Aims: Functional alterations of epicardial coronary arteries or coronary microcirculation represent a frequent cause of myocardial infarction and non-obstructive coronary arteries (MINOCA). We aimed at assessing the prognostic value of intracoronary provocative tests in patients presenting with MINOCA and in which other causes of MINOCA have been excluded. Methods and results: We prospectively evaluated patients with a diagnosis of MINOCA, excluding patients with aetiologies other than suspected coronary vasomotor abnormalities...

Coronary artery perforation (CAP) is a rare, but potentially mortal possible complication of percutaneous coronary intervention. There are several treatment options for this complication, including prolonged balloon dilatation, use of a coronary stent graft, and bypass surgery. In this case report, a 65-year-old female patient who was admitted to the catheter laboratory with a diagnosis of acute coronary syndrome, was presented. Coronary angiography revealed total occlusion in the mid segment of the right coronary artery and a drug-eluting stent was implanted under 12 atm of pressure following pre-dilatation with a perfusion balloon...

Twenty-five years ago, non-isotopic immunoassays for measuring the cardiac specific isoforms of troponin I (cTnI) and T (cTnT) were developed. Both biomarkers radically changed the diagnosis, prognosis, and therapy indication of acute coronary syndromes (ACS) and, particularly, of myocardial infarction (MI). However, cardiac troponins (cTn) rapidly demonstrated their usefulness in other cardiac and non-cardiac conditions, a part of the ischemic coronary diseases. Consequently, the number of patients to be tested for cTn and the number of tests requested to clinical laboratories sharply increased...

Intravascular imaging plays a key role in the identification of mechanisms of acute coronary syndromes Post processing IVUS algorithms (IMAP-IVUS and VH-IVUS) for tissue characterization have not been widely adopted due to current limitations Future development will allow easier, faster, and more accurate identification of vulnerable plaques, ultimately allowing prognostication of various interventions.

BACKGROUND: The use of the potent oral P2Y12 inhibitors prasugrel and ticagrelor in patients with acute coronary syndromes (ACS) has a favorable net clinical effect compared with clopidogrel and is recommended as first-line therapy. However, the impact of these agents on ischemic and bleeding events in elderly ACS patients is not well defined. METHODS: We performed a systematic review of articles comparing potent P2Y12 inhibitors to clopidogrel in elderly and nonelderly patients (defined according to each study) with ACS in terms of efficacy (composite of cardiovascular death, myocardial infarction, or stroke) and safety (major bleeding) end points...

Laboratories are looking for ways that they can identify and deliver value through their service rather than just provide high quality test results. One way to demonstrate value has been described in the form of a value proposition where the application of a laboratory test is described explicitly in terms of the process of care and the patient outcomes. We have applied this concept to the use of high sensitive troponin assays for the assessment of patients with suspected acute coronary syndrome. From a previously described framework we use a checklist to describe the various steps in the complete intervention or clinical pathway, demonstrating how the test should be used, highlighting key evidence in the literature that supports the intervention and list some of the measures which can be used to assess how well the intervention is being adopted and implemented...

The incidence of Cardiac (Cardio-Pulmonary) Arrest (CA) in the Catheterization Laboratory is not common. However, not only does it happen occasionally but its frequency tends to increase due to the increase in the overall number and complexity of interventions performed by interventional cardiologists. Therefore, certified knowledge and application of the ALS (Advanced Life Support) protocols by trained Catheterization Laboratory staff is imperative in many countries, by local Hospital standards and also by Law...

Coronary artery disease (CAD) is the most common manifestation of CVD and the acute coronary syndrome (ACS) is associated with a substantial morbidity and mortality in most populations globally. There are several biomarkers for diagnosis of MI. Troponin is routinely used as a biomarker in patients with chest pain, but it lacks sensitivity in the first hours of onset of symptoms, and so there is still a clinical need for new biomarkers for the diagnosis of CAD events. Recent studies have shown that miRNAs are involved in atherosclerotic plaque formation and their expression is altered during CAD events...

BACKGROUND: Patients after cardiac arrest or in cardiogenic shock due to acute coronary syndrome (ACS) are at high risk for stent thrombosis (ST) and recurrent cardiovascular events after primary percutaneous coronary intervention (PCI). High post-interventional platelet reactivity (HPR) might be an additional risk factor for ST in these critically ill patients. METHODS: Between 2006 and 2016, 401 critically ill patients from a cardiologic intensive care unit underwent platelet function testing after primary PCI using whole blood impedance aggregometry...

The troponin I (TnI) level is essential in the diagnosis of acute myocardial infarction, but may be elevated by other cardial and non-cardial causes. We report a 32-year-old pregnant woman admitted to hospital because of chest pain and dyspnoea. TnI levels were significantly elevated, although there was no suspicion of acute coronary syndrome or myocarditis, and supplementary diagnostics excluded pulmonary embolism. The TnI level was found to be falsely elevated due to immunoassay interference. We stress the need to be aware of the possibility of false positive TnI, especially during pregnancy...
