Medicine and salt: Who needs more pills?
Is the effect of antihypertensive drug therapy on blood pressure control and prevalent cardiovascular disease associated with dietary sodium-potassium ratio? A cross-sectional study based on NHANES

Surprising Findings
Dietary sodium-potassium ratio had no effect on blood pressure control or CVD risk in treated hypertensive adults.
Public health campaigns have long emphasized reducing salt and increasing potassium as key to heart health. This study challenges that in medicated patients.
Practical Takeaways
If you're on multiple blood pressure meds but still not at target, talk to your doctor about underlying causes — not just adding another pill.

Eating too much salt compared to potassium might be worse for your heart over time than just looking at salt or potassium by itself.
For US adults with high blood pressure who are on medication, whether they eat more sodium or potassium doesn't change how well their blood pressure drugs work or their risk of heart disease.
In human blood vessel cells, too much salt compared to potassium makes damage from a blood pressure-related substance worse, but two blood pressure medicines (losartan and a combo of losartan with amlodipine) still work just as well to protect the cells, even when salt levels are high.
For adults in the U.S. who already take blood pressure medicine, adding a second type of drug doesn’t seem to help them reach healthy blood pressure levels more than just sticking with one medication.
Adults in the US who take more than one blood pressure medicine tend to have more heart problems than those taking just one, which might mean their hearts were already in worse shape to begin with.
