Final answer:
IV antiplatelet agents may be used for chest pain in certain cases, such as STEMI. They may also be used preventively when plaque buildup is present but there is no major obstruction. Additionally, they can be used to treat high blood pressure, angina, and some abnormal heart rhythms.
Step-by-step explanation:
IV antiplatelet agents may be used for chest pain in certain situations. For example, in those with a STEMI (ST-elevation myocardial infarction), clopidogrel plus aspirin (dual antiplatelet therapy) is often prescribed to reduce cardiovascular events.
In addition, IV antiplatelet agents may be used preventively when plaque buildup is evident but there is not yet a major obstruction in the artery. This is known as dual antiplatelet therapy (DAPT) and involves using aspirin in combination with another antiplatelet drug.
Furthermore, IV antiplatelet agents may be used to treat high blood pressure, angina (chest pain) caused by reduced blood supply to the heart muscle, and some abnormal heart rhythms.
