The authors compare distribution of genotype frequencies and alleles of I/D of ACE gene polymorphism in patients with various forms of ischemic heart disease (IHD): with acute myocardial infarction (MI), stable effort angina (functional class II-III); in patients with postinfarction cardiosclerosis (PICS). A relationship was found between I/D polymorphism and acute MI. Frequency of DD genotype in MI patients was 0.57, in controls--0.21, p < 0.0001, RR = 4.9. The DD genotype may serve a marker of hereditary predisposition to MI. Genotype DD frequency in the group with acute MI was higher than that with PICS. In acute MI frequency of allele D was 0.76, in PICS--0.51, p < 0.0005. It is suggested that low frequency of genotype DD in the PICS group results from higher lethality of patients with DD genotype in the nearest rehabilitation period. Patients with repeated MI have a significantly higher frequency of genotype DD and complications after MI. Thus, there is a relationship between insertion-deletion polymorphism of ACE gene and myocardial infarction. Deletion DD genotype raises the risk to develop MI and probability of life-threatening complications and repeated MI.

The results of a study dealing with the specific features of silent myocardial ischemia (SMI) in male patients aged over 70 years are presented. Prolonged episodes of silent myocardial ischemia have been ascertained to be more frequently encountered in patients with ischemic heart disease (IHD) as high functional class angina pectoris on exertion, postinfarct cardiosclerosis, arterial hypertension, atherogenic blood lipid disturbances and they increase a total risk for SMI provided that they are combined. All this leads to destabilization of coronary blood flow and becomes a trigger for the development of prognostically significant cardiac arrhythmias by complicating the course of IHD and increasing the cost of drugs.

An evaluation was done of the character and circadian patterns of cardiac rhythm in 157 patients with ischemic heart disease, postinfarction cardiosclerosis, who ranged from 34 to 73 years old, with a history of preinfarction and early postinfarction stenocardia. It has been found out that in patients with postinfarction cardiosclerosis there prevail supraventricular and ventricular extrasistole in the structure of the heart's rhythm disturbances. Other rhythm disturbances occur very seldom. Supraventricular and ventricular tachycardia are more commonly seen in patients with a history of early postinfarction angina. The above patients demonstrate an increase in both the number of extrasystoles and in their gradation suggesting to us an electrical instability of the myocardium. Ventricular extrasystole was seen significantly less frequently in those patients presenting with preinfarction stenocardia, which fact might be related to a protective action of the ischemic preconditioning phenomenon.

Antiarrhythmic activity of oral allapinin was studied in 64 patients with ischemic heart disease. 27 of the patients had undergone coronary artery bypass grafting 2 to 12 months before, 19 patients had postinfarction cardiosclerosis, 38--arterial hypertension, 30--circulation insufficiency stage I. Arrhythmia presented as ventricular extrasystole (n = 28), paroxysmal atrial fibrillation (n = 18), paroxysmal atrial tachycardia (n = 11), frequent supraventricular extrasystole (n = 7). Arrhythmia continued from 6 months to 8 years. An effective single dose was defined with acute pharmacological test. The treatment course lasted for 21 days. Allapinin proved to be highly effective: ventricular ectopic activity was suppressed in 71.4% patients, atrial tachycardia paroxysms were prevented in 72.7%, paroxysms of atrial fibrillation--in 77.8%. Allapinin tolerance was good. Extracardiac side effects occurred most frequently, but dose lowering was necessary only in 6.2%. The drug was discontinued because of cardiac side effects in 4.7% cases. ECG monitoring is a highly informative method of the treatment efficacy control.

Hemodynamics and ventricular remodeling were studied echocardiographically in 192 men with heart failure (NYHA functional class I), arterial hypertension (AH) of stage I-III and clinical picture of ischemic heart disease (IHD). The latter presented in the patients with stable angina pectoris of FC I-II (SAP), unstable angina pectoris (UAP) without foci, paroxysmal atrial fibrillation, acute myocardial infarction (MI), postinfarction cardiosclerosis (PC) with SAP or UAP. The control group consisted of 41 healthy men. The patients had AH stage 1. The patients and healthy controls differed significantly by the size of the aorta, left atrium, thickness of the interventricular septum and posterior wall of the left ventricle. There was a significant left-ventucular hypertrophy in the groups with patients with MI, SAP and PC, UAP and PC (p < 0.001). In these groups the type of left ventricular remodeling was characterized as excentric type of left ventricular hypertrophy without its delatation. Normal left ventricular geometry was in healthy men, SAP, UAP, paroxysmal actual fibrillation.

Cholesterol (CH) acceptance ability of high density lipoproteins (HDL) was assessed in 43 ischemic heart disease (IHD) patients, including patients with post-infarction cardiosclerosis and class II-III effort angina. CH acceptance ability of HDL was measured as increment of HDL CH after incubation with artificial CH-containing system. Oxidabilities of HDL and total plasma were estimated by quantitation of lipid peroxidation products (hydroperoxides and thiobarbituric acid-reactive substances - TBARS) after incubation with Cu(2+) ions. HDL fraction (after apo B lipoproteins removal) of IHD patients appeared to include 2 times less additive CH compared with donor's HDL despite lower (-12%) HDL CH level. Negative correlation (r =-0.38, p<0.05) existed between formed TBARS in HDL and HDL CH acceptance. In total plasma of IHD patients elevation of both formed TBARS and particularly hydroperoxides was observed. Parallelism between decrease of CH acceptance by HDL, oxidability of HDL and of total plasma testifies on weakness not only of CH-accepting, but also of antioxidant HDL functions in IHD patients.

We studied pharmacodynamics of an amino acids complex (AAC) in 60 elderly patients (a mean age 71.6 years) with ischemic heart disease, postinfarction cardiosclerosis (PIC), circulatory insufficiency stage I-II. The patients were randomized into 3 groups, 20 persons each. Group 1 received standard therapy (ST) and placebo, group 2--ST + AAC (one tablet of 70 mg 3 times a day), group 3--ST + AAC sublingually in the same dose. Clinical symptoms, results of ECG Holter monitoring and echocardiography were assessed before the treatment and on treatment day 18. Positive effects of AAC used in combination with ST in relation to clinical symptoms, myocardial contractility and ischemia. No differences in efficacy were observed with oral and sublingual AAC administration.

A total of 37 autopsy cases were divided into two groups. Group 1 consisted of 17 victims who had died of closed blunt trauma of the chest with isolated heart contusion made by fists, feet in shoes. Group 2 (control) consisted of 20 cases of sudden death of ischemic heart disease because of atherosclerotic cardiosclerosis. Fragments of the heart containing endocardium were studied on the microscope JEIL-SM200 (Japan). Endocardium pathomorphology was represented by relief changes of the endocardium, structural arrangement of separate groups of muscular fibers above the endocardium surface, hemorrhages and blood clots, endotheliocyte desquamation, prelacerations, lacerations and destruction of the endocardium.

The study of predictors of the development of arrhythmia in elderly age people with IHD is an important task requiring the thorough investigation. The presence of late potentials of ventricles (LPV) is considered presently as one of the most highly informative parameters indicating an electrical inhomogeneity of myocardium, which would result in cardiac rhythm disturbance. The presence of early, late ventricle potentials as well as a dispersion of QT, QRS and T intervals are believed to be the predictors of arrhythmia along with other indices. The study focused on determining a frequency of such predictors among patients of 60-74 y.o. with various clinical picture of IHD. 300 patients were observed: 120 of them with IHD, 100--additionally having essential hypertension, 60--PICS (postinfarction cardiosclerosis), 20--HF. 20 people aged 60-89 formed the control group. The registration of LPV, EPV as well as QT, QRS and T dispersion was carried out by means of Megacart electrocardiograph (produced by "Siemens" company, Germany). The findings are the following: 48 % of the patients with IHD were found with LPV, 33%--with EPV (early potentials of ventricles). LPV is also more frequently met in the patients with IHD complicated with heart failure (HF) and hypertension; dispersion of QRS and T is for sure higher in patients with IHD and HF.

We carried out a multicenter controlled study of case histories of patients with schizophrenia and acute myocardial infarction (AMI) or postinfarction cardiosclerosis (PIC) from cardiological (n=44), psychosomatic (n=19) and psychiatric (n=23) hospitals was. In hospital mortality, ischemic heart disease (IHD) risk factors, peculiarities of IHD course, antipsychotic therapy were analyzed. Elevation of in hospital mortality related to PIC and its complications was revealed in somatopsychiatric (21% vs 1.26%; p<0.05) and psychiatric (29% vs 1.26%; p<0.05) hospitals. Hypercholesterolemia, excess weight in patients with schizophrenia were met more rarely (36, 32, 9, 21%, 16, 0% vs 61, 45%, respectively; p<0.05) while diabetes mellitus (5, 5, 9% vs 15%, respectively; p>0.05), arterial hypertension (89, 84, 45% vs 77%, respectively; p>0.05) - with same frequency as in comparison group. Patients with schizophrenia do not differ from persons not suffering from this psychiatric disease by proportion of patients with AMI (39, 47, 49% vs 43%; p>0.05) and PIC (73, 74, 61% vs 73%; p>0.05). Probability of effect of inadequate body weight and psychotherapy with phenothiazine derivatives and antiparkinsonian cholinolytic medications on elevation of mortality of patients with IHD and schizophrenia is discussed.
