RESUMO
BACKGROUND: Current evidence shows that single-stage treatment of concomitant choledocholithiasis and cholelithiasis is as effective and safe as two-stage treatment. However, several studies suggest that single-stage approach requires shorter hospitalization time and is more cost-effective than the two-stage approach, even though it requires considerable training. This study aimed to evaluate the implementation of a protocol for managing concomitant choledocholithiasis and cholelithiasis using single-stage treatment. METHODS: A prospective cohort study of patients diagnosed with cholelithiasis and choledocholithiasis who were treated with the single-stage treatment - transcystic instrumentation, choledocotomy or intraoperative endoscopic retrograde cholangiopancreatography (ERCP) - between September 2010 and June 2017 was assessed. The primary outcomes were complications, hospital stay, operative time and recurrence rate. RESULTS: 164 patients were enrolled. 141 (86%) were operated laparoscopically. Preoperatively diagnosed stones were not found by intraoperative imaging or disappeared after "flushing" in 38 patients (23.2%). Surgical approach was transcystic in 45 patients (27.41%), choledochotomy in 74 (45.1%), intraoperative ERCP in 4 (2.4%), and bilioenteric derivation in 3 (1.8%). Mean hospitalization stay was 4.4 days. Mean operative time was 166 min 27 patients (16.5%) had complications and 1 patient was exitus (0.6%). Recurrence rate was 1.2%. CONCLUSIONS: Single-stage approach is a safe and effective management option for concomitant cholelithiasis and choledocolithiasis. Furthermore, a significant number of common bile duct stones pass spontaneously to duodenum or can benefit from a transcystic approach, with presumable low morbidity and cost-efficiency.

OBJECTIVE: To derive and validate a set of functions to predict coronary heart disease (CHD) and stroke, and validate the Framingham-REGICOR function. METHOD: Pooled analysis of 11 population-based Spanish cohorts (1992-2005) with 50,408 eligible participants. Baseline smoking, diabetes, systolic blood pressure (SBP), lipid profile, and body mass index were recorded. A ten-year follow-up included re-examinations/telephone contact and cross-linkage with mortality registries. For each sex, two models were fitted for CHD, stroke, and both end-points combined: model A was adjusted for age, smoking, and body mass index and model B for age, smoking, diabetes, SBP, total and HDL cholesterol, and for hypertension treatment by SBP, and age by smoking and by SBP interactions. RESULTS: The 9.3-year median follow-up accumulated 2973 cardiovascular events. The C-statistic improved from model A to model B for CHD (0.66 to 0.71 for men; 0.70 to 0.74 for women) and the combined CHD-stroke end-points (0.68 to 0.71; 0.72 to 0.75, respectively), but not for stroke alone. Framingham-REGICOR had similar C-statistics but overestimated CHD risk. CONCLUSIONS: The new functions accurately estimate 10-year stroke and CHD risk in the adult population of a typical southern European country. The Framingham-REGICOR function provided similar CHD prediction but overestimated risk.

PURPOSE: There is limited prospective evidence at population scale of the impacts of lifestyle and surrogate measures of general and abdominal adiposity on the transition of a metabolically healthy (absence of a metabolic disorder) overweight/obese (MHOO) phenotype to a metabolically abnormal overweight/obese (MAOO) phenotype. Therefore, we determined the relationship between 10-year body mass index (BMI), waist circumferences (WC), waist to height ratio (WHtR), and lifestyle changes and the transition of the MHOO phenotype. METHODS: We conducted a prospective population-based study of 3,052 male and female Spaniards aged 25-74 years who were followed from 2000 through 2009. Diet and leisure-time physical activity were recorded on validated questionnaires. Weight, height, WC, blood lipids, glycemia, and blood pressure were measured. All variables were obtained at baseline (BL) and follow-up (FL). Participants with a BMI ≥ 25 kg/m(2) and free from hypercholesterolemia, hypertriglyceridemia, diabetes, hypertension, and low HDL and high LDL cholesterol levels were characterized as the MHOO phenotype. A composite healthy lifestyle index (HLI) was constructed by including temporary changes in 3 lifestyle variables (diet, leisure-time physical activity, and smoking). RESULTS: Initially, 20.8% of subjects had the MHOO phenotype; 49.2% of these shifted to MAOO phenotype. In multivariate analysis, changes in BMI, WC, WHtR were positively associated (p = 0.004, p = 0.018, and p = 0.016, respectively) with this transition. One unit increase in the HLI was associated with a 33% lower risk (p = 0.025) to the MAOO phenotype transition after adjusting for age, sex, educational level, and baseline energy intake, BMI, WC, and WHtR. CONCLUSIONS: The presence of metabolic disorders in the MHOO phenotype is predicted by an increase in anthropometric surrogate measures of general and abdominal adiposity. In contrast, a healthy lifestyle protects against a transition to the MAOO phenotype.

INTRODUCTION AND OBJECTIVES: Myocardial infarction (MI) incidence and case fatality trends are highly informative but relatively untested at the population level. The objective of this work was to estimate MI incidence and case fatality in the Girona population aged 35-74 years, and to determine their 30-year trends (1990-2019). METHODS: The REGICOR (Girona Heart Registry) monitored MI incidence and case fatality rates from 1990 to 2008. For the period 2008 to 2019, we linked discharges from Girona hospitals (n=4 974 977) and mortality registry (n=70 405) during this period. Our linkage algorithm selected key MI diagnostic codes and removed duplicates. Estimates from the linkage algorithm and the REGICOR registry were compared using chi-square tests for overlapping years (2008-2009). We estimated the annual percent change (APC) of standardized MI incidence and 28-day case fatality, and analyzed their trends using joinpoint regression. RESULTS: MI incidence and case fatality estimates were similar in the linkage algorithm and the REGICOR registry. We observed significant decreasing trends in the incidence of MI. The trend was APC, -0.96% (95% confidence interval (95%CI), -1.4 to -0.53) in women from 1990 to 2019 and -4.2% (95%CI, -5.5 to -3.0) in men from 1994 to 2019. The largest decrease in case fatality was -3.8% (95%CI, -5.1 to -2.5) from 1995 to 2003 in women and -2.4% (95%CI, -2.9 to -1.9) from 1995 to 2004 in men, mainly due to prehospital case fatality declines: -1.8% (95%CI, -2.6 to -1.1) in men and -3.2% (95%CI, -4.6 to -1.8) in women. CONCLUSIONS: In Girona, MI incidence and case fatality decreased between 1990 and 2019. The incidence showed a slow but continuous decrease while case fatality only stabilized in the last decade, particularly in women.
RESUMO
OBJECTIVE: The contribution of human cytomegalovirus (HCMV) to vascular disease may depend on features of the immune response not reflected by the detection of specific antibodies. Persistent HCMV infection in healthy blood donors has been associated with changes in the distribution of NK cell receptors (NKR). The putative relationship among HCMV infection, NKR distribution, subclinical atherosclerosis, and coronary heart disease was assessed. METHODS AND RESULTS: NKR expression was compared in acute myocardial infarction (AMI) patients (n=70) and a population-based control sample (n=209). The relationship between NKR expression and carotid intima-media thickness (CIMT) in controls (n=149) was also studied. HCMV infection was associated with higher proportions of NKG2C+ and LILRB1+ NK and T-cells. In contrast, only LILRB1+ NK and CD56+ T-cells were found to be increased in AMI patients, independent of age, sex, conventional vascular risk factors, and HCMV seropositivity. Remarkably, LILRB1 expression in NK and T-cells significantly correlated with CIMT in controls. CONCLUSIONS: The association of overt and subclinical atherosclerotic disease with LILRB1+ NK and T-cells likely reflects a relationship between the immune challenge by infections and cardiovascular disease risk, without attributing a dominant role for HCMV. Our findings may lead to the identification of novel biomarkers of vascular disease.

Women with myocardial infarction (MI) have shown a 28-day survival disadvantage compared with men. However, results were less consistent when considering long-term mortality in 28-day survivors. The aim was to estimate the trends for sex-related differences in the three endpoints considered for this study: (1) 28-day mortality or severe ventricular dysfunction (acute pulmonary oedema or cardiogenic shock) during the hospital stay, (2) 28-day mortality and (3) two-year cardiovascular mortality or non-fatal MI in 28-day survivors after a first MI. A cohort of 3,982 consecutive patients with first Q-wave MI admitted to a university tertiary reference hospital between 1978 and 2007 was followed for 2 years. Short-term prognosis improved in women over the studied period; similar rates were observed in both sexes in the 2000s. After adjusting for age, co-morbidities and anterior location of MI, female sex had an odds ratio=1.71 (95% confidence interval [CI] 1.34-2.17) of short-term severe MI or death over the studied period. Overall, sex differences in long-term prognosis remained similar over the studied period (hazard ratio=1.40; 95% CI 1.02-1.91). In conclusion, short-term prognosis improved over the past 30 years for first Q-wave MI patients, becoming similar for both men and women in the most recent decade. Long-term prognosis did not improve in either men or women, indicating that secondary prevention should be reinforced to achieve consistent reductions in the number of cardiovascular events.

BACKGROUND: We sought to analyze the trends in first Q-wave acute myocardial infarction (AMI) case fatality from 1978 to 2007 in a population-based hospital register, to determine the variables related to these changes, and to assess the effectiveness of current AMI management. METHODS: Population-based hospital registry included patients with first Q-wave AMI aged 25 to 74 years admitted between 1978 and 2007. Sociodemographic and clinical characteristics, treatments, and procedures used during hospital stay, and 28-day case fatality were recorded. Logistic regression was used for multivariate analysis of six 5-year periods. RESULTS: The 30-year study included 3,982 patients. Mean 28-day case fatality was 8.96%, with a decreasing trend from 16.6% in the first 5-year period to 4.7% in the sixth (P for trend < .001). Study period was independently associated with case fatality. Case-fatality reduction attributable to pharmacologic treatments was 51% overall; in 24-hour survivors, pharmacologic treatments and broad use of invasive procedures explained 39% and 38%, respectively, of the difference between the observed case fatality in 2003-2007 and 1978-1982. CONCLUSION: A dramatic decrease in 28-day case fatality occurred during this 30-year period and was mainly related to the use of antiplatelet drugs, ß-blockers, thrombolysis, and invasive procedures. These data support the current guidelines for the management of acute coronary syndrome.

OBJECTIVE: To determine the effect of age and study period on coronary heart disease (CHD) risk attributable to cardiovascular risk factors. METHODS: A cohort of cardiovascular disease (CVD)-free randomly participants from Girona (Spain) aged 35-74 years recruited in 1995 and 2000 and followed for an average of 6.9 years. A survey conducted in the same area in 2005 was also used for the analysis. Smoking, hypertension, diabetes, sedentary lifestyle, obesity, total cholesterol > or = 240 mg/dl, low-density lipoprotein (LDL) cholesterol > or = 160 mg/dl, and high-density lipoprotein cholesterol <40 mg/dl were the risk factors considered. The composite end-point included myocardial infarction, angina pectoris, and CHD death. RESULTS: LDL cholesterol had the highest potential for CHD prevention between 35 and 74 years [42% (95% Confidence Interval: 23,58)]. The age-stratified analysis showed that the population attributable risk (PAF) for smoking was 64% (30,80) in subjects < 55 years; for those > or = 55 years, the PAF for hypertension was 34% (1,61). The decrease observed between 1995 and 2005 in the population's mean LDL cholesterol level reduced that PAF in all age groups. CONCLUSION: Overall, LDL cholesterol levels had the highest potential for CHD prevention. Periodic PAF recalculation in different age groups may be required to adequately monitor population trends.

BACKGROUND AND OBJECTIVES: The value of body mass index in the prognosis of patients with ischemic heart disease is not well defined. The objective of our study was to determine the association of body mass index with classic and emergent cardiovascular risk factors and with intra-hospital and 6-months mortality. PATIENTS AND METHODS: We conducted a prospective, multicenter study with a 6-months follow-up. We included 1063 patients between the ages of 25-75 years old who were consecutively admitted to the hospital within the first 24 hours of the onset of symptoms between years 2001 and 2003. We determined demographic and anthropometric variables, as well as classic and emergent factors of risk, clinical variables and the treatment administered. We carried out a univariate and multivariate analysis. RESULTS: The percentage of patients with overweight or obesity in this population was 73.56%. Overweight and obesity were associated with classical risk factors, except for smoking, and emergent risk factors. Body mass index was not associated with short-or mid-term prognosis. CONCLUSIONS: Body mass index is not a useful anthropometric measure to determine the prognosis of patients after a first myocardial infarction.

BACKGROUND AND OBJECTIVE: The REACH Registry is the largest worldwide designed to obtain information on cardiovascular risk factor control and preventive treatment in a population who have, or are at risk of having, symptoms of atherothrombosis. The objective of this study is to show the results of cardiovascular events obtained in a sample of the Spanish population at one year follow-up and intervention. MATERIAL AND METHOD: The REACH Spain registry is a prospective cohort study of subjects with vascular risk factors (ORF) for atherothrombosis or with symptomatic vascular disease (VD): coronary artery disease (CAD) and/or cerebrovascular disease (CVD) and/or peripheral artery disease (PAD). The main outcome measures were rates of all-cause mortality, cardiovascular (CV) death, and the overall combined CV death, myocardial infarction (MI), or stroke and CV hospitalization at one year follow-up. RESULTS: In Spain 2,516 patients were recruited and 2,252 completed one year follow-up, the mean age was 68,1 (73,8% men), 11,6% of subjects with ORF and 88,5% with VD, 55% with CAD, 33% with CVD and 17% with PAD. The annual rate of all-cause mortality in VD and ORF groups were 3,57% and 1,98% (NS) respectively, while for CV death they were 2,69% and 0,62% (P<.05) and for overall combined CV death myocardial infarction (MI), or stroke and CV hospitalization they were 15,34% and 5,47% (P=.0001). The annual rate of CV death for CAD, CVD and PAD groups were 3,47%, 2,78% and 1,46% respectively, and for the overall combined CV death, myocardial infarction (MI) , or stroke and CV hospitalization they were 18,52%, 13,75% and 14,52%. These event rates increased with the number of symptomatic arterial disease locations from 0,1,2 or 3 for CV death (0,62%, 2,46%, 3,55% and 4,32%, respectively P<.05) and for overall combined CV death myocardial infarction (MI), or stroke and CV hospitalization (5,50%, 4,18%, 20,59% y 19,40%, respectively P<.0001). At one year follow-up, 82,8% of the patients were with at least one antiplatelet drug and 86,2% were receiving lipid-lowering agents. CONCLUSIONS: The REACH Spain Registry at one year follow-up in patients with atherothrombotic disease or at risk of having symptoms of atherothrombosis shows a high rate of all-cause mortality and of overall combined major CV events, which is becoming higher as the number of symptomatic arterial disease locations increases.

Complete ventricular septal defects (VSD) can be congenital (estimated prevalence 0.5% in live births) (Roguin N, et al. High prevalence of muscular ventricular septal defect in neonates. J Am Coll Cardiol 1995;26:1545-1548) or may be a complication of acute myocardial infarction (estimated incidence in the era of thrombolysis 0.2%) [Crenshaw BS, et al. Risk factors, angiographic patterns, and outcomes in patients with ventricular septal defect complicating acute myocardial infarction. GUSTO-I (Global Utilization of Streptokinase and TPA for Occluded Coronary Arteries) Trial Investigators. Circulation 2000;101:27-32]. In this paper, we report two unique cases of partial VSD.

INTRODUCTION AND OBJECTIVES: To assess the validity of the original low-risk SCORE function without and with high-density lipoprotein cholesterol and SCORE calibrated to the Spanish population. METHODS: Pooled analysis with individual data from 12 Spanish population-based cohort studies. We included 30 919 individuals aged 40 to 64 years with no history of cardiovascular disease at baseline, who were followed up for 10 years for the causes of death included in the SCORE project. The validity of the risk functions was analyzed with the area under the ROC curve (discrimination) and the Hosmer-Lemeshow test (calibration), respectively. RESULTS: Follow-up comprised 286 105 persons/y. Ten-year cardiovascular mortality was 0.6%. The ratio between estimated/observed cases ranged from 9.1, 6.5, and 9.1 in men and 3.3, 1.3, and 1.9 in women with original low-risk SCORE risk function without and with high-density lipoprotein cholesterol and calibrated SCORE, respectively; differences were statistically significant with the Hosmer-Lemeshow test between predicted and observed mortality with SCORE (P < .001 in both sexes and with all functions). The area under the ROC curve with the original SCORE was 0.68 in men and 0.69 in women. CONCLUSIONS: All versions of the SCORE functions available in Spain significantly overestimate the cardiovascular mortality observed in the Spanish population. Despite the acceptable discrimination capacity, prediction of the number of fatal cardiovascular events (calibration) was significantly inaccurate.

BACKGROUND: To assess the reliability and accuracy of the Framingham coronary heart disease (CHD) risk function adapted by the Registre Gironí del Cor (REGICOR) investigators in Spain. METHODS: A 5-year follow-up study was completed in 5732 participants aged 35-74 years. The adaptation consisted of using in the function the average population risk factor prevalence and the cumulative incidence observed in Spain instead of those from Framingham in a Cox proportional hazards model. Reliability and accuracy in estimating the observed cumulative incidence were tested with the area under the curve comparison and goodness-of-fit test, respectively. RESULTS: The Kaplan-Meier CHD cumulative incidence during the follow-up was 4.0% in men and 1.7% in women. The original Framingham function and the REGICOR adapted estimates were 10.4% and 4.8%, and 3.6% and 2.0%, respectively. The REGICOR-adapted function's estimate did not differ from the observed cumulated incidence (goodness of fit in men, p = 0.078, in women, p = 0.256), whereas all the original Framingham function estimates differed significantly (p<0.001). Reliabilities of the original Framingham function and of the best Cox model fit with the study data were similar in men (area under the receiver operator characteristic curve 0.68 and 0.69, respectively, p = 0.273), whereas the best Cox model fitted better in women (0.73 and 0.81, respectively, p<0.001). CONCLUSION: The Framingham function adapted to local population characteristics accurately and reliably predicted the 5-year CHD risk for patients aged 35-74 years, in contrast with the original function, which consistently overestimated the actual risk.

BACKGROUND AND OBJECTIVE: The REACH Registry is the largest worldwide registry designed to obtain information on cardiovascular risk factor control and preventive treatment in a population who have, or are at high risk of having, symptoms of atherothrombosis. The objective of this study is to show the results obtained in a sample of the Spanish population included in that registry. PATIENTS AND METHOD: Registry of consecutive patients who have risk factors only (RFO) for atherothrombosis or who have symptomatic vascular disease (VD): coronary heart disease (CHD) and/or cerebrovascular disease (CVD) and/or peripheral artery disease (PAD). Cardiovascular risk factor control and the use of antithrombotic and lipid lowering therapy were evaluated. RESULTS: In Spain 2,515 patients were recruited; 297 had RFO and 2,218 had VD: 61.4% with CHD, 36.6% with CVD and 18.7% with PAD. The rates of noncontrolled blood pressure, glycemia, total cholesterol and triglyceride levels in the RFO group compared to those of the VD group were: 76.5% vs 57.1% (p < 0.005), 61.6% vs 30.9% (p < 0.005), 55.7% vs 41.3% (p < 0.005) and 45.5% vs 35.1% (p < 0.005), respectively. The antiplatelet therapy rate in these two groups was 44.1% vs 86.5% (p < 0.005), the anticoagulant therapy rate was 11.4% vs 12.6% (no significant difference) and statin therapy rate was 65.2% vs 65.6% (no significant difference). Significant differences were found among the CHD, CVD and PAD groups as regards noncontrolled blood pressure rate (49.8%. 57.1% and 67.1%, respectively p < 0.005), total cholesterol control rate (41.3%, 48.2% and 50.2% respectively, p < 0.005) as well as antiplatelet therapy rate (86.5%. 83.2% and 81.6% respectively p < 0.005) and statin therapy rate (78.2%. 51.9% and 57.8% respectively p < 0.005). CONCLUSIONS: Cardiovascular risk factor control in subjects at high risk of atherothrombosis or who have established VD is poor. It is poorer in primary prevention and in PAD patients. Whilst the use of statins is insufficient, the use of antithrombotic medication is acceptable in secondary prevention but considerably lacking in primary prevention.

INTRODUCTION AND OBJECTIVES: Atrial fibrillation (AF) is the most common clinically significant cardiac arrhythmia. P-wave duration and interatrial blocks (IAB) have been reported to be associated with AF. Our aim was to determine the individual and combined association of P-wave duration and advanced IAB morphology with AF. METHODS: We designed an age-, sex-, and survey-matched case-control study nested in a population-based cohort (REGICOR: REgistre GIroní del COR). Two different surveys recruited a total of 9380 participants from 1999 to 2005; all participants were invited to a second examination between 2009 and 2013. For the present study, we selected participants aged 25 to 79 years with follow-up through the end of the study. All electrocardiograms were analyzed by 2 observers to determine P-wave duration and morphology (normal, partial, or advanced IAB). RESULTS: The median follow-up was 7.12 years. Eighty participants presented with AF, had a legible baseline electrocardiogram, and were included in the study, along with 160 controls. P-wave duration and the presence of partial or advanced IAB were associated with AF. When P-wave duration and morphology were considered together, only P-wave duration (≥ 110 milliseconds) showed an independent and strong association with AF. The odds ratio for AF of P-wave duration between 110-119, 120-129 and ≥ 130 milliseconds vs < 110 milliseconds were 5.33; 95%CI, 1.74-16.33, 5.08; 95%CI, 1.73-14.90 and 5.44; 95%CI, 1.95-15.15, respectively. CONCLUSIONS: A P-wave longer than 110 milliseconds increases the risk of AF. Advanced IAB morphology did not seem to provide an additional AF risk beyond that of P-wave duration.

Both mortality due to cerebrovascular disease in individuals aged under 85 years and mortality due to acute myocardial infarction (AMI) are lower in women than men. In contrast, the age-adjusted 28-day case fatality rate after a first AMI is 20% higher in women, particularly in countries where the incidence of AMI is low. In Spain, the case fatality rate is elevated in women hospitalized for a first AMI, but not in those with other forms of coronary heart disease. The pattern of mortality observed after symptom onset, which shows that death is delayed in women, suggests that the mechanism of death is different in the two sexes. The substantial variation that exists in the way results are adjusted and presented make it very difficult to compare the findings of different studies. Relative to men, women with AMI are 10 years older, reach hospital one hour later on average, more frequently have a comorbid condition (mainly diabetes and hypertension), progress to a more serious clinical state, and have a higher adjusted 28-day mortality risk. Moreover, the treatment given to women during the acute phase is less aggressive. A change in healthcare workers' attitudes is needed so that women with acute coronary syndromes can be identified earlier, thereby increasing the use of diagnostic and therapeutic procedures to a level that corresponds to the greater severity of AMI observed in women at presentation.

BACKGROUND: Evidence is lacking about the effectiveness of risk reduction interventions in patients with asymptomatic peripheral arterial disease. OBJECTIVES: This study aimed to assess whether statin therapy was associated with a reduction in major adverse cardiovascular events (MACE) and mortality in this population. METHODS: Data were obtained from 2006 through 2013 from the Catalan primary care system's clinical records database (SIDIAP). Patients age 35 to 85 years with an ankle-brachial index ≤0.95 and without clinically recognized cardiovascular disease (CVD) were included. Participants were categorized as statins nonusers or new-users (first prescription or represcribed after at least 6 months) and matched 1:1 by inclusion date and propensity score for statin treatment. Conditional Cox proportional hazards modeling was used to compare the groups for the incidence of MACE (myocardial infarction, cardiac revascularization, and ischemic stroke) and all-cause mortality. RESULTS: The matched-pair cohort included 5,480 patients (mean age 67 years; 44% women) treated/nontreated with statins. The 10-year coronary heart disease risk was low (median: 6.9%). Median follow-up was 3.6 years. Incidence of MACE was 19.7 and 24.7 events per 1,000 person-years in statin new-users and nonusers, respectively. Total mortality rates also differed: 24.8 versus 30.3 per 1,000 person-years, respectively. Hazards ratios were 0.80 for MACE and 0.81 for overall mortality. The 1-year number needed to treat was 200 for MACE and 239 for all-cause mortality. CONCLUSIONS: Statin therapy was associated with a reduction in MACE and all-cause mortality among participants without clinical CVD but with asymptomatic peripheral arterial disease, regardless of its low CVD risk. The absolute reduction was comparable to that achieved in secondary prevention.

BACKGROUND: Diagnosis of unrecognized myocardial infarction (UMI) remains an open question in epidemiological and clinical studies, inhibiting effective secondary prevention of myocardial infarction. We aimed to determine the prevalence and incidence of Q-wave UMI in asymptomatic individuals aged 35 to 74years, and to ascertain the positive predictive value (PPV) of asymptomatic Q-wave to diagnose UMI. METHODS: Two population-based cross-sectional studies were conducted, in 2000 (with 10-year follow-up) and in 2005. A baseline electrocardiogram was obtained for each participant. Imaging techniques (echocardiography, cardiac magnetic resonance imaging, and myocardial perfusion single-photon emission computerized tomography) were used to confirm UMI in patients with asymptomatic Q-wave. RESULTS: The prevalence of confirmed Q-wave UMI in the 5580 participants was 0.18% (95% confidence interval [CI]: 0.10-0.33) and the incidence rate was 27.1 Q-wave UMI per 100,000person-years. The proportion of confirmed Q-wave UMI with respect to all prevalent MI was 8.1% (95% CI: 4.4-14.2). The PPV of asymptomatic Q-wave to diagnose Q-wave UMI was 29.2% (95% CI: 18.2-43.2%) overall, but much higher (75%, 95% CI: 40.9-92.9%) in participants with 10-year CHD risk ≥10%, compared to lower-risk participants. CONCLUSION: Opportunistic identification of asymptomatic Q-waves by routine electrocardiogram overestimates actual Q-wave UMI, which represents 8% to 13% of all myocardial infarction in the population aged 35 to 74years. This overestimation is particularly high in the population at low cardiovascular risk. In epidemiological studies and in clinical practice, diagnosis of a pathologic Q-wave in asymptomatic patients requires detailed analysis of imaging tests to confirm or rule out myocardial necrosis.

INTRODUCTION AND OBJECTIVES: A patient's social circumstances at the time when acute myocardial infarction (AMI) symptoms first appear might influence survival. Our objectives were to study the living conditions, the location where symptoms started, the type of symptoms, and the delay before action was taken in patients with AMI who survived more than one hour, and to analyze the relationship between these variables and mortality in different time periods. PATIENTS AND METHOD: Population-based observational cohort study carried out in 1997-1998. Main data source: Registre Gironí del Cor (REGICOR). Death certificates provided information on patients who died before they could be included in the register. The patients' demographic characteristics, lifestyle, clinical history, electrocardiographic abnormalities, cardiac enzyme levels, treatment, and diagnosis were recorded. Mortality before and during hospitalization, and overall mortality at 28 days were studied. RESULTS: Of the 1,097 patients included, 274 (24.97%) died before reaching hospital, 171 (15.58%) died in hospital, and 652 (59.4%) were alive at 28 days. Mortality was lower in patients who went directly to hospital (OR = 0.32, 95% CI, 0.17-0.59). Mortality at 28 days was higher in those with atypical symptoms (OR = 5.52, 95% CI, 2.90-10.50), and in those who lived in an institution (OR = 9.47, 95% CI, 1.05-84.9). CONCLUSIONS: In the absence of specially equipped ambulances, AMI patients who went directly to the hospital or who had typical symptoms had a better chance of survival both before hospitalization and at 28 days. In contrast, 28-day mortality was higher in institutionalized patients.

INTRODUCTION AND OBJECTIVES: Analysis of the effect of treatment in observational studies is complex due to differences between treated and nontreated patients. Calculating the probability of receiving treatment conditioned on relevant covariates (propensity score [PS]) has been proposed as a method to control for these differences. We report an application of PS to assess the association between reperfusion treatment and 28-day case fatality in patients with acute myocardial infarction (AMI). METHOD: We describe the procedure used to calculate PS for receiving reperfusion treatment, and different strategies to analyze the association between PS and case fatality with regression modeling and matching. Data were from a population-based registry of 6307 patients with AMI in Spain during 1997-98. RESULTS: The PS for reperfusion was calculated in 5622 patients. In the multivariate analysis, reperfusion was associated with lower case fatality (OR = 0.59; 95% confidence interval [95% CI]: 0.46-0.77). When PS was included as a covariate, this association became non- significant (OR = 0.76; 95% CI: 0.57-1.01). In the subgroup of matched patients with a similar PS (n = 3138), treatment was not associated with case fatality (OR = 0.95; 95% CI: 0.72-1.26). When the influence of cases with missing data on PS was controlled for, reperfusion treatment was associated with lower fatality (OR = 0.66; 95% CI: 0.55-0.80). CONCLUSIONS: Calculating propensity score is a method that controls for differences between treated and nontreated patients. This score has limitations when matching is incomplete and when data are missing. Results of the present example suggest that reperfusion treatment reduces AMI case fatality.
