“…Our results were consistent with those of previous studies, which showed that the diameters of coronary arteries are highly variable [19-22], considering that genetic and environmental factors including age, sex, ethnicity, and race have all been correlated with the coronary artery diameter. Previous reports have also indicated a gender-related difference in coronary artery diameters [23], although the potential differences in coronary artery diameters between males and females remain controversial. In our study, we did not find significant differences in coronary artery diameters between males and females, which was not consistent with previous reports.…”

Background: The diameters of the coronary arteries have been suggested to be a potential predictor of coronary artery disease (CAD). However, whether the diameters of the coronary arteries are associated with the coronary lesion severity on angiography has not been determined. Methods: One hundred sixty-seven consecutive adult patients (109 men and 58 women) aged 31–84 years who underwent coronary angiography for suspected or known CAD were enrolled. The known catheter tip diameter was used as the calibration to measure the diameters of coronary arteries, and the severity of coronary lesions was evaluated with the vessel score and Gensini score. Results: In patients with a higher vessel score and Gensini score, the diameters of the left main (LM), left anterior descending (LAD), left circumflex (LCX), and right coronary arteries (RCA) were smaller (all p<0.05) than those in patients with lower scores. Multiple linear regression analysis indicated that the average coronary artery diameter was significantly associated with the Gensini score (β=-0.444, p<0.00001). Moreover, the diameters of the coronary arteries were potential predictors of CAD, with areas under the receiver operating characteristic curves of 0.268 for average diameter (95% confidence interval [CI]: 0.183–0.353, p<0.00001), 0.356 for the LM diameter (95% CI: 0.266–0.445, p=0.005), 0.214 for the LAD diameter (95% CI: 0.136–0.291, p<0.00001), 0.366 for the LCX diameter (95% CI: 0.271–0.461, p=0.009), and 0.346 for the RCA diameter (95% CI: 0.245–0.447, p=0.003). Conclusion: The diameters of coronary arteries are inversely associated with the severity of CAD.

“…9 Previous reports have also indicated a gender-related difference in coronary artery diameters. 10 To the best of our knowledge, our study seems to be the only study with a larger Nepalese population where both of adjusted and unadjusted proximal coronary diameters were compared. The clinical and therapeutic implications of a narrow or wide coronary artery is obvious.…”

This study aims to assess the normal coronary diameters of patient who underwent coronary angiogram in Patan Hospital. Angiographic and demographic data of a total of 307 patients (155 males, 152 females; mean age 62.09±11.06 years) who underwent elective coronary angiography in Patan Hospital due to suspicion of coronary artery disease between 2017 and 2020 and in whom coronary angiography documented normal coronary arteries without any intra-luminal irregularity were analyzed retrospectively. Proximal diameters of the main epicardial coronary arteries were measured quantitatively using automated software analysis (Allura, Philips). The mean diameter of unadjusted/adjusted left main coronary artery, proximal left anterior descending artery, proximal left circumflex artery, proximal right coronary artery were 4.87±0.85mm/2.8±0.54, 3.8±0.7/2.19±0.439, 3.4±0.7/1.98±0.44, 3.6±0.85/2.07±0.53 respectively. Our study findings contradict the traditional belief that females have narrower coronary arteries than males. Our study showed the females have statistically significant larger unadjusted Right Coronary Artery diameter and adjusted Left Main Coronary Artery diameter. We believe that our findings may contribute to the global data pool of normal coronary diameters and can be utilized in future studies as a database.

“…However, most studies have evaluated autopsy specimens, and various factors associated with the acquisition, preservation, fixation, and analysis of the epicardial coronary artery have resulted in unreliable measurements and conclusions. 21 QCA is not subject to these factors and thus provides a good representation of the size of the coronary arteries.…”

Alcohol consumption may not affect the diameter of the coronary arteries in men with chest pain

Objective The effect of alcohol consumption on the risk of coronary heart disease is controversial. Several studies have assessed the effects of alcohol on the formation of atherosclerotic plaques, but few studies have evaluated the chronic effects of alcohol consumption on the coronary artery diameter. We investigated whether alcohol consumption affects the coronary artery diameter. Methods This prospective study enrolled men who were undergoing coronary angiography at the First Affiliated Hospital of Chongqing Medical University from November 2016 to December 2017. The participants were categorized into three groups based on their drinking behavior: heavy drinking (>175 g/week in the last 2 years, n = 70), moderate drinking (>42 to ≤175 g/week in the last 2 years, n = 53), and nondrinking (lifetime alcohol consumption of <98 g, n = 79). The diameters of the left and right coronary arteries were compared among the three groups. Results No significant differences in the diameters of the left and right coronary arteries were observed among the three groups. Conclusions Alcohol consumption may not affect the diameter of the coronary arteries.
