Use of ADAM-C and CHA2DS2-VASc scores to predict complex aortic atheroma after brain ischemia: A prospective observational study.

BACKGROUND AND AIMS: Complex aortic atheroma (CAA) is a common cause of acute brain ischemia (BI), including ischemic stroke (IS) and transient ischemic attack (TIA), and is associated with recurrence. The CHA2DS2-VASc score is a useful tool for predicting stroke in patients with atrial fibrillation (AF), and can also predict cardiovascular events in other populations, including non-AF populations. The ADAM-C score is a new risk score for predicting the diagnostic yield of transesophageal echocardiography (TEE) after BI. We aimed to evaluate the ability of CHA2DS2-VASc and ADAM-C scores to predict CAA after BI. METHODS: This prospective, multicenter, observational study included 1479 patients aged over 18 years who were hospitalized for BI. CAA was defined as the presence of one or more of the following criteria: thrombus, ulcerated plaque, or plaque thickening ≥ 4 mm. RESULTS: CAA was diagnosed in 216 patients (14.6%). CHA2DS2-VASc and ADAM-C scores were significantly higher in the CAA group versus the non-CAA group (P < .0001 for both). The CHA2DS2-VASc and ADAM-C scores appear to be good predictors of CAA (AUC 0.699 [0.635, 0.761] and 0.759 [0.702, 0.814], respectively). The sensitivity, specificity, predictive positive value (PPV), and negative predictive value (NPV) of the scores for detecting CAA were 94%, 22%, 17%, and 96%, respectively, for a CHA2DS2-VASc score < 2, and 90%, 46%, 22%, and 96%, respectively, for an ADAM-C score < 3 CONCLUSIONS: CHA2DS2-VASc and ADAM-C scores are able to predict CAA after BI. CHA2DS2-VASc < 2 and ADAM-C < 3 both have an interesting NPV of 96%.

Perivalvular Mitral Abscess Fistulised to the Pericardial Cavity Revealing Staphylococcal Endocarditis.

BACKGROUND: Fistula to the pericardial cavity is a very rare complication of perivalvular abscess during infective endocarditis, with Staphylococcus aureus being the most commonly associated microorganism. METHODS: We report a fatal septic shock due to a mitral endocarditis revealed by a myocardial abscess fistulised toward the pericardial cavity. RESULTS: A 66-year-old female without previous valvular disease was admitted to intensive care for severe sepsis. A few hours after admission, an unexpected cardiac arrest occurred. Chest computed tomographic-scan and transoesophageal echocardiography revealed a pericardial effusion due to a perivalvular mitral abscess fistulised toward the pericardial cavity. Despite prompt management including surgical debridement and appropriate antibiotics, death occurred 36hours after intensive care admission. All blood cultures as well as native mitral valve and pericardial fluid grew methicillin-sensitive Staphylococcus aureus. CONCLUSIONS: Intensivists should consider this rare complication in patients with staphylococcal infective endocarditis and perivalvular abscess.

Effects of noradrenalin and albumin in patients with type I hepatorenal syndrome: a pilot study.

Treatment of hepatorenal syndromes (HRSs) is currently based on vasopressin analogs. The aim of this pilot study was to evaluate the efficacy and safety of noradrenalin (NA) in the treatment of type 1 HRS. Between 1998 and 2000, 12 consecutive patients with type 1 HRS (7 men, 5 women; mean age, 54 +/- 11 years; mean Child-Pugh score, 11.3 +/- 1.7) were treated with intravenous NA (0.5-3 mg/h), in combination with intravenous albumin and furosemide. NA was given for 10 +/- 3 days, at a mean dose of 0.8 +/- 0.3 mg/h. Reversal of HRS was observed in 10 of 12 patients (83%; 95% confidence interval, 52%-98%) after a median of 7 days (range, 5-10 days). Serum creatinine levels fell from 358 +/- 161 to 145 +/- 78 micromol/L (P <.001), creatinine clearance rose from 13 +/- 9 to 40 +/- 15 mL/min (P =.003), and urinary sodium output increased from 8 +/- 14 to 52 +/- 72 mEq/d (P =.002). Changes in renal function under NA treatment were associated with an increase in mean arterial pressure (MAP; 65 +/- 7 to 73 +/- 9 mm Hg, P =.01) and a marked reduction in active renin (565 +/- 989 to 164 +/- 196 ng/L, P =.001) and aldosterone plasma concentrations (1,945 +/- 1,931 to 924 +/- 730 ng/mL, P =.02). There was one episode of reversible myocardial hypokinesia (in a patient on 1.5 mg/h NA) that did not recur after a dose reduction. In conclusion, NA combined with albumin and furosemide appears effective and safe for the treatment of type 1 HRS.
