The impact of statins treatments for plaque characteristics in stable angina pectoris patients with very low and high low-density lipoprotein cholesterol levels: an intracoronary optical coherence tomography study.

Low-density lipoprotein cholesterol (LDL-C) levels are recommended according to the patient's risk factors based on guidelines. In patients achieving low LDL-C levels, the need for statins is uncertain, and the plaque characteristics of patients not treated with statins are unclear. In addition, the difference in plaque characteristics with and without statins is unclear in similarly high LDL levels.

The Inhibitory Effect of Platelet Aggregation Ability Assessed by the Platelet Aggregatory Threshold Index in a Patient with Recurrent Stent Thrombosis.

An 86-year-old man successfully underwent percutaneous coronary intervention (PCI), in which a drug-coated stent (DCS) was placed in the left anterior descending coronary artery. However, stent thrombosis occurred twice after eight and two months. After the second admission, the patient was tested for platelet aggregation activity using the platelet aggregation threshold index (PATI), and insufficient inhibition of platelet aggregation was observed.

Clinical Outcomes of Patients with Chronic Kidney Disease Undergoing Percutaneous Coronary Interventions with a Novel Dynamic Coronary Roadmap System.

Dynamic coronary roadmap (DCR) is a novel technology that creates a real-time overlay of the coronary arteries in percutaneous coronary intervention (PCI) and has the potential to reduce the contrast volume. However, the efficacy of DCR in terms of clinical outcomes in patients with chronic kidney disease (CKD) remains to be fully elucidated.This single center retrospective study enrolled 275 patients with CKD who underwent PCI, and divided them into a DCR group (n = 124) and Non-DCR group (n = 151).

The antiplatelet drug prasugrel inhibits platelet aggregation early after oral administration. This study examined whether prasugrel is effective in inhibiting infarct size and can reduce the incidence of major adverse cardiovascular events (MACE) in patients with acute coronary syndrome (ACS). This study was a single-center, prospective, randomized pilot study.

Urinary liver-type fatty acid-binding protein: A hemodynamic index during extracorporeal membrane oxygenation.

We discuss a case in which urinary L-FABP measurements were used to manage a 46-year-old male patient receiving V-A ECMO support. His mean blood pressure was ≥75 mmHg for the first 24 h after the initiation of V-A ECMO, and he experienced a rapid decrease in urinary L-FABP levels.

Combined assessment of frailty and nutritional status can be a prognostic indicator after percutaneous coronary intervention.

The cardiac prognosis of patients with frailty and malnutrition remains poorly investigated. This study aimed to investigate the impact of frailty and malnutrition on cardiac prognosis by combining the clinical frailty scale (CFS) and the geriatric nutritional risk index (GNRI) in patients who underwent percutaneous coronary intervention (PCI). In this study, 608 patients who underwent PCI for stable angina pectoris between January 2018 and December 2020 were included.

Predictive value of lipoprotein(a) for assessing the prevalence and severity of lower-extremity peripheral artery disease among patients with acute coronary syndrome.

Lipoprotein(a) [Lp(a)] is a reliable lipid marker for atherosclerosis. However, the clinical relevance of Lp(a) to lower-extremity peripheral artery disease (LE-PAD) and coronary artery disease (CAD) in the same patient has not been investigated. Patients who received primary percutaneous coronary intervention for the acute coronary syndrome (ACS) were enrolled.

Healed neointima of in-stent restenosis lesions in patients with stable angina pectoris: an intracoronary optical coherence tomography study.

The phenomenon to heal neointimal rupture or thrombus after coronary stenting occurs as well as in native coronary artery. We investigated clinical characteristics and neointimal vulnerability of healed neointima by optical coherence tomography (OCT). We treated 67 lesions by percutaneous coronary intervention for in-stent restenosis (ISR) and conducted OCT examinations.

Glasgow prognostic score can be a prognostic indicator after percutaneous coronary intervention: a two-center study in Japan.

Glasgow prognostic score (GPS) has been used to evaluate inflammatory response and nutritional status. This study aimed to investigate the impact of nutritional status on cardiac prognosis by using GPS in patients after undergoing percutaneous coronary intervention (PCI). We included 862 patients who underwent PCI for stable angina pectoris between 2015 and 2018.

Association between coronary artery calcium score on non-contrast chest computed tomography and all-cause mortality among patients with congestive heart failure.

Coronary artery calcium (CAC) score is a robust prognostic tool to predict cardiac events. Although patients with congestive heart failure (CHF) occasionally undergo non-contrast computed tomography (NCCT), the prognostic utility of CAC by NCCT is not widely known. We aimed to determine if CAC measured on NCCT is associated with all-cause mortality (ACM) among patients with CHF.

The relationship between coronary artery calcium density and optical coherence tomography-derived plaque characteristics.

Background And Aims: Although coronary artery calcium (CAC) density has been associated with plaque stability, pathological evidence is lacking. We investigated the relationship between coronary computed tomography (CCT)-derived CAC density and multiple calcified and high-risk plaque (HRP) characteristics using optical coherence tomography (OCT).

Methods: We analyzed 83 plaques from 33 stable angina patients who underwent both CCT and OCT.

Heart Rate After Resuscitation From Out-of-Hospital Cardiac Arrest due to Acute Coronary Syndrome Is an Independent Predictor of Clinical Outcome.

Background: Heart rate (HR) is a useful predictor of cardiovascular disease, especially in acute coronary syndrome (ACS). However, it is unclear whether there is an association between HR and clinical outcomes after resuscitation from out-of-hospital cardiac arrest (OHCA) due to ACS. The aim of this study was to investigate the impact of HR on clinical outcome in individuals resuscitated from OHCA due to ACS.

Loss of autophagy impairs physiological steatosis by accumulation of NCoR1.

Lipid droplets (LDs) are dynamic organelles that store neutral lipids during times of energy excess, such as after a meal. LDs serve as an energy reservoir during fasting and have a buffering capacity that prevents lipotoxicity. Autophagy and the autophagic machinery have been proposed to play a role in LD biogenesis, but the underlying molecular mechanism remains unclear.

Frailty and coronary plaque characteristics on optical coherence tomography.

The relationship between frailty and plaque characteristics is unclear and was investigated by optical coherence tomography (OCT) in this study. One hundred and four patients undergoing OCT before percutaneous coronary intervention were evaluated. Frailty was defined as a clinical frailty scale score of ≧6.

The impact of percutaneous coronary intervention using the novel dynamic coronary roadmap system.

The dynamic coronary roadmap (DCR) is a novel technology that creates a dynamic, motion-compensated, real-time overlay of the coronary arteries on a fluoroscopic image. Whether the DCR reduces contrast volume and enables safe and effective treatment was examined. A total of 146 patients undergoing percutaneous coronary intervention (PCI) from June 2017 to September 2017 in our hospital were retrospectively evaluated.
