TCT-352 A Safety and Efficacy Comparison Between the LIVE Versus Surgical Left Ventricular Reconstruction Techniques for Ischemic Heart Failure

Objectives and Background: We evaluated the ability of 23 genetic variants to provide prognostic information in patients enrolled in the Genetic Substudy of the Surgical Treatment for Ischemic Heart Failure (STICH) trials. Methods: Patients assigned to STICH Hypothesis 1 were randomized to medical therapy with or without coronary artery bypass grafting (CABG). Those assigned to STICH Hypothesis 2 were randomized to CABG or CABG with left ventricular reconstruction. Results: In patients assigned to STICH Hypothesis 2 (n = 714), no genetic variant met the prespecified Bonferroni-adjusted threshold for statistical significance (p < 0.002); however, several variants met nominal prognostic significance: variants in the β2-adrenergic receptor gene (β2-AR Gln27Glu) and in the A1-adenosine receptor gene (A1-717 T/G) were associated with an increased risk of a subject dying or being hospitalized for a cardiac problem (p = 0.027 and 0.031, respectively). These relationships remained nominally significant even after multivariable adjustment for prognostic clinical variables. However, none of the 23 genetic variants influenced all-cause mortality or the combination of death or cardiovascular hospitalization in the STICH Hypothesis 1 population (n = 532) by either univariate or multivariable analysis. Conclusion: We were unable to identify the predictive genotypes in optimally treated patients in these two ischemic heart failure populations.

Patients and methods This retrospective study selected 37 consecutive patients (32 men, mean age 59 ± 10.5 years) who underwent surgical ventricular reconstruction with associated coronary grafting, and preoperative left ventricular (LV) ejection fraction < 30% (mean, 25 ± 4.6%). The mean New York Heart Association (NYHA) class before operation was 3.4 ± 1.3. The time-frame of the large anterior myocardial infarction was 5.8 ± 3.3 months. LV systolic function was assessed by echo-dobutamine: the wall motion score index at rest (WMSIr), WMSI and the extent of LV asynergy (A%) during low-dose dobutamine (ldd). In-hospital mortality was 13.5%. After one-year, the mean functional NYHA class was 2.2 ± 1.1, and at one-year the mortality was 6.25%. Results Logistic regression analysis and the Proportional Odds model showed that LV A% during ldd (OR 0.86, p = 0.0086) was an independent predictor for the one-year postoperative functional NYHA class. Conclusions The preoperative extent of left ventricular asynergy during echo-dobutamine can predict the expectation of functional NYHA class improvement in patients with a severe ischemic heart failure one-year following surgical ventricular reconstruction with associated coronary grafting.

AbstractThe evidence supporting surgical aneurysmectomy in ischemic heart failure is inconsistent. The aim of the study was to describe long-term effect of minimally invasive hybrid transcatheter and minithoracotomy left ventricular (LV) reconstruction in patients with ischemic cardiomyopathy. Twenty-three subjects with transmural anterior wall scarring, LV ejection fraction 15–45%, and New York Heart Association class ≥ II were intervened using Revivent TC anchoring system. LV end-systolic volume index was reduced from 73.2 ± 27 ml at baseline to 51.5 ± 22 ml after 6 months (p < 0.001), 49.9 ± 20 ml after 2 years (p < 0.001), and 56.1 ± 16 ml after 5 years (p = 0.047). NYHA class improved significantly at 5 years compared to baseline. Six-min walk test distance increased at 2 years compared to the 6-month visit. Hybrid LV reconstruction using the anchoring system provides significant and durable LV volume reduction during 5-year follow-up in preselected patients with ischemic heart failure.

Aims: Angiotensin-converting-enzyme inhibitors (ACE inhibitors) are a cornerstone of drug therapy after myocardial infarction (MI) and improve left ventricular function and survival. We aimed to elucidate the impact of early treatment with the ACE inhibitor ramipril on the hematopoietic response after MI, as well as on the chronic systemic and vascular inflammation. Methods and Results: In a mouse model of MI, induced by permanent ligation of the left anterior descending artery, immediate initiation of treatment with ramipril (10 mg/k/d via drinking water) reduced cardiac inflammation and the number of circulating inflammatory monocytes, whereas left ventricular function was not altered significantly, respectively. This effect was accompanied by enhanced retention of hematopoietic stem cells, Lin−Sca1−c-Kit+CD34+CD16/32+ granulocyte–macrophage progenitors (GMP) and Lin−Sca1−c-Kit+CD150−CD48− multipotent progenitors (MPP) in the bone marrow, with an upregulation of the niche factors Angiopoetin 1 and Kitl at 7 d post MI. Long-term ACE inhibition for 28 d limited vascular inflammation, particularly the infiltration of Ly6Chigh monocytes/macrophages, and reduced superoxide formation, resulting in improved endothelial function in mice with ischemic heart failure. Conclusion: ACE inhibition modulates the myeloid inflammatory response after MI due to the retention of myeloid precursor cells in their bone marrow reservoir. This results in a reduction in cardiac and vascular inflammation with improvement in survival after MI.
