Coronary Artery Patterns in Diabetic Patients Undergoing Diagnostic Coronary Angiography-Data from a Major Cardiac Center in Yemen

Background: Diabetes mellitus (DM) is independently associated with an increased risk of cardiovascular mortality and morbidity, including coronary artery disease (CAD). CAD is a shared burden disease and the leading cause of death in developed and developing countries. We aimed to assess the angiographic patterns of coronary arteries in patients with DM in a developing country (Yemen) as the first study. Methods: This study is a cross-sectional, prospective, observational study that includes a total of 250 patients who were admitted for elective diagnostic coronary angiography. Results: 96 (38.4%) patients were diabetics;68% were male;mean age was 57 ± 11 years. The incidence of three-vessel disease was 31.2% of patients. Considering the severity of lumen occlusion, (11.2%) of patients had non-significant lesions, (37.6%) of patients had significant lesions, and (32%) had total occlusive lesions. Lesions were of LAD in 76%, RCA in 60%, and LCX in 52% of the population. Among diabetics, two and 3-vessel diseases (33.3% vs. 20.8% & 50% vs. 19.5%, P = 0.001), left main lesion (10.4% vs. 2.6%, P = 0.012), significant stenosis (41.7% vs. 35.1%, P = 0.032), total occlusion of coronary arteries (43.8% vs. 19.5%, P = 0.032) and type C lesion (66.7% vs. 35.1%, P = 0.010) were more frequent than non-DM patients. Conclusion: The burden of significant and severe coronary lesions is more common among DM, which may be the major cause of morbidity and mortality of DM in developing countries.

High Prevalence of Anatomical Variations and Anomalies of the Coronary Arteries Detected by CT Angiography in Symptomatic Patients

Objective:Coronary artery anatomical variations and anomalies are an important topic due to their potential clinical manifestations.This study aims to investigate the prevalence of coronary artery anatomical variations and anomalies in symptomatic patients with coronary computed tomography angiography(CCTA).Methods:This is a retrospective study that included all symptomatic patients who had CCTA in a tertiary care hospital in Saudi Arabia during a period of seven years.Results:The total number of included patients was 507(60%males)with a mean age of 57.4 years.Approximately 41%had luminal stenoses,averaging 49.7%.The total num-ber of patients with coronary anatomical variations(CAV)and coronary artery anomalies(CAA)was 217(43%).CAV prevalence was 26%,which included 14%non-right coronary dominance,5%short left main coronary artery(LMCA),and 7%division variations(trifurcation and quadrifurcarion)of the LMCA.The prevalence of CAA was 29%,which included 5%origin anomalies,22%myocardial bridge,and 2%course anomalies.Conclusions:A high prevalence of coronary artery anatomic variations and anomalies in symptomatic patients is reported in this study.Systematic reviews,meta-analyses,reporting guidelines,and unified definitions and classifications of cor-onary variations and anomalies are lacking in the literature,presenting potential opportunities for future research and publications.

R-I subtype single right coronary artery with congenital absence of left coronary system: A case report

BACKGROUND Isolated single coronary artery is a rare congenital anomaly.R-I subtype single coronary artery is even rarer.In this subtype,a very large right coronary artery extends in the coronary sulcus to the anterior base of the heart where it produces the left anterior descending coronary artery.Currently,only a few case reports are available in the literature for this anomaly.CASE SUMMARY Here,we report the case of a 62-year-old woman who presented to the cardiology clinic with decreased exercise tolerance and poor blood pressure control.The patient underwent coronary angiography(CAG)and emission computed tomography(ECT).CAG images revealed a single gigantic right coronary artery(R-I type)arising from the right coronary sinus with branches supplying the left coronary territory.The ECT results confirmed myocardial ischemia at the location of the absent left coronary artery.The ECT findings confirmed that ischemia was consistent with the vascular loss location in CAG images.In such anomalies,there is a compensatory widening of the coronary artery lumen.Medical treatment was administered,and the patient was discharged.CONCLUSION Isolated single coronary arteries are associated with ischemia and potentially fatal acute coronary events.Hence,controlling risk factors is critical.

Emerging role of computed tomography coronary angiography in evaluation of children with Kawasaki disease

Coronary artery abnormalities are the most important complications in children with Kawasaki disease(KD).Two-dimensional transthoracic echocardiography currently is the standard of care for initial evaluation and follow-up of children with KD.However,it has inherent limitations with regard to evaluation of mid and distal coronary arteries and,left circumflex artery and the poor acoustic window in older children often makes evaluation difficult in this age group.Catheter angiography(CA)is invasive,has high radiation exposure and fails to demonstrate abnormalities beyond lumen.The limitations of echocardiography and CA necessitate the use of an imaging modality that overcomes these problems.In recent years advances in computed tomography technology have enabled explicit evaluation of coronary arteries along their entire course including major branches with optimal and acceptable radiation exposure in children.Computed tomography coronary angiography(CTCA)can be performed during acute as well as convalescent phases of KD.It is likely that CTCA may soon be considered the reference standard imaging modality for evaluation of coronary arteries in children with KD.

Diagnostic Accuracy of Three-Dimensional Whole-Heart Magnetic Resonance Angiography to Detect Coronary Artery Disease with Invasive Coronary Angiography as a Reference:A Meta-Analysis

Objective:We aimed to evaluate the diagnostic performance of three-dimensional whole-heart magnetic resonance coronary angiography(MRCA)in detecting coronary artery disease(CAD)with invasive coronary angiography as the reference standard.Methods:We searched PubMed and Embase for studies evaluating the diagnostic performance of three-dimensional whole-heart MRCA for the diagnosis of CAD with invasive coronary angiography as the reference standard.The bivariate mixed-effects regression model was applied to synthesize available data.The clinical utility of whole-heart MRCA was calculated by the posttest probability based on Bayes’s theorem.Results:Eighteen studies were included,of which 16 provided data at the artery level.Patient-based analysis revealed a pooled sensitivity of 0.90(95%confi dence interval[CI]0.87–0.93)and specifi city of 0.79(95%CI 0.73–0.84),while the pooled estimates were 0.86(95%CI 0.82–0.89)and 0.89(95%CI 0.84–0.92),respectively,at the artery level.The areas under the summary receiver operating characteristic curve were 0.93(95%CI 0.90–0.95)and 0.92(95%CI 0.90–0.94)at the patient and artery levels,respectively.With a pretest probability of 50%,the patients’posttest probabilities of CAD were 81%for positive results and 11%for negative results.Conclusions:Whole-heart MRCA can be an alternative noninvasive method for diagnosis and assessment of CAD.

Spontaneous coronary artery dissection-associated takotsubo syndrome: A systematic review of case reports

BACKGROUND Spontaneous coronary artery dissection(SCAD)is underdiagnosed and requires comprehensive angiographic findings.Few SCAD occurrences have a comparable clinical appearance as takotsubo syndrome(TTS)or exist simultaneously,making it challenging for clinicians to treat and manage.Case reports lack consolidated AIM To conduct a systematic review of available case reports on SCAD in order to investigate its potential association with TTS.METHODS SCAD-associated TTS case reports were reviewed after thoroughly screening PubMed,EMBASE,Scopus,and Google Scholar databases till January 2023.Case reports described demographics,comorbidities,imaging,management,and results.RESULTS Twelve articles about 20 female patients were analyzed.30%of patients(n=6,>60 years)were elderly(mean age 56.2±9.07 years,range 36-70 years).Canada has 9 cases,United States 3,Australia 3,Sweden 2,Japan,Denmark,and France 1.Only 5 reports identified emotional stressors in these cases while 4 reports showed physical triggers for TTS.Nine had hypertension,2 had hyperlipidemia,and 1 had prediabetes.5 patients(25%)smoked.10(50%)troponin-positive myocardial infarction patients reported chest discomfort.11(55%)of 20 instances had TTS/SCAD.12(60%)of 20 patients exhibited ST elevation and 3(15%)had T wave inversion on electrocardiogram.19/20 patients had elevated troponin.9(45%)of 20 people had apical akinesis with TTS ballooning on cardiac imaging.All 20 exhibited echocardiographic wall motion abnormalities.19(95%)of 20 coronary angiography cases had SCAD.10 of 19 SCAD patients had left anterior descending,2 diagonal,and 2 left circumflex coronary artery involvement.7 of 20 patients had left ventricular ejection fraction(LVEF)data.LVEF averaged 38.78±7.35%.5(25%)of the 20 cases underwent dual antiplatelet therapy.Three(15%)of 20 cases experienced occasional ectopic ventricular complexes,Mobitz ll AV block,and paroxysmal atrial fibrillation.All 20 cases recovered and survived.CONCLUSION Given the clinical similarities and challenges in detecting TTS and SCAD,this subset needs more research to raise awareness and reduce morbidity.

Anxiety, Depression and Coronary Artery Disease among Patients Undergoing Angiography in Ghaem Hospital, Mashhad, Iran

The prevalence of coronary artery disease (CAD) is increasing in Iran. Patients with depression who have a myocardial infarction are more likely to die and patients who have depressive symptoms during hospitalization may have increased cardiovascular events. This study aimed to determine the relationship between anxiety, depression and coronary artery disease among patients undergoing angiography in Ghaem Hospital, Mashhad. This was a case-control study conducted between September 2011 and August 2012 among patients undergoing coronary angiography in Ghaem Hospital, Mashhad, Iran. There were 486 cases that were found to have one or more coronary stenoses, with a stenosis of equal or more than 50% of the diameter of at least one major coronary artery. The other patient group consisted of the patients in whom the coronary artery stenosis was less than 50% in diameter which was classified as angiography negative, and a control group that consisted of 440 healthy adults aged 18 years old and above who were selected among people who attended for routine medical checkup and medical examination of employment. The dependent variables were Beck Anxiety and Depression Inventory scores and the independent factors were coronary artery disease, and socioeconomic profiles. Validated and reliability-tested questionnaires were used for data collection. The mean age of patients was 55.75 ± 10.64 years and in the healthy group was 55.83 ± 8.55 years;there was no significant difference in age between subject groups (p = 0.897) nor a significant difference in the gender frequency distribution of subjects (p = 0.610). There was a significant difference in anxiety score between the Angio positive and Angio negative patients and healthy control subjects

Radiation dose analysis of computed tomography coronary angiography in Children with Kawasaki disease

BACKGROUND There is evolving role of computed tomography coronary angiography(CTCA)in non-invasive evaluation of coronary artery abnormalities in children with Kawasaki disease(KD).Despite this,there is lack of data on radiation dose in this group of children undergoing CTCA.AIM To audit the radiation dose of CTCA in children with KD.METHODS Study(December 2013-February 2018)was performed on dual source CT scanner using adaptive prospective electrocardiography-triggering.The dose length product(DLP in milligray-centimeters-mGy.cm)was recorded.Effective radiation dose(millisieverts-mSv)was calculated by applying appropriate age adjusted conversion factors as per recommendations of International Commission on Radiological Protection.Radiation dose was compared across the groups(0-1,1-5,5-10,and>10 years).RESULTS Eighty-five children(71 boys,14 girls)with KD underwent CTCA.The median age was 5 years(range,2 mo-11 years).Median DLP and effective dose was 21 mGy.cm,interquartile ranges(IQR)=15(13,28)and 0.83 mSv,IQR=0.33(0.68,1.01)respectively.Mean DLP increased significantly across the age groups.Mean effective dose in infants(0.63 mSv)was significantly lower than the other age groups(1-5 years 0.85 mSv,5-10 years 1.04 mSv,and>10 years 1.38 mSv)(P<0.05).There was no significant difference in the effective dose between the other groups of children.All the CTCA studies were of diagnostic quality.No child required a repeat examination.CONCLUSION CTCA is feasible with submillisievert radiation dose in most children with KD.Thus,CTCA has the potential to be an important adjunctive imaging modality in children with KD.

Prevalence and Predictive Factors of Severe Coronary Lesions in Algerian Patients Undergoing Coronary Angiography

Background: The severity of coronary lesions in patients with coronary artery disease (CAD) has important prognostic and therapeutic consequences. Clinical symptoms not always reflect the disease severity and this study aimed to evaluate coronary lesions in the Algerian population where these data are scarce. Methods: It was a prospective cross-sectional study conducted in consecutive patients with an age ≥20 years who underwent clinically-indicated coronary angiography in our center. The objective of the study was to determine the prevalence of severe coronary lesions assessed with the Gensini score. The predictive factors of severity were evaluated in a multivariate analysis. Results: A total of 507 patients were included (male, 79.7%;mean age, 58.8 years). Coronary angiography was prescribed most frequently for ST-segment elevation myocardial infarction (STMI) (46.9%) and non-STMI (38.1%). The prevalence of severe coronary lesions was 69.6% (95% CI 65.5 - 73.5). In multivariate analysis, the independent predictive factors of severe coronary lesions were male sex (odds ratio [OR] 2.00;p = 0.0141), diabetes (OR 1.92;p = 0.0070), left ventricular dysfunction (OR 1.81;p = 0.0059), age (OR 1.72;p = 0.0297) and no lipid-lowering treatment (OR, 0.47;p = 0.0388). Conclusions: Severe coronary lesions were present in two out three patients in this cohort of Algerian patients undergoing coronary angiography. Independent predictive factors of severe coronary lesions were male sex, diabetes, age, left ventricular dysfunction and no lipid-lowering treatment. It is important to identify these at-risk patients, as they should be explored at an asymptomatic stage before a cardiovascular event and receive prompt treatment with angioplasty or surgery.

Imaging Effect and Accuracy Analysis of 64-Slice Spiral CT in the Diagnosis of Coronary Artery Stenosis

Objective:To analyze the imaging effect and accuracy of 64-slice spiral CT in the diagnosis of coronary artery stenosis.Methods:30 patients with suspected coronary heart disease admitted to our hospital from March 2022 to March 2023 were selected.All patients underwent both 64-slice spiral CT and digital subtraction angiography(DSA).DSA is considered the gold standard for diagnosis,so it was used to analyze the diagnostic performance of 64-slice spiral CT.Results:(1)The diagnostic results of digital subtraction angiography and 64-slice spiral CT was analyzed and compared with each other.The 64-slice spiral CT had an accuracy of 96.67%(29/30),a sensitivity 96.55%(28/29),and a specificity of 100.00%(1/1)in diagnosing coronary artery stenosis.(2)There was no significant difference between 64-slice spiral CT and digital subtraction angiography in the positive detection rate of anterior descending artery lesion,the positive detection rate of left main lesion,the positive detection rate of left circumflex artery lesion and the positive detection rate of right coronary artery lesion(P>0.05).(3)There was no significant difference between 64-slice spiral CT examination and DSA examination in identifying mild stenosis,moderate stenosis,and severe stenosis of coronary arteries(P>0.05).Conclusion:64-slice spiral CT examination can accurately determine the degree of occlusion of coronary arteries,which allows for the accurate diagnosis of coronary artery stenosis.

Noninvasive Detection of Coronary Artery Stenosis Using 16-slice Spiral CT: a Comparison with Selective X-ray Coronary Angiography

The role of 16-slice spiral CT was selective X-ray coronary angiography （SCA） who were suspected of having coronary heart evaluated in the diagnosis of coronary stenosis, with serving as the reference standard. Sixty-five patients disease, without percutaneous transluminal coronary angioplasty or coronary bypass-grafting, were investigated using 16-slice CT. Eight patients with pre-scan heart rate of more than 80 beats/min were given β-blockers. After the retrospectively ECG-gated axial imaging reconstruction, volume redering （VR）, multi-planar reconstruction （MPR）, curved MPR and maximum intensity projection （MIP） were used to reconstruct. Every segment of coronary artery with a diameter ≥1.5 mm was assessed, and the presence on CT with a stenosis exceeding 50 % diameter reduction was compared with that on SCA. The reasons which lead to some segments unevaluable were analysed. Compared with SCA, 93 % coronary segments and 94 % main branches were evaluable. Residual cardiac motion artifacts, severe calcification and poor opacification made 58 %, 28 % and 14 % of the remaining 60 segments unevaluable respectively. Without routine administration of β-blockers, good coronary imaging quality can be acquired using 16-slice spiral CT. It is a reliable noninvasive method for detection of obstructive coronary artery disease.

Non-obstructive coronary artery disease and cardiovascular events in patients with angina-like chest pain detected by coronary angiography:a Chinese cohort study

Objective The utility of non-obstructive coronary artery diseases(NOCAD) in cardiovascular events (CVE) among Chinese patients has less been evaluated. Our objective was to investigate the prognostic value of NOCAD in patients with angina-like chest pain detected by coronary angiography (CAG) in a large Chinese cohort study.

Association between LDL, Apolipoprotein-B Apolipoprotein A-I and Lipoprotein(a) and Severity of Coronary Artery Disease Based on Coronary Angiography

Atherosclerosis is the most important contributor to increasing burden of coronary artery disease (CAD). Growing evidence suggests that the ratios of Apo B/Apo A-I and Lp(a) are better indexes for risk assessment of CAD. Elevated plasma levels of lipoprotein(a) in humans represent a major in-herited risk factor for atherosclerosis. Thus, a study was performed to determine the association betwwen serum Apo B, Apo A-I, and lipoprotein(a) levels, and severity of CAD in patients with CAD confirmed on coronary angiography findings. An analytical case control study was carried out with 85 patients (58 males and 27 females) 40 - 60 years of age confirmed as having CAD on coronary angiography and 85 age and sex matched healthy volunteers as controls. Serum samples were an-alyzed for Apo A-1 LDL, Apo B, Apo A-I, and lipoprotein(a) concentration and the severity of CAD was assessed using coronary angiography scoring method. Patients with CAD had significantly high serum LDL-C, Apo B and Lp(a) levels compared to control subjects. However, serum Apo A-I level did not show a significant difference between two groups. Subjects with a positive family history of CAD with increased serum Lp(a) ≥ 17.3 mg/dL have high risk for development of CAD. Present study suggests that serum Lp(a) cut-off value of 17.3 mg/dL may be an important predictor in ruling out major vessel disease and luminal narrowing by atheroma.

Comparison of Clinical Value between Right Distal Radial Artery Access and Right Radial Artery Access in Patients Undergoing Coronary Angiography or Percutaneous Coronary Intervention

Objective:To compare the feasibility and safety between right distal radial artery access and right radial artery access in patients undergoing coronary angiography(CAG)or percutaneous coronary intervention(PCI).Methods:On the basis of arterial access,113 patients who underwent CAG or PCI in Kunshan Hospital of Traditional Chinese Medicine between January and October 2018 were divided into two groups:a right distal radial artery group(52 patients)and a right radial artery group(61 patients).We collected general information,the number of puncture attempts,access times,postoperative compression time,and complications.Results:The general characteristics,rate of successful radial artery puncture,and rate of successful catheter placement in the two groups were not different.The right radial artery group had fewer puncture attempts(1.26±0.44 times vs.2.19±0.53 times,P=0.001)and a shorter access time(3.23±0.86 min vs.4.77±1.49 min,P=0.001)than the right distal radial artery group.However,the postoperative compression time in the right distal radial artery group was shorter(3.44±0.9 h vs.7.16±1.21 h,P=0.001).Two cases of bleeding,four cases of hematoma,and one case of artery occlusion in the right radial artery group and one case of hematoma in the right distal artery group occurred before discharge.The rate of total complications in the right distal radial artery group was lower than in the right radial artery group(1.93%vs.11.48%,P=0.048).Conclusion:CAG or PCI through the right distal radial artery is feasible and safe.

Arterial Supply of Atrioventricular Node and Bundle in Relation to Degree of Stenosis of Coronary Artery among Sudanese Population (Coronary Angiography Study)

The coronary arteries diseases are one of the most causes of mortality and morbidity worldwide, particularly in the developing countries. Coronary obstructions are generally described by location and severity of stenosis. Manual tracing and measurement of the stenosis vessel in comparison to reference location of stenosis can be helpful to classify whether a lesion is significant or not. The aim of this study is to identify the dominant type of circulation carried out in patients presented in heart institute and associated with degree of stenosis in RCA and LAD artery. Materials and Methods: This was a retrospective study carried out on patients reporting to Heart Institute from June 2013 to August 2013 (311 patients records as a total coverage were collected as sample) whose coronary artery angiography revealed pathology in coronary arteries. Result: The findings were 71.7% right dominant, 23.5% left dominant and 4.8% co-dominant;LAD tends to be stricture with right dominant circulation type. LAD artery tends to be stenosis at proximal and mid segment while in the RCA tends to be stenosis in mid and distal segments. The right dominant artery is popular type of circulation in Sudanese people reported in Sudan Heart Institute;there is no significance association between gender and arterial type of circulation and also degree stenosis in LAD degree of stenosis in RCA. I observed that the site of stenosis in LAD artery was proximal and mid (P value < 0.05 significance association). Conclusion: Patients present at the heart institute are right dominant mostly coming with proximal and middle LAD stenosis unlike RCA which commonly presents with distal and middle stenosis, so the middle segment of coronary artery is stenosis in both situations. There are wild variations in dominance artery in relation to reduction of diameter in deferent ethic group. There are no significant associations between the gender and dominant artery.

Abnormal coronary artery angiography is not associated with adverse pregnancies outcomes

Background: Recently, epidemiologic studies have suggested an association between pregnancy complications and the development of coronary artery disease later in life. The current study investigate the relation between obstructive coronary versus normal coronary angiographies and the prevalence of complications during pregnancy including preeclampsia, pregnancy induced-hypertension, low birth weight, and preterm birth. Methods: All consecutive women aged <55 year, who had coronary angiography were included. Based on angiography outcome, patients were classified as normal (controls: no stenosis, wall irregularity without stenosis, or minimal calcification present) or abnormal (subjects). A standard questionnaire was sent to all participating women. The questionnaires inquired into risk factors for coronary vascular disease, in particular history of hypertensive diseases, and specific obstetric history. The results were analyzed using the unpaired t-test, the Chi-squared test, and Pearson’s correlation coefficients as appropriate. A significance level of P < 0.05 was used. Results: Of the 211 consecutive women aged <55 year, 62% (n = 131) had normal coronary angiography and 38% (n = 80) abnormal coronary angiography. We found no differences of reported pregnancy complications including preeclampsia, hypertension, low birth weight, and preterm birth (combined RR = 0.70, 95% C.I. = 0.38 - 1.3) in case of abnormal coronary angiography compared to women with normal coronary angiography. The traditional risk factors hypercholesterolemia, tobacco use, and diabetes were identified as the major risk factors for developing cardiovascular disease, with a relative risk ranging from 4.2 - 1.8. Conclusion: These data suggest that pregnancy complications are not an important denominator for cardiovascular disease.
