Heart Disease - Hypertensive Heart Disease
Hypertensive Heart Disease This may be defined as the Cardiac abnormalities
and consequent symptoms, which develop because of long standing, elevated
blood pressure. The heart is forced to work to pump blood against an
increased resistance through the body. This leads to a gradual remodelling
of the heart muscle, which thickens, enlarges (Hypertrophies) and outgrows
its blood supply. The muscle becomes increasingly inefficient and eventually
the heart “fails”.
Failure implies that performance expectations are not being met, and fall
short of requirements in a given situation. In practice, patients first have
their Heart Failure drawn to their attention by
the presence of symptoms, which are due, either to congestion of certain
tissues and organs or attributed to inadequate blood flow through them.
Congestion develops where fluid accumulates in areas from which it should
have been pumped by the heart. The congestion may develop in the lungs
giving rise to the symptom of dyspnoea
(breathlessness), in the limbs & lowermost parts of the body, causing
oedema (swelling) or in the abdomen causing a
swollen liver and cescites (fluid filled
abdomen).
Prevention of Hypertensive Heart Disease:
This process of remodelling which produces Ventricular
Hypertrophy can be prevented by controlling the blood pressure. This
involves non-drug therapy such as correction of obesity, regular exercise,
and appropriate diet with low salt, high fibre as well as concomitant drug
therapy if needed. Furthermore, there is accumulating evidence that
long-term treatment with certain classes of
antihypertensive (blood pressure reducing) medications may reduce
some of the ventricular remodelling that may
have been previously present.
Since hypertension is
asymptomatic in the early stages and for a very long time while
congestions are developing, it is essential that blood pressure be checked
at regular intervals as a preventative measure.
If symptoms of heart failure develop, there are a number of options
available for relief. These include altered activity, dieting measures,
prescribed medication of which there is a great variety now available and in
extreme cases even invasive procedure such as
paracentesis.
