Causal inference in paired two-arm experimental studies under non-compliance with application to prognosis of myocardial infarction

open access: yes, 2012
Motivated by a study about prompt coronary angiography in myocardial infarction, we propose a method to estimate the causal effect of a treatment in two-arm experimental studies with possible non-compliance in both treatment and control arms.

Coronary Spasm Due to Pulsed Field Ablation: A State‐of‐the‐Art Review

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT With the ever‐growing population of patients undergoing cardiac ablation with pulsed electric fields, there is a need to understand secondary effects from the therapy. Coronary artery spasm is one such effect that has recently emerged as the subject of further investigation in electrophysiology literature.

Unstable Angina Pectoris

open access: yes, 1988
The introduction of intravenously administered nitrate formulations such as intravenous nitroglycerin and intravenous isosorbide dinitrate has markedly improved the conservative therapy of unstable angina. These formulations, originally used only in coronary care units, are now used in general medical wards and emergencies rooms, without hemodynamic ...

Vital systems, Grand body systems: Cardiovascular systems

open access: yesنشریه پرستاری ایران, 1995
Unstable angina has progressive process and even in rest time, it happens frequently. It is a serious situation and 15-20 percent of patients are dying in duration of one year. Treatment: patients often hospitalized because observation of their reactions

Reliability of Rapid On‐Site Evaluation Achieved by Remote Sharing Systems (E‐ROSE) and AI Algorithms (AI‐ROSE) Compared With the Gold Standard in the Diagnosis of Lung Cancer

open access: yesRespirology, EarlyView.
The use of sharing technology (E‐ROSE) and machine learning models (AI‐ROSE) could facilitate reliable rapid on‐site evaluation (ROSE) of cytology images. E‐ROSE has demonstrated high sensitivity and accuracy; similarly, AI‐ROSE has shown good performance. These tools could optimise diagnosis in centres without dedicated cytopathologists.

Submaximal 2‐day cardiopulmonary exercise testing to assess exercise capacity and post‐exertional symptom exacerbation in people with long COVID

open access: yesExperimental Physiology, EarlyView.
Abstract Long COVID has a complex pathology and a heterogeneous symptom profile that impacts quality of life and functional status. Post‐exertional symptom exacerbation (PESE) affects one‐third of people living with long COVID, but the physiological basis of impaired physical function remains poorly understood. Sixty‐eight people (age (mean ± SD): 50 ±

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

Correction of aggregative thrombocytes activity in patients with unstable angina by THz irradiation of nitrogen oxide occurrence at in vitro conditions

open access: yesRussian Open Medical Journal, 2013
There had been shown a normalizing effect of THz radiation of MEAS (molecular emission and absorption spectrum) of 400 GHz nitrogen oxide occurrence on aggregation parameters of thrombocytes in patients with unstable angina at in vitro conditions.

Gasotransmitters in Modern Medicine: Promises and Challenges in the Use of Porous Crystalline Carriers

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 26, October 7, 2025.
This perspective provides an overview of the growing interest in utilizing various gasotransmitters—small gaseous signaling molecules namely nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S)—for several therapeutic applications, with emphasis on the potential use of porous materials as carriers to provide safe and controlled local ...
