Question: Is It Safe To Take Creatine Monohydrate If You Have A Low Heart Rate?

I have a low resting heart rate. It is around 48 - 49 beats per minute. I was wondering what kind of side effects, if any, would be present if I were to start taking creatine monohydrate? Would there be anything to cause my heart rate to drop any when I stopped working out or would it be entirely safe for me to take creatine monohydrate?

Answer #1

I started taking creatine. But, since I had cardiac bypass surgery last July, I asked my cardiologist if it was ok to take it. He said no because of the water that was supposed to build up in muscle tissue. Since the heart is a muscle, he said he didn't like the idea and it would be better not to take it. I am not looking for someone to contradict him. What I am looking for is results of any study that shows the effects of creatine on the heart. My cardiologists said he couldn't find anything except what I told him about the water gain. Can you guys help me?


Answer #2

I wouldn't take creatine if you're having problems associated with your heart. Last September, I was diagnosed with supraventricular tachycardia or rapid heart-rate. I had taken creatine over the winter of '98 to bulk up for cycling the following season of '99. I witnessed a dramatic decrease in my resting heart rate (60 to 47), an inability to really max out my heart without great discomfort, and a persistent pounding sensation. This pounding was exponentially perceivable when my heart rate was up. During the '99 biking season, I trained normally and really had no problems other than the aforementioned. But in September of 1999, my heart began racing in a very odd fashion. By the end of the month, I was hospitalized for two days because my heart rate was very sensitive to any movement. My heart rate would go from 60 to 90 just from turning over in bed. What brought me to the hospital though in the first place was a heart rate of 150 with blood pressure of 190/115 that persisted for over two hours. Since then, I have heard that creatine can cause the heart to stretch much faster. Whether or not this is the cause of my problems is hard to determine, but I'm researching it!
