Background: The proportion of young females among the patients who undergo percutaneous coronary intervention (PCI) is relatively small, and information on their clinical characteristics is limited. This study investigated the clinical characteristics and prognostic factors for future cardiac events in young females who underwent PCI. Methods: This multicenter observational study included 187 consecutive female patients aged < 60 years who underwent PCI in seven hospitals. The primary composite endpoint was the incidence of cardiac death, nonfatal myocardial infarction, and target vessel revascularization. Results: The mean patient age was 52.1 ± 6.1 years and 89 (47.6%) had diabetes, and renal dysfunction (an estimated glomerular filtration rate < 60 mL/min/1.73 m2) was observed in 38 (20.3%). During a median follow-up of 3.3 years, the primary endpoint occurred in 28 patients. The Cox proportional hazards models showed that renal dysfunction was an independent predictor for the primary endpoint (hazard ratio 3.04, 95% confidence interval 1.25–7.40, p = 0.01), as well as multivessel disease (hazard ratio 2.79, 95% confidence interval 1.12–6.93, p = 0.03). Patients with renal dysfunction had a significantly higher risk for the primary endpoint than those without renal dysfunction. Conclusions: Renal dysfunction was strongly associated with future cardiac events in young females who underwent PCI. [ABSTRACT FROM AUTHOR]

Despite the excellent long-term results of internal mammary artery (IMA)–left anterior descending (LAD) bypass, percutaneous revascularization of IMA is sometimes required for IMA-LAD bypass failure. However, its clinical outcomes have not been fully elucidated. The aim of this study was to investigate the long-term clinical outcomes, including target lesion revascularization (TLR) following contemporary percutaneous revascularization of failed IMA bypass graft. We examined data of 59 patients who had undergone percutaneous revascularization of IMA due to IMA-LAD bypass failure at nine hospitals. Patients with IMA graft used for Y-composite graft or sequential bypass graft were excluded. The incidence of TLR was primarily examined, whereas other clinical outcomes including cardiac death, myocardial infarction, and target vessel revascularization were also evaluated. Mean age of the enrolled patients was 67.4 ± 11.3 years, and 74.6% were men. Forty patients (67.8%) had anastomotic lesions, and 17 (28.8%) underwent revascularization within three months after bypass surgery. Procedural success was achieved in 55 (93.2%) patients. Stent implantation was performed in 13 patients (22.0%). During a median follow-up of 1401 days (interquartile range, 282–2521 days), TLR was required in six patients (8.5% at 1, 3, and 5 years). Patients who underwent percutaneous revascularization within 3 months after surgery tended to have a higher incidence of TLR. Clinical outcomes of IMA revascularization for IMA-LAD bypass failure were acceptable. [ABSTRACT FROM AUTHOR]

The HATCH score is employed as a risk assessment tool for atrial fibrillation (AF) development. However, the impact of the HATCH score on the long-term adverse outcomes in patients with acute heart failure (AHF) remains unknown. We investigated the clinical value of the HATCH score in patients with AHF. From a multicenter AHF registry, we retrospectively evaluated 1543 consecutive patients who required hospitalization owing to AHF (median age, 78 [69–85] years; 42.3% women) from January 2012 to December 2019. These patients were divided into five risk groups based on their HATCH score at admission (scores 0, 1, 2, 3, and 4–7). The correlation between the HATCH score and the composite outcome, including all-cause mortality and re-hospitalization due to HF, was analyzed using Kaplan–Meier and Cox proportional-hazard analyses. The median HATCH score was 2 [1–3], and the median age was 78 years (69–85 years). During the follow-up period (median, 16.8 months), the composite endpoint occurred in 691 patients (44.8%), including 416 (27%) patients who died (with 65 [4.2%] in-hospitalization deaths) and 455 (29.5%) patients requiring re-hospitalizations due to HF. The Kaplan–Meier analysis showed a significant increase in the composite endpoint with an increasing HATCH score (log-rank, p < 0.001). The multivariate Cox regression model revealed that the HATCH score was an independent predictor of the composite endpoint (hazard ratio [HR] 1.181; 95% confidence interval [CI]: 1.111–1.255; p < 0.001) with all-cause mortality (HR 1.153, 95% CI 1.065–1.249; p < 0.001) and re-hospitalizations due to HF (HR 1.21; 95% CI 1.124–1.303; p < 0.001) in patients with AHF, regardless of the presence or absence of AF, ejection fraction, and etiology. The HATCH score is an independent predictor of adverse outcomes in patients with AHF. [ABSTRACT FROM AUTHOR]

The aim of the present study was to evaluate the renal outcomes, including the time course of renal function, after elective PCI in patients with advanced renal dysfunction and to assess the predictors of renal dysfunction progression. This is a subanalysis of a previous observational multicenter study that investigated long-term clinical outcomes in patients with advanced renal dysfunction (eGFR < 30 mL/min/1.73 m2), focusing on 151 patients who underwent elective PCI and their long-term renal outcomes. Renal dysfunction progression was defined as a 20% relative decrease in eGFR at 1 year from baseline or the initiation of permanent dialysis within 1 year. Progression of renal dysfunction at 1 year occurred in 42 patients (34.1%). Among patients with renal dysfunction progression, the decrease of renal function from baseline was not observed at 1 month but after 6 months of the index PCI. Baseline eGFR and serum albumin level were significant predictors of renal dysfunction progression at 1 year. Among 111 patients who had not been initiated on dialysis within 1 year, those with renal dysfunction progression had a significantly higher incidence of dialysis initiation more than 1 year after the index PCI than those with preserved renal function (p < 0.001). Among patients with advanced renal dysfunction who underwent elective PCI, 34.1% showed renal dysfunction progression at 1 year. The decrease in renal function was not observed at 1 month but after 6 months of the index PCI in patients with renal dysfunction progression. Furthermore, patients with renal dysfunction progression had poorer long-term renal outcomes. [ABSTRACT FROM AUTHOR]
