[Ischemia with non-obstructive coronary artery disease: state-of-the-art review].

Chest pain affects more than 100 million people globally, however up to 70% of patients undergoing invasive angiography do not have obstructive coronary artery disease and ischemia with non-obstructive coronary artery disease (INOCA) is often a cause of the clinical picture. The symptoms reported by INOCA patients are very heterogeneous and often misdiagnosed as non-cardiac leading to under-diagnosis/investigation and under-treatment. The underlying pathophysiological mechanisms of INOCA are multiple and include coronary vasospasm and microvascular dysfunction.

The Underestimated Role of Platelets in Severe Infection a Narrative Review.

Beyond their role in hemostasis, platelets have emerged as key contributors in the immune response; accordingly, the occurrence of thrombocytopenia during sepsis/septic shock is a well-known risk factor of mortality and a marker of disease severity. Recently, some studies elucidated that the response of platelets to infections goes beyond a simple fall in platelets count; indeed, sepsis-induced thrombocytopenia can be associated with-or even anticipated by-several changes, including an altered morphological pattern, receptor expression and aggregation. Of note, alterations in platelet function and morphology can occur even with a normal platelet count and can modify, depending on the nature of the pathogen, the pattern of host response and the severity of the infection.

Methylation of SERPINA1 gene promoter may predict chronic obstructive pulmonary disease in patients affected by acute coronary syndrome.

Background: Diagnostic biomarkers for detecting chronic obstructive pulmonary disease (COPD) in acute coronary syndrome (ACS) patients are not available. SERPINA1, coding for the most potent circulating anti-inflammatory protein in the lung, has been found to be differentially methylated in blood cells from COPD patients. This study aimed to investigate the methylation profile of SERPINA1 in blood cells from ACS patients, with (COPD+) or without COPD (COPD-).

SERPINA1 Gene Promoter Is Differentially Methylated in Peripheral Blood Mononuclear Cells of Pregnant Women.

SERine Protein INhibitor-A1 (SERPINA1) is an inducible blood cell gene coding for alpha1-antitrypsin (AAT), a plasma protease inhibitor whose circulating levels are raised during inflammation, infection and advanced pregnancy. DNA methylation has been suggested to play a role in SERPINA1 gene expression regulation in peripheral blood mononuclear cells (PBMCs). The methylation status of in PBMCs is unknown.

[Bioresorbable vascular scaffolds: clinical experience of the Emilia-Romagna Region, Italy].

Background: The bioresorbable vascular scaffold (BRS) technology constitutes the new revolution of the coronary artery disease interventional treatment. Currently, three distinct types of BRSs are available but only one, the Absorb BVS, was on the market in 2013 when the Regional Commission for Medical Devices and the Cardiology and Cardiac Surgery Commission of the Emilia-Romagna Region drew up a technical and scientific essay to provide guidance for the introduction of BRS in public and affiliated health facilities. Five preferential indications were given for use: long coronary lesions (>28 mm), ostial lesions (left main stem excluded), complete revascularization in patients aged <50 years, diffuse disease (>40 mm) or involving the mid/distal left anterior descending (LAD) branch in patients <70 years, spontaneous coronary artery dissection.
