MYOCARDIAL INFARCTION AND THE BETABLOCKERS TREATMENT
Abstract:
The medical use of beta-blockers in their
variant shapes and names was possible due to some
elaborate clinical studies that took a full swing in the last
decades: the so-called population studies on large
representative groups whose results grant us the handling
of these precious medical substances in the medical
practice. Beta-blockings have properties that intervene in
the myocardial ischemia treatment by adjusting the
prejudices made by hypoxia or by preventing other local
damages. Beta 1 stimulating hemodynamic effects are
antagonized, such as: the blood pressure decrease rate
leads to the ventricular contractility decrease rate, and
the ventricular wall pressure increases due to the
ventricular volume lift. The major effect is that of
reducing the increase of oxygen requirement with 20-30%
and the contraction in the ischemia area which is
improved.
