Background: Fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) for chronic coronary syndromes (CCS) improves outcomes compared with angiography-guided PCI, however cardiac events still occur during long-term follow-up of FFR-negative patients. In the PREVENT study preventive PCI reduced cardiac-events in lesions which were FFR-negative (FFR > 0.80) and had intracoronary imaging defined vulnerable plaque.

We investigated the prognostic value of cardiac myosin-binding protein C (cMyC), a novel cardiospecific marker, both independently and in combination with N-terminal pro-B-type natriuretic peptide (NT-proBNP), for predicting 6-month all-cause mortality in patients without acute coronary syndrome (ACS) treated at medical (nonsurgical) cardiac intensive care units (CICUs). Admission levels of cMyC, high-sensitivity cardiac troponin T (hs-cTnT), and NT-proBNP were measured in 1032 consecutive patients (mean age; 70 years) without ACS hospitalized acutely in medical CICUs for the treatment of cardiovascular disease. Serum cMyC was closely correlated with hs-cTnT and moderately with NT-proBNP (r = 0.

Article Synopsis
  • The study aimed to explore how physical and chemical digestion factors correlate with nutrition markers like serum albumin, prealbumin, and vitamin B levels in 92 participants at Fujita Health University.
  • Key findings showed that while physical digestion measures (like chewing and swallowing ability) did not significantly impact serum nutrition markers, there was a notable link between oral antacid use and decreased prealbumin levels.
  • The study concluded that using oral antacids might lower serum prealbumin, suggesting an effect on protein synthesis in the body.

Background: Coronary computed tomography angiography (CTA) followed by computed tomography angiography-derived fractional flow reserve (FFR) is now commonly used for the management of chronic coronary syndrome (CCS). CTA-verified high-risk plaque (HRP) characteristics have also been reported to be associated with a greater likelihood of adverse cardiac events but have not been used for management decisions.

Objectives: The aim of this study was to evaluate clinical outcomes based on a combination of point-of-care computed tomography angiography-derived fractional flow reserve (POC-FFR) and the presence of HRP in CCS patients initially treated medically or with revascularization based on invasive coronary angiography findings.

Article Synopsis
  • A study was conducted to investigate the effectiveness of deep learning reconstruction (PIQE) versus conventional imaging techniques (FIRST) in assessing in-stent restenosis (ISR) in small coronary stents during CT angiography.
  • The analysis involved 166 stents in 85 patients, measuring factors like stent strut thickness and lumen diameter to determine ISR presence, where a stenosis of 50% or more was considered significant.
  • Results showed that PIQE outperformed FIRST in image quality and ISR detection accuracy, especially for stents under 3.0 mm, suggesting that PIQE could enhance diagnostic processes and potentially reduce the necessity for invasive coronary angiography in certain patients.

Objectives: Malnutrition is associated with an increased risk of hospital readmission for heart failure in patients with acute decompensated heart failure (ADHF). Therefore, evaluation of the nutritional status in patients with ADHF may be important. The geriatric nutritional risk index (GNRI), the controlling nutritional status (CONUT) score, and the prognostic nutritional index (PNI) are widely used objective indexes for evaluation of the nutritional status.

Aims: Little is known about whether resting left ventricular global longitudinal strain (GLS) impairment is associated with myocardial perfusion abnormalities evaluated using N-ammonia positron emission tomography ( N-NH -PET)-myocardial perfusion imaging (MPI). This study aimed to investigate the correlation between resting GLS and myocardial perfusion parameters in patients with a normal left ventricular ejection fraction (LVEF). We evaluated whether resting GLS can predict myocardial perfusion abnormalities in these patients.

Background: Omega-3 fatty acids have been proposed to be useful in the prevention of cardiac events. High-risk plaque (HRP) and plaque progression on serial coronary computed tomography angiography (CTA) have been suggested to be the predecessor of acute coronary syndrome (ACS). The purpose of this study was to investigate whether addition of omega-3 fatty acids to statin therapy for secondary prevention would lead to change in plaque characteristics detected by using serial CTA.

Article Synopsis
  • The study examines the role of D-dimer levels in predicting mortality for patients with two types of heart failure: preserved left ventricular ejection fraction (HFpEF) and reduced left ventricular ejection fraction (HFrEF).
  • Researchers analyzed data from 1,670 hospitalized patients, finding that high D-dimer levels, along with the GWTG-HF risk score and NT-proBNP, were linked to a higher risk of death within 12 months.
  • When D-dimer was combined with these other measures, it significantly enhanced mortality predictions, suggesting that D-dimer can be a useful marker for assessing patient risk in acute heart failure cases.

Background: The high F-fluorodeoxyglucose (FDG) uptake in sarcoidosis lesions reflects infiltration of inflammatory cells such as macrophages. An increased incidence of cancer in patients with sarcoidosis has been suggested, and some combination of the following mechanisms has been proposed: chronic inflammation, immune dysfunction, shared aetiologic agents, and genetic susceptibility to both cancer and autoimmune diseases.

Case Summary: A 73-year-old man was admitted to our hospital due to effort dyspnoea.

Aims: In the updated guidelines for cardiac sarcoidosis (CS) proposed by the Japanese Circulation Society (JCS), the definition of isolated CS (iCS) was established for the first time. This prompted us to examine the characteristics of patients with CS including iCS according to them by reviewing patients undergoing F-fluoro-2-deoxyglucose positron-emission tomography/computerized tomography (FDG-PET/CT), compared with those with CS determined by the conventional international criteria.

Methods And Results: From 2013 to 2019, 94 patients (61 ± 15 years, 50 female patients) with suspected CS underwent whole-body and cardiac FDG-PET/CT scanning.
