Given the patient's history of coronary heart disease and myocardial infarction, what is the most likely rationale for prescribing nitroglycerin 0.4 MG/ACTUAT mucosal spray?
To treat acute heart failure by increasing cardiac contractility. To prevent bacterial infections due to its antimicrobial properties. To manage hypertension by directly lowering blood pressure over long-term use. To relieve episodes of chest pain (angina) by dilating coronary arteries and reducing cardiac workload.
