Abstract
OBJECTIVE Cardiac ischemia during daily life is associated with an increased risk of adverse outcomes. Mental stress is known to provoke cardiac ischemia and is related to psychological variables. In this multicenter cohort study, we assessed whether psychological characteristics were associated with ischemia in daily life. METHODS This study examined patients with clinically stable coronary artery disease (CAD) with documented cardiac ischemia during treadmill exercise (n = 196, mean [standard deviation] age = 62.64 [8.31] years; 13% women). Daily life ischemia (DLI) was assessed by 48-hour ambulatory electrocardiophic monitoring. Psychological characteristics were assessed using validated instruments to identify characteristics associated with ischemia occurring in daily life stress. RESULTS High scores on anger and hostility were common in this sample of patients with CAD, and DLI was documented in 83 (42%) patients. However, the presence of DLI was associated with lower anger scores (odds ratio [OR] = 2.03; 95% confidence interval [CI] = 1.12-3.69), reduced anger expressiveness (OR = 2.04; 95% CI = 1.10-3.75), and increased ratio of anger control to total anger (OR = 2.33; 95% CI = 1.27-4.17). Increased risk of DLI was also associated with lower hostile attribution (OR = 2.22; 95% CI = 1.21-4.09), hostile affect (OR = 1.92; 95% CI = 1.03-3.58), and aggressive responding (OR = 2.26; 95% CI = 1.25-4.08). We observed weak inverse correlations between DLI episode frequency and anger expressiveness, total anger, and hostility scores. DLI was not associated with depression or anxiety measures. The combination of the constructs low anger expressiveness and low hostile attribution was independently associated with DLI (OR = = 2.59; 95% CI = 1.42-4.72). CONCLUSIONS In clinically stable patients with CAD, the tendency to suppress angry and hostile feelings, particularly openly aggressive behavior, was associated with DLI. These findings warrant a study in larger cohorts, and intervention studies are needed to ascertain whether management strategies that modify these psychological characteristics improve outcomes.

Abstract
Participants consisted of 184 patients (160 males, 24 females) with positive angiograms or prior myocardial infarctions who displayed at least 1 mm of ST segment depression on a standardized treadmill test. Mean scores on the Reward Dependence subscale of the Tridimensional Personality Questionnaire were higher in patients displaying ischemia during mental stress. Patients who reported higher levels of irritability/anger in response to the Speech stressor were also more likely to display ischemia. However, this result was primarily a result of the females in the sample whose ratings of interest and irritability were associated with ischemia during the Speech task. Psychometric measures previously found in prospective studies to predict acute cardiac events were unrelated to mental stress-induced ischemia in the laboratory.

Weight change after myocardial infarction--the Enhancing Recovery in Coronary Heart Disease patients (ENRICHD) experience. Am Heart J 2008; 155:478-84. [PMID: 18294480 DOI: 10.1016/j.ahj.2007.10.026] [Citation(s) in RCA: 41] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2007] [Accepted: 10/23/2007] [Indexed: 11/18/2022]
Abstract
BACKGROUND The relationship of changes in weight to outcomes in patients after myocardial infarction (MI) is controversial. METHODS From the ENRICHD trial data, we assessed weight change, and the associations of baseline weight and change at follow-up with outcomes and interactions between psychosocial factors. RESULTS At baseline, 73.6% of patients (n = 1706) were overweight or obese; 134 patients had body mass index of > or = 40. Underweight patients were more likely to die or have nonfatal recurrent MI. After controlling for covariates, overweight and obese patients had similar outcomes to normal-weight patients. Eighteen percent of patients gained > 5%, 27% lost > 5%, and 55% had < or = 5% change in weight. Compared with weight loss of < or = 5%, the risk of death (adjusted hazard ratio 1.74, P = .01) and cardiovascular death (hazard ratio 1.79, P = .04) increased with weight loss of > 5%. After propensity matching, weight loss of > 5% remained as a significant risk factor for death and cardiovascular death. There was no interaction between weight change and depression and/or social support at baseline or follow-up. Weight change was not associated with recurrent MI or cardiovascular hospitalizations. CONCLUSIONS A large proportion of patients lose or gain > 5% of body weight after an MI. The association between obesity and lower mortality is modulated by comorbidities. Weight loss after MI is associated with worse outcomes and is not related to depression or social support.

Abstract
During this meeting, the participants developed a strategic set of recommendations for ASPH to continue to advance the study of tobacco control in public health through research and education/training programs. The meeting focused on sustaining and further developing tobacco-related research and education/ training programs. All four issues were addressed in depth through valuable discussion and exchange and reflected in the nine areas of focus. Recommendations for advocacy for future funding for SPH in tobacco control included developing collaborative relationships with ASPH partners, organizations, and institutions with complementary objectives (state departments of health, third party payors, etc). Priorities for sustaining and further developing research and education/training programs within SPH included developing a focus on particular research areas (e.g., special populations, economic issues, dissemination and translational issues), building on existing knowledge, and attempting to avoid the effects of "siloing" with collaborative relationships and methods for addressing the sustenance of programs beyond initial funding periods. Methods to maintain vigilance on tobacco control with increasing concerns about other risk factors included fostering an increasing awareness of tobacco-related issues, projects, and programs as well as developing collaborative relationships with organizations and institutions with complementary health-risk related objectives. Other recommendations focused on enhancing SPH leadership in the tobacco control field by developing standards and methodologies and translating research to practice. They included (1) developing standards for consistent tobacco control-related education to public health students, public health professionals, and other students and professionals; (2) developing a standardized method for evaluating tobacco-attributable factors and effects; and (3) conducting effectiveness trials of treatments known to be efficacious. Effectively addressing these perennial issues will enable SPH to enhance its leadership position and contribute greatly to research and education/training in tobacco control. All of these issues were factors in program planning for the second National STEP UP Academic Tobacco Workshop. For instance, reviews of particular research areas might be offered or facilitated as well as methods for developing collaborative partnerships and subsequent efforts. Steps toward the development of tobacco control education core competencies might be developed as well. The second National STEP UP Academic Tobacco Workshop-STEP UP to Sustain Tobacco Control and Prevention through Education and Research--was held on January 30-31, 2006. The topics of discussion ranged from use of secondary data to behavioral economics. More information about the workshop can be found at http://www.asph.org/ document.cfm?page=882. Attention to the recommendations that resulted from the planning meeting will provide a strategic platform from which ASPH and the public health community can continue to address the single greatest cause of preventable disease and death in the world.

Abstract
Sodium reduction is efficacious for primary prevention of hypertension, but the feasibility of achieving this effect is unclear. The objective of the paper is detailed analyses of adherence to and effects of the sodium reduction intervention among overweight adults in the Trials of Hypertension Prevention, Phase II. Sodium reduction (comprehensive education and counselling about how to reduce sodium intake) was tested vs no dietary intervention (usual care) for 36-48 months. A total of 956 white and 203 black adults, ages 30-54 years, with diastolic blood pressure 83-89 mmHg, systolic blood pressure (SBP) <140 mmHg, and body weight 110-165% of gender-specific standard weight were included in the study. At 36 months, urinary sodium excretion was 40.4 mmol/24 h (24.4%) lower in sodium reduction compared to usual care participants (P<0.0001), but only 21% of sodium reduction participants achieved the targeted level of sodium excretion below 80 mmol/24 h. Adherence was positively related to attendance at face-to-face contacts. Net decreases in SBP at 6, 18, and 36 months of 2.9 (P<0.001), 2.0 (P<0.001), and 1.3 (P=0.02) mmHg in sodium reduction vs usual care were associated with an overall 18% lower incidence of hypertension (P=0.048); were relatively unchanged by adjustment for ethnicity, gender, age, and baseline blood pressure, BMI, and sodium excretion; and were observed in both black and white men and women. From these beneficial but modest results with highly motivated and extensively counselled individuals, sodium reduction sufficient to favourably influence the population blood pressure distribution will be difficult to achieve without food supply changes.

Abstract
BACKGROUND Weight loss appears to be an effective method for primary prevention of hypertension. However, the long-term effects of weight loss on blood pressure have not been extensively studied. OBJECTIVE To present detailed results from the weight loss arm of Trials of Hypertension Prevention (TOHP) II. DESIGN Multicenter, randomized dinical trial testing the efficacy of lifestyle interventions for reducing blood pressure over 3 to 4 years. Participants in TOHP II were randomly assigned to one of four groups. This report focuses only on participants assigned to the weight loss (n = 595) and usual care control (n = 596) groups. PATIENTS Men and women 30 to 54 years of age who had nonmedicated diastolic blood pressure of 83 to 89 mm Hg and systolic blood pressure less than 140 mm Hg and were 110% to 165% of their ideal body weight at baseline. INTERVENTION The weight loss intervention included a 3-year program of group meetings and individual counseling focused on dietary change, physical activity, and social support MEASUREMENTS Weight and blood pressure data were collected every 6 months by staff who were blinded to treatment assignment RESULTS Mean weight change from baseline in the intervention group was -4.4 kg at 6 months, -2.0 kg at 18 months, and -0.2 kg at 36 months. Mean weight change in the control group at the same time points was 0.1, 0.7, and 1.8 kg. Blood pressure was significantly lower in the intervention group than in the control group at 6, 18, and 36 months. The risk ratio for hypertension in the intervention group was 0.58 (95% CI, 0.36 to 0.94) at 6 months, 0.78 (CI, 0.62 to 1.00) at 18 months, and 0.81 (CI, 0.70 to 0.95) at 36 months. In subgroup analyses, intervention participants who lost at least 4.5 kg at 6 months and maintained this weight reduction for the next 30 months had the greatest reduction in blood pressure and a relative risk for hypertension of 0.35 (CI, 0.20 to 0.59). CONCLUSIONS Clinically significant long-term reductions in blood pressure and reduced risk for hypertension can be achieved with even modest weight loss.

Abstract
BACKGROUND This paper examines participation rates and the association between participation and study outcomes (% energy from fat) among participants in the Women's Health Trial: Feasibility Study in Minority Populations, a randomized clinical trial to determine if ethnically and socioeconomically diverse women could be recruited and make significant dietary changes. METHODS Women (n = 2,208) were recruited from three clinical centers and randomized to either an intervention group or a control group. Multiple measures were collected at 6 months. RESULTS Participation rates for follow-up data collection activities were high (average participation 79%). Hispanics and lower educational groups participated significantly less (59% for Hispanics vs 86% for blacks and whites; 78% for lowest educational group vs 84% for highest educational group). Intervention participation significantly predicted change in percentage energy from fat (P < 0.001), accounting for an additional 8% of variance after background variables were controlled for. CONCLUSIONS These data suggest that intervention participation is positively related to dietary change, but they cannot rule out the possibility that other factors may influence both of these factors.

Abstract
BACKGROUND Patient delay in seeking health care for heart attack symptoms is a continuuing problem in the United States. METHODS Investigators conducted focus groups (N = 34; 207 participants) in major U.S. regions (NE, NW, SE, SW, MW) as formative evaluation to develop a multi-center randomized community trial (the REACT Project). Target groups included adults with previous heart attacks, those at higher risk for heart attack, and bystanders to heart attacks. There were also subgroups reflecting gender and ethnicity (African-American, Hispanic-American, White). FINDINGS Patients, bystanders, and those at higher risk expected heart attack symptoms to present as often portrayed in the movies, that is, as sharp, crushing chest pain rather than the more common onset of initially ambiguous but gradually increasing discomfort. Patients and those at higher risk also unrealistically judge their personal risk as low, understand little about the benefits of rapid action, are generally unaware of the benefits of using EMS/9-1-1 over alternative transport, and appear to need the "permission" of health care providers or family to act. Moreover, participants reported rarely discussing heart attack symptoms and appropriate responses in advance with health care providers, spouses, or family members. Women often described heart attack as a "male problem," an important aspect of their underestimation of personal risk. African-American participants were more likely to describe negative feelings about EMS/9-1-1, particularly whether they would be transported to their hospital of choice. CONCLUSIONS Interventions to reduce patient delay need to address expectations about heart attack symptoms, educate about benefits and appropriate actions, and provide legitimacy for taking specific health care-seeking actions. In addition, strategy development must emphasize the role of health care providers in legitimizing the need and importance of taking rapid action in the first place.

Abstract
OBJECTIVE This study evaluated physiological, neuroendocrine, and psychological status and functioning of patients with coronary artery disease in order to clarify their role in the expression of symptoms during myocardial ischemia (MI), and to establish repeatability of responses to mental stress. Design and methods of the study are presented. METHODS One hundred ninety-six coronary artery disease patients were examined during physical and mental stress tests in four hospitals. Eligibility criteria included narrowing of at least 50% in the diameter of at least one major coronary artery or verified history of myocardial infarction, and evidence of ischemia on an exercise treadmill test. Psychological, biochemical, and autonomic function data were obtained before, during, and after exposure to mental and exercise stressors during 2 or 3 half-days of testing. Ventricular function was assessed by radionuclide ventriculography, and daily ischemia by ambulatory electrocardiography. Sixty patients returned for a short-term mental stress repeatability study. Twenty-nine individuals presumed to be free of coronary disease were also examined to establish reference values for cardiac responses to mental stress. RESULTS Study participants were 41 to 80 years of age; 83 (42%) had a history of MI, 6 (3%) of congestive heart failure, and 163 (83%) of chest pain; 170 (87%) were men; and 90 (46%) had ischemia accompanied by angina during exercise treadmill testing. Ischemia during ambulatory monitoring was found in 35 of 90 (39%) patients with and 48 of 106 (45%) patients without angina during exercise-provoked ischemia. Intraobserver variability of ejection fraction changes during bicycle exercise and two mental stress tests (Speech and Stroop) was good (kappa = 1.0, .90, and .76, respectively; percent agreement = 100, 97.5, and 93.8%, respectively). Variability of assessed wall motion abnormalities during bicycle exercise was better (kappa, agreement = 85%) than during Speech or Stroop kappa and .57, percent agreement = 70% and 82.5%, respectively). CONCLUSIONS Study design, quality control data, and baseline characteristics of patients enrolled for a clinical study of symptomatic and asymptomatic myocardial ischemia are described. Lower repeatability of reading wall motion abnormalities during mental stress than during exercise may be due to smaller effects on wall motion and lack of an indicator for peak mental stress.

Abstract
School-based research requires a multi-level recruitment process to ensure an adequate sample. This article describes the High 5 Alabama recruitment experience at four levels; district, school, classroom and individual. One hundred percent of 28 schools across three districts and 108 classroom teachers contacted agreed to participate. Moderate success (69%) at the individual level, which required active parental consent for the student and parent to participate, resulted in 1,698 student/parent participants. An examination of differences between participants and nonparticipants revealed under-representation of a subsample of the population in the project sample. Suggestions obtained from project staff and teachers intended to enhance future school-based recruitment strategies include enlistment of a district advocate; meeting with teachers to solicit support; using incentives with students and teachers; direct contact with parents; having teachers keep rosters of students returning consent forms; and tailoring recruitment strategies for specific subpopulations.

Abstract
BACKGROUND The pathophysiology of mental stress-induced myocardial ischemia, which occurs at lower heart rates than during physical stress, is not well understood. METHODS AND RESULTS The Psychophysiological Investigations of Myocardial Ischemia Study (PIMI) evaluated the physiological and neuroendocrine functioning in unmedicated patients with stable coronary artery disease and exercise-induced ischemia. Hemodynamic and neurohormonal responses to bicycle exercise, public speaking, and the Stroop test were measured by radionuclide ventriculography, ECG, and blood pressure and catecholamine monitoring. With mental stress, there were increases in heart rate, systolic blood pressure, cardiac output, and systemic vascular resistance that were correlated with increases in plasma epinephrine. During exercise, systemic vascular resistance fell, and there was no relationship between the hemodynamic changes and epinephrine levels. The fall in ejection fraction was greater with mental stress than exercise. During mental stress, the changes in ejection fraction were inversely correlated with the changes in systemic vascular resistance. Evidence for myocardial ischemia was present in 92% of patients during bicycle exercise and in 58% of patients during mental stress. Greater increases in plasma epinephrine and norepinephrine occurred with ischemia during exercise, and greater increases in systemic vascular resistance occurred with ischemia during mental stress. CONCLUSIONS Mental stress-induced myocardial ischemia is associated with a significant increase in systemic vascular resistance and a relatively minor increase in heart rate and rate-pressure product compared with ischemia induced by exercise. These hemodynamic responses to mental stress can be mediated by the adrenal secretion of epinephrine. The pathophysiological mechanism involved are important in the understanding of the etiology of myocardial ischemia and perhaps in the selection of appropriate anti-ischemic therapy.

Abstract
The Women's Health Trial: Feasibility Study in Minority Populations (WHT:FSMP), a randomized trial of 2208 women, was conducted to investigate three questions. First, can women from minority and low-socioeconomic-status populations be recruited in numbers sufficient to evaluate a dietary intervention designed to lower fat intake. Second, the efficacy of a low fat, increased fruit/vegetable/ grain product intervention for reducing fat consumption. Third, will participation in the intervention lower plasma cholesterol and estradiol levels relative to the controls. The baseline results showed that an adequate number of minority and low SES women could be recruited to test the study hypotheses. A diverse study population of postmenopausal women consuming a high fat diet was recruited: 28% of participants were Black, 16% were Hispanic, 11% had less than a high school level of education, and 15.5% had household incomes of < $15,000.

Abstract
These analyses examined the relationship between fasting plasma lipids and several psychosocial factors in a healthy cohort of 5115 black and white men and women between the ages of 18 and 30. Primary analyses were performed within race/gender subgroups and were supplemented with analyses examining consistency of associations across these groups. After controlling for age, high density lipoprotein (HDL) decreased, triglycerides increased, low density lipoprotein (LDL) increased, and the total cholesterol/HDL cholesterol ratio increased with increasing level of education in black men. This pattern is, in general, opposite to that found in other groups, particularly white women, whose lipid profile was found to be less atherogenic the higher the education. These associations were strongly confounded with health behaviors. There was also a positive association between hostility and triglycerides in women but not in men. No significant association with any plasma lipid for either race or gender was found for Type A behavior, social support, or life events. Despite a narrow plasma lipid range in these young adults, these data support the conclusion that increasing education is associated with a less atherogenic plasma lipid profile, except in black men, for whom education is associated with a less favorable plasma lipid profile. Among other psychosocial factors, the only consistent finding was an inverse association between hostility and triglycerides in women.

Abstract
This research examines the influence of treatment attendance at two substance abuse outpatient treatment programs of the Birmingham Substance Abuse Homeless Project on substance abuse, homelessness, and unemployment outcomes with homeless persons abusing primarily crack cocaine. Results revealed that significant reductions across a one year period in alcohol use, cocaine use, and homelessness were more likely to occur in clients who attended an average of 4.1 treatment days per week (High attendance or Enhanced Care group) than clients who attended less than one day a week on the average (Low attendance or Usual Care and Medium attendance groups). These results are consistent with the literature suggesting that more intensive contact early in treatment results in better long-term outcome with cocaine abusers, but has now been demonstrated with homeless cocaine abusers who have additional problems associated with housing and employment.

Abstract
Trainees were randomized into four groups: (1) control; (2) consult; (3) liaison; or (4) consult-plus-liaison to evaluate the psychiatric knowledge gained after two different training programs for primary care residents. Consult was a 1-month rotation on the Psychiatry Consultation Service. Liaison consisted of 31-hour workshops over 1 year. Consult-plus-Liaison refers to both training programs, experienced in consecutive years. An oral examination was administered before and after training. The analysis of variance and tests of simple effects revealed significant training effects for both groups. The effect size of training was greater for residents exposed to both programs, compared with either one alone. The two different training programs were both effective in improving the psychiatric knowledge of primary care residents and exposure to both programs proved superior to either one alone.

Abstract
Associations between self-reported average daily alcohol intake and blood pressure were assessed in 5031 black and white men and women ages 18-30 from the Coronary Artery Risk Development in Young Adults Study (CARDIA). In general, intake was positively but weakly related to both systolic and diastolic blood pressure. Associations with systolic pressure were generally stronger than those with diastolic pressure. With average daily alcohol intake categorized as none, 0.1-9.9 ml, 10.0-19.9 ml, 20.0-29.9 ml, and 30.0+ ml, mean systolic pressure, adjusted for age, body mass index, education, smoking, and physical activity, increased progressively with increasing intake in black and white men and in white women. Mean diastolic pressure increased progressively with increasing intake only in white men and women, but was highest for those averaging 30.0+ ml per day in black women as well as white men and women. Mean pressures were also compared for those averaging 75.0+ ml per day (men) or 50.0+ ml per day (women) vs those reporting no intake. Differences in adjusted mean pressures for white men were 3.2 mmHg (95% confidence limits (CL) -0.3, 6.8) for systolic pressure and 1.7 mmHg (-1.6, 5.0) for diastolic pressure. In black men differences were 4.4 mmHg (1.4, 7.4) and 3.4 mmHg (0.6, 6.3), respectively. Differences in white women were 1.4 mmHg (-2.5, 5.3) for systolic pressure and 0.9 mmHg (-2.7, 4.5) for diastolic pressure and for black women, -0.2 mmHg (-4.3, 3.8) and 1.9 mmHg (-1.9, 5.8). Separate analyses in smokers and nonsmokers of the associations between alcohol intake and blood pressure suggested that associations may differ by smoking status in some sex-race groups.(ABSTRACT TRUNCATED AT 250 WORDS)
