Additive beneficial effects of beta blockers in the prevention of symptomatic heart failure

Beta Blockers and Heart Failure

reduced longevity.1 Heart failure can be due to systolic or diastolic left ventricular dysfunction. Most patients with heart failure have primarily systolic dysfunction. In two-thirds of patients with systolic dysfunction, the cause is coronary artery disease.2 However, patients may also have nonischaemic causes of cardiomyopathy such as hypertension, valvular heart disease, myocarditis, system...

Beta-blockers and heart failure

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Beta-blockers in heart failure. Future directions.

The rationale for beta-blockade in heart failure is now well established. Heart failure mortality, which is predicted by neurohormonal activation, remains high despite modern treatment including ACE inhibition, and additional neurohormonal blockade has further therapeutic potential. Previous clinical trial experience in heart failure, most of which has been in patients with idiopathic cardiomyo...

Beta-blockers in chronic heart failure.

Chronic heart failure (CHF) constitutes a significant clinical issue due to its increasing prevalence in general population and still fatal prognosis. During last twenty years the significance of beta-blockers in the treatment of CHF has changed. It resulted from the hypothesis from 1975 that in the course of CHF it comes to the activation of sympathetic system and renin-angiotensin-aldosterone...
