Those tears make nice resting places for excess cholesterol. That means that the damage high blood pressure creates inside arteries and blood vessels can actually lead to even more plaque buildup and artery narrowing because of high blood cholesterol. In turn, your heart has to work even harder to pump blood, putting excess strain on your heart muscle.
High blood pressure usually has no signs or symptoms, so the only way to know if you have high blood pressure is to have yours measured. However, a single high reading does not necessarily mean you have high blood pressure. Many things can affect your blood pressure through the day, so your doctor will take a number of blood pressure readings to see that it stays high over time.
