Background:The effects of eicosapentaenoic acid (EPA) on coronary artery disease have been previously reported; however, those of the addition of EPA to strong statins on coronary plaque components and local inflammatory cytokines are not known.Methods and Results:A total of 95 patients who had been treated with strong statin for at least 6 months were randomized into 2 groups: an EPA group (additional treatment with EPA at 1,800 mg/day, n=48) or a control group (no additional treatment, n=47), for 6 months. The tissue characteristics of target coronary plaque in each patient were analyzed using IB-IVUS before and after treatment. We also measured plasma levels of inflammatory cytokines sampled in the coronary sinus (CS) and peripheral vein.A significant reduction in lipid volume (18.5±1.3 to 15.0±1.5 mm3, P=0.007) and a significant increase in fibrous volume (22.9±0.8 to 25.6±1.1 mm3, P=0.01) were observed in IB-IVUS image analyses in the EPA group, but no significant changes in the plaque components in the control group. CS levels of pentraxin 3 and monocyte chemoattractant protein-1 were lower after than before treatment with EPA (3.3±2.1 to 2.6±1.2 ng/ml, 120.4±26.2 to 110.2±26.8 pg/ml, P=0.015 and P=0.008, respectively); however, there were no significant changes in those inflammatory cytokines between pre- and post-treatment in the control group.Conclusions:The addition of EPA was associated with reduced lipid volume in coronary plaques and decreased inflammatory cytokines.

Background:The coronary adventitia has recently attracted attention as a source of inflammation because it harbors nutrient blood vessels, termed the vasa vasorum (VV). This study assessed the link between local inflammation in adjacent epicardial adipose tissue (EAT) and coronary arterial atherosclerosis in fresh cadavers.Methods and Results:Lesion characteristics in the left anterior descending coronary artery of 10 fresh cadaveric hearts were evaluated using integrated backscatter intravascular ultrasound (IB-IVUS), and the density of the VV and levels of inflammatory molecules from the adjacent EAT were measured for each of the assessed lesions. The lesions were divided into lipid-rich, lipid-moderate, and lipid-poor groups according to percentage lipid volume assessed by IB-IVUS. Higher expression of inflammatory molecules (i.e., vascular endothelial growth factor A [VEGFA] andVEGFB) was observed in adjacent EAT of lipid-rich (n=11) than in lipid-poor (n=11) lesions (7.99±3.37 vs. 0.45±0.85 arbitrary units [AU], respectively, forVEGFA; 0.27±0.15 vs. 0.11±0.07 AU, respectively, forVEGFB; P<0.05). The density of adventitial VV was greater in lipid-rich than lipid-poor lesions (1.50±0.58% vs. 0.88±0.23%; P<0.05).Conclusions:Lipid-rich coronary plaques are associated with adventitial VV and local inflammation in adjacent EAT in fresh cadavers. This study suggests that local inflammation of EAT is associated with coronary plaque progression via the VV.

Background:Whether preoperative echocardiography improves postoperative outcomes is not well established, so we examined the value of echocardiographic assessment on the onset of postoperative heart failure (HF), and determining which patients benefitted most from undergoing echocardiography prior to major elective non-cardiac surgery.Methods and Results:We identified all patients aged 50 years and older who had major elective non-cardiac surgery, and excluded patients with previously identified severe cardiovascular disease. The primary endpoint was the onset of HF during hospitalization. A total of 806 patients were included in the analysis. During hospitalization, 49 patients (6%) reached the primary endpoint. Within the matched cohort, preoperative echocardiography was associated with a statistically significant decrease in postoperative HF (hazard ratio: 0.46, P=0.01). In subgroup analyses, age, sex, body surface area, hypertension, diabetes mellitus, prior HF, surgical type, chronic kidney disease, pulmonary disease, and malignancy influenced the association of echocardiography with postoperative HF.Conclusions:The use of echocardiography in elderly patients with certain risk factors was associated with improved postoperative outcomes. The basis for this finding remains to be determined; particularly whether echocardiography is simply a marker of a population with better outcomes or whether it leads to better management that improves outcomes.

Urinary albumin excretion is a predictor of cardiovascular death. Cardiac rehabilitation (CR) with exercise training (ET) has been shown to improve exercise capacity and prognosis in patients with cardiovascular disease (CVD). However, it remains unclear whether CR reduces urinary albumin excretion in CVD patients. We performed a retrospective, observational study using data obtained from 98 male CVD patients without macroalbuminuria and estimated glomerular filtration rate (eGFR) < 30 mL/minute/1.73 m2 who participated in CR with ET during hospitalization. Twenty-three patients continued supervised ET for 6 months (supervised group) and 75 patients quit supervised ET (non-supervised group). The supervised ET program consisted of 60 minutes of supervised sessions 1-3 times a week and 30-60 minutes of home exercise at least twice a week. Urinary albumin/creatinine ratio (ACR) was significantly decreased in the supervised group at 6 months after enrollment (43 ± 71 mg/g to 17 ± 20 mg/g creatinine, P < 0.05) but not in the non-supervised group. eGFR was unchanged in the supervised group but was significantly decreased in the non-supervised group (72 ± 18 mL/minute/1.73 m2 to 67 ± 17 mL/minute/1.73 m2, P < 0.001). The results of multiple regression analysis showed that only supervised ET was an independent contributor to ΔACR. CR with supervised ET decreased urinary albumin excretion without deterioration of renal function. These findings suggest that continuation of a supervised ET program is associated with reduction in the development of CVD and reduction in cardiovascular morbidity and mortality in CVD patients.

Background:High prevalence of frailty and of diastolic dysfunction (DD) in heart failure and high mortality in frail adults have been noted. We characterized frailty by quantifying differences on echocardiography, and assessed the added prognostic utility of frailty and DD grade in an elderly population.Methods and Results:One hundred and ninety-one patients ≥65 years who had at least 1 cardiovascular risk factor were prospectively recruited for clinically indicated echocardiography at the present institute. Weight loss, exhaustion, and deficits in physical activity, gait speed, and handgrip strength were used to categorize patients as frail (≥3 features), intermediately frail (1 or 2 features), or non-frail (0 features). DD grade ≥2 was defined as severe. Frailty was associated with larger left atrial volume, smaller stroke volume, and worse DD grade after adjustment for age. In a period of 14 months, 29 patients (15%) had cardiovascular events. The addition of frailty score and severe DD significantly improved the prognostic power of a model containing male gender (model 1, male gender, χ2=6.4; model 2, model 1 plus frailty score, χ2=16.7, P=0.004; model 3, model 2 plus severe DD, χ2=25.5, P=0.015).Conclusions:Both frailty and DD grade were significantly associated with future cardiovascular events in an elderly population with preserved ejection fraction and ≥1 risk factor of cardiovascular disease.

Aim: The consumption of n-3 polyunsaturated fatty acids (PUFA), including docosahexaenoic acid DHA), reduces the incidence of cardiovascular events, and reduced serum levels of n-3 PUFA may be associated with an increased risk of cardiovascular events. However, controversy remains regarding which components of PUFA are associated with the endothelial function in patients with coronary artery disease (CAD). We therefore examined the associations between the n-3 and n-6 PUFA levels and CAD.Methods: We retrospectively reviewed 160 consecutive Japanese patients with CAD whose endothelial function was measured according to the percent change in flow-mediated dilation (FMD) and the serum levels of n-3 PUFA, including eicosapentaenoic acid (EPA) and DHA, and n-6 PUFA, including arachidonic acid (AA) and dihomo-gamma-linolenic acid (DHLA).Results: A single regression analysis showed no relationships between the FMD and the serum levels of PUFA, including EPA, DHA, AA and DHLA. In contrast, a multiple regression analysis showed that the DHA level was a positive (P<0.01) and age was a negative (P<0.001) contributor to an increased FMD; however, sex, body mass index, systolic and diastolic blood pressure, current/past smoking and the levels of HbA1c, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, EPA, AA and DHLA did not significantly affect the outcome.Conclusions: The serum level of DHA is associated with the endothelial function evaluated according to the FMD in patients with CAD, thus suggesting that a low serum level of DHA may be a predictive biomarker for endothelial dysfunction.
