- Previous models for contrast-induced acute kidney injury (CI-AKI) after percutaneous coronary intervention (PCI) include procedure-related variables in addition to pre-procedural variables. We sought to develop a risk model for CI-AKI based on pre-procedural variables and compare its predictability with a conventional risk model and also to develop an integer score system based on selected variables. A total of 5,936 consecutive PCIs registered in the Japanese Cardiovascular Database were analyzed (derivation cohort, n = 3,957; validation cohort, n = 1,979).
- Plasma amino acid concentrations (aminogram) show distinct patterns under various pathologic conditions. However, the plasma aminogram pattern in patients with pulmonary hypertension (PH) has not been elucidated. We sought to examine whether an aminogram could be predictive of clinical severity in patients with PH. We attained fasting plasma aminograms for 140 patients with PH and then compared the patient plasma amino acid levels with those of age- and gender-matched healthy control subjects. Aminograms revealed that the plasma concentrations of many amino acids were significantly different between patients with PH and healthy control subjects.
- Understanding the perspective of early-career cardiologists is important to design effective responses to the challenges in modern cardiovascular (CV) training programs. We conducted a web-based survey on a total of 272 early-career cardiologists (within 10 postgraduate years) who registered for the 2011 annual Japanese Circulation Society Meeting. Main outcome measures were satisfaction with their training, confidence in their clinical skills, and professional expectations, scaled from 0 to 10.
