We investigated the link between the eight basic emotions named by Plutchik and heart rate, heart-rate variability in the 114 patients, 86 men and 28 women (M = 53.8 yr., SD = 8.0) with acute coronary heart disease during the initial 24-hr. stay in the coronary care unit and again at hospital discharge. Variability in heart rate was significantly positively associated with scores on Trust (the emotional state acceptance) at hospital admission and discharge in the patients with unstable angina and non-Q-wave infarction, on Aggression in the patients with unstable angina at hospital discharge and at hospital admission in the patients with non-Q-wave infarction. There was inverse relation on Timid (the emotional state fear) and Gregarious (joy) at hospital admission and on Distrust (disgust or rejection), Depressed (sadness), and Dyscontrol (impulsiveness) at hospital discharge in the patients with non-Q-wave infarction. There was no significant association between heart-rate variability and the scores on the Emotion Profile Index in the patients with anterior and posterior myocardial infarction. There was no statistically significant association between heart rate and scores on the Emotion Profile Index in the patients with acute coronary disease at hospital admission and discharge. Our results suggest psychological interventions that enhance emotional states represented by the Trust and Aggression scales and minimize those represented by Depressed, Dyscontrol, Timid, and Distrust scales could have a beneficial effect on cardiovascular function in the patients with unstable angina and non-Q-wave infarction in a hospital setting.

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 Dys-control 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.

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.

We examined the prevalence of Type A behavior indicated on Bonners 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. Pa-dents 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 Bortners 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.

This study examined the prevalence of depression based on scores of 200 patients with acute coronary syndrome on the Emotion Profile Index of Plutchik and its relationship with the type of acute coronary syndrome and the severity of ischemic heart disease. Patients with acute coronary syndrome scored higher on depression than the control group. There was no difference in scores on Depression by type of acute coronary syndrome and no significant mean differences on Depression for patients with and without left ventricular failure. Patients with acute myocardial infarction and ventricular fibrillation scored lower on Depression than other patients with acute myocardial infarction and control group. This study supports the view that patients with acute myocardial infarction and ventricular fibrillation and lower scores on Depression have good prognosis during hospitalization and maybe for the long term.

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 Bortners scale at hospital admission and discharge. 48 patients were classified by their scores on Bortners 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 Bortners 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.

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.

BMC Med. 2013 Jun 4;11:143. https://doi.org/10.1186/1741-7015-11-143 Introduction: Coronary collaterals (CC) are anastomotic connections that can provide an alternative blood supply. They are especially important in the case of the vessel occlusion as they are prerequisite of viability. Collaterals have an indispensable role in any type of chronic total occlusion (CTO) intervention.1 Aim of our study was to analyze angiographic characteristics and clinical relations of collaterals in CTO patients.

Aim To compare the overall and disease-specific mortality of Croatian male athletes who won one or more Olympic medals representing Yugoslavia from 1948 to 1988 or Croatia from 1992 to 2016, and the general Croatian male population standardized by age and time period. Methods All 233 Croatian male Olympic medalists were included in the study. Information on life duration and cause of death for the Olympic medalists who died before January 1, 2017, was acquired from their families and acquaintances. We asked the families and acquaintances to present medical documentation for the deceased. Data about the overall and disease-specific mortality of the Croatian male population standardized by age and time period were obtained from the Croatian Bureau of Statistics (CBS). Overall and disease-specific standard mortality ratios (SMR) with 95% confidence intervals (CI) were calculated to compare the mortality rates of athletes and general population. Results Among 233 Olympic medalists, 57 died before the study endpoint. The main causes of death were cardiovascular diseases (33.3%), neoplasms (26.3%), and external causes (17.6%). The overall mortality of the Olympic medalists was significantly lower than that of general population (SMR 0.73, 95% CI 0.56-0.94, P = 0.013). Regarding specific causes of death, athletes’ mortality from cardiovascular diseases was significantly reduced (SMR 0.61, 95% CI 0.38-0.93, P = 0.021). Conclusions Croatian male Olympic medalists benefit from lower overall and cardiovascular mortality rates in comparison to the general Croatian male population.
