BackgroundLow free triiodothyronine (fT3) level is strongly associated with poor prognosis in various patient populations. However, the role of fT3 in the risk of clinical outcomes in myocardial infarction with non-obstructive coronary arteries (MINOCA) has not been studied. Our study aimed to evaluate the association between low fT3 levels and the clinical outcomes of MINOCA patients.MethodsA total of 218 MINOCA patients without a history of thyroid disease were enrolled in the study. Demographic, baseline clinical data, thyroid hormones, and other biochemical parameters were assessed in all patients. According to the fT3 levels, the present study was classified into two groups: the low fT3 group (fT3<3.5 pmol/L) and the normal fT3 group (fT3 3.5-6.5 pmol/L). The endpoint of the study was major adverse cardiac events (MACE).ResultsFifty-nine patients were in the low fT3 group and 159 patients were in the normal fT3 group. Over the two years of follow-up, 36 MACE have occurred. The occurrence of MACE was higher in the low fT3 group compared with normal fT3 group (25.4% vs 13.2%; P=0.031). Kaplan-Meier survival curves showed a significantly increased risk of MACE in patients with low fT3 (log-rank P=0.027). Multivariable logistic regression analysis stated that high fT3 was independently associated with lower risk of MACE after two years of follow up (OR, 0.623; 95% CI, 0.399- 0.972; P=0.037).ConclusionLow fT3 levels were significantly associated with increased risk of MACE in patients with MINOCA. This finding suggests that the fT3 levels may serve as a potential biomarker in risk stratification of MINOCA patients.

Abstract Purpose A long-lasting remission of acromegaly after somatostatin analogues (SAs) withdrawal has been described in some series. Our aim was to update the disease evolution after SAs withdrawal in a cohort of acromegalic patients. Methods We retrospectively evaluated 21 acromegalic patients previously included in a multicentre study (Ronchi et al. 2008), updating data at the last follow-up. We added further 8 patients selected for SAs withdrawal between 2008–2018. Pituitary irradiation represented an exclusion criterion. The withdrawal was suggested after at least 9 months of clinical and hormonal disease control. Clinical and biochemical data prior and after SAs withdrawal were analysed. Results In the whole cohort (29 patients) mean age was 50 ± 14.9 years and 72.4% were females. In 69% pituitary surgery was previously performed. Overall, the median time of treatment before SAs withdrawal was 53 months (IQR = 24–84). At the last follow up in 2019, 23/29 patients (79.3%) had a disease relapse after a median time of 6 months (interquartile range or IQR = 3–12) from the drug suspension, while 6/29 (20.7%) were still on remission after 120 months (IQR = 66–150). IGF-1 levels were significantly lower before withdrawal in patients with persistent remission compared to relapsing ones (IGF-1 SDS: -1.5 ± 0.6 vs -0.11 ± 1, p = 0.01). We did not observe any other difference between patients with and without relapse, including SAs formulation, dosage and treatment duration. Conclusion A successful withdrawal of SAs is possible in a subset of well-controlled acromegalic patients and it challenges the concept that medical therapy is a lifelong requirement.

Abstract Funding Acknowledgements Type of funding sources: None. Background Myocardial bridging (MB) is associated with endothelial dysfunction and may represent a cause of angina in patients with non-obstructive coronary artery disease (NOCAD). Purpose  Herein, we assessed the interplay between MB and coronary vasomotor disorders, evaluating also their prognostic relevance in patients with myocardial infarction and non-obstructive coronary arteries (MINOCA) or stable NOCAD. Methods We prospectively enrolled consecutive NOCAD patients undergoing intracoronary acetylcholine provocative test to assess the presence of epicardial or microvascular spasm in patients with suspected angina or MINOCA. Myocardial bridging was diagnosed by coronary angiography. The incidence of major adverse cardiac events (MACE), defined as the composite of cardiac death, non-fatal MI and rehospitalisation for unstable angina, was assessed at follow-up. We also assessed angina status using Seattle Angina Questionnaires (SAQ). Results We enrolled 310 patients (mean age 60.6 ± 11.9; 136 [43.9%] men; 169 [54.5%] stable NOCAD and 141 [45.5%] MINOCA). MB was found in 53 (17.1%) patients. MB was an independent predictor of spasm and MINOCA (p < 0.05). At follow-up (median 22 months, interquartile range [13-32]), patients with MB had a higher rate of MACE and a lower SAQ score (all p < 0.001) compared with patients without MB. The rate of MACE was considerably higher in patients with both spasm and MB than in the remaining patients (12/42 [28.6%] vs. 13/268 [4.8%], p < 0.001). Conclusion Among patients with NOCAD coronary spasm associated with MB predicts a worse clinical presentation with MINOCA and a worse clinical outcome at medium-long term follow-up, thus identifying a high-risk subset of patients with MB with relevant therapeutic implications.

Abstract Background Recent clinical study suggests newer-generation drug-eluting stents (DES) that combine ultrathin strut and nano-coating with biodegradable polymers sirolimus-eluting stent (BP-SES) could improve long-term clinical outcomes in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) over current generation DES. However, safety profiles in very early phase have not been systematically addressed. Objective and method We exploratory investigate early vascular response following BP-SES implantation in patients with STEMI to reveal mechanism of the favorable clinical outcomes in recent studies using frequency domain-optical coherence tomography (FD-OCT). Consecutive twenty patients with STEMI who underwent FD-OCT immediately after primary PCI and were eligible for follow-up FD-OCT at 2 weeks after implantation were enrolled between June 2018 and November 2019. Results Twenty patients (age 62.7±11.3 years, male 85.0%) were enrolled with frequencies of hypertension (45.0%), diabetes mellitus (35.0%), dyslipidemia (55.0%) and smoking (80.0%). Aspiration catheter were used in all patients, and 1.13±0.34 stents were used. Only one patient (5.0%) received chronic antiplatelet therapy with aspirin prior to the onset of STEMI. All patients started to receive prasugrel as thienopyridine from this event and continued dual antiplatelet therapy for 2 weeks. The percentage of uncovered struts significantly decreased from post-procedure to 2W follow-up (69±18% post-procedure versus 30±11% at 2W follow up, p<0.0001). Malapposed struts also decreased (5.6±5.7% post-procedure versus0.9±1.2% at 2W follow up, p<0.0001).The average protrusion area of athero-thrombotic burden numerically decreased (0.37±0.19 at post-procedure versus 0.34±0.14 mm2 at 2W follow up, p=0.19) and its volume showed similar tendency (10.60±6.40 at post-procedure versus 9.36±5.14 mm3 at 2W follow up, p=0.19). Conclusion(s) This study firstly elucidated very early vascular responses following ultrathin strut BP-SES implantation in STEMI patients, showing early progression of strut coverage and resolution of athero-thrombotic materials. This technology may have a potential to overcome the current generation DESs in this clinical setting. Thrombus, uncovered and malapposed struts Funding Acknowledgement Type of funding source: None

Background: Radiofrequency current ablation (RFA) of ventricular tachycardia (VT) focuses on endocardial (endo) substrates. However, if endo RFA fails, an epi approach is a potential treatment option. We report a single centre experience of epi VT ablation. Patients and Methods: Between 06/2005 and 02/2008 42 pts (14 female, mean age 49 ± 18 years) underwent electroanatomical endo and epi mapping and ablation for intractable VT, syncope or VT storm with multiple ICD discharges. Pts with normal heart (n=7), ischemic cardiomyopathy (ICM; n=8), NICM (n=11), ARVD (n=8), LV-aneurysm (n=7) or sarcoidosis (n=1) were studied. Mean LV ejection fraction was 45±12%. 20/42 had had at least 1 previous ablation attempt for VT (range 1– 4 ablations). Acute success was defined as non-inducibility of the previously inducible VT. Chronic success was defined as recurrence of any VT. Results: Acute procedural success rate was 79% (30/38). In 4 pts VTs were not inducible during EPS. In 28/42 pts endo mapping revealed no pathologic potentials. In 23/38 pts and 7/38 the succesful RFC ablation site was epi and endo, respectively. In 9/38 pts endo ablation failed and VT could only be ablated from epi. Further 7/38 pts needed both endo and epi ablation. In In 4/8 failed ablations epi RFC ablation was impossible due to failed access to target site (adhesions; n=2), close vicinity of a coronary artery (n=1) or the phrenic nerve (n=1). Procedure duration was 263±97 min. Unfortunately, 1 pt died due to perforation of RV and 1 pt had severe hepatic bleeding after epi puncture. One pt died in cardiogenic shock 1 d after the procedure. In 2 pts a sterile pericarditis occurred which resolved without any further intervention. After a median follow-up of 293 days (1–929 days) 53% of pts were alive and free from any VT. Conclusion: In pts with failed endo RFC ablation for VT due to different etiologies epi RFC ablation was acutely successful in 61% of pts with a moderate chronic success rate. However, major complications occured in approximately 5% of pts. Epi mapping should be considered if endo pathologic potentials are absent or if endo ablation failed.
