While left ventricular ejection fraction (LVEF) may improve in some pts with ischemic cardiomyopathy (ICM) following percutaneous coronary intervention (PCI), there are limited data with respect to the frequency and clinical predictors of this finding in pts who are candidates for subsequent placement of an implantable defibrillator (ICD). We retrospectively identified 105 consecutive pts with an initial LVEF <35% who underwent PCI and had follow-up echocardiographic assessment at least one mo (median 5.2 mo) later. No pt had a history of syncope or sustained ventricular arrhythmias. The indication for PCI was ST-elevation myocardial infarction (STEMI) in 17 patients (16.2%), non-ST-elevation MI (NSTEMI) in 76 pts (72.4%), and angina in 12 pts (11.4%). Mean age was 65 ± 12 yrs and 76% of pts were male. Hypertension was present in 80% of pts, diabetes in 47%, renal insufficiency in 30%, prior MI in 58%, and prior PCI in 51%. Following PCI, 85% received beta blockers, and 78% received ACEI or ARBs. These variables were distributed equally between groups. Overall, mean LVEF improved significantly at follow-up (27.8 ± 6.8% vs 38.3% ± 14.7%, p<0.001). LVEF improved for all indications, though there was a trend toward greater improvement in pts with STEMI (table ). LVEF improved by > 5% in 76 pts (72%). In 60 pts (57%) LVEF improved to a value > 35%, including 14 pts with initial LVEF ≤ 25%. Multivariate analysis of variance with repeated measures demonstrated that the improvement in LVEF was independent of all other clinical variables (p< 0.001), none of which alone or jointly predicted improvement. These results suggest that significant improvement in LVEF can be expected in a majority of pts with ICM following PCI, irrespective of clinical indication, and cannot be predicted easily from standard clinical variables. Decisions regarding prophylactic ICD implantation should be deferred until after late reassessment of LVEF in most of these pts.

Abstract Background Percutaneous coronary intervention (PCI) presents a relevant alternative to coronary bypass surgery for the treatment of patients with complex coronary artery disease and high perioperative risk. By temporary implantation of a percutaneous ventricular assist devices (pVAD) interventionalists attempt to anticipate the hemodynamic risk of those high-risk patients in a so-called protected PCI. The Impella® system presents the currently most common device for protected PCI and could show hemodynamic stability in earlier trials. Methods This study is a retrospective, observational multi-center registry of ten hospitals in Germany. We included patients undergoing protected high-risk PCI with Impella® support. The primary endpoint was defined as major adverse cardiac events (MACE) during a 180-day follow-up and consisted of all-cause mortality, myocardial infarction (MI) and stroke. Results Six of the participating hospitals performed a follow-up. In total, 157 patients (80.3% male; mean age 71.8±10.8 years) were included in the present study. Prior to PCI, median left ventricular ejection fraction was 39.0% (25.0%-50.0%) and median SYNTAX-Score I was 33.0 (24.0–40.5). The 180-day follow-up was available for 149 patients (94.9%). Eight patients (5.1%) were lost to follow-up. During the follow-up period, 34 patients (22.8%) suffered from a MACE. A total of 27 patients (18.1%) died. Nine patients (6.0%) sustained a MI, while 4 patients (2.7%) had a stroke. Kaplan-Meier curves for primary endpoint Conclusions Patients undergoing protected high-risk PCI with Impella® support show a good 180-day clinical outcome regarding rates of MACE and mortality. However, a head-to-head comparison of Impella supported patients to protected PCI with other pVADs is pending.

Background. Apoptosis plays an important role in the myocardial injury after acute myocardial infarction and in the subsequent development of heart failure. Aim. To clarify serum kinetics of apoptotic markers TRAIL and sFas and their relation to left ventricular ejection fraction (LVEF) in patients with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI). Methods. In 101 patients with STEMI treated with pPCI, levels of TRAIL and sFas were measured in series of serum samples obtained during hospitalization and one month after STEMI. LVEF was assessed at admission and at one month. Major adverse cardiovascular events (MACE, i.e., death, re-MI, and hospitalization for heart failure and stroke) were analysed during a two-year followup. Results. Serum level of TRAIL significantly decreased one day after pPCI (50.5pg/mL) compared to admission (56.7pg/mL), subsequently increased on day 2 after pPCI (58.8pg/mL), and reached its highest level at one month (70.3pg/mL). TRAIL levels on days 1 and 2 showed a significant inverse correlation with troponin and a significant positive correlation with LVEF at baseline. Moreover, TRAIL correlated significantly with LVEF one month after STEMI (day 1: r=0.402, p<0.001; day 2: r=0.542, p<0.001). On the contrary, sFas level was significantly lowest at admission (5073pg/mL), increased one day after pPCI (6370pg/mL), and decreased on day 2 (5548pg/mL). Significantly highest sFas level was marked at one month (7024pg/mL). sFas failed to correlate with LVEF at baseline or at one month. Both TRAIL and sFas showed no ability to predict improvement of LVEF one month after STEMI or a 2-year MACE (represented by 3.29%). Conclusion. In STEMI treated with pPCI, TRAIL reaches its lowest serum concentration after reperfusion. Low TRAIL level is associated with worse LVEF in the acute phase of STEMI as well as one month after STEMI. Higher TRAIL level appears to be beneficial and thus TRAIL seems to represent a protective mediator of post-AMI injury.

Abstract Background Successful recanalisation of percutaneous coronary intervention for chronic total occlusion lesions has been associated with improved survival. Purpose This study aimed to assess the impact of successful percutaneous coronary intervention for chronic total occlusion lesions on the long-term outcome of patients with impaired and preserved left ventricular ejection fraction (LVEF). Methods The study sample consisted of 842 consecutive patients (928 chronic total occlusion lesions) undergoing percutaneous coronary intervention at our institution between October 2005 and December 2009. We divided them into 3 groups by the degree of LVEF: less than 40% (severely reduced LVEF, n=140), 40% to 59% (moderately reduced LVEF, n=470), and 60% and above (normal LVEF, n=232). We evaluated mortality during the 10-year follow-up period the basis of procedural success and failure. Results The overall procedural success rate was 89.1%. Median follow-up duration was 7.9 years. The 10-year cumulative incidences of cardiac death in each degree of LVEF are shown in the Figure. Conclusions Successful recanalisation for chronic total occlusion lesions in patients with impaired LVEF may be associated with reduced cardiac mortality.

Objectives. Incomplete ST-segment elevation resolution (STR) occasionally occurs despite successful revascularization of epicardial coronary artery after primary percutaneous coronary intervention (PPCI). The aim of this study was to evaluate the relationship between the degree of STR and the severity of microvascular dysfunction. Methods. A total of 73 consecutive patients with ST-segment elevation myocardial infarction (STEMI) who underwent successful PPCI were evaluated. Serial 12-lead electrocardiography was performed at baseline and at 90 minutes after PPCI. Microvascular dysfunction was assessed by index of microvascular resistance (IMR) immediately after PPCI. Results. Patients were classified into 2 groups: 50 patients with complete STR (STR ≥50%) and 23 patients with incomplete STR (STR <50%). The incomplete STR group had a higher IMR value and lower left ventricular ejection fraction (LVEF), compared with the complete STR group. The degree of STR was significantly correlated with IMR (r = −0.416, P=0.002) and LVEF (r = 0.300, P=0.011). These correlations were only observed in patients with left anterior descending artery (LAD) infarction but not observed in patients with non-LAD infarction. A cutoff IMR value was 27.3 for predicting incomplete STR after PPCI. Conclusion. Incomplete STR after PPCI in patients with STEMI reflects the presence of microvascular and left ventricular dysfunction, especially in patients with LAD infarction.
