ABSTRACT
RESUMEN Introducción: Se ha descrito que la infección por COVID-19 se asocia a complicaciones cardiovasculares en pacientes hospitalizados en 7-28%de los casos, con diagnóstico basado en elevación de biomarcadores. La afección cardiaca subclínica post COVID-19 en pacientes ambulatorios representa una preocupación creciente, así como las secuelas cardiovasculares a mediano y largo plazo. El objetivo del presente trabajo fue determinar la utilidad de la detección de compromiso cardiovascular en pacientes post COVID-19 ambulatorios, y su asociación con síntomas y factores de riesgo. Material y métodos: Se incluyeron 668 pacientes de manera prospectiva, >18 años entre septiembre de 2020 y marzo de 2021. Debían tener polimerasa de transcriptasa inversa (PCR) positiva en una muestra del tracto respiratorio positiva para COVID-19, y se les realizó evaluación con examen físico, electrocardiograma (ECG) y eco Doppler cardíaco. A quienes presentaban síntomas de riesgo o anomalías en el ECG o el eco Doppler, se les solicitó resonancia cardíaca (RMC) con contraste endovenoso. Resultados: La edad media fue de 42,9 ± 14,9 años; el 56,9% fueron mujeres. El 12,9% eran hipertensos, el 4,3% diabéticos y el 6,9% obesos. El 57,6% no tenía factores de riesgo cardiovascular y solo el 4,2% contaba con antecedentes cardiovasculares. El 73,2% presentó enfermedad leve, un 16,3% requirió internación y el 1,05% asistencia ventilatoria mecánica. Solo 5 pacientes tuvieron diagnóstico por RMC de miocarditis, y tanto el derrame pericárdico como la presencia de trastornos de la repolarización se asociaron significativamente con la misma (p <0,0001). Conclusiones: La presencia de alteraciones en el ECG o el eco Doppler cardíaco en nuestra cohorte fue infrecuente. Se diagnosticaron 5 casos de miocarditis viral con clínica compatible y confirmación por RMC.
ABSTRACT Introduction: COVID-19 infection has been associated with cardiovascular complications in 7-28% of hospitalized patients, with the diagnosis based on biomarkers elevation. Subclinical cardiac involvement in outpatients recovered from COVID-19 represents a growing concern, as well as mid- or long-term cardiovascular effects. Objective: The aim of the present study was to determine the usefulness of detecting cardiovascular involvement in outpatients recovered from COVID-19, and its association with symptoms and risk factors. Methods: Between September 2020 and March 2021, 668 patients >18 years were prospectively included. All the patients had to have COVID-19 confirmed diagnosis by a positive reverse transcription-polymerase chain reaction (RT-PCR) test in a respiratory tract sample COVID-19. They were evaluated with physical examination, electrocardiogram (ECG) and Doppler echocardiography. Patients with symptoms suggestive of risk or abnormal findings on ECG or echocardiogram underwent cardiac magnetic resonance imaging (CMRI) with gadolinium-based contrast agent. Results: Mean age was 42.9 ± 14.9 years and 56.9% were women; 12.9% were hypertensive, 4.3% were diabetic and 6.9% obese. Overall, 57.6% had no cardiovascular risk factors and only 4.2% had a history of cardiovascular disease. The disease was mild in 73.2%; 16.3% required hospitalization and 1.05% needed mechanical ventilation. Only 5 patients had myocarditis diagnosed by CMRI, and both pericardial effusion and abnormal repolarization were significantly associated with myocarditis (p < 0.0001). Conclusions: Abnormal ECG or echocardiographic findings were uncommon in our cohort. The diagnosis of viral myocarditis was made in 5 cases with clinical signs and symptoms, and was confirmed by CMRI.
ABSTRACT
INTRODUCTION/OBJECTIVES: Cardiovascular risk management of patients with systemic lupus erythematosus (SLE) is medically relevant. The objectives were to estimate the cardiovascular risk by different strategies in patients with SLE, analyzing which proportion of patients would be candidates to receive statin therapy, and identify how many patients with statin indication received such drugs. METHOD: A cross-sectional study was performed from a secondary database. Following the recommendations of National Institute for Health and Care Excellence (NICE) guidelines and the Argentine Consensus, the QRISK-3 and the adjusted Framingham (multiplying factor × 2) scores were calculated in primary prevention subjects. The indications for statin therapy according to these recommendations were analyzed. RESULTS: In total, 110 patients were included. Regarding patients without previous cardiovascular history, the median adjusted Framingham score was 12.8% (4.1-21.9), and 45.2%, 22.6%, and 32.2% of them were classified at low, moderate, or high risk. The median QRISK-3 score was 6.0% (2.1-14.1) and 42.1% of subjects were classified "at risk". Only 60% of subjects in secondary prevention received statins, although no patient received the recommended doses. Analyzing patients in primary prevention who did not receive statins (87%), 43.4% and 45.2% of the patients were eligible for statin therapy according to NICE guidelines and Argentine Consensus, respectively. CONCLUSIONS: Our findings showed that a large proportion of patients with SLE have a considerable cardiovascular risk and many of them would be eligible for statin therapy. However, the statin use observed was low.Key Points⢠A large proportion of patients with lupus have a considerable cardiovascular risk, explained in part by dyslipidemia.⢠Many patients with SLE would be eligible for statin therapy according to risk stratification based on conventional risk factors.⢠The use of statins in this population is inadequate.
