My heart rate is persistently above 100 bpm following a suspected cardiac event, and I am currently taking aspirin, Clavix (clopidogrel), and Ranx (ranolazine). Given my history of bronchitis and an oxygen saturation of 92%, is it safe to use a Salbutamol inhaler for relief, or could it further increase my heart rate?

Using a salbutamol inhaler can indeed further increase your heart rate and put extra stress on your heart, which is risky after a recent cardiac event. Given your persistent heart rate over 100 bpm, an oxygen saturation of 92%, and your current medications (aspirin, clopidogrel, and ranolazine), please avoid using the inhaler without direct medical supervision. These symptoms require prompt evaluation. I highly recommend contacting your cardiologist or seeking immediate medical attention so a healthcare professional can safely assess your heart and lungs together.
