BACKGROUND: Little is known in our country about regional differences in the treatment of acute coronary disease. OBJECTIVE: To analyze the behavior regarding the use of demonstrably effective regional therapies in acute coronary disease. METHODS: A total of 71 hospitals were randomly selected, respecting the proportionality of the country in relation to geographic location, among other criteria. In the overall population was regionally analyzed the use of aspirin, clopidogrel, ACE inhibitors / AT1 blocker, beta-blockers and statins, separately and grouped by individual score ranging from 0 (no drug used) to 100 (all drugs used). In myocardial infarction with ST elevation (STEMI) regional differences were analyzed regarding the use of therapeutic recanalization (fibrinolytics and primary angioplasty). RESULTS: In the overall population, within the first 24 hours of hospitalization, the mean score in the North-Northeast (70.5 ± 22.1) was lower (p <0.05) than in the Southeast (77.7 ± 29.5), Midwest (82 ± 22.1) and South (82.4 ± 21) regions. At hospital discharge, the score of the North-Northeast region (61.4 ± 32.9) was lower (p <0.05) than in the Southeast (69.2 ± 31.6), Midwest (65.3 ± 33.6) and South (73.7 ± 28.1) regions; additionally, the score of the Midwest was lower (p <0.05) than the South region. In STEMI, the use of recanalization therapies was highest in the Southeast (75.4%, p = 0.001 compared to the rest of the country), and lowest in the North-Northeast (52.5%, p <0.001 compared to the rest of the country). CONCLUSION: The use of demonstrably effective therapies in the treatment of acute coronary disease is much to be desired in the country, with important regional differences.BACKGROUND Little is known in our country about regional differences in the treatment of acute coronary disease.

OBJECTIVE To assess the impact of hyperglycemia in different age-groups of patients with acute myocardial infarction (AMI). RESEARCH DESIGN AND METHODS A total of 2,027 patients with AMI were categorized into one of five age-groups: <50 years (n = 301), ≥50 and <60 (n = 477), ≥60 and <70 (n = 545), ≥70 and <80 (n = 495), and ≥80 years (n = 209). Hyperglycemia was defined as initial glucose ≥115 mg/dL. RESULTS The adjusted odds ratios for hyperglycemia predicting hospital mortality in groups 1–5 were, respectively, 7.57 (P = 0.004), 3.21 (P = 0.046), 3.50 (P = 0.003), 3.20 (P < 0.001), and 2.16 (P = 0.021). The adjusted P values for correlation between glucose level (as a continuous variable) and mortality were 0.007, <0.001, 0.043, <0.001, and 0.064. The areas under the ROC curves (AUCs) were 0.785, 0.709, 0.657, 0.648, and 0.613. The AUC in group 1 was significantly higher than those in groups 3–5. CONCLUSIONS The impact of hyperglycemia as a risk factor for hospital mortality in AMI is more pronounced in younger patients.

Pseudo-myocardial infarction during an episode of herpes zoster

Roberto Alexandre Franken; Marcelo Franken

The patient arrived at the emergency unit with a history of acute myocardial infarction, for which she was treated. Without improvement in the pain, the patient developed heart failure and underwent a hemodynamic study, which showed normal coronary arteries and extensive ventricular impairment. During evolution, the clinical findings improved and herpes zoster appeared on the right shoulder. In a few months the clinical findings subsided, and the findings of the electrocardiogram, chest X-ray, and ventricular function were normal. The patient is currently asymptomatic.

Objectives: Elevated B-type natriuretic peptide (BNP) levels following acute myocardial infarction (AMI) are associated with adverse outcomes. The role of serial BNP monitoring after AMI has been poorly investigated. We aimed to evaluate the prognostic value of in-hospital serial BNP measurements in AMI patients. Methods: Patients with AMI (n = 1,924) were retrospectively evaluated. We selected patients with at least 2 in-hospital BNP measurements. The association between in-hospital mortality and BNP measurements (earliest, highest follow-up and the variation between measurements) were tested in multivariate models. Results: Serial BNP levels were determined in 176 patients. Compared to the rest of the population, these patients were older and had higher mortality rates. In the adjusted models, only the highest follow-up BNP remained associated with in-hospital death (odds ratio 1.06; 95% confidence interval, CI, 1.01-1.15; p = 0.014). Receiver-operating characteristic curve analysis demonstrated that the highest follow-up BNP was the best predictor of in-hospital death (area under the curve = 0.75; 95% CI 0.64-0.86). Conclusions: Serial BNP monitoring was performed in a high-risk subgroup of AMI patients. The highest follow-up BNP was a better predictor of short-term death than the baseline and in-hospital variation values. In AMI patients, a later in-hospital BNP assessment may be more useful than an early measurement.

ABSTRACT Objective: To evaluate the compliance rates to quality of care indicators along the implementation of an acute myocardial infarction clinical practice guideline. Methods: A clinical guideline for acute myocardial infarction was introduced on March 1st, 2005. Patients admitted for acute myocardial infarction from March 1st, 2005 to December 31st, 2012 (n=1,431) were compared to patients admitted for acute myocardial infarction before the implementation of the protocol (n=306). Compliance rates to quality of care indicators (ASA prescription on hospital admission and discharge, betablockers on discharge and door-to-balloon time) as well as the length of hospital stay and in-hospital mortality were compared before and after the implementation of the clinical guideline. Results: The rates of ASA prescription on admission, on discharge and of betablockers were higher after guideline implementation: 99.6% versus 95.8% (p<0.001); 99.1% versus 95.8% (p<0.001); and 95.9% versus 81.7% (p<0.001), respectively. ASA prescription rate increased over time, reaching 100% from 2009 to 2012. Door-to-balloon time after versus before implementation was of 86(32) minutes versus 93(51) (p=0.20). The length of hospital stay after the implementation versus before was of 6(6) days versus 6(4) days (p=0.34). In-hospital mortality was 7.6% (before the implementation), 8.7% between 2005 and 2008, and 5.3% between 2009 and 2012, (p=0.04). Conclusion: The implementation of an acute myocardial infarction clinical practice guideline was associated with an increase in compliance to quality of care indicators.

Purpose Patients with acute myocardial infarction (AMI) and respiratory impairment may be treated with either invasive or non-invasive mechanical ventilation (MV). However, there has been little testing of non-invasive MV in the setting of AMI. Our objective was to evaluate the incidence and associated clinical outcomes of patients with AMI who were treated with non-invasive or invasive MV. Methods This was a retrospective observational study in which consecutive patients with AMI (n = 1610) were enrolled. The association between exclusively non-invasive MV, invasive MV and outcomes was assessed by multivariable models. Results Mechanical ventilation was used in 293 patients (54% invasive and 46% exclusively non-invasive). In-hospital mortality rates for patients without MV, with exclusively non-invasive MV, and with invasive MV were 4.0%, 8.8%, and 39.5%, respectively (P<0.001). The median lengths of hospital stay were 6 (5.8–6.2), 13 (11.2–4.7), and 28 (18.0–37.9) days, respectively (P<0.001). Exclusively non-invasive MV was not associated with in-hospital death (adjusted HR = 0.90, 95% CI 0.40–1.99, P = 0.79). Invasive MV was strongly associated with a higher risk of in-hospital death (adjusted HR = 3.07, 95% CI 1.79–5.26, P<0.001). Conclusions In AMI setting, 18% of the patients required MV. Almost half of these patients were treated with exclusively non-invasive strategies with a favorable prognosis, while patients who needed to be treated invasively had a three-fold increase in the risk of death. Future prospective randomized trials are needed to compare the effectiveness of invasive and non-invasive MV for the initial approach of respiratory failure in AMI patients.

Background It is well known that the occurrence of bleeding increases in-hospital mortality in patients with acute coronary syndromes (ACS), and there is a good correlation between bleeding risk scores and bleeding incidence. However, the role of bleeding risk score as mortality predictor is poorly studied. Objective The main purpose of this paper was to analyze the role of bleeding risk score as in-hospital mortality predictor in a cohort of patients with ACS treated in a single cardiology tertiary center. Methods Out of 1,655 patients with ACS (547 with ST-elevation ACS and 1,118 with non-ST-elevation ACS), we calculated the ACUITY/HORIZONS bleeding score prospectively in 249 patients and retrospectively in the remaining 1,416. Mortality information and hemorrhagic complications were also obtained. Results Among the mean age of 64.3 ± 12.6 years, the mean bleeding score was 18 ± 7.7. The correlation between bleeding and mortality was highly significant (p < 0.001, OR = 5.296), as well as the correlation between bleeding score and in-hospital bleeding (p < 0.001, OR = 1.058), and between bleeding score and in-hospital mortality (adjusted OR = 1.121, p < 0.001, area under the ROC curve 0.753, p < 0.001). The adjusted OR and area under the ROC curve for the population with ST-elevation ACS were, respectively, 1.046 (p = 0.046) and 0.686 ± 0.040 (p < 0.001); for non-ST-elevation ACS the figures were, respectively, 1.150 (p < 0.001) and 0.769 ± 0.036 (p < 0.001). Conclusions Bleeding risk score is a very useful and highly reliable predictor of in-hospital mortality in a wide range of patients with acute coronary syndromes, especially in those with unstable angina or non-ST-elevation acute myocardial infarction.

Background In high-income temperate countries, the number of hospitalizations for heart failure (HF) and acute myocardial infarction (AMI) increases during the winter. This finding has not been fully investigated in low- and middle-income countries with tropical and subtropical climates. We investigated the seasonality of hospitalizations for HF and AMI in Sao Paulo (Brazil), the largest city in Latin America. Methods This was a retrospective study using data for 76,474 hospitalizations for HF and 54,561 hospitalizations for AMI obtained from public hospitals, from January 2008 to April 2015. The average number of hospitalizations for HF and AMI per month during winter was compared to each of the other seasons. The autoregressive integrated moving average (ARIMA) model was used to test the association between temperature and hospitalization rates. Findings The highest average number of hospital admissions for HF and AMI per month occurred during winter, with an increase of up to 30% for HF and 16% for AMI when compared to summer, the season with lowest figures for both diseases (respectively, HF: 996 vs. 767 per month, p<0.001; and AMI: 678 vs. 586 per month, p<0.001). Monthly average temperatures were moderately lower during winter than other seasons and they were not associated with hospitalizations for HF and AMI. Interpretation The winter season was associated with a greater number of hospitalizations for both HF and AMI. This increase was not associated with seasonal oscillations in temperature, which were modest. Our study suggests that the prevention of cardiovascular disease decompensation should be emphasized during winter even in low to middle-income countries with tropical and subtropical climates.
