Background and Aims. Lipid metabolism plays important roles in atherosclerosis. Several studies have found that lipoprotein is associated with coronary artery disease (CAD) and hyperlipidemia. Although the roles of the apolipoprotein B/A1 ratio (ApoB/A1) were originally thought to be atherosclerotic, few studies have focused on the specific relationship between ApoB/A1 and severity of coronary artery stenosis with or without the presence of CAD. Methods. A total of 6956 consecutive patients aged 21–98 years with suspected CAD who had undergone coronary angiography were enrolled. The severity of coronary lesions was evaluated using the Gensini score (GS). The relationships between ApoB/A1 and severity of coronary artery stenosis were evaluated. Results. A total of 1795 non-CAD patients and 5161 CAD patients were included in the observational analysis. Patients with CAD had higher ApoB/A1 than individuals without CAD (0.67 (0.53-0.82) vs. 0.61 (0.49-0.75), p < 0.001 ). In CAD patients, the higher the ApoB/A1 was, the higher the proportion of patients with MI, triple-vessel lesions, and higher Gensini scores. ApoB/A1 was significantly positively correlated with HbA1c and Gensini scores in CAD patients but not in non-CAD patients (all p < 0.001 ). Logistic analyses showed that ApoB/A1 could be a risk factor for multivessel disease (OR: 2.768, 95% CI: 1.868-4.103, p < 0.001 ). ApoB/A1 was found to be significantly positively correlated with the Gensini score in CAD patients. Conclusions. ApoB/A1 is highly associated with the presence and severity of coronary artery stenosis in patients with CAD but not in non-CAD patients.

Abstract Human non-mercaptalbumin (HNA), oxidized form of serum albumin, has been reported as a useful marker in oxidative stress-related diseases; however, few reports have examined the association between HNA and the severity of coronary artery disease (CAD). The present study evaluated whether the HNA fraction is correlated with coronary artery stenosis in 140 patients considered to have a high risk of CAD or who were suspected of having acute coronary syndrome. The severity of CAD was defined by the number of stenotic coronary vessels and a severity score system (the Gensini score). HNA measurements were performed using our newly established high-performance liquid chromatography methodology. The results had shown that HNA was significantly increased in patients with three-vessel disease, compared with those without CAD or with single-vessel disease (p=0.025), and was positively correlated with the Gensini score (ρ=0.421, p<0.001). A multivariate analysis showed that the number of stenotic vessels was an independent and significant factor associated with HNA (ρ=1.246, p=0.012). A logistic regression analysis showed that HNA was a strong predictor of multivessel CAD (odds ratio, 1.12; 95% confidence interval, 1.020-1.229; p=0.017). These findings indicate that the measurement of HNA could be clinically practical for predicting the severity of coronary artery stenosis.

Background: Now a days coronary artery disease (CAD) becomes major cause of death. One among 7 deaths in America caused by CAD. CAD is an atherosclerosis process, which progresively develops into plaque that will lead to stenosis of coronary artery lumen. Several studies found that high serum fibrinogen level is an independent and significant to the severity of artery coronary stenosis. Serum fibrinogen level determined by genetic factor. Polymorphism of fibrinogen gene β -455 G/A seem plays an important role in plasma fibrinogen level. Although some studies showed a significant correlation between polymorphism and cardiovascular diseases, but some other studies report inversely. Aim. To evaluate the correlation between the polymorphism of fibrinogen gene β -455 G/A and serum fibrinogen level with the severity of artery coronary stenosis. Method: This is an analytic correlative study with prospective approach without comparison. Coronary angiography was performed in catheterization labor in the department of internal medicine, while DNA analysis and PCR done in the department of microbiology in General Hospital dr Muhammad Husin Palembang- Indonesioa, since July 2015 until Agustus 2016. Samples are CAD patient who undergo for coronary angiography and fulfield the criterias. The severity of stenosis in coronary artery determined by Gensini score. This study included 31 patient. Results. Among 31 CAD patients, this study found severe stenosis of coronary artery in 17 patients (53,1%), moderate in 5 patients (15,6%) and mild in 10 patients (31,2%). Genetic analysis showed that serum fibrinogen level was controlled by polymorphism of fibrinogen gene β -455 G/A, concecutively by genotipe AA in 15 patients (48,4%), genotipe GA in 12 patient (38,7%) and by genotipe GG in 4 patients (12,9%). Chi Square test showed a significant correlation between polymorphism gene fibrinogen β -455 G/A and serum fibrinogen level (p=0,039). Spearman’s rho test found no significant correlation between serum fibrinogen level and severity of coronary artery stenosis based on Gensini score (r=0,142; p=0,447). And also this study found no significant correlation between polymorphism gene fibrinogen β -455 G/A with the severity of stenosis in coronary artery (p=0,512). Conclusion. Although this study succeded to prove that serum fibrinogen level was determined by polymorphism fibrinogen gene β -455 G/A, but there are no significant correlations between polymorphism fibrinogen gene β -455 G/A and serum fibrinogen level with severity of coronary artery stenosis in CAD patients. This study suggest to study other candidate gene to look for other cardiac risk beside this fibrinogen. Bangladesh Journal of Medical Science Vol.18(2) 2019 p.379-384

Endothelial dysfunction is an important step in the atherosclerosis progression, and associates with future cardiovascular events. Reactive hyperemia peripheral arterial tonometry (RH-PAT) is a noninvasive, automatic, and objective tool to evaluate endothelial dysfunction. Angiographic complex coronary lesions are involved in plaque vulnerability. We investigated whether finger values of RH-PAT could correlate with angiographic coronary plaque complexity in patients with coronary artery disease (CAD). RH-PAT was measured using Endo-PAT2000 in 171 patients who were referred to Kumamoto University Hospital for cardiac catheterization. We defined the two group as below, Control group; coronary artery stenosis > 25% (n = 36, age 63 ± 11, male 25 %), and CAD group; coronary artery stenosis > 25 % (n = 135, age 68 ± 11, male 74 %). Coronary lesions (single-vessel; n = 29, multi-vessel disease; n = 106) were classified as of simple appearance (n = 43) or complex appearance (n = 92) by coronary angiography. Values of RH-PAT were significantly lower in patients with CAD than Control (1.65 [1.50 – 1.86] versus 1.92 [1.80 – 2.28], P < 0.01), and were significantly lower in CAD patients with complex coronary appearance than patients with simple coronary appearance (1.55 [1.45 – 1.76] versus 1.81 [1.66 – 1.95], P < 0.01). All patients underwent selective coronary angiography, and the extent of coronary stenosis was assessed using the scoring system. RH-PAT was significantly correlated with coronary plaque Extent Score (Rs = −0.33, P < 0.01). Single logistic regression analysis demonstrated that high-density lipoprotein cholesterol, triglycerides, and RH-PAT value significantly associated with the presence of complex coronary lesions, and multivariable analysis including cardiovascular risk factors identified that lower RH-PAT value was the only factor associated with the complex coronary lesions (odds ratio 1.45, 95% confidence interval 1.14 – 1.84; P < 0.01). Endothelial dysfunction was significantly associated with angiographic complex appearance of coronary plaques in patients with CAD. CAD patients with lower RH-PAT values might be vulnerable patients with vulnerable plaques and vulnerable endothelium.

: Percutaneous Coronary Intervention (PCI) has revolutionized the management of Coronary Artery Disease and has become the preferred modality of revascularization in a majority of cases. Nevertheless, situations are encountered frequently where device deliverability to coronary lesions entails technical difficulties due to varied anatomies and lesional complexities like tortuosity, calcifications, length of lesions and vessel morphology. While continuous technological refinements are occurring in PCI hardware armamentarium and stent designs, a number of techniques and their modifications and variations have evolved to increase the applicability of PCI to difficult lesions. : The present article envisages a thorough review of all aspects of improving successful device deliverability in complex PCI with prominent emphasis on increasing the backup support of Guide Catheters which is the primary factor of success in difficult coronary lesions.

Гены тромбообразования и фолатного обмена играют важную роль в развитии и прогрессии ишемической болезни сердца (ИБС). Однако о возможной роли полиморфных маркеров в рецидиве ИБС после чрескожного коронарного вмешательства (ЧКВ) известно недостаточно. Цель исследования: Оценить роль генетических факторов системы тромбообразования и фолатного обмена (полиморфных маркеров генов F5, F2, F13A1, PAI1, HPA1, MTHFR, FGB ), в возобновление клиники ИБС после ЧКВ. Методика: Исследование проводили с использованием выборки из 90 больных ИБС в возрасте от 40 до 75 лет: 75 пациентов после планового ЧКВ (60 мужчин и 15 женщин) и 15 лиц после экстренного ЧКВ (12 мужчин и 3 женщины). Молекулярно-генетическое исследование было выполнено с помощью комплекта реагентов «Сердечно-сосудистые заболевания СтрипМетод»® (ViennaLab Diagnostics GmbH, Австрия), выявляющие следующие варианты: F5, F2, F13A1, PAI1, HPA1, MTHFR, FGB . Результаты: В результате исследования была показана ассоциация полиморфного маркера G103T ( Val34Leu ) гена F13A1 (фактор свертываемости крови 13, субъединица A1) с развитием рецидивирующего состояния ИБС после ЧКВ. Выявлены статистически значимые различия в распределении частот генотипов полиморфного маркера Val34Leu гена F13A1 . Показано, что частота генотипа Val/Val у пациентов с осложнениями была выше, чем у пациентов без таковых: 0,700 и 0,400 соответственно (c = 7,78; p = 0,020), при этом генотип Val/Val проявил себя как фактор риска развития осложнений: ОШ = 3,50 (95%ДИ 1,37-8,93). При сравнении аллелей выявили, что частота аллеля L у больных с осложнениями была ниже, чем у лиц без таковых: 0,167 и 0,375 соответственно (p = 0,004), и носительство аллеля L уменьшало вероятность развития осложнений: ОШ = 0,33 (95%ДИ 0,15-0,72). Заключение: Носительство варианта 34V гена F13A1 , кодирующего A-субъединицу фактора свёртывания 13, предрасполагает к возобновлению клинических проявлений ИБС после ЧКВ. Genes of thrombosis and folate metabolism play an important role in development and progression of coronary artery disease (CAD). However, a possible role of polymorphic markers in CAD relapse following percutaneous coronary intervention (PCI) is not sufficiently understood. Background. Reports have indicated an association of genetic factors generally related with thrombophilia and recurrence of symptoms for coronary artery disease (CAD) following a percutaneous coronary intervention (PCI) due to restenosis and in-stent thrombosis. However, the relapse can also be caused by progression of atherosclerosis and endothelial dysfunction in unoperated blood vessels. Aim: To assess the role of genetic risk factors involved in thrombosis and folate metabolism (polymorphic markers of F5, F2, F13A1, PAI1, HPA1, MTHFR, and FGB genes) in recurrence of CAD symptoms after PCI. Methods: The study included 90 patients with CAD aged 40-75; 75 of these patients had undergone elective PCI (60 men and 15 women) and 15 patients - emergency PCI (12 men and 3 women). Molecular genetic tests were performed using a CVD StripAssays® reagent kit (ViennaLab Diagnostics GmbH, Austria) to identify the following genetic variations: F5, F2, F13A1, PAI1, HPA1, MTHFR, and FGB . Results: The study results showed a significant association of the G103T ( Val34Leu ) polymorphism in the F13A1 gene with relapses of IHD after PCI. Significant differences were found in genotype distribution frequencies of the Val34Leu polymorphism in the F13A1 gene. The frequency of Val / Val genotype was higher in patients with complications than without complications, 0.700 and 0.400, respectively (c = 7.78, p = 0.020). Furthermore, the Val/Val genotype can be classified as a risk factor for complications (OR = 3.50; 95% CI, 1.37-8.93). The L allele frequency was lower in patients with complications than in those without complications (0.167 and 0.375, respectively, p = 0.004), and carriage of the L allele reduced the likelihood of complications (OR = 0.33; 95% CI 0.15-0.72). Conclusion: Carriage of the 34V variant in the F13A1 gene that encodes the coagulation factor XIII A subunit predisposes to a relapse of CAD symptoms after PCI.
