Patients At Risk

Abstract Background Patients with chronic total coronary occlusions (CTO) are at increased risk for poor clinical outcomes. We aimed to determine the incidence of CTO percutaneous coronary intervention (PCI) and to identify CTO patients at risk for cardiac events in the nationwide Netherlands Heart Registration (NHR). Methods We included all PCI procedures with ≥1 CTO registered in the NHR from January 2015 to December 2018, excluding acute interventions. We used multivariable logistic regression of baseline characteristics to calculate the risk for events as odds ratios (OR) with 95% confidence intervals (CI). Results Of the PCIs performed during the study period, 6.3% (8,343/133,042) were for CTOs, with the percentage increasing significantly over time from 5.9% in 2015 to 6.6% in 2018 (p < 0.001). Coronary artery bypass grafting <24 h was carried out in 0.3%, and the only significant predictor was diabetes mellitus (OR 2.97, 95% CI 1.04–8.49, p = 0.042). Myocardial infarction (MI) <30 days occurred in 0.5%, and renal insufficiency (i.e. estimated glomerular filtration rate <30 ml/min per 1.73 m2) was identified as an independent predictor (OR 4.70, 95% CI 1.07–20.61, p = 0.040). Among patients undergoing CTO-PCI, 1‑year mortality was 3.7%, and independent predictors included renal insufficiency (OR 5.59, 95% CI 3.25–9.59, p < 0.001), left ventricular ejection fraction <30% (OR 3.43, 95% CI 2.00–5.90, p < 0.001), previous MI (OR 1.62, 95% CI 1.14–2.31, p = 0.007) and age (OR 1.06 per year increment, 95% CI 1.04–1.07, p < 0.001). Target-vessel revascularisation <1 year occurred in 11.3%. Conclusion CTO-PCI is still infrequently performed in the Netherlands. The most important predictor of mortality after CTO-PCI was renal insufficiency. Identification of patients at risk may help improve the prognosis of CTO patients in the future.

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.

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.
