P4571PFA-100, a test of platelet adhesion/aggregation, predicts cardiovascular events after an acute coronary syndrome and can help in the decision-m…

2019

Abstract Background The dual antiplatelet therapy (DAPT) duration is a matter of great interest among cardiologists. Because of the conflicting evidences and the necessity to balance the reduction in major cardiac events (MACE) occurrence and the risk of major bleedings after an acute coronary syndrome (ACS), there is a general consensus on prolonging DAPT on an individual basis. There is less consensus on which parameters are to be evaluated. Nowadays tests of platelet reactivity are not included in the decision-making. Few data are available on the prognostic value of aspirin response tests that are sensitive to other mediators of platelet adhesion and aggregation in vivo under flow condi…

Impact of Diabetes and Impaired Glucose Tolerance (IGT) on Complications and Hospitalisation in Patients with Acute Coronary Syndrome

Impact of dual antiplatelet therapy with proton pump inhibitors on the outcome of patients with acute coronary syndrome undergoing drug-eluting stent…

2012

This study aimed to assess if proton pump inhibitors (PPIs) may reduce the effectiveness of clopidogrel, than H2 antagonist (anti-H2) in order to determine rehospitalization for acute coronary syndrome (re-ACS), target vessel revascularization (TVR) and cardiac death. This case-control study included 176 patients with ACS undergoing angioplasty (PCI) with drug-eluting stent implantation. The population was divided into two groups: PPI group (n=121) consisting of patients receiving at discharge dual antiplatelet therapy (DAT) plus PPI and anti-H2 group (n=55), consisting of patients receiving at discharge DAT + H2 receptor antagonist (H2RA). In a followup of 36 months the prevalence of ACS e…

Post-Infectious Myocardial Infarction: New Insights for Improved Screening

2019

Acute infection is suspected of involvement in the onset of acute myocardial infarction (MI). We aimed to assess the incidence, pathogenesis and prognosis of post-infectious MI. All consecutive patients hospitalized for an acute MI in coronary care units were prospectively included. Post-infectious MI was defined by a concurrent diagnosis of acute infection at admission. Type 1 MI (acute plaque disruption) or Type 2 MI (imbalance in oxygen supply/demand) were adjudicated according to the universal definition of MI. From the 4573 patients admitted for acute MI, 466 (10%) had a concurrent acute infection (median age 78 (66–85) y, 60% male), of whom 313 (67%) had a respiratory tract infection.…

Retinal optical coherence tomography angiography as a biomarker of acute kidney injury after acute coronary syndrome

2018

Background Contrast-induced nephropathy (CIN) after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) is frequent and associated with long-term renal impairment and mortality. Retinal vessel density (RVD) measured by OCT-Angiography could reflect the global cardiovascular burden of ACS patients and thus provide a fast and non-invasive assessment of the systemic microcirculation, that may be involved in CIN occurrence. Methods Between October 2016 and March 2017, 452 ACS patients were admitted in our coronary care unit. Retinal OCT-A was performed within two days after PCI. Patients were divided in two groups, according to Acute kidney injury (AKI) occurrence (KDIGO …

Coronary Stent Thrombosis — Predictors and Prevention

2020

BACKGROUND: Stent thrombosis (ST) is a dreaded complication after stent implantation and is associated with a mortality between 5% and 45%. The mechanisms by which ST arises are complex. Because of the seriousness of this situation, all physicians should have at least basic knowledge of it. In this article, we present the risk factors for ST and discuss some innovative approaches to its treatment. METHODS: This review is based on pertinent articles retrieved by a selective search in PubMed, and on current international guidelines and expert recommendations. RESULTS: The frequency of ST has been markedly lowered by technical advances in coronary stenting and by the implementation of modern i…

Psychological State after an Acute Coronary Syndrome: Impact of Physical Limitations

2021

The aim of this study was to investigate how physical limitations after ACS influence patients’ quality of life and health perception. This was a longitudinal clinical study. We recruited 146 patients diagnosed with ACS. The patients performed a stress test (Bruce’s protocol) for the evaluation of physical limitations and were classified according to the test result: without physical limitations (more than 10 METS), with some physical limitations (7 to 9 METS), and with high physical limitations (less than 6 METS). Significant differences were found between the three groups immediately after the diagnosis of ACS and after a period of three months, regarding health perception, anxiety, depre…

Cystatin C levels are decreased in acute myocardial infarction: Effect of cystatin C G73A gene polymorphism on plasma levels

2005

Background: Cystatin C is the most abundant protease inhibitor in the plasma. Low plasma levels have been found in patients with aortic aneurysms and they seem correlated with the extension of the aortic lesions in early aneurysms detected by ultrasonography. Methods: In this study, plasma levels of cystatin C have been investigated in patients with acute myocardial infarction (AMI), unstable angina and controls. The effect on plasma levels of the G73A polymorphism of the CST3 gene has been also evaluated. Results: Patients with acute myocardial infarction showed significantly lower levels of cystatin C compared to unstable angina and controls, but levels were nearly normal in a week after …
