Oral Glycoprotein IIb/IIa Antagonists for Unstable Angina — Is There Still a Chance for the Oral Substances?

2001

The intravenous glycoprotein IIb/IIIa antagonists abciximab, tirofiban and eptifibatide are well accepted for the therapy of patients with unstable angina and/or as concomitant medication during coronary interventions. Despite the fact that these drugs are not used in all patients presenting with unstable angina during coronary interventions, the scientific evidence is overwhelming including the substantial reduction in mortality 3 years after utilisation of abciximab for coronary interventions in patients with unstable angina. In addition to these two indications, intravenous glycoprotein IIb/IIIa antagonists are currently being investigated for use in patients undergoing carotid artery in…

Impact of diabetes mellitus on outcomes in patients with myocardial infarction according to varying degrees of left ventricular systolic dysfunction.

2022

Background: Diabetes mellitus (DM) is known to contribute to unfavorable short- and long-term outcomes in patients with myocardial infarction (MI). Particularly poor outcomes are associated with left ventricular systolic dysfunction after an MI. The aim of our study was to compare the short- and long-term outcomes of MI in patients with DM and varied degrees of left ventricular systolic dysfunction with the corresponding outcomes in a non-diabetic control group. Methods: This analysis focused on patients with MI registered in the Polish National Registry of Acute Coronary Syndrome between 2009 and 2011. For the purposes of this analysis, diabetic patients were additionally stratified into t…

MR imaging of bilateral paramedian thalamic and mesencephalic infarcts: A case report

2010

We describe MR imaging of bilateral infarction of the paramedian portion of the mesencephalus and thalamus due to an occlusion of the Percheron artery. This entity is due to one of the anatomic variants of the perforating arteries supplying the thalamus and mesenchephalus. Clinically this kind of infarction presents with neurologic impairment as a disorder of consciousness, memory dysfunctions, various types of vertical gaze palsy and psychic changes, which need to be differentiated from delirium and coma. At MRI evaluation infarction of the paramedian portion of thalami and midbrain, with a “butterfly wings” pattern, was demonstrated as high signal intensity areas on FLAIR and FSE-T2W ima…

Strict compliance with ESC therapeutic guidelines after myocardial infarction treated with invasive strategy correlates with improved 18-month outcom…

2020

Abstract Background Despite improved early outcomes in patients (pts) with acute myocardial infarction (MI) in Poland with prevalent strategy of primary angioplasty by radial access, mid- and long-term outcomes are unsatisfactory. Objective We hypothesized that strict implementation of secondary prevention ESC guidelines in post-infarction management may be related with improved mid-term clinical outcomes Methods We compared 18-month outcomes of pts treated for MI with primary invasive strategy in a tertiary university hospital (NSTEMI 470/47%, or STEMI 535/53%; N=1005; Gr-L) with similar subset from national databases AMI-PL and PL-ACS (N=117307; NSTEMI 50966/43%, STEMI 64078/57%; Gr-Pol).…

One crucial parameter to evaluate the state of the heart after myocardial infarction (MI) is the viability of the myocardial segment, i.e., if the segment recovers its functionality upon revascularization. MRI performed several minutes after the injection of a contrast agent (delayed enhancement-MRI or DE-MRI) is a method of choice to evaluate the extent of MI, and by extension, to assess viable tissues after an injury. The Emidec dataset is composed of a series of exams with DE-MR images in short axis orientation covering the left ventricle from normal cases or patients with myocardial infarction, with the contouring of the myocardium and diseased areas (if present) from experts in the dom…

Cardiac threat appraisal and depression after first myocardial infarction

2012

The present study investigated cardiac threat appraisal and its association with depression after first myocardial infarction (MI). A semi-structured interview allowing for DSM-IV-Axis I diagnoses was administered to 36 patients after first MI. Patients completed self-reports 5 to 15 days after the MI (time 1), 6 to 8 weeks later (time 2) and again 6 months later (time 3). Assessments at time 1 included indices of cardiac threat appraisal, locus of control, coping, and depression while at time 2 and time 3 only measures of depression were obtained. Cardiac threat appraisal was significantly correlated with depression at time 1, but was unrelated to depression scores at time 2 and time 3. Fu…

Isolated non-compaction of the myocardium as a cause of coronary and cerebral embolic events in the same patient.

2009

A 44-year-old woman with a history of smoking and previous cerebral thrombo-embolism presented to the emergency department with prolonged chest pain and ECG changes showing an acute anterior myocardial infarction. She was referred to the cath-lab for primary angioplasty. Coronary angiography showed a thrombotic occlusion at the origin of first diagonal …

Long-term outcome of patients with NSTEMI and nonobstructive coronary arteries by different angiographic subtypes

2021

Discordant data have been reported on the prognosis of myocardial infarction with nonobstructive coronary arteries (MINOCA). Moreover, few data are available on the impact of angiographic subtypes. The objectives of this study were to assess the prognostic impact on the long-term follow-up of the diagnosis of MINOCA and its angiographic subtypes.We included 591 consecutive patients with non-ST-segment elevation myocardial infarction (NSTEMI) who underwent coronary angiography. MINOCA was classified according to angiographic findings as smooth coronary arteries, mild irregularities (30% stenosis), and moderate atherosclerosis (30%-49% stenosis). The primary endpoint was a composite of mortal…

Lesions of Proximal Coronary Arteries

2009

Coronary artery disease (CAD) remains the leading cause of death in the Western world. Conventional coronary angiography (CCA) is the gold standard method for evaluation of the vascular lumen and provides excellent results in demonstrating stenotic lesions of CAD. However, it is an invasive procedure with a small risk of fatal events. Furthermore, CCA is a lumen-oriented technique that does not permit a direct visualization and evaluation of the coronary artery wall. The characterization of coronary plaques without a significant lumen narrowing is also not feasible with CCA. This information is relevant since the comparison of angiographic studies of coronary arteries performed before and a…
