RESUMEN
Aims: Myocardial injury (MINJ) in Coronavirus disease 2019 (COVID-19) identifies individuals at high mortality risk but its clinical relevance is less well established for Influenza and no comparative analyses evaluating frequency and clinical implications of MINJ among hospitalized patients with Influenza or COVID-19 are available. Methods and results: Hospitalized adults with laboratory confirmed Influenza A or B or COVID-19 underwent highly sensitive cardiac T Troponin (hs-cTnT) measurement at admission in four regional hospitals in Canton Ticino, Switzerland. MINJ was defined as hs-cTnT >14 ng/L. Clinical, laboratory and outcome data were retrospectively collected. The primary outcome was mortality up to 28 days. Cox regression models were used to assess correlations between admission diagnosis, MINJ, and mortality. Clinical correlates of MINJ in both viral diseases were also identified. MINJ occurred in 94 (65.5%) out of 145 patients hospitalized for Influenza and 216 (47.8%) out of 452 patients hospitalized for COVID-19. Advanced age and renal impairment were factors associated with MINJ in both diseases. At 28 days, 7 (4.8%) deaths occurred among Influenza and 76 deaths (16.8%) among COVID-19 patients with a hazard ratio (HR) of 3.69 [95% confidence interval (CI) 1.70-8.00]. Adjusted Cox regression models showed admission diagnosis of COVID-19 [HR 6.41 (95% CI 4.05-10.14)] and MINJ [HR 8.01 (95% CI 4.64-13.82)] to be associated with mortality. Conclusions: Myocardial injury is frequent among both viral diseases and increases the risk of death in both COVID-19 and Influenza. The absolute risk of death is considerably higher in patients admitted for COVID-19 when compared with Influenza.
RESUMEN
. Care path for non-deferred elective hospitalizations in cardiology in the Covid-19 period. INTRODUCTION: The novel coronavirus-19 (Covid-19) has rapidly resulted in a global pandemic. Our hospital had to postpone all elective admissions to increase capacity for COVID-19 patients. Therefore, a rearrangement of the elective admissions was necessary to guarantee a restart of ordinary procedures. AIM: To describe the organizational model adopted for elective procedures during the Covid-19 pandemic, to guarantee maximum safety for patients and healthcare workers. METHODS: Patients on waiting list for cardiac procedures were rearranged based on risks prioritization. Procedure of coronary angiography and cardiac devices (PM and ICD) implants or replacement took priority upon other cardiac procedures. Each patient underwent a telephone nurse triage to assess for any covid-19 symptoms. The hospital admissions were organized in accordance with health and safety measures declared by the National Institute of Health, with different paths according to the swab results. RESULTS: A total of 66 patients were contacted and 40 accepted the hospital admission (26 refused it, for fear of infection or covid-19 related family problems). No patient resulted positive to the nasal swab. CONCLUSIONS: In view of the impact on the health care system of this new pandemic, the choice of an appropriate pathway which can preserve patients' safety is essential, while guaranteeing the treatment of problems, such as cardiovascular diseases, with a high mortality rate.
