Protein-Energy Supplementation in Early-Life Decreases the Odds of Mental Distress in Later Adulthood in Guatemala

The prevalence of mental health concerns is growing worldwide, along with lack of access to and receipt of needed treatment. Current gaps in treatment provision have led to exploring alternative methods of prevention, with research linking nutrition and mental health, of particular relevance in low- and middle-income countries, with a high prevalence of undernutrition. To examine whether exposure to a protein-energy nutritional supplement during the first 1000 d of life decreased odds of mental distress in adulthood among men and women in Guatemala compared with receiving a low energy-no protein supplement or supplementation outside the 1000-d window. Data from participants (n = 1249) in a longitudinal cohort protein-energy supplementation trial (early-life, supplementation data from 1969 to 1977, ages 0­7 y; life course, outcome data from 2017­2018 follow-up, ages 40­57 y) were analyzed for associations between nutrition in the first 1000 d and mental distress in adulthood (WHO Self- Reporting Questionnaire 20 [SRQ-20]), controlling for early-life variables and current life stress; life course variables (e.g. education) were examined as potential mediators of this relation. Generalized linear mixed models and zero-inflated Poisson generalized linear mixed models were utilized. Both partial and full supplementation with Atole during the first 1000 d were associated with 63% (95% CI: 0.16, 0.87) and 56% (95% CI: 0.19, 1.03) lower odds, respectively, of experiencing mental distress in adulthood. Did not differ by sex. These inverse relations remained relatively unchanged (partial OR = 0.34 [95% CI: 0.14, 0.83]; full OR = 0.38 [95% CI: 0.16, 0.92]) after controlling for early-life and life course variables, including life stress. Protein-energy supplementation during the first 1000 d of life in Guatemala, where undernutrition is prevalent, may reduce the prevalence of later mental distress in adulthood. This effect appears to occur directly, rather than indirectly, through pathways of life course variables such as education, wealth, and marital status.

Differential influences of early growth and social factors on young children's cognitive performance in four low-and-middle-income birth cohorts (Brazil, Guatemala, Philippines, and South Africa).

BACKGROUND: Studies relating childhood cognitive development to poor linear growth seldom take adequate account of social conditions related to both, leading to a focus on nutrition interventions. We aimed to assess the roles of both biological and social conditions in determining early childhood cognition, mediated by birthweight and early linear growth. METHODS: After exploratory structural equation modelling to identify determining factors, we tested direct and indirect paths to cognitive performance through birthweight and child height-for-age at 2 years, assessed between 4 and 8.5 years of age among 2448 children in four birth cohort studies in low-and-middle-income countries (Brazil, Guatemala, Philippines and South Africa). Determinants were compared across the cohorts. FINDINGS: Three factors yielded excellent fit, comprising birth endowment (primarily maternal age and birth order), household resources (crowding, dependency) and parental capacity (parental education). We estimated their strength together with maternal height in determining cognitive performance. Percentage shares of total effects of the four determinants show a marked transition from mainly biological determinants of birth weight (birth endowment 34%) and maternal height (30%) compared to household resources (25%) and parental capacity (11%), through largely economic determinants of height at 2 years (household resources (60%) to cognitive performance being predominantly determined by parental capacity (64%) followed by household resources (29%). The largely biological factor, birth endowment (maternal age and birth order) contributed only 7% to childhood cognitive performance and maternal height was insignificant. In summary, the combined share of social total effects (household resources and parental capacity) rises from 36∙2% on birth weight, to 78∙2% on height for age at 24 m, and 93∙4% on cognitive functioning. INTERPRETATION: Across four low- and middle-income contexts, cognition in childhood is influenced more by the parental capacity of families and their economic resources than by birth weight and early linear growth. Improving children's cognitive functioning requires multi-sectoral interventions to improve parental education and enhance their economic wellbeing, interventions that are known to improve also early childhood growth.

Parental childhood growth and offspring birthweight: pooled analyses from four birth cohorts in low and middle income countries.

OBJECTIVE: Associations between parental and offspring size at birth are well established, but the relative importance of parental growth at different ages as predictors of offspring birthweight is less certain. Here we model parental birthweight and postnatal conditional growth in specific age periods as predictors of offspring birthweight. METHODS: We analyzed data from 3,392 adults participating in four prospective birth cohorts and 5,506 of their offspring. RESULTS: There was no significant heterogeneity by study site or offspring sex. 1SD increase in maternal birthweight was associated with offspring birthweight increases of 102 g, 1SD in maternal length growth 0-2 year with 46 g, and 1SD in maternal height growth Mid-childhood (MC)-adulthood with 27 g. Maternal relative weight measures were associated with 24 g offspring birth weight increases (2 year- MC) and 49 g for MC-adulthood period but not with earlier relative weight 0-2 year. For fathers, birthweight, and linear/length growth from 0-2 year were associated with increases of 57 and 56 g in offspring birthweight, respectively but not thereafter. CONCLUSIONS: Maternal and paternal birthweight and growth from birth to 2 year each predict offspring birthweight. Maternal growth from MC-adulthood, relative weight from 2-MC and MC-adulthood also predict offspring birthweight. These findings suggest that shared genes and/or adequate nutrition during early life for both parents may confer benefits to the next generation, and highlight the importance of maternal height and weight prior to conception. The stronger matrilineal than patrilineal relationships with offspring birth weight are consistent with the hypothesis that improving the early growth conditions of young females can improve birth outcomes in the next generation.

Multicausal etiology of anemia among women of reproductive age in Vietnam.

BACKGROUND/OBJECTIVES: Anemia is a significant public health concern, especially among women and young children. An improved understanding of the complex etiology of anemia is crucial for developing appropriate prevention strategies. This paper examines the determinants of anemia in a large sample of Vietnamese women of reproductive age (WRA). METHODS: We included baseline data from 4986 WRA participating in a randomized controlled trial (PRECONCEPT). Hemoglobin (Hb) concentrations were measured with Hemocue. Plasma ferritin (Fe), retinol binding protein (RBP) and markers of inflammation were assessed using the ELISA technique. We used multivariate logistic regression to describe associations with anemia and structural equation modeling (SEM) to characterize direct and indirect pathways influencing Hb concentrations. RESULTS: Prevalence of anemia, iron deficiency (Fe <12 µg/l), insufficient iron stores (Fe<30 µg/l) and iron deficiency anemia was 19.7, 3.5, 14.4 and 1.9%, respectively. Ferritin concentration (0.29 per log-mg/dl), being an ethnic minority (-0.24 compared with Kinh), number of children (-0.17) and socioeconomic status (0.09) were directly associated with Hb concentration (P<0.05). Similarly, RBP was directly (0.27 per mg/dl) associated with Hb and also indirectly (0.09 mg/dl) with ferritin. Hookworm infection was indirectly associated with Hb (-0.11) through RBP and ferritin. CONCLUSION: These findings illustrate the complex etiology of anemia and provide a useful framework for designing, targeting and evaluating appropriate strategies for the prevention and control of anemia. Contrary to expectations, iron deficiency accounted for a very small proportion of anemia in Northern Vietnam.

The public health challenge of early growth failure in India.

Recent recognition of the early onset and high prevalence of wasting (30%) and stunting (20%) among infants 0-5 months in India draws attention to the need to understand the causes and develop prevention strategies. Such growth failure has dire consequences in the short (increased mortality) and long-term (loss of human capital and increased risk of chronic diseases). Food interventions before 6 months will increase morbidity/mortality through contamination in settings of poor sanitation and hygiene. Waiting to improve nutrition only after the initiation of complementary feeding at 6 months is a missed opportunity and may permanently alter life trajectory and potential. This underscores the importance of maternal nutrition. Iron and folic acid and protein energy supplementation during pregnancy are interventions that can improve maternal nutrition and birth outcomes. Maternal supplementation during lactation should be considered as a means to improve maternal and child outcomes, although the evidence needs strengthening. Support and counseling are also required to improve maternal diets and promote exclusive breastfeeding. Programs focused on improving maternal nutrition across the continuum of preconception, pregnancy and lactation are likely to have the greatest impact as mothers are central gatekeepers to the health and future of their children.

Bigger babies born to women survivors of the 1959-1961 Chinese famine: a puzzle due to survival selection?

The Chinese Famine of 1959-1961 caused up to 30 million deaths. It varied in intensity across China and affected rural areas disproportionately. Data from the China-U.S. Collaborative Project for Neural Tube Defect Prevention on 31, 449 women (born 1957-1963) and their offspring birth size were recorded in 1993-1996. We used a measure of famine intensity at county level based on the size of famine-born cohorts relative to cohorts preceding and following the famine in a difference-in-difference model that compared offspring birth size of pre-famine (1957-1958; exposed between 0.5 and 4.5 years), famine (1959-1961; prenatal and up to 2.5 years) and post-famine (1962; some exposed in early pregnancy) cohort groups to that of the unexposed 1963 cohort. The model corrected for age and cohort trends and estimated associations between maternal famine exposure and offspring birth size for the average level of famine intensity across counties, and included adjustment for clustering. In rural areas and in pre-famine and famine cohorts, exposure to famine was associated with larger weight (69 g; 95% CI 30, 108), length (0.3 cm; 95% CI -0.0, 0.5) and birth body mass index (0.1 kg/m2; 95% CI 0.0, 0.2). In urban areas, however, exposure to famine was not associated with offspring birth size. Our findings in rural areas suggest that severe and prolonged famine leads to larger newborn size in the offspring of mothers exposed to famine in utero and during the first few years of life; less severe famine in urban areas however, appeared to have no impact. The markedly increased mortality in rural areas may have resulted in the selection of hardier mothers with greater growth potential, which becomes expressed in their offspring.

Iodine levels and thyroid hormones in healthy pregnant women and birth weight of their offspring.

INTRODUCTION: The fetus is most vulnerable to severe iodine deficiency and hypothyroidism during pregnancy. The effects of mild iodine deficiency and subclinical hypothyroidism are poorly known. The present study assesses the association between thyroid hormones (TH)s and urinary iodine concentration (UIC) in healthy pregnant women and the birth weight of their children. METHODS: About 657 pregnant women were recruited in Sabadell and followed until delivery. The association between THs during the first trimester, UIC during the first and third trimesters, and birth weight was studied in 557, 251, and 528 mother-newborn pairs respectively, using linear and logistic regression models adjusted for potential confounders. Only 239 women had all the data available (thyroid function and UIC at the first and third trimesters). Six percent of newborns were classified as small for gestational age (SGA). RESULTS: The median UIC was 95 and 104 microg/l during the first and third trimesters respectively. Women with the third trimester UICs between 100 and 149 microg/l had lower risk of having an SGA newborn than women with UICs below 50 microg/l (adjusted OR (95%CI): 0.15 (0.03-0.76). There was no significant reduction in SGA among mothers with higher UICs. Lower free thyroxine and higher TSH levels during the first trimester were not associated with birth weight or SGA. Nevertheless, the analyses were repeated including only those women with all the data available, and high TSH levels became statistically significantly associated with lower birth weight and higher risk of SGA. CONCLUSIONS: The present study suggests that iodine status during pregnancy may be related to prenatal growth in healthy women.

Size at birth, infant, early and later childhood growth and adult body composition: a prospective study in a stunted population.

BACKGROUND: Pre-natal and post-natal growth are associated with adult body composition, but the relative importance of growth in different periods of childhood is still unclear, particularly in stunted populations. METHODS: We studied 358 women and 352 men measured as children in 1969-77 in four villages in Guatemala, and re-measured as adults in 2002-04 (mean age 32.7 years). We determined the associations of body mass index (BMI) and length at birth, and changes in BMI and length during infancy (0-1.0 year) and early (1.0-3.0 years) and later (3.0-7.0 years) childhood, with adult BMI ((a)BMI), percentage of body fat ((a)PBF), abdominal circumference ((a)AC) and fat-free mass ((a)FFM). RESULTS: Prevalence of stunting was high (64% at 3 years; HAZ < -2SD). Obesity (WHZ > 2SD) prevalence in childhood was <2%, while overweight prevalence in adulthood was 52%. BMI at birth was positively associated with (a)BMI and (a)FFM while length at birth was positively associated with (a)AC and (a)FFM. Increased BMI in infancy and later childhood were positively associated with all four adult body composition measures; associations in later childhood with fatness and abdominal fatness were stronger than those with (a)FFM. Change in length during infancy and early childhood was positively associated with all four adult body composition outcomes; the associations with (a)FFM were stronger than those with fat mass. CONCLUSIONS: Increases in BMI between 3.0 and 7.0 years had stronger associations with adult fat mass and abdominal fat than with (a)FFM; increases in length prior to age 3.0 years were most strongly associated with increases in (a)FFM.

Country development and the association between parity and overweight.

INTRODUCTION: Parity is associated with overweight and obesity in developed countries and has been related to maternal depletion in poor developing countries. However, the literature from developing countries is limited and may not represent current stages of development. METHODS: We analyzed data from 50 Demographic and Reproductive Health Surveys conducted between 1992 and 2003. We examined the association between parity (proxied by number of live births) and overweight (body mass index (BMI)> or =25 kg/m(2)) in relation to level of country wealth and development. RESULTS: The odds ratio (OR) for overweight comparing women with at least four live births to women with one live birth was >1.0 in 38 of the 50 countries studied. The median OR was >1.0 in all regions studied and highest in North Africa/West Asia, where all countries had OR >1.0. Country wealth and development were both positively associated with the ORs. CONCLUSIONS: The importance of parity as a predictor of overweight increases with national economic development and wealth. Policy implications might include the development and implementation of programs to prevent excessive gestational weight gain and promote postpartum weight loss via dietary change and physical activity, concomitant with exclusive breastfeeding.

Construction of the World Health Organization child growth standards: selection of methods for attained growth curves.

The World Health Organization (WHO), in collaboration with a number of research institutions worldwide, is developing new child growth standards. As part of a broad consultative process for selecting the best statistical methods, WHO convened a group of statisticians and child growth experts to review available methods, develop a strategy for assessing their strengths and weaknesses, and discuss methodological issues likely to be faced in the process of constructing the new growth curves. To select the method(s) to be used, the group proposed a two-stage decision-making process. First, to select a few relevant methods based on a list of set criteria and, second, to compare the methods using available tests or other established procedures. The group reviewed 30 methods for attained growth curves. Using the pre-defined criteria, a few were selected combining five distributions and two smoothing techniques. Because the number of selected methods was considered too large to be fully tested, a preliminary study was recommended to evaluate goodness of fit of the five distributions. Methods based on distributions with poor performance will be eliminated and the remaining methods fully tested and compared.

Ultrasound measurement of fetal size in rural Guatemala.

OBJECTIVES: To describe the fetal growth pattern of a population from rural Guatemala and determine when during gestation growth faltering becomes evident. METHODS: Ultrasound examinations were conducted for 319 women. Femur length (FL), biparietal diameter (BPD), abdominal (AC) and head circumference (HC) were compared with reference values. RESULTS: FL and AC were similar to reference values throughout gestation. BPD and HC were below the 50th percentile by 30 weeks' gestation and below the 10th percentile later in gestation. We expected all four dimensions to show marked growth restriction during gestation. Measurement differences may explain the results but would call into question the value of cross-study comparisons. Infants born small for gestational age were small in all measures as early as 15 weeks. CONCLUSIONS: Fetal growth faltering begins in early gestation among infants who were born small. The lack of deviation from reference data for FL and AC requires further clarification.

Full breast-feeding for at least four months has differential effects on growth before and after six months of age among children in a Mexican community.

This study examines the relationship between breast-feeding and growth from 0 to 6 and 6 to 20 mo among 185 children in a Mexican community. Infants from a previous 6-mo longitudinal study were followed up for additional anthropometric measurements at a mean age of 19.9 mo. Size at 6 mo and at follow-up were modeled as outcomes of whether infants were fully breast-fed (exclusively or predominantly breast-fed) for at least 4 mo, controlling for size at birth and 6 mo, respectively, and potential confounders. From birth to 6 mo, fully breast-fed infants had ponderal index increments of 0.07 units larger (P = 0.04) than comparison infants. There were no differences in weight. For length, an interaction between full breast-feeding and socioeconomic status (SES) was found, with fully breast-fed infants of low SES growing more than comparison infants, whereas the opposite was seen at upper SES levels. From 6 to 20 mo, fully breast-fed infants had weight and length increments of 0.53 cm (P < 0.001) and 0.72 kg (P = 0.01) smaller than those of comparison infants. For ponderal index, an interaction between mother's education and breast-feeding revealed an inverted U-shaped response across levels of education. Additionally, logistic regressions of monthly breast-feeding on lagged measurements revealed that relatively heavier infants had higher odds of being fully breast-fed at 2 and 3 mo. Our findings indicate that the benefits of full breast-feeding on growth may be most pronounced early in life. Further research of unmeasured confounders may explain the association of full breast-feeding with slower growth beyond 6 mo.

Growth in indigenous and nonindigenous Chilean schoolchildren from 3 poverty strata.

OBJECTIVES: This study sought to determine whether the short stature of Mapuche children, an indigenous group in Chile, reflects poverty or genetic heritage and whether the international reference population, derived from studies of US children of mostly European origin, is appropriate for assessing growth failure in indigenous peoples of the Americas. METHODS: The study assessed 768 schoolchildren of Mapuche and non-Mapuche ancestry, aged 6 to 9 years, living under conditions of extreme, medium, and low poverty. RESULTS: Growth retardation was strongly related to poverty in both ethnic groups. Within poverty levels, there were no significant differences in stature between ethnic groups, and in low-poverty areas in Santiago, the capital city, mean stature was only slightly less than in the reference population. CONCLUSIONS: Poverty, not ancestry, explains the short stature of Mapuche children, and use of the international reference to assess growth in this population is appropriate.

Early nutrition and later adiposity.

The objective was to review whether nutrition during pregnancy and the first 3 y of life predisposes individuals to be fatter as adults. The roles of undernutrition, overnutrition and breastfeeding were considered. The evidence that poor nutrition in early life is a risk factor for increased fatness later in life is inconclusive. Overnutrition, as proxied by high birthweight or gestational diabetes, on the other hand, is associated with subsequent fatness. Two large, well-conducted studies in developed countries suggest that breastfeeding has a protective effect. Nutrition in early life has a demonstrable but small impact on adult obesity.

Determinants of fasting glucose in young Guatemalan adults.

OBJECTIVE: To examine correlates of fasting glucose, a precursor for type 2 diabetes mellitus, in young adults in Guatemala, a country undergoing an epidemiologic transition. DESIGN: Cross-sectional. METHODS: Anthropometric, lifestyle, dietary, serum lipid, and socioeconomic characteristic data were collected on 189 men and 201 women (mean age 24.4 years) born in four villages in Eastern Guatemala. We used linear regression to identify parsimonious predictive models, including 2-way interactions. RESULTS: In men, mean fasting glucose was 87.3 mg/dL (SD 10.2); our model explained 30% of variance. Body mass index (BMI), abdomen-to-hip ratio (AHR), and total cholesterol showed graded positive effects. BMI and AHR interacted (P<.001); men with high BMI and high AHR had the highest fasting glucose levels. No dietary factors independently predicted fasting glucose. In women, mean fasting glucose was 83.9 mg/dL (SD 8.5); 22% of variance was explained by BMI, energy-adjusted fat intake, physical activity, birth village, and current residence (rural/urban). BMI and fasting glucose were positively related. Urban residence interacted with birth village (P=.06) and physical activity (P=.13). CONCLUSIONS: The major conclusion drawn from this study is that increased adiposity, even among lean individuals, is the largest environmental predictor of fasting glucose. Prevention and control of obesity in young adults in transitioning countries are key strategies for the prevention of diabetes.

Short-term benefits of catch-up growth for small-for-gestational-age infants.

BACKGROUND: Recent studies suggest that small newborns who present rapid postnatal growth may have an increased risk of chronic diseases in adulthood. On the other hand, it is widely assumed that catch-up growth is desirable for low birthweight children, but the literature on this subject is limited. METHODS: Population-based cohort study in southern Brazil, with 3582 children examined at birth, 20 and 42 months of age. Catch-up growth from 0 to 20 months was related to subsequent risks of hospital admissions and mortality. RESULTS: Children who were small-for-gestational-age (SGA) but presented substantial weight gain (> or =0.66 z-score) up to the age of 20 months had 65% fewer subsequent hospital admissions than other SGA children (5.6% versus 16.0%; P < 0.001). Mortality to age 5 years was 75% lower (3 versus 13 per 1000, a non-significant difference based on a small number of deaths) for rapid-growing SGA children compared to the remaining SGA children. Their admission and mortality rates were similar to those observed for children born with an appropriate birthweight for their gestational age (AGA). Similar positive effects of rapid growth were found for AGA children. CONCLUSION: There appear to be definite benefits associated with catch-up growth. Growth promotion efforts for infants who are born small should take into account their possible short- and long-term consequences.

Therapeutic effects of oral zinc in acute and persistent diarrhea in children in developing countries: pooled analysis of randomized controlled trials.

BACKGROUND: Zinc deficiency is prevalent in children in developing countries. Supplemental zinc provides therapeutic benefits in diarrhea. OBJECTIVE: We sought to measure the effect of supplemental zinc given with oral rehydration therapy during recovery from acute or persistent diarrhea. DESIGN: We conducted pooled analyses including all available published and unpublished randomized controlled trials of the effects of supplementary oral zinc in children aged <5 y with acute or persistent diarrhea. We used Cox survival regression analysis to evaluate the overall effect of zinc on continuation of diarrhea and possible differential effects in subgroups divided by sex, age, weight-for-height, and initial plasma zinc concentration. Dichotomous outcomes were analyzed by logistic regression. To assess the effects of excluding studies without original data from the pooled analyses, effect-size was estimated for all studies by using random-effects models. RESULTS: Zinc-supplemented children had a 15% lower probability of continuing diarrhea on a given day (95% CI: 5%, 24%) in the acute-diarrhea trials and a 24% lower probability of continuing diarrhea (95% CI: 9%, 37%) and a 42% lower rate of treatment failure or death (95% CI: 10%, 63%) in the persistent-diarrhea trials. In none of the subgroup analyses were the 2 subgroups of each pair significantly different from each other; however, in persistent diarrhea there tended to be a greater effect in subjects aged <12 mo, who were male, or who had wasting or lower baseline plasma zinc concentrations. CONCLUSION: Zinc supplementation reduces the duration and severity of acute and persistent diarrhea.

Co-occurrence of nutrition problems in Honduran children.

We used data from the 1996 Honduras National Micronutrient Survey to investigate the co-occurrence of vitamin A deficiency (VAD), anemia and stunting in a representative sample of Honduran children 1-5 y old. Observed frequencies of co-occurrence were compared with frequencies expected by chance in children 12-35.9 mo old (n = 633) and 36-59.9 mo old (n = 610) for the three possible two-way combinations of the problems and the three-way combination. Observed frequencies were greater than expected frequencies for all eight comparisons, and all comparisons except for that of stunting and anemia in younger children were significant. The observed frequency of the three-way co-occurrence was 8.4% compared with an expected co-occurrence of 8.1% in younger children (P: < 0.05) and 4.8% compared with 4.2%, respectively, in older children (P: < 0.001). Although there was statistical evidence for co-occurrence, differences between expected and observed prevalences were small for most comparisons. Our findings suggest that having one or two problems does not appreciably increase the probability of having another. The efficiency of nutrition interventions aimed at these conditions would not be improved by targeting children with any one of the conditions; rather, the three conditions should be treated as virtually independent when designing programs. Replication of this study in other settings is warranted.

[Clinical practice guidelines of the Spanish Society of Cardiology on unstable angina/infarction without ST elevation]. / Guías de práctica clínica de la Sociedad Española de Cardiología en la angina inestable/infarto sin elevación ST.

This paper up-dates the Clinical Guidelines for Unstable Angina/Non Q wave Myocardial Infarction of the Spanish Society of Cardiology. Due to the increased efficacy of adequate management in the early phases, it has been considered necessary to include recommendations for the pre Hospital and Emergency department phase. Prehospital management. Patients with thoracic pain compatible with myocardial ischemia should be transferred to Hospital as quickly as possible and an ECG tracing performed. Initial management includes rest, sublingual nitroglycerin and aspirin. In the Emergency department. Immediate clinical attention and accessibility to a defibrillator should be available. If ECG tracing discloses ST elevation reperfusion strategy is to be implemented immediately. If no ST elevation is present, the probability of myocardial ischemia and risk factor evaluation is essential for adequate management. A simplified risk stratification classification is presented, that also determines the most adequate site for admission: Coronary Care Unit if high risk factors are present, Cardiology ward for the intermediate risk patient and ambulatory treatment if low risk. Management in Coronary Care Unit. Includes routine ECG monitoring and analgesia. Antithrombotic and anti ischemic treatment include new indication for GP IIb-IIIa and Low molecular weight heparins. Coronary arteriography and revascularisation are recommended, if refractory or recurrent angina, left ventricles dysfunction or other complications are present. Management in the ward is based on adequate chronic medical treatment, risk stratification, and secondary prevention strategy. Coronary arteriography before discharge must be considered in the light of the result of non-invasive tests.
