RESUMO
Resumo Fundamento A nova doença por coronavírus (COVID-19) pode levar a uma enfermidade grave e causar a morte. Sabe-se que a COVID-19 afeta o sistema cardiovascular. A detecção precoce da progressão para um estágio grave da doença que afeta o sistema cardiovascular pode desempenhar um papel crítico no tratamento da COVID-19. Objetivos Explorar a possível relação entre a pneumonia por COVID-19 e os achados de strain do ventrículo direito no eletrocardiograma (ECG). Métodos Foi realizado um estudo retrospectivo de 141 pacientes hospitalizados com COVID-19. A correlação de Spearman e as análises de regressão logística foram aplicadas para avaliar as relações entre as manifestações de strain ventricular direito na ECG e os níveis de biomarcadores e outros achados laboratoriais e de imagem do tórax. O nível de significância foi considerado estabelecido como p < 0,05. Resultados Os sinais de ECG de estresse ventricular direito foram significativamente mais frequentes e os níveis de fibrinogênio, PCR e ferritina foram significativamente mais elevados em pacientes com COVID-19 com níveis elevados de hs-cTnI, procalcitonina e dímero-D. A análise univariada mostrou que existem relações significativas entre a presença de pneumonia bilateral, a maioria dos sinais eletrocardiográficos de strain ventricular direito e lesão cardíaca e biomarcadores inflamatórios e trombóticos. A análise multivariada revelou que o supradesnivelamento do segmento ST em V1 e padrão S1Q3T3 são preditores independentes de lesão cardíaca ( odds ratio =0,23; IC95%, 0,06 a 0,90; p=0,035) e níveis elevados de procalcitonina ( odds ratio =0,19; IC 95%, 0,06 a 0,62; p=0,006), respectivamente. Conclusão Os achados do presente estudo sugerem que a dano cardíaco direito é prevalente na COVID-19. Além disso, nosso estudo demonstra o valor clínico do ECG na avaliação e monitoramento de pacientes com pneumonia por COVID-19.
Abstract Background The novel coronavirus disease (COVID-19) may lead to severe disease that can cause death. COVID-19 is known to affect the cardiovascular system. Early detection of the progression to the severe disease stage that affects the cardiovascular system may play a critical role in the treatment of COVID-19. Objectives To explore the possible relationship between the COVID-19 pneumonia and right ventricular strain findings on electrocardiography (ECG). Methods We conducted a retrospective study of 141 hospitalized patients with COVID-19. Spearman's correlation and logistic regression analyses were applied to assess relationships between ECG manifestations of right ventricular strain and levels of biomarkers and other laboratory and chest imaging findings. The significance level was considered as < 0.05. Results The ECG signs of right ventricular stress were significantly more frequent and the levels of fibrinogen, CRP, and ferritin were significantly higher in COVID-19 patients with elevated levels of hs-cTnI, procalcitonin and D-dimer. The univariate analysis showed there are significant relations between the presence of bilateral pneumonia, most of the ECG signs of right ventricular strain and cardiac injury and inflammatory and thrombotic biomarkers. The multivariate analysis revealed that ST-segment elevation in V1and the S1Q3T3pattern are independent predictors of cardiac damage (odds ratio=0.23; 95% CI, 0.06 to 0.90; p=0.035) and elevated procalcitonin levels (odds ratio=0.19; 95% CI, 0.06 to 0.62; p=0.006), respectively. Conclusion The findings of the present study suggest that right heart damage is prevalent in COVID-19. In addition, our study shows the clinical value of ECG in evaluating and monitoring the patients with COVID-19 pneumonia.

BACKGROUND: Recent studies showed a high frequency of low bone mineral density (BMD) in HIV-infected patients and no reports have been issued in Turkey. Our aim was to evaluate BMD and risk factors for osteopenia/osteoporosis in HIV-infected patients that attended an outpatient clinic in Istanbul, Turkey. METHOD: In order to determine the prevalence of BMD, 126 HIV-infected patients had been studied with dual energy X-ray absorptiometry (DEXA). The association between BMD and age, gender, body mass index (BMI), habits, 25(OH)vitamin D, HIV RNA, CD4 lymphocyte nadir, using and duration of highly active antiretroviral treatment (HAART) were investigated by using multivariate analysis. RESULTS: Median age was 40.1 years (range, 20-70); 84% were male; 35.7% patients had AIDS, 63.5% were treated with HAART. Osteopenia and osteoporosis were diagnosed in 53.9% and 23.8%, respectively. Mean plasma HIV RNA was 5.2 (SD 1.0) log10 copies/mL and CD4 lymphocyte nadir was 313.8 (SD 226.2)/mm(3). Factors associated with bone loss were high viral load (p=0.034), using (p=0.033) and duration of HAART (p=0.008). No correlation had been seen between sex and osteopenia/osteoporosis (p=0.794). However, males showed higher rates of osteoporosis than females (p=0.042). CONCLUSIONS: Our results show a very high prevalence of bone mass reduction in Turkish HIV-infected patients. This study supports the importance of both HIV and antiretroviral therapy in low BMD.
