Hi, Ramipril is a medication used to treat high blood pressure, and heart failure, and to improve survival following a heart attack. It belongs to a class of drugs known as ACE inhibitors, which work by relaxing blood vessels and reducing the workload on the heart. Chest pain and arrhythmias are potential side effects of Ramipril. These side effects may indicate a serious problem and require immediate medical attention. However, it is important to note that not all chest pain and arrhythmias are caused by Ramipril, and there may be other underlying medical conditions that are causing these symptoms. It is recommended to stop taking the medication and seek medical attention immediately if you experience any chest pain, difficulty breathing, or other symptoms that could be related to a heart attack. It is also important to talk to your doctor before stopping any medication, as sudden discontinuation of medication can have potential risks and may worsen certain medical conditions. If your doctor is not available, consider seeking medical advice from another healthcare provider or going to the emergency room. They will be able to evaluate your symptoms and determine the appropriate course of action. Take care. Hope I have answered your question. Let me know if I can assist you further.
