Background: Functional assessment of coronary artery obstruction is used in cardiology practice to correlate anatomic obstructions with flow decrease. Among such assessments, the study of the coronary fractional flow reserve (FFR) has become the most widely used.
Objective: To evaluate the correlation between FFR and findings of ischemia obtained by noninvasive methods including stress echocardiography and nuclear medicine and the presence of critical coronary artery obstruction.
Background: In individuals with concurrent chronic kidney disease (CKD) and cardiovascular disease (CVD), the association between left atrial volume (LAV) and serum levels of C-reactive protein (CRP) is shown.
Objective: Verify the presence of associations between systemic inflammation and LA dilation in patients on hemodialysis (HD) without clinically evident CVD.
Methods: This was an observational cross-sectional study of a population on HD (> 3 months), which excluded patients with acute or chronic inflammatory diseases (infections, malignancies, autoimmune diseases) hemodynamic instability, use of anti-inflammatory drugs, hyperparathyroidism, arrhythmias, mitral valve disease and prior cardiovascular (CV) events.
Background: The consequences and risks of prolonged physical exercise are not well established.
Objective: To evaluate the effects of prolonged physical exercise on the participants of a 24-hour ultramarathon race.
Methods: Twenty male runners were selected for evaluation a day before and immediately after the race, where the athletes had to cover the most distance in 24 hours.
