Fractional Flow Reserve Directed Percutaneous Coronary Intervention Optimization Using High‐Definition Intravascular Ultrasound in Non‐ST‐Segment Elevation Acute Coronary Syndrome Versus Chronic Coronary Syndrome

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular ultrasound (IVUS)‐guided optimization of suboptimal fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) results in a significant increase in both post‐PCI FFR and minimal lumen and stent areas (MLA and MSA, respectively).

Myocardial Infarction and All‐Cause Mortality Following Percutaneous Coronary Intervention Versus Conservative Treatment of Chronic Total Occlusions: A West Denmark Heart Registry Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Chronic coronary total occlusions (CTO) represent a therapeutic challenge, and results of randomized clinical trials and observational studies comparing conservative treatment versus percutaneous coronary intervention (PCI) are underpowered.

Instrumental Variables with Time-Varying Exposure: New Estimates of Revascularization Effects on Quality of Life [PDF]

arXiv
The ISCHEMIA Trial randomly assigned patients with ischemic heart disease to an invasive treatment strategy centered on revascularization with a control group assigned non-invasive medical therapy. As is common in such ``strategy trials,'' many participants assigned to treatment remained untreated while many assigned to control crossed over into ...

Comparison of Fractional Flow Reserve and Myocardial Perfusion Imaging in Saphenous Vein Grafts

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Revascularization decision‐making for saphenous vein grafts (SVGs) relies on angiographic lesion severity estimation, as studies on fractional flow reserve (FFR) for detecting ischemia in SVGs are scarce. Aims To compare FFR and quantitative coronary angiography (QCA) of SVGs against myocardial perfusion imaging (MPI) and to ...

Machine Learning-Based Model for Postoperative Stroke Prediction in Coronary Artery Disease [PDF]

arXiv
Coronary artery disease remains one of the leading causes of mortality globally. Despite advances in revascularization treatments like PCI and CABG, postoperative stroke is inevitable. This study aims to develop and evaluate a sophisticated machine learning prediction model to assess postoperative stroke risk in coronary revascularization patients.This

Incidence and 1‐Year Prognostic of Unstable Angina After High‐Sensitivity Troponin Assessment

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Incidence and prognostic of unstable angina after high‐sensitivity troponin assesment is controversial. Aims This study evaluated prognostic of a contemporary population of patients with UA defined using high sensitive T troponin (T hs‐cTn) measurements and with significant coronary artery disease (CAD). Methods Consecutive patients

The correlation of the society for vascular surgery wound, ischemia, and foot infection threatened limb classification with amputation risk and major clinical outcomes

Indian Journal of Vascular and Endovascular Surgery, 2018
The Society for Vascular Surgery Wound, Ischemia, and foot Infection (WIfI) threatened limb classification more comprehensively describes the extent of limb threat in patients with chronic limb-threatening ischemia than many previous classification ...

Early Risk Assessment Model for ICA Timing Strategy in Unstable Angina Patients Using Multi-Modal Machine Learning [PDF]

arXiv
Background: Invasive coronary arteriography (ICA) is recognized as the gold standard for diagnosing cardiovascular diseases, including unstable angina (UA). The challenge lies in determining the optimal timing for ICA in UA patients, balancing the need for revascularization in high-risk patients against the potential complications in low-risk ones ...

Impact of Diabetes on Long‐Term Outcomes of Percutaneous Coronary Intervention for Coronary Bifurcation Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Diabetes mellitus (DM) is a well‐known risk factor for cardiovascular diseases, including coronary artery diseases (CAD). Complex percutaneous coronary intervention (PCI) such as PCI for bifurcation lesions often yields poor outcomes, especially in DM patients.
