Variant Angina with Spontaneously Documented Ischemia- and Tachycardia-induced "Lambda" Waves.

Intern Med 2021 1;60(9):1409-1415. Epub 2021 May 1.

Department of Clinical Pathology, Yawatahama City General Hospital, Japan.

In a patient with variant angina of the proximal left anterior descending coronary artery, myocardial ischemia changed the QRS-ST-T configurations without J-waves into those resembling "lambda" waves at maximal ST-segment elevation, and couplets or triplets of supraventricular extrasystole (SVE) changed the ischemia-induced "lambda" waves into QRS-ST-T configurations resembling a "tombstone" morphology or "monophasic QRS-ST complex." At the resolution phase of coronary spasm, the QRS-ST-T configurations returned to those without J-waves and were changed by SVE into "lambda" waves. Interestingly, neither ischemia- nor SVE-induced "lambda" waves or SVE-induced "tombstone" morphology or "monophasic QRS-ST complex" were complicated by ventricular tachyarrhythmia. Read More

Nourin-Dependent miR-137 and miR-106b: Novel Biomarkers for Early Diagnosis of Myocardial Ischemia in Coronary Artery Disease Patients.

Diagnostics (Basel) 2021 Apr 14;11(4). Epub 2021 Apr 14.

Department of Surgery, UConn Health, School of Medicine, Farmington, CT 06032, USA.

Background: Although cardiovascular imaging techniques are widely used to diagnose myocardial ischemia in patients with suspected stable coronary artery disease (CAD), they have limitations related to lack of specificity, sensitivity and "late" diagnosis. Additionally, the absence of a simple laboratory test that can detect myocardial ischemia in CAD patients, has led to many patients being first diagnosed at the time of the development of myocardial infarction. Nourin is an early blood-based biomarker rapidly released within five minutes by "reversible" ischemic myocardium before progressing to necrosis. Read More

The Role of Oxidative Stress Markers in Predicting Acute Thrombotic Occlusion of Haemodialysis Vascular Access and Progressive Stenotic Dysfunction Demanding Angioplasty.

Antioxidants (Basel) 2021 Apr 8;10(4). Epub 2021 Apr 8.

Department of Medicine, Division of Nephrology and Hypertension, University of North Carolina, Chapel Hill, NC 27599, USA.

Haemodialysis vascular access (VA) dysfunction is a major cause of morbidity in haemodialysis (HD) patients. Primary venous outflow occlusion and restenosis after percutaneous transluminal angioplasty (PTA) are two major obstacles for the long-term use of dialysis VA.
