To clarify i feel that if i incorporate a heart in your logo design i probably would be going in the wrong direction for 2 main reasons:
1.- Health not always refers only to heart disease conditions, there are other several health problems not only cardiovascular ones in any family.
2.- Most logos that use a heart as part of a logo might be confused with social dating services.
Taking in consideration this thoughts i wonder if you still be interested about incorporating a heart to my proposal in some way, i know using a cross is out from your interest,consider a using the heart element would be important to give the correct message, thanks.
Here's the meaning and the concept it contains entry #8, i hope you agree:
1.- Healthy person with joy raising arms BTW many designers are kind of copying it. 2.- Abstract flower bloom which remind us of life's natural balance. 3.- RSS icon which is commonly refereed for remote mobile and web services. 4.- All seen EYE which is always pending and looking forward all family members wellness. 5.- Finally bright colors refer to health, energy and wellness with trustworthy service. 6.- Modern and clean logo easy to identify and remember.
