Can removing salt from diet reduce symptoms of vascular conditions?

Yes-but not possible: It is nearly impossible to completely remove salt from the diet. You can have a "low salt" diet, where it is <1 gram per day -- or maybe less if you are amazingly disciplined. However, reducing salt intact can result in decreased blood pressure in patients who have hypertension (high blood pressure). It is usually part of a diet, exercise, and medication regimen.

Vascular conditions: Vascular conditions, aka cardiovascular disease is number one killer. Cancer number 2. Vascular conditions kill by cv events; stroke, heart attack, sudden death, organ failure, hemorrhage. Often no warning, before a cv event. Patients and docs work as a team to diagnose and treat, hopefully before event occurs. Manage hypertension, (low salt helps), control diabetes, lipids, stop nicotine.
