ABSTRACT

AIMS: Depression and atherosclerotic cardiovascular disease (ASCVD) are commonly clustered in affected patients. Endothelial dysfunction is an early marker of ASCVD while also reported in patients with depression. Emerging evidence suggests that selective serotonin receptor inhibitors (SSRIs) may improve endothelial function. However, clinical studies assessing flow-mediated dilation (FMD), the gold-standard method to evaluate conduit artery endothelial function, in response to SSRIs treatment included limited number of patients and did not provide consistent results. In the present study we aim to evaluate the effect of SSRIs treatment on endothelial function assessed by longitudinal changes in FMD. METHODS AND RESULTS: We performed a systematic review to retrieve and subsequently meta-analyze eligible studies in patients with depression who received SSRIs and had available measurements of FMD change before and after treatment. In 5 studies and 323 individuals in total, SSRIs were associated with increased FMD at the end of follow-up compared to baseline measurement (pooled mean change 1.97 %, 95 % CI 0.17, 3.77, P = 0.032, I2 = 87.4 %). These results did not substantially change when analysis was restricted to patients with history of atherosclerotic cardiovascular disease (ASCVD). Similarly, FMD changes were higher in individuals receiving SSRIs compared to not-treated subjects (pooled mean difference 2.5 %. 95 % CI 0.7, 4.2, P < 0.001, I2 = 82.7 %). LIMITATIONS: Substantial heterogeneity regarding with respect to follow-up duration, demographics, and SSRIs agents. CONCLUSION: SSRIs significantly improve FMD, the gold-standard marker of endothelial function. Further investigation is warranted for the role of FMD as a possible therapeutic biomarker in patients with depression and established or subclinical ASCVD. PROSPERO REGISTRATION: CRD42021252241.

ABSTRACT

BACKGROUND: Remnant cholesterol (RC) is an emerging factor contributing to residual risk for the development of atherosclerotic cardiovascular disease (ASCVD). We aimed to investigate the association of RC with ASCVD in high ASCVD risk patients. METHODS: RC was calculated in 906 participants (178 low/moderate-risk and 728 high-risk) consecutively recruited from a vascular registry. Subclinical carotid atherosclerosis was assessed by B-mode carotid ultrasonography. Maximal carotid wall thickness (maxWT) and carotid atherosclerotic burden (n ≥ 2 atherosclerotic plaques) were set as the vascular outcomes. An independent cohort of 87 consecutively recruited high-risk patients who were followed for their lipid profile for 3 months was also analyzed. RESULTS: RC was increased in the high-risk group as compared to controls (26 ± 17 vs. 21 ± 11 mg/dl, respectively, p < 0.001). Increased RC levels were independently associated with increased maxWT and carotid atherosclerotic burden (p < 0.05), after adjustment for traditional cardiovascular risk factors (TRF) and ASCVD. RC levels were associated with the presence of flow-limiting ASCVD and coronary artery disease (CAD) (p < 0.05), after adjustment for TRFs. These associations remained significant in those not receiving hypolipidemic treatment and in treated individuals achieving LDL-C<100 mg/dl. In the prospective cohort, there was no significant interaction between change in RC levels and hypolipidemic status, as contrasted to LDL-C levels (p < 0.001). CONCLUSION: In a high-risk population, RC was associated with subclinical and clinically overt ASCVD, particularly in patients with the most adverse lipid phenotype (untreated) or in treated patients with a low LDL-related risk profile. These findings support a residual pro-atherosclerotic role of RC in high-risk patients.

ABSTRACT

Purpose: To investigate contemporary results of percutaneous transluminal renal angioplasty (PTRA).Materials and Methods: A multicentre retrospective study analysing all patients treated with PTRA for primary symptomatic renal artery stenosis (RAS) between 2010 and 2013 at four tertiary centres. Procedures during the preceding four years were counted to evaluate for change in PTRA frequency.Results: The number of PTRA procedures decreased by approximately 50% from 2006 to 2013. Patients treated in the post-ASTRAL period (n = 224) had a significant reduction in mean systolic pressure (168 to 146 mmHg, p < 0.01), diastolic pressure (84 to 76 mmHg, p < 0.01), number of anti-hypertensive drugs (3.54 to 3.05, p < 0.01), and anti-hypertensive treatment index (21.75 to 16.92, p < 0.01) compared to before PTRA. These improvements were maintained at one year and at the last clinical evaluation after a mean follow-up of 4.31 years. Renal function increased transiently without sustained improvement, or deterioration, during later follow-up. Thirteen patients (5.8%) eventually required dialysis, nine of these had eGFR <20 ml/min/1.73 m2 before PTRA. There was no difference in outcomes between subgroups differentiated by different indications for PTRA.Conclusion: The frequency of PTRA has decreased, indicating a higher threshold for invasive treatment of RAS in recent years. The reduction in blood pressures, the reduced need for anti-hypertensive medication, and stabilization of renal function over time suggest a clinical benefit for most patients who are now being treated with PTRA.

ABSTRACT

BACKGROUND: Arteriovenous fistulas and grafts are the methods of choice for vascular access in renal failure patients in need of hemodialysis. Their major complication, however, is stenosis, which might lead to thrombosis. PURPOSE: To demonstrate the usefulness of 16-MDCTA with 3D image reconstructions, in long-term hemodialysis patients with dysfunctional arteriovenous fistulas and grafts (AVF and AVG). MATERIAL AND METHODS: During a 17-month period, 31 patients with dysfunctional AVF and AVG (24 AVF and seven AVG) were examined with MDCTA with 3D image postprocessing. Parameters such as comprehension of the anatomy, quality of contrast enhancement, and pathological vascular changes were measured. DSA was then performed in 24 patients. RESULTS: MDCTA illustrated the anatomy of the AVF/AVG and the entire vascular tree to the heart, in a detailed and comprehensive manner in 93.5% of the evaluated segments, and depicted pathology of AVF/AVG or pathology of the associated vasculature. MDCTA demonstrated a total of 38 significant stenoses in 25 patients. DSA verified 37 stenoses in 24 patients and demonstrated two additional stenoses. MDCTA had thus a sensitivity of 95%. All 24 patients were treated with percutaneous transluminal angioplasty (PTA) with good technical results. CONCLUSION: MDCTA with 3D reconstructions of dysfunctioning AVFs and AVGs in hemodialysis patients is an accurate and reliable diagnostic method helping customize future intervention.

ABSTRACT

BACKGROUND: Cutaneous perforators that do not originate from the deep inferior epigastric artery (DIEA) are rare, but may significantly affect operative outcome. Peritoneal-cutaneous perforators have been described as a source for augmenting the blood flow to a deep inferior epigastric perforator (DIEP) flap, however if unrecognized, may compromise flap survival. METHODS: We reviewed 375 DIEA perforator (DIEP) flaps (325 with preoperative CTA and 50 cadaveric dissections) to investigate the incidence of this anomaly. RESULTS: We detected this variation in 3/325 (1%) of DIEP flaps following preoperative computed tomography. In 1/50 (2%) of the cadaveric specimens, a peritoneal-cutaneous perforator was found and injected with lead oxide contrast. It was shown to fill the cutaneous veins of the majority of the lower abdominal integument. CONCLUSION: Peritoneal-cutaneous perforators are rare anatomical variations (4/375: 1.1%) that may have significant ramifications for surgery utilizing the vasculature of the abdominal wall. CTA was significantly able to detect this anomaly and aid operative planning. Preoperative CTA helps to safely identify individual vascular anatomy including rare variations.

ABSTRACT

UNLABELLED: The use of perforator flaps in breast reconstructions has increased considerably in the past decade. A disadvantage of the perforator flap is difficult dissection, which results in a longer procedure. During spring 2006, we introduced CT angiography (CTA) as part of the diagnostic work-up in perforator flap reconstructions to visualise each perforator more accurately. The main objectives were to reduce surgery time and the number of complications. A chart review was conducted 1 year after CTA introduction to investigate if these objectives were met. MATERIALS AND METHODS: Patients with a deep inferior epigastric perforator (DIEP) flap who underwent preoperative analysis through CTA were retrospectively evaluated. The population
