Itamar Souza Santos et al. Alessandra Carvalho Goulart Rodrigo Martins Brandão Rafael Caire de Oliveira Santos … Márcio Sommer Bittencourt Débora Sitnik Alexandre Costa Pereira Carlos Alberto Pastore Nelson Samesima Paulo Andrade Lotufo Isabela Martins Bensenor

Background:

Information about post-acute coronary syndrome (ACS) survival have been mostly short-term findings or based on specialized, cardiology referral centers.

Objectives:

To describe one-year case-fatality rates in the Strategy of Registry of Acute Coronary Syndrome (ERICO) cohort, and to study baseline characteristics as predictors.

Methods:

We analyzed data from 964 ERICO participants enrolled from February 2009 to December 2012. We assessed vital status by telephone contact and official death certificate searches. The cause of death was determined according to the official death certificates. We used log-rank tests to compare the probabilities of survival across subgroups. We built crude and adjusted (for age, sex and ACS subtype) Cox regression models to study if the ACS subtype or baseline characteristics were independent predictors of all-cause or cardiovascular mortality.

Results:

We identified 110 deaths in the cohort (case-fatality rate, 12.0%). Age [Hazard ratio (HR) = 2.04 per 10 year increase; 95% confidence interval (95%CI) = 1.75–2.38], non-ST elevation myocardial infarction (HR = 3.82 ; 95%CI = 2.21–6.60) or ST elevation myocardial infarction (HR = 2.59; 95%CI = 1.38–4.89) diagnoses, and diabetes (HR = 1.78; 95%CI = 1.20‑2.63) were significant risk factors for all-cause mortality in the adjusted models. We found similar results for cardiovascular mortality. A previous coronary artery disease diagnosis was also an independent predictor of all-cause mortality (HR = 1.61; 95%CI = 1.04–2.50), but not for cardiovascular mortality.

Conclusion:

We found an overall one-year mortality rate of 12.0% in a sample of post-ACS patients in a community, non-specialized hospital in São Paulo, Brazil. Age, ACS subtype, and diabetes were independent predictors of poor one‑year survival for overall and cardiovascular-related causes.

Survival and Predictive Factors of Lethality in Hemodyalisis: D/I Polymorphism of The Angiotensin I-Converting Enzyme and of the Angiotensinogen M235T Genes

Mauro Alves et al. Nelson Albuquerque de Souza e Silva Lucia Helena Alvares Salis Basilio de Bragança Pereira … Paulo Henrique Godoy Emília Matos do Nascimento Jose Mario Franco Oliveira

Background:

End-stage kidney disease patients continue to have markedly increased cardiovascular disease morbidity and mortality. Analysis of genetic factors connected with the renin-angiotensin system that influences the survival of the patients with end-stage kidney disease supports the ongoing search for improved outcomes.

Objective:

To assess survival and its association with the polymorphism of renin-angiotensin system genes: angiotensin I-converting enzyme insertion/deletion and angiotensinogen M235T in patients undergoing hemodialysis.

Methods:

Our study was designed to examine the role of renin-angiotensin system genes. It was an observational study. We analyzed 473 chronic hemodialysis patients in four dialysis units in the state of Rio de Janeiro. Survival rates were calculated by the Kaplan-Meier method and the differences between the curves were evaluated by Tarone-Ware, Peto-Prentice, and log rank tests. We also used logistic regression analysis and the multinomial model. A p value ≤ 0.05 was considered to be statistically significant. The local medical ethics committee gave their approval to this study.

Results:

The mean age of patients was 45.8 years old. The overall survival rate was 48% at 11 years. The major causes of death were cardiovascular diseases (34%) and infections (15%). Logistic regression analysis found statistical significance for the following variables: age (p = 0.000038), TT angiotensinogen (p = 0.08261), and family income greater than five times the minimum wage (p = 0.03089), the latter being a protective factor.

Conclusions:

The survival of hemodialysis patients is likely to be influenced by the TT of the angiotensinogen M235T gene.

Mortality and complications of coronary artery bypass grafting in Rio de Janeiro, from 1999 to 2003

Thaís Mendonça Lips de Oliveira et al. Gláucia Maria Moraes de Oliveira Carlos Henrique Klein Nelson Albuquerque de Souza e Silva Paulo Henrique Godoy

BACKGROUND: Coronary artery bypass grafting (CABG) is a consolidated procedure for the treatment of ischemic heart diseases (IHDs), which requires continuous assessment. OBJECTIVE: To assess the quality of CABG surgery by reviewing patients’ clinical characteristics, mortality rates up to one year after hospital discharge, primary causes of death and postoperative complications, at four public hospitals in Rio de Janeiro from 1999 to 2003. METHODS: CABG patient charts were randomly selected. A retrospective review was conducted to collect data on clinical characteristics, complications and deaths from patient medical charts and statements of death (SDs). Mortality rates were estimated for the hospitalization period and for up to one year after hospital discharge. RESULTS: The prevalence of preoperative patient characteristics were: women: 31.9%; arterial hypertension: 90.7%; dyslipidemia: 67.4%; diabetes: 37.2%; current smoking status: 22.9%; obesity: 18.3%; chronic obstructive pulmonary disease: 8.2%; prior stroke: 5.8%; extracardiac artery disease: 12.7%; elevation of creatinine levels: 4.1%; critical preoperative status: 3.7%; recent acute myocardial infarction: 23.5%; unstable angina: 40.8%; acute coronary syndrome: 50.0%; prior CABG: 2.4%; left ventricular dysfunction: 27.3%; left main coronary artery lesion: 3.9%; and associated with lesion in another system: 19.8%. In-hospital mortality rates ranged from 7.0% to 14.3%, and up to one year after hospital discharge from 8.5% to 20.2%. Ischemic heart disease (IHD) accounted for more than 80% of the deaths, and the most frequent complications after surgery were hemorrhage or post-procedural low cardiac output. Sixty percent of the patients who died had five or more complications, whereas 40% of those who survived had none. CONCLUSION: Mortality and complication rates were high. Even among those patients who survived, complications were more frequent than expected.

Increased mortality and morbidity due to acute myocardial infarction in a public hospital, in Feira de Santana, Bahia

Graça Maria Tavares de Melo Ferreira et al. Luis Cláudio Correia Helena Reis Carlos Brandão Ferreira Filho … Francisco Freitas Guilherme Melo Ferreira Ivan Júnior Nelson Oliveira Armênio Costa Guimarães

BACKGROUND: Factors related to socioeconomic status and health care quality and management may influence mortality and morbidity rates due to acute myocardial infarction (AMI). OBJECTIVE: To compare mortality and morbidity in patients with AMI hospitalized in public and private hospitals. METHODS: An observational study, with comparison groups. Clinical evaluation on admission, and recording of diagnostic, therapeutic and evolution data until discharge or death. Comparison of clinical characteristics by univariate analysis followed by bivariate analysis, evaluating the combination of predictors with death and morbidity (Killip> I), SPSS, version 13.0. RESULTS: 150 patients were evaluated, 63 (42.0%) of private hospitals and 87 (58.0%) of public hospitals, with 63.1% and 62.1% of males, aged 61.1 ± 13.8 and 60.0 ± 11.6 years, respectively. The mortality from AMI was 19.5% in public hospitals vs 4.8% in private hospitals (p = 0.001), and morbidity (Killip class> I) was 34.3% in public hospitals vs 15.0% in private hospitals (p = 0.012). There was a significant difference between public and private patients, due to lower family income and education (70.1% with one to two salaries vs 19.0%, p <0.001, and 49.4% of illiterates vs 6.3%, p 1 hour: 76.9% vs 48.6%, p = 0.003); and a longer period of time before being medicated (AMT > 15 minutes: 47.1% vs 8.0%; p <0.001); ICU for 8% of the patients in public hospitals vs 94% in private hospitals; and thrombolysis for 20.6% vs 54.0%, respectively (p <0.001). CONCLUSION: Mortality and morbidity were greater among public patients, which presented more serious conditions, arrived later at the hospital and received lower quality treatment.

Treatment of a cohort of patients with acute myocardial infarction and ST-segment elevation

Jamil da Silva Soares et al. Nelson Robson Mendes de Souza Jair Nogueira Filho Cristiane C. Cunha … Georgina Severo Ribeiro Ronald Souza Peixoto Carlos Eduardo C. Soares Leandro C. Soares Aldo Franklyn Reis Carlos Augusto Cardozo de Faria

BACKGROUND: Although thrombolysis and primary CTA are well-established procedures, they are not administered in a large proportion of the patients with STEMI who arrive to the emergency rooms. OBJECTIVE: Describe initial and final the results in a cohort of STEMI patients METHODS: The study included, from hospital admission to the discharge, 158 patients diagnosed with STEMI, from a total of 351 patients with ACS admitted to hospitals in Campos dos Goytacazes, RJ, Brazil, between 2004 and 2006. RESULTS: Of the 158 patients with STEMI, 67.7% arrived to the hospital within 180 minutes, 81.3% within 360 minutes, and 8.4% after twelve hours from the symptoms. Cinecoronariographic studies (148) were performed (93,7%). Lesions of over 70% were observed in 266 artery territories. The initial treatment was CTA in 41 (26%), thrombolytics in 50 (32%), 80% of success. Clinical treatment in 67 (42%). Approximately 35% of the patients should have undergone thrombolysis, but they didn´t. During the final treatment, 93 CTAs were performed: 89 with angiographic success (95.7%), bleeding 2 (2.2%), subacute occlusion 2 (2.2%), trunk dissection 1 (1.1%), pseudoaneurism 1 (1.1%). No deaths during angioplasty; during evolution, there were two deaths (2.1%). Twelve patients underwent myocardial revascularization surgery (MRS), while 53 underwent clinical treatment, with 11 deaths (20.7%). Global lethality was 9.5%, considering the three types of treatment. CONCLUSIONS: Patients were suitable for reperfusion, but one third of them did not have the procedure. Two deaths during evolution. The most predominant treatment was CTA, with low morbidity. Low global lethality.
