Cardiac function, myocardial fat deposition, and lipid profile in young smokers: a cross-sectional study.

Background: There is a possibility that cardiac morphometric characteristics are associated with the lipid profile, that is, the composition and concentration of triglycerides, total cholesterol, HDL, LDL, and others lipoproteins in young smokers without comorbidities. Thus, this study aimed to evaluate the association of cardiac morphometric characteristics, myocardial fat deposition, and smoking cessation with the lipid profile of young smokers.

Methods: A clinical and laboratory evaluation of lipids and the smoking status was performed on 57 individuals, including both a smoker group and a control group.

Serum Vitamin D Levels, Disease Activity Score-28 for Rheumatoid Arthritis with C-Reactive Protein (DAS28-CRP), and Cardiac Remodeling Determined by Ventricular Dimensions and Left Atrium Diameter in Patients with Rheumatoid Arthritis: A Prospective Observational Study.

BACKGROUND Rheumatoid arthritis (RA) can cause extra-articular manifestations, and the myocardium can be a target. This study aimed to describe structural and functional cardiac echocardiographic variables in RA patients and to evaluate whether vitamin D (VD) levels and inflammation markers, evaluated by Disease Activity Score-28 for Rheumatoid Arthritis with C-reactive protein (DAS28-CRP), are associated with cardiac remodeling (CR) in this population. MATERIAL AND METHODS This prospective observational study evaluated 90 patients with RA in Botucatu University Hospital wards from 2014 to 2017.

Green Tea () Extract Increased Topoisomerase II, Improved Antioxidant Defense, and Attenuated Cardiac Remodeling in an Acute Doxorubicin Toxicity Model.

Experimental studies have shown the action of green tea in modulating cardiac remodeling. However, the effects of green tea on the cardiac remodeling process induced by doxorubicin (DOX) are not known. Therefore, this study is aimed at evaluating whether green tea extract could attenuate DOX-induced cardiac remodeling, assessed by cardiac morphological and functional changes and associated with the evaluation of different modulators of cardiac remodeling.

Pamidronate Attenuates Oxidative Stress and Energetic Metabolism Changes but Worsens Functional Outcomes in Acute Doxorubicin-Induced Cardiotoxicity in Rats.

Background: Cardiotoxicity is the major side effect of doxorubicin. As mechanisms that are involved in cardiotoxicity are ambiguous, new methods for attenuating cardiotoxicity are needed. Recent studies have shown that bisphosphonates can decrease oxidative stress.

Green tea (Cammellia sinensis) attenuates ventricular remodeling after experimental myocardial infarction.

Background: Considering the high morbidity and mortality after myocardial infarction (MI), the study of compounds with potential benefits for cardiac remodeling is reasonable. Green tea (GT) (Cammellia sinensis) is the most consumed beverage in the world. The potential action mechanisms of GT include anti-inflammatory, anti-apoptotic, antioxidant, and lipid-lowering properties.

The role of lipotoxicity in smoke cardiomyopathy.

Background/aims: Experimental and clinical studies have shown the direct toxic effects of cigarette smoke (CS) on the myocardium, independent of vascular effects. However, the underlying mechanisms are not well known.

Methods: Wistar rats were allocated to control (C) and cigarette smoke (CS) groups.
