If your blood pressure is normal, that does not mean you can ignore how much salt you consume.
A high salt diet leads to:
Reduced functioning of the endothelium. The endothelium is the inner lining of blood vessels which mediates coagulation, immune function, and platelet adhesion.
Stiffening of arteries. The stiffer the arteries, the harder the heart works.
Enlargement of the muscle tissue comprising the wall of the heart’s main pumping chamber. This enlargement can cause the heart to not pump blood with optimal force and efficiency.
