Cardiovascular agents are medications used to treat conditions related to the heart and blood vessels. They can help manage issues such as high blood pressure, heart failure, and irregular heartbeats. Common types of cardiovascular agents include beta-blockers, ACE inhibitors, and calcium channel blockers, each working in different ways to improve heart function and blood flow. These agents can also reduce the risk of serious complications like heart attacks and strokes. By regulating heart rate, lowering blood pressure, and improving circulation, cardiovascular agents play a crucial role in maintaining overall cardiovascular health and enhancing the quality of life for patients.
