heart failure
"I had a virus infection of the back wall of my heart. In Feb 2007, my EF was 20% and I was throwing PVC's like crazy. My cardiologist started me on Coreg (carvedilol) but could not tolerate a dose higher than 3.125mg and he also started me on Vasotec (enalapril) and, again, I could not tolerate a dose higher than 2.5mg. In fact, I take my blood pressure before every dose (2x daily) and if it is less than 130, I do not take the Vasotec. 

By June 2007, my EF was 68% and only the occasional PVC these days. 

Coreg and Vasotec continue to work very well and have saved my life!"
