Background Stable coronary artery disease (CAD) is known to have an increased risk of cardiovascular events. Serum albumin (Alb) is reported as a useful risk-stratification tool in cardiovascular diseases such as acute coronary syndrome or heart failure. However, the association between Alb and stable CAD is unclear. Thus, we aimed to investigate the prognostic significance of Alb in patients with stable CAD. Methods and results We analyzed the data of all patients admitted to Shinonoi General Hospital between October 2014 and October 2017 for newly diagnosed stable CAD, treated via elective percutaneous coronary intervention, with the exception of old myocardial infarction. We collected data, including Alb, at admission. The primary endpoint was major adverse cardiac events (MACE; defined as all-cause death, non-fatal myocardial infarction, non-fatal stroke). In 204 enrolled patients (median age, 73 years), during a median follow-up of 783 days, 28 experienced MACE. Alb was significantly lower in patients with MACE than in those without (p<0.001). In Kaplan-Meier analysis, low Alb predicted worse prognosis in MACE (p<0.001). In multivariate Cox regression analysis, low Alb levels independently predicted MACE (p<0.001) after adjusting for age and sex (HR 4.128 [95% CI 1.632–10.440], p = 0.003), or, age and C-reactive protein (HR 3.373 [95% CI 1.289–8.828], p = 0.013). Conclusions Low Alb levels predicted MACE in patients with stable CAD.

The admission shock index (SI) enables prediction of short-term prognosis. This study investigated the prognostic implications of admission SI for predicting long-term prognoses for acute myocardial infarction (AMI). The participants were 680 patients with AMI who received percutaneous coronary intervention. Shock index is the ratio of heart rate and systolic blood pressure. Patients were classified as admission SI <0.66 (normal) and ≥0.66 (elevated; 75th percentile). The end point was 5-year major adverse cardiac events (MACEs). Elevated admission SI was seen in 176 patients. Peak creatine kinase levels were significantly higher and left ventricular ejection fraction was lower in the elevated SI group, which had a worse MACEs. In multivariate Cox regression analysis, SI ≥0.66 was a risk factor for MACE. Elevated admission SI was associated with poorer long-term prognosis.

The simple and practical assessment of GNRI may be useful for predicting CV events in patients with Stage A/B HF.

Brachial-ankle pulse wave velocity (baPWV) is known as a significant predictor of cardiovascular events. However, the previous studies have not considered age, which can affect the baPWV value. We evaluated the predictive value of baPWV for cardiovascular events in various age groups. From January 2005 to December 2012, all patients admitted to our department with any cardiovascular disease and underwent ankle-brachial index (ABI) measurement were enrolled in the IMPACT-ABI registry. The primary endpoints included major adverse cardiovascular events (MACE; cardiovascular death, myocardial infarction, and stroke). Of the 3131 patients enrolled, 2554 were included in the analysis, whereas 577 were excluded due to missing baPWV data, ABI ≤0.9 and/or >1.4, and the previous endovascular therapy and/or surgical treatment for peripheral artery disease. Patients were divided according to age 30-59 years (n = 580), 60-69 years (n = 730), 70-79 years (n = 862), and ≥80 years (n = 330). The cumulative incidence of MACE through 5 year was significantly higher in the high baPWV group (>1644 cm/s) than in the low baPWV group (≤1644 cm/s; 8.7 vs. 4.6%; log-rank: p < 0.001). However, among the age groups, only the 30-59-year group showed a significant difference in MACE incidence between those with high and low baPWV (7.0 vs. 0.9%; log-rank: p = 0.001). In conclusion, the baPWV could serve as a useful marker to predict cardiovascular events, particularly among younger patients.
