Study shows genetics, not salt, cause of hypertension
A new study of more than 275,000 individuals from around the world makes it clear that hypertension is a condition that is genetically determined and is unrelated to salt consumption. The report from scientists at Massachusetts General Hospital (MGH) says that 28 specific regions of DNA were found to be associated with blood pressure in human patients. They also identified an important physiologic pathway in blood pressure control, potentially leading to a totally new class of hypertension drugs.
