Survival benefit from recent changes in management of men and women with ST-segment elevation myocardial infarction treated with percutaneous coronar…
2019
Background: Nowadays, the majority of patients with myocardial infarction with ST-segment elevation (STEMI) are treated with primary percutaneous coronary interventions (PCI). In recent years, there have been ongoing improvements in PCI techniques, devices and concomitant pharmacotherapy. However, reports on further mortality reduction among PCI-treated STEMI patients remain inconclusive. The aim of this study was to compare changes in management and mortality in PCI-treated STEMI patients between 2005 and 2011 in a real-life setting. Methods: Data on 79,522 PCI-treated patients with STEMI from Polish Registry of Acute Coronary Syndromes (PL-ACS) admitted to Polish hospitals between 2005 an…
Dynamics and implications of circulating anti-angiogenic VEGF-A
2017
Angiogenesis is crucial to restore microvascular perfusion in the jeopardized myocardium in the weeks following reperfused ST-segment elevation myocardial infarction (STEMI). (VEGF)-A165b, an anti-angiogenic factor, has been identified as a regulator of vascularization; however, it has not been previously implicated in acute myocardial infarction. We sought to investigate the dynamics of circulating VEGF-A165b and its association with cardiac magnetic resonance-derived infarct size and left ventricular ejection fraction (LVEF). 50 STEMI patients and 23 controls were included. Compared with control individuals, serum VEGF-A165b was elevated in STEMI patients prior to primary percutaneous cor…
Long-term outcome of dental implants after maxillary augmentation with and without bone grafting
2016
Background: This study aims to evaluate the technique of sinus bone reformation, which consists of elevating the sinus membrane and placement the implant without bone graft, compared with the widely-used technique involving raising the maxillary sinus and grafting, using animal hydroxyapatite as the filler, while simultaneously fixing the implants. Material and Methods: This is a retrospective study on two groups of patients who underwent elevation of the sinus membrane and simultaneous placement of the implant. The grafting technique was applied to one group, while the other had no graft. An alveolar ridge height of 4 to 7 mm was necessary. Radiological control was undertaken at 6 months a…
Homocysteine and long-term recurrent infarction following an acute coronary syndrome.

Chorro, Juan Sanchis y Julio Núñez. Background: There are no well-established predictors of recurrent ischemic coronary events after an acute coronary syndrome (ACS). Higher levels of homocysteine have been reported to be associated with an increased atherosclerotic burden. The primary endpoi…
Influence of Comorbid Conditions on One-Year Outcomes in Non–ST-Segment Elevation Acute Coronary Syndrome
2011
To investigate comorbid conditions with prognostic influence in non-ST-segment elevation acute coronary syndrome (NSTEACS).The study group consisted of a derivation cohort of 1017 patients (admitted from October 1, 2002, through October 1, 2008) and an external validation cohort of 652 patients (admitted from February 1, 2006, through September 30, 2009). Comorbid conditions, including risk factors and components of the Charlson comorbidity index (ChCI) and coronary artery disease-specific index, were recorded. The main outcome was one-year mortality.During follow-up, 103 patients died. After adjusting for variables associated with NSTEACS characteristics (base model), 5 comorbid conditions…

Incidence, Predictors, and Impact on Six-Month Mortality of Three Different Definitions of Contrast-Induced Acute Kidney Injury After Coronary Angiog…
2017
We assessed incidence, predictors, and impact on 6-month mortality of contrast-induced acute kidney injury (CI-AKI) after coronary angiography with or without percutaneous coronary intervention in patients with acute coronary syndrome (ACS), according to 3 different CI-AKI definitions. Serum creatinine (sCr) was assessed at baseline and 48 to 72 hours after procedure to classify patients into 3 CI-AKI groups: Group 1: increase in sCR ≥25% over baseline but absolute increase 25% in the remaining 844 (84.2%). CI-AKI was significantly associated with 6-month all-cause mortality using the definitions for Group 2 (hazard ratio 3.1, 95% confidence interval [CI] 1.5 to 6.6, p = 0.002) and Group 3 …
Causes of ineligibility in randomized controlled trials and long-term mortality in patients with non-ST-segment elevation acute coronary syndromes
2006
To determine the long-term mortality of patients with non-ST-segment elevation acute coronary syndromes (NSTEACS) that are eligible versus those not eligible in randomized controlled trials (RCT), and how each exclusion criteria is associated with outcome.Common causes of exclusion in six published RCT on intravenous antithrombotic therapy were prospectively assessed in a cohort of 452 consecutive patients with NSTEACS that were followed for up to 3 years.Forty-one percent of patients had one or more exclusion criteria establishing the ineligible group. These patients were older, more likely to have coronary risk factors, ischemic ECG changes, heart failure at admission, higher creatinine l…
Cardiac Troponins for the Diagnosis of Acute Myocardial Infarction in Chronic Kidney Disease
2018
Background Patients with chronic kidney disease ( CKD ) are at high risk of myocardial infarction. Cardiac troponins are the biomarkers of choice for the diagnosis of acute myocardial infarction ( AMI ) without ST ‐segment elevation ( NSTE ). In patients with CKD , troponin levels are often chronically elevated, which reduces their diagnostic utility when NSTE ‐ AMI is suspected. The aim of this study was to derive a diagnostic algorithm for serial troponin measurements in patients with CKD and suspected NSTE ‐ AMI . Methods and Results Two cohorts, 1494 patients from a prospective cohort study with high‐sensitivity troponin I (hs‐ cTnI ) measurements and 7059 cases from a clinical registr…
Sensitivity, specificity and predictive value of the echocardiography and troponin-T test combination in patients with non-ST elevation acute coronar…
2004
Introduction: Patients with a negative troponin (TnT) result showed 1.4% mortality during a mean follow-up of 9–10 weeks. Mortality was greater in patients with an evidence of ischemic ECG changes and a negative TnT test (1.6–4.4%). Few studies have examined the efficacy of echocardiography (2DE) in patients with chest pain. The purpose of the present study was to determine the clinical utility, sensitivity and specificity of the combination of TnT levels and 2DE in patients presenting with chest pain, ST-depression, T-wave negative and no diagnostic ECG. Methods: 280 consecutive patients with chest pain and presence of ST depression, T-wave inversion, and non-diagnostic ECG, acceptable 2DE…
