BACKGROUND Blood pressure (BP) in the right and left arms can be different. This inter arm difference (IAD) in BP can be systolic (IAD - SBP) and / or diastolic (IAD - DBP). IAD of ≥ 10 mm of Hg is considered significant. SYNTAX score is used to assess the complexity of coronary artery lesions. Prevalence of IAD in patients undergoing coronary angiography (CAG) and its relationship to complexity of coronary artery disease is unclear. METHODS In 100 patients taken up for CAG, BP was recorded in both the arms simultaneously with automated devices using oscillometric method. Significant IAD was defined as ≥ 10 mm of Hg. Using SYNTAX score, patients were divided into two groups; those with a lower score < 22 and those with a higher score ≥ 22. Data was analysed using SPSS version 16. Mean difference of the variables was analysed using Independent t test. Association of interarm BP difference and high SYNTAX score was analysed using Chi Square test. RESULTS Significant IAD of ≥ 10 mm of Hg was noted in 16 out of 100 patients. SYNTAX score of ≥ 22 was seen in 30 patients. IAD - SBP ≥ 10 was noted in 23.3 % in patients with higher SYNTAX score as against 2.9 % in those with lower score (p 0.001). IAD - DBP ≥ 10 was seen in 20 % of patients with higher SYNTAX score as against 1.4 % in those with lower SYNTAX score (p 0.001). CONCLUSIONS Interarm blood pressure difference of ≥ 10 mm of Hg is seen in 16 % of cases taken up for coronary angiogram. Patients with IAD ≥ 10 mm of Hg had higher SYNTAX score of ≥ 22 suggesting more complex coronary artery disease. KEYWORDS Interarm Blood Pressure Difference, SYNTAX Score

The Relationship

Objectives. The inter-arm systolic blood pressure difference (IASBPD) is closely related to cardiovascular mortality and morbidity. The SYNTAX score indicates the extent and complexity of coronary artery disease, which are determined by coronary angiography. The aim of our study is to examine the relationship between the IASBPD (which is easily calculated in routine practice) and the SYNTAX score. Methods. 104 patients were included in this cross-sectional study. The IASBPD was calculated by blood pressure measurements obtained simultaneously from both arms. The SYNTAX score was calculated by coronary angiography. Results. Patients were divided into two groups: those with a high SYNTAX score (≥20) and those with a low SYNTAX score (<20). The mean IASBPD values were significantly higher in the group with a high SYNTAX score (≥20) (p<0.001). The patients with IASBPD≥10 were more likely to have a high SYNTAX score compared to the patients with IASBPD<10 (p<0.001). Multiple logistic regression analysis revealed that only the IASBPD values were found to be independently associated with high SYNTAX score (OR: 1.717 (CI: 1.307-2.257), p<0.001). Conclusion. The IASBPD values obtained by only blood pressure measurements are closely related to the extent of coronary artery disease.

Background. Systolic interarm differences in blood pressure have been associated with all-cause mortality and cardiovascular disease. We investigated the relationship between interarm systolic blood pressure difference and coronary artery disease. Methods. We retrospectively analyzed data for patients undergoing coronary angiography and brachial-ankle pulse wave velocity examination during hospitalization from 2013 to 2018. Patients underwent simultaneous upper arm blood pressure measurement. Interarm systolic blood pressure difference (IASBPD) was defined as the absolute value of the difference between the right and left upper limb systolic blood pressure. Patients with IASBPD ≥10 mmHg constituted the high group, and those with IASBPD <10 mmHg constituted the normal group. We also recorded data for cardiovascular risk factors. Coronary artery disease was defined as ≥50% vessel stenosis or having undergone interventional therapy according to coronary angiography results. Results. Compared with the normal group, the number of patients with coronary artery disease was higher in the high group (86.1% vs. 74.6%, P = 0.029 ). Multiple logistic regression showed that IASBPD ≥10 mmHg were positively correlated with coronary artery disease (odds ratio, 2.313; 95% confidence interval, 1.086–4.509; P = 0.029 ), and as the IASBPD value increased, the correlation also gradually increased. Conclusions. IASBPD ≥10 mmHg was positively related to coronary artery disease and increased IASBPD values were correlated with coronary artery disease severity.

The Relationship

Aim. Peripheral vascular disease (PVD) and coronary artery disease (CAD) are, in many cases, asymptomatic and not usually diagnosed. The timely diagnosis of peripheral vascular diseases can act as an indicator or practical evidence of CAD. Therefore, this study was conducted to determine the relationship between interarm systolic blood pressure difference (IASBPD) and severity and number of coronary artery stenosis. Methods. The samples in this cross-sectional study consisted of 578 patients who were candidates for coronary angiography, with an average age of 57.5 ± 10.5 years. Patients were classified according to CAD and number and severity of coronary artery stenosis. The relationship between IASBPD and presence or lack of CAD as well as the number and severity of coronary artery stenosis was studied. The sensitivity, specificity, and positive predictive value of IASBPD index were calculated for the detection of CAD using the Kappa coefficient. Results. There was no statistically significant relationship between IASBPD, CAD, and severity and number of coronary artery stenosis. This index had low sensitivity and predictive value in the diagnosis of CAD and stenosis in coronary arteries in comparison with angiography. Conclusion. The results showed that the IASBPD index cannot be a valid criterion for the diagnosis of CAD as well as the number and severity of coronary artery stenosis. More studies with larger sample sizes and different designs are needed in this regard to achieve more conclusive results.

Background: Epicardial fat increase has not yet a clear correlation with coronary artery disease (CAD). Aim: This study had as goal to demonstrate a relationship between an increase of epicardial fat thickness (EFT) and CAD. Materials & methods: In this observational study, we included 234 patients who underwent invasive coronary angiography. Before invasive coronary angiography, all patients underwent echocardiographic-2D for evaluation of EFT and they were divided into groups based on Gensini score and also on Syntax score. Results: EFT was significantly correlated to the presence and severity of CAD assessed by Gensini score with a cut-off value of 5.2 mm (sensitivity of 90.9%-specificity of 87.3%- area under the ROC curve = 92.1%). Conclusion: EFT increase (fat index ≥5.2 mm) evaluated by echocardiographic-2D could be considered as a risk factor for predicting CAD.

Abstract Background Coronary artery disease (CAD) represents a leading cause of death worldwide. Coronary angiography represents the gold standard for diagnosis and selection of the best treatment for the patients with coronary artery disease; however some efforts have been made to predict CAD severity and complexity using non-invasive methods in order to identify the patients at high risk for cardiovascular events with less risk to the patients and before doing coronary angiography. Characterization of coronaryartery calcification by computed tomography known as Coronary artery calcium score (CACS) is equivalent to the total coronary atherosclerosis load and is proven to be related to angiographically significant lesions. Echocardiographic calcium score is now validated against non-coronary calcium by computed tomography with lower cost and no irradiation safety issues for reclassification of cardiac risk. Aim and Objectives to determine the correlation of echocardiography calcium score to severity of coronary artery disease. Patients and Methods Patients coming to Ain Shams University Hospitals for elective coronary angiography were subjected to histoty taking, examination, blood samples and echocardiographic examination. The echocardiographic calcium score was correlated with syntax score of their coronary angiography films. Also syntax score was divided into three groups; low risk ≤ 18, intermediate risk 18-27 and high risk groups &gt;27. Results The study included 45 patients; 21 of which were males representing 46.6% of the participants. The mean age of the whole group was 52.7 ± 8.18. The mean final calcium score of the whole study group was 4.95±1.29. The mean syntax score of the whole study group was 22.88±12.3. There was significant difference between the three subgroups of the syntax score regarding total calcium score (p value 0.013) and highly significant difference between the numerical values of syntax score and final calcium score. Conclusion Echocardiographic calcium score is correlated to syntax score and the severity of coronary artery disease. The low cost, availability and the radiation free nature of echocardiography make it an attractive candidate for the on-going research regarding the non-invasive tools for prediction of CAD.
