Abstract Importance: Abnormal left ventricular (LV) diastolic function, with or without a diagnosis of heart failure, is a common finding that can be easily diagnosed by intra-operative transesophageal echocardiography (TEE). The association of diastolic function with duration of hospital stay after coronary artery bypass (CAB) is unknown. Objective: To determine if abnormal LV diastolic function (diastolic dysfunction) is associated with length of hospital stay after coronary artery bypass surgery (CAB). Design: Prospective observational studySetting: A single tertiary academic medical centerParticipants: Patients with normal systolic function undergoing isolated CAB from September 2017 through June 2018. Exposures: LV function during diastole, as assessed by intra-operative TEE prior to coronary revascularization. Main Outcomes and Measures: The primary outcome was duration of postoperative hospital stay. Secondary intermediate outcomes included common postoperative cardiac, respiratory, and renal complications. Results: The study included 176 participants (mean age 65.2 +/- 9.2 years, 73% male); 106 (60.2%) had LV diastolic dysfunction. Median time to hospital discharge was significantly longer for subjects with diastolic dysfunction (9.1/IQR 6.6-13.5 days) than those with normal LV diastolic function (6.5/IAR 5.3-9.7days) (P< 0.001). The probability of hospital discharge was 34% lower (HR 0.66/95% CI 0.47-0.93) for subjects with diastole dysfunction, independent of potential confounders, including a baseline diagnosis of heart failure. There was a dose-response relation between severity of diastolic dysfunction and probability of discharge. LV diastolic dysfunction was also associated with postoperative cardio-respiratory complications; however, these complications did not fully account for the relation between LV diastolic dysfunction and prolonged length of hospital stay.Conclusions and Relevance: In patients with normal systolic function undergoing CAB, diastolic dysfunction is associated with prolonged duration of postoperative hospital stay. This association cannot be explained by baseline comorbidities or common post-operative complications.

Background: Abnormal left ventricular (LV) echocardiographic parameters during non-systolic phase, with or without a diagnosis of heart failure, is a common finding that can be easily diagnosed by intra-operative transesophageal echocardiography (TEE). However, its association with duration of hospital stay after coronary artery bypass (CAB) is unknown. Objective: To determine if Abnormal left ventricular (LV) echocardiographic parameters during non-systolic phase is associated with length of hospital stay after coronary artery bypass surgery (CAB). Method: Prospective observational study at a single tertiary academic medical center Result: Median time to hospital discharge was significantly longer for subjects with abnormal left ventricular (LV) echocardiographic parameters during non-systolic phase (9.1/IQR 6.6-13.5 days) than those with normal LV non-systolic function (6.5/IAR 5.3-9.7days) (P< 0.001). The probability of hospital discharge was 34% lower (HR 0.66/95% CI 0.47-0.93) for subjects with abnormal LV function even during non-systole despite a normal LV systolic function, independent of potential confounders, including a baseline diagnosis of heart failure Conclusions and Relevance: In patients with normal systolic function undergoing CAB, non-systolic LV dysfunction is associated with prolonged duration of postoperative hospital stay.

Management of patients with peripartum cardiomyopathy (PPCM) is still a major clinical problem, as only half of them or slightly more show complete recovery of left ventricular (LV) function despite conventional evidence-based treatment for heart failure. Recent observations suggested that bromocriptine might favor recovery of LV systolic function in patients with PPCM. However, no evidence exists regarding its effect on LV diastolic dysfunction, which is commonly observed in these patients. Tissue Doppler (TD) is an echocardiographic technique that provides unique information on LV diastolic performance. We report the case of a 37-year-old white woman with heart failure (NYHA class II), moderate LV systolic dysfunction (ejection fraction 35%), and severe LV diastolic dysfunction secondary to PPCM, who showed no improvement after 2 weeks of treatment with ramipril, bisoprolol, and furosemide. At 6-week followup after addition of bromocriptine, despite persistence of LV systolic dysfunction, normalization of LV diastolic function was shown by TD, together with improvement in functional status (NYHA I). At 18-month followup, the improvement in LV diastolic function was maintained, and normalization of systolic function was observed. This paper might support the clinical utility of bromocriptine in patients with PPCM by suggesting a potential benefit on LV diastolic dysfunction.

Background: It is unclear whether atrial fibrillation (AF) catheter ablation (AFCA) improves the left ventricular (LV) diastolic function. We evaluated the 1-year change in the H2FPEF score, which reflects the degree of LV diastolic function, after AFCA among patients with a normal LV systolic function.Methods and Results: We included 1,471 patients (30.7% female, median age 60 years, paroxysmal-type AF 68.6%) who had available H2FPEF scores at baseline and at 1-year after AFCA to evaluate the 1-year change in the H2FPEF score (ΔH2FPEF score[1−yr]) after AFCA. Baseline high H2FPEF scores (≥6) were independently associated with the female sex, left atrium (LA) diameter, LV mass index, pericardial fat volume, and a low estimated glomerular filtration rate. One year after AFCA, decreased ΔH2FPEF scores[1−yr] were associated with baseline H2FPEF scores of ≥6 [OR, 4.19 (95% CI, 2.88–6.11), p &lt; 0.001], no diabetes [OR, 0.60 (95% CI, 0.37–0.98), p = 0.04], and lower pericardial fat volume [OR, 0.99 (95% CI, 0.99–1.00), p = 0.003]. Increased ΔH2FPEF scores[1−yr] were associated with a baseline H2FPEF score of &lt;6 [OR, 3.54 (95% CI, 2.08–6.04), p &lt; 0.001] and sustained AF after a recurrence within 1 year [SustainAF[1−yr]; OR, 1.89 (95% CI, 1.01–3.54), p = 0.048]. Throughout a 56-month median follow-up, an increased ΔH2FPEF score[1−yr] resulted in a poorer rhythm outcome of AFCA (at 1 year, log-rank p = 0.003; long-term, log-rank p = 0.010).Conclusions: AFCA appears to improve LV diastolic dysfunction. However, SustainAF[1−yr] may contribute to worsening LV diastolic dysfunction, and it was shown by increased ΔH2FPEF scores[1−yr], which was independently associated with higher risk of AF recurrence rate after AFCA.Clinical Trial Registration:ClinicalTrials.gov Identifier: NCT02138695.

Objective: Minimal invasive extracorporeal circuits (MiECC) have been associated with a significant reduction in the incidence of postoperative atrial fibrillation (AF). Nevertheless, AF remains one of the most common complications following elective primary coronary artery bypass grafting (CABG). The aim of this study was to identify the predictors of AF persisting beyond the hospital stay in elective primary CABG patients. Methods: We conducted a retrospective analysis for the predictors of AF that persisted beyond discharge between all patients who received an elective isolated CABG in our institution between 2009 and 2014. Patients with a positive history for intermittent or persistent AF were excluded from the analysis. Almost all patients were discharged to a rehabilitation facility where they stayed for 3 to 4 weeks postoperatively. At rehab approximately 91% of them received Holter monitoring at least once prior to their discharge. Results: A total of 770 patients were included in the analysis of which 763 patients survived the in-hospital stay. The incidence of AF at hospital discharge was 4.2% (32/763) while that on Holter monitor at Rehab was 1.5% (10/685). Age and the type of extracorporeal circuit (ECC) utilized were the only significant predictors for both AF at discharge ( p < 0.01 both) and on Holter monitor in rehab ( p < 0.01 and 0.02, respectively). This was also confirmed on multivariate analysis. Conclusion: Our findings show that the benefits of MiECC regarding the incidence of postoperative AF persist beyond hospital discharge. They may thus positively influence the outcomes of patients beyond the early postoperative period.

Abstract Background Pain that pursues coronary artery bypass graft (CABG) surgery is usually associated with increased both recovery duration and hospital stay. Patient outcome could be worsened owing to large doses of opioids for pain control through over sedation, and prolonged mechanical ventilation. This study was designed to evaluate the effect of preemptive gabapentinoids on post CABG surgery pain control. Objective to evaluate the effect of pre-operative administration of pregabalin and gabapentin in limiting the post-operative pain in coronary artery bypass surgeries. Patients and Methods Type of Study: Prospective double – blinded, randomized controlled Trial. After Approval is obtained from the research ethics committee of anesthesia and intensive care department, Ain Shams University. Study Setting: National Heart Institute, Egypt. Study Period: 6 months. Study Population: adult undergoing coronary artery bypass graft surgeries. Results The primary outcome of this study was to compare the effect of gabapentinoids on post CABG pain as reflected by morphine consumption. The secondary outcome was to address the influence of gabapentinoids on patient satisfaction post CABG, the incidence of respiratory depression, nausea, vomiting, ventilatory hours and length of hospital stay. Conclusion Pregabalin, and gabapentin both can be effective for reduction of post CABG morphine consumption and have better patient satisfaction if given preemptively with single dose preoperatively.

Introduction Although it is not a new technique, minimally invasive direct coronary artery bypass (MIDCAB) is employed only by a few surgeons in the UK. We compared our experience with MIDCAB with that of single vessel off-pump coronary artery bypass (OPCAB) graft surgery through a standard median sternotomy. Methods Patients who underwent either MIDCAB or OPCAB between April 2008 and July 2011 were reviewed. Exclusion criteria included patients with an ejection fraction of <0.5 or previous cardiac surgery. Data were obtained retrospectively from our prospective database, medical records and through general practitioners. Results Overall, 74 patients were analysed in the MIDCAB group and 78 in the OPCAB group. Their demographics and EuroSCORE (European System for Cardiac Operative Risk Evaluation) values were comparable (p>0.05). There was no statistically significant difference in the two groups in terms of mortality, recurrent myocardial infarction, postoperative stroke, wound infection, atrial fibrillation or need for reintervention. The MIDCAB group had six conversions to a sternotomy. Eight patients in each group required blood transfusion, with the average transfusion being 1.8 units in the MIDCAB group and 3.2 units in the OPCAB group. The mean duration of ventilation and intensive care unit stay was 5.0 hours and 38.4 hours in the MIDCAB group and 5.4 and 47.8 hours in the OPCAB group. The mean hospital stay was significantly reduced in the MIDCAB population (6.1 vs 8.5 days, p<0.05). Conclusions MIDCAB can be performed safely in appropriately selected patients with outcomes comparable with OPCAB. The potential benefits include shorter hospital stay, reduced need for blood transfusion and faster recovery.
