I just had my second echocardiogram being on Camzyos. I started with a LVOT gradient of 100mmHG and my EF was 79. After taking 5 mg for a 4 weeks my LVOT gradient dropped to 16mmHg and my EF was 73. I was changed to 2.5 mg camzyos for weeks 5-8 and today my LVOT gradient increased to 21mmHG and my EF was 67. All great news as I would have been taken off the drug if my LVOT was below 20. I am feeling great and fortunate that I am reacting well to camzyos so far. As many of you know, the opposite reaction is frustrating and can be frightening.
