With the objective of evaluating the clinical usefulness of a new immunologic method (Merck-1-Test CK-MB), in the determination of the CK-MB activity, 48 patients admitted to the Coronary Unit for
angina pectoris
were studied. Samples of blood were gathered upon admission and every 4 hours for 48-72 hours, determining in each one of them the total CPK, SGOT,
LDH
, and CK-MB; electrocardiograms (ECG) were taken and all possible causes for the increase in the enzymatic activity were recorded. Results were analyzed in order to study the following aspects: in the patients in which an acute myocardial infarction was diagnosed the CK-MB activity was studied, also the relation of CK-MB to the remaining parameters, each parameter's sensitivity and specificity and the relationship of the CK-MB to the prognosis of the patients. The usefulness of CF-MB in the differential diagnosis of myocardial necrosis and variations in the total CKP curve in the clinical course of acute myocardial infarction unrelated to myocardial necrosis were evaluated too. The following conclusions were drawn from the analysis of the data. The immunological method has the advantages of its sensitivity and easily and quickly performance (15 minutes), but it has the disadvantage that it detects CK-BB (elevated in cebrovascular disorders). Twenty-four hours after the onset of symptoms, the negativity of CK-MB does not exclude the diagnosis of a myocardial necrosis. CK-MB is more sensitive than total CPK in diagnosing the extent of the area of necrosis. CK-MB is very specific for myocardial necrosis but less sensitive than other parameters. A positive CK-MB upon the patient's admission confirmed the diagnosis of necrosis in 60 percent of the cases, but in 18 percent error was induced because of false positives. CK-MB permitted confirmations of the diagnosis of myocardial infarction in 33 percent of cases in which there was only a suggestion of necrosis by the ECG. The variation in the curve of total CPK in the course of an acute myocardial infarction is subjected to such a great number of factors intercurrent with time, that caution should be exercised in trying to relate a specific elevation of total CPK to an unsuccessful maneuver or to a possible extension of the area of necrosis.

210 male patients hospitalized for cardiac rehabilitation have been studied. As a result of age matching the sample was reduced to 190 patients: 72 patients with myocardial infarction, 90 patients with functional cardiovascular diseases, and 28 patients with
angina pectoris
. At the beginning and at the end of the 4 to 6 week rehabilitation program total lipids, cholesterol, triglycerides, phosphatides, GOT, GPT,
LDH
, HBDH, cholinesterase, aldolase, blood sugar, creatinine, electrolytes, hemoglobin, erythrocytes, leukozytes, and catecholamines were measured. In addition to the statistical comparison of the three groups and their specific change patterns, effects of body weight reduction and improvement of physical fitness were analyzed. The decrease of lipids is especially associated with weight reduction, whereas the decrease of enzyme activity and electrolyte concentration is accompanied as well with weight reduction as with the improvement of physical fitness.

Survival of 312 patients with acute myocardial infarction was studied from data collected during the first 48 h in the coronary care unit. Only patients with recent onset of symptoms (48 h), with a 48-h survival, and with evidence of myocardial infarction, were selected. Mortality rate at 1 mth was 15.3% and 24.6% at 6. The following factors were significant for poor survival: increasing age, female sex, diabetes, previous
angina
, low blood pressure on admission and at the 48th h low average value and the lowest observed value of blood pressure, clinical and radiological left ventricular failure, high level of
LDH
, increased urea and leukocytosis. Among ECG data, the presence of signs related to extent of infarction, anterior as compared to inferior location, antero-lateral as compared to anterior, QRS frontal axis deviation, absence of sinus rhythm, sinus tachycardia, tachyarrhythmias with wide QRS complex, right bundle branch block, 3rd-degree AV block with wide QRS complex, was associated with significantly worse survival than the absence of these signs. A multivariate analysis of the 42 most significant data, assuming linear regression, was used to establish a discriminant prognostic index. Using this index, survival was predicted correctly in 90.2% of patients at 1 mth and 85.7% at 6 mth. Thus prognosis can be established in nonclear-cut groups of patients with myocardial infarction (severe and benign forms being excluded by criteria) from simple clinical data.

Short-term results of aggressive surgical management were compared with results of medical management in forty-three patients with preinfarction
angina
admitted to the coronary-care unit (CCU) over an 18 month period. These patients were selected from 1,609 consecutive admissions to the CCU because they met strict criteria for preinfarction
angina
: severe chest pain at rest, ST-segment elevation or depression during pain which subsided rapidly after cessation of pain, and normal serum enzymes (CPK, SGOT, and
LDH
). Twenty-three patients had coronary angiography, done with operating room and pump standby. One patient, who had total occlusion of the left main coronary artery, died during the study. Twenty-one of the remaining patients were considered surgical candidates, and were treated immediately after angiography with 1 to 3 vein bypass grafts. There was one late postoperative death and, of the 20 survivors, 2 had ECG evidence of acute myocardial infarction and one had mild
angina
at time of discharge. In contrast, of the 21 patients treated medically, 13 sustained acute MI, resulting in 8 instances of congestive heart failure and 4 cases of ventricular fibrillation. Four patients died in cardiogenic shock. With the use of rigid criteria, a small subgroup of patients with variant
angina
at high risk of developing AMI has been identified and categorized as having preinfarction
angina
. Our experience suggests that aggressive surgery immediately following coronary angiography offers a lower incidence of MI, morbidity, and death than does medical management.

The reliability of serum MM3/MM1 ratio as a marker for AMI was evaluated in 81 consecutive coronary-care admission. Of these, 62 patients were diagnosed as definite infarction and 19 patients as
angina
, using WHO criteria. The MM3/MM1 ratio in the admission serum sample was 1.85 +/- 2.01 in 62 patients with definite infarction; in contrast, the MM3/MM1 ratio was 0.24 +/- 0.14 in 19 patients with
angina
(P less than 0.01 for MI group vs
angina
group). Among the AMI patients admitted within 12 h after onset, the diagnostic accuracy of the ratio MM3/MM1 was higher than CK, CK-MB,
LDH
, LD1/LD2 and GOT and similar to Mb in the initial serum samples. It seems that the MM3/MM1 ratio was a better enzyme marker than the others in the early stage of AMI, especially before 12 h.

In 5 elderly patients, an abnormally high occurrence of some symptoms was noted during dialysis. All patients were dialyzed with biocompatible membranes, bicarbonate dialysate, and a blood flow of 250 to 300 ml/min by a single needle system, on a fistula 14 Gauge catheter-needle. These symptoms were: 1) "angina," resistant to O2 and nitrates, with biochemical stigmata of infarction, but without electrocardiogram (ECG) localization; 2) intractable persistent hypotension, not hypovolemic, lasting 1 or 2 days; 3) esophagal spasms, with inability to swallow solid food. Because we knew that these symptoms were compatible with hemolysis (biochemically proven by the increase in serum
LDH
during dialysis and by a fall in haptoglobin) due to red cell fragmentation (RCF), we switched these patients from fistula dialysis (A) to central catheter dialysis (B), with the same apperture, blood flow, etc. The total number of sessions of A versus B were 512 and 891; the mean
LDH
ratios (serum
LDH
postdialysis divided by predialysis) were 1.8 and 1.0 (= no RCF);
angina
events were 132 (26%) for A, and 25 (3%) for B; persistent hypotension was seen 37 (7%) times in A and 5 (0.6%) times in B; esophagal spasms were noted 65 (13%) times for A, and 0 times for B. This clinical improvement was so overwhelming that 3 patients refused to be dialyzed again using their well functioning fistulae. This study also proved the need for a better designed and manufactured peripheral dialysis catheter-needle.

The detection rate was examined for ECG (EchoECG) equivalents of clinical coronary heart disease (CHD) forms, such as
angina pectoris
, focal myocardial dystrophy, small and large myocardial infarction, at various levels of the peak activity of blood creatine phosphokinase in the acute period of the disease. A series of investigations revealed in the acute period the time when myoglobin, CPK, CPK MB, AST, and
LDH
attained their maximal blood content, which were directly related to the molecular weight of proteins. The findings allowed the author to consider a relationship between the values obtained by diagnostic techniques and the time course of an infarct process, the mass of ischemic necrosis and its topography in the myocardium.

The effects of i.v. nitroglycerin were studied by ECG and enzymatically in 16 patients (mean age 57.9 +/- 1.4 years) (NTG) in comparison with a control lot (c) of 17 patients (mean age 62.7 +/- 2.1 years) treated with dipyridamole and/or nifedipine (N), admitted in the first 4-10 hours after the onset of the first symptoms. The patients with heart failure and those with Q waves and CPK or
LDH
values greater than 2 x n were not admitted. NTG was administered in doses of 20 micrograms--60 microgram/hour for 24-96 hours and systolic AT (s) was kept under 10% of the basic values but not under 100 mmHg. Myocardial infarction appeared in 9 N-treated patients (54.86%) and 11 controls (58.25%) (p = 0.07). The size of myocardial necrosis was reduced in the N-treated patients. Peak serum CPK levels had considerably less increases in N (from 72.9 U to 73.4 U) (p greater than 00.5) versus C from 34.2 U to 364.5 U) (p less than 0.001). The sum of segmentary depression failed from 9.13 mm to 3.19 mm (p less than 0.05) in N, whereas in C the decrease was not significant (6.12 mm as against 9.38 mm; p greater than 0.05). The evolution was severe in C, as the
angina
crises (14 cases versus 2 cases, p less than 0.01) and the extension of the infarction (8 cases versus, 0; p 0.05) less than 0.05) appeared more frequently than in N. Only two patients in C died (p less than 0.05). Therefore, i.v. NTG administration in small doses in acute myocardial infarction leads to immediate disappearance of the
anginal pain
, lowers the extent of the myocardial necrosis and improves the clinical evolution.

Three paroxysmal episodes of ST-segment elevation in lead II of ECG were observed during bullectomy and chest closing under epidural anesthesia supplemented with enflurane in compressed air in a patient who had history of variant
angina
with 50% obstruction of right coronary artery. The first and the third episodes were followed by ventricular tachycardia, complete A-V block and hypotension. These attacks were preceded by decreases in heart rate and blood pressure. It was suspected that coronary artery spasm developed with increased vagal tone under thoracic epidural block. The first and the second attacks were successfully treated with intravenous injection of nitroglycerin and lidocaine. The third attack needed additional treatments which included intravenous administrations of atropine, epinephrine, isoproterenol and phenylephrine and direct heart massage through the thoracic incision. Postoperative serial examinations of ECG showed inverted T in lead V1-V4, and serum enzymes (GOT, GPT,
LDH
, CPK, CPK-MB) were elevated. However ratio of CPK-MB to total CPK was only 1.5%. The patient was discharged two weeks after the operation with normal ECG and serum enzymes. It is speculated that coronary artery spasm was induced by hypotension and vagal stimulation under epidural anesthesia which blocks cardiac sympathetic nerves.

One hundred and twenty-three patients underwent combined valve and coronary artery bypass surgery, between 1974 and 1985. Seventy patients had aortic valve replacement, 53 had mitral valve replacement; 63.4% were male and 45% were over 60 years (mean 59 +/- 2 years). Ischaemic cardiac arrest was used in 21 patients (Group I), cold crystalloid cardioplegia in 51 (Group II), and cold blood cardioplegia in 51 (Group III). Group III had a greater number of patients with poor preoperative functional status and left ventricular function. Early mortality was 19%, 17.6% and 11.7% in Groups I, II and III respectively (NS), and was not influenced by patients age, number of vessels with critical coronary artery disease and the type of the valve procedure. There was a significant decrease in the release of
LDH
and AST in Group III when compared with Group II (p less than 0.02 and p less than 0.01) respectively. The linearized rate of recurrence of
angina
(% per patient year) was 0.4, 0.95 and 0.07; and late mortality (% per 100 years) was 5.8, 3.2 and 2.6 in Groups I, II and III respectively. Patient survival and the quality of life has been improved since the introduction of cold blood cardioplegic protection.
