Background: Ferritin, a crucial element for iron homeostasis, is associated with chronic diseases characterized by subclinical inflammation such as essential arterial hypertension and type 2 diabetes mellitus (T2DM), showing a prognostic value in different clinical settings. We investigated whether ferritin is associated with arterial stiffness (AS), an early indicator of atherosclerosis, and if it could act as effect modifier on the relationship between inflammation and AS in hypertensive patients with different glucose tolerance. Methods: We enrolled 462 newly diagnosed untreated hypertensive (HT) patients. All subjects underwent an oral glucose tolerance test. Insulin sensitivity was assessed by MATSUDA index and ferritin levels were estimated by immunoradiometric assay. AS was defined by carotid-femoral pulse wave velocity (PWV). Results: Out of 462 patients, 271 showed normal glucose tolerance (HT/NGT), 146 impaired glucose tolerance (HT/ IGT) and 45 were diabetic (HT/T2DM). Iron levels significantly decreased and transferrin and ferritin significantly increased from the first to the third group. PWV values were significantly higher in HT/IGT and HT/T2DM patients. PWV was related directly with ferritin, high sensitivity C reactive protein (hs-CRP), transferrin, and inversely with MATSUDA index. Ferritin resulted the strongest determinant of PWV explaining a 14.9% of its variation; moreover it was a strong modifier of the relationship between hs-CRP and PWV. The estimated augmentation in PWV portended by a fixed increase in hs-CRP, was higher across increasing values of ferritin. Conclusion: Ferritin represents an independent risk factor of arterial stiffness in our study population and a strong effect modifier on the relationship between inflammation and PWV. However, further studies are needed to fully elucidate the potential role of this biomarker in human atherosclerosis.
Objective transcatheter tricuspid valve repair (TTVR) has recently become available as a treatment option for patients with symptomatic significant tricuspid regurgitation (TR) not eligible for tricuspid valve surgery. In the absence of a single reliable measure of the RV systolic function, a number of surrogate echocardiographic parameters have been proposed for clinical use (tricuspid annular plane systolic excursion (TAPSE), RV fractional area change (FAC), peak S wave velocity of the lateral tricuspid annulus by tissue Doppler imaging (S’ RV-TDI) and RV 2D-FWS. At present, TTVR is not recommended in patients with severe PH and poor RV function, but exact cut-offs when TTVR should be rejected are lacking. Aim of this study was to assess RV function before and after Triclip implantation. Materials and methods from June 2021 to June 2022 clinical and echocardiographic data of 8 patients with TR who underwent TTVR intervention in our division were evaluated for RV function. TAPSE, FAC, S’RV-TDI, RV GS and RV FWS at baseline and 1 month of follow up were assessed. Continuous variables are presented as mean ± standard deviation (SD). Categorical variables were presented as frequencies and percentages. Results the mean values of RV function assessed before and after Triclip implantation were respectively (18,75 mm± 4,04 vs 18,38 mm ± 3,34) for TAPSE, (10,50 cm/sec± 2,33 vs 10,38 cm/sec ± 1,19) for S’ RV-TDI, (38% ± 0,05 vs 37% ± 0,04) for FAC, and (-17% ± 0,03 vs -19% ± 0,02) for RV FWS. The number of patients that show at baseline RV dysfunction, according to the cut-offs indicated from guidelines, were 4 for TAPSE; 3 S’ RV-TDI; 1 for FAC and 7 for RV 2D-FWS. At 1 month of follow-up, patients with ventricular dysfunction were respectively 3,2,2,4. Conclusions in the presence of significant TR, the accurate assessment of RV function becomes even more challenging as a result of the load and angle dependency of TAPSE, RVFAC. Significant TR results in a reduction in RV afterload, which may preserve the aforementioned markers of RV function even when contractility is impaired. Probably RV 2D-STE is less angle and load dependent than traditional RV function indices and less confounded by RV geometry and passive motion.
Introduction The heart is a rare site of tumor metastasis. Although rarely, cardiac metastases may be secondary to a primary intra-abdominal tumor. Aim we report the case of a 60-years-old woman, ante-mortem finding of an isolated cardiac metastasis from cervical carcinoma presented as ACS-NSTE, who was evaluated in our Division of Cardiology. Materials and methods electrocardiogram, transthoracic echocardiography, angioTC, cardiac surgery and histopathologic analysis were performed. Results electrocardiogram showed incomplete right branch block with diffuse negative T waves. On the echocardiogram evidence of a voluminous hypo-isoechoic formation almost completely occupying the cavity of the right ventricule (RV) which appeared dilated and dysfunctional; D-shape aspect of the left ventricule as from the overload of the right sections and with moderate pericardial effusion, mildly reduced ejection fraction (EF50%Q). An urgent Angio-CT was performed and revealed a voluminous solid neoformation with inhomogeneous content and progressive contrast enhancement in the right ventricule. Following admission, the patient's haemodynamic status gradually worsened. Therefore, urgent cardiac surgery was performed. After drainage of abundant serum/haematic effusion, probably neoplastic infiltration of RV was seen. Therefore, given the extension it was decided to perform only multiple biopsies. Histopathological examination revealed moderately differentiated squamous cell carcinoma, as from metastasis from K. cervix. Conclusions there is no standardized therapy for the treatment of cardiac metastases, it is necessary to evaluate on a case-by-case basis. The most important prognostic factors are the obstructive effect of the intracardiac mass and the extent of any pericardial effusion. In fact, they can adversely affect hemodynamic stability.
An 87-year-old male patient with worsening dyspnea was admitted to our institution. The patient had a history of acute myocardial infarction treated with coronary stenting of the left descending artery (LAD), diagonal (Diag), right coronary artery (RCA), and chronic kidney disease. For acute pulmonary edema, the patient was admitted to our cardiac intensive care unit and rapidly treated with non-invasive positive-pressure ventilation with continuous positive airway pressure (C-PAP), IV high dosage diuretic therapy, inotropes, and vasoactive agents. Chest X-ray revealed cardiomegaly (cardiothoracic ratio, 56%) and pulmonary congestion. Electrocardiogram revealed sinus tachycardia and diffuse ST-segment abnormalities. An echocardiogram demonstrated left ventricular apical akinesia, with a left ventricular ejection fraction (LVEF) of 25% and severe mitral regurgitation. Blood tests revealed very high levels of NT-pro-brain natriuretic peptide (NT-proBNP) (>30000 pg/ml) and myocardial necrosis markers (hs-Trop 5055 ng/l; CK-MB 72 ng/ml). After 24 hours, the patient was placed on intra-aortic balloon pump (IABP) support to further hemodynamic support through the right femoral artery, nonetheless, he showed no improvement in symptoms or urine output. Because of a state of hypoxemic and hypercapnic respiratory failure, non-invasive ventilation (NIV) was given to the patient with a gradual improvement in blood gas analysis. The optimization of diuretic therapy allowed to treat the state of acute oliguric kidney disease, avoiding dialytic treatment. After 48 hours, because of a new worsening in hemodynamic state, we decided for a percutaneous left ventricular assist device (Impella CP, Denver, Massachusetts, USA). After placing the Impella device, coronary angiography was performed, showing critical stenosis of the left main (LM), involving the origin of the left anterior descending artery and a collateralized chronic occlusion of the circumflex artery and the LAD, after the origin of a large first diagonal branch. Because of the high procedural risk, we decided to perform only percutaneous coronary intervention and stent implantation of LM. After 3 days his symptoms improved, the required dose of inotropic agents and furosemide decreased and Impella was removed. After 12 days the patient was admitted to the cardiological ward and discharged after 21 days because of a urinary infection requiring antibiotic therapy. The management of acute heart failure in very old patients is challenging, limiting in many cases the use of invasive procedures such as coronary angiography or left ventricular assist devices. In this case, although the patient presented a very high-risk profile considering age and comorbidities, the use of Impella resulted to be safe and guaranteed hemodynamic support during the procedure of revascularization and in the immediate post-operative phase.
