Do Instrumental Variables Belong in Propensity Scores? [PDF]

Propensity score matching is a popular way to make causal inferences about a binary treatment in observational data. The validity of these methods depends on which variables are used to predict the propensity score.

Acute myocardial infarction complicated by cardiogenic shock: an algorithm based ECMO program can improve clinical outcomes. [PDF]

, 2016
Objective: Extracorporeal membrane oxygenation (ECMO) in our institution resulted in near total mortality prior to the establishment of an algorithm-based program in July 2010. We hypothesized that an algorithm based ECMO program improves the outcome of

Prevalence of Pulmonary Arterial Thrombosis in Adults With Eisenmenger Syndrome

Pulmonary Circulation, Volume 15, Issue 4, October 2025.
ABSTRACT Patients with Eisenmenger syndrome (ES) are at increased risk of thrombotic events, especially in pulmonary vessels. However, both the prevalence and risk factors of pulmonary arterial thrombosis (PAT) have been varied greatly. In this study we sought to examine the prevalence of PAT in adult patients with ES and to identify risk factors.

The Role of New Pulmonary Artery Wedge Pressure Formula to Predict Diastolic Dysfunction in Obstructive Sleep Apnea

Acta Medica Indonesiana, 2023
Background: Heart failure (HF) is a common condition with high morbidity and mortality  in  Obstructive Sleep Apnea (OSA), especially in obese patient. The causes of HF are often abnormal conduction pathways, pump filling and/or heart valves. Right heart

Coronary and systemic hemodynamic effects of intravenous nisoldipine [PDF]

, 1986
Systemic and coronary hemodynamic effects of the new dihydropyridine calcium antagonist nisoldipine were studied over a 30-minute period in 12 patients with angina pectoris. Previously instituted beta-blocker therapy was continued.

Artifact management methodologies for arterial blood pressure signals: A systematic scoping review of human and animal literature

Physiological Reports, Volume 13, Issue 19, October 2025.
Abstract Arterial blood pressure (ABP) is a broadly measured vital signal used to monitor cardiovascular health through raw signal and derived metrics. Artifacts are a pervasive issue, resulting in a declined utility of the signal. The aim of this review was to examine the existing literature pertinent to artifact management strategies in ABP signals ...

On the possibility to increase sensitivity of diagnostic tests for fixed pulmonary hypertension in heart transplant candidates

Alʹmanah Kliničeskoj Mediciny, 2019
Background: Fixed pulmonary hypertension (PH) in heart transplant candidates is a risk factor for right ventricular failure in the postoperative period and early mortality. Patients with fixed PH are not included in the waiting list.

Intra aortic balloon pumping in myocardial infarction and unstable angina [PDF]

, 1980
From 1972 to 1979 intra aortic balloon pumping (IABP) was attempted in 181 patients; catheter insertion failed in 13 (8%). More complications occurred with prolonged treatment but all three lethal complications (2%) were related to catheter insertion ...

Estimating Mean Pulmonary Wedge Pressure in Patients With Chronic Atrial Fibrillation From Transthoracic Doppler Indexes of Mitral and Pulmonary Venous Flow Velocity [PDF]

, 1997
Objectives. We sought to obtain a noninvasive estimation of mean pulmonary wedge pressure (MPWP) in patients with chronic atrial fibrillation (AF).Background. It has previously been demonstrated that MPWP can be reliably estimated from Doppler indexes of
