HOW THE WORK IS MADE
Clear medical education requires visible sources, honest limits, and precise language about who has—and has not—reviewed the work.
The standard
HEART RESERVE is written for education and better clinical conversations. It does not diagnose, prescribe, predict an individual outcome, or create a clinician-patient relationship.
Medical claims are grounded in sources readers can open. Priority goes to current professional guidelines, scientific statements, systematic reviews, peer-reviewed research, and established public-health organizations. Sources are chosen for relevance—not because an organization endorses HEART RESERVE.
Lisa Zahakos, PA-C, writes and checks the educational material against the sources displayed on each page. Independent clinical review is named only after a qualified reviewer has reviewed the exact material and approved attribution in writing. Review is not endorsement.
Medical articles show a visible source-check date. Content is revisited when relevant guidance materially changes, an error is identified, or a page is substantially revised. The date describes that editorial check; it does not imply independent review unless a reviewer is named.
Factual errors are corrected promptly. A change that materially alters the meaning of published medical guidance will be identified on the page. Typographical and clarity edits may be made without a correction note.
Paid sponsorship, affiliate relationships, donated services, or other material conflicts will be disclosed beside the relevant content. A sponsor may not purchase a medical conclusion, hidden recommendation, testimonial, or editorial approval.
HEART RESERVE checks and planning tools are educational conversation organizers. They are not validated risk scores, diagnostic tools, medical records, exercise clearance, or substitutes for individualized care. Illustrative pilot designs remain subject to partner, clinical, privacy, and statistical review.
