It looks like there have been two studies on the role of ivabradine in HOCM in cats. These suggest its effect may be clinically significant, but inferior to atenolol.
Thanks James for your answar. Beta blocker, verapamil and disopyramide are generally used to treat HOCM. Few studies are available to evaluate the role of ivabradine in HOCM in cat as you mentioned .I think human study is needed with this molecule where beta blocker are contraindicated like associated severe COPD.
