Explanation Nitroglycerin is the preliminary preferred treatment for angina pectoris and chest pain. The main mechanism behind considering nitroglycerin is that it relaxes the vascular smooth muscle. It dilates both arterial and venous beds. Vasoconstriction and vasodilatation are often coupled to change in cardiac output. Vasoconstriction is induced by the peptide, and vasodilatation is induced by the nitric oxide...

Chapter 42.4, Problem 3CC

Summary Introduction

To explain: The reason behind why nitroglycerin is preferred to relieve chest pain and used to treat heart disease patients.

Concept introduction:

Nitroglycerin is used as a vasodilator that opens blood vessels to improve blood flow. Angina results when there is imbalance between the oxygen supply and oxygen demand without a proportional increase in supply. The process of narrowing of arterioles is known as vasoconstriction. The process of relaxation of arterioles is known as vasodilatation.
