Professor Ki Hong Choi's research lab specializes in interventional cardiology and vascular medicine, with a strong focus on optimizing clinical outcomes in patients with acute coronary syndromes, peripheral artery disease, and cardiogenic shock. The lab investigates hemodynamic support strategies, such as VA-ECMO and inotropic support, and evaluates risk stratification tools like the Vasoactive Inotropic Score and PRECISE-DAPT score to personalize treatment in interventional cardiology. Their work also emphasizes the role of percutaneous revascularization techniques, including drug-eluting stents and endovascular therapy, particularly in complex coronary and peripheral vascular disease. The lab conducts large-scale, multicenter registries and clinical trials to inform evidence-based, patient-tailored interventions.
Figures are computed from collected data and may differ slightly.
Early initiation of VA-ECMO before revascularization therapy might improve clinical outcomes in patients with AMI complicated by refractory CS.
Background With advances in peripheral artery disease ( PAD ) treatments such as endovascular treatment ( EVT ), personalized patient assessment is important. Data on sex differences in clinical outcome for PAD patients undergoing EVT have been limited, and studies have produced conflicting results. This study sought to compare midterm clinical outcomes between women and men in a large population of patients with PAD undergoing EVT . Methods and Results The K- VIS ELLA (Korean Vascular Intervent
High Vasoactive Inotropic Score was associated with significantly higher in-hospital and follow-up mortality in patients with acute myocardial infarction complicated by cardiogenic shock. The predictive value of Vasoactive Inotropic Score for mortality was significantly higher in acute myocardial infarction patients with cardiogenic shock treated by medical treatment alone than in those treated by mechanical circulatory support such as intra-aortic balloon pump or extracorporeal membrane oxygena
HFpEF may indicate a better prognosis compared with HFrEF in ADHF, but not in de novo AHF. For patients with ADHF, the prognosis associated with HFmrEF was similar to that of HFpEF within the first year following hospitalisation and similar to HFrEF 1 year after hospitalisation.
Even in the second-generation drug-eluting stent era, the 1-stent strategy, if possible, should initially be considered the preferred approach for the treatment of LM bifurcation lesions. Registration: URL: https://www.clinicaltrials.gov. Unique identifier: NCT03068494.
Consistent with current guidelines, determination of the duration of DAPT according to PRECISE-DAPT score could improve the clinical outcomes in patients with acute coronary syndrome after percutaneous coronary intervention with current-generation drug-eluting stents.

Background Although current guidelines now define heart failure with midrange ejection fraction ( HF mr EF ) as HF with a left ventricular EF of 40% to 49%, there are limited data on response to guideline-directed medical therapy in patients with HF mr EF . The current study aimed to evaluate the association between β-blocker, renin-angiotensin system blocker ( RASB ), or aldosterone antagonist ( AA ) treatment with clinical outcome in patients with HF mr EF . Methods and Results We performed a
