Coronary artery disease occurs
when the blood vessels that supply blood to the heart muscle (coronary
arteries) are narrowed or blocked. This narrowing or blockage most often is
caused by the buildup of fatty deposits, which is called atherosclerosis, or
hardening of the arteries.
High blood pressure increases the risk
of atherosclerosis by damaging the lining of the arteries and increasing the
likelihood that fatty deposits may form in them. Over time, this can lead to a
Hypertensive heart disease
occurs when high blood pressure causes the walls of the lower left heart
chamber (left ventricle) to become thick and stiff, which affects the heart's
pumping ability. This may in turn lead to heart failure, a condition in which
the heart cannot pump enough blood to meet the needs of the body.

for heart disease, and whether your high blood pressure has caused organ
