How can digitalis/digoxin modulate stress on the heart and blood pressure?

Interesting. It's a complicated question. Digitalis, on its face, makes the heart squeeze a little harder and more forcefully. But the way we use it these days, its primary effect is to modulate the adrenaline system in the body, decreasing the levels of stress chemicals on the heart. Great question. Sorry i don't have more characters to give a longer answer.

What is the use of treatment with digoxin (digitalis) in heart failure?

Stronger, slower. When the heart fails, it decreases blood flow to organs. This can cause kidney injury, liver injury, fatigue, shortness of breath, swelling, and fluid build-up in the lungs. Digoxin makes the heart contract stronger and slows the heart rate. This pushes more blood forward to the organs. Digoxin is not used much for heart failure anymore, but it is used to prevent abnormal heart rhythms. Read more...
