealed a high prevalence of most of TCRFs in an Iranian population that underwent CABG.
