I had a heart attack a couple of months ago and I'm 47. They put in a stent and I've been doing okay. I walk about 5km every morning without any issues. Is it safe for me to start using a treadmill or go for some cycling now? Also, what should my pulse rate be on the treadmill panel? My resting heart rate is usually around 53. Would really appreciate your advice.

It's great that you are staying active after your heart attack. With a stent in place and your regular walking routine, you can gradually incorporate treadmill and cycling into your exercise regimen. When using the treadmill, aim to keep your heart rate within a safe range. For your age, a target heart rate during exercise is typically around 50-85% of your maximum heart rate. To calculate this, subtract your age from 220. So, for you, (220-47) = 173 beats per minute (bpm) is your estimated maximum heart rate. During treadmill exercise, aim to keep your heart rate between 85-147 bpm to ensure you are exercising safely. As for cycling, it is also a great cardiovascular exercise. Start slowly and gradually increase the intensity as tolerated. Pay attention to how your body responds and adjust accordingly. Remember to listen to your body, and if you experience any chest pain, dizziness, or unusual symptoms, stop exercising and seek medical attention.
