The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
While the overall size of the heart might not typically decline with age (although it does in situations of extreme bed rest/inactivity), the size of the chambers often does - particularly the left ventricle - due to the concentric remodeling you mentioned! Sedentary older adults tend to have smaller, stiffer LVs.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
in addition to our heart getting stiffer our heart shrinks so it atrophies and um so our heart is getting smaller and it's getting stiffer and these sorts of structural changes are affecting our cardiovascular health and our cardiovascular performance right
generally speaking, as we age, our heart shrinks and it gets stiffer. It's stiffer with age. Um, and that's not a very good thing for cardiovascular health.
