Which one of the following drugs is commonly prescribed for heart failure HF )?
There are many different types of diuretic, but the most widely used for heart failure are furosemide (also called frusemide) and bumetanide. Possible side effects of diuretics include dehydration and reduced levels of sodium and potassium in the blood.
Which of the following are typical medications used in the treatment of heart failure?
These drugs slow your heart rate and reduce blood pressure. Beta blockers may reduce signs and symptoms of heart failure, improve heart function, and help you live longer. Examples include carvedilol (Coreg), metoprolol (Lopressor, Toprol-XL, Kapspargo Sprinkle) and bisoprolol.
Which of the following describes difficulty breathing when lying flat?
Sometimes, people find it hard to breathe when they are lying down flat. The medical term for this is orthopnea.
What is the first drug of choice for heart failure?
Digoxin has been the traditional first drug of choice for CHF, but with protracted controversy about its efficacy and safety. It is hope that new agents as vesnarione, and ibopamine may improve contractility without having adverse consequences.
What is digoxin used for?

Bisoprolol (Zebeta) Metoprolol succinate (Toprol XL) Carvedilol (Coreg) Carvedilol CR (Coreg CR) Toprol XL.

Which of the following are used as first-line treatment for congestive heart failure?
First-line therapies for heart failure with reduced ejection fraction (HFrEF) ACE inhibitors (ACEIs), ARBs, beta-blockers, MRAs and diuretics form the basis of first-line pharmacological management of left ventricular systolic heart failure (HFrEF).
What is a heart cough?
What is a heart cough? In heart failure, your heart muscle has dysfunction that might be due to weak contraction or stiffness. This can allow fluid to back up in yout lungs, creating a condition called pulmonary edema. Your body coughs persistently in an effort to eliminate the excess fluid.

And that's how you get what we call a cardiac cough.
Why do I feel breathless while sleeping?
Sleep apnea is one of the most common reasons people have a shortness of breath while lying down. Often confused with mere snoring, obstructive sleep apnea (OSA) causes shallow breaths or pauses in breathing while asleep. The muscles in your throat relax and obstruct your airways, especially when lying on your back.
What is the mainstay of diuretic therapy for HF?
In general, due to their greater effectiveness, loop diuretics, such as furosemide, are the mainstay of diuretic therapy in HF.
Why do we need diuretics?
Diuretics are used to achieve and maintain euvolaemia (the patient’s ‘dry weight’) with the lowest possible dose. This means that the dose must be adjusted, particularly after restoration of the dry body weight, to avoid the risk of dehydration, which leads to hypotension and renal dysfunction.[10] .
What are the different types of loop diuretics?
Loop diuretics include furosemide, bumetanide, torsemide and ethacrynic acid. While the bioavailability of oral furosemide ranges from 40 to 80 %, the bioavailability of torasemide and bumetanide exceeds 80 %; so these two molecules may be more effective in treating patients suffering from HF.[7]
What is loop diuretic?
Loop diuretics remain a cornerstone in the pharmacological treatment of ADHF and are administered in about 90 % of patients hospitalised for HF.[1] . These drugs are routinely used as initial therapy in ADHF due to their ability to greatly improve the symptoms.
How much sodium is reabsorbed in the collecting duct?
Only 3 % of filtered sodium is reabsorbed at the collecting duct, so this class of drugs does not have an appreciable diuretic effect. However they are often used in association with other more effective diuretics to correct or prevent potassium deficiency.
Why are sodium ducts less effective in glomerular filtration?
They are less effective in patients with reduced glomerular filtration, because they exert their diuretic effects from the luminal side of the nephron.
What is the most common cause of hospitalisation in patients over the age of 65?
HF is the most common cause of hospitalisation in patients over the age of 65.[2] . The main manifestations of the syndrome are symptoms resulting from vascular congestion, such as shortness of breath, abdominal distension, oedema formation and symptoms resulting from low systemic perfusion.
What is the main goal of diuretics?
The main goal of diuretics is to reduce the amount of fluid in the body. This leads to symptom relief, lower blood pressure and a decreased risk of hospitalization for heart failure. 2
How does diuretic work?
There are different classes of diuretics and each works in a distinct way in the kidneys to remove fluid buildup from the body which reduces pressure on blood vessel walls. 2-3 As the kidneys eliminate the excess water from the blood, the total blood volume that the heart has to pump is reduced, which causes blood pressure to go down and makes it easier for the heart to pump forward. 4
Can diuretics cause low potassium?
Common side effects of diuretics include muscle weakness, fatigue, or low potassium. Most people experience an increased frequency of urination. Medications can take time to work properly and get adjusted. Diuretics tend to work quickly and doses may need to be adjusted frequently. If you find that frequently going to the bathroom interferes with your sleep or certain activities, talk to your doctor about adjusting the medication schedule. 1
