• Lipoprotein(a) and aortic diseases: Epidemiological evidence from observation to causation.
    3 days ago
    Aortic aneurysm and dissection (AA/AD) are life-threatening vascular diseases with high mortality, yet no effective drugs to delay progression. Lipoprotein(a) [Lp(a)] is genetically determined and associated with atherosclerotic disease, but high-quality evidence on its causal role in AA/AD remains limited.

    To investigate the association between Lp(a) and AA/AD and assess potential causal relationships with major aortic disease subtypes.

    A prospective cohort of 312,332 UK Biobank participants was analyzed. Kaplan-Meier curves, Cox regression, and Fine-Gray competing-risk models assessed associations between Lp(a) and incident AA/AD. Two-sample Mendelian randomization (MR) analyses evaluated the potential causal effects of Lp(a) on AA, abdominal aortic aneurysm (AAA), thoracic aortic aneurysm (TAA), and AD.

    During a median follow-up of 16.5 years, 3122 AA/AD events occurred. Elevated Lp(a) independently predicted AA/AD with a dose-response relationship (hazard ratio [HR] = 1.40 for >180 vs <50 nmol/L; HR = 1.15 per 75 nmol/L increment). Competing-risk analyses yielded consistent results. MR analyses supported a causal association between Lp(a) and AA (odds ratio [OR] = 1.31, 95% CI: 1.08-1.62) and AAA (OR = 1.80, 95% CI: 1.37-2.37), whereas MR analyses did not provide sufficient evidence for causal associations with TAA or AD.

    Lp(a) may serve as a promising biomarker for risk assessment and stratification in aortic disease. However, the MR analysis for AD was limited by low statistical power, and the clinical utility of Lp(a) measurement requires further investigation.

  • Workday-rescheduling effects on ST-segment elevation myocardial infarction: a registry study analysis.
    3 days ago
    This study assessed whether China's workday-rescheduling policy is associated with short-term and long-term outcomes in patients with ST-segment elevation myocardial infarction (STEMI), particularly in occupational groups more likely to be affected by rescheduling.

    A prospective cohort study was conducted using data from the China Acute Myocardial Infarction registry between January 2013 and September 2014. A total of 15 854 STEMI patients were included. Since individual adherence to workday rescheduling is not directly measured in the registry, occupational category was used as a proxy to define groups more likely versus less likely to be affected by the workday-rescheduling policy. The primary outcome was in-hospital all-cause mortality. Secondary outcomes included in-hospital major adverse cardiovascular and cerebrovascular events (MACCE) and 2 year all-cause mortality. Multivariable logistic and Cox regression models were used for analysis.

    Using occupational category as a proxy for the likelihood of exposure to workday rescheduling, we stratified patients into a rescheduling-likely group (n=3141) and a rescheduling-unlikely group (n=12 713). Among patients in the rescheduling-likely occupational group, in-hospital mortality was significantly higher during abnormal workdays than conventional weekdays (7.8% vs 3.44%; adjusted OR=3.01; 95% CI 1.40 to 6.45). Two-year mortality was also higher (adjusted HR=1.99; 95% CI 1.20 to 3.30). Among 12 713 patients in the rescheduling-unlikely occupational group, no significant mortality differences were observed across temporal groups. Within the rescheduling-likely group, baseline characteristics and care quality indicators were generally comparable across the four temporal groups.

    Workday-rescheduling-induced abnormal work cycles are associated with higher in-hospital and 2 year adverse events in affected ST-segment elevation myocardial infarction patients. These findings should be interpreted as heterogeneity in the association between abnormal workdays and mortality by occupational likelihood of rescheduling exposure rather than as a direct individual-level causal effect of rescheduling.

  • Non-traumatic spinal cord ischaemia - Surfer's myelopathy.
    3 days ago
    A previously healthy surfer apprentice in his late 30s presented to our emergency department with acute paraplegia and loss of sensation in the lower limbs following sudden back pain during his third surfing lesson. The patient reported a hyperextension movement of the back while trying to stand up on the surfboard. On examination, he was classified as grade A on the American Spinal Injury Association (ASIA) Impairment Scale, with a sensory level at T10, hypotonic paraplegia, urinary retention and constipation. T2-weighted MRI revealed hyperintensity in the central spinal cord between T7 and T10 and a T11 focus of restricted diffusion compatible with spinal cord ischaemia. CT angiography of the thoracic and lumbar spine showed stenosis and occlusion of segmental arteries at the T11-T12, T12-L1 and L1-L2 levels. After extensive work-up, a diagnosis of surfer's myelopathy was made. The patient underwent antiplatelet treatment, high-dose methylprednisolone and early rehabilitation, but no major improvement was noted in the first 3 weeks. After 8 weeks of rehabilitation, the patient was able to dorsiflex and plantarflex the feet, as well as flex the legs, but remained unable to walk. Bilateral hypoaesthesia persisted and he had not regained anal or urinary sphincter control. He is now classified as ASIA D, and the MRI demonstrated complete resolution of the signal abnormalities after 8 weeks. Our case describes this non-traumatic entity with angiographic documentation of multiple vascular occlusions, which has rarely been reported in the literature and is thought to be secondary to arterial wall dissection and/or in situ thrombosis due to hyperextension and sudden movement of the back.

    Buerger's disease, or thromboangiitis obliterans, is a rare vascular disorder closely linked to smoking. It can cause severe ischemic pain, trophic disorders, and a high risk of amputation. Its management requires a specialized, multidisciplinary, and patient-centered approach. Drawing on the testimony of Nicolas Robin, a patient receiving vascular care, this article highlights the clinical, functional, psychological, and social consequences of this condition, as well as the challenges involved in the care pathway.

    Vascular diseases represent a major public health challenge due to their high prevalence and their functional and skin-related complications. Their management relies on a comprehensive approach that combines medication, appropriate physical activity, and lifestyle changes, with diet playing a central role. Tailored nutritional support is therefore a key therapeutic tool for promoting wound healing, preventing complications, and improving patients' quality of life. Nurses play an essential role in identifying at-risk situations, providing nutritional monitoring, and coordinating care throughout the patient's treatment journey.

  • Treatable traits approach for personalised management of sarcoidosis.
    3 days ago
    In sarcoidosis, personalised strategies that consider the various phenotypes and endotypes of the disease have the potential to improve patient care. The 'treatable traits' (TT) approach offers a promising strategy that has already been proposed and implemented in several other chronic pulmonary diseases. In this review, we propose five distinct TT categories for patients with sarcoidosis: aetiological, lifestyle, pulmonary, extrapulmonary (systemic) and comorbidities.Despite the potential of this strategy, several challenges hinder its implementation. In addition, much of the knowledge on the definition and prevalence of TTs comes from single-centre studies. Creating international registries will enhance our understanding and provide more accurate data on these traits.TTs are dynamic and require continuous evaluation to effectively respond to changes caused by disease progression or treatment response. A multidisciplinary management approach is therefore crucial as sarcoidosis can impact multiple organs. Integrating primary care physicians into the management framework will improve overall patient care.Incorporating patient preferences into the TT strategy is vital for improving adherence to treatment. Additionally, using patient-reported outcome measures will provide valuable insights into the impact of treatment.While the TT approach is feasible in developed healthcare systems, challenges exist in resource-limited settings. Advancing patient-centred care towards 5P medicine involves addressing key TTs that meet the unique patient needs.Therefore, randomised controlled trials focused on TTs are needed. Our proposed TT strategy aims to enhance quality of life and outcomes for patients with sarcoidosis while increasing awareness of the importance of TTs among healthcare providers and advocacy groups.

  • Abstract: MRSA-Associated Acute Purulent Pericarditis: A Case Report.
    3 days ago
    Purulent pericarditis is a rare, but life-threatening condition occurring in roughly 27.7 cases of pericarditis per 100,000 population per year in developed countries. Gram positive cocci are the predominant causative pathogens with Staphylococcus aureus and Streptococcus species being the most common. Early recognition is essential in preventing complications such as cardiac tamponade, constrictive pericarditis, and effusive-constitutive pericarditis. Despite appropriate medical management including both drainage and antibiotics, mortality rates remain elevated and approximately 50% of cases are diagnosed postmortem.

    An 84-year-old male with a history of myelodysplastic syndrome, permanent atrial fibrillation and heart failure with preserved ejection fraction presented to the emergency department with sharp, left-sided chest pain radiating to the right shoulder, worsened by inspiration. A computed tomography angiogram performed to evaluate for pulmonary embolisms revealed a large pericardial effusion. Electrocardiogram (EKG) demonstrated low-voltage tachycardia. Transthoracic echocardiography showed a large circumferential pericardial effusion with fibrinous strands. The patient underwent pericardiocentesis with drainage of 450 cc of purulent fluid, followed by placement of a pericardial drain. Fluid analysis revealed a pH of 6.9 and 15,095 nucleated cells/μL with 89% neutrophils. Pericardial fluid and blood cultures were positive for MRSA. The patient was initiated on intravenous vancomycin and transesophageal echocardiography was negative for infective endocarditis. He was subsequently transitioned to daptomycin to complete a four-week course of antibiotics. Repeat blood cultures were negative.

    This case illustrates the diagnostic challenges and management considerations for MRSA-associated purulent pericarditis in a frail host. Early echocardiography and pericardiocentesis are critical in management. Despite source control and target antibiotics, mortality remains high in frail hosts.

  • Beyond the CHA2DS2VASc: Hypercoagulable States in Anticoagulated AF Patients.
    3 days ago
    Despite the proven efficacy of direct oral anticoagulants (DOACs) in preventing thrombus formation in atrial fibrillation (AF), thrombus formation may rarely occur even with appropriate anticoagulation. We report the case of a 70-year-old woman with a history of AF, initially on warfarin, who underwent percutaneous left atrial appendage closure with a Watchman FLX 27 mm device due to recurrent gastrointestinal bleeding. She subsequently developed multiple unprovoked deep venous thromboses, necessitating the reinitiation of rivaroxaban therapy. She presented to the hospital with complaints of lower abdominal pain. Although the CT abdomen and pelvis was not a dedicated cardiac study, the superior slices incidentally captured the inferior and posterior left atrium, revealing a lobulated soft-tissue density suspicious for thrombus. Labs included INR 1.8, APTT of 40, and D-dimer of 0.62. Transthoracic echocardiography could not visualize thrombus. Transesophageal echocardiography revealed a large mobile thrombus in the superior cavity of LA. The watchman device was well seated with no flow noted across the device. A hypercoagulability workup showed low levels of Protein S antigen at 21. She was placed on warfarin. Follow-up TEE in 3 months showed a decrease in the thrombus size. This case highlights the importance of evaluating an underlying hypercoagulable state when thrombus develops despite DOAC therapy. While DOACs prevent thrombus formation in atrial fibrillation, their failure should not be dismissed as incidental. Clinicians should pursue a hypercoagulability workup, especially when thromboembolic events appear disproportionate to the CHA₂DS₂-VASc score. Early identification of inherited or acquired thrombophilies can guide tailored and effective long-term management.

  • Optimizing Thrombolysis for Acute Ischemic Stroke: Adjunct Therapies and Multiple Dosing Strategies.
    3 days ago
    Intravenous thrombolysis (IVT) and endovascular thrombectomy (EVT) are the keystones of current treatment for acute ischemic stroke. Most IVT candidates harbor medium or distal arterial occlusions, while EVT targets large artery occlusions. However, both treatments often fail to achieve sustained recanalization, microvascular reperfusion, and optimal clinical outcomes. Supplementing IVT with antithrombotic therapies has not shown consistent benefit, and alternative lytics such as tenecteplase provide, at best, a marginal improvement in outcome compared with alteplase. This review summarizes current evidence on multiple dosing strategies of IVT, including repeat administration of IVT in non-EVT candidates and IVT or intra-arterial thrombolytics in combination with EVT. We discuss the physiologic, pharmacokinetic, and clinical rationale for these approaches, highlight results from key clinical trials, and identify knowledge gaps to guide future research. Emerging data support novel fibrinolytic agents, sequential IVT dosing, and adjunct intra-arterial thrombolysis as promising strategies to enhance reperfusion and functional recovery while maintaining safety.
