ABSTRACT

OBJECTIVES: The influence of the bleeding site on long-term survival after the primary percutaneous coronary intervention (PCI) is poorly understood. This study sought to investigate the relationship between in-hospital access site versus non-access site bleeding and very late mortality in unselected patients treated with primary PCI. METHODS: Data of the 2715 consecutive patients with ST-segment elevation myocardial infarction treated with primary PCI, enrolled in a prospective registry of a high volume tertiary centre, were analysed. Bleeding events were assessed according to the Bleeding Academic Research Consortium (BARC) criteria. The primary outcome was 4-year mortality. RESULTS: The BARC type ≥2 bleeding occurred in 171 patients (6.3%). Access site bleeding occurred in 3.8%, and non-access site bleeding in 2.5% of patients. Four-year mortality was significantly higher for patients with bleeding (BARC type ≥2) than in patients without bleeding (BARC type 0+1), (36.3% vs 16.2%, p<0.001). Patients with non-access site bleeding had higher 4 year mortality (50.7% vs 26.5%, p=0.001). After multivariable adjustment, BARC type ≥2 bleeding was the independent predictor of 4 year mortality (HR 2.01; 95% CI 1.49 to 2.71, p<0.001). Patients with a non-access site bleeding were at 2-fold higher risk of very late mortality than patients with an access site bleeding (HR 2.62; 1.78 to 3.86, p<0.001 vs HR 1.57; 1.03 to 2.38, p=0.034). CONCLUSIONS: Both access and non-access site BARC type ≥2 bleeding is independently associated with a high risk of 4-year mortality after primary PCI. Patients with non-access site bleeding were at higher risk of late mortality than patients with access site bleeding.

ABSTRACT

BACKGROUND/AIM: Data about bleeding complicating primary percutaneous coronary intervention (PCI) are more frequently obtained from randomized clinical trials on patients with acute coronary syndromes (ACS), but less frequently from surveys or registries on patients with ST-elevation myocardial infarction (STEMI). The aim of this study was to investigate the incidence, predictors and prognostic impact of in-hospital major bleeding in the population of unselected real-world patients with acute STEMI undergoing primary PCI. METHODS: All consecutive patients presenting with STEMI who underwent primary PCI at a single large tertiary healthcare center between January 2005 and July 2009, were studied. Major bleeding was defined according to the Global Use of Strategies to Open Occluded Coronary Arteries (GUSTO) study criteria. We examined the association between in-hospital major bleeding and death or major adverse cardiac events (MACE) in patients treated with PCI. The primary outcomes were in-hospital and 6-month mortality and MACE. RESULTS: Of the 770 STEMI patients treated with primary PCI, in-hospital major bleeding occurred in 32 (4.2%) patients. Independent pre-dictors of major bleeding were advanced age (≥ 65 years), female gender, baseline anemia and elevated white blood cell (WBC) count and signs of congestive heart failure at admission (Killip class II-IV). In-hospital and 6 month mortality and MACE, rates were more than 2.5-fold-higher in patients who developed major bleeding compared with those who did not. Major bleeding was predictor of 6-month MACE, independent of a few risk factors (previous MI, previous PCI, diabetes mellitus and hypertension); (OR = 3.02; 95% CI for OR 1.20-7.61; p = 0.019) but was not a true independent predictor of MACE and mortality in the fully adjusted models. CONCLUSION: Patients of advanced age, female gender, with baseline anemia and elevated WBC count and those with Killip class II-IV at presentation are at particularly high risk of bleeding after primary PCI. Bleeding is associated with adverse outcome and may be an important marker of patient frailty, but it is not a true independent predictor of mortality/MACE.

ABSTRACT

OBJECTIVE: To investigate the relationship between inhospital bleeding as defined by Bleeding Academic Research Consortium (BARC) consensus classification and short-term and long-term mortality in unselected patients admitted for primary percutaneous coronary intervention (PCI). METHODS: We analysed data of all consecutive patients with ST segment elevation myocardial infarction (STEMI) admitted for primary PCI, enrolled in a prospective registry of a high volume centre. The BARC-defined bleeding events were reconstructed from the detailed, prospectively collected clinical data. The primary outcome was mortality at 1 year. RESULTS: Of the 1808 patients with STEMI admitted for primary PCI, 115 (6.4%) experienced a BARC type ≥2 bleeding. As the BARC bleeding severity worsened, there was a gradient of increasing rates of 1-year death. The 1-year mortality rate increased from 11.5% with BARC 0+1 type to 43.5% with BARC type 3b bleeding. After multivariable adjustment for demographic and clinical characteristics of patients, the independent predictors of 1-year death were BARC type 3a (HR 1.99; 95% CI 1.16 to 3.40, p=0.012) and BARC type 3b bleeding (HR 3.22; 95% CI 1.67 to 6.20, p<0.0001). CONCLUSIONS: The present study demonstrated that bleeding events defined according to the BARC classification hierarchically correlate with 1-year mortality after admission for primary PCI. The strongest predictor of 1-year mortality is the BARC type 3b bleeding.

ABSTRACT

BACKGROUND: The aim of this study was to evaluate some hypotheses about factors related to the development of type 1 diabetes mellitus. METHODS: A case-control study was conducted in Belgrade during the period 1994-1997. A total of 105 recently onset diabetic and 210 control children, individually matched by age (+/-1 year), sex and place of residence, were included in the study. RESULTS: According to multivariate regression analysis, the following factors were related to type 1 diabetes: stressful events and symptoms of psychological dysfunction during the 12 months preceding the onset of the disease [odds ratio (OR) 3.48, 95% confidence interval (CI) 2.15-5.65; and OR 2.15, 95% CI 1.33-3.48], irregular vaccination (OR 16.98, 95% CI 1.38-208.92), infection during 6 months preceding the onset of the disease (OR 4.23, 95% CI 1.95-9.17), higher education of father (OR 1.50, 95% CI 1.05-2.14), mother's consumption of nitrosoamines-rich food during pregnancy (OR 4.33, 95% CI 1.95-9.61), alcohol consumption by father (OR 3.80, 95% CI 1.64-8.78), insulin-dependent and non-insulin-dependent diabetes mellitus in three generations of children's relatives (OR 20.04, 95% CI 4.73-84.81; and OR 5.52, 95% CI 2.45-12.46), and use of ultrasound diagnostic techniques during pregnancy (OR 0.42, 95% CI 0.17-1.00). CONCLUSIONS: Among non-genetic factors, those affecting the child during pregnancy are especially important because of their preventability.
