The best thing for your heart is co-Q10 or ubiquinol which is supposed to be more potent. It feeds the heart. Gives you energy. Swanson vitamins has it at a good price. I'd start with 100mg of co-q10 and see how you do, you may need more, depending on your body weight. I used it back in the mid 80's to heal my cat's hypertrophic cadiomyopathy. I used 3x his weight twice daily (30mg 2x day). When I took him back to the vets 7 months later for an ultrasound, his heart was normal size. The only side effect from it was a floppy valve that gave him a murmur. He lived 11 more years to the ripe old age of 18.
