Preoperative electrocardiogram in prediction of 90-day postoperative mortality: retrospective cohort study.

Background: There are conflicting data on the relationship between preoperative electrocardiogram and postoperative mortality. We aimed to assess the predictive value of preoperative ECG on postoperative all-cause mortality in patients undergoing non-cardiac surgery (NCS).

Methods: We retrospectively reviewed records of hospitalized patients who underwent an internal preoperative examination and subsequent NCS in the years 2015-2021.

A Simple Risk Formula for the Prediction of COVID-19 Hospital Mortality.

SARS-CoV-2 respiratory infection is associated with significant morbidity and mortality in hospitalized patients. We aimed to assess the risk factors for hospital mortality in non-vaccinated patients during the 2021 spring wave in the Czech Republic. A total of 991 patients hospitalized between January 2021 and March 2021 with a PCR-confirmed SARS-CoV-2 acute respiratory infection in two university hospitals and five rural hospitals were included in this analysis.

Mortality of hospitalized patients with COVID-19: Effects of treatment options (vitamin D, anticoagulation, isoprinosine, ivermectin) assessed by propensity score matching, retrospective analysis.

Introduction: SARS-CoV-2 respiratory infection is associated with significant morbidity and mortality, especially in hospitalized high-risk patients. We aimed to evaluate the effects of treatment options (vitamin D, anticoagulation, isoprinosine, ivermectin) on hospital mortality in non-vaccinated patients during the 2021 spring wave in the Czech Republic.

Methods: Initially, 991 patients hospitalized in the period January 1, 2021, to March 31, 2021, with PCR-confirmed SARS-CoV-2 acute respiratory infection in two university and five rural hospitals were included in the study.

[What is new in 2022 ESC guidelines on cardiovascular assessment and management of patients undergoing non‑cardiac surgery].

In 2022, the European Society of Cardiology has published updated guidelines for the cardiovascular evaluation and management of patients undergoing non-cardiac surgery. In this article we briefly summarize the most important recommendations with an emphasis on their use in everyday clinical practice - from the complex assessment of cardiovascular risk and prediction of cardiovascular complications, through the indication of basic paraclinical examinations, the importance of biomarkers, adjustments to pharmacotherapy of heart failure, adjustments to anticoagulant and antiplatelet therapy, to other specifics of individual cardiovascular and other diseases and their importance in the perioperative period. Knowledge and use of these recommendations have the potential to improve the prognosis of patients undergoing various types of surgical procedures.
