The authors argue that this is a better predictor of ventricular function than echocardiography, and in this study they used BNP levels to guide GPs' use of drugs.The results make interesting reading: the bottom line an important reduction in overall BNP levels, mostly by switching from one beta blocker to another. But at the end, only 28% had BNP levels below the target threshold. This might be the best that anyone could achieve, and illustrates the folly of assuming that ‘best practice’ can be applied universally.There is a comment about how many visits were made … ER -
