Prognosis of deferred non-culprit lesions according to fractional flow reserve in patients with acute coronary syndrome.

Joo Myung Lee et 12 al.

Oct 13, 2017 in EuroIntervention
There are limited data on the prognosis of deferred non-culprit lesions in patients with acute coronary syndrome (ACS) based on fractional flow reserve (FFR). We aimed to investigate the prognosis of deferred non-culprit lesions in ACS patients, compared with deferred lesions in patients with stable coronary artery disease (SCAD), on the basis of FFR. The clinical outcomes of 449 non-culprit lesio...


Discriminative Role of Invasive Left Heart Catheterization in Patients Suspected of Heart Failure With Preserved Ejection Fraction.

Ki Hong Choi, Eun-Seok Jeon et 15 al.

Mar 9, 2023 in Journal of the American Heart Association
Background Recently, diastolic stress testing and invasive hemodynamic measurements have been emphasized for diagnosis of heart failure with preserved ejection fraction (HFpEF) because when determined using noninvasive parameters it can fall into a nondiagnostic intermediate range. The current study evaluated the discriminative and prognostic roles of invasive measured left ventricular end-diasto...

Associations of albumin and nutritional index factors with delirium in patients admitted to the cardiac intensive care unit

Tae Wan Kim et 7 al.

Mar 3, 2023 in Frontiers in Cardiovascular Medicine
Background Limited data are available on the association of malnutrition with the occurrence of delirium in the cardiac intensive care unit (CICU). Thus, we aimed to analyze whether nutritional indices and their components can predict the development of delirium in CICU. Method We enrolled 2,783 patients admitted to the CICU of Samsung Medical Center for more than 24 h between September 2012 and D...


Prognosis after discontinuing renin angiotensin aldosterone system inhibitor for heart failure with restored ejection fraction after acute myocardial infarction.

Seung Hun Lee, Joo Myung Lee et 18 al.

Mar 2, 2023 in Scientific reports
Prognostic effect of discontinuing renin-angiotensin-aldosterone-system-inhibitor (RAASi) for patients with heart failure (HF) after acute myocardial infarction (AMI) whose left ventricular (LV) systolic function was restored during follow-up is unknown. To investigate the outcome after discontinuing RAASi in post-AMI HF patients with restored LV ejection fraction (EF). Of 13,104 consecutive patie...


Efficacy of thrombus aspiration in cardiogenic shock complicating acute myocardial infarction and high thrombus burden.

Woochan Kwon et 21 al.

Feb 4, 2023 in Revista espanola de cardiologia
Current guidelines do not recommend routine thrombus aspiration (TA) in acute myocardial infarction (AMI) because no benefits were observed in previous randomized trials. However, there are limited data in cardiogenic shock (CS) complicating AMI. We included 575 patients with AMI complicated by CS. The participants were stratified into the TA and no-TA groups based on use of TA. The primary outcom...

Safety and Efficacy of Everolimus-Eluting Bioresorbable Vascular Scaffold Versus Second-Generation Drug-Eluting Stents in Real-World Practice.

Joo Myung Lee et 30 al.

Feb 6, 2023 in Journal of Korean medical science
The risk of device thrombosis and device-oriented clinical outcomes with bioresorbable vascular scaffold (BVS) was reported to be significantly higher than with contemporary drug-eluting stents (DESs). However, optimal device implantation may improve clinical outcomes in patients receiving BVS. The current study evaluated mid-term safety and efficacy of Absorb BVS with meticulous device optimizati...


Prognostic Implications of Left Atrial Stiffness Index in Heart Failure Patients With Preserved Ejection Fraction.

Darae Kim et 7 al.

Dec 1, 2022 in JACC. Cardiovascular imaging
The left atrium (LA) plays an important role in the pathophysiology and disease progression of heart failure with preserved ejection fraction (HFpEF). This study sought to assess the prognostic potential of LA stiffness index in patients who have HFpEF. This study retrospectively screened patients with elevated left ventricular end-diastolic pressure (≥16 mm Hg) and preserved ejection fraction (≥5...


Prognostic Impact of Cardiac Diastolic Function and Coronary Microvascular Function on Cardiovascular Death.

David Hong, Joo Myung Lee et 13 al.

Jan 25, 2023 in Journal of the American Heart Association
Background Coronary microvascular dysfunction (CMD) has been considered as a possible cause of cardiac diastolic dysfunction. The current study evaluated the association between cardiac diastolic dysfunction and CMD, and their prognostic implications in patients without significant left ventricular systolic dysfunction and epicardial coronary stenosis. Method and Result A total of 330 patient...
