The purpose of this study was to determine whether global and segmental left ventricle (LV) systolic function, assessed by exercise echocardiography (EE), improves after PTCA in patients without previous myocardial infarction (MI) and after infarction and angioplasty of infarct related coronary artery. 32 patients without MI and 35 patients with previous (4 +/- 3 months) MI were examined before PTCA (percutaneous transluminal coronary angioplasty), 3-5 days after successful elective PTCA and 6 months later with EE (modified Bruce protocol). LV ejection fraction (EF) and wall motion score index (WMSI) at the baseline and immediately after exercise were assessed. Following angioplasty (after 3-5 days and 6 months later), exercise duration was significantly (p < 0.001) increased in both groups of patients. Resting EF and WMSI did not change after angioplasty of infarct-related artery, but in patients without prior MI resting EF increased (p < 0.001) after PTCA in comparison with pre-PTCA values. Significant improvement of exercise EF and WMSI were observed in both groups of patients. In 25 of 35 patients with old MI wall motion improvement in the infarcted region after PTCA was observed. Twenty of these 25 patients developed exercise-induced akinesia in this area during pre-PTCA EE. Among 10 patients without improvement of the regional contractility were 9 after type Q-wave infarction and only 2 developed angina during EE. These data demonstrate improvement in global and regional systolic LV function and better exercise tolerance following successful PTCA both in patients without prior MI and with old MI after angioplasty of a stenosis in an infarct-related coronary artery.(ABSTRACT TRUNCATED AT 250 WORDS)

One of the causes of artery spasm in patients with the variant angina could be disordered interaction between the vasodilating action of endothelial derived relaxing factor and vasospastic action of endothelin. The aim of this study is to see whether endothelin participates in etiopathogenesis of the coronary artery spasms in patients with variant angina. The survey was made in 39 patients with variant angina with or without history of myocardial infarction. The control group consisted of 26 patients with chronic stable angina pectoris and 20 healthy persons of the same age and sex as patients with variant angina. One hour before examination a venous catheter had been inserted. Then Tris (pH = 10.5) was given by 5 minutes intravenous infusion followed by hyperventilation, during which the person under test was breathing for 5 minutes with a frequency of 40/min. Endothelin 1 and 2 plasma level was determined immediately before the hyperventilation test, immediately after the termination of the test and 6 minutes later. The appearing of coronary artery spasm was detected on continuous electrocardiographic monitoring. Endothelin 1 and 2 level in plasma was determined with radioimmunologic method ("Endothelin 1.2 high sensitivity (125I) assay system" manufactured in Amersham). The study showed clinical and electrocardiographic symptoms of coronary artery spasm after hyperventilation and Tris buffer infusion in all 39 patients with variant angina--but neither in those with chronic stable angina pectoris nor in healthy persons. Patients with variant angina had higher plasma endothelin 1 and 2 levels after hyperventilation and Tris infusion than those with chronic stable angina pectoris.(ABSTRACT TRUNCATED AT 250 WORDS)

In 1989-1990, 892 patients with ischemic heart disease were treated at the III Department of Cardiology in Katowice-Ochojec. Aortocoronary bypass was performed in 51 (5.7%) of these patients. Thirty five out of these patients were followed-up for 24 months after surgery. They reported to the hospital for evaluation after 3, 6, 12 and 14 months following a discharge. Efficiency of revascularization was checked with physical examination, and non-invasive tests such as electrocardiography, echocardiography and exercise tolerance testing. Diastolic and symbolic functioning of left and right ventricle was assessed separately. All patients suffered from anginal pain before surgery whereas 85% of operated patients were free from pain. No correlation between incomplete revascularization and recurrence of the anginal pain was noted. Surgery produced an increase in exercise tolerance and maximal load. No significant improvement in the right ventricle was seen during a 2-year follow-up. In the group of patients without previous myocardial infarction measured parameters of cardiac ventricles functioning were better than those in patients who had myocardial infarction. Therefore, the former are better candidates to coronary vessels revascularization.

This study aimed at evaluating predictive value of exercise tests in case of left coronary artery stenosis. The study involved 57 patients with left coronary artery stenosis, including 10 patients with isolated left main stenosis (group X), and 47 patients with left coronary artery stenosis and multivessel involvement (group Y). Unstable angina was staged according to Booth et al. classification as type I or II. Exercise tests were performed according to Bruce's protocol. Unstable angina of type I was diagnosed in 51 (89%) patients, and type II in 6 (11%) patients. Electrocardiographic evidence of myocardial ischemia both et rest and anginal pain was seen in 46 (80%) patients. Electrocardiographic recording was within normal limits in 11 (20%) patients at rest. Clinical and ECG improvement was seen in 38 (66%) patients. Exercise tests in all of these patients were positive at low load work--mean 50 W. The obtained results suggest that patients with left coronary stenosis constitute heterogenous group. Therefore, prediction of the left main stenosis on the clinical ground alone is impossible. Exercise tests producing positive results at low load indicate with high probability critical multivessel lesions and/or left main stenosis in such patients.

The studies aimed at assessing the kind and the incidence of the complications of monocytic angina in childhood. In 7 out of 343 hospitalized children neurological disorders were found, thrombocytopenia was seen in 5 cases, pneumonia in 3 cases, bronchitis in 12 cases, and AV block in 3 cases. The most frequent complication of monocytic angina was respiratory tract obturation (6.4% of cases).

The aim of this study was to estimate coincidence of coronary artery disease (CAD) and rheumatic mitral valve disease in 264 patients treated in the National Institute of Cardiology (1976-1990). Severity of stenoses on coronary angiography with respect to age, sex, symptoms and risk factors were also estimated. Stenoses over 70% of artery lumen in relation to artery diameter before lesion and over 50% for left main coronary artery were stated as severe. There were 180 (68%) females and 84 (32%) males in the studied group; mean age was 52.5 year. Patients were divided into two groups: with angina--126 pts and without CAD symptoms--138 pts. 8 females (4%) had severe stenoses and 45 (25%) non-severe. Respectively 14 males (16.7%) had severe stenoses and 14 non-severe. Severe lesions were present in a group of females older than 50 years and in a group of males older than 45 years. Both in group with or without angina prevalence of coronary artery lesions was similar. Sensitivity and specificity of CAD clinical symptoms was low (less than 50%). Significantly more risk factors were present in pts with coronary stenoses than in pts free of CAD. No correlation between high pulmonary artery pressure and angina in patients without coronary stenoses occurred.

Death rate due to myocardial infarction shows constantly growing tendency, especially in young subjects. This fact is even referred to as overmortality of young and middle-aged men. The aim of the present study was to evaluate certain clinical elements of myocardial infarction in young subjects. Out of 668 patients with acute myocardial infarction treated at the I Cardiac Department in Cracow from 1979 to 1988 a group of 102 patients (5 women, 97 men) below 45 years of age (mean = 40) was selected. The control group consisted of 241 patients with myocardial infarction, including 146 men and 98 women over 65 years of age (mean = 73). The following clinical date were analyzed: sex, presence of retrosternal pain and its aggravation, time from the onset of pain to hospitalization, anginal pain preceding the infarction and such complication as sudden cardiac arrest, pulmonary edema, cardiogenic shock, in-hospital deaths. The infarction in patients below 45 years of age occurred mainly in men. They experienced retrosternal pain more frequently than the elderly patients. It did not, however, affect the time of hospitalization. Serious complications of the infarction developed less frequently in younger patients and the in-hospital mortality was also lower in that group.

Exercise tolerance was tested with cycloergometer, and ECG recorded in 33 patients with exercise-induced angina pectoris. Patients' age ranged from 36 to 65 years. Tests were performed prior to and after a single oral dose 2 mg of molsidomine or placebo. Molsidomine reduced the number of patients with exercise-induced coronary pain from 33 to 25, i.e. from 84.5% to 27.27%. Pain-free period was significantly longer in patients given molsidomine whereas postexercise pain and total duration of the coronary pain were significantly shorter. Total work was markedly higher, and maximum ST depression in ECG record following exercise was significantly lower than the values noted prior to molsidomine administration and in placebo group. Heart rates both resting and during exercise did not differ in molsidomine and placebo groups. Molsidomine may be considered as an effective drug preventing exercise-induced anginal pain within 1 hour after administration.

The frequence of ischemic heart disease occurring increases 2-3 fold in postmenopausal period. It is a result of serum lipid profile changes. Estrogenotherapy restores correct lipid relations and protect coronary vessels in this way, preventing stenocardia and cardiac infarcts. Divergent opinions coexist with including progestogens to estrogen replacement therapy. However a view that well selected doses and kind of hormone effectively enhance serum HDL level, begins to prevail.

Immediate effect of PTCA and CABG for unstable angina then followed-up for PTCA and CABG several years are analyzed in 112 patients selected out of 204 unstable angina patients hospitalized from 1990 to 1991. Fifty three patients, aged 25-68 (mean 51) were assigned to PTCA, fifty nine aged 33-69 (mean 53) were subjected to CABG. Both groups comprised of 72% and 83% males respectively. Nine patients with de novo angina, forty with crescendo angina and four with prolonged stenocardia were assigned to PTCA. 28% of patients have had myocardial infarction. Nine patients with de novo angina and fifty with crescendo angina were assigned to CABG. 56% of them have had myocardial infarction. Left ventricular ejection fraction (LVEF) less than 40% was found in 8 (15%) PTCA patients and in 18 (31%) patients who underwent CABG. Full revascularization was achieved in 38 (73%) patients treated with PTCA and 46 (78%) CABG patients. In 9/17% patients only critical stenosis in multivessel disease was subjected to PTCA. Four cases of myocardial infarction underwent intervention and all of these patients died: one (2%) after PTCA, and three (5%) after CABG. Fifty two patients after PTCA and fifty six after CABG were followed for one to four (mean 3) years. Thirty one percent of patients after PTCA and 41% after CABG were asymptomatic, 61% and 54% respectively had little to moderate symptoms. Left ventricular systolic function improved in most patients, predominantly in those with LVEF less than 40% (p < 0.05) treated with PTCA. Hospitalization due to anginal pain was needed in 46% of patients after PTCA and 15% after CABG (p < 0.05). Coronary artery restenosis after PTCA was successfully treated with re-PTCA or CABG in 9 (17%) patients. Venous graft stenoses were dilated in two cases. Myocardial infarction occurred in 3 (6%) patients after PTCA and 2 (4%) patients after CABG. One patient died after redilatation CABG treated patients required nonsignificantly less antianginal drugs. Four week survival rate in PTCA group and CABG group was 98% and 95% respectively; three year survival was 95% in both groups. We conclude, that unstable angina patients requiring either angioplasty or surgery may expect good procedural and long term prognosis. Remarkably good results may be expected in successfully revascularised patients with low ejection fraction.
