Summary

Beta-blockers should be administered to all patients with heart failure stages II to IV NYHA. It should also be administered to patients with stage I after myocardial infarction. The low ejection fraction, especially after myocardial infarction is a strong indication for beta-blockers, as many studies indicate that administration of these drugs substantially reduces cardiovascular mortality. Beta-blockers reduce mortality and hospitalizations and improve the operational phase for all categories of patients with heart failure. Since beta-blockers, only carvedilol, metoprolol, and recently visoprololi nevimpololi have shown these benefits and thus, only those have to be administered. The clinical study Carvedia aims to observe and record the action of beta-blocker carvedilol on cardiac function in patients with heart failure or reduced left ventricular ejection fraction after acute myocardial infarction.

Detailed description

The relationship between stroke volume, which is extruded from the left ventricle gives a measure for the restrictive left ventricular function. Any patient with known cardiovascular disease should undergo assessment of left ventricular function by measuring the ejection fraction. Several studies have shown that when the ejection fraction (LVEF), which measures the heart's ability to eject blood to the aorta does not exceed 40% (natural price \^ 50%) increased dramatically in the post-infarction mortality. The ejection fraction as a reliable predictor, can be measured by ultrasonography. The reduced ejection fraction is associated with an increased risk of life-threatening arrhythmias, heart failure and death. The low ejection fraction, especially after myocardial infarction is a strong indication for beta-blockers, as many studies indicate that administration of these drugs substantially reduces cardiovascular mortality.
