Direct Stenting Versus Pre‐Dilation in ST‐Elevation Myocardial Infarction: A Systematic Review and Meta‐Analysis 下载免费PDF全文

Objectives
This study aimed at comparing direct stenting (DS) versus stenting with pre‐dilation (SP) in patients with ST‐elevation myocardial infarction (STEMI), using a systematic review and meta‐analysis of published evidence.Background
There is conflicting evidence whether stenting strategy impacts clinical outcomes in patients with STEMI.Methods
We searched EMBASE, MEDLINE, and CENTRAL, from inception to December 2014. The primary endpoint was mortality. Secondary endpoints included major adverse cardiac events (MACEs), ST‐segment resolution, and angiographic outcomes.Results
A total of 9,331 patients enrolled in 12 studies (3 randomized controlled trials, RCTs; 9 non‐randomized studies, NRSs) were included. DS was associated with lower mortality (OR 0.55; 95%CI: 0.33–0.94; P = 0.03) in NRSs, and overall (OR 0.56; 95%CI: 0.37–0.86; P = 0.008). Mortality was non‐significantly reduced in RCTs (OR 0.56; 95%CI: 0.26–1.23; P = 0.15). DS was also associated with lower MACE rate (OR 0.71; 95%CI 0.60–0.84; P < 0.0001) in NRSs, but not in RCTs (OR 0.99; 95%CI: 0.61–1.60; P = 0.96). ST‐segment resolution, no reflow, final thrombolysis in myocardial infarction (TIMI) flow and final TIMI myocardial perfusion or blush grade were significantly better with DS in NRSs, and non‐significantly better in RCTs.Conclusions
The available evidence suggests that DS in STEMI might be associated with better clinical and procedural outcomes, as compared with SP. However, the fact that RCTs account for the minority of available data and that most of the available studies poorly reflect current clinical practice, as well as the existence of publication bias, preclude drawing definitive conclusions.55.

The frequency of obesity is increasing worldwide. The relationship between obesity and mortality is known. Bariatric surgery is well established in the treatment of morbid obesity to reduce weight permanently. Bariatric procedures are effective and influencing associated comorbidities. Adjustable gastric banding is a popular and effective bariatric operation in Europe for more than 10 years. Classic complications of gastric banding are known, but here we describe one more example. In this study, we report the case of a patient with gastric banding who presented with syncope after a meal. 相似文献

Objectives
To describe the particular assessment and closure strategy that was followed in patients with left atrial appendages (LAA) with an early and severe bend.Background
The presence of a chicken‐wing morphology with an early and severe bend constitutes one of the most difficult anatomical settings for transcatheter LAA occlusion.Methods
Between November 2009 and December 2012, patients who presented chicken‐wing LAA with an early (<20 mm from the ostium) and severe bend (<180°) were identified and included in the analysis. A particular implanting strategy consisting of deploying the distal lobe of the device inside the chicken‐wing bend was used in all cases.Results
Among 42 patients who underwent LAA occlusion during the study period, 5 (12%) presented the pre‐specified anatomy. Following the mentioned implanting strategy, all patients underwent successful LAA occlusion using the Amplatzer Cardiac Plug (n = 2) and the Amplatzer Amulet (n = 3). Successful occlusion was achieved in all patients. None of them presented any procedural complication. Follow‐up transesophageal echocardiography at 3 months showed successful LAA sealing in all patients and no device embolization or thrombosis.Conclusions
According to our results, the pre‐specified closing implantation technique for chicken‐wing LAAs with an early and severe bend might be a valid strategy for this challenging anatomical setting. Further cases will be necessary to confirm the results. (J Interven Cardiol 2013;26:509‐514)59.

Heart rate variability (HRV) is usually measured in time or frequency domains. Beat-to-beat variability, which cannot be assessed by frequency-domain analysis, and can only be assessed globally by time-domain analysis, provides information concerning the nonlinear behavior of heart rate. This beat-to-beat variability can be displayed on Scatterplots, where each RR interval is plotted against the preceding RR interval. However, the relationship between Scatterplots and other measures of HRV is unknown. We studied the correlations between time-domain measures and scatterplot length, width, and area in 50 postinfarction patients. Scatterplot length and width were measured after printing. Scatterplot area was calculated from length and width, assimilating the plot to an ellipse. Long-term variability indexes (SDNN and SDANN) were strongly correlated with scatterplot length (r > 0.9, P < 0.0001), and short-term variability parameters (pNN50 and variability index) with scatterplot width (r > 0.9; P < 0.0001). Scatterplots are, therefore, a simple way of providing information concerning long- and short-term HRV. Furthermore, measurement of scatterplot width at different given RR intervals could be an approach to the evaluation of short-term HRV for different heart rates. This could provide a simple way of assessing cardiac parasympathetic modulation at different heart rates. 相似文献

Precursors of VF. Ventricular fibrillation is the final event in the majority of cases of sudden death. The ECG and clinical precursors of ventricular fibrillation are discussed in this article. Ventricular fibrillation usually appears as a consequence of a chain of events that leads to the appearance of this lethal arrhythmia. We review the markers of the vulnerable myocardium prone to ventricular fibrillation, the triggers and modulators that act on this vulnerable myocardium, and the event(s) that constitute the final step preceding this arrhythmia. The final step may be as unique as a sudden waterfall or present as a cascade of successive phenomena. 相似文献
