Abstract Background Although the incidence of myocardial bridge (MB) has been defined in different femoral access conventional coronary angiography (FACCA) studies, the frequency of MB on radial access coronary angiography (RACA) is unknown. The aim of this study was to determine the difference in the incidence of MB between patients undergoing RACA and FACCA. Method A total of 2500 consecutive patients who underwent RACA and a total of 1455 consecutive patients who underwent FACCA were retrospectively investigated to detect the presence of MB. The incidences of the groups were calculated separately and compared. The clinical and angiographic features of the patients with MB were analyzed. Results MB was detected at an incidence of 10.2%, in 255/2500 patients who underwent RACA, and 1.8% in 27/1455 patients who underwent FACCA (p < 0.001). In both RACA and FACCA patients, the most involved coronary artery was the left anterior descending artery (LAD) (86.9% and 93.1%) and the mid-segment (84.9% and 88.9%) was the most affected section. Co-involvement of multiple coronary arteries by MB was 7.8% in patients who underwent RACA and 7.4% in patients who underwent FACCA. Coronary artery disease (CAD) was determined in 111 (35.7%) of the coronary arteries with MB, of which 81.9% were proximal to the MB. No significant CAD was detected in any of the vessels of 69.8% (178/255) of the patients who underwent RACA for different clinical indications. Conclusion These data demonstrated that the incidence of myocardial bridge able to be detected on RACA was much higher than FACCA.

Abstract Background Anemia is a frequent comorbidity in patients with coronary artery disease (CAD). Besides a complemental effect on myocardial oxygen undersupply of CAD and anemia, available data suggests that it may independently impact the prognosis in CAD patients. We aimed to determine the association of anemia with long-term survival in a longitudinal registry of patients undergoing conventional coronary angiography. Methods The present analysis is based on the ECAD registry of patients undergoing conventional coronary angiography at the Department of Cardiology and Vascular Medicine at the University Clinic Essen between 2004 and 2019. For this analysis, we excluded all patients with missing hemoglobin levels at baseline admission or missing follow-up information. Anemia was defined as a hemoglobin level of &lt;13.0g/dl for male and &lt;12.0g/dl for female patients according to the world health organization's definition. Cox regression analysis was used to determine the association of anemia with morality, stratifying by clinical presentation of patients. Hazard ratio and 95% confidence interval are depicted for presence vs. absence of anemia. Results Overall, data from 28,917 patient admissions (mean age: 65.3±13.2 years, 69% male) were included in our analysis (22,570 patients without and 6,347 patients with anemia). Prevalence of anemia increased by age group (age &lt;50 years: 16.0%, age ≥80 years: 27.7%). During a mean follow-up of 3.2±3.4 years, 4,792 deaths of any cause occurred (16.6%). In patients with anemia, mortality was relevantly higher as compared to patients without anemia (13.4% vs. 28.0% for patients without and with anemia, respectively, p&lt;0.0001, figure 1). In univariate regression analysis, anemia was associated with 2.4-fold increased mortality risk (2.27–2.55, p&lt;0.0001). Effect sizes remained stable upon adjustment for traditional risk factors (2.38 [2.18–2.61], p&lt;0.0001). Mortality risk accountable to anemia was significantly higher for patients receiving coronary interventions (2.62 [2.35–2.92], p&lt;0.0001) as compared to purely diagnostic coronary angiography examinations (2.31 [2.15–2.47], p&lt;0.0001). Likewise, survival probability was slightly worse for patients with anemia in acute coronary syndrome (2.70 [2.29–3.12], p&lt;0.0001) compared to chronic coronary syndrome (2.60 [2.17–3.12], p&lt;0.0001). Interestingly, within the ACS entity, association of anemia with mortality was relevantly lower in STEMI patients (1.64 [1.10–2.44], p=0.014) as compared to NSTEMI and IAP (NSTEMI: 2.68 [2.09–3.44], p&lt;0.0001; IAP: 2.67 [2.06–3.47], p&lt;0.0001). Conclusion In this large registry of patients undergoing conventional coronary angiography, anemia was a frequent comorbidity. Anemia relevantly influences log-term survival, especially in patients receiving percutaneous coronary interventions. Our results confirm the important role of anemia for prognosis in patients with coronary artery disease, demonstrating the need for specific treatment options. Figure 1.

Myocardial bridge(MB) is an anatomical variant. Sometimes MB can cause compression over the coronary arteries and causes ischemic heart diseases.MB associated with bends of coronary arteries double the risk of coronary artery disease. So the present study aimed to find out the incidence of bends of the coronary artery along with the myocardial bridging. 100 heart specimens were obtained from routine dissection conducted for undergradu­ate students in the department of Anatomy IMS & SUM Hospital Bhubaneswar. After the simple dissecting procedure, epicardial coronary arteries, their branches and myocardial bridges and hairpin bends of coronary arteries were observed. Myocardial bridges present 41 (41%) over Left anterior descending artery(LAD) only.Among 41 hearts single myocardial bridge present in 37((90.25%)  hearts, double myocardial bridge were present in 3((7.31%)  hearts and triple myocardial bridges present in only one heart(2.44%). Hairpin bends of the coronary artery were present in double and triple myocardial bridged hearts only. No hairpin bends of the coronary artery was observed in the single myocardial bridge. Hair pin bends of the coronary arteries are the unique features of the myocardial bridges in multiple myocardial bridges, i.e. double and triple myocardial bridges. However, hairpin bends of coronary arteries were absent in single myocardial bridged hearts.

Myocardial Infarction with Non-obstructive Coronary Arteries-MINOCA is a clinical syndrome that encompasses a subgroup of heterogeneous patients who present with myocardial infarction yet do not have any significant coronary artery obstruction on angiogram. From several studies it is understood that MINOCA has a 8.8% prevalence of all Myocardial Infarction (MI) presentations, with no characteristic distinguishing clinical features when compared with MI-CAD( Coronary artery disease), except for patients being younger with a female preponderance & less likely to have hyperlipidemia. The prognosis is extremely variable, depending on the causes of MINOCA. Clinical history, echocardiography, coronary angiography, and left ventriculography represent the first-level diagnostic investigations. Ibrahim Card Med J 2015; 5 (1&2): 61-66

Background. Coronary artery ectasia (CAE) occurs in 0.3 to 5.3% of patients undergoing coronary angiography. TIMI frame count (TFC) is an index of coronary flow that correlates with flow velocity. In ectasia patients, there is delayed coronary flow with increased TFC.Methods.We evaluated angiograms of 789 patients for presence of CAE, coronary artery disease (CAD), and Markis type of CAE. We measured ectasia size and length and their correlation with TFC in ectatic right coronary arteries (RCA) of patients with CAE and CAD.Results.30 patients had CAE (3.8%). Of these 16.7% had isolated CAE, while 83.87% had CAE and CAD. Among CAE and CAD patients, the RCA was most involved (70.4%), and Markis type IV CAE was the commonest (64%). In isolated CAE, the RCA, LAD, and LCx were equally involved (33.3%). Patients with CAE and CAD had significantly higher TFC compared to controls,P=0.035. There was a positive correlation of moderate strength, between ectasia size and TFC,r(17) = 0.598,P=0.007. Ectasia length was not significantly correlated with TFC, rho (17) = 0.334,P=0.163.Conclusion.Among patients undergoing angiography, CAE has a prevalence of 3.8% and Markis type IV is the commonest. Larger ectasias are associated with slower coronary flow.

Background: Coronary artery disease (CAD) morbidity and mortality increasing day by day in India as well as worldwide. Coronary arteries visualization by using invasive catheterization angiography is still using as a front-line diagnostic tool to evaluate the patients with CAD. 128 slice dual source CT improves the cardiac imaging such as high scanning speed, good temporal resolution and low radiation dose. Objective: To assess the diagnostic accuracy of 128-slice dual source CT cardiac angiography with conventional catheter angiography to find common arteries involved in CAD. Methods: This is a prospective, comparative, cross sectional study conducted at cardiology OPD. Patients with complaint of chest pain and suspected CAD were evaluated by CT and conventional coronary angiography and results were compared. Serum creatinine and ECG status were analyzed before the angiography. SIEMENS 128-slice Dual Source Flash Definition CT Scanner was used as a CT coronary angiography. Severity distribution of coronary artery disease, artery wise distribution of non-significant, significant lesions and coronary artery dominance pattern were analyzed and compared. Results: A total of 70 suspected CAD patients were selected and analyzed. American Heart Association (AHA) model of 17-segment was used to assess the coronary arteries. Normal angiograms reported in 15.71% patients and 58.57% had significant disease. A total of 356 lesions were identified from 690 out of 720 segments. Right coronary artery (RCA) is the most common location of significant lesions which contributes 33.5% (n=55/164). Coronary circulation of right-sided dominance was most commonly reported (70.0%). CT angiography showed 96.13% of an overall sensitivity, 96.28% specificity, 89.72% positive predictive value and 98.49% negative predictive value. Conclusion: 128-slice dual source CT scanner has showed high accuracy and act as non-invasive assessment of coronary arteries in patients with CAD Keywords: Cardiac angiography, Catheter coronary angiography, CT coronary angiography, 128-slice MDCT, Conventional angiography
