Deepak, when we think about sodium from a broader cardiovascular perspective, what does the evidence tell us about cardiometabolic and cardiovascular risk from increased sodium intake?

Sure, like other clinicians, me as well, blood pressure is the first one that comes to mind.

But through my research and readings, we are now learning more and more that sodium's impact extends well beyond blood pressure measurements and hypertension alone.

The evidence links higher dietary sodium intake with increased risk of other cardiometabolic risk factors, such as diabetes and obesity, in addition to hypertension, of course, as well as, importantly, clinical outcomes, major adverse cardiovascular events, such as stroke, heart failure, atherosclerotic CBD, kidney disease, and some literature even suggesting dementias as well.

So while elevated blood pressure might explain a lot of this relationship, sodium can also influence cardiovascular health through other effects on vascular function and other physiologic pathways.

There are observational studies that demonstrate greater risk of adverse cardiovascular outcomes such as heart failure in relation to dietary sodium intake completely independent of hypertension and blood pressure.

It's also important to note that people who are normotensive can still be salt-sensitive, and this in and of itself is associated with worse long-term outcomes.

Are there any particular populations that appear to be especially sensitive to sodium exposure?
