A idade influencia os desfechos em pacientes com idade igual ou superior a 70 anos submetidos à cirurgia de revascularização miocárdica isoladaAge influences outcomes in 70-year or older patients undergoing isolated coronary artery bypass graft surgery Abstract Objective: To analyze the results of isolated on-pump coronary artery bypass graft surgery (CABG) in patients ≥ 70 years old in comparison to patients <70 years old.Methods: Patients undergoing isolated CABG were selected for the study. The patients were assigned into two groups: G1 (age ≥ 70 years old) and G2 (age <70 years old).The endpoints were in-hospital mortality, acute myocardial infarction (AMI), stroke, re-exploration for bleeding, intraaortic balloon pump for circulatory shock, respiratory complications, acute renal failure, mediastinitis, sepsis, atrial fibrillation, and complete atrioventricular block (CAVB).Results: A total of 1,033 were included in the study: G1 Rev Bras Cir Cardiovasc 2012;27(1):45-51

Extensive waiting periods for CABG contribute to higher mortality and morbidity rates, especially in patients with left ventricular dysfunction.

Increased C-reactive protein (CRP) is a predictor of cardiovascular risk, but its influence on outcomes after coronary artery bypass grafting surgery (CABG) is still incompletely studied. We studied the association between preoperative CRP and inhospital death after CABG. Patients with acute or chronic infectious or inflammatory disorders, autoimmune diseases, cancer, and prior cardiac surgery were excluded. Seventy-six patients were studied [27.6% with elevated CRP (>3 mg/l)]. Elevated CRP was more frequently found in patients who died than in those who survived (83.3% vs 17.1%, p = 0.003); mean CRP levels were, respectively, 6.5 ± 3.4 vs 2.4 ± 3.5 mg/l (p = 0.03). The hazard ratio of death was 11.7 for elevated CRP, and the ROC curve for the discrimination of death with CRP had an area under the curve of 0.82. An improvement to mortality risk prediction following CABG may be offered by the preoperative analysis of CRP.

or = 50%) consecutively identified on diagnostic cardiac catheterization during an 8-month period were selected for the study. The group comprised 56 patients (40 males and 16 females) with a mean age of 61±10 years. The cardiac events included death, nonfatal acute myocardial infarction, acute left ventricular failure, unstable angina, and emergency surgery. RESULTS: While waiting for surgery, patients experienced the following cardiac events: 7 acute myocardial infarctions and 1 death. All events occurred within the first 60 days after the diagnostic cardiac catheterization. More patients, whose indication for diagnostic cardiac catheterization was unstable angina, experienced events as compared with those with other indications [p=0.03, relative risk (RR) = 5.25, 95% confidence interval = 1.47 - 18.7]. In the multivariate analysis of logistic regression, unstable angina was also the only factor that independently contributed to a greater number of events (p = 0.02, OR = 8.43, 95% CI =1.37 - 51.7). CONCLUSION: Unstable angina in patients with left main coronary artery disease acts as a high risk factor for cardiac events, emergency surgery being recommended in these cases.]]>

At the non-ICU, deaths occur more often in the morning period and follow a circadian rhythm, which does not occur at the ICU.

Background: The monitoring of healthcare quality indicators (HCQI) is a process of utmost importance in patient healthcare services.

Patients with 50% or more LMCAD and LV dysfunction had increased survival with CABG. However, outcomes of patients with 50% or more LMCAD and normal LV function were not significantly different with either MT or CABG.
