Hospital admission with non-alcoholic fatty liver disease is associated with increased all-cause mortality independent of cardiovascular risk factors
Non-alcoholic fatty liver disease (NAFLD) is common and strongly associated with the metabolic syndrome. Though NAFLD may progress to end-stage liver disease, the top cause of mortality in NAFLD is cardiovascular disease (CVD). Most of the data on liver-related mortality in NAFLD derives from specialist liver centres. It is not clear if the higher reported mortality rates in individuals with non-cirrhotic NAFLD are entirely accounted for by complications of atherosclerosis and diabetes. Therefore, we aimed to describe the CVD burden and mortality in NAFLD when adjusting for metabolic risk factors using a ‘real world’ cohort. We performed a retrospective study of patients followed-up after an admission to non-specialist hospitals with a NAFLD-spectrum diagnosis. Non-cirrhotic NAFLD and NAFLD-cirrhosis patients were defined by ICD-10 codes. Cases were age-/sex-matched with non-NAFLD hospitalised patients. All-cause mortality over 14-years follow-up after discharge was compared between groups using Cox proportional hazard models adjusted for demographics, CVD, and metabolic syndrome components. We identified 1,802 patients with NAFLD-diagnoses: 1,091 with non-cirrhotic NAFLD and 711 with NAFLD-cirrhosis, matched to 24,737 controls. There was an increasing burden of CVD with progression of NAFLD: for congestive heart failure 3.5% control, 4.2% non-cirrhotic NAFLD, 6.6% NAFLD-cirrhosis; and for atrial fibrillation 4.7% control, 5.9% non-cirrhotic NAFLD, 12.1% NAFLD-cirrhosis. Over 14-years follow-up, crude mortality rates were 14.7% control, 13.7% non-cirrhotic NAFLD, and 40.5% NAFLD-cirrhosis. However, after adjusting for demographics, non-cirrhotic NAFLD (HR 1.3 (95% CI 1.1–1.5)) as well as NAFLD-cirrhosis (HR 3.7 (95% CI 3.0–4.5)) patients had higher mortality compared to controls. These differences remained after adjusting for CVD and metabolic syndrome components: non-cirrhotic NAFLD (HR 1.2 (95% CI 1.0–1.4)) and NAFLD-cirrhosis (HR 3.4 (95% CI 2.8–4.2)). In conclusion, from a large non-specialist registry of hospitalised patients, those with non-cirrhotic NAFLD had increased overall mortality compared to controls even after adjusting for CVD
One-year outcomes of percutaneous coronary intervention in native coronary arteries versus saphenous vein grafts in patients with prior coronary artery bypass graft surgery
Background: Patients with prior coronary artery bypass graft (CABG) surgery often require percutaneous coronary intervention (PCI). Data are still limited in regards to the outcomes of native saphenous vein graft (SVG) PCI after CABG. Methods: We performed a retrospective study in a tertiary reference cardiac center of consecutive patients who underwent PCI after CABG. The data were collected for patients who underwent either native or graft PCI from January 2008 to December 2018. Arterial graft PCIs were excluded. Multivariable Cox regression analysis with propensity matching was performed, and major adverse cardiac events (MACE) outcomes including death or myocardial infarction (MI) or revascularization were assessed at 1-year after each index procedure. Results: A total of 435 PCI were performed in 401 patients (209 had native PCI and 192 had graft PCI). Target lesions were classified as following: 235 (54%) native coronary arteries and 200 (46%) SVG. Propensity matching resulted in 167 matched pairs. In multivariable Cox regression graft PCI relative to native PCI was an independent risk factor for MACE (hazard ratio [HR] 1.725, 95% confidence interval [CI] 1.049–2.837) which was primarily driven by increased incidence in revascularization (HR 2.218, 95% CI 1.193–4.122) and MI (HR 2.248, 95% CI 1.220–4.142) and with no significant difference in mortality (HR 1.118, 95% CI 0.435–2.870). Conclusions: Compared with native coronary PCI, bypass graft PCI was significantly associated with higher incidence of MACE at 1-year and this was mainly driven by MI and revascularization

Impact of COVID-19 pandemic on patients with ST-segment elevation myocardial infarction: Insights from a British cardiac center
The current study aimed to examine the impact of COVID-19 pandemic on patient-related delay with ST-segment elevation myocardial infarction (STEMI) at a tertiary center in the United Kingdom. The study demonstrated a significant delay in symptom-to-first medical contact and a higher cardiac troponin-I level on admission in patients with STEMI during the COVID-19 pandemic versus the pre-COVID era
Meta-analysis comparing direct oral anticoagulants to vitamin K antagonists for the management of left ventricular thrombus
Introduction: To compare vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs) treatment in patients with left ventricular (LV) thrombus. The primary outcome was stroke or systemic embolism (SSE). Secondary outcomes were thrombus resolution, bleeding, and death. Areas covered: Five observational studies were included (total n = 700; VKAs n = 480; DOACs n = 220). There was a trend toward less SSE with VKAs compared to DOACs (5.2% vs. 9%; odds ratio [OR] = 0.54, 95% confidence interval [CI] = 0.29–1.01, p = 0.05). No significant difference between VKAs and DOACs in rates of thrombus resolution (61.6% vs. 56.8%; OR = 1.00, 95% CI = 0.58–1.73, p = 0.99), bleeding (8.2% vs. 4.4%; OR = 1.62, 95% CI = 0.69–3.77, p = 0.27), or death (12.7% vs. 11.8%; OR = 1.09, 95% CI = 0.59–2.0, p = 0.79) was noted. In non-primary percutaneous coronary intervention setting, VKAs were associated with less SSE in prespecified analysis (5.2% vs.10.6%; OR = 0.48, 95% CI = 0.25–0.93, p = 0.03). Expert opinion: The current meta-analysis suggests a trend toward higher SSE with the use of DOACs compared to VKAs. Our recommendation is for VKAs to retain the preferred management of LV thrombus with cautious off-label use of DOACs
Identification of high-risk non-ST elevation myocardial infarction at presentation to emergency department. A prospective observational cohort study in North West England
OBJECTIVES:Early access to invasive coronary angiography and revascularisation for high-risk non-ST elevation myocardial infarction (NSTEMI) improves outcomes and is supported by current guidelines. We sought to determine the most effective criteria at presentation to emergency department (ED) to identify high-risk NSTEMI. SETTING:Secondary care centre northwest England with national follow-up. PARTICIPANTS:1642 consecutive patients (median age 59, 52% male) presenting to ED with a primary symptom of chest pain in whom there is suspicion of NSTEMI. PRIMARY AND SECONDARY MEASURES:Multivariate logistic regression analysis for the prediction of all-cause death (primary) and major adverse cardiac event (MACE defined as all-cause death, unplanned coronary revascularisation and adjudicated NSTEMI (third universal definition)) (secondary measure) at 1 year. RESULTS:The incidence of adjudicated NSTEMI was 10.7%, and 1-year mortality was 6.3%. Independent predictors for all-cause death at 1 year were Global Registry of Acute Coronary Events (GRACE) >140, age (per decade increase) and high-sensitive cardiac troponin T (hs-cTnT) >50 ng/L. hs-cTnT >50 ng/L was associated with adjudicated index presentation NSTEMI in the greatest proportion of patients (61.7%). When using MACE at 12 months, as opposed to all-cause death, as an end point History, ECG, Age, Risk factors and Troponin (HEART) score ≥7 was included in the multivariate model and had better prediction of index NSTEMI than GRACE>140. Combining hs-cTnT >50 ng/L and a second independent predictor identified both a high proportion of index NSTEMI and elevated risk of all-cause death at 1 year. CONCLUSIONS:hs-cTnT >50 ng/L or HEART score ≥7 appear effective strategies to identify high-risk NSTEMI at presentation to emergency room with chest pain. Multicentre prospective studies enriched with early presenters, and with competitor high-sensitive and point-of-care troponins, are required to validate and extend these findings.

Balloon-assisted tracking technique as 'a way forward' for transradial intervention
BACKGROUND: In percutaneous coronary interventions, use of the radial artery may be limited by vascular anatomy or vascular complications, such as radial artery spasm, dissection or perforation. The balloon-assisted tracking (BAT) technique is a novel and innovative method to successfully perform transradial procedures in patients with difficult vascular anatomy, severe tortuosity or radial artery spasm. In addition, the BAT technique can serve as a bail-out technique when vascular complications such as artery dissection or perforation occur. OBJECTIVE: We analysed data of all percutaneous coronary intervention patients in whom the BAT technique was undertaken in daily practice and report acute and long-term outcomes. RESULTS: A total of 62 patients were included and, in most patients, the BAT technique was performed for radial spasm. Most patients were administered benzodiazepines or nitrates before the BAT technique was performed. The primary end point, defined as successful passage of the catheter through the artery of the arm using the BAT technique, was 98%. 11% of patients developed a complication within 24 h (haematoma, prolonged pain or visible vascular damage at the end of procedure); all completely recovered at follow-up. No complications occurred during long-term follow-up. CONCLUSION: BAT is a low-risk and easy-to-use technique that increases the success rate of radial artery access and may prevent vascular complications
