Myocardial contrast echocardiography is superior to other known modalities for assessing myocardial reperfusion after acute myocardial infarction
Background: Angiographic flow measurements do not define perfusion accurately at a microvascular level, so other techniques which assess flow at a tissue level are to be preferred. Objectives: To compare intravenous myocardial contrast echocardiography (MCE) with other methods of assessing microvascular reperfusion for their ability to predict left ventricular function at one month after acute myocardial infarction. Design: 15 patients underwent primary percutaneous coronary angioplasty for acute myocardial infarction, with restoration of TIMI grade 3 flow. Corrected TIMI frame count (cTFC), myocardial blush grade (MBG), and percentage ST segment resolution at 90 and 180 minutes were recorded. Baseline regional wall motion score index (WMSI) and regional contrast score index (RCSI) were obtained 12–24 hours after the procedure, with a final regional WMSI assessment at one month. Results: Mean (SD) cTFC was 27 (9.4), and ST segment resolution was 69 (22)% at 90 minutes and 77 (20)% at 180 minutes. MBG values were 0 in six patients, 2 in two, and 3 in seven. Baseline regional WMSI, RCSI, and follow up WMSI were 2.7 (0.71), 1.5 (0.71), and 1.6 (0.73), respectively. The correlation coefficient between RCSI and follow up WMSI was 0.82 (p = 0.0012). Peak CK correlated with follow up WMSI (R = 0.80). None of the other reperfusion assessment techniques correlated significantly with follow up WMSI. Multiple regression analysis showed that a perfused hypokinetic or akinetic segment was 50 times more likely to recover function than a non-perfused segment. MCE predicted segmental myocardial recovery with a sensitivity of 88%, a specificity of 74%, and positive and negative predictive values of 83% and 81%, respectively. Conclusions: MCE is currently the best and most accurate measure of reperfusion at a microvascular level and an excellent predictor of left ventricular function at one month following acute myocardial infarction
Influence of isoprostane F-2 alpha-III on reflow after myocardial infarction
Aims: To investigate whether the vasoconstrictor isoprostane F 2?-III (iPF2?-III), released during myocardial reperfusion, contributes to the low/no reflow phenomenon observed following acute myocardial infarction (AMI). Methods and results: Thirteen patients undergoing primary percutaneous coronary intervention (PCI) for AMI had iPF2?-III measured by high-performance liquid and gas chromatography-mass spectrometry. Isoprostane F2?-III concentrations were significantly higher following PCI than in controls (1.5 ± 1.3 vs. 16 ± 0.06 nM, p < 0.001). Mean iPF 2?-III concentration correlated positively with ST-segment resolution at 90 min (R = 0.62, p < 0.05). In the isolated murine heart: (a) coronary vasoconstriction occurred at, or above, iPF2?-III concentrations of 1 ?M. From 1 to 10 ?M, iPF2?-III induced dose-dependent vasoconstriction (p = 0.005) with reduction in coronary flows (CF) of 57 ± 5% and 31 ± 4% (percentage baseline), respectively; (b) SQ29548 1 ?M completely reversed the vasoconstrictive effects of iPF2?-III 10 ?M; (c) SQ29548 1 ?M infused during reperfusion following 30 min ischaemia had no effect on CF or infarct volume. Conclusion: Concentrations of iPF2?-III released into the venous circulation during reperfusion following AMI in humans are significantly lower than those required to diminish coronary flow in the murine heart; increased levels indicate successful reperfusion. Inhibition of iPF 2?-III has no effect on coronary flow or infarct size in the murine heart, suggesting that iPF2?-III alone does not account for the low/no reflow phenomenon observed following AMI. © 2004 The European Society of Cardiology.

GOSAFE - Geriatric Oncology Surgical Assessment and Functional rEcovery after Surgery: early analysis on 977 patients
Objective: Older patients with cancer value functional outcomes as much as survival, but surgical studies lack functional recovery (FR) data. The value of a standardized frailty assessment has been confirmed, yet it's infrequently utilized due to time restrictions into everyday practice. The multicenter GOSAFE study was designed to (1) evaluate the trajectory of patients' quality of life (QoL) after cancer surgery (2) assess baseline frailty indicators in unselected patients (3) clarify the most relevant tools in predicting FR and clinical outcomes. This is a report of the study design and baseline patient evaluations. Materials & Methods: GOSAFE prospectively collected a baseline multidimensional evaluation before major elective surgery in patients (≥70 years) from 26 international units. Short−/mid−/long-term surgical outcomes were recorded with QoL and FR data. Results: 1003 patients were enrolled in a 26-month span. Complete baseline data were available for 977(97.4%). Median age was 78 years (range 70–94); 52.8% males. 968(99%) lived at home, 51.6% without caregiver. 54.4% had ≥ 3 medications, 5.9% none. Patients were dependent (ADL < 5) in 7.9% of the cases. Frailty was either detected by G8 ≤ 14(68.4%), fTRST ≥ 2(37.4%), TUG > 20 s (5.2%) or ASAIII-IV (48.8%). Major comorbidities (CACI > 6) were detected in 36%; 20.9% of patients had cognitive impairment according to Mini-Cog. Conclusion: The GOSAFE showed that frailty is frequent in older patients undergoing cancer surgery. QoL and FR, for the first time, are going to be primary outcomes of a real-life observational study. The crucial role of frailty assessment is going to be addressed in the ability to predict postoperative outcomes and to correlate with QoL and FR
