Percutaneous coronary intervention

BACKGROUND: This study aimed to evaluate the long-term outcomes of double kissing crush stenting (DKC) and mini-culotte technique (MCT) in patients with complex bifurcation lesions. METHODS: This retrospective study enrolled 236 patients who underwent percutaneous coronary intervention (PCI) for complex coronary bifurcation disease between January 2014 and November 2022. The primary endpoint was target lesion failure (TLF), defined as the combination of cardiac death, myocardial infarction (MI), or clinically driven target lesion revascularization (TLR)...

PURPOSE: Construction of a prediction model to predict the risk of major adverse cardiovascular events (MACE) in the long term after percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). METHOD: Retrospective analysis of STEMI patients treated with PCI from April 2018 to April 2021 in Fuyang People's Hospital. Lasso regression was used to screen the risk factors for the first occurrence of MACE in patients, and multifactorial logistic regression analysis was used to construct a prediction model...

Percutaneous coronary intervention (PCI) patients combined with thrombocytopenia (TP) are usually considered to be at low ischemic risk, receiving less proper antiplatelet therapy. However, recent studies reported a paradoxical phenomenon that PCI patients with TP were prone to experience thrombotic events, while the mechanisms and future treatment remain unclear. We aim to investigate whether inflammation modifies platelet reactivity among these patients. Consecutive 10 724 patients undergoing PCI in Fuwai Hospital were enrolled throughout 2013...

OBJECTIVE: This study aimed to compare the clinical outcomes of double kissing mini-culotte (DKMC) stenting with those of mini-culotte (MC) stenting in treating patients with true coronary bifurcation lesions (CBLs) in the clinical real world. METHODS: This retrospective observational cohort study included 180 consecutive patients with true CBLs (Medina type 1,1,1; 1,0,1; 0,1,1). All eligible patients underwent coronary angiography and percutaneous coronary intervention with two-stent techniques in our hospital; among them, 97 received DKMC treatment and 83 MC treatment...

Background: Medication adherence in patients after percutaneous coronary intervention (PCI) is suboptimal, and discontinuation is common. Information on the temporal characteristics and associated factors of discontinuation and outcomes after PCI is insufficient to improve medication adherence interventions. Methods: We conducted a single-center retrospective study of post-PCI patients by telephone survey and medical record extraction. Temporal characteristics and associated factors of discontinuation and outcomes were examined by survival curve analysis, Cox regression, or time-dependent Cox regression...

OBJECTIVES: In recent years, the free triiodothyronine/free thyroxine (FT3/FT4) ratio, a new comprehensive index for evaluating thyroid function, which could reflect thyroid function more stably and truly than serum thyroid hormone level, has been demonstrated to correlate with the risks of diabetes and cardiovascular disease in euthyroid adults. However, the correlation between thyroid hormone sensitivity and long-term prognosis in euthyroid patients with acute coronary syndrome (ACS) and diabetes after percutaneous coronary intervention (PCI) remains unclear...

BACKGROUND: Acute kidney injury (AKI) is a frequent and potentially life-threatening complication after percutaneous coronary intervention (PCI) in patients with ST-segment-elevation myocardial infarction (STEMI). However, the relationship between obesity and the risk of AKI in this specific patient population has not been previously examined. METHODS: We queried the National Inpatient Sample (2016-2019) using ICD-10 codes to obtain a sample of adults with STEMI undergoing PCI...

BACKGROUND AND OBJECTIVES: Concerns remain that early aspirin cessation may be associated with potential harm in subsets at high risk of ischemic events. This study aimed to assess the effects of P2Y12 inhibitor monotherapy after 3-month dual antiplatelet therapy (DAPT) vs. prolonged DAPT (12-month or longer) based on the ischemic risk stratification, the CHADS-P2A2RC, after percutaneous coronary intervention (PCI). METHODS: This was a sub-study of the SMART-CHOICE trial...

BACKGROUND: Shockwave intravascular lithotripsy (S-IVL) is widely used during percutaneous coronary intervention (PCI) of calcified coronary arteries. Ventricular capture beats during S-IVL are common but arrhythmias are rare. CASE PRESENTATION: A 75-year-old woman was scheduled for PCI to a short, heavily calcified chronic total occlusion of the right coronary artery. After wiring of the occlusion, S-IVL was used to predilated the calcified stenosis. During S-IVL, the patient developed ventricular fibrillation twice...

The objective of this study was to investigate patient radiation doses by a dose audit of three common interventional cardiology (IC) procedures: coronary angiography (CA), percutaneous transluminal coronary angioplasty (PTCA) and CA-PTCA procedures performed in IC centres in the Uttarakhand state of India, for the establishment of local diagnostic reference levels (DRLs) and the estimation of average effective dose (Eav ) for these procedures. For each procedure, the values of kerma-area product (PKA ), reference air kerma (Ka,r ), fluoroscopy time (FT) and the number of cine images were recorded from 1233 CA, 458 PTCA and 736 CA-PTCA procedures performed over a 12-month period at 13 IC centres of the state...

BACKGROUND: Little is known about the safety and efficacy of discontinuing antiplatelet therapy via LMWH bridging therapy in elderly patients with coronary stents implanted for > 12 months undergoing non-cardiac surgery. This randomized trial was designed to compare the clinical benefits and risks of antiplatelet drug discontinuation via LMWH bridging therapy. METHODS: Patients were randomized 1:1 to receive subcutaneous injections of either dalteparin sodium or placebo...

BACKGROUND: IgG4-related disease (IgG4-RD) is a recently recognized fibro-inflammatory disorder that can affect almost any organ. IgG4-RD has also been reported in coronary arteries as periarteritis. IgG4-related coronary periarteritis may cause coronary artery aneurysms, and IgG4-related coronary artery aneurysms (IGCAs) are life-threatening. We describe a case of a patient with IGCA that highlights the usefulness and limitations of various IGCA evaluation modalities and provides insight into disease pathophysiology...

BACKGROUND: Coronary heart disease is one of the leading causes of mortality worldwide. Secondary prevention is essential, as it reduces the risk of further coronary events. Mobile health (mHealth) technology could become a useful tool to improve lifestyles. OBJECTIVE: This study aimed to evaluate the effect of an mHealth intervention on people with coronary heart disease who received percutaneous coronary intervention. Improvements in lifestyle regarding diet, physical activity, and smoking; level of knowledge of a healthy lifestyle and the control of cardiovascular risk factors (CVRFs); and therapeutic adherence and quality of life were analyzed...

UNLABELLED: A man in his 70s with a history of mitral valve replacement (MVR) and long-standing persistent atrial fibrillation (AF) presented with effort angina. Coronary angiography revealed severe stenosis of the left main coronary artery (LMCA). As it was an emergent case, PCI (percutaneous coronary intervention) was selected for treatment. Intravascular ultrasonography revealed no atherosclerotic lesions in the LMCA. The LMCA was effectively dilated by the drug-eluting stent. No elevation in intracardiac pressure was observed in cardiac catheterization after PCI...

BACKGROUND: The anticoagulation and risk factors in atrial fibrillation (ATRIA) score is associated with adverse cardiovascular events. However, its relationship with coronary thrombus burden is unclear. Therefore, we aimed to investigate the relationship between the ATRIA score and thrombus burden in patients with ST-segment elevation myocardial infarction (STEMI) who underwent percutaneous coronary intervention (PCI). MATERIALS AND METHODS: The study was designed as a prospective cross-sectional observational study...

AIMS: To evaluate the effects of initiating sodium-glucose cotransporter-2 (SGLT2) inhibitors on cardiorenal outcomes and mortality compared to dipeptidyl peptidase-4 (DPP-4) inhibitors as active comparators in patients diagnosed with type 2 diabetes with a history of percutaneous coronary intervention (PCI). MATERIALS AND METHODS: We used an active-comparator, new-user design and nationwide data from the National Health Insurance Service in South Korea from 2014 to 2019...

The occurrence of in-stent restenosis (ISR) poses a significant challenge for percutaneous coronary intervention (PCI). Thus, the promotion of vascular reendothelialization is essential to inhibit endothelial proliferation. In this study, we clarified the mechanism by which Detoxification and Activating Blood Circulation Decoction (DABCD) promotes vascular reendothelialization to avoid ISR by miRNA-126-mediated modulation of the vascular endothelial growth factor (VEGF) signaling pathway. A rat model of post-PCI restenosis was established by balloon injury...

Around 10% of patients with acute coronary syndrome are treated by vitamin K antagonists or non-vitamin K antagonist oral anticoagulants for various indications. The initial management of these patients is highly complex, and new guidelines specify that, only during percutaneous coronary intervention, a bolus of unfractionated heparin is recommended in one of the following circumstances: (1) if the patient is receiving a non-vitamin K antagonist oral anticoagulant; or (2) if the international normalized ratio is<2...
