I am a 72 year old female. Have had a stent implant and by-pass 2/12 years ago. I do not drink Slim Fast as a regular diet, only when I need a 'quick breakfast' or such. The other day I had a Slim Fast for breakfast and a Slim Fast bar mid-morning. Shortly thereafter, I had heart palpitations and took my blood pressure. It was 209/88 when it is usually 123/70. Went to the doctor a few hours later and pressure was fine. Is there a correlation between the Slim Fast and my high blood pressure? There was nothing unusual going on that morning.
