RESUMO

An elderly patient with head injury was registered to the emergency room. Because the patient arrived to the hospital unconscious, her cranial, cerebrovascular, and cardiac function was studied. The cardiac function measurements were (i) heart rate, (ii) blood pressure, (iii) oxygen saturation level, (iv) electrocardiogram (ECG), (v) coronary angiogram, (vi) chest computerized tomography (CT), and (vii) echocardiogram. The head damage was studied by cerebral CT and magnetic resonance imaging (MRI). The serum ischemia and inflammatory biomarkers were analysed. For the immediate treatment, the patient received cardiovascular system supporting medication. The cardiac diagnostic results were (i) the ECG suggested an elevation in the left ventricular systolic function, (ii) the blood test showed neutrophilia, increased creatine and increased troponin I kinase values, and (iii) the coronary angiogram and ECG analysis demonstrated a lack of a myocardial infarction but identified apical akinesia. The patient did not have previous symptoms of cardiovascular disease. The brain imaging demonstrated (iv) an acute ischemia in the left occipital area and (v) increased intracranial pressure. Brain MRI indicated (vi) aqueductal stenosis and (vii) multiple gliomatotic foci demonstrating hydrocephalus caused by gliomatosis cerebri. A chest CT indicated (viii) chronic obstructive pulmonary disease (COPD). One week later, the patient died because of cardiac arrest. The diagnosis was Takotsubo syndrome enforced by gliomatosis cerebri and COPD. To our knowledge, this is the first reported case in which the cardiac dysfunction of the patient is associated with gliomatosis cerebri-derived hydrocephalus and increased intracranial pressure that together with COPD may have enhanced the negative clinical outcome.

RESUMO

Anthracyclines are widely used in anticancer protocols, but can induce cardiotoxicity by mechanisms that mainly involve oxidative damage and mitochondrial dysfunction. Radiotherapy (RT) can also impair cardiac function by promoting myocardial fibrosis, microvascular damage, and decreased density of myocardial capillaries. Hence, we aim at investigating prospectively whether RT impacts heart function in lymphoma patients who had been already treated with anthracyclines. Twenty-nine consecutive patients with Hodgkin or non-Hodgkin lymphomas underwent echocardiography at baseline (before antineoplastic treatments), and then every 2 months, until 6 months after treatment completion. Echo evaluation included standard two-dimensional and speckle tracking. Twenty-two patients treated with anthracycline-based regimens were eligible. Out of the 22 patients, 8 received chemotherapy (CT) only (subgroup 1), while 14 underwent RT after CT [subgroup 2 (S2)]. At the end of CT, ejection fraction was significantly reduced in the whole population. At 6 months after completion of therapies, E/E' increased and global longitudinal strain was compromised in S2, suggesting additional damage induced by RT after CT. On the basis of the data from our small prospective study, we can hypothesize that in lymphoma patients, anthracyclines can worsen cardiac function, and RT may have an additional unfavorable myocardial impact.

RESUMO

BACKGROUND AND AIM: Systemic lupus erythematosus (SLE) is associated with increased risk of cardiovascular disease (CVD). Among many mechanisms, accelerated atherosclerosis, endothelial dysfunction, and hypercoagulability play a main role. Here, we investigate whether inflammatory, serological and clinical markers of SLE determine and correlate with arterial stiffness in SLE patients. MATERIALS AND METHODS: Routine blood samples, inflammatory mediators, specific antibodies, and 24 h proteinuria were measured in 43 SLE patients and 43 age and sex-matched controls using routine laboratory assays. We also assessed arterial stiffness by measuring radial artery applanation tonometry-derived augmentation index (AI), normalized AI (AIx@75), aortic pulse pressure, central systolic, diastolic and peripheral blood pressure. RESULTS: SLE patients showed a significantly greater arterial stiffness vs. controls, as demonstrated by the significantly higher AIx@75 and aortic pulse pressure. Interestingly, regression analysis showed that age, systolic pulse pressure, inflammatory markers (erythrocyte sedimentation rate and C-reactive protein), daily dose of glucocorticoids, and cumulative organ damage positively correlated with arterial stiffness. CONCLUSIONS: SLE patients show increased arterial stiffness which correlates with markers of inflammation, that is involved in early alterations in arterial walls. Applanation tonometry can be used to screen SLE patients for subclinical vascular damage to implement prevention strategies for CVD.
