Final answer:
Digoxin is contraindicated for a patient with hypertrophic cardiomyopathy because it is a positive inotropic agent that increases the strength of heart contractions, which can exacerbate the condition.
Step-by-step explanation:
The correct option : d
Hypertrophic cardiomyopathy is a condition in which the heart muscle becomes abnormally thick, potentially making it harder for the heart to pump blood. Treatment usually includes drugs that either reduce the symptoms or prevent complications. Negative inotropic agents, such as certain beta blockers and calcium channel blockers, can be beneficial as they decrease the strength of heart muscle contractions and reduce the oxygen demand of the heart.
However, Digoxin is a positive inotropic agent which increases the strength of heart muscle contractions by increasing intracellular calcium levels. In hypertrophic cardiomyopathy, such an increase in contractility can be harmful as it could exacerbate obstruction to blood flow out of the heart, potentially leading to worsening symptoms or complications. Therefore, Digoxin is contraindicated in patients with hypertrophic cardiomyopathy.
It's important to note that other drugs listed, such as Nitroprusside, Propranolol, and Verapamil, may be used in certain circumstances and under careful medical supervision to manage symptoms or comorbid conditions in patients with hypertrophic cardiomyopathy.
