Furosemide, sold under the brand name Lasix among others, is a loop diuretic medication used to treat edema due to heart failure, liver scarring, or kidney disease. [4] Furosemide may also be used for the treatment of high blood pressure. [4] It can be taken intravenously or orally. [4]
Loop diuretics usually have a ceiling effect whereby doses greater than a certain maximum amount will not increase the clinical effect of the drug. Also, there is a threshold minimum concentration of loop diuretics that needs to be achieved at the thick ascending limb to enable the onset of abrupt diuresis.
The term "calcium-sparing diuretic" is sometimes used to identify agents that result in a relatively low rate of excretion of calcium. [5] The reduced concentration of calcium in the urine can lead to an increased rate of calcium in serum. The sparing effect on calcium can be beneficial in hypocalcemia, or unwanted in hypercalcemia.

"Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80."
The Bainbridge reflex is most strong when heart rate is low; when heart rate is already high, additional venous return to the right atrium (i.e. additional increases in blood volume) will indirectly cause relatively greater stimulation of arterial baroreceptors which will reduce the heart rate. Thus, the effect of the Bainbridge reflex on heart ...

Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.
This is a classic symptom of a heart attack often shown in movies and TV dramas, but other warning signs can be more subtle, especially in women. Chest pressure It can feel like a tightness in the ...
