The incidence, circumstances, and mechanism of development of cardiac arrest in 786 patients with myocardial infarction treated at a coronary care unit within a five-year period were studied and clinical factors are analysed with respect to success of resuscitation. One or more episodes of cardiac arrest occurred in a total of 156 patients (19.8%). Of these, 25 (16.0%) were successfully resuscitated and 131 (84.0%) died. At the clinical ward where the patients had been transferred after the acute stage, cardiac arrest occurred in additional 22 patients, of whom two were successfully resuscitated. Thus, the total number of successfully resuscitated patients throughout the five-year period was twenty-seven. The results of resuscitation were poorer in elderly patients, in those with anterior infarction, and above all in patients with severe symptoms of mechanical heart failure. Anamnestic factors (chronic angina pectoris, previous myocardial infarction, hypertension, diabetes mellitus, ischaemic disease of the lower limbs) were not significantly associated with the results of resuscitation. Primary ventricular fibrillation was the principal mechanism of cardiac arrest in 24 of the 27 patients successfully resuscitated, and its total incidence in the investigated group was 3%. The prognosis of resuscitation in patients with primary ventricular fibrillation was very good, and in all of them the resuscitation was successful and permanent.

The relation between mode of therapy and mortality rate and incidence of primary ventricular fibrillation was studied in 265 patients with diabetes mellitus and acute myocardial infarction. Sixty patients were being treated with diet only, 54 were receiving insulin and 151 were taking oral hypoglycemic agents. Fourteen patients (5.3 percent) had primary ventricular fibrillation, and all but one died. No statistically significant association was found between the incidence of primary ventricular fibrillation and the type of treatment for diabetes mellitus. Sixty-four (24.2 percent) of the 265 patients died during hospitalization. Mortality was greater among diabetic patients receiving oral therapy. However, after adjusting for age and sex, the difference among these three treatment regimens did not reach the P less than 0.05 level of significance.

During 1968-1973, 94 patients with diabetes were admitted to a coronary care unit (CCU) on 99 occasions with proved myocardial infarction. Altogether 24 of them (25-5%) died, giving an overall mortality at the time of discharge of 24% for the total admissions. This was just significantly higher than the 19% mortality recorded among non-diabetics treated in the same period but was much lower than that among diabetics treated for myocardial infarction before the advent of CCUs. No definite correlation was found between the type of anti-diabetic treatment and either mortality or the incidence of primary ventricular fibrillation. Patients with "poor" control of the diabetes before admission showed a significantly higher mortality than those with "good" control, but there was no significant difference in mortality between those with previous good control and non-diabetics.

A total of 3000 patients have had cardiac catheterization in the Andreas Gruentzig Cardiovascular Laboratory of the Emory Clinic. The purpose of this presentation is to describe the patient population selected for this procedure and our experience with this group. The concept of catheterization as an outpatient is attractive from the standpoint of cost savings and time conservation. Safety has been questioned. We have found that this technique can be performed safely in carefully selected outpatients. Careful selection attempted to eliminate those with unstable symptoms, recent myocardial infarction, severe diabetes, and renal failure. Small catheters were used to minimize the potential for bleeding. Excellent opacification of vessels was obtained with these catheters. Despite careful screening we found 2.2% had significant left main obstruction, 10.8% had triple-vessel disease, 16.0% had double-vessel disease, and 23.5% had single-vessel disease, and a similar percentage had normal coronary arteriograms. Our patients experienced ventricular fibrillation on five occasions, there were two small cerebral emboli with reversible neurologic defects, two episodes of pulmonary edema, and two episodes of severe allergic reactions. Only three patients had significant groin bleeding at home that required compression of the site. We subsequently did angioplasty on 323 patients, performed cardiac surgery (mostly coronary bypass) on 187 patients, and admitted 18.2% of the entire group. We conclude that this procedure can be done safely in this carefully designed setting and it saves time and offers cost savings. Patient selection is very important to minimize potential emergency situations and complications. The laboratory must be carefully set up and provide a close relationship with a hospital capable of attending to any unexpected emergency.

The long-term prognosis and causes of death of myocardial infarction (MI) in 62 diabetics were studied. The mean follow-up time was 6.2 years, 11 patients died in the acute stage of MI, 9 of them (81.8%) had anterior infarction and their major causes of death were ventricular fibrillation and cardiogenic shock (72.2%). 19 died in the follow-up period, 14 of them (73.68%) had inferior and anterior septal infarction; and most died of reinfarction and sudden death. The cumulative survival rate 1, 2 and 5 years after MI was 80.7%, 71.9% and 57.9%, respectively. The results suggest that treatment and prevention of MI in patients with diabetes be more attentive to prevent ventricular fibrillation and cardiogenic shock during the acute stage and in the later stage more attention should be paid to preventing reinfarction. At any stage of the disease, strict diabetic control is of vital importance.

The effects of first and second generation hypoglycemic sulfonylureas on the incidence of ventricular ectopic beats and on the duration of transitional ventricular fibrillation in the ischemic rat heart were investigated. First generation sulfonylurea compounds (tolbutamide, carbutamide and gliclazide) in 105 preparations increased, while second generation sulfonylurea compounds (glibenclamide and glipizide) in 50 preparations decreased in a dose-dependent manner both the number of ventricular ectopic beats and the duration of transitional ventricular fibrillation during the first 30 min after ligation of the left anterior descending coronary artery. Therefore, second generation sulfonylureas should be preferred in the treatment of type 2 diabetics with ischemic heart diseases, if satisfactory metabolic control cannot be achieved by a treatment regimen and diet alone.

The purpose of this study was to investigate, if besides the hypocontractility, which is the main finding in Primary Cardiomyopathy (PDC) there was some other mechanism in the development of heart failure and if this fact could influence in it's prognosis. We studied 13 patients with PDC in the hemodynamic cardiac laboratory from January 1982 to January 1988, these with systemic arterial hypertension. Coronary heart disease, myocarditis, primary valvular lesion, infiltrative disease, nephropathy, congenital heart disease, diabetes and alcoholism, were excluded. The control group was formed by 12 healthy subjects, which were studied for another purpose. We analyzed nine variables, including ejection fraction, peripheral vascular resistance, systolic and diastolic circumferential stress, left ventricular mass, left ventricular end diastolic and systolic volumes as well as force-velocity and force-fiber length relationship. The patients were followed up from 8 to 60 months (average 39 months). The cases with PDC were divided in two groups, "compensated" and "decompensated". The last ones with low ejection fraction and significantly increases systolic stress. We investigated which was the mechanism of compensation and decompensation through the force-velocity and force-fiber length relation. We found that compensation is associated with great increase of the after-load forces, the more end systolic volume at the end of the systole is not only controlled by the "force", but the decompensation is developed when the hypocontractility is added to the incompetence to compensate the after load. We found that the three deaths in this study had these hemodynamic characteristics, being the cause of death: the presence of heart failure in two patients and ventricular fibrillation in one.(ABSTRACT TRUNCATED AT 250 WORDS)

The long-term prognosis and causes of death of myocardial infarction (MI) in 62 patients with diabetes were studied. The mean follow-up time was 6.2 years. 11 cases died in the acute period of MI (8 weeks following onset of AMI), 9 cases of them (81.8%) had anterior infarction and their major causes of death were ventricular fibrillation and cardiogenic shock (72.2%). 19 cases died in the follow-up period, among them 14 cases (73.68%) had inferior and anterior-septal infarction; most of them died of reinfarction and sudden death. The cumulative survival rate 1.2 and 5 years after MI was 80.7%, 71.9% and 57.9%, respectively. The blood glucose level of the fatal group and the level of CPK and GOT of patients who died in the acute period were higher than those in the surviving group. The results suggest that treatment of myocardial infarction in patients with diabetes be more attentive to prevent ventricular fibrillation and cardiogenic shock during the acute period. After the acute period more attention should be paid to prevent reinfarction and and drop the blood glucose level at normal as possible.

The effects of the first generation sulphonylurea compound gliclazide and the second generation sulphonylurea compound glipizide on strophanthidin toxicity was investigated in rabbits. The sulphonylurea pretreated animals were intravenously infused with 23 mumol/kg strophanthidin until the appearance of the first ventricular ectopic beat and continued thereafter until the appearance of ventricular fibrillation. The first generation sulphonylurea gliclazide increased, while the second generation sulphonylurea glipizide decreased the strophanthidin toxicity in a dose dependent manner. It was concluded that instead of first generation sulphonylureas, second generation sulphonylureas must be preferred in cardiac glycoside treated diabetics, when sulphonylurea treatment is necessary.

A prospective study correlated coronary risk factors with new coronary events in 192 elderly men and 516 elderly women, mean age 82 +/- 8 years. Follow-up was 41 +/- 6 months (range 24-44). Coronary events (myocardial infarction, primary ventricular fibrillation, and sudden cardiac death) occurred in 64 of 192 men (33%) and in 149 of 516 women (29%), P not significant. Using univariate analysis, significant risk factors for coronary events were antecedent coronary artery disease, cigarette smoking, hypertension, diabetes mellitus, serum total cholesterol (TC) greater than or equal to 200 mg/dL and greater than or equal to 250 mg/dL, serum high-density lipoprotein cholesterol (HDL-C) less than 35 mg/dL, and serum TC/HDL-C greater than or equal to 6.5 in men and women, and obesity in women. Using multivariate analysis, significant risk factors for coronary events were age, antecedent coronary artery disease, cigarette smoking, hypertension, diabetes mellitus, and serum TC in men and women and serum HDL-C and serum triglycerides in women. Using univariate analysis, significant risk factors for coronary events in men and women with antecedent coronary artery disease were cigarette smoking, diabetes mellitus, serum TC greater than or equal to 250 mg/dL, and serum TC/HDL-C greater than or equal to 6.5. Using multivariate analysis, significant risk factors for coronary events in men and women with antecedent coronary artery disease were age, cigarette smoking, diabetes mellitus, serum TC, serum HDL-C, and serum triglycerides.(ABSTRACT TRUNCATED AT 250 WORDS)
