“…The sexspecific influence on coronary artery size, in turn, provides a possible explanation for the sex differences in coronary outcomes. Our findings are in agreement with results obtained from previous studies on coronary arterial dimensions (Roberts & Roberts;MacAlpin et al;Kornowski et al, 1997).…”

“…Several methods, such as, angiography, autopsy studies, intravascular ultrasound, have been occupied by various investigators to study the potential relation between the coronary artery dimensions and sex differences in prognosis of the coronary artery disease (Dodge et al, 1992;Roberts & Roberts, 1980;MacAlpin et al, 1973). However, it remains unclear whether sex differences in arterial dimensions simply reflect the effects of differences in body size or whether they are true sex-specific traits.…”

“…Several studies have demonstrated that age, body weight gender, genetics, and ethnicity play a role in this difference. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] In this study, we preferred using a tabular format to compare our study with earlier studies that employed a similar working methodology ( Table 3). Our study results were comparable to those of the studies conducted in the Iraqi population.…”

IntroductionWith its increasing incidence, coronary artery disease is one of the most common causes of morbidity and mortality especially in the industrialized countries, accounting for more than one-third of total deaths. Cardiovascular diseases are the cause of almost half of the deaths in Turkey. Amongst the European Union countries, Turkey is the fourth in the mortality caused by cardiovascular diseases in men and the first in women. [1,2] Coronary artery diameters are one of the most important factors that affect the technique and outcome of coronary by-pass operations. [3] Coronary arteries arise from the aorta as two branches, the right coronary artery (RCA) and the left main coronary artery (LMCA). After a short distance, the LMCA divides into two, and gives the left anterior descending (LAD) and circumflex artery (Cx) branches. While LAD runs along the anterior interventricular sulcus down towards the apex, Cx artery runs along the atrioventricular groove, giving rise to the left marginal branch. The circumflex then continues around the heart, terminating on its posteroinferior aspect, to supply blood to both the left and right atrium. [4] Lumen diameter of normal human coronary arteries and several factors affecting their lumen diameters have previously been studied in different countries on different populations. [5][6][7][8][9][10] To the best of our knowledge, there is no study with international recognition regarding normal AbstractObjectives: Cardiovascular diseases are the cause of nearly half of deaths in Turkey. Coronary artery diameters affect the procedure and outcome of coronary by-pass operations. The aim of this study was to measure the coronary artery diameters of the individuals with normal coronary artery on angiographic images to assess to provide data for a normal Turkish population and compare the results with studies from other countries.Methods: Seventy-seven male and female individuals between 31-79 years old were used in the study. Diameters of the two coronary arteries and their branches were measured in four segments using the Image J program. Results:The mean diameters of major coronary arteries i.e. LMCA, LAD, Cx and RCA were measured as 4.43±0.76 mm, 3.48±0.53 mm, 3.11±0.67 mm and 3.45±0.50 mm, respectively. Conclusion:This study revealed that the coronary artery lumen diameters of the Turkish population were parallel with the study conducted in the Iraqi population especially. A statistically significant correlation between certain coronary artery diameters were demonstrated also found. The findings of this study will contribute to the diagnosis and the treatment methods for the patients.

“…Zeina et al (10) reported LMCA cross-sectional area as smaller in women compared with men. In a small group of patients made up of 19 men and seven women MacAlpin et al (12) found no significant difference in normal coronary artery cross-sectional areas between genders. In our study, we found LMCA and LAD cross-sectional areas to be significantly larger in men compared with women (P < 0.001), while no significant difference was detected between genders with regard to CX cross-sectional areas (P = 0.094).…”

“…We believe that this difference might be attributed to patient demographics. While some studies reporting differences between female and male coronary artery cross-sectional areas are available, studies reporting the opposite are also found in the literature (10,12,13). Zeina et al (10) reported LMCA cross-sectional area as smaller in women compared with men.…”

C oronary artery disease is the leading cause of death worldwide. Thus, coronary artery imaging is one of the most commonly used diagnostic methods. Recently, coronary computed tomography angiography (CCTA) has become another widely used method in coronary artery imaging since it is a noninvasive technique that is easy to perform (1, 2).One of the major advantages of CCTA is that it allows for the measurement of not only two-dimensional diameters but also cross-sectional areas of the vascular structures. Thus, it is possible to calculate the degree of narrowing caused by atherosclerotic plaques in case of obstruction. It is also possible to predict the symptoms that may arise in a patient in relation to the obstruction and determine the treatment that can be performed using CT angiography.Atherosclerotic plaques are commonly seen adjacent to vascular bifurcations (3, 4). Left main coronary artery (LMCA) length is variable, and it is shorter in comparison with other main coronary arteries. Therefore, atherosclerotic plaques can occupy the whole vessel in some cases. In such cases, it is difficult to determine the degree of narrowing caused by the plaque since it is not possible to understand the reference artery diameter. Similarly, normal dimensions of the arteries might not be understood in cases of plaque build-up that occupy the long segment starting from the left anterior descending artery (LAD) and circumflex artery (CX) origin. Recently developed multidetector computed tomography (MDCT) technology provides valuable information in terms of understanding three-dimensional anatomy of coronary bifurcation and measuring the angle and vessel cross-sectional area (5, 6). This information is considerably important for the diagnosis and treatment of bifurcation lesions. 454From the Department of Radiology (S.V.), Mevki Military Hospital, Ankara, Turkey; the Departments of Radiology (E.Ö.  drersinozturk@gmail.com, K.K., M.S.) and Cardiology (U.K., E.K.), GATA Haydarpaşa Training Hospital, İstanbul, Turkey. PURPOSEOur aim was to determine whether there is a correlation between cross-sectional areas of the left main coronary artery (LMCA), left anterior descending artery (LAD), and circumflex artery (CX) in normal cases using coronary CT angiography. METHODExaminations of 180 patients (119 men and 61 women) were selected among 2248 consecutive coronary CT angiography studies. Cross-sectional areas of LMCA, LAD, and CX were measured at the level of bifurcation. Correlation between age, height, and body mass index and coronary artery cross-sectional areas was investigated and possibility of formulating a correlation between the cross-sectional areas of LMCA, LAD, and CX was explored. RESULTSMean cross-sectional areas of LMCA, LAD, and CX were found as 17.4±3.9 mm 2 , 12.5±3.1 mm 2 , and 10.5±3.0 mm 2 , respectively. While cross-sectional areas of LMCA and LAD were significantly larger in men, no significant difference was found between the sectional areas of CX in men and women. A multiple regression analysis was cond...
