RESUMEN

Social support has been associated with coronary artery disease (CAD), particularly in individuals who have sustained a cardiovascular event. This study investigated the relationship between social support and subclinical CAD among 1067 healthy middle-aged men and women. Social support was assessed with validated social integration and emotional attachment measures. Subclinical CAD was assessed as a coronary artery calcium score (CACS) using computed tomography. There was no association between social support and CACS in men. In women, low social support was strongly linked to cardiovascular risk factors, high levels of inflammatory markers, and CACS > 0. In a logistic regression model, after adjustment for 12 cardiovascular risk factors, the odds ratio (95% confidence intervals) for CACS > 0 in women with the lowest social integration, emotional attachment, and social support groups (reference: highest corresponding group) were 2.47 (1.23-5.12), 1.87 (0.93-3.59), and 4.28 (1.52-12.28), respectively. Using a machine learning approach (random forest), social integration was the fourth (out of 12) most important risk factor for CACS > 0 in women. Women with lower compared to higher or moderate social integration levels were about 14 years older in "vascular age". This study showed an association between lack of social support and subclinical CAD in middle-aged women, but not in men. Lack of social support may affect the atherosclerotic process and identify individuals vulnerable to CAD events.

RESUMEN

BACKGROUND: The extent and the severity of acute myocardial infarction (MI) is decreasing. Out-of-hospital medical management before the hospital admission could alter clinical presentation in acute MI. We used a large national patient register to investigate the relation between previous medication use (aspirin, beta-blockers, angiotensin-converting enzyme [ACE] inhibitors, and statins) and the risk of presenting with ST-segment elevation MI (STEMI) or non-STEMI. METHODS: We included 103 459 consecutive patients from the Swedish Register of Information and Knowledge About Swedish Heart Intensive Care Admissions (RIKS-HIA) admitted between January 1, 1996, and December 31, 2006, with a first acute MI. RESULTS: The patients with STEMI (43.5% of the total) were younger, had less prior cardiovascular disease, and used fewer medications before hospitalization. Of the STEMI patients, 61.4% had used no medication vs 45.9% of the patients with non-STEMI. After multiple adjustments, use of aspirin, beta-blockers, ACE inhibitors, and statins before hospitalization were all associated with substantially lower odds of presenting with STEMI. Furthermore, the risk decreased with the number of previous medications, and the use of 3 or more medications was associated with a multiply adjusted odds ratio of presenting with STEMI of 0.48 (99% confidence interval, 0.44-0.52) compared with no medications at admission. CONCLUSIONS: Use of aspirin, beta-blockers, ACE inhibitors, or statins before hospital admission in patients with a first acute MI is associated with substantially less risk of presenting with STEMI. The risk decreases with the increasing number of these medications used before acute MI, underlining the benefit of preventive medication in high-risk patients.

RESUMEN

BACKGROUND: Red blood cell (RBC) transfusion is common during cardiac surgical procedures. Empiric crossmatching, without attempting to estimate individual transfusion requirements is typical. We hypothesized that a clinical prediction tool could be developed to estimate the number of units of RBCs needed for coronary artery bypass grafting (CABG) surgery. STUDY DESIGN AND METHODS: With institutional review board approval, detailed demographic, risk factor, and transfusion data of primary elective CABG procedures (n=5887) from September 1, 1993, to June 20, 2002, were studied and the data set was divided into development and validation subgroups. Multivariable ordinal logistic regression was used to develop and validate transfusion risk factors, assign them a relative weight, and create a model to stratify patients into groups depending on predicted need for 0, 2, 4, or more than 4 RBC units. The model was compared with current standard practice of crossmatching 4 RBC units in terms of observed blood product usage over the study period. RESULTS: Demographic and transfusion risk factor variables in the development (n=3876) and validation (n=2011) data sets were similar. The predictive value of the model was good for the development and validation groups, with a c-index of 0.79 and 0.78, respectively. Applying the predictive model reduced the number of crossmatches by 30% without underproviding RBC units and increased the percentage of patients crossmatched exactly for the required number of units from 11% to 21%. CONCLUSIONS: Predictive factors for RBC transfusion were identified and used to construct a clinical tool to conserve blood bank resources without increasing patient risk.

RESUMEN

BACKGROUND: Many studies have compared women and men for symptoms of acute myocardial infarction (AMI), but findings have been inconsistent, largely because of varying inclusion criteria, different study populations, and different methods. OBJECTIVE: The purpose of this study was to analyze gender differences in symptoms in a well-defined, population-based sample of women and men who experienced a first AMI. METHODS: Information on symptoms was collected from the medical charts of all patients with a first AMI, aged 25 to 74 years, who had taken part in the INTERGENE (Interplay Between Genetic Susceptibility and Environmental Factors for the Risk of Chronic Diseases) study. INTERGENE was a population-based research program on risk factors for cardiovascular disease. Medical charts were reviewed for each patient to determine the symptoms of AMI, and the prevalence of each symptom was compared according to sex. RESULTS: The study included 225 patients with a first AMI: 52 women and 173 men. Chest pain was the most common symptom, affecting 88.5% (46/52) of the women and 94.8% (164/173) of the men, with no statistically significant difference between the sexes. Women had significantly higher rates of 4 symptoms: nausea (53.8% [28/52] vs 29.5% [51/173]; age-adjusted odds ratio [OR] = 2.78; 95% CI, 1.47-5.25), back pain (42.3% [22/52] vs 14.5% [25/173]; OR = 4.29; 95% CI, 2.14-8.62), dizziness (17.3% [9/52] vs 7.5% [13/173]; OR = 2.60; 95% CI, 1.04-6.50), and palpitations (11.5% [6/52] vs 2.9% [5/173]; OR = 3.99; 95% CI, 1.15-13.84). No significant gender differences were found in the proportions of patients experiencing arm or shoulder pain, diaphoresis, dyspnea, fatigue, neck pain, abdominal pain, vomiting, jaw pain, or syncope/lightheadedness. No significant differences were found in the duration, type, or location of chest pain. The medical charts listed numerically more symptoms in women than in men; 73.1% (38/52) of the women but only 48.0% (83/173) of the men reported >3 symptoms (age-adjusted OR = 3.26; 95% CI, 1.62-6.54). CONCLUSIONS: Chest pain is the most common presenting symptom in both women and men with AMI. Nausea, back pain, dizziness, and palpitations were significantly more common in women. Women as a group displayed a greater number of symptoms than did men.

RESUMEN

AIMS: Coronary heart disease (CHD) mortality rates have been falling in Sweden since the 1980s. We used the previously validated IMPACT CHD model to examine how much of the mortality decrease in Sweden between 1986 and 2002 could be attributed to medical and surgical treatments, and how much to changes in cardiovascular risk factors. METHODS AND RESULTS: The IMPACT mortality model was used to combine and analyse data on uptake and effectiveness of cardiological treatments and risk factor trends in Sweden. The main data sources were official statistics, national quality of care registers, published trials and meta-analyses, and national population surveys. Between 1986 and 2002, CHD mortality rates in Sweden decreased by 53.4% in men and 52.0% in women aged 25-84 years. This resulted in 13 180 fewer deaths in 2002. Approximately 36% of this decrease was attributed to treatments in individuals and 55% to population risk factor reductions. Adverse trends were seen for diabetes and overweight. CONCLUSION: More than half of the substantial CHD mortality decrease in Sweden between 1986 and 2002 was attributable to reductions in major risk factors, mainly a large decrease in total serum cholesterol. These findings emphasize the value of a comprehensive strategy that promotes primary prevention and evidence-based medical treatments, especially secondary prevention.

RESUMEN

PURPOSE: The aim of this study was to evaluate how relatives of patients with an ostomy rated the various aspects of care, how they perceived the quality of the care provided, and how they ranked their involvement in the care. Patients' satisfaction was also sought, particularly their perception of relatives' involvement. DESIGN: Descriptive cross-sectional. SETTINGS AND SUBJECTS: The study comprised a colostomy group (32 pairs) and an ileostomy group (28 pairs). All patients attended a stoma outpatient clinic. METHODS: Quality of care was assessed using the identity-oriented dimension of the validated questionnaire Qualityof Care from the Patient's Perspective. Questionnaires were mailed to patients and their relatives. RESULTS: Relatives and patients in both study groups considered most topics covered by the questionnaire to be important. Half of the patients with an ileostomy and their relatives and approximately 30% of those in the colostomy group were dissatisfied with the information they received, however. Moreover, a greater proportion (41-89%) of the patients were unhappy with the opportunities they were offered to participate in the decision-making process. Patients with an ileostomy and their relatives tended to be more dissatisfied with the quality of care than the colostomy group, but the difference was not statistically significant. CONCLUSION: The topics covered by the questionnaire were considered important to both patients and their relatives. Information and counseling offered by the ET nurses and the colorectal surgeons were judged to be unsatisfactory, indicating the need for frequently assessing and improving general standards of quality of care.

RESUMEN

AIM: This paper reports a study whose aim was to assess the quality of care in ostomy patients seen from a patient perspective. BACKGROUND: A stoma operation causes profound changes in a patient's life because of resulting physical damage, disfigurement, loss of bodily function, and change in personal hygiene. Such changes are a cause of major concern for patients and raise important issue for the quality of care. METHODS: The study group comprised patients who had undergone a colostomy for rectal cancer or an ileostomy for ulcerative colitis, all attending a stoma outpatient clinic. Quality of care was assessed using the identity-oriented dimension of the validated questionnaire 'Quality of Care from the Patient's Perspective'. Forty-two ileostomy and 49 colostomy patients completed the questionnaire. RESULT: While the vast majority of patients in both groups thought that most topics in the questionnaire were important, most rated many aspects of their quality of care as unsatisfactory. One-third of the colostomy patients and one-half of the ileostomy patients were dissatisfied with the information they received about the results of medical examinations and laboratory tests, and an even higher proportion was dissatisfied with their opportunities to participate in the decision-making process or to discuss sexual matters. Stoma-related complications, which occurred in 71% of the ileostomy patients and in 43% of the colostomy patients, had no impact on these results. CONCLUSION: Information and counselling for patients having ostomies, both on the part of specialist nurses and colorectal surgeons, appeared to deficient, suggesting that standards for quality of care require continuous evaluation and revision.
