Cancer therapeutics induced cardiotoxicity has emerged as an important factor of long-term adverse cardiovascular outcomes in survivors of various malignant diseases. Early detection of myocardial injury in the setting of cancer treatment is important for the initiation of targeted cardioprotective therapy, in order to prevent irreversible cardiac dysfunction and heart failure, while not withholding a potentially life-saving cancer therapy. Cardiac imaging techniques including echocardiography, cardiac magnetic resonance, and nuclear cardiac imaging are the main tools for the identification of cardiotoxicity. There is also growing evidence for the detection of subclinical cardiac dysfunction in cancer patients by speckle tracking echocardiography. In this review article, we focus on current and emerging data regarding the role of cardiac imaging for the detection of changes in myocardial function related with cancer treatment in clinical practice.

AimsRemote ischemic conditioning (RIC) alleviates ischemia–reperfusion injury via several pathways, including micro-RNAs (miRs) expression and oxidative stress modulation. We investigated the effects of RIC on endothelial glycocalyx, arterial stiffness, LV remodelling, and the underlying mediators within the vasculature as a target for protection.Methods and resultsWe block-randomised 270 patients within 48 h of STEMI post-PCI to either one or two cycles of bilateral brachial cuff inflation, and a control group without RIC. We measured: (a) the perfusion boundary region (PBR) of the sublingual arterial microvessels to assess glycocalyx integrity; (b) the carotid-femoral pulse wave velocity (PWV); (c) miR-144,-150,-21,-208, nitrate-nitrite (NOx) and malondialdehyde (MDA) plasma levels at baseline (T0) and 40 min after RIC onset (T3); and (d) LV volumes at baseline and after one year. Compared to baseline, there was a greater PBR and PWV decrease, miR-144 and NOx levels increase (p < 0.05) at T3 following single- than double-cycle inflation (PBR:ΔT0–T3 = 0.249 ± 0.033 vs 0.126 ± 0.034 μm, p = 0.03 and PWV:0.4 ± 0.21 vs −1.02 ± 0.24 m/s, p = 0.03). Increased miR-150,-21,-208 (p < 0.05) and reduced MDA was observed after both protocols. Increased miR-144 was related to PWV reduction (r = 0.763, p < 0.001) after the first-cycle inflation in both protocols. After one year, single-cycle RIC was associated with LV end-systolic volume reduction (LVESV) > 15% (odds-ratio of 3.75, p = 0.029). MiR-144 and PWV changes post-RIC were interrelated and associated with LVESV reduction at follow-up (r = 0.40 and 0.37, p < 0.05), in the single-cycle RIC.ConclusionRIC evokes “vascular conditioning” likely by upregulation of cardio-protective microRNAs, NOx production, and oxidative stress reduction, facilitating reverse LV remodelling.Clinical Trial Registrationhttp://www.clinicaltrials.gov.

Takotsubo syndrome (TTS) is an acute and mostly reversible cardiomyopathy that mimics an acute coronary syndrome with left ventricular (LV) systolic dysfunction without relevant obstructive coronary artery disease. Its prevalence is probably underestimated and reaches 1.2–2% in patients with acute coronary syndrome undergoing coronary catheterization. Although supraphysiological epinephrine levels have been associated with TTS, the detailed pathophysiology is incompletely understood. Chest pain is the most common clinical presentation; however, cardiac decompensation, cardiogenic shock, and sudden cardiac death due to ventricular fibrillation may also be the first clinical manifestations. Patients are mostly postmenopausal women, in whom the condition is commonly associated with emotional triggers; however, men have a higher prevalence of TTS being associated with physical triggers, which has a worse prognosis compared with TTS associated with emotional triggers. As a diagnosis of exclusion, TTS has no single definitive diagnostic test. According to the distribution of LV wall motion abnormalities, various morphological subtypes have been identified. The final diagnosis depends on cardiac imaging with left ventricular angiography during acute heart catheterization, as well as on echocardiography and cardiac magnetic resonance. Most patients recover completely, albeit several factors have been associated with worse prognosis. Management is based on observational data, while randomized multicenter studies are still lacking. This review provides a general overview of TTS and focuses on the hypothesized pathophysiology, and especially on current practices in diagnosis, prognosis, and treatment.

The phosphodiesterase 4 inhibitor apremilast is used for the treatment of psoriasis. We investigated the effects of apremilast on endothelial glycocalyx, vascular and left ventricular (LV) myocardial function in psoriasis. One hundred and fifty psoriatic patients were randomized to apremilast (n = 50), anti-tumor necrosis factor-α (etanercept; n = 50), or cyclosporine (n = 50). At baseline and 4 months post-treatment, we measured: (1) Perfused boundary region (PBR), a marker of glycocalyx integrity, in sublingual microvessels with diameter 5–25 μm using a Sidestream Dark Field camera (GlycoCheck). Increased PBR indicates damaged glycocalyx. Functional microvascular density, an index of microvascular perfusion, was also measured. (2) Pulse wave velocity (PWV-Complior) and (3) LV global longitudinal strain (GLS) using speckle-tracking echocardiography. Compared with baseline, PBR5–25 μm decreased only after apremilast (−12% at 4 months, p < 0.05) whereas no significant changes in PBR5–25 μm were observed after etanercept or cyclosporine treatment. Compared with etanercept and cyclosporine, apremilast resulted in a greater increase of functional microvascular density (+14% versus +1% versus −1%) and in a higher reduction of PWV. Apremilast showed a greater increase of GLS (+13.5% versus +7% versus +2%) than etanercept and cyclosporine (p < 0.05). In conclusion, apremilast restores glycocalyx integrity and confers a greater improvement of vascular and myocardial function compared with etanercept or cyclosporine after 4 months.

Hypertrophic cardiomyopathy (HCM) represents a phenotype of left ventricular hypertrophy unexplained by abnormal loading conditions. The definition is based on clinical criteria; however, there are numerous underlying etiologic factors. The MOGE(S) classification provides a standardized approach for multimodal characterization of HCM. HCM is associated with increased morbidity and mortality, and especially the assessment of the risk of sudden cardiac death is of paramount importance. In this review, we summarize essential knowledge and recently published data on clinical presentation, diagnosis, genetic analyses, differential diagnosis, prognosis, and treatment options that are necessary for understanding and management of HCM.

Psoriatic disease is associated with vascular and myocardial dysfunction. We aimed to evaluate endothelial glycocalyx barrier properties and microvascular perfusion in psoriatic patients, as well as their correlation with carotid intima-media thickness (cIMT) and markers of left ventricular (LV) myocardial deformation. We examined 297 psoriatic patients and 150 controls, adjusted for age, sex, and atherosclerotic risk factors. The severity of psoriatic disease was estimated using the psoriasis area and severity index (PASI). Perfused boundary region (PBR), a marker of glycocalyx barrier function, was measured non-invasively in sublingual microvessels with a diameter 5–25 μm using Sidestream Dark Field camera (Microscan, GlycoCheck). Increased PBR indicates reduced glycocalyx thickness. Indexes of microvascular perfusion, including red blood cells filling (RBCF) and functional microvascular density, were also calculated. We measured cIMT, coronary flow reserve (CFR) and markers of myocardial deformation by speckle-tracking imaging, namely global longitudinal strain (GLS) and percentage changes between peak twisting and untwisting at mitral valve opening (%dpTw-UtwMVO). Compared to controls, psoriatic patients had higher PBR5-25μm (2.13 ± 0.29μm versus 1.78 ± 0.25μm, p < 0.001) and lower RBCF and functional microvascular density (p < 0.001). Increased PASI was associated with elevated PBR and more impaired cIMT and GLS (p < 0.05). There was an inverse association of PBR with RBCF and functional microvascular density (p < 0.001). In psoriatic population, increased PBR was related to increased cIMT, reduced CFR, impaired GLS and decreased %dpTw-UtwMVO (p < 0.001). Glycocalyx thickness is reduced in psoriatic patients, which in turn impairs microvascular perfusion, and is associated with carotid IMT and impaired coronary and myocardial function.Clinical Trial Registration—URL: http://www.clinicaltrials.gov.

BackgroundAnakinra, an interleukin-1 receptor antagonist and tocilizumab, an interleukin-6 receptor blocker, are used for the treatment of rheumatoid arthritis. We investigated the differential effects of anakinra and tocilizumab on myocardial and vascular function in an atherosclerosis model of patients with rheumatoid arthritis.Methods120 patients with rheumatoid arthritis were randomized to anakinra (n = 40), tocilizumab (n = 40) or prednisolone (n = 40) for 3 months. Primary outcome measure was the change of left ventricular longitudinal strain after 3 months of treatment. Additionally, we measured coronary flow reserve, flow-mediated dilatation of the brachial artery, carotid-femoral pulse wave velocity, malondialdehyde and protein carbonyls as oxidative stress markers and C-reactive protein blood levels at baseline and post-treatment.ResultsAt baseline, patients among the three treatment arms had similar age, sex, disease activity score and atherosclerotic risk factors. Compared with baseline, all patients had improved longitudinal strain (− 16% vs. − 17.8%), coronary flow reserve (2.56 vs. 2.9), malondialdehyde (2.0 vs. 1.5 µM/L), protein carbonyls (0.0132 vs. 0.0115 nmol/mg), and C-reactive protein post-treatment. In all patients, the percent decrease of malondialdehyde was correlated with percent increase of longitudinal strain (p < 0.001). Compared with tocilizumab and prednisolone, anakinra treatment resulted in a greater improvement of longitudinal strain (18.7% vs. 9.7% vs. 6%) and coronary flow reserve (29% vs. 13% vs. 1%), while pulse wave velocity and brachial blood pressure were improved only after tocilizumab treatment (11 ± 3 vs. 10.3 ± 2 m/s p < 0.05 for all comparisons).ConclusionsAnakinra is associated with an improvement in cardiac function and tocilizumab with improvement in vascular function.Clinical Trial RegistrationURL: https://http://www.clinicaltrials.gov.

Patients with active cancer are at high risk of recurrent venous thromboembolism (VTE). Usual treatment includes low molecular weight heparin (LMWH), while vitamin K antagonists (VKAs) have also been used as substitutes for LMWH. Direct oral anticoagulants (DOACs) are considered a beneficial alternative to the usual treatment but are accompanied by an increased rate of bleeding compared to LMWH. We conducted a meta-analysis to evaluate the benefits and harms under a common denomination, namely the net clinical benefit (NCB), between DOACs and usual anticoagulation. The primary outcome was NCB-1, defined as non-fatal VTE, major non-fatal bleedings, and all-cause mortality). Co-primary outcomes were 1) NCB-2 (i.e., NCB-1 and clinically relevant non-major bleedings) and 2) NCB-3 (i.e., fatal or non-fatal VTE and major bleedings). A random-effects model was used to calculate outcome risk ratios and 95% confidence intervals (CI). Prospective Register of Systematic Reviews identification number CRD42021284238. We selected 8 studies (n = 4,4461 patients; mean follow-up, 6 months). The NCB-1 and -2 were not different between DOACs and usual anticoagulation, while the NCB-3 showed a reduction of 28% (95% CI, 10–42%), favoring DOACs. Recurrent VTE was reduced by 40% (95% CI, 25–53%) with DOACs than the usual treatment. Different bleeding outcomes and all-cause mortality were not different between treatments. All primary outcomes did not differ between DOACs and LMWH, while NCB-2 and NCB-3 were reduced with DOACs than VKAs. The NCB of DOACs was similar or more favorable to usual anticoagulation in patients with active cancer due to a substantial reduction of VTE and no bleeding excess.
