The significance of silent myocardial ischemia detected by dipyridamole perfusion scintigraphy was evaluated in 80 patients with stable angina and reversible defects (RD) but no infarction. The patients were divided into two groups: 26 patients with silent RD (62 +/- 7 years) and 54 patients with painful RD (65 +/- 7 years). Coronary risk factors, extent of coronary lesions, localization and degree of RD, and prognosis were compared. There was no significant difference in the incidence of coronary risk factors between these two groups, except for hyperlipidemia which was less frequently observed in patients with silent RD than in those with painful RD (8% vs 41%, p < 0.01). Coronary angiography revealed a higher prevalence of insignificant lesions or single vessel disease in patients with silent RD than in those with painful RD (73% vs 39%, p < 0.05). Dipyridamole perfusion scintigraphy revealed a lower degree of RD in patients with silent RD than in those with painful RD (4.4 +/- 3.3 vs 9.0 +/- 4.1 segments, p < 0.05), though there was no significant difference in the localization of RD between these two groups. Treadmill stress testing revealed a lower incidence of chest pain in patients with silent RD than in those with painful RD (26% vs 65%, p < 0.05), despite the mean exercise-duration being significantly longer in the former than in the latter (5.5 +/- 1.7 vs 3.9 +/- 1.7 min, p < 0.05). There was no significant correlation between the late peak serum ML-1 level and LV volume, and the size and motion of infarcted areas in group B.(ABSTRACT TRUNCATED AT 250 WORDS)

Recent apheresis therapy is developing day by day. Now we can say that we do not achieve suitable treatment without an apheresis technology. Acute and chronic renal failure, severe hepatic failure, acute necrotic pancreatitis and MOS are not able to treat without haemodialysis (HD), haemofiltration (HF) and plasma exchange (PE). Immunomodulation for immune complex diseases and removing of pathologic antibodies are controlled by this technique. In the near future, it will play an important role for controlling of xenotransplantation. LDL apheresis for hyperlipidemia is very effective in cleaning the blood, and the prevention of ASO, angina syndrome and coronary disease is discussed. LAK therapy and immune therapy using apheresis technique have been effective for cancer and it will be developed moreover. Lastly, apheresis used to prevent aging is the music of the future.

Coronary artery calcification (CAC) was easily demonstrated by plain CT-scan. The aim of this study was to clarify the clinical significance of CAC in cardiovascular diseases. The subjects were 90 patients with ischemic heart disease (30 myocardial infarction, 50 exertional angina pectoris and 10 variant form of angina pectoris; 46 males and 44 females, 68 +/- 10 y/o) and 50 patients without ischemic heart diseases (30 hypertension, 10 arrhythmia, 3 valvular disease, 2 cardiomyopathy, 2 congenital heart disease and 3 others; 25 males and 25 females 65 +/- 9 y/o). CAC and calcification of thoracic aorta were evaluated by plain CT-scan (1 second scan time and 5 mm slice). The relationship between CAC and other clinical features (age, sex, hypertension, diabetes mellitus, hyperlipidemia, smoking, resting ECG, exercise stress ECG, aortic calcification and optic fundi) were studied. CAC were seen more frequently in patients with ischemic heart disease (63%), old age (67%), aortic calcification (70%) and positive exercise testing (64%). On the other hand, CAC were rare in variant angina (30%). In younger patients (under 70 y/o), CAC were seen more frequently in diabetic patients. But, in older patients, CAC were frequently in those with hyperlipidemia. These results suggested that CAC was associated with not only systemic arteriosclerosis, but also ischemic heart disease, except vasospastic angina. The prognostic value of CAC would be studied later.

The clinical and echocardiographic variables related to postinfarction angina were evaluated in 54 patients with acute myocardial infarction. All patients underwent 2D echocardiography at 2-3 weeks after infarction. Wall motion analysis was quantified with a wall motion score index (WMSI) based on 16 left ventricular wall segments. Among the 54 patients with acute myocardial infarction 23 (42.6%) had early postinfarction angina. Multiple regression analysis demonstrated no significant difference between the patients with and without postinfarction angina in age, sex, location of infarction, Killip classification, previous angina, hypertension, hyperlipidemia, diabetes mellitus, creatine kinase level and left ventricular ejection fraction. In comparison with patients without postinfarction angina, patients with postinfarction angina had higher WMSI. It indicates that postinfarction angina appears to be related more to myocardial ischemia rather than to the infarct of myocardium.

Although myocardial ischemia causes angina pectoris, angina and the severity of coronary artery stenosis in individuals do not correlate. However, changes in anginal status over time correlated with changes in the severity of coronary artery stenosis as determined by repeated coronary arteriograms has not been previously studied. Coronary arteriograms, done both at entry into the Program on the Surgical Control of the Hyperlipidemias (POSCH) and 3 years later, were blindly graded for changes in overall severity of coronary artery stenosis according to protocol by the POSCH Arteriography Review Committee. Arteriographic and clinical data from 376 control subjects (347 men, 29 women) were analyzed. There was no statistically significant relation over a long-term (3 year) period between the absence, presence, development, or disappearance of angina pectoris and changes in coronary artery stenosis severity as determined by coronary arteriography.

The prevalence of and risk factors for varicose veins (VV) were studied in elderly persons over 60 years of age who had visited the Tonya and Farabi Hospitals in Trabzon, a city in northeastern Turkey. VV were defined as dilated, tortuous and elongated veins of the lower extremities and were classified into four types. The total prevalence of VV was 36.7% (14.6% in males and 22.1% in females). Segment type varices were observed in 16.5%, saphenous type in 5.6%, reticular type in 4.7%, web type in 2.3%, and combined types in 7.5%. The prevalence of VV increased with age and was greater among those with a family history of the condition in 154 of 312 patients with VV (49.4%). Other factors, such as congestive heart failure, angina pectoris, hypertension, cigarette smoking, diabetes mellitus, height, weight, obesity, or hyperlipidemia, were not found to be associated with the prevalence of VV. However, the factors of age, work posture and childbirth did show an association with prevalence, as reported by others.

The sixteen-lead ECG chest wall mapping was used to investigate the significance of inverted U waves during exercise in diagnosing occult coronary artery disease (CAD) in asymptomatic high-risk subjects. For this purpose 100 patients with various types of hyperlipidemia and 33 patients with diabetes mellitus were studied. None of these patients had a history of angina pectoris or myocardial infarction and all had normal resting ECG. Exercise was carried out on a bicycle ergometer to an end point, and ECG recordings were made from all sixteen chest leads. Inverted U waves developed during the early minutes of exercise in 8 patients (6 hyperlipidemics and 2 diabetics), indicating disease in 11 coronary artery territories (7 in the left anterior descending/diagonal coronary artery, 3 in the circumflex, and 1 in the right coronary artery territories). Subsequent coronary arteriography confirmed the territorial distribution of the inverted U waves in all the cases. Following coronary artery bypass grafting in 2 of these patients no U wave inversion developed during stress testing. It is concluded that exercise-induced inverted U wave is a reliable indicator of silent myocardial ischemia due to occult CAD in asymptomatic high-risk subjects. Its distribution on the ECG chest wall map is highly predictive of significant disease in the individual coronary artery territory. The disappearance of this ECG sign following myocardial revascularization is a further proof of its myocardial ischemic origin.

We have reviewed 15 cases of carotid artery stenosis in the neck, consisting of 11 patients with cerebral ischemia and 4 asymptomatic patients, in relation to associated coronary heart disease. The 15 patients had systemic complications, including hypertension in 87%, diabetes mellitus in 40% and hyperlipidemia in 57%. Systemic vascular complications other than coronary heart disease were present in 27% of the patients. Three of the 15 patients had a history of ischemic heart disease and had been treated by cardiologists. One patient developed angina pectoris on the second day of a cerebral ischemic attack. Coronary angiography (CAG) and simultaneous cerebral angiography following carotid endartectomy (CEA) were performed 4 of the remaining 12 patients, who had symptoms or history of ischemic heart attacks. Three of these four patients had stenotic lesions in their coronary arteries. Another one patient among the remaining 8 developed angina pectoris one year after undergoing CEA. This patient had 3-vessel coronary artery disease. These findings suggest that a strong correlation between stenotic lesions of the carotid arteries in the neck and coronary heart disease, with or without episodes of ischemic heart disease. CAG should be strongly recommended in such patients to assess the severity of complicating ischemic heart disease and to improve the prognosis following CEA.

Sixty-two elderly men with coronary heart disease (CHD), 54 of them also suffering from hyperlipidemia, were treated with a new oral androgenic preparation (Andriol) through crossover study. The results showed that after oral Andriol administration for one month, serum estradiol/testosterone (E2/T) ratio was reduced, (P < 0.05) symptom of angina pectoris was relieved (total effective rate, 77.4%), signs of myocardial ischemia in ECG and Holter monitoring were improved (total effective rate, 68.8% and 75% respectively), serum total cholesterol (TC) and triglyceride (TG) levels were reduced dramatically (both P < 0.001) and the serum level of high density lipoprotein cholesterol (HDL-ch) was increased (P < 0.05), but the blood levels of apolipoprotein-AI (APO-AI) and B (APO-B) remained unchanged. No significant side effect of Andriol was observed.

The study was made of gemfibrozil tolerance and effectivity against atherosclerosis and in correction of lipid metabolism in 20 patients with hyperlipidemia. (11 males and 9 females, a mean age 51 +/- 3.1 years). The assessment of the treatment efficacy was performed clinically, biochemically, using bicycle ergometry exercise. Eight weeks of gemfibrozil treatment in a dose 12-1.8 g/day produced a hypolipidemic effect in 90% of the patients which were mostly of IIb and IV genotypes. The highest efficacy was reported in lowering triglycerides, VLDL cholesterol. In less extent the drug reduced LDL cholesterol. Some of the patients became hypolipidemic by HDL cholesterol. It is concluded that in hyperlipidemic patients gemfibrozil improves the running of atherosclerosis without the effect on angina pectoris.
