Complete Revascularization and Survival in STEMI.

Background: Complete revascularization (CR) of ST-elevation myocardial infarction patients with multivessel coronary artery disease (MVD) has proven better regarding combined endpoints than incomplete revascularization (IR) in recent randomized control trials with no impact on survival. Objective: To retrospectively evaluate the impact of complete CR during the index hospitalization on survival in STEMI patients with MVD. Methods and results: We included all patients with MVD who underwent successful primary percutaneous coronary intervention for STEMI during their index hospitalization at the University Medical Centre Ljubljana, Slovenia (from 1 January 2009 to 3 April 2011). Coronary angiograms were reviewed for non-culprit coronary arteries (>2 mm in diameter and ≥50% stenosis) treated with percutaneous coronary intervention. Rates of all-cause and cardiovascular death were compared between 235 patients who underwent CR (N = 70) or IR (N = 165). After a median follow-up of 7.0 years (interquartile range 6.0-8.2) the CR group had lower rates of all-cause death (15.7% vs 35.8%, log-rank p = 0.003) and cardiovascular death (12.9% vs 23.6%, log-rank p = 0.046). Multivariable analysis with adjustment for confounders showed no benefit of CR for all-cause death (hazard ratio [HR] 0.60, 95% confidence interval [CI] 0.31-1.18, p = 0.139) or cardiovascular death (HR 0.80, 95% CI 0.37-1.72, p = 0.560). Age, elevated serum creatinine at inclusion, diabetes and cardiogenic shock at presentation were predictors of death. Conclusions: Patients with STEMI and MVD who underwent CR showed lower all-cause and cardiovascular death during follow-up than those who underwent IR. However, after adjustment for confounders, the real determinates of survival were independent of the revascularization method.

Laparoscopically assisted colorectal surgery provides better short-term clinical and inflammatory outcomes compared to open colorectal surgery.

INTRODUCTION: Changes in immune function after surgery may influence overall outcome, length of hospital stay, susceptibility to infection and perioperative tumour dissemination in cancer patients. Our aim was to elaborate on postoperative differences in the immune status and the intensity of the systemic inflammatory response between two groups of prospectively enrolled patients with colorectal cancer, namely patients undergoing laparoscopically assisted or open colorectal surgery. MATERIAL AND METHODS: Blood samples from 77 patients were taken before surgery and then 3 h, 24 h and 4 days after surgery. The inflammatory response was determined by leukocyte counts, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and procalcitonin levels (PCT). Immune status was determined by phenotypic analysis of lymphocyte populations and the activation of mononuclear cells. CD64 expression and cytokine expression were also determined. RESULTS: Patients undergoing laparoscopically assisted surgery had less intraoperative blood loss (p = 0.002), earlier resumption of diet (p = 0.002) and shorter hospital stay (p = 0.02). Numbers of total leukocytes (p = 0.12), CRP (p = 0.002) and PCT (p = 0.23) were remarkably higher 4 days after surgery in patients who underwent an open colorectal procedure. There was an important decrease in monocyte HLA-DR expression 3 h after surgery in patients undergoing laparoscopically assisted surgery (p = 0.03). CONCLUSIONS: Our study suggests that minimally invasive surgery provides better short-term clinical outcomes for patients with resectable colorectal cancer. The acute inflammatory response is less pronounced. Post-surgical immunological disturbance in both groups is similar, but we observed a divergent effect of different surgical approaches on the expression of HLA-DR on monocytes. However, our results corroborate the results of previous studies.
