Two Cases of Combined Performance of Endovascular Aortic Aneurysm Repair (EVAR) and Off-Pump Coronary Artery Bypass Grafting (OPCAB) / 日本心臓血管外科学会雑誌

Concomitant occurrence of coronary arterial disease (CAD) with abdominal aortic aneurysm (AAA) is not rare. Combined performance of open surgery (OS) of AAA repair and coronary arterial bypass grafting (CABG) has been reported to be effective as the way to avoid the risk of rupture of the aneurysm and acute coronary syndrome (ACS), while it's highly invasive. We successfully performed a combination performance of endovascular aneurysm repair (EVAR) and off-pump CABG (OPCAB) with the support of an intra-aortic balloon pump (IABP) in 2 cases with AAA and unstable angina pectoris (UAP). It was suggested that this strategy is a reasonable clinical option for the patient with UAP complicated with large AAA.

Biomarcadores inflamatorios y extensión de aterosclerosis coronaria en pacientes con síndrome coronario agudo: Estudio observacional prospectivo en un hospital general universitario / Circulating markers of inflammation and severity of coronary atherosclerosis in acute coronary syndrome: Prospective observational study in a general university hospital

Resumen Objetivo: Encontrar una relación entre los niveles de proteína C reactiva (PCR) y fibrinógeno, y la extensión de la aterosclerosis en el síndrome coronario agudo. Métodos: Estudio observacional prospectivo, en el que se incluyeron 873 pacientes con síndrome coronario atendidos en un hospital entre 2016 y 2018. Se analizaron niveles de PCR y fibrinógeno, marcadores metabólicos y extensión de la aterosclerosis coronaria. Resultados: No se halló correlación positiva entre los niveles de PCR y fibrinógeno y los marcadores metabólicos, así como tampoco con enfermedad de uno, dos y tres vasos (p 0,829; p 0,810). Conclusiones: Los niveles sanguíneos de PCR y fibrinógeno se relacionan con la tasa de eventos cardiovasculares, pero no se ha podido demostrar que exista relación entre estos y la severidad de la aterosclerosis coronaria.

Abstract Objective: To determine whether there is a relationship between C - reactive protein and fibrinogen levels and the extent of atherosclerosis in acute coronary syndrome. Methods: A prospective observational study was conducted that include 873 patients with coronary syndrome treated in a hospital between the years 2016 and 2018. An analysis was made that included C - reactive protein and fibrinogen levels, metabolic markers, extent of coronary atherosclerosis. Results: No positive correlation was found between the C - reactive protein and fibrinogen levels and the metabolic markers, nor with one, two, or three vessel disease (P=.829; P=.810). Conclusions: Although blood C-Reactive Protein and fibrinogen levels are associated with the rate of cardiovascular events, this study was unable to demonstrate whether there is a relationship between these and the severity of the coronary atherosclerosis.

Marcadores lipídicos en suero y síndrome coronario agudo en pacientes egresados del servicio de cardiología. Hospital Faustino Pérez / Lipid markers in serum and acute coronary syndrome in patients discharged from service of cardiology. Hospital Faustino Pérez

RESUMEN Introducción: las enfermedades cardiovasculares actualmente son la principal causa de muerte en los países industrializados y se espera que también lo sean en los países en vías de desarrollo en el año 2020. Entre ellas la enfermedad arterial coronaria es la manifestación más prevalente, y se asocia a alta morbimortalidad. La ateroesclerosis es su principal génesis y por tanto los trastornos del metabolismo de los lípidos. Objetivo: determinar el perfil lipídico en pacientes egresados por síndrome coronario agudo. Materiales y métodos: se realizó una investigación descriptiva, transversal, correlacional en los pacientes egresados del servicio de cardiología del hospital Faustino Pérez en el período comprendido entre enero y diciembre del 2015. Resultados: se observó un aumento de los lípidos colesterol, triglicéridos, LDL-c, VLDL y Lp (a) en más del 50% de los pacientes estudiados. Los índices de Apo B/Apo A y Col/HDL-c marcaron como indicador de alto riesgo en un 67,5 y 58,75 % respectivamente. La HDL-c considerada como factor protector, resultó disminuida en más del 50% de los pacientes. Conclusiones: se detectó correlación entre el síndrome coronario agudo y trastornos en el metabolismo de los lípidos. Se recomienda realizar estudios observacionales epidemiológicos para determinar la verdadera influencia de estos factores como agente causal de síndrome coronario agudo (AU).

ABSTRACT Introduction: Currently, cardiovascular diseases are the main cause of death in developed countries, and it is believed that they also will be the same in developing countries in 2020 year. Among them, coronary arterial disease is the most prevalent manifestation, and is associated to high morbi-mortality. Atherosclerosis is its most important cause and consequently the disorders of the lipids metabolism. Objective: determining the lipid profile in patients discharged for acute coronary syndrome. Materials and methods: a descriptive, cross-sectional, correlational research was carried out in patients discharged from the service of Cardiology of the hospital Faustino Perez in the period from January to December 2015. Results: it was found an increase of the lipids cholesterol, triglycerides, LDL-c, VLDL and Lp(a) in more than 50 % of the studied patients. The indexes of Apo B/Apo A and Col/HDL-c were high risk indicators in 67.5 and 58.75 % respectively. HDL-c, considered as a protecting factor, was diminished in more than 50 % of the patients. Conclusions: a correlation was found between the acute coronary syndrome and disturbances in the lipids metabolism. We recommend performing epidemiologic, observational studies to determine the real influence of these factors as causal agent of the acute coronary syndrome (AU).

Clinical value of 70 kV combined with low contrast agent CT scan in the diagnosis of pediatric coronary artery disease / 中华放射学杂志

Objective DSA and/or surgery was used as a control to evaluate the image quality, radiation dose and diagnostic efficacy of 70 kV combined with low contrast agent dose and 80 kV dual-source CT scanning of coronary artery. Methods Between Apr, 2012 and Apr, 2017, a total of 150 consecutive pediatrics with suspected or confirmed coronary arterial diseases underwent DSCTCA, and the patients were randomly divided into 3 groups by different scanning protocols. Group A (n=50): 80 kV with 1.5 ml/kg contrast agent;Group B (n=50): 70 kV with 1.5 ml/kg contrast agent;Group C (n=50): 70 kV with 1.0 ml/kg contrast agent. ANOVA was used to compare the differences of subjective coronary arteries image quality between the three groups; The t-test was used to compare the difference in effective radiation dose between the 70 kV group and the 80 kV group; The surgery and/or angiography results were used as gold standard to evaluate the diagnostic efficacy of the three groups. Results All patients underwent DSCTCA successfully and satisfactory diagnostic images were gained . The mean scores of subjective image quality of coronary artery were 3.5±0.7, 3.4±0.6, 3.7±0.8, respectively. There was no significant difference between the 3 groups (F=2.042, P=0.133). The diagnostic accuracy of the three groups for coronary artery disease was 100%, as the surgical and/or angiographic results were used as gold standard. The effective radiation doses in 80 kV group (A group) and the 70 kV group (B+C group) were (0.49 ± 0.04) and (0.30 ± 0.03) mSv, respectively, with a statistically significant difference (t=4.037, P=0.001). Conclusions DSCTCA can better display and diagnose pediatric coronary artery lesions with 70 kV tube voltage combined with low contrast agent, and has a high diagnostic accuracy. It is a reliable method for diagnosing pediatric coronary artery disease.

Avaliação da relação entre o polimorfismo C677T no gene para MTHFR e a concentração plasmática de homocisteína na doença arterial coronariana / Evaluation of MTHFR C677T gene polymorphism and homocysteine level in coronary atherosclerotic disease / Evaluation of MTHFR C677T gene polymorphism and homocysteine level in coronary atherosclerotic disease

OBJETIVO: O objetivo deste trabalho é determinar a prevalência do polimorfismo C677T do gene metilenotetraidrofolato redutase (MTHFR) e associá-la com a concentração plasmática de homocisteína plasmática na doença arterial coronariana (DAC). MÉTODOS: Foram avaliados 93 pacientes com DAC documentada, atendidos no Hospital Universitário Oswaldo Cruz (Recife, PE, Brasil), e 108 controles sem a doença. Foram determinados os perfis lipídicos de pacientes e controles. As concentrações plasmáticas de homocisteína e folato foram determinadas por HPLC e quimioluminescência, respectivamente. A genotipagem foi realizada por RFLP/PCR. RESULTADOS: Os grupos de pacientes e controles foram homogêneos quanto aos perfis genéticos do polimorfismo investigado. Nos pacientes, as concentrações plasmáticas médias de homocisteina (11,7 ± 4,4 æmol/L) e de folato (6,22 ± 3,0 ng/dL) foram estatisticamente diferentes daquelas observadas nos controles (8,84 ± 3,2 æmol/L e 7,69 ± 3,1 ng/dL, respectivamente), ao nível de significância de 0,05. Entretanto, não houve correlação entre concentração plasmática de homocisteína e folato nos pacientes (r= -0,202). Não foi observada associação entre a homozigosidade 677TT para MTHFR e a concentração plasmática de homocisteína sérica (p= 0,634). A comparação dos casos e controles que apresentaram simultaneamente alta concentração plasmática de homocisteína e baixa concentração de folato, resultou numa razão de chance superior à de cada variável analisada independentemente (RC= 11,9; IC 95 por cento= 4,16-34,42, p< 0,01). CONCLUSÕES: A mutação C677T não parece ser um fator genético importante capaz de explicar a hiperhomocisteinemia moderada observada nos pacientes com DAC. Outros fatores, ambientais e genéticos, devem ser investigados.

OBJECTIVE: The aim of this study is to determine the prevalence of C677T methylenetetrahydrofolate reductase (MTHFR) polymorphism and correlate it with plasma homocysteine levels in coronary artery disease (CAD). METHODS: Ninety-three patients with documented CAD from Hospital Universitário Oswaldo Cruz (Recife, PE, Brazil) and 108 healthy controls were evaluated. Homocysteine and folate levels were determined by HPLC and chemoluminescence, respectively, and lipid profile was considered. Genotyping was done by RFLP/PCR. RESULTS: The groups were homogeneous for the C677T polymorphisms. The homocysteine level in cases (11.7 æmol/L) was statistically different from that observed in controls (8.84 æmol/L, p< 0.05). It was also observed that 72 percent of the patients had homocysteine values above12 æmol/L while the control group presented only 32 percent in this range. There was no relationship between homozigosity for the C677T polymorphism and the homocysteine level (p= 0.634). We noticed statistical differences between folate levels from patients and controls (6.22 and 7.69 ng/dL, p< 0.05, respectively). However, there was no correlation between homocysteine and folate concentrations in the entire group (r= -0.202). Comparing cases and controls, the odds ratio (OR) when homocysteine is high and folate is low was OR= 11.9; CI 95 percent= 4.16-34.42, p< 0.01. CONCLUSION: A lack of correlation between C677T mutation and homocysteine level suggests that environmental factors and others genetic factors seem to exert more influence on homocysteine level in this population.

Clinical Outcomes Following Sirolimus-Eluting Stent Implantation in Patients with End-Stage Renal Disease: Korean Multicenter Angioplasty Team (KOMATE) Registry

BACKGROUND AND OBJECTIVES: Sirolimus-eluting stents (SES), as opposed to bare metal stents (BMS), have been shown to markedly reduce restenosis. However, many clinical trials have excluded the subset of patients (pts) with end-stage renal disease (ESRD). The aim of this study was to evaluate the clinical outcomes following SES implantation in ESRD pts. SUBJECTS AND METHODS: We analyzed the clinical outcomes in 50 pts from our registry following SES implantation, and compared the outcomes between those with ESRD receiving SES (SES-ESRD) and BMS (BMS-ESRD), and with non-ESRD pts following SES implantation (SES-non ESRD). RESULTS: A comparison of the SES-ESRD (50 pts, 72 lesions) with BMS-ESRD groups (42 pts, 45 lesions); those in the SES-ESRD group included; diabetes 78%, hypertension 94% and age 62+/-10 years. Those in the SES-ESRD group were more likely to have diabetes (diabetes of BMS-ESRD, 57%; p=0.04). The reference vessel diameters (RVD) of the SES-ESRD group were smaller (2.76+/-0.50 mm vs. 3.05+/-0.46 mm, p<0.001), but the lesion length was longer (25.6+/-7.0 mm vs. 19.1+/-8.8 mm, p<0.001) than those of the BMS-ESRD group. The SES-ESRD group had a lower 1-year major adverse cardiac events (MACE) rate than the BMS-ESRD group (6.0% vs. 33.3%; p<0.001). There were no differences in mortality and incidence of myocardial infarction between the two groups. The incidence of target vessel revascularization decreased significantly in the SES-ESRD group (2.0% vs. 19.0%, p=0.01). From a multivariate regression analysis, the use of SES was the only significant independent predictor of MACE (OR=0.054, 95% confidence interval 0.01 to 0.26, p<0.001). A comparison with SES-non ESRD group in our total registry (644 pts, 758 lesions); MACE in the SES-ESRD group (6.0%) was higher than in the SES-non ESRD group (3.1%), but there was no statistical significance (p=0.23). CONCLUSION: Compared with BMS, SES caused an improvement in the clinical outcomes in pts with ESRD.

Morbidity and Mortality Analysis after Noncardiac Surgery in Patients with Prior Myocardial Infarction / 대한마취과학회지

BACKGROUND: Patients with a prior myocardial infarction who undergo noncardiac surgery have a higher risk of perioperative morbidity and mortality. Therefore, this study was designed to assess the outcomes after non-cardiac surgery in patients who had a previous myocardial infarction. METHODS: Ninety three patients who had a prior myocardial infarction and underwent noncardiac surgery were included in this study. The patients were divided as follows: the Complication group versus the Non-Complication group. A retrospective analysis was performed to determine if age, gender, ejection fraction, prior coronary revascularization, ASA physical status, operation time and type, perioperative vital signs, cardiac risk factor, preoperative medications and coronary multivessel disease influence the perioperative morbidity and mortality. RESULTS: Fourteen of the 93 patients (15.1%) had perioperative complications, of which 3 (3.2%) were fatal. All fatal patients had undergone noncardiac surgery within 3 months after the previous coronary revascularization. The incidence of intraoperative tachycardia and oliguria, operation time and the ASA physical status were longer and greater in the Complication group (P<0.05). Otherwise there were no significant differences between the two groups. CONCLUSIONS: The incidence of intraoperative tachycardia and oliguria, the operation time and ASA physical status influence the outcomes after noncardiac surgery of patients with a prior myocardial infarction. In addition, the interval between the coronary revascularization procedure and the noncardiac surgery has a major impact on postoperative mortality. However, prospective multi-center studies will be needed to determine the effects of several variables.

An effect comparison of perioperative intravenous Metoprolol bolus in 87 cases and intravenous calcium iron antagonist injection in 48 cases with noncardiac Surgery / 介入放射学杂志

Objection To compare the efficacy and tolerance of perioperative intravenous Metoprolol or calcium iron antagonist injection on patients with cardiac complications which undergoing noncardiac surgery. Method The clinical data of 135 patients who underwent noncardiac surgery from March 2003 to May 2004 was analyzed. According to the different drugs used to treat the perioperative cardiac complications (tachycardia arrhythmia, hypertension and myocardium ischemia), patients were allocated to metoprolol group (87 cases) and calcium antagonist group (48 cases, including Verapamil 21 patients and Diltiazem 27 patients). The effects of the therapy on heart rate and blood ressure control and ischemia relieving were compared between two groups. Results There is no significant difference at baseline data between two groups. Compared with calcium antagonist, intravenous metoprolol could more reduce heart and relieve myocardium ischemia quickly. The effect of blood pressure controlling was more significant in calcium antagonist group than in metoprolol group. The incidence of side-effects events was lower in metoprolol ( 8.0%) than in calcium antagonist group (22.9%).Conclusions Intravenous metoprolol injection is effective and safe in treating perioperative cardiac complications in patients with noncardias surgery.

The results have shown that the disease occurred mainly in patients with ages of 60-69; men with disease (64.6%); hypertension in grade I, II and III (60.3%) hyper cholesterolemia (56.3%); hypertriglyceridemia (25%), less physical exercise (58.7%); obesity in grade I, II, III (39%); diabetes (18.9%), left ventricular thickness (18.9%); postmentruation (85.3%). The study concluded that It is necessary to intervent early the risk factors to slow the progress of disease and reduce the accidents

Evaluation of quantitative analysis of troponin T enzyme in the diagnosis of coronary diseases

An evaluation of the quantitative analysis of troponin T (a new marker of coronary disease) was carried out in the 150 patients of cardiovascular department of Hautepierre Hospital, Strasbourg Medical University, France from January to August 1998. The results have shown that the value of troponin T was much higher than this of creatinine Kinase (CK) and CK- MB in the diagnosis of acute myocardial infarction. The possitive predict value was 90% and the negative predicts value was less than 50%.

Significance of Serum Troponin-T Level in Acute Ischemic Pain Syndrome / 대한내과학회지

OBJECTIVES: In coronary arterial disease, quantitative assessment of the extent of myocardial damage is important both in management of the patient and prediction of prognosis. Measurement of serum Troponin-T is a new method for detecting myocardial cellular injury, used as more specific marker of tissue damage and reperfusion status in acute myocardial infarction, This study was performed to evaluate the significance of serum Troponin-T measurement in various acute chest pain syndrome. METHODS: 37 patients who presented anterior ischemic chest pain enrolled from April, 1994 to September, 1995, From the initial period of admission, serial measurements of serum level of cardiac enzymes (CK, CK MB, Myoglobin, Troponin-T) were made. Then release time, peak time and normalization time of each enzyme were derived and compared each other. To evaluate whether Troponin-T level can reflect the extent of ischemic injury, correlation between peak Troponin-T level and peak CK MB level was analysed by regression method. RESULTS: 1) Acute myocardial infarction was confirmed in 15 cases; Q-wave myocardial infarction was 10 cases(anterior wall-5 cases, inferior wall-4 cases, lateral wall-1 cases), and non Q-wave myocardial infarction was 5 cases. Unstable angina was 22 cases. All cases had significant stenosis in coronary angiography. 2) The appearance in the serum level of 4 cardiac enzymes was as follows. The release time(hours) of 4 cardiac enzymes(Troponin-T, CK, CK MB, Myoglobin) were 7.1(1-30), 9.3(1-30), 9.9(1-30), 6.2(1-30). The peak time(hours) of 4 cardiac enzymes were 23.0(1.5-96), 21.6(2-66), 16.9(2-42), 12.7(3-40). The normalization time(hours) of the enzymes were over 72, 53.7(11-86), 52.3(11-94), 32.3(10-82). 3) Elevation pattern of cardiac enzymes showed concordance of all 3 enzymes(Troponin-T, CK MB, Myoglobin) in 29 of 43 cases(67.4%), There was concordance of 2 enzymes in 10 cases; 5 cases of CK MB and Myoglobin, 5 cases of Troponin-T and Myoglobin. In 4 cases, only Myoglobin level was increased. 4) There was significant correlation between peak Troponin-T level and peak CK level(r=0.66, p=0.0178), significant correlation was also observed between peak Troponin-T level and peak CK MR level(r=0.90, p=0.0001). CONCLUSION: In acute myocardial infarction serum Troponin-T was detectable as early as CK MB, and lasted longer after other enzyme level was normalized. There was significant correlation between peak Troponin-T level and peak CK, CK MB level, suggesting Troponin-T as useful marker for assessing the extent of myocardial damage.
