RESUMEN

BACKGROUND: Three-dimensional (3D) contrast-enhanced magnetic resonance angiography (CEMRA) is routinely used for vascular evaluation. With existing techniques for CEMRA, diagnostic image quality is only obtained during the first pass of the contrast agent or shortly thereafter, whereas angiographic quality tends to be poor when imaging is delayed to the equilibrium phase. We hypothesized that prolonged blood pool contrast enhancement could be obtained by imaging with a balanced T1 relaxation-enhanced steady-state (bT1RESS) pulse sequence, which combines 3D balanced steady-state free precession (bSSFP) with a saturation recovery magnetization preparation to impart T1 weighting and suppress background tissues. An electrocardiographic-gated, two-dimensional-accelerated version with isotropic 1.1-mm spatial resolution was evaluated for breath-hold equilibrium phase CEMRA of the thoracic aorta and heart. METHODS: The study was approved by the institutional review board. Twenty-one subjects were imaged using unenhanced 3D bSSFP, time-resolved CEMRA, first-pass gated CEMRA, followed by early and late equilibrium phase gated CEMRA and bT1RESS. Nine additional subjects were imaged using equilibrium phase 3D bSSFP and bT1RESS. Images were evaluated for image quality, aortic root sharpness, and visualization of the coronary artery origins, as well as using standard quantitative measures. RESULTS: Equilibrium phase bT1RESS provided better image quality, aortic root sharpness, and coronary artery origin visualization than gated CEMRA (P < 0.05), and improved image quality and aortic root sharpness versus unenhanced 3D bSSFP (P < 0.05). It provided significantly larger apparent signal-to-noise and apparent contrast-to-noise ratio values than gated CEMRA and unenhanced 3D bSSFP (P < 0.05) and provided ninefold better fluid suppression than equilibrium phase 3D bSSFP. Aortic diameter and main pulmonary artery diameter measurements obtained with bT1RESS and first-pass gated CEMRA strongly correlated (P < 0.05). CONCLUSIONS: We found that using bT1RESS greatly prolongs the useful duration of blood pool contrast enhancement while improving angiographic image quality compared with standard CEMRA techniques. Although further study is needed, potential advantages for vascular imaging include eliminating the current requirement for first-pass imaging along with better reliability and accuracy for a wide range of cardiovascular applications.

RESUMEN

GOAL: Readmissions are a significant financial burden for payers. Cardiovascular-related discharges are particularly prone to readmission. Posthospital discharge support can impact patient recovery and probably reduce patient readmissions. This study aimed to address the underlying behavioral and psychosocial factors that can negatively affect patients after discharge. METHODS: The study population was adult patients admitted to the hospital with a cardiovascular diagnosis who had a plan to discharge home. Those who consented to participate were randomized to intervention or control groups on a 1:1 basis. The intervention group received behavioral and emotional support, whereas the control group received usual care. Interventions included motivational interviewing, patient activation, empathetic communication, addressing mental health and substance use, and mindfulness. PRINCIPAL FINDINGS: Observed total readmission costs were significantly lower in the intervention group than in the control group ($1.1 million vs. $2.0 million) as was the observed mean cost per readmitted patient ($44,052 vs. $91,278). The mean expected cost of readmission after adjustment for confounding variables was lower in the intervention group than in the control group ($8,094 vs. $9,882, p = .011). PRACTICAL APPLICATIONS: Readmissions are a costly spend category. In this study, posthospital discharge support addressing the psychosocial factors contributing to patients' readmissions resulted in a lower total cost of care for those with a cardiovascular diagnosis. We describe an intervention that is reproducible and can be scaled broadly through technology to reduce readmission costs.

RESUMEN

Current guidelines of aortic stenosis (AS) management focus on valve parameters, LV systolic dysfunction, and symptoms; however, emerging data suggest that there may be benefit of aortic valve replacement before it becomes severe by present criteria. Myocardial assessment using novel multimodality imaging techniques exhibits subclinical myocardial injury and remodeling at various stages before guideline-directed interventions, which predicts adverse outcomes. This raises the question of whether implementing serial myocardial assessment should become part of the standard appraisal, thereby identifying high-risk patients aiming to minimize adverse outcomes.

RESUMEN

BACKGROUND: We present a yet to be described association of SARS-CoV-2 infection with Kikuchi-Fujimoto disease. CASE PRESENTATION: A 32-year-old physician with history of SARS-CoV-2 infection presented to the emergency department with 2 weeks of fever, chills, and right sided cervical lymphadenopathy. He was treated empirically for presumed folliculitis with worsening of symptoms leading to repeat presentation to the emergency department. Extensive workup was unrevealing of an infectious cause and needle biopsy of the lesion was unrevealing. An excisional lymph node biopsy revealed follicular hyperplasia with necrotic foci showing abundance of histiocytes at the edge of necrosis with CD8 predominance of T-cells. Final diagnosis was deemed to be Kikuchi-Fujimoto disease. Antibiotic therapy was discontinued, and the patient's symptoms resolved with steroid therapy and expectant management. CONCLUSIONS: This is the first report of a patient developing Kikuchi-Fujimoto disease following SARS-CoV-2 infection. Clinicians should be aware of Kikuchi-Fujimoto disease as a possibility when approaching patients with hyper-inflammatory states who present with cervical lymphadenopathy.

RESUMEN

Solanum trilobatum Linn is a medicinal plants used in India from many centuries to cure various diseases. The purpose of the study is to evaluate the ameliorative potential of the ethanolic leaf extract and fractions of Solanum trilobatum (St) against alloxan induced diabetic rats. Solanum trilobatum leaf extract and fractions were administered orally at two different concentration (100-200mg/kg body weight) to alloxan induced diabetic rats. The antidiabetic efficacy was validated through various biochemical parameters, enzyme assays, renal markers and antioxidant properties were also determined. The phytochemical analyses of St leaves were done by estimating their Chlorophyll, carotenoids, total sugar, protein, amino acid and minerals contents. The results revealed that the leaf extracts and fractions of St were efficient anti hyperglycemic agents and posses potent nephro-protective activity. However, the extracts of St leaves at a concentration of 200mg/kg bw exhibit higher efficacy in all tested concentrations. From the result it can be concluded that the leaf extracts of St can be a potential candidate in treating the hyperglycemic conditions and justifies its use in ethano medicine and can be exploits in the management of diabetes.

RESUMEN

BACKGROUND: Lean metabolic dysfunction-associated steatotic liver disease (MASLD), characterized by a BMI < 25 kg/m² (or < 23 kg/m² in Asians), presents a challenging prognosis compared to non-lean MASLD. This study examines cardiovascular outcomes in both lean and non-lean MASLD cohorts. METHODS: In this meta-analysis, pooled odds ratios (ORs) within 95 % confidence intervals (CIs) were calculated for primary outcomes (cardiovascular mortality and major adverse cardiovascular events [MACE]) and secondary outcomes (cardiovascular disease [CVD], all-cause mortality, hypertension, and dyslipidemia). Studies comparing lean and non-lean MASLD within the same cohorts were analyzed, prioritizing those with larger sample sizes or recent publication dates. RESULTS: Twenty-one studies were identified, encompassing lean MASLD patients (n = 7153; mean age 52.9 ± 7.4; 56 % male) and non-lean MASLD patients (n = 23,514; mean age 53.2 ± 6.8; 63 % male). Lean MASLD exhibited a 50 % increase in cardiovascular mortality odds compared to non-lean MASLD (OR: 1.5, 95 % CI 1.2-1.8; p < 0.0001). MACE odds were 10 % lower in lean MASLD (OR: 0.9, 95 % CI 0.7-1.2; p = 0.7), while CVD odds were 40 % lower (p = 0.01). All-cause mortality showed a 40 % higher odds in lean MASLD versus non-lean MASLD (p = 0.06). Lean MASLD had 30 % lower odds for both hypertension (p = 0.01) and dyslipidemia (p = 0.02) compared to non-lean MASLD. CONCLUSION: Despite a favorable cardiometabolic profile and comparable MACE rates, lean individuals with MASLD face elevated cardiovascular mortality risk.

RESUMEN

Data on utilization and safety of mitral Transcatheter Edge-to-Edge Repair (TEER) among hypertrophic cardiomyopathy (HCM) patients is limited. Our study aimed to assess the national utilization, safety, and clinical outcomes of TEER procedures among HCM patients using a nationwide real-world cohort. HCM patients undergoing TEER hospitalizations between 2015-2020 were identified using ICD-10 (International Classification of Diseases, (ICD-10-CM/PCS). HCM-TEER and HCM No-TEER formed the two comparison groups. Demographic characteristics, baseline comorbidities, procedural complications, inpatient mortality, length of stay (LOS), and cost of hospitalization were compared between the propensity-matched cohorts. Numeric values of 10 or less were not reported per NIS data use agreements. A total of 39,625 weighted cases of TEER were identified from 2015-2020. Of the included patients, 335 patients had the HCM diagnosis. The median age of the HCM-TEER group was 74 (70-79) vs. 79 (72-85) for the no-TEER cohort. The TEER procedure was more frequently performed among Caucasians (86.57%) and females (53.73%). The TEER procedure among HCM patients had similar in-hospital mortality (Adjusted odds ratio: aOR 1.50, 95% CI [0.68-3.29]; p = 0.30) and net adverse cardiac events (NACE) (aOR 1.16, 95% CI [0.73-1.85]; p = 0.51). TEER among HCM was associated with higher odds of gastrointestinal/hematological (aOR 2.33, 95% CI [1.29-4.19]; p = 0.003) complications. However, the odds of cardiac complications (aOR 0.57, 95% CI [0.33-0.96]; p = 0.03) were not higher. The median length of stay was similar in both the groups (median: 2 vs. 2, p = 0.74), although TEER among HCM was associated with higher costs of hospitalization ($44729.36 vs. $40513.82, p < 0.01). TEER is a minimally invasive procedure and could be a safe option for symptomatic HCM patients with significant MR who are poor surgical candidates. Mitral TEER among HCM has been increasingly utilized in recent years in the United States more commonly in obstructive HCM and is associated with no difference in mortality and net adverse cardiac events but higher odds for gastrointestinal/hematological complications than non-HCM patients.

RESUMEN

INTRODUCTION: Takotsubo syndrome (TTS), also known as stress-induced cardiomyopathy, can be complicated by shock. The outcomes of patients with TTS complicated with cardiogenic shock (CS) versus mixed cardiogenic and septic shock (MS) is not known. METHODS: We queried Nationwide Inpatient Sample (NIS) from 2009-2020 to compare TTS patients with CS and MS using International Classification of Disease, Ninth & Tenth Edition, Clinical Modification (ICD- 9 & 10-CM) coding. In-hospital outcomes were compared using one: one propensity score matched (PSM) analysis. The primary outcome was in-hospital mortality. RESULTS: Of 23,126 patients with TTS 17,132 (74%) had CS, and 6,269 (26%) had MS. The mean age was 67 years in CS and 66 years in MS, and majority of patients were female (n = 17,775, 77%). On adjusted multivariate analysis, MS patients had higher odds of in-hospital mortality (aOR 1.44, 95% CI 1.36-1.52), AKI (aOR 1.53, 95% CI 1.48-1.58), pressor requirement (aOR 1.37, 95% CI 1.25-1.50). However, had lower odds of MCS use (aOR 0.44, 95% CI 0.40-0.48) and cardiac arrest (aOR: 0.81, 95% CI 0.73-0.90) (p-value <0.0001). Mean LOS and inflation-adjusted hospital charges were higher in MS. CONCLUSION: MS in the setting of TTS have higher rates of in-hospital mortality, AKI, and pressor requirements.

RESUMEN

End-stage renal disease (ESRD) and atrial fibrillation (AF) are commonly encountered, with ESRD itself serving as a well-established risk factor for AF.1 The 2018 AF guidelines have recommended apixaban across all the spectrums of renal impairment, including patients on hemodialysis (HD), and the 2019 American Heart Association/American College of Cardiology/Heart Rhythm Society updated guidelines have suggested careful consideration of reduced dose of direct oral anticoagulants (DOACs) in patients with ESRD.2,3 The current data on the safety and efficacy of warfarin versus DOACs in patients with AF with ESRD and HD is variable. This study aimed to perform a study-level meta-analysis to evaluate the effectiveness and safety of warfarin and DOACs in patients with AF who require dialysis.
