Abstract

Objectives After orthopedic surgery , clinical outcomes are affected by comorbid cardiovascular diseases (CVDs) and low 25-hydroxy-vitamin D (25-(OH)D). Myocardial function was suggested to be influenced by both the pro-inflammatory cytokine tumour necrosis factor alpha (TNFα) and the marker of endothelial dysfunction asymmetric dimethylarginine (ADMA). Material and methods We investigated TNFα and ADMA changes in association with serum levels of vitamin D and cardiac function in 47 older adults after major orthopedic surgery. Subjects were characterized for biochemical profiles and transthoracic echocardiographic measures. Assessments were done before and after the correction of hypovitaminosis D through a 6-month supplementation with calcifediol started at post-operative rehabilitation. Results The means serum levels of both TNFα and ADMA reduced from 1.39 ± 0.47 pg/mL to 1.30 ± 0.37 pg/mL (P 0.05), respectively. Significant treatment effects were observed for systolic blood pressure ( P 0.05), left ventricular ejection function ( P 0.001), and calcemia ( P Conclusion After the normalization of low levels of vitamin D, we were able to observe a reduction of circulating TNFα and ADMA together with the amelioration of cardiac function. Even if our results suggest that vitamin D might exert cardiac effects indirectly through the decrease in cardio-inflammation and endothelial dysfunction, a better understanding of the precise molecular regulations should be better investigated.

Abstract

Heavily calcified coronary lesions remain a technical challenge and an important cause of stent under-expansion and then failure. We hereby present a successful case of combined rotational atherectomy and intravascular lithotripsy for the treatment of an un-dilatable, heavily calcified coronary stenosis.

Abstract

The rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the high fatality rate of coronavirus disease 2019 (COVID-19) have been putting a strain on the world since December 2019. Infected individuals exhibit unpredictable symptoms that tend to worsen if age is advanced, a state of malnutrition persists, or if cardiovascular comorbidities are present. Once transmitted, the virus affects the lungs and in predisposed individuals can elicit a sequela of fatal cardiovascular consequences. We aim to present the pathophysiology of COVID-19, emphasizing the major cellular and clinical manifestations from a cardiological perspective. As a roaming viral particle or more likely via the Trojan horse route, SARS-CoV-2 can access different parts of the body. Cardiovascular features of COVID-19 can count myocardial injuries, vasculitis-like syndromes, and atherothrombotic manifestations. Deviations in the normal electrocardiogram pattern could hide pericardial effusion or cardiac inflammation, and dispersed microthrombi can cause ischemic damages, stroke, or even medullary reflex dysfunctions. Tailored treatment for reduced ejection fraction, arrhythmias, coronary syndromes, macrothrombosis and microthrombosis, and autonomic dysfunctions is mandatory. Confidently, evidence-based therapies for this multifaceted nevertheless purely cardiological COVID-19 will emerge after the global assessment of different approaches.

Abstract

© 2020 Elsevier Ltd Background: Observational studies have suggested that accelerated surgery is associated with improved outcomes in patients with a hip fracture. The HIP ATTACK trial assessed whether accelerated surgery could reduce mortality and major complications. Methods: HIP ATTACK was an international, randomised, controlled trial done at 69 hospitals in 17 countries. Patients with a hip fracture that required surgery and were aged 45 years or older were eligible. Research personnel randomly assigned patients (1:1) through a central computerised randomisation system using randomly varying block sizes to either accelerated surgery (goal of surgery within 6 h of diagnosis) or standard care. The coprimary outcomes were mortality and a composite of major complications (ie, mortality and non-fatal myocardial infarction, stroke, venous thromboembolism, sepsis, pneumonia, life-threatening bleeding, and major bleeding) at 90 days after randomisation. Patients, health-care providers, and study staff were aware of treatment assignment, but outcome adjudicators were masked to treatment allocation. Patients were analysed according to the intention-to-treat principle. This study is registered at ClinicalTrials.gov (NCT02027896). Findings: Between March 14, 2014, and May 24, 2019, 27 701 patients were screened, of whom 7780 were eligible. 2970 of these were enrolled and randomly assigned to receive accelerated surgery (n=1487) or standard care (n=1483). The median time from hip fracture diagnosis to surgery was 6 h (IQR 4–9) in the accelerated-surgery group and 24 h (10–42) in the standard-care group (p

Abstract

Cardiovascular involvement in rheumatoid arthritis (RA) is common, although the true prevalence of cardiac abnormalities is difficult to measure, as much disease remains clinically silent. The pathogenesis of cardiac lesions in RA is related to the primary disorder of microcirculation with diffuse arteriolar and capillary lesions. Previous studies demonstrated that coronary flow reserve (CFR) is impaired in patients with connective tissue diseases (CTD). This review focuses on transthoracic Doppler echocardiography as a noninvasive method used to assess CFR in RA patients. CFR is early reduced in RA patients without clinical evidence of heart disease as a result of impaired microcirculation. CFR seems a useful technique able to follow-up and to assess effects of new drugs on RA patients.

Abstract

Background. Some degree of cardiovascular disease should be suspected in young adults who have been paediatric renal transplant recipients also if no systematic data collection is routinely performed in clinical setting. The aim of our work was to evaluate the degree of cardiovascular damage in these young patients, using a minimally invasive technique. We then evaluated coronary flow reserve (CFR) and carotid intima-media thickness (IMT) in 25 patients (13 males, median age 23.7 years). Methods. Coronary flow velocity on the left anterior descending coronary artery was assessed by transthoracic echocardiography, before and after dipyridamole, after standard echocardiography. CFR was compared with that of a small control group (n ¼ 16; median age 25 yrs). Results. In this relatively young sample, mean CFR was 2.8 � 0.6 (median 2.75), and half of the patients had reduced coronary reserve (P ¼ 0.01). Mean IMT (0.48 � 0.08 mm) was only slightly, though significantly larger compared with the reference standard (P < 0.05) but was significantly thinner in normotensive than in hypertensive patients (0.42 � 0.06 vs 0.49 � 0.05 mm, P < 0.05). The time on dialysis prior to transplantation, hypertension and age at the time of CFR evaluation affect CFR. IMT did not correlate with CFR. Conclusions: CFR and IMT abnormalities are common in young transplant recipients, in spite of the fact that our paediatric population has much less of the atherosclerotic ‘legacy’ common to adult patients.
