In a 72-year-old patient with severe aortic stenosis, what is the best approach regarding furosemide therapy?

In the context of a 72-year-old patient with severe aortic stenosis, managing volume status is critical. Furosemide, a loop diuretic, is used to alleviate fluid overload, which can exacerbate symptoms in patients with heart valve issues, including aortic stenosis. However, in this situation, reducing the dose of furosemide may be the most appropriate approach.

Patients with severe aortic stenosis often have reduced stroke volume and cardiac output due to the obstruction at the aortic valve. If diuretic therapy is aggressive, it can lead to significant dehydration and hypotension, as these patients depend on their preload to maintain cardiac output. A high dose of furosemide can exacerbate fluid depletion and worsen symptoms of heart failure rather than improving them.

Additionally, the management of severe aortic stenosis requires careful monitoring of fluid status. Over-diuresis can lead to decreased renal perfusion and worsen kidney function, which is a particular concern in older patients who may have baseline renal insufficiency. By reducing the dose of furosemide, fluid management can be optimized without compromising blood pressure and renal function, leading to a more stable condition for the patient.

Thus, adjusting furosemide therapy thoughtfully
