RESUMEN
Background: Patients with ST-segment elevation myocardial infarction (STEMI) and COVID-19 infection have a worse clinical course and prognosis. The prognostic significance of the timing of STEMI in relation to COVID-19 infection was not investigated. Objectives: To assess whether the time of STEMI development in relation to COVID-19 infection (concurrent or following the infection) influenced the short-term prognosis. Methods: This was an observational study of consecutive COVID-19 patients with STEMI admitted to the COVID-hospital Batajnica (February 2021-March 2022). The patients were divided into the "STEMI first" group: patients with STEMI and a positive polymerase chain reaction test for COVID-19, and the "COVID-19 first" group: patients who developed STEMI during COVID-19 treatment. All patients underwent coronary angiography. The primary endpoint was in-hospital all-cause mortality. Results: The study included 87 patients with STEMI and COVID-19 (Mage, 66.7 years, 66% male). The "STEMI first" group comprised 54 (62.1%) patients, and the "COVID-19 first" group included 33 (37.9%) patients. Both groups shared a comparatively high burden of comorbidities, similar angiographic and procedural characteristics, and high percentages of performed percutaneous coronary interventions with stent implantation (90.7% vs. 87.9%). In-hospital mortality was significantly higher in the "COVID-19 first" group compared to the "STEMI first" group (51.5% vs. 27.8%). Following adjustment, the "COVID-19 first" group had a hazard ratio of 3.22 (95% confidence interval, 1.18-8.75, p = .022) for in-hospital all-cause death, compared with the "STEMI first" group (reference). Conclusion: Clinical presentation with COVID-19 infection, followed by STEMI ("COVID-19 first"), was associated with greater short-term mortality compared to patients presenting with STEMI and testing positive for COVID-19 ("STEMI first").

Background/Aim: Despite technological advances in diagnosis and treatment, in-hospital mortality with acute aortic dissection type B is still about 11%. The purpose of this study was to assess the risk factors for early and long-term adverse outcomes in patients with acute aortic dissection type B treated medically or with conventional open surgery. Methods: The present study included 104 consecutive patients with acute aortic dissection type B treated in our Center from January 1st, 1998 to January 1st, 2007. Patient demographic and clinical characteristics as well as in-hospital complications were reviewed. Univariate and multivariate testing was performed to identify the predictors of in-hospital (30-day) and late (within 9 years) mortality. Results: 92 (88.5%) patients were treated medically, while 12 (11.5%) patients with complicated acute aortic dissection type B were treated by open surgical repair. In-hospital complications occurred in 35.7% patients, the most often being acute renal failure (28%), hypotension/shock (24%), mesenteric ischemia (12%), and limb ischemia (8%). The in-hospital mortality rate was 15.7% and the 9-year mortality rate was 51.9%. Independent predictors of early mortality in patients with acute aortic dissection type B were uncontrolled hypertension (HR-20.69) and a dissecting aorta diameter >4.75 cm (HR-6.30). Independent predictors of late mortality were relapsing pain (HR-7.93), uncontrolled hypertension (HR-7.25), and a pathologic difference in arterial blood pressure (>20 mmHg) (HR-5.33). Conclusion: Knowledge of key risk factors may help with a better choice of treatment and mortality reduction in acute aortic dissection type B patients.
RESUMEN
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.

BACKGROUND: Rapid clinical decision-making on further management of patients with out-of-hospital cardiac arrest may be challenging. Recently, a "futility" score (NULL-PLEASE) incorporating multiple adverse resuscitation features (Nonshockable rhythm, Unwitnessed arrest, Long no-flow or Long low-flow period, blood PH <7.2, Lactate >7.0 mmol/L, End-stage chronic kidney disease on dialysis, Age ≥85 years, Still resuscitation, and Extracardiac cause) has been proposed to help identify patients with out-of-hospital cardiac arrest unlikely to survive; however, external independent score validation is lacking. METHODS: We retrospectively validated the NULL-PLEASE predictive ability for early in-hospital outcome of out-of-hospital cardiac arrest in a single-center cohort of 547 consecutive patients with out-of-hospital cardiac arrest who were admitted from April 2013 to October 2016 (mean age, 66.3 ± 13.2 years); 227 patients (41.5%) died. Because pH and lactate were inconsistently measured, a modified NULL-PLEASE score excluding both variables was calculated as the principal analysis. A sensitivity analysis included the subgroup with pH data available (n = 177). RESULTS: Long low-flow period and age ≥85 years were independently associated with fatal outcome (both P < .001). Patients with a modified NULL-PLEASE score of ≥5 had a 3.3-fold greater risk of fatal outcome compared with a score of 0 to 4 (odds ratio, 3.34; 95% confidence interval [CI], 2.29-4.89; P < .001); 77% of nonsurvivors had a score ≥5; NULL-PLEASE showed a modest predictive ability for fatal outcome (c-statistic 0.658; 95% CI, 0.613-0.704; P < .001). Sensitivity analysis yielded similar results, with 88% of nonsurvivors having a score ≥5. CONCLUSIONS: The NULL-PLEASE score was predictive for early in-hospital outcome of out-of-hospital cardiac arrest, with a 3.3-fold greater odds for fatal outcome at the score values of ≥5.

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.

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.

BACKGROUND: The long-term risk of stroke after acute myocardial infarction (AMI) complicated with new-onset atrial fibrillation (AF) remains unclear. The aim of this study was to determine the long-term risk of AF and stroke in patients with AMI complicated with new-onset AF. METHODS: Patients with AMI complicated with new-onset AF (n = 260) and those without new-onset AF (n = 292) were followed for a mean of 7 years. All patients had sinus rhythm at hospital discharge. RESULTS: During the follow-up, AMI patients with new-onset AF had more frequent AF than those without new-onset AF (10.4% vs 2.7%, respectively; P < 0.0001). New-onset AF during AMI was a significant predictor of subsequent AF occurrence (the time elapsing between 2 consecutive R waves [RR] = 3.15, P = 0.004); but AF recurrence in follow-up (RR = 5.08, P = 0.001) and non-anticoagulation at discharge (RR = 0.29, P = 0.008) were independent predictors of stroke (Cox regression analysis). A period of 3.5 hours of AF within the first 48 hours of AMI was the high sensitivity cut-off level for the prediction of low long-term risk of stroke obtained by receiver operating characteristic analysis. Among patients who did not receive anticoagulants at discharge, the patients with short AF did not experience stroke and AF recurrence during follow-up, while those in the other group developed it (10.8%, P = 0.038 and 13.5%, P = 0.019, respectively). CONCLUSION: New-onset AF during AMI identifies the patients at long-term risk for stroke who may potentially benefit from anticoagulant therapy. Atrial fibrillation recurrence in follow-up was independently related to the development of stroke. However, for low-risk patients with AF (those with short AF occurring early in AMI) long-term anticoagulants might not be required.
