What is the effect of Nitroglycerin on patients with myocardial infarction?

• A. Vascular constriction
• B. Hypertension
• C. Prevention of arterial occlusion
• D. Increased heart rate

Answer: (C)

Nitroglycerin is primarily used in the treatment of myocardial infarction (MI) because it acts as a vasodilator. It relaxes the smooth muscle in the blood vessels, leading to the dilation of veins and arteries. This vasodilation allows for improved blood flow and oxygen delivery to the myocardial tissue affected by the infarct. When it comes to the option for the prevention of arterial occlusion, nitroglycerin contributes by reducing the workload on the heart and decreasing myocardial oxygen demand. This can help mitigate further ischemia (lack of oxygen) and limit the extent of damage during a myocardial infarction. By alleviating some of the stress on the heart, nitroglycerin can support the body in maintaining coronary perfusion. Other responses, like vascular constriction, hypertension, and increased heart rate, are not effects associated with nitroglycerin. Instead, the drug promotes vasodilation and helps to reduce blood pressure, thereby lowering the heart's workload. Hence, nitroglycerin's role is beneficial in the context of myocardial infarction, particularly by facilitating better blood flow and reducing the chances of further complications.
