Abstract
Abstract
Background
End-stage liver disease is associated with significant systemic and haemodynamic alterations that affect cardiac function. Cirrhotic cardiomyopathy remains an ill-defined entity among cardiologists. Understanding the complex interplay between liver dysfunction and cardiac function can lead to a better understanding of the compensatory mechanisms of the heart in liver failure.
Purpose
To investigate whether severity of liver disease affects baseline cardiac output in a large contemporary cohort of patients undergoing liver transplant work-up.
Methods
Consecutive patients that underwent pre-liver transplant (LT) workup between 2010–2017 were included. All patients underwent a resting echocardiogram. Cardiac output (CO) was prospectively recorded at baseline by pulsed-wave Doppler examination of the left ventricular outflow tract from the apical window and systemic vascular resistance (SVR) was calculated as 80 x (mean arterial pressure (MAP)/CO). Severity of liver disease was characterized by the model of end-stage liver disease (MELD) and Child-Pugh scores.
Results
560 patients were included (mean age 57.5±7.7, 74.8% male). Mean MELD score was 19±7 and Child-Pugh Score was 9±3. There was an inverse linear relationship between the severity of liver disease by the MELD score and baseline SVR (rho 0.40, P<0.001). As SVR reduced, there was also a significant rise in baseline CO with a strong inverse correlation between the two variables (rho 0.86, p<0.001). There was a significant linear correlation between the severity of liver disease and baseline CO with both the scores (MELD Score rho 0.42, p<0.001; Child Pugh rho 0.44, p<0.001) (Figure).
Baseline CO in LT Patients by Severity
Conclusions
Baseline CO increased with the severity of liver dysfunction due to a reduced afterload. A higher resting CO may lead to patients encroaching on their cardiac reserve at rest. This provides a pathophysiological insight suggesting a limited role for beta-blockers, particularly in patients with advanced liver cirrhosis.

Abstract
Abstract
Background
Inducible left ventricular outflow tract obstruction (LVOTO) is not infrequently encountered in liver transplant (LT) candidates undergoing cardiac workup. While the impact of LVOTO on adverse cardiovascular haemodynamics is well reported, it is unclear whether it predisposes to perioperative cardiovascular complications following LT.
Purpose
To investigate the effect of inducible left ventricular outflow tract obstruction on perioperative cardiovascular complications in a modern cohort of liver transplant patients.
Methods
Consecutive patients undergoing dobutamine stress echocardiography (DSE) were evaluated from a quaternary LT centre between 2010 and 2017. Inducible LVOTO was defined as LVOT gradient ≥36mmHg. Perioperative major adverse cardiovascular events (MACE) at 30 days and all-cause death were recorded from a prospectively maintained transplantation database and augmented by electronic medical record review.
Results
We evaluated 560 patients who underwent DSE as part of a workup for LT. Of these, 319 progressed to transplant. Inducible LVOTO was observed in 68 patients (21.3%). A higher baseline cardiac output (7.7 L/min vs 7.0 L/min, p=0.002) predicted for development of inducible LVOTO. Seventy-seven patients (4.1%) experienced a MACE including five deaths, 19 cases of heart failure, 11 cardiac arrests, 10 acute coronary syndromes and 46 cases of arrhythmias (VT/AF). Overall MACE occurred in 17/68 patients (25.0%) with LVOTO and 60/251 patients (23.9%) without LVOTO (p=0.85). However, there was a significantly increased risk of resuscitated perioperative cardiac arrest in patients with LVOTO (7.4% vs 2.4%, p=0.04). Patients with LVOTO also required significantly greater volumes of fluid intra-operatively (8.37L vs. 6.71L, p=0.043).
Cardiac Arrest in LT Patients with LVOTO
Conclusions
Inducible LVOTO is a frequent finding occurring in 21.3% of LT candidates. Despite higher intraoperative fluid resuscitation, LVOTO increased the risk of a perioperative cardiac arrest. Further studies are required to confirm these findings and to assess whether patients with LVOTO undergoing liver transplantation may benefit from heightened perioperative surveillance.

Abstract
Guidelines mandate emergent revascularization in patients presenting with ST-elevation myocardial infarction (STEMI) irrespective of gender. We sought to compare the door-to-balloon times and the impact of timely reperfusion on clinical outcomes in women compared with men presenting with STEMI undergoing primary percutaneous coronary intervention (PPCI). We analyzed data from 6,179 consecutive patients presenting with STEMI undergoing PPCI from the Melbourne Interventional Group registry (2005 to 2017). The primary outcome was long-term mortality. Of the 6,179 patients included 1,258 (20.3%) were female. Female patients were older (69 ± 13 vs 62 ± 12 years; p < 0.001), had more co-morbidities and had longer median symptom-to-balloon times (204 [interquartile range {IQR} 154 to 294] vs 181 [IQR 139 to 258] minutes; p < 0.001) and longer median door-to-balloon times (81 [IQR 55 to 102] vs 75 [IQR 51 to 102)] minutes; p < 0.001), while receiving less drug-eluting stents (39% vs 43%; p = 0.01) and having less radial access for PPCI (15% vs 21%; p < 0.001). Furthermore, female patients received less guideline-directed medical therapy than men with less prescription of aspirin (93.4% vs 95.4%; p = 0.02), statins (96.5% vs 97.6%; p < 0.05), and beta blockers (84.3% vs 89.4%; p < 0.001). Unadjusted in-hospital and 30-day mortality rates were higher in women (8.8% vs 6.2%, 9.8% vs 6.9%; p < 0.001). However, on Cox-proportional hazards modeling, gender was not an independent predictor of long-term mortality (hazards ratio 0.99, 95% confidence interval 0.83 to 1.18; p = 0.92) at a mean follow-up of 4.8 ± 3.5 years. In conclusion, in this large multicenter registry of patients with STEMI, women had longer ischemic times, higher risk profiles, and differing interventional approaches compared with men. Addressing these gender inequalities with early identification of symptoms, adherence to guideline-directed medical therapy, as well as higher rates of radial access and use of drug-eluting stents has the potential to further improve outcomes in women with STEMI.

Abstract
AIMS We aimed to confirm the hypothesis that dysglycaemia including in the pre-diabetes range affects a majority of patients admitted with acute coronary syndrome (ACS) and is associated with worse outcomes. METHODS In this prospective observational cohort study, consecutive inpatients aged ≥ 54 years with ACS were uniformly tested and categorised into diabetes (prior diagnosis/ HbA1c ≥ 6.5%, ≥48 mmol/mol), pre-diabetes (HbA1c 5.7-6.4%, 39-47 mmol/mol) and no diabetes (HbA1c ≤ 5.6%, ≤38 mmol/mol) groups. RESULTS Over two years, 847 consecutive inpatients presented with ACS. 313 (37%) inpatients had diabetes, 312 (37%) had pre-diabetes and 222 (25%) had no diabetes. Diabetes, compared with no diabetes, was associated with higher odds of acute pulmonary oedema (APO, odds ratio, OR 2.60, p < 0.01), longer length of stay (LOS, incidence rate ratio, IRR 1.18, p = 0.02) and, 12-month ACS recurrence (OR 1.86, p = 0.046) after adjustment, while no significant associations were identified for pre-diabetes. Analysed as a continuous variable, every 1% (11 mmol/mol) increase in HbA1c was associated with increased odds of APO (OR 1.28, P = 0.002) and a longer LOS (IRR 1.05, P = 0.03). CONCLUSIONS The high prevalence of dysglycaemia and association with poorer clinical outcomes justifies routine HbA1c testing to identify individuals who may benefit from cardioprotective anti-hyperglycaemic agents and, lifestyle modification to prevent progression of pre-diabetes.

Abstract
The risk of major adverse cardiovascular events (MACE) remains high in patients with established coronary artery disease (CAD). The aim of this study was to assess the prognostic significance of established CAD in patients who present with acute coronary syndromes (ACS) using a large established multicenter registry. Consecutive patients from the Melbourne Interventional Group registry who presented with ACS and underwent percutaneous coronary intervention from 2005 to 2015 were included. Patients with a history of myocardial infarction, percutaneous coronary intervention, or coronary artery bypass graft surgery were included in the established CAD cohort. The primary end points were 12-month mortality and 12-month MACE. Of the 12,878 ACS patients included in our study, 3,542 (28%) patients had established CAD. Over the 10-year study period, the proportion of patients presenting with established CAD decreased (30.7% to 25.2%; p-for-overall-trend <0.001). Non-ST elevation myocardial infarction was the most prominent presentation in the established CAD cohort (45.1%) whereas ST-elevation myocardial infarction was the most prominent in the de novo CAD cohort (51%; p< 0.001). The patients in the established CAD cohort were older, had more co-morbidities and were more likely to present with high-risk features such as atrial fibrillation, left main disease, multivessel CAD and left ventricular dysfunction (all p < 0.001). Regarding revascularization in ST-elevation myocardial infarction presentations, symptom-to-door time was shorter, whereas door-to-balloon-time was longer in those with established CAD (p < 0.001). On multivariate analysis, established CAD was an independent risk factor for 12-month MACE (odds ratio 1.40, 95% confidence intervals 1.23 to 1.58, p < 0.001), but not for 12-month mortality (odds ratio 1.08, 95% confidence intervals 0.77 to 1.52, p = 0.66). In conclusion, patients with a history of myocardial infarction or previous revascularization have a higher rate of MACE at 12 months. Despite this they do not appear to suffer from higher mortality.

Abstract
OBJECTIVES Utility of CT coronary angiography (CTA) and coronary artery calcium (CAC) scoring in risk stratification prior to non-cardiac surgery is unclear. Although current guidelines recommend stress testing in intermediate-high risk individuals, over one-third of perioperative major adverse cardiovascular events (MACE) occur in patients with a negative study. This systematic review and meta-analysis evaluates the value of CTA and CAC score in preoperative risk prognostication prior to non-cardiac surgery. METHODS MEDLINE, PubMed and EMBASE databases were searched for articles published up to June 2018. Summary ORs for degree of coronary artery disease (CAD) and perioperative MACE were pooled using a random-effects model. RESULTS Eleven studies were included. Two hundred and fifty-two (7.2%) MACE occurred in 3480 patients. Risk of perioperative MACE rose with the severity and extent of CAD on CTA (no CAD 2.0%; non-obstructive 4.1%; obstructive single-vessel 7.1%; obstructive multivessel 23.1%, p<0.001). Multivessel disease (MVD) demonstrated the greatest risk (OR 8.9, 95% CI 5.1 to 15.3, p<0.001). Increasing CAC score was associated with higher perioperative MACE (CAC score: ≥100 OR 5.1, ≥1000 OR 10.4, both p<0.01). In a cohort deemed high risk by established clinical indices, absence of MVD on CTA demonstrated a negative predictive value of 96% (95% CI 92.8 to 98.4) for predicting freedom from MACE. CONCLUSIONS Severity and extent of CAD on CTA conferred incremental risk for perioperative MACE in patients undergoing non-cardiac surgery. The 'rule-out' capability of CTA is comparable to other non-invasive imaging modalities and offers a viable alternative for risk stratification of patients undergoing non-cardiac surgery.

Abstract
BACKGROUND Endothelin-1 (ET-1) is a vasoconstrictor associated with cardiovascular disease, whereas adrenomedullin (ADM) is a vasorelaxant with cardioprotective properties. We sought to determine the relationship between plasma ET-1 and ADM with coronary circulatory function and long-term major adverse cardiovascular events (MACE). METHODS Thirty-two patients undergoing coronary angiography for chest pain were recruited. Baseline plasma ET-1 and ADM levels were measured. The index of microcirculatory resistance (IMR), coronary flow mediated dilatation (cFMD) and coronary flow reserve (CFR) were measured in a non-obstructed coronary artery. Patients were assessed for MACE over a median period of 8.8 years. RESULTS Plasma ET-1 levels correlated with IMR (r = 0.57; p < 0.01) and ADM levels correlated with CFR (r = 0.50; p = 0.04) and cFMD (r = 0.62; p = 0.01). After adjustment for age, gender and cardiovascular risk factors, the association between ADM and cFMD (β = 0.79; p < 0.01) and between ET-1 and IMR (β = 5.7; p = 0.01) remained significant. IMR was higher, although not statistically significant, in patients with long-term MACE (17.9 ± 5.3 vs. 13.1 ± 6.0 units; p = 0.14). In patients free of MACE, cFMD (9.3 ± 7.6 vs. 2.8 ± 5.0%; p = 0.01) and plasma ADM levels (7.6 ± 5.3 vs. 4.0 ± 1.9 pmol/L; p = 0.07) were higher. CONCLUSIONS Plasma ET-1 and ADM were associated with measures of coronary microvascular and coronary conduit vessel function, respectively. Increased cFMD and elevated plasma ADM were associated with a cardioprotective effect.
