Article Synopsis
  • The Naples prognostic score (NPS) is a new system designed to assess inflammation and nutrition in cancer patients, but its effectiveness in chronic kidney disease (CKD) patients after percutaneous coronary intervention (PCI) is still being studied.
  • A research study included 631 CKD patients who received PCI from 2019 to 2022, splitting them into low-risk and high-risk groups based on their NPS, with follow-ups conducted until November 2022 to measure Major Adverse Cardiac Events (MACE).
  • Results indicated that the NPS is better at predicting MACE than other assessment scores, and the high-risk group experienced more adverse events and had worse prognoses compared to the low-risk group.

Article Synopsis
  • - The study investigates the relationship between the high-sensitivity C-reactive protein to high-density lipoprotein cholesterol (hsCRP/HDL-C) ratio (CHR) and long-term health outcomes in patients with coronary artery disease (CAD) after undergoing percutaneous coronary intervention (PCI).
  • - Researchers categorized 3,260 CAD patients who had PCI into three groups based on their CHR levels and found that higher CHR was linked with increased risks of all-cause mortality, cardiac mortality, and major adverse cardiac events.
  • - The analysis indicated that patients in the highest CHR group faced significantly higher risks (2.127 times for all-cause mortality and 3.575 times for cardiac mortality) compared to those

Currently, the standard treatment for patients who have undergone percutaneous coronary intervention (PCI) following acute myocardial infarction (MI) involves dual antiplatelet therapy (DAPT) with a combination of aspirin and a potent P2Y12 receptor inhibitor. However, the potential benefits of aspirin were partially constrained by the intolerance of some patients. The safety and efficacy of indobufen, an alternative antiplatelet agents to aspirin, in patients with AMI after PCI are yet to be thoroughly investigated.

A growing body of evidence on a wide spectrum of adverse cardiac events following oncologic therapies has led to the emergence of cardio-oncology as an increasingly relevant interdisciplinary specialty. This also calls for better risk-stratification for patients undergoing cancer treatment. Machine learning (ML), a popular branch discipline of artificial intelligence that tackles complex big data problems by identifying interaction patterns among variables, has seen increasing usage in cardio-oncology studies for risk stratification.

Chest pain, a common initial symptom in hypertrophic cardiomyopathy (HCM) patients, is closely linked to myocardial ischemia, despite the absence of significant coronary artery stenosis. This study explored microvascular dysfunction in HCM patients by employing angiography-derived microcirculatory resistance (AMR) as a novel tool for comprehensive assessment. This retrospective analysis included HCM patients with chest pain as the primary symptom and control patients without cardiac hypertrophy during the same period.

Article Synopsis
  • This study evaluated the prevalence and impact of newly diagnosed diabetes on elderly patients (≥65 years) undergoing percutaneous coronary intervention (PCI) from 2004 to 2021, where 2456 patients were followed for an average of five years.
  • It found that newly diagnosed diabetes affected 8.1% to 10.9% of these patients, significantly increasing their risk for major adverse cardiovascular events (MACE) compared to those with previously identified diabetes (25.28% vs. 19.15%).
  • The research concluded that newly diagnosed diabetes is an independent predictor of increased risks for MACE, cardiac death, and repeat revascularization, highlighting the need for greater attention to this group of elderly patients post

Article Synopsis
  • Chronic renal failure (CRF) patients are at higher risk for ventricular arrhythmias and sudden cardiac death, potentially due to chronic inflammation affecting heart nerve structures.
  • A study on rats showed that CRF led to increased markers of inflammation and nerve remodeling, as well as alterations in heart structure and function.
  • Treatment with atorvastatin and etanercept effectively reduced these negative changes, suggesting they may help manage cardiac complications in CRF patients.

Inflammation contributes to the pathophysiological processes of coronary artery disease. We evaluated the association between inflammatory biomarkers, neutrophil-to-lymphocyte ratio (NLR), red cell distribution width (RDW), systemic inflammatory index, platelet-lymphocyte ratio, and 1-year all-cause mortality in patients underwent percutaneous coronary intervention (PCI). In this retrospective cohort, we consecutively enrolled 4651 patients who underwent PCI.

Background: Previous studies reported that compared to conventional dual antiplatelet therapy (DAT; aspirin + clopidogrel), triple antiplatelet therapy (TAT), involving the addition of cilostazol to DAT, had better clinical outcomes in patients with ST-elevation myocardial infarction (STEMI). However, the optimal duration of TAT is yet to be determined.

Methods: In total, 985 patients with STEMI who underwent primary percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) were prospectively enrolled in 15 PCI centers in South Korea and China.

Patients with complex coronary lesions undergoing percutaneous coronary intervention (PCI) have more major adverse cardiac events (MACE) than do those with simpler cases. Therefore, intensive antiplatelet therapy might be needed in these patients. A total of 127 patients with complex lesions undergoing PCI in the Second Hospital of Tianjin Medical University from October 2012 to April 2014 were randomized to receive either dual (aspirin plus clopidogrel, DAPT, n = 66), or triple antiplatelet therapy (aspirin plus clopidogrel plus cilostazol; TAPT, n = 61).
