Association of calcium channel blocker use with clinical outcome of COVID-19: A meta-analysis.

Aims: This meta-analysis aims to analyze the association of calcium channel blocker (CCB) use with COVID-19 clinical outcomes.

Methods: PubMed, ProQuest, Science Direct, Scopus, and medRxiv databases were searched systematically in a limited period. The primary outcome was mortality.

Evaluation of heart rate variability using 24-hour Holter electrocardiography in hypertensive patients.

Background: Hypertension (HTN) remains a serious risk factor for cardiovascular mortality across the world. Hypertensive state has been shown to be associated with autonomic nervous function. This study aimed to explore the association between autonomic nervous impairment assessed by heart rate variability (HRV) and HTN.

Elevated fibrinogen and fibrin degradation product are associated with poor outcome in COVID-19 patients: A meta-analysis.

Introduction: COVID-19 is a systemic infection with a significant impact on coagulation which manifests in thromboembolism. There is an unknown relationship of which coagulation profile parameter at presentation has an association with poor outcome in COVID-19.

Objective: This meta-analysis aimed to determine the relationship between fibrinogen and FDP with poor outcome in COVID-19 patients.

Relationship of D-dimer with severity and mortality in SARS-CoV-2 patients : A meta-analysis.

Introduction: The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a pandemic. Many studies have shown that several laboratory parameters are related to disease severity and mortality in SARS-CoV-2 cases. This meta-analysis aimed to determine the relationship of a prognostic factor, D-dimer, with disease severity, need for intensive care unit (ICU) care, and mortality in SARS-CoV-2 patients.
