Impact of Coronary Microvascular Dysfunction on Left Ventricular Function After Percutaneous Coronary Intervention: Assessment With Combined Dipyridamole‐Exercise Stress and Myocardial Strain/Work

open access: yesEchocardiography, Volume 43, Issue 3, March 2026.
Decreased coronary flow velocity reserve (CFVR) was correlated with left ventricular (LV) dysfunction after percutaneous coronary intervention (PCI), as assessed via dipyridamole‐exercise stress echocardiography (DExE). This dysfunction was characterized by lower myocardial strain/work index and worse 1‐year Seattle Angina Questionnaire (SAQ) scores ...

Leukoencephalopathy, a Frequent Complication After High‐Dose Methotrexate in Treatment of Osteosarcoma

open access: yesPediatric Blood &Cancer, Volume 73, Issue 1, January 2026.
ABSTRACT Background Methotrexate‐associated leukoencephalopathy is poorly documented in osteosarcoma. Since 2007, our institution has monitored osteosarcoma patients with sequential magnetic resonance imaging (MRI) and neuropsychological evaluations during treatment and follow‐up.

Dibutyryl cAMP, aminophylline, and beta-adrenergic agonists protect against pulmonary edema caused by phosgene

open access: yes, 1989
Phosgene is a toxic oxidant gas that causes the adult respiratory distress syndrome in exposed workers. Phosgene exposure markedly increased lung weight gain in buffer-perfused isolated rabbit lungs (31 +/- 5 g over 60 min after phosgene vs. 7.7 +/- 1.2

Why Temporary Pacing in Acute Inferior Myocardial Infarction or No‐Reflow Becomes a Trigger—Not a Remedy—For Ventricular Fibrillation: Undersensing, “R‐On‐T”, Catheter Trauma and the Ischaemic Substrate

open access: yesAnnals of Noninvasive Electrocardiology, Volume 31, Issue 1, January 2026.
Temporary pacing during acute inferior MI can paradoxically trigger VF via four mechanisms; the authors advocate reversing ischaemia before inserting a wire. ABSTRACT Temporary pacing during acute inferior MI or no‐reflow can trigger ventricular fibrillation rather than prevent it. Four mechanisms are highlighted: (1) acute ischemia lowers VF threshold

Aminophylline increases submaximum power but not intrinsic velocity of shortening of frog muscle

open access: yes, 1992
We hypothesized that methylxanthines, such as aminophylline, increase the power developed by submaximally activated frog skeletal muscles by increasing the force developed at any given velocity of shortening. Frog semitendinosus muscles were excised and

Effects and mechanism of action of aminophylline on cardiac function and regional blood flow distribution in conscious dogs.

open access: yes, 1981
The effects of aminophylline, 1 mg/kg/min infused intravenously for 10 minutes, were examined on left ventricular (LV) diameter, pressure, an indexes of myocardial contractility, as well as systemic, coronary and regional hemodynamics in conscious dogs ...

Myocarditis in the Modern Era: Navigating Diagnosis, Innovative Treatments, the COVID‐19 Challenge and the Role of Artificial Intelligence

open access: yesCardiology Research and Practice, Volume 2026, Issue 1, 2026.
Myocarditis is an inflammatory disease of the myocardium with diverse aetiologies, ranging from infections and autoimmune processes to drug‐induced reactions. Clinical manifestations vary widely from mild chest discomfort to life‐threatening complications such as acute heart failure, cardiogenic shock and sudden cardiac death. Although the diagnosis of
