What type of medication increases the force of cardiac contraction?

Medications that increase the force of cardiac contraction are typically classified as positive inotropes, and this is particularly relevant for the treatment of congestive heart failure. These agents improve the heart's ability to pump blood effectively, which is crucial for patients with weakened cardiac function typically seen in congestive heart failure.

Congestive heart failure agents often include drugs like digoxin, which enhance cardiac contractility. By increasing the strength of contraction, these medications help alleviate symptoms and improve the overall cardiac output, making them essential in the management of heart failure.

In contrast, anti-arrhythmia agents primarily focus on restoring normal heart rhythm rather than improving contraction force. Anti-anginal agents aim to reduce myocardial oxygen demand and alleviate chest pain, typically without influencing the contractility of the heart. Anti-coagulation agents function to prevent blood clot formation and do not have a direct impact on cardiac contractility. Therefore, the choice that correctly identifies medications that enhance the force of cardiac contraction is indeed those used in the treatment of congestive heart failure.
