Article Synopsis
  • This study systematically reviewed the impact of postoperative computed tomography imaging factors on outcomes following acute type A aortic dissection repair, focusing on measurements like aortic diameter and growth rates.
  • A total of 68 studies involving 7,885 patients were analyzed, revealing that extended repairs led to better false lumen thrombosis and reduced reintervention rates, but did not significantly improve survival rates.
  • Key prognostic indicators identified for improved outcomes include complete false lumen thrombosis and stabilization of aortic diameter, with aortic growth rates particularly significant in the descending thoracic region; future research should further explore these factors for better patient management.

Cardiac troponin is extensively used as a biomarker in modern medicine due to its diagnostic capability for myocardial injury, as well as its predictive and prognostic value for cardiac diseases. However, heterophile antibodies, antitroponin antibodies, and macrotroponin complexes can be observed both in seemingly healthy individuals and patients with cardiac diseases, potentially leading to false positive or disproportionate elevation of cTn (cardiac troponin) assay results and introducing discrepancies in clinical interpretations with impact on medical management. In this review article, we describe the possible mechanisms of cTn release and the sources of variations in the assessment of circulating cTn levels.

Background: The determinants and prognostic value of high-sensitivity cardiac troponin T (hs-cTnT) among patients with a systemic right ventricle are largely unknown.

Methods And Results: Ninety-eight patients from the randomized controlled SERVE (Effect of Phosphodiesterase-5 Inhibition With Tadalafil on Systemic Right Ventricular Size and Function) trial were included. The correlation between baseline hs-cTnT concentrations and biventricular volumes and function quantified by cardiac magnetic resonance or cardiac multirow detector computed tomography was assessed by adjusted linear regression models.

Background: The Diamond-Forrester model was used extensively to predict obstructive coronary artery disease (CAD) but overestimates probability in current populations. Coronary artery calcium (CAC) is a useful marker of CAD, which is not routinely integrated with other features. We derived simple likelihood tables, integrating CAC with age, sex, and cardiac chest pain to predict obstructive CAD.

Background: Clinical practice guidelines for the management and convalescence of patients with spontaneous coronary artery dissection (SCAD) have yet to be developed. The targeted content, delivery, and outcomes of interventions that benefit this population remain unclear. Patient-informed data are required to substantiate observational research and provide evidence to inform and standardize clinical activities.

Sarcoidosis and systemic sclerosis are two inflammatory multisystemic disorders of unknown etiology that may be life-threatening especially when there is cardiac involvement. Both diseases may coexist, however, there are very few case reports of patients with both cardiac sarcoidosis and systemic sclerosis in the literature. We report the case of a 72-year-old female who was initially referred for dyspnea.

Electronic address:

Contrast-induced nephropathy (CIN) is an important complication of percutaneous coronary intervention (PCI). We investigated whether left ventricular end-diastolic pressure (LVEDP) in patients who underwent PCI might be additive to current risk stratification of CIN. Data from consecutive patients who underwent primary PCI for ST-elevation myocardial infarction between 2013 and 2018 at Western Health in Victoria, Australia were analyzed.

Background Early vascular aging (EVA) is associated with higher risk of adverse cardiovascular events and can be estimated noninvasively by assessing arterial hemodynamics. Women with a history of preeclampsia have increased risk of cardiovascular disease, but underlying mechanisms are incompletely understood. We hypothesized that women with a history of preeclampsia display persistent arterial abnormalities and EVA in the postpartum period.

Article Synopsis
  • - The study aims to assess the case-fatality rate (CFR) of major bleeding in patients on dual antiplatelet therapy (DAPT) after undergoing percutaneous coronary intervention (PCI) and to analyze how this rate varies based on the duration of DAPT.
  • - From a search of 2777 potential studies, 16 studies were included, revealing 823 major bleeding events with 91 being fatal among nearly 49,000 patients on DAPT, resulting in an overall CFR of 10.8%.
  • - The findings indicate that while fatal bleeding is often not reported in DAPT studies, the CFR is significant, particularly higher within the first 12 months, suggesting that shorter DAPT durations may

Background Diagnosis of congenital long-QT syndrome (LQTS) is complicated by phenotypic ambiguity, with a frequent normal-to-borderline resting QT interval. A 3-step algorithm based on exercise response of the corrected QT interval (QTc) was previously developed to diagnose patients with LQTS and predict subtype. This study evaluated the 3-step algorithm in a population that is more representative of the general population with LQTS with milder phenotypes and establishes sex-specific cutoffs beyond the resting QTc.

Background TAILOR-PCI (Tailored Antiplatelet Initiation to Lessen Outcomes due to decreased Clopidogrel Response After Percutaneous Coronary Intervention) studied genotype-guided selection of antiplatelet therapy after percutaneous coronary intervention versus conventional therapy with clopidogrel. The presence of loss-of-function alleles in patients treated with clopidogrel may be associated with increased risk for ischemic events. We report a prespecified sex-specific analysis of genotyping and associated cardiovascular outcomes from this study.

Therapy resistance is one of the biggest challenges facing clinical oncology. Despite a revolution in new anti-cancer drugs targeting multiple components of the tumour microenvironment, acquired or innate resistance frequently blunts the efficacy of these treatments. Non-invasive identification of drug-resistant tumours will enable modification of the patient treatment pathway through the selection of appropriate second-line treatments.

Article Synopsis
  • Patients who experience return of spontaneous circulation (ROSC) after an out-of-hospital cardiac arrest (OHCA) may require sedation for care, prompting a study on the use of volatile anesthetics versus conventional sedatives.
  • In a systematic review of 1,973 citations, three studies with 604 patients were included, showing uncertain effects of volatile agents on delirium, survival to discharge, and ICU length of stay, with some indications of shorter mechanical ventilation duration.
  • The conclusion suggested that while volatile anesthetics might lead to shorter ventilation times, the evidence is low quality, indicating a need for more research in this area.

Article Synopsis
  • Recent studies highlight the benefit of early mechanical circulatory support in cardiogenic shock but lack clear real-time therapeutic targets based on clinical data.
  • A post hoc analysis of the DOREMI trial found that lactate clearance can effectively predict in-hospital survival, with complete lactate clearance showing strong association with patient outcomes.
  • These findings support using lactate clearance as a viable treatment target for improving mortality rates in future cardiogenic shock treatments.

Background In TAILOR-PCI, genotype-guided selection of P2Y inhibitors after percutaneous coronary intervention did not significantly reduce the risk of ischemic events at 12 months. The Age, Body Mass Index, Chronic Kidney Disease, Diabetes, and Genotyping (ABCD-GENE) score identifies patients with high platelet reactivity on clopidogrel at increased risk of ischemic events. The aim of this study was to investigate the value of the ABCD-GENE score for tailoring P2Y inhibitor selection after percutaneous coronary intervention.
