Objective The aim of this study was to evaluate whether overweight and obesity are associated with arterial abnormalities in postmenopausal women and the contribution of the metabolic syndrome. Methods A total of 390 postmenopausal women (mean age, 63.1 ± 7.7 y) living in the metropolitan area of Naples, Southern Italy, and participating in a population-based cohort study (Progetto Atena) were offered an ultrasound examination of the carotid arteries; 370 women accepted. Blood pressure, serum high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, fasting glucose, insulin, apolipoprotein B, and high-sensitivity C-reactive protein were measured in all participants. Results Women in the second and third tertiles of body mass index showed a greater common carotid intima-media thickness compared with those in the first tertile (tertile II vs I, odds ratio, 2.15; P = 0.013; tertile III vs I, odds ratio, 2.24; P = 0.018), adjusted for age and metabolic syndrome. Obese and overweight postmenopausal women showed greater common carotid lumen diameters as compared with lean postmenopausal women (mean ± SD, 6.36 ± 0.86, 6.16 ± 0.65, and 5.96 ± 0.59 mm, respectively; P < 0.001 [obese vs lean] and P = 0.04 [overweight vs lean]); no statistical difference in carotid lumen diameter was found between obese and overweight postmenopausal women. The statistical significance between obese and lean postmenopausal women was retained even after adding the components of the metabolic syndrome as covariates. Conclusions These findings indicate an association between overweight, obesity, and preclinical carotid artery abnormalities, independently of the metabolic syndrome, in a population of postmenopausal women.

Background. Sirolimus-coated balloons (SCBs) represent a novel therapeutic option for both in-stent restenosis (ISR) and de novo coronary lesions treatment, especially in small vessels. Our registry sought to evaluate the procedural and clinical outcomes of such devices in a complex acute coronary syndrome (ACS) clinical setting. Methods and Results. We treated 74 consecutive patients with percutaneous coronary intervention (PCI) with at least 1 SCB used for ISR and/or de novo coronary lesion in small vessels at our institution. Sixty-two patients presented with ACS, and their data were included in our analysis. The mean age was 67 ± 10 years, and patients presenting with ST-elevated myocardial infarction (STEMI) were 14 (23%). De novo lesions were 52%, whereas ISR was 48%. Procedural success occurred in 100% of the cases. At the 11 ± 7 months follow-up, major adverse cardiovascular events (MACEs) were 3 (4.8%). Cardiovascular death (CD) occurred in 1 (1.6%) patient and myocardial infarction (MI) in 2 patients (3.2%) as well as ischemia-driven target lesion revascularization (TLR). One probable subacute thrombosis occurred (1.6%) with no major bleedings. In a subgroup analysis, the incidence of MACE did not show significant differences between patients treated for de novo lesions and ISR (HR: 0.239; CI 95%: 0.003–16.761, $p=0.509$ ). Conclusions. In the SELFIE prospective registry, SCB showed a good safety and efficacy profile for the treatment of coronary lesions, both ISR and/or de novo in small vessels, in a complex ACS population of patients at the 11 ± 7 months follow-up.

Objective: To assess the efficacy and safety of laser-assisted percutaneous coronary interventions (PCI) in an unselected population. Methods: One hundred consecutive patients, who underwent a laser assisted PCI between January 2008 and March 2012, were included in the present study. Fifty-one patients underwent laser ablation for thrombus vaporization (Group 1), 36 patients for neointima/plaque debulking (Group 2) and 13 patients for lesion compliance modification in calcified lesions (Group 3). Results: The rate of in-hospital serious events was 2%. The cumulative laser success was 82%, and it was significantly higher for Group 1 and Group 2 in comparison with Group 3 (p=0.001). Furthermore, the need for repeat revascularization was significantly higher in the Group 3 compared with the others two groups (46% vs. 8% for Group 1 and 11% for Group 2, p=0.03). The MACE rate was 14%. There was a trend toward a higher MACE rate in the Group 3 compared with others two groups (p=0.05). Conclusions: Laser ablation is an effective and safe tool for complex PCI. Patients underwent laser for thrombus vaporization or for neointima/plaque debulking had better immediate success and better outcome at follow-up than patients underwent laser for lesion compliance modification.

Objective Coronary blood flow exhibits a biphasic pattern at rest with a higher diastolic and a smaller systolic component. In the present investigation, we evaluated whether a decreased diastolic to systolic velocity ratio of basal coronary flow may be useful in the identification of subjects with significant left anterior descending coronary artery (LAD) stenosis. Methods One hundred and twenty-nine consecutive patients (62 with unstable angina, 25 with acute myocardial infarction and 42 with chronic coronary artery disease) were included in the study. Blood flow velocities were recorded in the mid-distal portion of the LAD using an ATL 5000 CV HDI ultrasound system. All patients underwent coronary angiography and were divided into two groups according to the absence (group 1) or the presence (group 2) of significant LAD stenosis (lumen narrowing ≥ 70%). In 60 of the 129 patients, coronary flow reserve was evaluated non-invasively. Results Adequate Doppler recordings in the LAD were obtained by transthoracic echocardiography in 113 patients. There were no differences between groups with regard to sex, cardiovascular risk factors, left ventricular mass and volumes, ejection fraction, whereas the diastolic to systolic velocity ratio of basal coronary flow was significantly lower in group 2 patients (1.41 ± 4.7 vs. 2.08 ± 0.64, P < 0.00001). The receiver operating characteristic curve showed that a diastolic to systolic velocity ratio < 1.6 had a sensitivity of 77%, a specificity of 91%, a positive predictive value of 77%, a negative predictive value of 97%, and a diagnostic accuracy of 84% for the presence of significant LAD stenosis. In 55/60 patients, results of basal coronary flow and coronary flow reserve were concordant. On multivariate logistic regression analysis, the diastolic to systolic velocity ratio was a strong independent predictor of LAD stenosis ≥ 70% (odds ratio 4.90, 95% confidence interval 1.65–7.30). Conclusions The present findings suggest that assessment of basal coronary flow in the LAD may be useful to rule out the presence of significant stenosis.
