Statin Use in Relation to COVID-19 and Other Respiratory Infections: Muscle and Other Considerations.

Statins have been widely advocated for use in COVID-19 based on large favorable observational associations buttressed by theoretical expected benefits. However, past favorable associations of statins to pre-COVID-19 infection outcomes (also buttressed by theoretical benefits) were unsupported in meta-analysis of RCTs, RR = 1.00.

Platelet mitochondrial function and endogenous coenzyme Q10 levels are reduced in patients after COVID-19.

Background: After an acute treatment for coronavirus disease (COVID-19), some symptoms may persist for several weeks, for example: fatigue, headaches, muscle and joint pain, cough, loss of taste and smell, sleep and memory disturbances, depression. Many viruses manipulate mitochondrial function, but the exact mechanisms of SARS-CoV-2 virus effect remain unclear. We tested the hypothesis that SARS-CoV-2 virus may affect mitochondrial energy production and endogenous biosynthesis of coenzyme Q10 (CoQ10).

Platelet mitochondrial respiration and coenzyme Q10 could be used as new diagnostic strategy for mitochondrial dysfunction in rheumatoid diseases.

Introduction: Rheumatoid arthritis (RA) is a chronic inflammatory autoimunne disorder affecting both small and large synovial joints, leading to their destruction. Platelet biomarkers are involved in inflammation in RA patients. Increased circulating platelet counts in RA patients may contribute to platelet hyperactivity and thrombosis.

The new European guidelines for prevention of cardiovascular disease are misleading.

: The European Society of Cardiology and European Atherosclerosis Society (ESC/EAS) have recently published three major revisions of their guidelines for the management of chronic heart disease, blood lipids, and diabetes. : We have scrutinized these guidelines in detail and found that the authors have ignored many studies that are in conflict with their conclusions and recommendations. : The authors of the guidelines have ignored that LDL-cholesterol (LDL-C) of patients with acute myocardial infarction is lower than normal; that high cholesterol is not a risk factor for diabetics; that the degree of coronary artery calcification is not associated with LDL-C; and that 27 follow-up studies have shown that people with high total cholesterol or LDL-C live just as long or longer than people with low cholesterol.

Statin-Associated Cardiomyopathy Responds to Statin Withdrawal and Administration of Coenzyme Q.

Context: Heart failure (HF) is rapidly increasing in incidence and is often present in patients receiving long-term statin therapy.

Objective: To test whether or not patients with HF on long-term statin therapy respond to discontinuation of statin therapy and initiation of coenzyme Q (CoQ) supplementation.

Design: We prospectively identified patients receiving long-term statin therapy in whom HF developed in the absence of any identifiable cause.
