Lowering Heart Rate Post Revascularization

Potential interests of heart rate lowering drugs.

Epidemiological studies have shown that a high heart rate at rest is a risk factor for global and cardiovascular mortality. 1–3 A rapid heart rate is associated with a variety of prognostic factors indicative of worse heart conditions (for example , hypoxaemia, anaemia, alcohol consumption , low physical training status). The link between a high resting heart rate and an increase in overall and...

[Heart rate variability and pulmonary infections after myocardial revascularization].

BACKGROUND heart rate variability (HRV) is a noninvasive diagnostic method used in the assessment of the autonomic modulation of the heart. The assessment of HRV using nonlinear dynamics methods in the preoperative period of surgical myocardial revascularization could be predictive of morbidity such as pulmonary infections in the postoperative period. OBJECTIVE to evaluate the behavior of HRV...

Lowering of the Heart Rate in Massive Pericardial Effusion

E LECTRICAL ALTERNANS is characteristic of pericardial effusion, especially of neoplastic origin. This phenomenon has been explained by increased cardiac motion or rotation due to the excessive fluid in the pericardium.' This assumption has been supported by studies employing reflected ultrasound.2 In addition to the excessive motion of the heart, rapid heart rate has been considered a critical...

Ivabradine, the pure heart rate-lowering drug, shown to reduce morbidity and mortality in heart failure

Revascularization for heart failure.

Coronary artery disease is the most common underlying cause of heart failure, yet there is little consensus on the role of revascularization in the management of patients with ischemic cardiomyopathy. The concept of recovery of dysfunctional but viable myocardium forms the pathophysiologic basis for the benefit of revascularization. Data from observational studies suggest that patients with cor...
