RESUMO

INTRODUCTION: Compared with previous waves of the coronavirus disease 2019 (COVID-19) pandemic in Hong Kong, the third wave involved a greater number of frail older patients. Because local healthcare policy required hospitalisation for all older adults with COVID-19, we aimed to investigate the clinical course and outcomes in such patients. METHODS: This retrospective observational study included all patients aged ≥65 years who were admitted to Tuen Mun Hospital for management of COVID-19 between 1 July 2020 and 31 August 2020. We reviewed baseline characteristics, clinical presentation, laboratory results, complications, and outcomes. We also investigated the associations of age and Clinical Frailty Scale (CFS) score with in-patient mortality. RESULTS: In total, 101 patients were included (median age, 73 years); 52.5% were men and 85% had at least co-morbid chronic disease. The most common symptoms were fever (80.2%) and cough (63.4%). Fifty-two patients (51.5%) developed hypoxia, generally on day 8 (interquartile range, 5-11) after symptom onset. Of the 16 patients who required intensive care unit support, 13 required mechanical ventilation. The overall mortality rate was 16.8%. Patients aged 65-69, 70-79, 80-89, and ≥90 years had mortality rates of 9.1%, 10%, 30%, and 25%, respectively. Patients with CFS scores of 1-2, 3-4, 5-6, and ≥7 had mortality rates of 5.7%, 14.7%, 23.5%, and 40%, respectively. A linear relationship was confirmed between the two mortality trends. CONCLUSION: Clinical deterioration was common in older patients with COVID-19; their overall mortality rate was 16.8%. Mortality increased linearly with both age and CFS score.

RESUMO

As a clinical entity the Brugada syndrome has existed since 1992 and has been associated with a high risk of sudden cardiac death predominately in younger males. Patients can present with symptoms (ie syncope, palpitations, aborted sudden cardiac death) and asymptomatically. Its three characteristic electrocardiographic patterns can occur both spontaneously or after provocation with sodium channel-blocking agents. Risk stratification and the need for treatment depend on the patient's symptoms, electrocardiography, family history, and electrophysiological inducibility to discern if treatment by implantable cardioverter defibrillator, the only effective treatment to date, is appropriate. This review focuses on Brugada syndrome and various aspects of the disease including proposed mechanisms, epidemiology, clinical presentations, genetics, diagnosis, risk stratification, and treatment options.
