article 3 Citação(ões) na Scopus New Prognostic Score for Stable Coronary Disease Evaluation(2011) STORTI, Fernanda Coutinho; MOFFA, Paulo Jorge; UCHIDA, Augusto H.; HUEB, Whady Armindo; CESAR, Luiz Antonio Machado; FERREIRA, Beatriz Moreira Ayub; CAMARGO JR., Paulo Augusto de; CHALELA, William AzemBackground: The need to improve the exercise testing accuracy, pushed the development of scores, whose applicability was already broadly recognized. Objective: Prognostic evaluation of stable coronary disease through a new simplified score. Methods: A new score was applied in 372 multivessel coronary patients with preserved ventricular function, 71.8% male, age: 59.5 (+/- 9.07) years old, randomized to medical treatment, surgery (CABG) or angioplasty (PTCA), with 5 years of follow-up. Cardiovascular death was considered the primary endpoint. Non-fatal myocardial infarction, death and re-intervention were considered for a combined secondary endpoint. The score was based on an equation previously validated, resulting from a sum of one point for: male gender, infarction history, angina, diabetes, insulin use and one point for each decade of life after 40 years old. Positive exercise testing summed one additional point. Results: Thirty six deaths was observed (10 in group PTCA, 15 in CABG and 11 in the clinical group), p = 0.61. We observed 93 combined events: 37 in PTCA group, 23 in CABG and 33 in the clinical group (p = 0.058). 247 patients presented clinical score >= 5 points and 216 >= 6 points. The cutoff point >= 5 or >= 6 points identified higher risk, p = 0.015 and p = 0.012, respectively. The survival curve showed a different death incidence after the randomization when score reached 06 points or more (p = 0.07), and a distinct incidence of combined events between the patients with score < 6 and >= 6 points (p = 0.02). Conclusion: The new score was consistent for multiarterial stable coronary disease risk stratification. (Arq Bras Cardiol 2011;96(5):411-419)- Effects of Optimal Medical Treatment With or Without Coronary Revascularization on Angina and Subsequent Revascularizations in Patients With Type 2 Diabetes Mellitus and Stable Ischemic Heart Disease(2011) DAGENAIS, Gilles R.; LU, Jiang; FAXON, David P.; KENT, Kenneth; LAGO, Rodrigo M.; LEZAMA, Carlos; HUEB, Whady; WEISS, Melvin; SLATER, James; FRYE, Robert L.Background-In the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial, an initial strategy of coronary revascularization and optimal medical treatment (REV) compared with an initial optimal medical treatment with the option of subsequent revascularization (MED) did not reduce all-cause mortality or the composite of cardiovascular death, myocardial infarction, and stroke in patients with type 2 diabetes mellitus and stable ischemic heart disease. In the same population, we tested whether the REV strategy was superior to the MED strategy in preventing worsening and new angina and subsequent coronary revascularizations. Methods and Results-Among the 2364 men and women (mean age, 62.4 years) with type 2 diabetes mellitus, documented coronary artery disease, and myocardial ischemia, 1191 were randomized to the MED and 1173 to the REV strategy preselected in the percutaneous coronary intervention (796) and coronary artery bypass graft (377) strata. Compared with the MED strategy, the REV strategy at the 3-year follow-up had a lower rate of worsening angina (8% versus 13%; P < 0.001), new angina (37% versus 51%; P = 0.001), and subsequent coronary revascularizations (18% versus 33%; P < 0.001) and a higher rate of angina-free status (66% versus 58%; P = 0.003). The coronary artery bypass graft stratum patients were at higher risk than those in the percutaneous coronary intervention stratum, and had the greatest benefits from REV. Conclusions-In these patients, the REV strategy reduced the occurrence of worsening angina, new angina, and subsequent coronary revascularizations more than the MED strategy. The symptomatic benefits were observed particularly for high-risk patients.
- Preoperative B-type natriuretic peptide, and not the inflammation status, predicts an adverse outcome for patients undergoing heart surgery(2011) GANEM, Fernando; SERRANO JR., Carlos V.; FERNANDES, Juliano L.; BLOTTA, Maria Heloisa S. L.; SOUZA, Juliana A.; NICOLAU, Jose C.; RAMIRES, Jose A. F.; HUEB, Whady A.Objectives: B-type natriuretic peptide (BNP) and inflammatory markers are implicated in the pathophysiology of both ischemic cardiomyopathy and complications after cardiac surgery with cardiopulmonary bypass (CPB). The purpose of this study was to assess preoperative and postoperative levels of BNP, interleukin-6 (IL-6), interleukin-8 (IL-8), P-selectin, intercellular adhesion molecule (ICAM), C-reactive protein (CRP) in patients undergoing cardiac surgery with CPB and investigate their variation and ability to correlate with immediate outcome. Methods: Plasma levels of these markers were measured preoperatively, 6 and 24 h after CBP in 62 patients. Main endpoints were requirements for intra-aortic balloon pump, intensive care unit (ICU) stay longer than five days, ventilator dependence >24 h, requirement for dobutamine, hospital stay >10 days, clinical complications (infection, myocardial infarction, renal failure, stroke and ventricular arrhythmias) and in-hospital mortality. Results: Preoperative BNP levels correlate with longer ICU stay (P=0.003), longer ventilator use (P=0.018) and duration of dobutamine use (P<0.001). The receiver-operating characteristic curve demonstrated BNP levels >190 pg/ml as predictor of ICU >5 days and BNP levels >20.5 pg/ml correlated with dobutamine use, with areas under the curve of 0.712 and 0.842, respectively. Preoperative levels of ICAM-1 were associated with in-hospital mortality (P=0.042). In the postoperative period, was found association between CRP, IL-6 and P-selectin with ventilation duration (P=0.013, P=0.006, P<0.001, respectively) and P-selectin with ICU stay (P=0.009). Conclusions: BNP correlates with clinical endpoints more than inflammatory markers and can be used as a predictor of early outcome after heart surgery.
- Genetic Variants of Diabetes Risk and Incident Cardiovascular Events in Chronic Coronary Artery Disease(2011) SOUSA, Andre Gustavo P.; LOPES, Neuza H.; HUEB, Whady A.; KRIEGER, Jose Eduardo; PEREIRA, Alexandre C.Objective: To determine whether information from genetic risk variants for diabetes is associated with cardiovascular events incidence. Methods: From the about 30 known genes associated with diabetes, we genotyped single-nucleotide polymorphisms at the 10 loci most associated with type-2 diabetes in 425 subjects from the MASS-II Study, a randomized study in patients with multi-vessel coronary artery disease. The combined genetic information was evaluated by number of risk alleles for diabetes. Performance of genetic models relative to major cardiovascular events incidence was analyzed through Kaplan-Meier curve comparison and Cox Hazard Models and the discriminatory ability of models was assessed for cardiovascular events by calculating the area under the ROC curve. Results: Genetic information was able to predict 5-year incidence of major cardiovascular events and overall-mortality in non-diabetic individuals, even after adjustment for potential confounders including fasting glycemia. Non-diabetic individuals with high genetic risk had a similar incidence of events then diabetic individuals (cumulative hazard of 33.0 versus 35.1% of diabetic subjects). The addition of combined genetic information to clinical predictors significantly improved the AUC for cardiovascular events incidence (AUC = 0.641 versus 0.610). Conclusions: Combined information of genetic variants for diabetes risk is associated to major cardiovascular events incidence, including overall mortality, in non-diabetic individuals with coronary artery disease.
- The effect of internal thoracic artery grafts on long-term clinical outcomes after coronary bypass surgery(2011) HLATKY, Mark A.; SHILANE, David; BOOTHROYD, Derek B.; BOERSMA, Eric; BROOKS, Maria M.; CARRIE, Didier; CLAYTON, Tim C.; DANCHIN, Nicolas; FLATHER, Marcus; HAMM, Christian W.; HUEB, Whady A.; KAHLER, Jan; LOPES, Neuza; POCOCK, Stuart J.; RODRIGUEZ, Alfredo; SERRUYS, Patrick; SIGWART, Ulrich; STABLES, Rodney H.Objectives: We sought to compare long-term outcomes after coronary bypass surgery with and without an internal thoracic artery graft. Methods: We analyzed clinical outcomes over a median follow-up of 6.7 years among 3,087 patients who received coronary bypass surgery as participants in one of 8 clinical trials comparing surgical intervention with angioplasty. We used 2 statistical methods (covariate adjustment and propensity score matching) to adjust for the nonrandomized selection of internal thoracic artery grafts. Results: Internal thoracic artery grafting was associated with lower mortality, with hazard ratios of 0.77 (confidence interval, 0.62-0.97; P = .02) for covariate adjustment and 0.77 (confidence interval, 0.57-1.05; P = .10) for propensity score matching. The composite end point of death or myocardial infarction was reduced to a similar extent, with hazard ratios of 0.83 (confidence interval, 0.69-1.00; P = .05) for covariate adjustment to 0.78 (confidence interval, 0.61-1.00; P = .05) for propensity score matching. There was a trend toward less angina at 1 year, with odds ratios of 0.81 (confidence interval, 0.61-1.09; P = .16) in the covariate-adjusted model and 0.81 (confidence interval, 0.55-1.19; P = .28) in the propensity score-adjusted model. Conclusions: Use of an internal thoracic artery graft during coronary bypass surgery seems to improve long-term clinical outcomes. (J Thorac Cardiovasc Surg 2011; 142: 829-35)
