RESUMEN
Study objective: Assessing if Transcatheter Edge to Edge Repair (TEER) with Mitraclip™ in patients with moderate to severe mitral regurgitation (MR) and cardiogenic shock (CS) improves outcomes compared to medical management alone. Design: A single-center, retrospective study was performed in an urban tertiary referral center. Setting: Rush University Medical Center, United States. Participants: Adult patients presenting with CS and moderate to severe MR between 2012 and 2021 were included. Interventions: Undergoing Mitral TEER with Mitraclip versus medical management alone. Main outcome measures: Major adverse cardiovascular events (MACE) defined as cardiovascular death, heart failure admission, stroke, and myocardial infarction assessed at 30 days, 6 months, and 1 year. The secondary outcome was a change in New York Heart Association (NYHA) classification at 30 days and 6 months. Results: There were 28 patients included in the medical management and 33 in the mitral valve TEER groups. There was a decreased MACE in the intervention group at 30 days (24.2 % vs. 46.4 %, p ≤0.001) and 6 months (27 % vs. 75 %, p = 0.002), though not at 1 year (29.4 % vs. 41.7 %, p = 0.42). At 30 days, more patients in the mitral valve TEER group improved to NYHA classes I/II compared to medical management alone (10 [35.7 %] vs. 16 [50 %], p = 0.043). There were no differences in NYHA classes I/II at 6 months (7 [43.7 %] vs. 13 [54.2 %], p = 0.63). Conclusion: Mitral valve TEER using the Mitraclip™ system improves mid-term cardiovascular compared to medical management alone in patients with CS but does not improve mortality.
RESUMEN
BACKGROUND: Compared to conventional cardiac troponin (cTn), the high-sensitivity cardiac troponin (hs-cTn) assay is associated with improved detection of myocardial infarction (MI). METHODS: We performed a descriptive retrospective analysis of resource utilization at Rush University Medical Center over the transition period (July 1, 2021) from a cTn to a hs-cTn assay. Inclusion criteria included emergency department (ED) encounters between January 1 to December 31, 2021, with chief complaints of "chest pain" or "dyspnea" with associated troponin orders. The primary endpoint was the percentage of ED discharges. Secondary endpoints included the number of cardiac studies ordered. Univariable comparisons of these endpoints were performed using Student's t-test for continuous variables and Chi-square tests for binary/categorical variables. RESULTS: A total of 5113 encounters were analyzed. Hs-cTn was associated with an overall increase in ED patient discharges with negative troponin tests (44.1% vs. 29.9%, P < 0.01). In terms of cardiac testing per encounter, hs-cTn was associated with significant increases in the number of troponin tests (1.9 vs. 1.6, P < 0.01), electrocardiograms (3.0 vs. 2.9, P = 0.01), and echocardiograms (0.5 vs. 0.4, P < 0.01). There was a significant decrease in the utilization of stress testing (0.21 vs. 0.26, P < 0.01). There was a significant increase in total coronary angiography use during the hs-cTn period compared to cTn (227/2471 (9.2%) vs. 195/2642 (7.4%), P = 0.02). CONCLUSION: Transitioning from cTn to hs-cTn was associated with significantly increased ED discharges and an increase in troponin tests, ECG, echocardiograms, and coronary angiograms. There was a decrease in the number of stress tests.

Acute right heart failure is a complication of inferior ST-elevation myocardial infarctions. Given the further hemodynamic instability that results from right-sided failure, a treatment option is needed to help bridge toward cardiac recovery. We present a case of using a right ventricular assist device in a patient who had marked improvement in cardiac function after an instance of acute right heart failure.
RESUMEN
Study objective: Study the clinical outcomes associated with the number of concomitant vasopressors used in critically ill COVID-19 patients. Design: A single-center retrospective cohort study was conducted on patients admitted with COVID-19 to the intensive care unit (ICU) between March and October 2020. Setting: Rush University Medical Center, United States. Participants: Adult patients at least 18 years old with COVID-19 with continuous infusion of any vasopressors were included. Main outcome measures: 60-day mortality in COVID-19 patients by the number of concurrent vasopressors received. Results: A total of 637 patients met our inclusion criteria, of whom 338 (53.1 %) required the support of at least one vasopressor. When compared to patients with no vasopressor requirement, those who required 1 vasopressor (V1) (adjusted odds ratio [aOR] 3.27, 95 % confidence interval (CI) 1.86-5.79, p < 0.01) (n = 137), 2 vasopressors (V2) (aOR 4.71, 95 % CI 2.54-8.77, p < 0.01) (n = 86), 3 vasopressors (V3) (aOR 26.2, 95 % CI 13.35-53.74 p < 0.01) (n = 74), and 4 or 5 vasopressors(V4-5) (aOR 106.38, 95 % CI 39.17-349.93, p < 0.01) (n = 41) were at increased risk of 60-day mortality. In-hospital mortality for patients who received no vasopressors was 6.7 %, 22.6 % for V1, 27.9 % for V2, 62.2 % for V3, and 78 % for V4-V5. Conclusion: Critically ill patients with COVID-19 requiring vasopressors were associated with significantly higher 60-day mortality.
RESUMEN
Introduction: Patients with pre-existing cardiovascular disease may carry a higher risk for mortality from COVID-19. This study examined the association between individuals with pre-existing cardiovascular disease admitted for COVID-19 and their clinical outcomes. Methods: A retrospective cohort study was conducted on patients admitted with COVID-19 to Rush University System for Health (RUSH) to identify cardiovascular risk factors associated with increased mortality and major adverse cardiovascular events (MACE; a composite of cardiovascular death, stroke, myocardial injury, and heart failure exacerbation). Multivariable logistic regression was used to adjust for demographic data and comorbid conditions. Results: Of the 1682 patients who met inclusion criteria, the median age was 59. Patients were predominantly African American (34.4 %) and male (54.5 %). Overall, 202 (12 %) patients suffered 60-day mortality. In the multivariable model that assessed risk factors for 60-day mortality, age 60-74 (adjusted odds ratio [aOR] 3.30 [CI: 1.23-10.62]; p < 0.05) and age 75-100 (aOR 4.52 [CI: 1.46-16.15]; p < 0.05) were significant predictors when compared to those aged 19 to 39. This model also showed that those with past medical histories of atrial fibrillation (aOR 2.47 [CI: 1.38-4.38]; p < 0.01) and venous thromboembolism (aOR 2.00 [CI: 1.12-3.50]; p < 0.05) were at higher risk of 60-day mortality. Conclusion: In this cohort, patients over 60 years old with a pre-existing history of atrial fibrillation and venous thromboembolism were at increased risk of mortality from COVID-19.
RESUMEN
Cardiovascular disease (CVD) is the leading cause of mortality worldwide yet, despite advances in treatment, CVD remains an underestimated and undermanaged condition, with an even greater risk in Type 2 Diabetes Mellitus (T2DM). Sodium-Glucose Cotransporter-2 Inhibitors (SGLT-2i) are a promising novel drug class reported to improve Cardiovascular (CV) and renal outcomes in T2DM. Recent large-scale trials have assessed their CV safety with unexpected findings of multiple systemic benefits that could potentially reverse CVD. In this systematic review, we examined ten Randomized Controlled Trials (RCTs) that looked at cardiovascular outcomes in Type 2 diabetics and SGLT-2i. The RCTs were appropriately screened, looking for clear primary or secondary outcomes on CV events, and compared with placebo or other antidiabetic drugs. The RCTs had an average sample population studied of 5,549 participants with a mean follow-up time of 2.66 years. Three of the studies focused on CV parameters and risk factors. The remaining had defined CV composite events, and all consistently observed at least one CV benefit when using SGLT-2i. Our review of SGLT-2i in Type 2 diabetics showed the greatest benefit in reducing Heart Failure (HF) exacerbation and modest lowering of CV complications in high CV risk participants. Overall, there is still uncertainty about the exact mechanisms of SGLT-2i in their CV benefit, and whether they would favor pre-diabetic populations and those at earlier stages of CVD.
RESUMEN
Rheumatoid arthritis (RA) is a chronic destructive type of arthritis. It has a high prevalence in females as compared to the male population globally. It mainly affects the synovium of peripheral joints and leads to the destruction of joints with time. Patients with RA usually have a high burden of inflammation which may lead to certain physical disabilities and debilitating effects on mental health and cognitive ability. The question we investigated here in this systematic review is how changing lifestyles and increasing exercise or physical activities affects one's cognitive abilities. This article adheres to preferred reporting items for systematic review and meta-analyses (PRISMA) guidelines. We used different databases such as PubMed, MEDLINE, and ScienceDirect to find relevant articles. To ensure the quality of the finally selected 12 studies, we followed different quality appraisal tools. Based on our review, we found out that increasing physical activities and aerobic exercises positively increase overall well-being and decrease the inflammatory load, which will ultimately positively impact cognitive function in this subgroup of patients. We also discover certain key players affecting motivation, perception, and adherence to physical activities. We encourage future studies to be done on this topic to help in increasing quality of life and increasing independence in this group of patients. Counseling and addressing patient concerns are very important and keep disease activity well controlled so that physical activities become feasible.
RESUMEN
3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase inhibitors are commonly used drugs in the management of elevated lipid levels and cardiovascular disease. In cardiovascular diseases, among other common chronic conditions, inflammatory biomarkers are used to monitor disease progression and the risk of recurrent adverse events. We explored whether or not there was a positive effect on these biomarkers using HMG-CoA reductase inhibitors. The systematic review was conducted by gathering relevant papers mainly from three databases, identified through a generated Medical Subject Headings (MeSH) strategy. Identification of papers was subsequently followed by applying a selected inclusion and exclusion criteria to narrow the papers chosen for review. Post the application of stipulated criteria, 12 papers remained. They were subsequently assessed for risk of bias using a Cochrane risk analysis tool, identifying most as having some concerns of bias or low risk of bias. We found that HMG-CoA reductase inhibitors exhibit both a lipid-lowering effect addition to an anti-inflammatory effect.
RESUMEN
Hypertrophic cardiomyopathy (HCM) is a genetically acquired disease of cardiac myocytes. Studies show that 70% of this disease is a result of different mutations in various sarcomere genes. This review aims to discuss several genetic mutations, epigenetic factors, and signal transduction pathways leading to the development of HCM. In addition, this article elaborates on recent advances in gene therapies and their implications for managing this condition. We start by discussing the founding mutations in HCM and their effect on power stroke generation. The less explored field of epigenetics including methylation, acetylation, and the role of different micro RNAs in the development of cardiac muscle hypertrophy has been highlighted in this article. The signal transduction pathways that lead to gene transcription, which in turn lead to increased protein synthesis of cardiac muscle fibers are elaborated. Finally, the microscopic events leading to the pathophysiologic macro events of cardiac failure, and the current experimental trials of gene therapy models, and the clustered regularly interspaced short palindromic repeats (CRISPR) type 2 system proteins, are discussed. We have concluded our discussion by emphasizing the need for more studies on epigenomics and experimental designs for gene therapy in HCM patients. This review focuses on the process of HCM from initial mutation to the development of phenotypic expression and various points of intervention in cardiac myocardial hypertrophy development.
RESUMEN
Digital microscopy (DM) is one of the cutting-edge advances in pathology, which entails improved efficiency, diagnostic advantages, and potential application in virtual diagnosis, particularly in the current era of the coronavirus disease (COVID-19) pandemic. However, the diagnostic challenges are the remaining concerns for its wider adoption by pathologists, and these concerns should be addressed in a specific subspecialty. We aim to identify the common diagnostic pitfalls of whole slide imaging (WSI), one modality of DM, in gastrointestinal (GI) pathology. From validating studies of primary diagnosis performance, we included 16 records with features on GI cases involved, at least two weeks wash-out periods, and more than 60 case study designs. A tailored quality appraisal assessment was utilized to evaluate the risks of bias for these diagnostic accuracy studies. Furthermore, due to the highly heterogeneous studies and unstandardized definition of discordance, we extract the discordant cases in GI pathology and calculate the discrepant rate, resulting from 0.5% to 64.28%. Targeting discrepancy cases between digital microscopy and light microscopy, we demonstrate five main diagnostic pitfalls regarding WSI as follows: additional time to review slides in WSI, hard to identify dysplasia nucleus, missed organisms like Helicobacter pylori (H. pylori), specific cell recognitions, and technical issues. After detailed reviews and analysis, we generate two essential suggestions for further GI cases signing out by DM. One is to use systematized 20x scans for diagnostic workouts and requesting 40x or even 60x scans for challenging cases; another is that a high-volume slides training should be set before the real clinical application of WSI for primary diagnosis, particularly in GI pathology.
RESUMEN
The use of cardiopulmonary bypass (CPB) in cardiac surgery often leads to a systemic inflammatory response. Up to 25% of patients undergoing CPB for cardiac surgery are reported to develop vasoplegic syndrome in the acute postoperative period, in which the patients are refractory to vasopressors. The purpose of this study is to assess vitamin D deficiency as a risk factor for vasoplegia after using CPB. We performed a retrospective review of 1322 patients undergoing adult cardiac surgery requiring CPB. Forty-six patients with previously recorded 25-hydroxy vitamin D (25(OH)D) levels within 6 months of surgery met the conditions of this study. The mean level of 25(OH)D was 32.7 ng/mL (standard deviation [SD] = 15.1). The mean age of patients was 67 (SD = 10.1) years old, most were male (63%) and white (78%). Average CPB time was 140 ± 44 minutes. Postoperative vasopressor use was compared to individual preoperative 25(OH)D levels. As a secondary end point, postoperative vasopressor use and vasoplegia were analyzed between 3 groups: Vitamin D deficient defined as 25(OH)D ≤20 ng/mL (n = 7), vitamin D insufficient defined as 25(OH)D between 20 and 29 ng/mL (n = 15), and vitamin D sufficient defined as 25(OH)D ≥30 ng/mL (n = 24). There was no correlation between vitamin D levels and postoperative vasopressor use. The mean doses of postoperative vasopressor use were 0.088 µg/kg/min (standard error of the mean [SEM] = 0.032), 0.085 µg/kg/min (SEM = 0.037), and 0.072 µg/kg/min (SEM = 0.024) of norepinephrine equivalents for the vitamin D deficient, insufficient, and sufficient groups, respectively. Incidence of vasoplegia for each group was the following: 0.143 for vitamin D deficient, 0.067 for vitamin D insufficient, and 0.125 for vitamin D sufficient. In this pilot study, there does not appear to be a relationship between vitamin D and vasopressor use following cardiac surgery utilizing CPB; however, there appears to be a trend toward an increased vasopressor usage in patients with decreased vitamin D levels. A larger sample size and a prospective analysis are warranted to further assess the significance of the relationship between vasoplegia and vitamin D deficiency. With further investigation, vitamin D has the potential to become a low-cost, low-risk therapeutic for improving outcomes in CPB surgery.
