 Hypertension is a common condition characterized by high blood pressure. It can lead to serious health problems if left untreated. A new study has found that elevated levels of lipoprotein, A, a type of cholesterol, are associated with essential hypertension. The researchers also observed a negative correlation between serum lipoprotein, A, and kidney function, suggesting that lipoprotein, A, could play a role in the development of essential hypertension. Further studies are needed to better understand this relationship.
