Application of machine learning to predict the occurrence of arrhythmia after acute myocardial infarction.

Background: Early identification of the occurrence of arrhythmia in patients with acute myocardial infarction plays an essential role in clinical decision-making. The present study attempted to use machine learning (ML) methods to build predictive models of arrhythmia after acute myocardial infarction (AMI).

Methods: A total of 2084 patients with acute myocardial infarction were enrolled in this study.

Effects of ACEI and ARB on COVID-19 patients: A meta-analysis.

Background: The clinical use of angiotensin-converting enzyme inhibitors (ACEI) and angiotensin-receptor blockers (ARB) in patients with COVID-19 infection remains controversial. Therefore, we performed a meta-analysis on the effects of ACEI/ARB on disease symptoms and laboratory tests in hypertensive patients infected with COVID-19 virus and those who did not use ACEI/ARB.

Methods: We systematically searched the relevant literatures from Pubmed, Embase, EuropePMC, CNKI, and other databases during the study period of 31 December 2019 (solstice, 15 March 2020), and analyzed the differences in symptoms and laboratory tests between patients with COVID-19 and hypertension who used ACEI/ARB drugs and those who did not.

Clinical characteristics of COVID-19 with cardiac injury: a systematic review and meta-analysis.

Objectives: Cardiac injury is associated with poor prognosis of 2019 novel coronavirus disease 2019 (COVID-19), but the risk factors for cardiac injury have not been fully studied. In this study, we carried out a systematic analysis of clinical characteristics in COVID-19 patients to determine potential risk factors for cardiac injury complicated COVID-19 virus infection.

Methods: We systematically searched relevant literature published in Pubmed, Embase, Europe PMC, CNKI and other databases.

Clinical analysis of the syndrome of inappropriate antidiuretic hormone secretion after brain injury.

Objective: To study the diagnosis and treatment of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) after brain injury.

Methods: A retrospective analysis was conducted on 12 patients suffered from SIADH after brain injury. The clinical features of these patients were similar to those of common hyponatremia.
