For over a century, nitroglycerin has been a cornerstone treatment for angina, and its primary mechanism involves relaxing blood vessels. This process is crucial to understanding **how does nitroglycerin help relieve angina preload?** by decreasing the heart's workload.

The Frank-Starling mechanism dictates that increased ventricular stretch leads to increased cardiac output, yet most vasodilators decrease preload. Understanding the complex relationship between `Medications,Pharmacology` and cardiac hemodynamics is crucial for comprehending how different vasodilators impact preload, and why the answer to the question, 'Do vasodilators increase preload?' is a definitive no.

Acute pulmonary edema, a life-threatening condition where excess fluid accumulates in the lungs, is often a result of severe heart failure. A critical medication in its emergency treatment is furosemide, a loop diuretic that operates through a distinct dual mechanism. Understanding **how does furosemide work in pulmonary edema** is essential to appreciate its effectiveness in rapidly relieving lung congestion and improving patient outcomes.
