Underlying Processes

The two strands of treatment available for coronary artery disease and associated pathologies are pharmaceutical and physical. However, these treatments are typically only available too late to help tackle the early underlying processes. Better understanding of the underlying processes is key to the development of preventative solutions. One of the key processes understanding coronary problems is atherosclerosis, which is when arteries lose elasticity. Associate Professor Seisuke Mimori, Department of Clinical Medicine, Chiba Institute of Science, Japan, is examining the underlying biochemistry of atherosclerosis. Professor Tetsuto Kanzaki has succeeded in cloning a protein called LTBP-1 and, under his direction, Seisuke has created a mutant of the protein and is analysing it. He intends to produce variants of LTBP-1 in order to investigate the function of various domains of the protein. This will involve firstly producing and isolating the protein and its variants in sufficient quantities. Then, he will test cell migration rates through an assay that he and the team have designed. This will enable the researchers to clarify exactly how LTBP-1 functions. In the future, Seisuke and the team will investigate the exact mechanism of action of the domains involved and explore the impact of LTBP-1 on the relevant organs and cells.

Abstract Funding Acknowledgements Type of funding sources: Private company. Main funding source(s): Siemens Healthineers Introduction Coronary CT angiography (CCTA) plays an increasing role in the detection and risk stratification of patients with coronary artery disease (CAD). The Coronary Artery Disease – Reporting and Data System (CAD-RADS) allows for standardized classification of CCTA results and, thus, may improve patient management. Purpose Aim of this study was to assess the impact of CCTA in combination with CAD-RADS on patient management and to identify the impact of cardiovascular risk factors (CVRF) on CAD severity. Methods CCTA was performed on a third-generation dual-source CT scanner in patients, who were referred to a radiology centre by their attending physicians. In a total of 4801 patients, CVRF were derived from medical reports and anamnesis. Results The study population consisted of 4770 patients (62.0 (54.0-69.0) years, 2841 males) with CAD (CAD-RADS 1-5), while 31 patients showed no CAD and were excluded from further analyses. Age, male gender and the number of CVRF were associated with more severe CAD stages (all p < 0.001). 3040 patients (63.7 %) showed minimal or mild CAD requiring optimization of CVRF i.e. medical therapy but no further assessment at his time. A group of 266 patients (5.6 %) had a severe CAD defined as CAD-RADS 4B/5. In the multivariate regression analysis, age, male gender, history of smoking, diabetes mellitus and hyperlipidaemia were significant predictors for severe CAD, whereas arterial hypertension and family history of CAD did not reach significance. Of note, a subgroup of 28 patients (10.5 %) with a severe CAD (68.5 (65.5-70.0) years, 26 males, both p = n.s.) had no CVRF. Conclusions CCTA in combination with the CAD-RADS allowed for effective risk stratification of CAD patients. The majority of the patients showed non-obstructive CAD and, thus, could be treated conservatively without the need for further CAD assessment. CVRF out of arterial hypertension and family history had an impact on CAD severity reflected in higher CAD-RADs gradings. Of note, a relevant fraction of patients with CAD did not have any CVRF and, thus, may not be covered by risk stratification models.

Abstract Aims To investigate the impact of established cardiovascular disease (CVD) on 10-year all-cause death following coronary revascularization in patients with complex coronary artery disease (CAD). Methods The SYNTAXES study assessed vital status out to 10 years of patients with complex CAD enrolled in the SYNTAX trial. The relative efficacy of PCI versus CABG in terms of 10-year all-cause death was assessed according to co-existing CVD. Results Established CVD status was recorded in 1771 (98.3%) patients, of whom 827 (46.7%) had established CVD. Compared to those without CVD, patients with CVD had a significantly higher risk of 10-year all-cause death (31.4% vs. 21.7%; adjusted HR: 1.40; 95% CI 1.08–1.80, p = 0.010). In patients with CVD, PCI had a non-significant numerically higher risk of 10-year all-cause death compared with CABG (35.9% vs. 27.2%; adjusted HR: 1.14; 95% CI 0.83–1.58, p = 0.412). The relative treatment effects of PCI versus CABG on 10-year all-cause death in patients with complex CAD were similar irrespective of the presence of CVD (p-interaction = 0.986). Only those patients with CVD in ≥ 2 territories had a higher risk of 10-year all-cause death (adjusted HR: 2.99, 95% CI 2.11–4.23, p < 0.001) compared to those without CVD. Conclusions The presence of CVD involving more than one territory was associated with a significantly increased risk of 10-year all-cause death, which was non-significantly higher in complex CAD patients treated with PCI compared with CABG. Acceptable long-term outcomes were observed, suggesting that patients with established CVD should not be precluded from undergoing invasive angiography or revascularization.

The Impact

The most relevant comorbidities in patients with peripheral artery disease (PAD) are coronary artery disease (CAD) and diabetes mellitus (DM). However, data of long-term follow-up of patients with chronic total occlusion (CTO) are scarce. The aim of the study was to assess the impact of CAD and DM on long-term follow-up patients after superficial femoral artery (SFA) CTO retrograde recanalization. In this study, eighty-six patients with PAD with diagnosed CTO in the femoropopliteal region and at least one unsuccessful attempt of antegrade recanalization were enrolled in 2 clinical centers. Mean time of follow-up in all patients was 47.5 months (±40 months). Patients were divided into two groups depending on the presence of CAD (CAD group: n=45 vs. non-CAD group: n=41) and DM (DM group: n=50 vs. non-DM group: n=36). In long-term follow-up, major adverse peripheral events (MAPE) occurred in 66.6% of patients with CAD vs. 36.5% of patients without CAD and in 50% of patients with DM vs. 55% of non-DM subjects. There were no statistical differences in peripheral endpoints in both groups. However, there was a statistically significant difference in all-cause mortality: in the DM group, there were 6 deaths (12%) (P value = 0.038). To conclude, patients after retrograde recanalization, with coexisting CTO and DM, are at higher risk of death in long-term follow-up.

The Impact

Background: The objectives of the study were to identify the causes of premature ovarian insufficiency (POI) and to assess the severity of menopausal symptoms as well as the impact on cardiovascular health in these patients.Methods: Authors did a cross sectional case control study with 100 cases and 100 age matched controls. Women <40years of age with amenorrhoea >4months and FSH >25mIU/ml were identified with POI. Women <40years with normal cycles were the controls. Causes were identified from medical records and menopausal symptoms were categorized using menopause rating score questionnaire. Hypercholesterolemia (≥200mg/dl), hypoalbuminemia (<3.5g/dl) and high sensitive C reactive protein (HS-CRP ≥3mg/dl) were assessed as the early markers of coronary artery disease. Statistical methods included Chi square test and logistic regression analysis. P value <0.05 was considered significant.Results: 64% of the patients were between 31-40 years. 66% of them were into menopause for <5 years. The cause was idiopathic in 62%. 91% had no or minimal menopausal symptoms. Hypoalbuminemia (6 versus 1, 95% CI 1.8-2.4, OR 2.1, p=0.01) and hypercholesterolemia (75 versus 51, 95%CI 2.5-3.1, OR 2.8, p= 0.001) were significantly high in cases. HS-CRP was not found to be different between the groups (59 versus 49, OR 1.5, 95%CI 0.8-2.6, p=0.2).Conclusions: In majority with POI the cause is idiopathic and menopausal symptoms are minimal. Hypoalbuminemia and hypercholesterolemia, markers of coronary artery disease, were significantly elevated in POI. Early screening for these variables within 5 years of menopause would reduce the cardiovascular mortality in these patients.

Background: Postmenopausal women experience rapid progression of coronary artery disease. Vitamin D deficiency appears to be a modifiable risk factor for cardiovascular diseases. This study aimed to analyze the impact of 25-hydroxyvitamin D3 (25(OH)D) level on the severity of coronary atherosclerosis and its potential cardioprotective effect in postmenopausal women. Material and Methods: The study prospectively recruited 351 women in postmenopausal age undergoing coronary angiography. The severity of coronary atherosclerosis was assessed using the Coronary Artery Surgery Study Score (CASSS). A level of 25(OH)D was measured with electrochemiluminescence. Results: Women with more severe coronary atherosclerosis have significantly lower 25(OH)D serum level (p = 0.0001). Vitamin D (β = −0.02; p = 0.016), hypertension (β = 0.44; p = 0.025), age (β = 0.02; p = 0.003), and history of MI (β = 0.63; p < 0.0001), were shown as CASSS determinants. Age, hyperlipidemia, and history of MI were found to determine the level of vitamin D (all p < 0.05). Women with a three-vessel disease hospitalized due to ACS, with a history of MI, hyperlipidemia and hypertension presented the lowest vitamin D level. Conclusions: Our study showed that lower serum 25(OH)D in postmenopausal women is associated with more significant stenosis in the coronary arteries. Therefore, we suggest considering low vitamin D level as a potential risk factor for coronary artery disease.
