Objectives: The incidence of contrast-induced nephropathy (CIN) after coronary angiography and the prognostic value in patients with acute myocardial infarction remains to be determined. This study investigated the frequency, predictors of CIN, and the prognostic significance of CIN in acute myocardial infarction patients undergoing emergent coronary angiography.
Methods: This study included 132 consecutive acute myocardial infarction patients undergoing emergent coronary angiography within 24 hr after the onset between January 1999 and June 2001. The serum creatinine concentration was measured on admission and at 48 hr after contrast medium exposure. CIN was defined as an increase in serum creatinine from the baseline > or = 0.5 mg/dl or > or = 25% at 48 hr after emergent coronary angiography. The patient characteristics, and in-hospital and long-term mortality were compared between the CIN and non-CIN groups.
Results: CIN occurred in 15 patients (11.4%) after emergent coronary angiography. The predictor of CIN development was preexisting renal impairment (serum creatinine concentration > or = 1.2 mg/dl on presentation; 21.9% vs 8.0%, odds ratio 3.22, 95% confidence interval 1.07-9.74, p = 0.04). In-hospital mortality was significantly higher in the CIN group than in the non-CIN group (13.3% vs 1.7%; odds ratio 8.85, 95% confidence interval 1.15-68.2, p = 0.01). The long-term mortality (mean follow-up period of 40 months) was also higher in the CIN group (26.7% vs 8.6%; hazard ratio 3.91, 95% confidence interval 1.21-12.5, p = 0.02).
Conclusions: CIN was an independent predictor of both in-hospital and long-term mortality in acute myocardial infarction patients undergoing emergent coronary angiography. Preexisting renal insufficiency was associated with subsequent CIN.

Background: The High-STEACS (High-Sensitivity Troponin in the Evaluation of Patients With Acute Coronary Syndrome) pathway risk stratifies emergency department patients with possible acute coronary syndrome. This study aims to determine if the High-STEACS hs-cTnT (high-sensitivity cardiac troponin T) pathway can achieve the ≥99% negative predictive value (NPV) safety threshold for 30-day cardiac death or myocardial infarction (CDMI) in a multisite US cohort of patients with and without known coronary artery disease (CAD).
Methods: A secondary analysis of the STOP-CP (High-Sensitivity Cardiac Troponin T [Gen 5 STAT Assay] to Optimize Chest Pain Risk Stratification) cohort, which enrolled adult emergency department patients with possible acute coronary syndrome at 8 US sites (January 25, 2017-September 6, 2018).

The field of cardio-oncology has traditionally focused on the impact of cancer and its therapies on cardiovascular health. Mounting clinical and preclinical evidence, however, indicates that the reverse may also be true: cardiovascular disease can itself influence tumor growth and metastasis. Numerous epidemiological studies have reported that individuals with prevalent cardiovascular disease have an increased incidence of cancer.

Objective: Extracorporeal membrane oxygenation (ECMO) is a high-risk procedure with significant morbidity and mortality and there is an uncertain volume-outcome relationship, especially regarding long-term functional outcomes. The aim of this study was to examine the association between ECMO centre volume and long-term death and disability outcomes.

Background: Microvascular dysfunction (MVD) is a recognized sign of disease in heart failure progression. Intact blood vessels exhibit abnormal vasoreactivity in early stage, subsequently deteriorating to rarefaction and reduced perfusion. In managing heart failure with preserved ejection fraction (HFpEF), earlier diagnosis is key to improving management.
