It is probably not appropriate to ask what hypertensive heart disease causes, as hypertensive heart disease is damage to the heart caused by hypertension. Thus, the sequence of events is hypertension, progressing to damage to the heart, after which there are many possibilities of further harm. Perhaps the most common forms of hypertensive heart disease are left ventricular (the main pumping chamber of the heart) hypertrophy (increase in muscle mass) and left ventricular dilatation (enlargement of the chamber size most often along with 'thinning' of the muscle wall). Hypertrophy may initially be compensatory, meaning that the heart will be able to maintain its output despite the pressure gradient that it pumps against. Unfortunately, all compensatory changes are designed as a short-term 'fix', and all eventually lead to further damage. This is where the dilatation fits in. A dilated left ventricle has a weakened muscle wall and does not eject blood as efficiently. This is systolic heart failure. Although I am fond of the term heart 'failure', I do not have a better term to offer. Perhaps you may think of it as the heart failing to pump enough blood to nourish the body's organs and tissues. In 1980, a diagnosis of heart failure foretold a five year mortality of 95%, but at this time, the diagnosis suggests a five year survival of 85 to 95% depending upon many co-morbid conditions. As you did not provide much information as to why you were asking the question, I am only able to provide a partial answer. If you need additional information please email me more details at johnerussomd@jhu.edu. I wish you the very best of health and may God bless.
