Aim:

In this study, we have tried to elucidate the influence of major cardiovascular risk factors such as age and gender on the prevalence of occlusive coronary artery disease (CAD) and define the prevalence of patients presenting with acute myocardial infarction(MI) or post-procedural MI in patients undergoing coronary angiography(CAG) at our center.

Material and Methods:

Five hundred consecutive CAG procedures carried out between may 2015 and july 2015 were retrospectively analysed in terms of demographic data (age, gender, prior sten tor coronary bypass procedure), angiographic characteristics (extense of CAD,number of occluded vessels, treatment and stent number),occurence of MI before or after the procedure.

Results:

In our study population (mean age 62.06±11.18 and 63% male) the rate of normal coronary arteries (NCA) was 14,6%, of nonocclusive CAD was 21,8%, of slow flow phenomenon was 3,8% and occlusive CAD was 59,8%. The mean age of patients with NCA was 56,1±10,5 years which was significantly lower than that of the patients with occlusive CAD (mean age 64±11,3) and nonocclusive CAD (mean age61±10) (p=0,000 and p=0,006 respectively). The patients with occlusive CAD were significantly older when patients with CAD were analysed.(p=0,026). Patients with NCA were more likely to be female (%74) while male gender was more common in patients with occlusive (71,2%) and nonocclusive(64,8%) CAD. Age did not effect the prevalence of presentation with MI. (p=0,11). There was no statisticaly significant difference in presentation with MI in terms of gender (p=0,287) but older women more commonly presented with MI when compared to men(p=0,015) and men experienced more thromboembolic complications after procedure when compared to women (p=0,011).

Conclusion:

The analysis of the KAG results showed that the prevalence of occlusive CAD is high among our patients. In the light of these data, more emphasis should be given to the primary prevention of cardiovascular diseases in our region.
