Which medicine class is prescribed to manage angina pectoris?

The correct answer is based on the primary role of anti-anginal agents in treating angina pectoris. Angina pectoris is characterized by chest pain due to insufficient blood flow to the heart muscle, often triggered by stress or exertion. Anti-anginal agents, such as nitrates, beta-blockers, and calcium channel blockers, specifically target the underlying mechanisms of angina by improving blood flow, reducing myocardial oxygen demand, or both, thereby alleviating the symptoms.

While beta-blockers are also effective in managing angina by reducing heart rate and contractility, they are considered a subclass of anti-anginal agents. However, the term "anti-anginal agents" broadly encompasses various medications that directly address the symptoms of angina. Therefore, this classification provides a more comprehensive answer regarding the management of angina pectoris.

Diuretics and anti-coagulation agents do not directly treat angina. Diuretics help reduce fluid overload and are primarily used for conditions like hypertension and heart failure, while anticoagulants prevent blood clot formation but do not improve blood flow to the heart muscle. Thus, the focus on anti-anginal agents is specifically relevant to managing angina pectoris effectively.
