Coronary
heart disease (CHD) is the most common disease in most countries of the
world,it occupies a leading place among all causes of morbidity, mortality, and
persistent disability. According to epidemiological studies of coronary heart
disease it is more prevalent in males. The main mechanisms of CHD development
are: coronary atherosclerosis; coronary spasm ; microcirculation disturbance,
and coronary thrombosis,which occur against a background of internal and
external risk factors (age, gender, psycho-emotional factors, smoking, obesity,
dyslipoproteinemia, hypertension , heredity, etc.). The prescence of each
factor and their combination exacerbates the development and course of CHD. The
combination of coronary artery disease with diabetes (1 or type 2) doubles the
risk of CHD.
According to the WHO Expert - Diabetic
cardiomyopathy refers to a specific metabolic diseases of the heart muscle. One
of the most common mechanisms of metabolic abnormalities in the myocardium is a
defect in ATPase activity of muscle fibers of the heart due to modification of
sulfhydryl groups. In DM type-1 on the background of the metabolic imbalance
develops a mismatch between myocardial energy supply and demand it of oxygen,
increasing at low load and leading to dystrophic changes in myocardium. For
women before menopause, regardless of blood pressure levels, the effect of
aging on the structure and endothelial function was less pronounced than in
men, which defines a lower risk of cardiovascular accidents. This effect is
associated with endothelium-protective features of endogenous estrogens, which
affect the increase in the release of nitric oxide. Long history of diabetes
type 1, the presence of the generation of localized microangiopathy aggravates
the course of cardiomyopathy with development of vascular lesions, even before
the development of noncoronary chronic ischemic heart disease (aged 30 years
and above). Under the influence of one or more risk factors expressed forms of
cardiomyopathy may be complicated by myocardial necrosis in the absence of
organic lesions of the coronary arteries.
On the example of a clinical case, we
want to demonstrate features of the development and course of infarction in
patients with diabetes mellitus type 1 at age 37 with preserved menstrual
function.
Mutual burdening microangiopathic changes of coronary
vascular disorders of autonomic regulation of vascular tone and heart rate
variability as a result of diabetic neuropathy, hypertensive manifestations
and progressive endothelial dysfunction
were the cause of recurrent myocardial infarction in our patient, despite low
levels of atherogenic fractions and baseline total cholesterol.
Should pay attention to the burdening of
the metabolic lesion of the heart muscle with diabetes mellitus type 1 with a
long history of moderate hypertension, uncontrolled hyperglycemia and
endothelial dysfunction.
In order to prevent complications demonstrated by the
example of a clinical case, there should be regular monitoring of the
endothelial function of metabolic disorders and a constant and adequate
correction for the development of diabetes type 1.
