[Attitude of district internists to the problem of secondary prevention of ischemic heart disease (results of a special questionnaire survey)].

Attitude of district internists to the realization of a concept of secondary prevention (SP) of ischemic heart disease was studied in one of large cities in Russia. Among preparations most necessary for SP the following were named: b-blockers (79.5%), angiotensin converting enzyme inhibitors (49.3%), antiaggregants (43.8%), hypolipidemic drugs (13.7%), nitrates (63%), biologically active supplements, phyto-preparations, metabolic drugs, and glycosides (3-5% each). However actually prescribed drugs were b-blockers (100%), nitrates (96%), angiotensin converting enzyme inhibitors (89%), calcium antagonists (87%), antiaggregants (83%), cardiac glycosides (66%), vitamins (39%). Average doses of drugs were low: 21.7, 47.4 and 35.5% of possible maximal doses for statins, angiotensin converting enzyme inhibitors, and beta-blockers, respectively. Nondrug measures were used "rarely" and "often" by 26 and 74% of physicians, respectively. Only 18% of physicians directed their patients to corresponding specialists. Recommendations were mostly formal, without explanation of goals, methods and specific features of recommended measures. Moreover their prescription by physician was determined largely by subjective factors: availability of sufficient time (50%), cultural level of a patient (79%), patient's own initiative (33%), physician's personal attitude to a patient (21%).

[Exercise in outpatient complex rehabilitation and secondary prophylaxis in patients with ischemic heart disease after acute coronary events (a cooperative trial in Russia)].

AIM: To assess efficacy of early and long-term exercise in patients with ischemic heart disease (IHD) after acute coronary events (acute myocardial infarction--AMI, unstable angina--UA, coronary artery bypass grafting--CABG) in wide outpatient medical practice of Russia. MATERIAL AND METHODS: Three to eight weeks after the acute coronary event (ACE) 373 patients from different clinics of RF regions were randomized into two groups: the study group (n = 188) and a control one (n = 185). Both groups received standard therapy, the study group performed also a special exercise program (moderate exercise for maximum 1 hour 3 times a week for a year). The efficacy of the treatment was assessed by clinical, device and biochemical findings during 6-month follow-up. RESULTS: Physical work capacity, total amount of performed work (PW) in stress test rose in the study group by 26.5% (p < 0.01) and 59.4% (p < 0.01), respectively; HRmax and BPSmax x HRmax increased by 6.4 and 9.8%, respectively, p < 0.01); PW/Hrpeak rose by 48.6% (p < 0.01), PW/DP peak--by 45.9% (p < 0.01). Left ventricular ejection fraction increased by 5.6% (p < 0.05), LV stroke volume--by 3.4% (p < 0.05). In 6 months, controls demonstrated a 4.7% (p < 0.05) rise in HDLP cholesterol, total cholesterol lowered in the study group by 6.4% (p < 0.01), body mass index--by 1.9%, number of anginal attacks--by 0.9%. CONCLUSION: The proposed exercise program is effective and can be applied in outpatients after acute coronary events. The program can be also used as a method of secondary prophylaxis as it lowers total cholesterol, atherogenic index and body mass index.

[Multidirectional effects of exercise of various type and intensity on lipid transport system of blood in healthy subjects and patients with coronary heart disease].

AIM: To evaluate effects of dynamic exercise (DE) and static leg exercise (SE) varying by intensity on blood serum spectrum of lipoproteins and apolipoproteins in healthy persons and patients with coronary heart disease (CHD). MATERIAL AND METHODS: Healthy 12 men and 12 CHD patients of functional class I performed bicycle DE of maximal (for age) intensity (100%), submaximal (80, 70 and 60%), SE of maximal and submaximal intensity. Blood samples were taken before the exercise, after it and 3 hours after the exercise. RESULTS: DE of high intensity (80% and higher) and SE of maximal and moderate intensity (100 and 60%, respectively) produced atherogenic changes in the blood of both healthy subjects and CHD patients: a rise in total cholesterol, LDLP cholesterol, triglycerides, apolipoprotein (apo) B and apo B/ apo AI. Moderate (60%) DE gave rise to antiatherogenic changes in the blood: a fall in lipoproteins containing apoB and a rise in concentration of apo AI both in healthy and CHD subjects. CONCLUSION: To prevent atherosclerosis by correction of atherogenic lipid disorders, CHD patients and healthy persons should do DE of moderate intensity in addition to other prophylactic measures.

[Physical activity and atherosclerosis: effect of dynamic activity of various intensity on parameters of lipid-transport system and carbohydrate metabolism in patients with coronary heart disease and type 2 diabetes].

Effect of single bout of dynamic physical exercise on parameters of lipid-transport system and carbohydrate metabolism and hormones (insulin, cortisol) in the blood was studied in patients with coronary heart disease with class I-III angina and type 2 diabetes. Intensity of exercise was limited by severity of stable effort angina and was > 95, 80 and 70% of predicted maximum in patients with class I (n=10), II (n=12) and III (n=14) angina, respectively. High intensity exercise provoked development of atherogenic dyslipidemia: elevation of levels of total cholesterol, low density lipoprotein cholesterol, triglycerides, apolipoprotein B and apolipoprotein B/A1 ratio, and lowering of levels of high density lipoprotein cholesterol and apolipoprotein A1. Patients with diabetes responded to high intensity exercise by elevation of blood glucose and insulin levels and lowering of sensitivity of tissues of the periphery to insulin (glucose/insulin ratio). On the contrary exercise of moderate intensity did not affect negatively metabolism of blood lipids and carbohydrates. Six months course of physical training in patients with diabetes (n=10) corrected exogenous atherogenic dyslipidemia and derangements of carbohydrate metabolism, which developed after acute dynamic effort of high intensity.

[Effect of long-term physical training on hemostasis in patients with coronary heart disease and non-insulin dependent diabetes].

AIM: To study effects of 6-month physical training on some parameters of hemostasis in patients with coronary heart disease and non-insulin dependent diabetes (NIDDM). RESULTS: Long-term physical training resulted in lowering of fibrinogen level and increase of fibrinolytic activity assessed as euglobulin fraction clot lysis time, while factor VII activity remained unchanged. These changes were accompanied with elevation of total and high density lipoprotein cholesterol levels without any shifts in low density lipoprotein cholesterol and triglycerides. Most pronounced positive effect physical training exerted on results of a test with standard single fat load, which was used as a model of postprandial lipemia. Serum cortisol level significantly decreased after 6-month training, especially after fat load and subsequent physical exertion. CONCLUSION: In patients with combination of coronary heart disease and NIDDM long-term physical training was associated with decreased thrombogenicity of blood.

[Exercise and nicotinic acid delayed action drug Enduracin: application in outpatient rehabilitation of patients with ischemic heart disease].

AIM: To evaluate efficacy of combined use of moderate exercise and nicotinic acid drug enduracin in patients with coronary heart disease (CHD) with moderate dyslipidemia (DE). MATERIAL AND METHODS: The effects of exercise therapy alone, enduracin alone and their combination on physical performance (PP), hemodynamics, blood lipid spectrum and clinical course of CHD were studied in 93 CHD patients with moderate DE. The results were evaluated clinically after 1-year treatment. RESULTS: Combined used of exercise and enduracin in CHD patients showed its efficacy manifesting in improvement of PP, hemodynamics at rest and exercise test, left ventricular systolic function, clinical course, reduction of DE. Enduracin + exercise appeared more efficient than their use in monotherapy. Enduracin monotherapy had a positive action on PP, arterial pressure and anginal attacks frequency. CONCLUSION: Enduracin is recommended as monotherapy and in combination with moderate exercise in outpatient rehabilitation and secondary prophylaxis of CHD patients with moderate dyslipidemia and angina pectoris to relieve myocardial ischemia under exercise, to raise PP, improve lipid composition of blood and prevent maladaptive left ventricular remodeling.

[Correlation of lipemia level after fat loading with manifestation of atherosclerosis in coronary arteries].

AIM: To examine relationships between lipemia, atherogenicity of blood lipoproteins spectrum after fat loading (FL) and severity of angiographic manifestations of coronary atherosclerosis. MATERIAL AND METHODS: The study enrolled 72 males free of ischemic heart disease (IHD)--group 1; 60 IHD patients with moderate affection of the coronary arteries (CA), i.e. maximal narrowing of one CA 50%--group 2; 107 IHD patients with severe CA affection, i.e. CA narrowing > 50%--group 3. FL was given by J. R. Patsch technique, blood sampling was made before meal, 3 and 6 hours after FL. RESULTS: It was shown that intake of food fats in IHD and IHD-free patients stimulated development of postprandial lipemia of different severity and duration. It appeared due to increased fraction of lipoproteins rich in triglycerides. In group 2 and 3 there was a definite and up to 6 hours in duration postprandial hypertriglyceridemia associated with proatherogenic deviations in lipid and protein components (LDL and HDL) by FL hour 6: growing of LDL cholesterol, apoB, apoB/apoAI and lowering of HDL cholesterol and apoAI. Patients with severe CA atherosclerosis (> 50% narrowing of three CA) had the most severe atherogenic affections in the postprandial lipoprotein spectrum. CONCLUSION: Postprandial lipemia/hypertriglyceridemia and atherogenic changes in the spectrum of lipoproteins after FL correlate directly with angiographic manifestations of coronary atherosclerosis.

[Statins: therapeutic cascade of their effects].

Concept of sequence and time of appearance of various effects of statins is presented. Apart from hypolipidemic action due to inhibition of HMG CoA reductase activity statins exert multiple pleiotropic effects. Combination of these effects makes statins a unique instrument for solution of global tasks of prevention and treatment of atherosclerosis and its consequences (ischemic heart disease etc.). Manifestations of various pleiotropic effects of statins appear after different time intervals and in most cases are not related to suppression of cholesterol synthesis in the body. First 3-4 months (first level of the statin cascade) are characterized mainly by activity of pleiotropic properties aimed at restoration of endothelial function. These properties are responsible for enhanced eNOS expression, antiischemic, antithrombotic and antiatherogenic effects. During same period of time stabilization of unstable atheromas takes place. Manifestations of second level of the cascade of statin action appear after 2 years of treatment. They are represented by retardation of progression and even partial regression of atheromatosis of coronary and peripheral arteries. Third level is signified by achievement of strategic aims of therapy with statins (in 4-5 years) -- lowering of total and cardiac mortality, reduction of number of cardiac complications. Forth level of the cascade is represented by beneficial influences on nonatherogenic cardiological phenomena and comprise hypotensive, antiarrhythmic and cardiotonic effects. And finally some other important properties of statins constitute the fifth level of the therapeutic cascade. These properties are responsible for effects directed at noncardiac pathology (prevention of diabetes, dementia, including dementia associated with Alzheimer's disease, fractures). Immunodepression, ability to reduce saturation of bile with cholesterol belong to this group of effects.

[Cooperative study "posthospital rehabilitation of patients with coronary heart disease after acute coronary incidents" conducted in moscow region.].

Effect of physical training, therapy with extended-release nicotinic acid (enduracin) or their combination on clinical course of the disease, physical working capacity, hemodynamics and blood lipids was studied in 136 patients. Patients were recruited 8-12 weeks after onset of acute coronary incident in several hospitals of Moscow region and followed up for 1 year. Type of intervention implemented in a given hospital was determined by randomization of the hospitals. Combined use of training and nicotinic acid resulted in increased physical working capacity, improved hemodynamics both at rest and during exercise, improved systolodiastolic left ventricular function and lipid profile. Combined use of interventions produced better effect than each one alone. However positive significant effect of enduracin on physical working capacity, blood pressure and frequency of angina was also demonstrated. The data obtained were used for creation of recommendations on out of hospital physical rehabilitation of this group of patients.

[Syndrome of impaired tolerance to dietary fats in coronary heart disease].

Changes of main lipid and apolipoprotein parameters of lipid transport system during postprandial hyperlipidemia were studied in subjects without (n=72) and with (n=167) overt coronary heart disease (CHD) including patients with noninsulin dependent diabetes (n=48). Tolerance to dietary fat was evaluated by oral fat load test (consumption of 639+/-7 ml of 20% cream after fast). In subjects without CHD reaction of lipid transport system to fat load was characterized by lowered total, low density lipoprotein cholesterol, apolipoprotein apo B and apo B/apo A-1 ratio, lowered or unchanged triglycerides, stable high density lipoprotein cholesterol level at the background of apo A-1 elevation by 6-th hour after load. Patients with CHD exhibited signs of impaired tolerance to dietary fat: elevation of triglycerides, apo B and apo B/apo A-1 ratio, lowering of high density lipoprotein cholesterol, increase of percentage of subfractions of small high density lipoproteins particles, increase of triglyceride content in low and high density lipoprotein fraction during 6 hours after fat load.

[Physical exercise and atherosclerosis: dynamic high intensity exercise as a factor inducing exogenous dyslipidemia].

Effect of dynamic exercise of various intensity (maximal 100% and submaximal -- 80, 70 and 60% of individual maximally tolerated work load) on blood lipids, lipo- and apolipoproteins (apo) was studied in healthy subjects and patients with coronary heart disease. Both in healthy persons and patients high intensity (100 and 80%) exercise was associated with atherogenic changes of lipid transport system: increases of levels of total and low density lipoprotein cholesterol, triglycerides, apolipoprotein B and apo B/apo-A1 ratio. On the contrary, changes after exercise of moderate (60%) intensity (lowering of apo-B containing lipoproteins in healthy subjects and patients and elevation of apo-A1 concentration in healthy subjects) were antiatherogenic.

[Physical exercise and atherosclerosis: proatherogenic effects of high and moderate intensity static exercise on blood lipid transport system].

Effects of high (100 and 80 kg) and moderate (60 kg) intensity static leg exercise on blood serum lipoproteins and apolipoproteins (apo) A1 and B were studied in healthy subjects (n=11) and patients with coronary heart disease and class I angina (n=11). Static leg exercise with loads exceeding 60 kg were associated with atherogenic changes of blood lipid transport system: elevation of levels of triglycerides, apoprotein B and apo B/A ratio both in healthy subjects and patients, and of total and low density lipoprotein cholesterol in patients. These post exercise changes were more pronounced in the presence of fasting hyperlipidemia and their severity increased with increase in duration of exercise. Static leg exercise did not increase concentration of high density lipoprotein cholesterol. For prevention of post exercise atherogenic dyslipidemia it is expedient to supplement strength training programs with dynamic exercise of moderate intensity.

[Pravastatin: pharmacological action, pleiotropic effects and efficacy in prevention of atherosclerosis].

This literature review presents data on pharmacological action of pravastatin, its lipid lowering activity, and influence on main mechanisms of atherogenesis. Beneficial pleiotropic (nonlipid) effects of pravastatin: normalization of endothelial function, antiinflammatory action, antiischemic- and antithrombotic effects are also described. These effects represent possible mechanisms of participation of pravastatin in stabilization of prone to rupture atheromatous plaques. Early and pronounced clinical efficacy of pravastatin demonstrated in trials with clinical endpoints is discussed and value of the drug for primary and secondary prevention of atherosclerosis stressed.
