Abstract
BACKGROUND We investigated whether depressive disorder and Type D personality refer to different forms of distress in the Myocardial INfarction and Depression - Intervention Trial (MIND-IT). METHOD A total of 1205 myocardial infarction (MI) patients were screened at 3, 6, 9 and 12 months post-MI; those with a Beck Depression Inventory (BDI) score 10 underwent the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI). Patients completed the DS14 measure of Type D personality at 12 months and were stratified to one of four subgroups: depressed/Type D, depressed/non-Type D, non-depressed/Type D, or non-distressed. RESULTS Two hundred and six (17%) patients were diagnosed with depression and 224 (19%) with Type D. Only 7% (n=90) had both forms of distress, and 60% of Type D patients were free of depression in the first year post-MI. Type D moderated the relationship between depressive and cardiac disorder. Depressed patients without Type D had the worst clinical status (left ventricular dysfunction, heart failure, Killip class 2) as compared to other patients, whereas depressed patients with a Type D personality did not differ in clinical status from non-distressed patients. Contrasting 'pure' Type D and depression subgroups showed that Type D patients without depression were less likely to have left ventricular dysfunction [odds ratio (OR) 0.47, 95% confidence interval (CI) 0.35-0.65, p<0.0001] than depressed patients without Type D. CONCLUSIONS Depression and Type D refer to different forms of distress in post-MI patients; most Type D patients display non-psychiatric levels of distress and Type D moderates the relationship between depressive and cardiac disorder. Different depression/Type D subgroups may be involved in the prediction of cardiac prognosis.

Abstract
OBJECTIVE Emotional distress has been related to clinical events in patients with coronary artery disease, but the influence of positive affect (i.e. mood states such as activity, joy and cheerfulness) has received little attention. Therefore, we wanted to investigate the role of positive affect on clinical outcome after percutaneous coronary intervention (PCI) with stent implantation in these patients. DESIGN Prospective follow-up study. At baseline, patients from the Rapamycin-Eluting Stent Evaluated At Rotterdam Cardiology Hospital (RESEARCH) registry completed measures of positive affect, depression and anxiety post-PCI. Patients with reduced positive affect scored 1 SD below the mean score. SETTING University Hospital; Thoraxcenter of the Department of Cardiology. SUBJECTS 874 patients (72% men; 62.2 +/- 10.9 years) from the RESEARCH registry. Main outcome measure. Death or myocardial infarction (MI) 2 years post-PCI. RESULTS At follow-up, there were 52 clinical events (deaths n = 27, MIs n = 25). Reduced positive affect and depression/anxiety were associated with poor prognosis, but reduced positive affect was the only independent predictor of events. The incidence of death/MI in adequate versus reduced positive affect patients was 4% (29/663) vs. 11% (23/211); HR = 2.55 (95% CI 1.46-4.34, P = 0.001), adjusting for clinical variables. Reduced positive affect and diabetes were independent prognostic factors, and patients with one (HR = 2.84, 95% CI 1.58-5.10) or both (HR = 5.61, 95% CI 2.25-13.99) of these factors had a higher risk when compared with nondiabetic patients with adequate positive affect, P < or = 0.003. CONCLUSIONS Reduced positive affect independently predicted death/MI following stent implantation, and improved risk stratification above and beyond diabetes.

Abstract
BACKGROUND Although many studies have focused on post-myocardial infarction (MI) depression, there is limited information about the evolution and determinants of depressive symptoms in the first year post-MI. Therefore we examined (1) the course of depressive symptoms during the first year post-MI and (2) the predictors of these symptom trajectories. METHOD To assess depressive symptoms, 287 patients completed the Beck Depression Inventory during hospitalization for MI, and 2, and 12 months post-MI. Personality was assessed with the Type-D scale during hospitalization. We used latent class analysis to examine the evolution of depressive symptoms over a 1-year period and multinomial logit regression analyses to examine predictors of these symptom trajectories. RESULTS The course of depressive symptoms was stable during the first year post-MI. Four groups were identified and classified as non-depressed [40%, intercept (IC) 2.52], mildly depressed (42%, IC 6.91), moderately depressed (14%, IC 13.73) or severely depressed (4%, IC 24.54). In multivariate analysis, cardiac history (log OR(severe) 2.93, p=0.02; log OR(moderate) 1.81, p=0.02; log OR(mild) 1.46, p=0.01), history of depression (log OR(severe) 4.40, p<0.001; log OR(moderate) 1.97, p=0.03) and Type-D personality (log OR(severe) 4.22, p<0.001; log OR(moderate) = 4.17, p<0.001; log OR(mild) 1.66, p=0.02) were the most prominent risk factors for persistence of depressive symptoms during the first year post-MI. CONCLUSIONS Symptoms of depression tend to persist during the first year post-MI. Cardiac history, prior depression and Type-D personality were identified as independent risk factors for persistence of depressive symptoms. The results of this study strongly argue for routine psychological screening during hospitalization for acute MI in order to identify patients who are at risk for chronicity of depressive symptoms and its deleterious effects on prognosis.

Abstract
OBJECTIVE It has been argued that health status and quality of life (QOL) should be taken into account in the treatment policy of patients with peripheral arterial disease (PAD). In cardiac patients, it has been shown that poor perceived health status is an independent predictor of mortality and hospitalization. We therefore examined (1) the role of health status, QOL, and clinical indices of disease severity as determinants of invasive treatment in patients with PAD and (2) the effect of invasive treatment on health status and QOL. METHODS At their first visit, patients completed the RAND 36-item Health Survey and World Health Organization Quality of Life assessment instrument questionnaires to assess health status and QOL, respectively. During the 1-year follow-up period, data concerning hospitalization were derived from the patients' medical files. Furthermore, patients completed the RAND 36 and the World Health Organization Quality of Life assessment instrument again at 1-year follow-up. The setting was a vascular outpatient clinic of a teaching hospital in Tilburg, The Netherlands; participants were 200 consecutive patients newly diagnosed with intermittent claudication, a common expression of PAD. Diagnosis was based on history, physical examination, treadmill walking distance, and ankle-brachial pressure indices. Main outcome measures were (1) invasive treatment of PAD that took place during the 1-year follow-up, derived from the patients' medical files, and (2) health status and QOL after 1 year of follow-up. RESULTS After 1 year of follow-up, 107 patients (53.5%) were event free, whereas 77 patients (38.5%) had been hospitalized for invasive treatment of PAD. Sixteen patients (8%) were hospitalized for other cardiovascular reasons. In a multivariate logistic regression model, age (odds ratio [OR], 0.95; 95% confidence interval [CI], 0.91-0.99; P = .024), pain-free walking distance (OR, 2.74; 95% CI, 1.05-7.17; P = .04), and physical functioning (OR, 4.46; 95% CI, 1.79-11.12; P = .001) were independent predictors of invasive treatment of intermittent claudication. After 1 year of follow-up, patients who were treated invasively experienced a significant improvement in their physical functioning ( P = .004), role limitations due to emotional problems ( P = .018), and bodily pain ( P = .026). CONCLUSIONS Patients with poor self-reported physical functioning, limited walking distance, and a younger age were likely to be treated invasively. The physician's clinical judgment about when to intervene adequately reflects the patient's own opinion about his or her health status. Invasive treatment led to a significant improvement in patients' health status. These findings indicate the effectiveness of the strategy to include patients' perceived physical functioning into the process of clinical decision-making.

Abstract
OBJECTIVES In this study patients with documented ischemic coronary heart disease (ICHD; prior MI or CAD per catheterization) were tested for the association of various measures of emotional distress with Age at Initial Diagnosis. METHODS The measures were chosen because of a published track record at predicting mortality in this population. Females were oversampled to achieve equivalent numbers of each sex (n=50), and thus equivalent statistical power. In a subset of patients (38 males and 32 females), Spouse/Friend Ketterer Stress Symptom Frequency Checklists (KSSFCs) were received. RESULTS Females reported more depression and anxiety than males. However, spouses or friends reported more anger for males. Denial (spouse/friend minus self-ratings) was greater in males for all three scales of the KSSFC (Anger, P=.005; Depression, P=.024; Anxiety, P=.001). Although females showed the same trend, self and spouse or friend ratings of distress were significantly associated with Age at Initial Diagnosis only in males. When split at the sample mean on the Spouse/Friend KSSFC AIAI (Anger) scale, Age at Initial Diagnosis occurred 14.2 years earlier in males. CONCLUSIONS Use of a significant other in assessing psychosocial/emotional distress in males may confer greater accuracy, and therefore predictive power for clinical endpoints.

Abstract
With an ageing population and a decline in cardiac mortality rates, the number of patients with cardiac disease is increasing, which in turn poses a major challenge for secondary prevention. For this end, appropriate, sensitive, and validated instruments to assess health complaints and quality of life are required. The objectives of the current study were: (1) to cross-validate the Health Complaints Scale (HCS) in a Danish sample of patients with a first myocardial infarction (MI); and (2) to investigate whether perceived health, as measured by the HCS is related to cardiac disease severity. The HCS was originally developed in Belgian patients with coronary artery disease. One-hundred-and-twelve consecutive patients with a first myocardial infarction were assessed by means of a questionnaire four to six weeks post infarction. Clinical measures were sampled from medical records. The factor structure of the HCS and the internal consistency of the Somatic Complaints (alpha = 0.91) and Cognitive Complaints subscales (alpha = 0.94) were confirmed. The construct validity of the scale was confirmed against measures of psychopathology and personality. Patients scored significantly higher on the HCS Somatic and Cognitive scales as compared with self-reports of depression and anxiety (p < 0.0001). Health complaints were unrelated to severity of cardiac disease and rather reflected subjective perception of quality of life. These findings show that the HCS is a valid instrument that is equally applicable in Danish cardiac patients to monitor perceived health as a major component of quality of life.

Abstract
BACKGROUND The impact of treating emotional distress on prognosis in coronary heart disease (CHD) has not been documented convincingly. We tested the hypothesis that treatment-related changes in emotional distress may explain the beneficial effect of rehabilitation on prognosis. METHODS AND RESULTS In this nonrandomized clinical trial, 150 men with CHD participated in rehabilitation (n=78) or received standard medical care (n=72). There were no differences between rehabilitation and control patients with regard to left ventricular ejection fraction (LVEF) or standard care. End points were reduction in distress after 3 months and mortality after 9 years. At the end of the 3-month trial, 64 patients (43%) reported improvement and 22 (15%) reported deterioration in negative affect. Rehabilitation patients improved more (P=0.004) and deteriorated less (P=0.001) than control patients; rehabilitation was effective in reducing distress. After 9 years of follow-up, 15 patients had died (13 cardiac and 2 cancer deaths). Mortality was associated with LVEF </=50% (P=0.038) and deterioration in negative affect (P=0.007). Rate of death was 17% (12/72) for control patients versus 4% (3/78) for rehabilitation patients (P=0.009); rehabilitation was effective in reducing mortality. LVEF </=50% (OR 3.2; 95% CI 1.1 to 9.8; P=0.041) and rehabilitation (OR 0.2; 95% CI 0.1 to 0.7; P=0.016) were independent predictors of mortality. Rehabilitation warded off the deleterious effect of deterioration in negative affect on prognosis. CONCLUSIONS Deterioration in negative affect is associated with a high long-term mortality risk. Warding off deterioration in negative affect is a mechanism that may explain the beneficial effect of comprehensive rehabilitation on prognosis in patients with CHD.

Abstract
This study evaluated screening abilities of self-report questionnaires for depression in first myocardial infarction (MI) patients. One month post-MI, 206 patients with first MI were screened for major and minor depression using the 90-item Symptom Check List (SCL-90), the Beck Depression Inventory (BDI), the Hospital Anxiety and Depression Scale (HADS), and the 17-item Hamilton Depression Rating Scale (Ham-D). The Structured Clinical Interview for DSM-IV criteria was used as the gold standard. Sensitivity and specificity for different cutoff points, using relative operating characteristics curves, were assessed. The internal consistency for all scales was good. When screening for major and minor depression, the optimal cutoff scores are lower than those for screening major depression only. The SCL-90, BDI, HADS, and Ham-D proved to have acceptable abilities for screening post-MI major and minor depression.

Abstract
BACKGROUND Prognosis of solid organ cancer in immunosuppressed hosts is generally dismal. Therefore, every effort to identify patients with asymptomatic carcinomas before transplantation should be encouraged. METHODS Sixty-seven patients referred for heart transplantation were examined adhering to the scheme proposed at the 24th Bethesda Conference. To increase the sensitivity of this work-up, the following items were added: tumor marker assays (prostate-specific antigen in males, carcino embryogenic antigen), abdominal ultrasound, CT scan of the abdomen and the thorax, mammography/echography of the breasts, PAP smear, colonoscopy if carcino embryogenic antigen abnormal or occult blood in stool, prostate echography if prostate-specific antigen abnormal or prostate hypertrophy. RESULTS Carcinoma was detected in 10 of the 67 patients; for 8 patients of this cancer group, transplantation was denied. Importantly, 9 of the 10 malignancies were detected by means of the diagnostic items that were added to the standard screening protocol. There were no significant differences between the cancer and the non-cancer group regarding mean age, sex, etiology of heart failure, and smoking history. Stratifying patients in younger (i.e., < or =54 years) and older (i.e., > or =55 years) age groups showed a significantly greater proportion of older patients in the cancer group (8/10=80%) compared to the non-cancer group (25/57=44%), P=0.04. After a mean follow-up of 34 months, 5 of the 36 transplanted patients developed a malignancy (4 skin carcinomas, 1 non-Hodgkin lymphoma). There have been no malignancy-related deaths until now. CONCLUSION The importance of a thorough screening program in the triage of candidates with preexisting malignancies, especially in an older patient population, is illustrated in this report.

Abstract
OBJECTIVE Acute and chronic psychological distress have been associated with coronary heart disease (CHD) but little is known about the determinants of distress as a coronary risk factor. Broad and stable personality traits may have much explanatory power; this article selectively focuses on negative affectivity (NA; tendency to experience negative emotions) and social inhibition (SI; tendency to inhibit self-expression in social interaction) in the context of CHD. METHODS The first part of this article reviews research on NA and SI in patients with CHD. The second part presents new findings on NA and SI in 734 patients with hypertension. RESULTS Accumulating evidence suggests that the combination of high NA and high SI designates a personality subtype ("distressed" type or type D) of coronary patients who are at risk for clustering of psychosocial risk factors and incidence of long-term cardiac events. Type D and its contributing low-order traits (dysphoria/tension and reticence/withdrawal) could also be reliably assessed in a community-based sample of patients with hypertension. This finding was replicated in men and women, and in Dutch- and French-speaking subjects. Type D hypertensives reported more depressive affect than their non type D counterparts. CONCLUSIONS There is an urgent need to adopt a personality approach in the identification of patients at risk for cardiac events. NA and SI are broad and stable personality traits that may be of special interest not only in CHD, but in other chronic medical conditions as well.

Abstract
BACKGROUND Improvement in treatment of patients with coronary heart disease (CHD) has caused longer survival but also an increase in the number of patients at risk for subsequent cardiac events and impaired quality of life (QOL). We hypothesized that chronic emotional distress confers an increased risk of poor outcome despite appropriate treatment. METHODS AND RESULTS This prospective study examined the 5-year prognosis of 319 patients with CHD. Baseline assessment included symptoms of depression/anxiety and distressed personality type (type D-ie, high negative affectivity and social inhibition). The main end points were cardiac death or nonfatal myocardial infarction and impaired QOL. There were 22 cardiac events (16 nonfatal); they were related to left ventricular ejection fraction (LVEF) </=50%, poor exercise tolerance, age </=55 years, symptoms of depression, and type D personality. Multivariate analysis yielded LVEF </=50% (OR, 3.9; P=0.009), type D personality (OR, 8.9; P=0.0001), and age </=55 years (OR, 2.6; P=0.05) as independent predictors of cardiac events. Convergence of these risk factors predicted the absence of the expected therapeutic response that was observed in 10% of the patients. When 2 or 3 risk factors occurred together, the rate of poor outcome was 4-fold higher (P=0. 0001). Estimates of medical costs increased progressively with an increasing number of risk factors. Smoking, symptoms of depression, and type D personality were independent predictors of impaired QOL. CONCLUSIONS Decreased LVEF, type D personality, and younger age increase the risk of cardiac events; convergence of these factors predicts nonresponse to treatment. Emotionally stressed and younger patients with CHD represent high-risk groups deserving of special study.

Abstract
Clinical diagnoses of depression, self-reported negative emotions, and personality traits have been associated with both the development and progression of coronary heart disease (CHD). This article focusses on negative affectivity (the tendency to experience negative emotions) and social inhibition (the tendency to inhibit self-expression in social interaction) in CHD patients. Two independent samples of patients with CHD were included in this study. Both empirical and internal-structural criteria were used to devise a brief self-report measure comprising an eight-item negative affectivity and an eight-item social inhibition scale in Sample 1 (N = 400). These scales were internally consistent (alpha = .89 and .82), stable over time (three-month test-retest reliability = .78 and .87) and were validated against standard personality scales. CHD patients with a "distressed" personality (Type-D) report high levels of negative affectivity and social inhibition; accordingly, this self-report measure was termed Type-D Scale-16 (DS16). Previous research showed that Type-D was associated with cardiac events and incidence of cancer in patients with CHD. Type-D as measured by the DS16 was associated with depressive affect and symptoms, stress, poor self-esteem, dissatisfaction with life, and low positive affect in Sample 2 (N = 100) of the present article. It is concluded that research on CHD should focus on affective disorder, specific negative emotions, and global personality traits, and that the DS16 is a practical, sound research tool that can be used to assess Type-D.

Abstract
BACKGROUND There still is much debate with regard to the role of psychosocial factors in cancer. Evidence suggests that cancer and coronary heart disease (CHD) may have common causes. This study examined the role of pessimism, anxiety and personality in the development of cancer among men who had been diagnosed with CHD but were free of cancer at baseline. METHODS Two hundred and forty-six men who were treated for CHD, but were free of cancer, filled out psychological scales at baseline. Patients and their families were contacted after 6-10 years to determine the incidence of cancer. RESULTS At follow-up, 12 patients (5%) had been diagnosed with cancer (9 cancer deaths). Development of cancer was unrelated to cardiac pathology but was associated with age > or = 56 years, poor exercise tolerance, pessimism and anxiety. The rate of cancer was 8/60 = 13% for men with a distressed personality (type-D) and 4/186 = 2% for non-type-D men (P = 0.002); rate of cancer death was 10% and 2%, respectively (P = 0.007). Type-D refers to the interaction between high negative affectivity and high social inhibition. Regression analysis yielded older age (odds ratio 4.6, 95% CI 1.5-14.3) and type-D (odds ratio 7.2, 95% CI 2.9-18.1) as independent prognostic factors for cancer. CONCLUSIONS Type-D personality was a prognostic factor for the development of cancer in men with established CHD. Psychosomatic research should take a broad enough view of the specific and the global psychosocial variables that may play a role in both cancer and CHD.

Abstract
BACKGROUND Patients with myocardial infarction (MI) with a decreased left ventricular ejection fraction (LVEF) have a poor prognosis, but the role of emotional stress in prognosis is not known. We hypothesized that emotional stress in these patients (1) is unrelated to the severity of cardiac disorder, (2) predicts cardiac events, and (3) is a function of basic personality traits. METHODS AND RESULTS Eighty-seven patients with MI (age, 41 to 69 years) with an LVEF of < or =50% underwent psychological assessment at baseline. Patients and their families were contacted after 6 to 10 years (mean, 7.9 years); cardiac events were defined as cardiac death or nonfatal MI. Emotional distress was unrelated to the severity of cardiac disorder. At follow-up, 21 patients had experienced a cardiac event (13 fatal events). These events were related to LVEF of < or =30%, poor exercise tolerance, previous MI, anxiety, anger, and depression (all P< or =.02). Patients with a distressed personality (type D; ie, the tendency to suppress negative emotions) were more likely to experience an event over time compared with non-type D patients (P=.00005). Cox proportional hazards analysis yielded LVEF of < or =30% (relative risk, 3.0; 95% confidence interval, 1.2 to 7.7; P=.02) and type D (relative risk, 4.7; 95% confidence interval, 1.9 to 11.8; P=.001) as independent predictors. Anxiety, anger, and depression did not add to the predictive power of type D; these negative emotions were highly correlated and reflected the personality domain of negative affectivity. CONCLUSIONS Personality influences the clinical course of patients with a decreased LVEF. Emotional distress in these patients is unrelated to disease severity but reflects individual differences in personality. Clinical trials should take a broad view of the target of intervention; assessment of LVEF and personality may identify patients at risk.

Abstract
BACKGROUND Emotional distress has been related to mortality in patients with coronary heart disease (CHD), but little is known about the role of personality in long-term prognosis. We postulated that type-D personality (the tendency to suppress emotional distress) was a predictor of long-term mortality in CHD, independently of established biomedical risk factors. METHODS We studied 268 men and 35 women with angiographically documented CHD, aged 31-79 years, who were taking part in an outpatient rehabilitation programme. All patients completed personality questionnaire at entry to the programme. We contacted them 6-10 years later (mean 7-9) to find out survival status. The main endpoint was death from all causes. FINDINGS At follow-up, 38 patients had died; there were 24 cardiac deaths. The rate of death was higher for type-D patients than for those without type-D (23 [27%]/85 vs 15 [7%]/218; p < 0.00001). The association between type-D personality and mortality was still evident more than 5 years after the coronary event and was found in both men and women. Mortality was also associated with impaired left ventricular function, three-vessel disease, low exercise tolerance, and the lack of thrombolytic therapy after myocardial infarction. When we controlled for these biomedical predictors in multiple logistic regression analysis, the impact of type-D remained significant (odds ratio 4.1 [95% CI 1.9-8.8]; p = 0.0004). In this group of CHD patients, type-D was an independent predictor of both cardiac and non-cardiac mortality. Social alienation and depression were also related to mortality, but did not add to the predictive power of type-D. INTERPRETATION We found that type-D personality was a significant predictor of long-term mortality in patients with established CHD, independently of biomedical risk factors. Personality traits should be taken into account in the association between emotional distress and mortality in CHD.

Abstract
Previous research showed: a) emotional distress is a risk factor for mortality after myocardial infarction (MI) and b) emotional distress is linked to stable personality traits. In this study, we examined the role of these personality traits in mortality after MI. Subjects were 105 men, 45 to 60 years of age, who survived a recent MI. Baseline assessment included biomedical and psychosocial risk factors, as well as each patient's personality type. After 2 to 5 (mean, 3.8) years of follow-up, 15 patients (14%) had died. Rate of death for patients with a distressed personality type (11/28 = 39%) was significantly greater than that for patients with other personality types (4/77 = 5%) (p < .0001). Patients with this personality type tend simultaneously to experience distress and inhibit expression of emotions. Low exercise tolerance, previous MI (p < .005), anterior MI, smoking, and age (p < .05) were also associated with mortality. A logistic regression model including these biomedical factors had a sensitivity for mortality of only 27%. The addition of distressed personality type in this model more than doubled its sensitivity. Of note, among patients with poor physical health, those with a distressed personality type had a five-fold mortality risk (p < .005). Consistent with the findings of other investigators, depression (p < .005), life stress, use of benzodiazepines (p < .01), and somatization (p < .05) were also related to post-MI mortality. These psychosocial risk factors were more prevalent in the distressed personality type than in the other personality types (p < .001-.05). Multiple logistic regression indicated that these psychosocial factors did not add to the predictive value of the distressed personality type. Hence, an important personality effect was observed despite the low power. This suggests that personality traits may play a role in the detrimental effect of emotional distress in MI patients.

Abstract
Since emotional distress is linked to poor prognosis in coronary patients, there is urgent need for research into interventions that may enhance emotional well-being in these patients. Cardiac rehabilitation aims to return the individual to optimal emotional function, but the psychological effect of this therapy still needs to be demonstrated. Hence, we examined the role of cardiac rehabilitation in enhancing emotional health. We examined 170 male patients with coronary heart disease, of whom 85 had participated in the outpatient rehabilitation programme of the University Hospital of Antwerp and 85 had received standard medical care only in two other hospitals. Rehabilitation and control patients were matched by medical category and tendency to experience distress. The Global Mood Scale, the Health Complaints Scale, and the Heart Patients Psychological Questionnaire were used to assess changes in emotional well-being over a 3-month period. These changes were significantly different as a function of cardiac rehabilitation (P<0.0001). Rehabilitation patients, but not control patients, reported a significant improvement in negative affect, positive affect, well-being , health and disability (P<0.001). At follow-up, differences in depression, tranquillizer use (P<0.05), and activity profile (P<0.01) confirmed that rehabilitation patients displayed more healthy behaviour than control patients. Patients not only improved more, but also deteriorated less as a function of rehabilitation. This therapy also had a positive effect on patients suffering minimal distress, which is at variance with previous research. These findings suggest that comprehensive rehabilitation may be an effective therapy for enhancing emotional well-being in patients with coronary heart disease.

Abstract
Research on coronary heart disease (CHD) lacks sensitive outcome measures. Health complaints, although subjective in nature, may provide information on the degree of recovery from CHD. The purpose of Study 1 was to identify common health complaints in a group of 535 men (mean age, 57.5 years) with CHD. In the weeks after a coronary event, they frequently reported somatic (e.g., chest pain, dyspnea, fatigue, sleep problems) and cognitive (e.g., concern about health and functional status) health complaints. Statistical analyses produced the Health Complaints Scale (HCS), which comprises 12 somatic and 12 cognitive complaints. Confirmatory factor analysis provided evidence for the model undergirding the HCS, and the somatic and cognitive scales of the HCS were found to have high internal consistency (alpha > or = .89), adequate test-retest reliability (r > or = .69), and good construct validity. Study 2 provided evidence for the idea that the HCS can be distinguished from standard scales of psychopathology. Statistical analyses in 266 men with CHD indicated that, compared to symptoms of psychopathology, the HCS scales displayed discrete factor loadings as well as higher scores at baseline and a normal clustering of scores. Important to note, HCS scores decreased in 60 subjects participating in cardiac rehabilitation (p < .0001) but not in 60 control subjects. Although research should not disregard psychological biases on symptom reporting, it is argued that health complaints need to be accurately assessed in CHD patients.

Abstract
I hypothesized that measures that match the theoretically prescribed effect of cardiac rehabilitation (i.e., enhancement of subjective health and well-being) are more appropriate to assess change than are measures of psychopathology. Study 1 examined the differential sensitivity to change of 3 measures in a sample of 162 men with coronary heart disease (CHD) who participated in cardiac rehabilitation. Ss reported less change on the State-Trait Anxiety Inventory and the Symptom Check List than on the Heart Patients Psychological Questionnaire, but in the absence of a control group it is difficult to known what caused this change. In Study 2, 60 men with CHD who participated in rehabilitation were compared with 60 men with CHD who received standard medical care alone. Rehabilitation Ss, but not control Ss, reported a decrease in disability and an increase in well-being as measured by the HPPQ. I concluded that sensitive measures may actually provide evidence for the psychological effect of cardiac rehabilitation.

Abstract
This study examined the thesis that patients with coronary heart disease (CHD) comprise discrete personality subtypes and that identification of these subtypes may benefit biobehavioral research on CHD. Measures of Negative Affectivity, Social Inhibition, and Self-Deception were used to generate a personality taxonomy through cluster analysis in a sample of 405 men with CHD. This empirical taxonomy served as a basis for the development of a conceptual model which delineates hardy, distressed, inhibited, and repressive subtypes. Coronary proneness may differ across these subtypes to the extent that potential behavioral correlates of CHD were associated with subtype membership. Distressed individuals (characterized by elevated levels of Type A behavior, anger, hostility, and life stress) and inhibited individuals (characterized by the nonexpression of anger) may be particularly coronary prone. It is concluded that research should focus on the interaction of global traits that may define subtypes of patients with CHD.
