Two year follow-up of cardiac mortality and recurrent cardiac events in patients after acute myocardial infarction or unstable angina.

AIM: To assess the relation between predischarge heart rate, heart rate variability, left ventricular ejection fraction, cardiac mortality, and recurrent non-fatal cardiac events in a 2-year follow-up of 95 patients after acute myocardial infarction or unstable angina. METHODS: Heart rate and heart rate variability were assessed in various portions of a complete 24-hour electrocardiographic recording obtained three weeks after hospital admission. Both the beginning and the length of the analyzed portions varied by 20 minutes (a total of 5,100 RR intervals). RESULTS: During a follow-up period of two or more years, there were 14 cardiac deaths in patients with previous myocardial infarction. Eight patients had recurrent cardiac event and were hospitalized. Twenty-nine patients had an effort-provoked angina. There was a significant positive association between the heart rate and cardiac mortality and significant inverse association between heart rate variability, left ventricula r ejection fraction, and cardiac mortality in postinfarction patients. There was no significant difference in heart rate, heart rate variability, and left ventricular ejection fraction between postinfarction patients and patients with unstable angina with or without secondary cardiac events. CONCLUSION: Changes in the heart rate, heart rate variability, and left ventricular ejection fraction were associated with higher cardiac mortality in postinfarction patients. Secondary non-fatal cardiac events were not associated with these variables in patients after either myocardial infarction or unstable angina.

Heart rate and heart-rate variability in patients with acute coronary heart disease classified on Bortner's scale as type A and type B.

We investigated heart rate and heart-rate variability in 82 patients, 60 men and 22 women (M = 54 yr., SD = 9) with acute coronary heart disease and scores on Bortner's scale at hospital admission and discharge. 48 patients were classified by their scores on Bortner's scale as Type A and 34 as Type B. Patients with acute coronary heart disease classified as Type A had a significantly lower mean heart rate than patients with acute coronary heart disease classified as Type B during the day at hospital admission and discharge and during the night at hospital discharge. Mean heart-rate variability was also significantly higher in the patients with acute coronary heart disease classified as Type A than in the patients with acute coronary heart disease classified as Type B during the day at hospital admission and discharge. The differences between two groups on the average heart rate and heart-rate variability were not significant during the night at hospital admission. In our study the patients with acute coronary heart disease classified by scores on Bortner's scale as Type A had higher vagal tone and more favorable sympathovagal balance than patients classified as Type B. This finding may have implications for the treatment of patients with acute coronary heart disease and may suggest some explanation about the protective effect of Type A behavior also.

Responses to Bortner's scale and the eight basic emotions by patients with acute coronary heart disease at hospital admission and discharge.

We examined the prevalence of Type A behavior indicated on Bortner's scale and the Emotion Profiles of Plutchik in 190 patients, 134 men and 56 women (M age = 50 yr., SD = 9) with acute coronary heart disease at hospital admission and discharge. Type A classification was significantly more common for patients with acute coronary heart disease (75.5% versus 65%) than for the control group. Patients with acute coronary heart disease scored lower on Distrust and Dyscontrolled than the control group. Patients with unstable angina had significantly higher mean scores on Bortner's scale than patients with acute myocardial infarction and recurrent myocardial infarction at hospital discharge. Patients with recurrent myocardial infarction scored lower on Distrust and higher on Timid than patients with unstable angina at hospital admission and discharge. This research suggests that Type A behavior and some emotions are associated with acute coronary heart disease. There was a difference in scores on the Emotions Profiles and scores on Type A behavior in relation to type of acute coronary heart disease. The addition of counseling for Type A behavior to standard cardiac counseling was suggested for reduction in scores on Type A behavior.

Bortner type A scores and eight basic emotions for survivors of ventricular fibrillation and left ventricular failure during acute myocardial infarction.

We examined Bortner scores for behavioral patterns and eight basic emotional dimensions named by Plutchik for patients with acute myocardial infarction who survived ventricular fibrillation and left ventricular failure. There were 70 patients, 48 men and 22 women ages 26 to 69 yr. (M = 54, SD = 8), admitted to the coronary care unit within 24 hours of the onset of a long-lasting chest pain. Six patients survived an episode of ventricular fibrillation that occurred within 24 to 48 hours after their admission. 15 patients developed left ventricular failure and were in Killip Classes II and III. Patients with acute myocardial infarction and left ventricular failure had mean Bortner scores significantly lower than others with acute myocardial infarction and were classed as Type B behavior. There was no difference in Bortner scores between patients with ventricular fibrillation and others with acute myocardial infarction. Patients with acute myocardial infarction and left ventricular failure scored significantly higher on Timid than others with acute myocardial infarction. Patients with acute myocardial infarction and ventricular fibrillation scored significantly lower on Depressed and higher on Distrust than other patients with acute myocardial infarction. Our findings suggest that patients with ventricular fibrillation and low scores on Depressed have good hospital prognosis. They are more critical and tend to reject people and ideas more than patients with acute myocardial infarction. This study suggests that the way in which patients with acute myocardial infarction react to their infarction, in terms of eight basic emotions and test patterns, is dependent on the complications of myocardial infarction.

Heart rate and heart rate variability in acute coronary heart disease.

The parameters of cardiac autonomic function, heart period length and heart period length variability were investigated in 70 patients, 50 males and 20 females, mean age 54.8 +/- 9.6 years, admitted to coronary care unit. There were 15 unstable angina patients, 21 anterior wall infarction patients, 20 posterior wall infarction patients, and 14 non-Q-wave infarction patients, who survived to discharge. Heart period length and heart period length variability for each patient were manually measured on the basis of 30 consecutive sinus normal-to-normal RR intervals in ECG every 20 minutes during the initial 24 hours of their stay at the coronary care unit and in the third week after admission. For each interval analyzed, the mean duration of RR interval was computed. RR interval variations were expressed as coefficient of variation (CV). On admission, heart rate was significantly slower (848 +/- 173 ms vs. 837 +/- 163 ms) and CV significantly lower (4.8 +/- 4.2 vs. 5.0 +/- 3.4%) than on discharge (p < 0.01). The significant difference in the mean RR interval between anterior wall infarction patients (802 +/- 186 ms) and inferior wall infarction patients (879 +/- 181 ms) recorded on admission disappeared on discharge from hospital (806 +/- 144 vs. 783 +/- 100 ms). CV was lower in acute myocardial infarction patients (4.7 +/- 3.6; 4.1 +/- 3.2) than in unstable angina patients (5.3 +/- 5.6) on admission (p < 0.05). Heart rate variability was greater in anterior wall infarction patients and unstable angina patients (CV = 5.3 +/- 3.1; 5.2 +/- 3.6%) than in posterior wall infarction patients and non-Q-wave infarction patients (CV = 4.7 +/- 3.5; 4.8 +/- 3.6%). The findings showed that different degrees of cardiac sympathovagal activity may occur in acute coronary heart disease patients during the first 24 hours of their stay at coronary care unit and on discharge from hospital.

Type A/B behavior and eight basic emotions in 1084 employees.

We examined the prevalence of Type A/B behavior and Emotion Profiles in 1084 employees. This report focused on the relationship between Type A behavior and eight basic emotion dimensions. Of the 1084 subjects 710 (65%) scored as Type A and 374 (34.5%) as Type B. The mean Bortner scores for all subjects were 182.8 (SD = 33.7), scores on emotional dimensions for Incorporation and Reproduction were high, and intensities for Ejection and Destruction were low; mean scores on other emotions were normal. Significant differences between Type A and Type B scores were found on six emotional dimensions. Subjects classified as Type A had ratings lower on trustful, controlled, and timid and higher on aggressive, distrustful, and uncontrolled than did persons classified as Type B. There were no differences between Type A and Type B scores on the emotion dimensions of Reproduction and Deprivation. Our data suggest multiple emotional components may comprise the Type A behavior pattern. This is important for behavioral counseling programs and early preventive efforts which could be aimed at reducing the intensity of Type A behaviors.

Relationship of eight basic emotions with age, sex, education, satisfaction of life needs, and religion.

Personality scores of Croatian men and women by age, occupation, education, satisfaction of life needs, and religion were examined. 842 men and 242 women whose mean age was 42 yr. (SD, 8) represented manual labor, clerical work, and management. Employees were administered the Emotions Profile Index and a test of Life Needs Satisfaction. The Croatian women scored lower on Distrustful and Dyscontrol than the Croatian men and higher on Depression and Gregarious. Scores on Aggression, Depression, and Gregarious varied across age groups. The Reproduction scores of sociable and affectionate were significantly higher for managers and persons with university education. The religious employees scored higher on Depression than nonreligious persons. The Reproduction scores were significantly positively associated with all needs satisfaction scores. The Destruction scores (Aggression, Depression) were significantly negatively associated with most life needs satisfactions. The present analysis suggests men and women from Croatian groups have different personality profiles. Correlations of emotional scores with ages, occupations, education, life needs satisfaction, and religion could help in modification toward positive emotional dimensions.

Association of scores for Type A behavior with age, sex, occupation, education, life needs satisfaction, smoking, and religion in 1084 employees.

The associations of Type A or B behavior with age, sex, occupation, education, life needs satisfaction, smoking, and religion were studied. 242 women and 842 men, ages 21 to 64 years, (M age 42 +/- 8 yr.), completed the Bortner scale and rated on a 5-point scale their life needs satisfaction. Information on age, occupation, education, cigarette smoking, and religion were obtained from each subject. Scores for Type A and Type B behavior patterns in different age groups were very similar. Scores on Type A behavior were significantly more common in women than men. Type A behavior scores were identified in a larger proportion of managers, clerks, and in persons with university education than in manual workers and persons with only primary and secondary education. There was no difference between smokers and non-smokers and religious and nonreligious scorers. There was no difference in ratings for life needs satisfaction between persons identified as having scores on Type A and Type B behavior. The present analyses enhance our understanding of Type A behavior as related to age, sex, occupation, education, and life needs satisfaction in a Croatian sample.

Relationship of eight basic emotions, life needs satisfaction and Type A behavior with body mass index and some biochemical characteristics in healthy blue-collar workers.

Studies of the relationship of eight basic emotion dimensions according to Plutchik, life needs satisfaction and Type A behavior with plasma cholesterol, triglyceride and glucose concentrations, and body mass index (BMI) were performed in 137 healthy blue-collar workers. Plasma cholesterol correlated positively with emotion dimensions of destruction and deprivation (r = +0.18, +0.21; p < 0.05) and negatively with the components of love in EPI (reproduction and incorporation; r = -0.24, -0.25; p < 0.01) and life needs satisfaction (family relationships, relationship with friends; r = -0.20, -0.17; p < 0.05). Triglycerides correlated negatively with satisfaction of life needs concerning health, family and friend relationships (r = -0.20, -0.20, 0.25; p < 0.05). Plasma glucose correlated positively with emotions of destruction and orientation (r = +0.22, +0.20; p < 0.05), and negatively with incorporation and reproduction (r = -0.22, -0.24; p < 0.01). BMI correlated positively with plasma cholesterol, triglyceride and glucose concentrations (r = +0.37, +0.40, +0.24; p < 0.01), and emotion of deprivation (r = +0.21; p < 0.01). Results of the study suggested the successful approach to the prevention of coronary heart disease to be related with certain basic emotions, life needs satisfaction and BMI.

Arterial hypertension in workers: prevalence, awareness, treatment, control and heart changes.

Hypertension prevalence, awareness of high blood pressure, its treatment and control were estimated in 1100 workers, between the ages 35 and 59. Hypertension was defined as blood pressure > or = 160/95 mm Hg. The incidence of hypertensive heart disease was also investigated. All hypertensive persons were taken M-mode and 2-dimensional echocardiograms, electrocardiogram and chest X-ray. The criteria for both sexes were Casale's ECG for left ventricular hypertrophy and echocardiographic left ventricular mass index of 120 g/m or greater. The prevalence of hypertension was 14%. The percentage of persons who were aware of hypertension but did not receive treatment was 66%; 28% were treated but were not adequately controlled for high blood pressure. Only 6% of hypertensive workers received treatment and had high blood pressure under control. The prevalence of heart changes among the hypertensive workers as determined by echocardiographic standards was 67%, by electrocardiographic standards 19% and chest X-ray standards 29%. Systolic blood pressure was significantly related to ventricular mass (r = 0.34; 0.26) and voltage of R in a VL + S in V3 (r = 0.28; 0.24) in all hypertensive subjects, irrespective of treatment. Our study showed a high prevalence of hypertensive heart disease, 100% awareness of disorder and a low rate of treatment and control.

Penetrating heart wounds repaired without cardiopulmonary bypass. Evaluation and follow-up of recent war injuries.

Penetrating cardiac injuries requires urgent management. Between September 1991 and June 1992, 10 patients with penetrating cardiac injuries sustained in war were treated at our hospital in Croatia, which does not have cardiopulmonary bypass facilities. Seven of these patients survived cardiorrhaphy and were discharged from the hospital, subject to follow-up. In 5 of the survivors, the injuries were inflicted by fragments from explosive devices; in 1 survivor, by a bullet; and in 1 survivor, by a rib fragment. The left ventricle was lacerated in 4 patients, the right ventricle in 2, the left atrium in 1, and the right atrium in 2. One patient had sustained laceration of the left anterior descending coronary artery in addition to a left ventricular laceration. During early post-cardiorrhaphy evaluation, all patients showed ST segment changes on electrocardiography. The most common echocardiographic findings were pericardial effusion in 5 patients (71%) and intramyocardial foreign bodies in 3 patients (43%). After 5 to 10 months of follow-up, the most common echocardiographic findings were enlargement of the injured chamber in 6 patients (86%), intramyocardial foreign bodies in 3 patients (43%), and hypokinesis of the injured wall in 2 patients (29%). Resting electrocardiographic results and exercise testing results were normal in all patients. One patient had arrhythmias during 24-hour Holter monitoring. Patients surviving operation had a rapid recovery, and were asymptomatic when last seen at follow-up. This demonstrates that treatment of penetrating injuries of the heart can be very successful, at least in the short term, even in hospitals without cardiopulmonary bypass facilities.

[Relation of somatic and psychosocial factors to systemic pressure in hypertensive and normotensive workers].

A cohort of 900 workers aged 35-59 years underwent clinical, electrographical and psychological examinations. The prevalence of arterial hypertension was 15.2%. Family history of hypertension was positive in 87 (63.5%) hypertensive and 41 (29.9%) normotensive workers (P less than 0.01). The mean body index and the mean resting heart rate were significantly higher in the hypertensive than in the normotensive group (P less than 0.01). In the former group 96 (70.1%) persons and in the latter 89 (65%) persons belonged to type A behavior (P greater than 0.05). No significant difference in the intensity of eight basic emotions was found between the hypertensive and normotensive persons (P greater than 0.05). According to multiple regression analysis the most predictive variables of systolic blood pressure in both groups were age and resting heart rate. The two variables were more significant predictors in the hypertensive than in the normotensive group. The most predictive variable of diastolic blood pressure among the normotensive workers was body index. For the hypertensive workers this variable was not a significant predictor of diastolic blood pressure. The eight basic emotions according to Plutchik and the life need satisfaction were not significant predictors of systemic blood pressure either with the hypertensive or normotensive workers.
