Introduction and %undamentals
of the Myogenic Theory
6he coronar% atherosclerosis and slo8 coronar% flo8 in the normal e@tramural coronaries develop
m%ocardial ischemic process through the imbalance bet8een demand and blood suppl% to the
m%ocardial segments$ dependent on the right and left coronar% arteries. !asicall%$ the large e@tramural
coronar% arteries are responsible for nutrition of the segmental m%ocardium and mainl% b% the
contractile balance of each segment of the ventricular 8all.
#ver% time 8hen is developed a relative coronar% insufficienc% through ph%sical or ps%cho3emotional
stress results in an immediate loss of contractilit% of the ischemic area and simultaneous e@altation ofother unaffected contractile ventricular segments.
6he continuit% of such repetitive ischemic manifestations tend to contribute to the installation of
nons%nergic segments$ b% ischemia Q loss of contractilit% and overload imposed b% the remaining
intact ventricular segments$ during the ventricular ejection phase.
6hus$ the coronariopath% contributes to the deterioration of the ventricular segment$ constituting areas
of m%ocardiosclerosis or segmental m%ocardial disease$ possible future site of the m%ocardial

Cardiotonic: The com'atible drug )ith
the Myogenic Theory
6he recent discover% of endogenous cardiotonic hormones digitalis$ strophanthin$ proscillaridine$ etc..0$ isolated from
human tissues and bod% fluids$ ma% represent a strong ne8 argument for the m%ogenic theor% of m%ocardial infarction.
An elevated concentration of endogenous cardiotonics have been found under different conditions such as sodium
imbalance$ h%pertension$ cardiac arrh%thmias$ chronic renal failure$ congestive heart failure and acute m%ocardial infarction.
igorous ph%sical e@ercises as 8ell ph%siological stress situations ma% also elevate the concentration of endogenous
cardiotonics in the bod%.
Ee thin5 the cardiotonics found in nature ma% complement a deficient production of endogenous cardiotonic hormonesproduced b% the human bod% and thus support cardiac metabolism and protect the heart from the infarction$ as proposed in
M%ogenic 6heor%.

6he ris5 of a heart attac5 or other acute m%ocardial events is not proportional to the
severit% of coronar% stenosis. Several studies in 8hich more than one angiograph% 8as
performed in patients 8ho developed acute s%ndromes sho8ed that most of these
s%ndromes appear to be developed from lesions that on the first angiograph% caused
not significant stenosis. 6hese less severe stenotic lesions lead to m%ocardial infarctionbecause the% have not developed a sufficient collateral circulation around that 8ould
prevent or limit the e@tent of m%ocardial necrosis. 6his means that a 2B reduction in
