Which is not considered a first-line treatment for stable angina?

In the context of treating stable angina, first-line treatments typically include beta-blockers, calcium channel blockers, and long-acting nitrates. These medications are specifically designed to alleviate chest pain associated with angina by either reducing myocardial oxygen demand or improving oxygen supply to the heart.

Statins, while important in managing cholesterol levels and reducing cardiovascular risk, do not directly relieve the symptoms of stable angina. Their primary role is in the prevention of cardiovascular events rather than immediate symptomatic relief. This distinction makes statins an adjunctive therapy rather than a first-line treatment for managing stable angina.

In summary, the inclusion of statins as a necessary treatment for stable angina sets it apart from the other options, which directly target the physiological mechanisms involved in angina pectoris.
