Combined impact of elevated arterial stiffness and left ventricular filling pressure on outcomes after off-pump coronary artery bypass grafting.

ABSTRACT:

Background

Brachial-ankle pulse wave velocity (baPWV) and early diastolic transmitral flow velocity to mitral annular tissue velocity (E/e')-which are markers of arterial stiffness and left ventricular (LV) filling pressure, respectively-have been associated with morbidity and mortality. We investigated their combined impact on postoperative complications and long-term survival of patients undergoing off-pump coronary artery bypass grafting (OPCAB).

Methods

A cohort of 164 patients were divided into four groups: baPWV ≤ 19 m/s and E/e' ≤ 15 (reference), baPWV > 19 m/s and E/e' ≤ 15 (high-PWV-only), baPWV ≤ 19 m/s and E/e' > 15 (high-E/e'-only), and baPWV > 19 m/s and E/e' > 15 (high-PWV-and-E/e'). After inverse probability treatment weighting adjustment, each group was compared with the reference group to analyze the odds ratios of postoperative complications and the Kaplan-Meier survival curves, and to identify the group representing an independent prognostic predictor.

Results

The median age and follow-up duration were 69 years and 57.2 months, respectively. Both postoperative acute kidney injury (POAKI) and atrial fibrillation (POAF) were higher in the high-PWV-and-E/e' group (adjusted odds ratio (OR) = 89.5; 95% confidence interval (CI), 8.5-942.3; p < 0.001 and OR = 12.5; CI, 2.5-63.8; p = 0.002, respectively). Compared to the reference group, only the high-PWV-and-E/e' group showed significantly lower survival rate (91.0%; CI, 82.8-100% vs. 44.8%; CI, 21.2-94.6%) and a higher hazard for all-cause mortality after adjustment for covariates (hazard ratio = 6.1; p = 0.002).

Conclusion

Concurrent elevation in PWV and E/e' may independently affect not only the rates of POAKI and POAF but also long-term survival after OPCAB.

Project description:The aim of the study was to study the effect of arterial stiffness and multifocal atherosclerosis on the 10-year prognosis of patients after coronary artery bypass grafting. Methods. Patients with coronary artery disease (n = 274) who underwent coronary artery bypass grafting (CABG), in whom cardio-ankle vascular index (CAVI) was assessed using the VaSera VS-1000 device and the presence of peripheral atherosclerosis in Doppler ultrasound. Groups were distinguished with normal CAVI (<9.0, n = 163) and pathological CAVI (≥9.0, n = 111). To assess the prognosis, coronary and non-coronary death, myocardial infarction, acute cerebrovascular accident/transient ischemic attack, repeated CABG, percutaneous coronary intervention, carotid endarterectomy, peripheral arterial surgery, pacemaker implantation were analyzed. Results. During the observation period, mortality was 27.7%. A fatal outcome from all causes was in 37 (22.7%) patients in the group with normal CAVI and in 39 (35.14%) in the group with pathological CAVI (p = 0.023). Death from cardiac causes was more common in the group with CAVI ≥ 9.0—in 25 cases (22.52%) than in the group with CAVI < 9.0—in 19 (11.6%, p = 0.016). The combined endpoint in patients with pathological CAVI was detected in 66 (59.46%) cases, with normal CAVI values—in 76 (46.63%) cases (p = 0.03). The presence of diabetes mellitus, multifocal atherosclerosis (p = 0.004), pathological CAVI (p = 0.063), and male gender were independent predictors of death at 10-year follow-up after CABG. The presence of multifocal atherosclerosis and pathological CAVI during the preoperative examination of patients were independent predictors of the combined endpoint development. Findings. Patients with coronary artery disease with pathological CAVI before CABG were more likely to experience adverse events and death in the long-term follow-up than patients with normal CAVI. Further studies are needed to investigate the possibility of correcting pathological CAVI after CABG after secondary prevention and the possible impact of this correction on prognosis.

Project description:ObjectivesDoes the manipulation of the off-pump CABG (OPCAB) in patient with depressed left ventricular function is better than on-pump CABG (ONCAB) approach in in-hospital mortality and morbidities? Here we undertook a meta-analysis of the best evidence available on the comparison of primary and second clinical outcomes of the off-pump and on-pump CABG.DesignSystematic literature reviewer and meta-analysis.Data sourcesPubMed, EMBASE, Web of science and Cochrane Center Registry of Controlled Trials were searched the studies which comparing the use of the off-pump CABG(OPCAB) and on-pump CABG (ONCAB) for patients with LVD during January 1990.1 to January 2018.Eligibility criteriaAll observation studies and randomized controlled trials comparing on-pump and off-pump as main technique for multi-vessel coronary artery disease (defined as severe stenosis (>70%) in at least 2 major diseased coronary arteries) with left ventricular dysfunction(defined as ejection fraction (EF) 40% or less) were included.Data extraction and synthesisAuthors will screen and select the studies extract the following data, first author, year of publication, trial characters, study design, inclusion and exclusion criteria, graft type, clinical outcome, assess the risk of bias and heterogeneity. Study-specific estimates will pool through the modification of the Newcastle-Ottawa scale for the quality of study and while leave-one-out analysis will be used to detect the impact of individual studies on the robustness of outcomes.ResultsAmong the 987 screened articles, a total of 16 studies (32,354 patients) were included. A significant relationship between patient risk profile and benefits from OPCAB was found in terms of the 30-day mortality (odds ratio [OR], 0.84; 95% confidence interval [CI], 0.73-0.97; P = 0.02), stroke (OR, 0.69; 95% CI, 0.55-0.86; P = 0.00), myocardial infarction (MI) (OR, 0.71; 95% CI, 0.53-0.96; P = 0.02), renal failure (OR, 0.71; 95% CI, 0.55-0.93; P = 0.01), pulmonary complication (OR, 0.68; 95% CI, 0.52-0.90; P = 0.01), infection (OR, 0.67; 95% CI, 0.49-0.91; P = 0.00),postoperative transfusion (OR, 0.25; 95% CI, 0.08-0.84; P = 0.02) and reoperation for bleeding (OR, 0.56; 95% CI, 0.41-0.75; P = 0.00). There was no significant difference in atrial fibrillation (AF) (OR, 0.96;95%; CI, 0.78-1.41; P = 0.56) and neurological dysfunction (OR, 0.88; 95% CI, 0.49-1.57; P = 0.65).ConclusionsCompared with the on-pump CABG with LVD, using the off-pump CABG is a better choice for patients with lower mortality, stroke, MI, RF, pulmonary complication, infection, postoperative transfusion and reoperation for bleeding. Further randomized studies are warranted to corroborate these observational data.
