Cardiovascular drugs are medications used to treat conditions related to the heart and blood vessels. They help manage issues such as high blood pressure, heart failure, and irregular heartbeats. Common types include beta-blockers, ACE inhibitors, and statins, each serving different purposes in improving heart health. These drugs work by various mechanisms, such as relaxing blood vessels, reducing heart workload, or lowering cholesterol levels. Proper use of cardiovascular drugs can significantly reduce the risk of serious complications, including heart attacks and strokes, making them essential in managing cardiovascular diseases.
