Introduction: Diabetes mellitus (DM) and chronic kidney disease (CKD) are comorbidities of great therapeutic and prognostic importance in patients with coronary artery disease (CAD). Knowledge about their prevalence, associated factors and influence on optimal medical therapy are needed to best manage this population. Methods: This is a unicentric cross-sectional analysis of 869 patients enrolled in a CAD registry in Brazil. To be included, patients needed to have a previous coronary artery revascularization procedure (either percutaneous or surgical), documented previous acute coronary syndrome, or known coronary stenosis greater than 50%. CKD was defined as creatinine clearance < 60 mL/min. DM was defined as prescription of glucose-lowering drugs or a HbA1c > 6.5%. Results: Overall, mean age was 64.7 years, 261 (30%) were women, 528 (61%) had previous myocardial infarction, and 547 (63.4%) had a previous revascularization procedure. DM was prevalent in 449 (51.7%) patients and CKD in 280 (32.2%). Both comorbidities were concomitant in 151 (17.4%) patients. On multivariate analysis, CKD was correlated to female sex (OR 2.94; 95%CI 1.88-4.67), age (OR 1.20; 95%CI 1.16-1.23), BMI (OR 0.80, 95%CI 0.76-0.84), and HDL-cholesterol (OR 0.97; 95%CI 0.96-0.99). DM was associated with age (OR 1.02, 95%CI 1.00-1.04), BMI (OR 1.05, 95%CI 1.01-1.08), high blood pressure (OR 2.1, 95%CI 1.39-3.21), and heart rate (OR 1.02, 95%CI 1.00-1.03). Concomitant presence of CKD and DM was associated with age (OR 1.09, 95%CI 1.06-1.13) and left ventricular ejection fraction (OR 0.97, 95%CI 0.95-0.98). Patients with DM were more likely to receive ACE inhibitors or ARBs (79.3% x 67.1%, p< 0.001) and calcium channel blockers (41.9% x 31.2%, p=0.001). Patients with DM and CKD had higher use of nitrates (38.4% x 25.6%, p=0.002). There was no difference in the prescription of antithrombotic drugs, beta-blockers or statins between groups. Conclusion: DM and CKD are both very prevalent comorbidities in patients with CAD. They are associated with age and risk markers such as high blood pressure and lower left ventricular ejection fraction. Although typically these populations are undertreated in others registries, this fact was not observed in our study.

Background Ad hoc percutaneous coronary intervention via radial access has become frequent in interventional cardiology services, with reduced bleeding rates, vascular complications and costs. There are few reports in the medical literature on radiological exposure rates (kerma area product − Kap, and incident air kerma − Iak) in these procedures, when they are performed via radial access. The objective of the study was to compare radiological variables in staged percutaneous coronary interventions with ad hoc interventions via radial access. [...]

Introduction: It is well established that moderate consumption of red wine is associated with reduced risk of cardiovascular (CV) events. Many observational studies have shown that this same benefit could be seen with other alcohol beverages different from wine. However, the correlation between the Brazilian sugarcane liquor (“cachaca”) and CV benefit has not been demonstrated in human trials. Hypothesis: Cachaca causes changes in biomarkers of CV risk in the same proportion as wine. Methods: In this crossover randomized study, healthy individuals were initially designated to have daily moderate alcohol consumption (MAC) of either cachaca or red wine for a period of 4 weeks. MAC, for both drinks, was denoted as a daily dose equivalent of 28g of alcohol for men and 14g for women. Then, after an abstinence period of 7 days, drink types were switched for more 4 weeks. Analysis of CV risk biomarkers were determined before and after each intervention, and consisted of C-reactive protein, lipid profile, platelet aggregability and glycid profile. (This research was funded by FAPESP 2018/09675-4). Results: Of the 37 individuals originally enrolled, 2 refused to continue the study. The average age of the individuals was 41.7 (±15.3 years) and 43.2% were men. Adherence to the protocol was considered essentially ideal, with 100% of regular use in both interventions and only 3 individuals reporting abuse during the study period. There was no significant variation in anthropometric measurements during the study, except for a weight gain (0.6kg) with red wine (p = 0.011). As seen in the table, no significant changes were noted in the inflammatory markers, lipid profile, platelet aggregability nor glycid profile before and after each intervention. Conclusions: This study shows that in healthy individuals, neither red wine nor cachaca changed CV biomarkers related to atherosclerotic progression after 4 weeks of MAC. However, there was a marked weight gain with daily wine consumption.

Recently, gut microbiota has emerged as an important mediator of several diseases such as diabetes, atherosclerosis, arterial hypertension, obesity, cancers and neuropsychiatric diseases including Alzheimer, autism and depression. Intestinal microbiota is formed by bacteria, fungi and viruses and its main function is to facilitate the absorption and metabolism of foods (protein, fat and carbohydrate). One example of the multiple actions of the gut microbiota is the bidirectional relationship between the intestine and the brain, the so-called “gut/brain axis”. Furthermore, metabolites produced by gut microbiota can induce effects locally or at distance, which suggests that the intestine is an endocrine organ. Given the participation of the gut microbiota in several diseases, there is great interest in strategies that may positively affect the gut flora and prevent or even treat diseases. Among these strategies, lifestyle change, but specially diet modulation has gained importance. In this article, we review the mechanisms through which intestinal microbiota participates in cardiovascular diseases and possible therapeutic interventions.

It was a randomized trial, and 308 patients undergoing revascularization were randomly assigned: 155 to off-pump coronary artery bypass (OPCAB) and 153 to on-pump coronary artery bypass (ONCAB). End points were freedom from death, myocardial infarction, revascularization, and cerebrovascular accidents. The rates for 10-year, event-free survival for ONCAB versus OPCAB were 69.6% and 64%, (hazard ratio [HR]: 0.88; 95% confidence interval [CI] 0.86-1.02; P = .41), respectively. Adjusted Cox proportional hazard ratio was similar (HR: 0.92; 95% CI 0.61-1.38, P = .68). A difference occurred between the duration of OPCAB and ONCAB, respectively (4.9 ± 1.5 vs 6.6 ± 1.1 h, P < .001). Statistical differences occurred between OPCAB and ONCAB in the length of intensive care unit (ICU) stay (20 ± 2.5 vs 48 ± 10 hours, P < .001), time to extubation (5.5 ± 4.2 vs 10.2 ± 3.5 hours, P < .001), hospital stay (6.7 ± 1.4 vs 9.2 ± 1.3 days, P < .001), higher incidence of atrial fibrillation (AF; 33 vs 5 patients, P < .001), and blood requirements (46 vs 64 patients, P < .001). Grafts per patient was higher in ONCAB (3.15 vs 2.55 grafts, P < .001). No difference existed between the groups in primary composite end points at 10-year follow-up. Although OPCAB surgery was related to a lower number of grafts and higher incidence of AF, it had no effects related to long-term outcomes.

Body mass index (BMI) is the most commonly used index to categorize a person as obese or non-obese, which is subject to important limitations.To evaluate the direct effect of BMI on cardiovascular outcomes among participants without central obesity.This analysis included 14,983 males and females aged 45-75 years from the Atherosclerosis Risk in Communities Study (ARIC). BMI was measured as general obesity, and waist circumference (WC), waist-to-hip ratio (WHR) and hip circumference as central obesity. Targeted maximum likelihood estimation (TMLE) was used to estimate the total effects (TEs) and the controlled direct effects (CDEs). The proportion of TE that would be eliminated if all participants were non-obese regarding central obesity was computed using the proportion eliminated (PE) index. P0.05 was considered statistically significant. Analyses were performed in the TMLE R package.The risk of cardiovascular outcomes attributed to BMI was significantly reversed by eliminating WHR obesity (p0.001). The proportion eliminated of BMI effects was more tangible for non-obese participants regarding WC (PE=127%; 95%CI (126,128)) and WHR (PE=97%; 95%CI (96,98)) for coronary heart disease (CHD), and WHR (PE=92%; 95%CI (91,94)) for stroke, respectively. With respect to sex, the proportion eliminated of BMI effects was more tangible for non-obese participants regarding WHR (PE=428%; 95%CI (408,439)) for CHD in males, and WC (PE=99%; 95%CI (89,111)) for stroke in females, respectively.These results indicate different potential effects of eliminating central obesity on the association between BMI and cardiovascular outcomes for males and females. (Arq Bras Cardiol. 2021; 116(5):879-886).O índice de massa corporal (IMC) é o índice mais usado para categorizar uma pessoa como obesa ou não-obesa, e está sujeito a limitações importantes.Avaliar o efeito direto do IMC nos desfechos cardiovasculares em participantes sem obesidade central.Esta análise incluiu 14.983 homens e mulheres com idades entre 45-75 anos do Estudo de Risco de Aterosclerose em Comunidades (ARIC). O IMC foi medido como obesidade geral e a circunferência da cintura (CC), a relação cintura-quadril (RCQ) e circunferência do quadril como obesidade central. A estimativa de máxima verossimilhança direcionada (TMLE, no acrônimo em inglês) foi usada para estimar os efeitos totais (TEs) e os efeitos diretos controlados (CDEs). A proporção de ET que seria eliminada se todos os participantes fossem não obesos em relação à obesidade central foi calculada usando o índice de proporção eliminada (PE). P0,05 foi considerado estatisticamente significativo. As análises foram realizadas no pacote TMLE R.O risco de desfechos cardiovasculares atribuídos ao IMC foi significativamente revertido com a eliminação da obesidade na RCQ (p0,001). A proporção eliminada dos efeitos do IMC foi mais tangível para participantes não obesos em relação à CC (PE = 127%; IC95% (126,128)) e RCQ (PE = 97%; IC95% (96,98)) para doença arterial coronariana (DAC), e RCQ (PE = 92%; IC95% (91,94)) para acidente vascular cerebral, respectivamente. Com relação ao sexo, a proporção eliminada dos efeitos do IMC foi mais tangível para participantes não obesos em relação a RCQ (PE = 428%; IC95% (408.439)) para DAC em homens e CC (PE = 99%; IC95% (89,111)) para acidente vascular cerebral em mulheres, respectivamente.Esses resultados indicam diferentes efeitos potenciais da eliminação da obesidade central na associação entre IMC e desfechos cardiovasculares em homens e mulheres.

Background Evidence suggests that red wine (RW) components can influence favorably gut microbiota. However, Interactions of RW, gut microbiota and plasma metabolomics remain unclear. Purpose The goal of this study was to assess the effects upon gut microbiota and plasma metabolomic profile of short-term, moderate RW intake in patients (pts) with documented coronary artery disease (CAD) Methods Forty-two males aged 60.4±5.4 years (SD) with documented CAD by angiography underwent a randomized, crossover, controlled, interventional trial. They were assigned to either RW treatment or abstinence from any alcoholic beverage, as control. Each treatment was preceded by a 2-week washout period. During the RW intervention, subjects ingested 250 ml of RW per day/ 5 days a week/ 3 weeks. Fasting blood samples and fecal samples were collected 4 times, after washout and at the end of each 3-week intervention. Gut microbiota was analysed by 16 S rRNA gene sequences and plasma metabolomics was performed by Ultrahigh Performance Liquid Chromatography-Tandem Mass Spectroscopy. Twenty pts chosen randomly had their global metabolic profiles examined at all visits. Diet was carefully controlled and quantified by a 3 day/week questionnaire at beginning and end of the study. Prebiotics, probiotics were not allowed during the study. Patients in need for antibiotic therapy were not included. Results In the RW period compared to abstinence, fecal metagenomic revealed a decrease in abundance of Collinsella, a bacterial genus correlated with atherosclerosis; an increase in Eubacterium, genus related to fiber digestion and bile acid metabolism; and a significant increase in alpha diversity (p Conclusions Moderate RW ingestion augmented microbiota diversity, increased the proportion of putative anti-atherosclerotic bacteria and influenced plasma metabolomics. RW influenced energy metabolism through gut microbiota related plasma changes in amino acids, nucleotide profile, bile acids, androgenic steroids and beta-oxidation. These findings furnish some novel insight into mechanisms whereby RW may mitigate atherosclerosis.

Importance The long-term prognostic implications of myocardial ischemia documented during stress testing in patients with multivessel coronary artery disease (CAD) are unclear. Objective To assess whether documented stress testing–induced myocardial ischemia is associated with major adverse cardiovascular events or ventricular function changes in patients with stable multivessel CAD. Design, Setting, and Participants A prospective cohort study was conducted using data from a single-center randomized clinical trial (Medicine, Angioplasty, or Surgery Study [MASS] II) to examine the association of myocardial ischemia documented during stress testing at baseline with cardiovascular events and ventricular function changes during follow-up. Participants were previously randomized (May 1, 1995, to May 31, 2000) to medical therapy, percutaneous coronary intervention with bare metal stents, or coronary artery bypass grafting. Event-free survival was estimated by the Kaplan-Meier method, and multivariable Cox regression models were calculated to assess the association between ischemia and the primary composite end point. The vital status was determined on February 28, 2011. Data were analyzed from February 1, 2016, to April 1, 2017. Main Outcomes and Measures Cardiovascular events (overall mortality, myocardial infarction, and revascularization for refractory angina) were tracked from the time of randomization to the end of the 10-year follow-up (mean [SD] duration, 11.4 [4.3] years). Myocardial ischemia was assessed at baseline and at 1-year intervals by exercise stress testing, and ventricular function (left ventricular ejection fraction) was assessed by echocardiography at baseline and after 10 years. Patients with documented ischemia were compared with those without ischemia regarding the outcomes and changes in ventricular function. Results Of 611 participants, 535 underwent exercise stress testing at baseline: 270 with documented ischemia and 265 without. Of these 535 patients, 373 (69.7%) were men, and the mean (SD) age for the entire cohort was 59.7 (9.2) years. No association was found between the presence of ischemia at baseline and survival free of combined cardiovascular events (hazard ratio, 1.00; 95% CI, 0.80-1.27;P = .95) after multivariable adjustment that included CAD initial randomized treatments. In addition, among 320 patients who underwent echocardiographic evaluation, the slight decline in left ventricular ejection fraction after 10 years was similar in both groups (median [SD] difference, −4.9% [18.7%] vs −6.6% [20.0%], respectively, for groups with and without ischemia;P = .97). Conclusions and Relevance In this study, regardless of the therapeutic strategy applied, the presence of documented myocardial ischemia did not appear to be associated with an increased occurrence of major adverse cardiovascular events or changes in ventricular function in patients with multivessel CAD during a long-term follow-up.

Background The lack of a correlation between myocardial necrosis biomarkers and electrocardiographic abnormalities after revascularization procedures has resulted in a change in the myocardial infarction (MI) definition. Methods Patients with stable multivessel disease who underwent percutaneous or surgical revascularization were included. Electrocardiograms and concentrations of high-sensitive cardiac troponin I (cTnI) and creatine kinase (CK)-MB were assessed before and after procedures. Cardiac magnetic resonance and late gadolinium enhancement were performed before and after procedures. MI was defined as more than five times the 99th percentile upper reference limit for cTnI and 10 times for CK-MB in percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG), respectively, and new late gadolinium enhancement for cardiac magnetic resonance. Results Of the 202 patients studied, 69 (34.1%) underwent on-pump CABG, 67 (33.2%) off-pump CABG, and 66 (32.7%) PCI. The receiver operating characteristic curve showed the accuracy of cTnI for on-pump CABG, off-pump CABG, and PCI patients was 21.7%, 28.3%, and 52.4% and for CK-MB was 72.5%, 81.2%, and 90.5%, respectively. The specificity of cTnI was 3.6%, 9.4%, and 42.1% and of CK-MB was 73.2%, 86.8%, and 96.4%, respectively. Sensitivity of cTnI was 100%, 100%, and 100% and of CK-MB was 69.2%, 64.3%, and 44.4%, respectively. The best cutoff of cTnI for on-pump CABG, off-pump CABG, and PCI was 6.5 ng/mL, 4.5 ng/mL, and 4.5 ng/mL (162.5, 112.5, and 112.5 times the 99th percentile upper reference limit) and of CK-MB was 37.5 ng/mL, 22.5 ng/mL, and 11.5 ng/mL (8.5, 5.1, and 2.6 times the 99th percentile upper reference limit), respectively. Conclusions Compared with cardiac magnetic resonance, CK-MB was more accurate than cTnI for diagnosing MI. These data suggest a higher troponin cutoff for the diagnosis of procedure-related MI.

Cardiovascular diseases are accountable for more than 32% of total mortality in Brazil, considered a middle-and-low-income country. Epidemiological and socio-economical issues play a crucial role on the distribution, severity and management of stable ischemic heart disease (SIHD). However

Background Chronic kidney disease (CKD) is associated with a worse prognosis in patients with stable coronary artery disease (CAD); however, there is limited randomized data on long-term outcomes of CAD therapies in these patients. We evaluated long-term outcomes of CKD patients with CAD who underwent randomized therapy with medical treatment (MT) alone, percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG). Methods Baseline estimated glomerular filtration rate (eGFR) was obtained in 611 patients randomized to one of three therapeutic strategies in the Medicine, Angioplasty, or Surgery Study II trial. Patients were categorized in preserved renal function and mild or moderate CKD groups depending on their eGFR (≥90, 89–60 and 59–30 mL/min/1.73 m2, respectively). The primary clinical endpoint, a composite of overall death and myocardial infarction, and its individual components were analyzed using proportional hazards regression (Clinical Trial registration information: http://www.controlled-trials.com. Registration number: ISRCTN66068876). Results Of 611 patients, 112 (18%) had preserved eGFR, 349 (57%) mild dysfunction and 150 (25%) moderate dysfunction. The primary endpoint occurred in 29.5, 32.4 and 44.7% (P = 0.02) for preserved eGFR, mild CKD and moderate CKD, respectively. Overall mortality incidence was 18.7, 23.8 and 39.3% for preserved eGFR, mild CKD and moderate CKD, respectively (P = 0.001). For preserved eGFR, there was no significant difference in outcomes between therapies. For mild CKD, the primary event rate was 29.4% for PCI, 29.1% for CABG and 41.1% for MT (P = 0.006) [adjusted hazard ratio (HR) = 0.26, 95% confidence interval (CI) 0.07–0.88; P = 0.03 for PCI versus MT; and adjusted HR = 0.48; 95% CI 0.31–0.76; P = 0.002 for CABG versus MT]. We also observed higher mortality rates in the MT group (28.6%) compared with PCI (24.1%) and CABG (19.0%) groups (P = 0.015) among mild CKD subjects (adjusted HR = 0.44, 95% CI 0.25–0.76; P = 0.003 for CABG versus MT; adjusted HR = 0.56, 95% CI 0.07–4.28; P = 0.58 for PCI versus MT). Results were similar with moderate CKD group but did not achieve significance. Conclusions Coronary interventional therapy, both PCI and CABG, is associated with lower rates of events compared with MT in mild CKD patients >10 years of follow-up. More study is needed to confirm these benefits in moderate CKD.

There is a strong epidemiological association between moderate consumption of alcoholic beverages, such as red wine, and other sources of polyphenols and the reduction of cardiovascular disease and mortality. Also, protective effects against atherogenic lipid profile, platelet activation, and systemic inflammation have been noted in observational studies. Glucose metabolism is also positively affected by polyphenols reducing the incidence of diabetes mellitus. Long-term consumption of moderate amounts of red wine consistently increases HDL. Polyphenols increase endothelial nitric oxide production, and decrease the endothelial abundance of endothelin-1. Resveratrol, the most abundant polyphenol of red wine, has been associated with prolongation of life span in animal experiments, and cognition preservation in humans.

Coronary artery calcification (CAC) is associated with atherosclerotic complications. However, elevated CAC may not always imply a worse prognosis. Herein, we report the clinical evolution of long-term red wine (RW) drinkers in relation to CAC. We followed 200 healthy male habitual RW drinkers and compared them to 154 abstainers for a period of 5.5 years. The initial evaluation included coronary computed tomography angiography (CTA), clinical, demographics, and laboratory data. CAC was quantified by the Agatston score. The follow-up process was conducted by telephone calls and/or hospital record review. The composite end-point of total death, acute myocardial infarction (AMI), or coronary revascularization (or major adverse cardiac event - MACE) was assessed. The RW drinkers ingested 28.9±15 g of alcohol/day for 23.4±12.3 years. They had higher high-density lipoprotein and low-density lipoprotein, but lower C-reactive protein than abstainers. Age, total cholesterol, triglycerides, glucose, and liver enzymes were similar. History of diabetes was lower among drinkers, but other risk factors were similar. However, drinkers had higher CAC than abstainers; the mean value was 131.5±362 in drinkers vs 40.5±320 in abstainers (P

Endothelial dysfunction is the link between risk factors and atherosclerosis related diseases. Thus, their evaluation discloses the impact risk factors of upon endothelial functional and it is predictive of cardiovascular outcome in persons affected by them. Endothelial function suffers prejudice proportional to total cholesterol, LDL-cholesterol, and HDL-cholesterol levels, hyperglycemia, physical inactivity, aging, blood pressure, and tobacco smoke exposition as has been observed in several clinical studies. It is also affected by family history for coronary disease and gender. An important feature is that endothelial dysfunction precedes clinical manifestations of coronary artery disease; therefore endothelial dysfunction is a marker of atherosclerosis. Importantly, endothelial dysfunction of peripheral arteries correlates with alterations in coronary circulation. We may use the endothelial function evaluation to assess prognosis the effectiveness of medication or life style modification prescribed to patients. Furthermore corrections of risk factors improves endothelial dysfunction.

Observational studies suggest there are clinical benefits to moderate red wine (RW) consumption. However, the effects on coronary vasculature and overall lifestyle are unclear. We investigated whether a lifestyle of regular long-term RW consumption is associated with changes in coronary plaque burden, calcium score, carotid intima/media thickness, endothelial function, and metabolic variables, compared with alcohol abstinence. Healthy volunteers were evaluated by coronary computed tomography angiography (CTA) as well as carotid and brachial artery ultrasound. Nutritional status, psychological status, and metabolic variables were assessed. The study included 101 drinkers [aged 58.9 ± 7.3 years (means ± SD)], from wine brotherhoods, and 104 abstainers, from Anglican, Evangelical and Catholic churches both in the city of São Paulo, Brazil. No significant differences in demographics were noted. Lesion prevalence per patient assessed by coronary CTA and classified as absent (0), 1-25, 26-49, and ≥ 50% stenosis was similar between groups. When analyzed by individual arteries, i.e., left anterior descending, circumflex, and right coronary, prevalence was also not different. On the other hand, calcium scores were higher among drinkers than abstainers (144.4 ± 362.2 vs 122.0 ± 370.3; P0.01). However, drinkers reported less history of diabetes and exercised more. RW drinkers consumed 2127.9 ± 387.7 kcal/day while abstainers consumed 1836.0 ± 305.0 (P0.0001). HDL cholesterol was significantly higher among drinkers compared to abstainers (46.9 ± 10.9 vs 39.5 ± 9.0 mg/dL; P0.001), while fasting plasma glucose was lower (97.6 ± 18.2 vs 118.4 ± 29.6 mg/dL; P0.02). Liver enzymes were normal in both groups. In conclusion, long-term wine drinkers displayed a similar plaque burden but greater calcium score than abstainers, despite a more atherogenic diet, and the mechanisms for the increased calcium scores in the former remain speculative.

The long-term prognostic impact of glycated hemoglobin (HbA1c) values in patients with type 2 diabetes mellitus (DM) and multivessel coronary artery disease (CAD) has been tested, but the effect of variability in HbA1c is unclear. In a Brazilian cohort of CAD patients with type 2 DM, measures of

Introduction Diabetes mellitus is a major cause of coronary artery disease (CAD). Despite improvement in the management of patients with stable CAD, diabetes remains a major cause of increased morbidity and mortality. There is no conclusive evidence that either modality is better than medical therapy alone for the treatment of stable multivessel CAD in patients with diabetes in a very long-term follow-up. Our aim was to compare 3 therapeutic strategies for stable multivessel CAD in a diabetic population and non-diabetic population. Methods It was compared medical therapy (MT), percutaneous coronary intervention (PCI), and coronary artery bypass graft (CABG) in 232 diabetic patients and 379 nondiabetic patients with multivessel CAD. Endpoints evaluated were overall and cardiac mortality. Results Patients (n = 611) were randomized to CABG (n = 203), PCI (n = 205), or MT (n = 203). In a 10-year follow-up, more deaths occurred among patients with diabetes than among patients without diabetes ( P = .001) for overall mortality. In this follow-up, 10-year mortality rates were 32.3% and 23.2% for diabetics and non-diabetics respectively ( P = .024). Regarding cardiac mortality, 10-year cardiac mortality rates were 19.4% and 12.7% respectively ( P = .031).Considering only diabetic patients and stratifying this population by treatment option, we found mortality rates of 31.3% for PCI, 27.5% for CABG and 37.5% for MT ( P = .015 for CABG vs MT) and cardiac mortality rates of 18.8%, 12.5% and 26.1% respectively ( P = .005 for CABG vs MT). Conclusions/interpretation Among patients with stable multivessel CAD and preserved left ventricular ejection fraction, the 3 therapeutic regimens had high rates of overall and cardiac-related deaths among diabetic compared with non-diabetic patients. Moreover, better outcomes were observed in diabetic patients undergoing CABG compared to MT in relation to overall and cardiac mortality in a 10-year follow-up.

Background: Studies have questioned the downward trend in mortality from cardiovascular diseases (CVD) in Brazil in recent years. Objective: to analyze recent trends in mortality from ischemic heart disease (IHD) and stroke in the Brazilian population. Methods: Mortality and population data were obtained from the Brazilian Institute of Geography and Statistics and the Ministry of Health. Risk of death was adjusted by the direct method, using as reference the world population of 2000. We analyzed trends in mortality from CVD, IHD and stroke in women and men in the periods of 1980-2006 and 2007-2012. Results: there was a decrease in CVD mortality and stroke in women and men for both periods (p < 0.001). Annual mortality variations for periods 1980-2006 and 2007-2012 were, respectively: CVD (total): -1.5% and -0.8%; CVD men: -1.4% and -0.6%; CVD women: -1.7% and -1.0%; DIC (men): -1.1% and 0.1%; stroke (men): -1.7% and -1.4%; DIC (women): -1.5% and 0.4%; stroke (women): -2.0% and -1.9%. From 1980 to 2006, there was a decrease in IHD mortality in men and women (p < 0.001), but from 2007 to 2012, changes in IHD mortality were not significant in men [y = 151 + 0.04 (R2 = 0.02; p = 0.779)] and women [y = 88-0.54 (R2 = 0.24; p = 0.320). Conclusion: Trend in mortality from IHD stopped falling in Brazil from 2007 to 2012. Resumo Fundamento: Estudos questionaram a tendência de queda da mortalidade por doenças cardiovasculares (DCV) no Brasil nos últimos anos. Objetivo: analisar as tendências recentes na mortalidade por doença isquêmica do coração (DIC) e doenças cerebrovasculares (DCbV) na população brasileira. Métodos: dados de mortalidade e população foram obtidos do Instituto Brasileiro de Geografia e Estatística e Ministério da Saúde. O risco de morte foi ajustado pelo método direto, tendo como referência a população mundial de 2000. Foram analisadas, nos períodos de 1980-2006 e 2007-2012, as tendências da mortalidade em mulheres e homens. Resultados: houve diminuição da mortalidade por DCV e DCbV em mulheres e homens para ambos os períodos (p < 0,001). As variações anuais de mortalidade para os períodos de 1980-2006 e 2007-2012 foram, respectivamente: DCV total: -1,5% e -0,8%; DCV homens: -1,4% e -0,6%; DCV mulheres: -1,7% e -1,0%; DIC homens: -1,1% e 0,1%; DIC mulheres: -1,5% e 0,4%; DCbV homens: -1,7% e -1,4%; DCbV mulheres: -2,0% e -1,9%. De 1980 a 2006, houve diminuição da mortalidade por DIC em homens e mulheres (p < 0,001), mas de 2007-2012, as mudanças na mortalidade por DIC não foram significativas em homens [y = 151 + 0.04 (R2 = 0.02; p = 0,779)] e mulheres [y = 88-0.54 (R2 = 0,24; p = 0,320)]. Conclusão: A tendência da mortalidade por DIC parou de cair no Brasil de 2007 a 2012.

The primary end points of randomized clinical trials evaluating the outcome of therapeutic strategies for coronary artery disease (CAD) have included nonfatal acute myocardial infarction, the need for further revascularization, and overall mortality. Noncardiac causes of death may distort the interpretation of the long-term effects of coronary revascularization.This post-hoc analysis of the second Medicine, Angioplasty, or Surgery Study evaluates the cause of mortality of patients with multivessel CAD undergoing medical treatment, percutaneous coronary intervention, or surgical myocardial revascularization [coronary artery bypass graft surgery (CABG)] after a 6-year follow-up. Mortality was classified as cardiac and noncardiac death, and the causes of noncardiac death were reported.Patients were randomized into CABG and non-CABG groups (percutaneous coronary intervention plus medical treatment). No statistical differences were observed in overall mortality (P=0.824). A significant difference in the distribution of causes of mortality was observed among the CABG and non-CABG groups (P=0.003). In the CABG group, of the 203 randomized patients, the overall number of deaths was 34. Sixteen patients (47.1%) died of cardiac causes and 18 patients (52.9%) died of noncardiac causes. Of these, seven deaths (20.6%) were due to neoplasia. In the non-CABG group, comprising 408 patients, the overall number of deaths was 69. Fifty-three patients (77%) died of cardiac causes and 16 patients (23%) died of noncardiac causes. Only five deaths (7.2%) were due to neoplasia.Different treatment options for multivessel coronary artery disease have similar overall mortality: CABG patients had the lowest incidence of cardiac death, but the highest incidence of noncardiac causes of death, and specifically a higher tendency toward cancer-related deaths.
