Fully automated quantitative coronary angiography versus optical coherence tomography guidance for coronary stent implantation (FLASH): Study protocol for a randomized controlled noninferiority trial. Am Heart J 2024; 275:86-95. [PMID: 38723880 DOI: 10.1016/j.ahj.2024.05.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Revised: 05/05/2024] [Accepted: 05/05/2024] [Indexed: 07/01/2024]
Abstract
BACKGROUND Artificial intelligence-based quantitative coronary angiography (AI-QCA) has been developed to provide a more objective and reproducible data about the severity of coronary artery stenosis and the dimensions of the vessel for intervention in real-time, overcoming the limitations of significant inter- and intraobserver variability, and time-consuming nature of on-site QCA, without requiring extra time and effort. Compared with the subjective nature of visually estimated conventional CAG guidance, AI-QCA guidance provides a more practical and standardized angiography-based approach. Although the advantage of intravascular imaging-guided PCI is increasingly recognized, their broader adoption is limited by clinical and economic barriers in many catheterization laboratories. METHODS The FLASH (fully automated quantitative coronary angiography versus optical coherence tomography guidance for coronary stent implantation) trial is a randomized, investigator-initiated, multicenter, open-label, noninferiority trial comparing the AI-QCA-assisted PCI strategy with optical coherence tomography-guided PCI strategy in patients with significant coronary artery disease. All operators will utilize a novel, standardized AI-QCA software and PCI protocol in the AI-QCA-assisted group. A total of 400 patients will be randomized to either group at a 1:1 ratio. The primary endpoint is the minimal stent area (mm2), determined by the final OCT run after completion of PCI. Clinical follow-up and cost-effectiveness evaluations are planned at 1 month and 6 months for all patients enrolled in the study. RESULTS Enrollment of a total of 400 patients from the 13 participating centers in South Korea will be completed in February 2024. Follow-up of the last enrolled patients will be completed in August 2024, and primary results will be available by late 2024. CONCLUSION The FLASH is the first clinical trial to evaluate the feasibility of AI-QCA-assisted PCI, and will provide the clinical evidence on AI-QCA assistance in the field of coronary intervention.

Abstract
Frailty and malnutrition in patients with heart failure are barriers to durable left ventricular assist device (D-LVAD) support and heart transplantation. Moreover, cachexia in patients with advanced heart failure carries a high mortality risk. There are no guidelines for these patients other than increased caloric intake and rehabilitation. Patients suffering from cardiac cachexia and heart failure may benefit from temporary, percutaneous assist device support to improve the underlying heart disease and reverse the catabolic state. We retrospectively reviewed patients from January 2017 to January 2022. All patients who received Impella support (5.0 or 5.5, Abiomed) before D-LVAD implantation were screened. Those who met the criteria for cardiac cachexia were included. Patient demographics, nutritional and biochemical markers, and survival data were collected. A total of 14 patients were included. The majority of patients were male (85.7%) with ischemic cardiomyopathy (64.3%). Caloric intake, physical strength, and ambulation improved. Prealbumin levels improved from a median of 13.7-18.0 mg/dl ( p < 0.006) while on Impella 5.0 or 5.5 support. All patients survived to discharge and the 6 month follow-up. In conclusion, use of the Impella device improves cardiogenic shock symptoms and, consequently, may improve cachexia status prior to D-LVAD implantation.

Comparison of the Effects of Inorganic or Amino Acid-Chelated Zinc on Mouse Myoblast Growth in vitro and Growth Performance and Carcass Traits in Growing-Finishing Pigs. Front Nutr 2022; 9:857393. [PMID: 35464034 PMCID: PMC9021508 DOI: 10.3389/fnut.2022.857393] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Accepted: 02/28/2022] [Indexed: 11/16/2022] Open
Abstract
This study aimed to investigate the effects of the supplementation of different sources of zinc on mouse myoblast growth in vitro and the growth performance and carcass traits in growing-finishing pigs. In the in vitro trial, 25 or 75 mM zinc sulfate (ZnSO4), methionine-chelated zinc (ZnMet), and glycine-chelated zinc (ZnGly) were co-cultured with the myoblast during proliferation and differentiation. The results showed that the amino acid-chelated zinc supplementation, especially ZnMet, enhances cell proliferation and differentiation in mouse myoblast, and regulates the distribution in S and G2/M phases (P < 0.05). Meanwhile, the protein expression levels of the mammalian target of rapamycin pathways were up-regulated after treatment with 25 μM ZnMet (P < 0.05), which is consistent with the results of the enriched Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway in the transcriptome analysis. In the in vivo trial, 27 Duroc × (Landrace × Large White) pigs with an initial average weight of 31.62 ± 0.36 kg were divided into three groups with nine replicates per treatment. The dietary treatment groups were as follows: (1) ZnSO4 group, basal diet +75 mg/kg ZnSO4; (2) ZnMet group, basal diet +75 mg/kg ZnMet; and (3) ZnGly group, basal diet +75 mg/kg ZnGly. The whole trial lasted for 75 days. Increased final body weight, average daily gain, and decreased F/G were noted in the ZnMet group (P < 0.05). Moreover, the ZnMet group had higher carcass weight and loin eye area (P = 0.05). The ZnMet and ZnGly group both had lower serum total protein (P < 0.05), while the ZnMet group had higher serum alkaline phosphatase (P < 0.05). Also, the addition of ZnMet showed higher concentrations of zinc and iron in muscle, kidney, and serum (P < 0.05), improving the deposition and availability of micronutrients. In conclusion, amino acid-chelated zinc, particularly ZnMet, had the best effect, which could improve growth in vitro and increase growth performance while boosting bioavailability in growing-finishing pigs, ultimately, enhancing muscle mass, providing a theoretical basis and guidance for the future use of amino acid-chelated zinc to effectively replenish energy in animal nutrition and production.

Abstract
BACKGROUND Hypoalbuminemia (HA) is common in HF, however, its pathophysiology and clinical implications are poorly understood. While multiple studies have been published in the past decade investigating the role of serum albumin in HF, there is still no consensus on the prognostic value of this widely available measure. The objective of this study is to assess the prognostic role of albumin in heart failure (HF) patient. METHODS Unrestricted searches of MEDLINE, EMBASE, Cochrane databases were performed. The results were screened for relevance and eligibility criteria. Relevant data were extracted and analyzed using Comprehensive Meta-Analysis software. The Begg and Mazumdar rank correlation test was utilized to evaluate for publication bias. RESULTS A total of 48 studies examining 44,048 patients with HF were analyzed. HA was found in 32% (95% confidence interval [CI] 28.4%-37.4%) HF patients with marked heterogeneity (I2 = 98%). In 10 studies evaluating acute HF, in-hospital mortality was almost 4 times more likely in HA with an odds ratios (OR) of 3.77 (95% CI 1.96-7.23). HA was also associated with a significant increase in long-term mortality (OR: 1.5; 95% CI: 1.36-1.64) especially at 1-year post-discharge (OR: 2.44; 95% CI: 2.05-2.91; I2 = 11%). Pooled area under the curve (AUC 0.73; 95% CI 0.67-0.78) was comparable to serum brain natriuretic peptide (BNP) in predicting mortality in HF patients. CONCLUSION Our results suggest that HA is associated with significantly higher in-hospital mortality as well as long-term mortality with a predictive accuracy comparable to that reported for serum BNP. These findings suggest that serum albumin may be useful in determining high-risk patients.

The contribution of cardiac and extracardiac factors to NT-proBNP concentrations in patients with advanced heart failure before and after left ventricular assist device implantation. Peptides 2021; 135:170420. [PMID: 33058962 DOI: 10.1016/j.peptides.2020.170420] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 09/18/2020] [Accepted: 09/26/2020] [Indexed: 12/28/2022]
Abstract
The clinical significance of N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients undergoing left ventricular assist device (LVAD) implantation is not fully explored. NT-proBNP concentrations are influenced by body composition, renal function and intracardiac pressures; dynamic measures pre- and post-LVAD implantation. We sought to identify the individual contribution of cardiac and extracardiac factors to NT-proBNP concentrations in advanced heart failure patients before and after LVAD implantation. We retrospectively collected data from 63 patients implanted with a LVAD with NT -proBNP measurements (2006-2019). Hemodynamic measurements were obtained through right heart catheterization (RHC). Univariable linear regression and multivariable stepwise regression models were used to analyze variables associated with NT-proBNP concentrations in the pre- and post-LVAD setting. Paired t-test was performed on a subpopulation of 13 patients with complete data. We found significant differences in all extracardiac (BMI, creatinine, eGFR) and all invasive hemodynamic measurements pre-LVAD compared to post-LVAD. NT-proBNP decreased by 83 %, in the subpopulation of 13 patients: 736 pmol/L [IQR 498-1330] to 126 pmol/L [IQR 74.8-241.7]. In multivariable analysis, only creatinine remained significantly associated with NT-proBNP before LVAD implant (p = 0.016), whereas pulmonary capillary wedge pressure (PCWP) was the only independent variable associated with NT-proBNP after LVAD implant (p < 0.0001). Creatinine and PCWP were the only independent factors associated with NT-proBNP concentrations before and after LVAD implantation, respectively. Invasive hemodynamic measurements were more closely associated with NT-proBNP concentration after LVAD than extracardiac factors and reversely pre-LVAD, suggesting that NT-proBNP serves as a useful biomarker of cardiac conditions post-LVAD implantation.

Abstract
BACKGROUND The negative impact of baseline hypoalbuminemia on clinical outcome following left ventricular assist device (LVAD) implantation is well known. However, the implications of perioperative change in serum albumin levels on post-LVAD outcomes remain uninvestigated. METHODS Among consecutive patients with baseline serum albumin <3.5 g/dl who received durable LVAD implantation between April 2014 and August 2017 and were followed for 1 year, the impact of perioperative change in serum albumin level from baseline to 3 months post-LVAD on the incidence of adverse events was investigated. RESULTS Sixty-eight patients (median 60 years and 69% male) were included. Serum albumin change was an independent predictor of the occurrence of adverse events with an adjusted hazard ratio of 0.32 (95% confidence interval, 0.13-0.78) and a cutoff change of 0.7 g/dl. Those with albumin increase >0.7 g/dl had higher 1-year freedom from adverse events (45% vs. 14%, p = .008), dominantly due to lower incidence of death or sepsis compared with those without (p < .05 for both). CONCLUSION Among those with baseline hypoalbuminemia, a considerable perioperative increase in serum albumin levels following LVAD implantation was associated with lower mortality and morbidity. The implication of aggressive nutrition intervention on LVAD patients is the next concern.
