Introduction: There are worldwide reports that hospital admissions for acute coronary syndrome (ACS) have declined during the COVID-19 pandemic. Chios is a Greek island with only one confirmed coronavirus case during the lockdown. This study aimed to compare admissions for ACS in Chios General Hospital, Greece, between the COVID-19 lockdown period and the same period in the previous year. Methods: Retrospective record analysis of an isolated insular population referring to the only district hospital on the island. ACS incidence, type, and complications were recorded and compared between 26/02/2020-04/05/2020 and between 26/02/2019-04/05/2019. Results: ACS hospital admissions in 2020 were 1.72/10,000 inhabitants vs. 1.03/10,000 inhabitants in 2019 ( p = 0.317). No differences in ACS type, duration from symptom onset to first medical contact, hemodynamic status, left ventricular function at discharge, or complications were recorded. Conclusion: The incidence of ACS did not decrease and the prognosis was not worse during the COVID-19 pandemic in a strictly isolated Greek insular population not overwhelmed by coronavirus cases., Competing Interests: None by all authors., (Copyright ©2024 The Author(s).)

Introduction: Chios Mastiha essential oil (CMO) is a natural product extracted from the resin of Mastiha, possessing antioxidant, anti-microbial, anti-ulcer, anti-neoplastic, and cholesterol-lowering capabilities in vitro, and its hypolipidemic effect was confirmed in animal studies. Yet, there are no randomized, placebo-controlled clinical studies in the literature regarding CMO's hypolipidemic effects in humans. A prospective, randomized, placebo-controlled study was designed to study the hypolipidemic effect of CMO capsules on healthy volunteers with elevated cholesterol., Methods: 192 healthy volunteers were screened and 160 of them with total cholesterol> 200 mg/dl participated in the study. They were randomized with a 2:1 ratio of receiving CMO capsules (200 mg mastiha-oil/capsule) and placebo for 8 weeks respectively. 113 patients received CMO and 47 were randomized in the control group, and all of them completed the follow-up period., Results: After 8 weeks of CMO administration, total and LDL cholesterol were significantly lower in the CMO compared to the placebo group 215.2 ± 27.5 vs 237.0 ± 27.9 mg/dl (p < 0.001) and 135.0 ± 26.1 vs 153.0 ± 23.3 mg/dl (p < 0.001) respectively. No gastrointestinal adverse events or liver or renal toxicity were reported. Additionally, in the CMO group total cholesterol was significantly decreased by 20.6 mg/dl (9%), LDL by 18.1 mg/dl (12%), triglycerides by 21.8 mg/dl (15%), and glucose by 4.6 mg/dl (5%) and HDL was increased by 2.4 mg/dl (5%), compared to their baseline values., Conclusion: The MASTIHA-OIL study showed the efficacy and safety of CMO in reduction of total and LDL cholesterol after 8 weeks of administration in healthy volunteers with elevated cholesterol levels., (Copyright © 2023 Hellenic Society of Cardiology.

Background: Current guidelines recommend a rhythm control strategy in patients with symptomatic atrial fibrillation (AF) while catheter ablation has been shown to be a safer and more efficacious approach than antiarrhythmic medications., Methods: HECMOS was a nationwide snapshot survey of cardiorenal morbidity in hospitalized cardiology patients. In this sub-study, we included 276 cases who had a history of AF, particularly on the rhythm strategy, and catheter ablation procedures had been performed before the index admission., Results: Among 276 AF patients (mean age: 76.4 ± 11.5 years, 58 % male), 60.9 % (N = 168) had persistent AF and 39.1 % (N = 108) had paroxysmal AF. Heart failure was the main cause of admission in 54.3 % (N = 145) of the patients, while 14.1 % (N = 39) were admitted due to paroxysmal AF, 7.3 % (N = 20) due to bradyarrhythmic reasons, and 6.5 % (N = 18) suffered from acute coronary syndrome. Most importantly, heart failure with reduced ejection fraction was present in 76 (27 %) patients. Only 10 patients out of the total (3 %, mean age 59.7 years) had undergone AF ablation while electrical cardioversion had been attempted in 37 (13.4 %) patients. Interestingly, in this AF population with heart failure, 3.6 % (N = 10) had a defibrillator implanted (4 single-chamber), and only 1.5 % (N = 4) had a cardiac resynchronization therapy defibrillator (CRT-D)., Conclusion: High prevalence of persistent AF was detected in hospitalized patients, with heart failure being the leading cause of admission and main co-morbidity. Rhythm control strategies are notably underused, along with CRT-D implantation in patients with AF and heart failure., Competing Interests: Declaration of competing interest None., (Copyright © 2023 Elsevier Ltd.

Introduction: The use of generic drugs is continuously growing; however, there are limited epidemiological data regarding the therapeutic equivalence of each original drug formulation with its generic counterparts. We evaluated the 12-month composite endpoint of recurrent acute myocardial infarction, ischaemic stroke, cardiac deaths, or hospitalisation due to a major bleeding in acute coronary syndrome (ACS) patients treated with original clopidogrel or a generic clopidogrel formulation, in relation to sociodemographic and clinical characteristics., Material and Methods: Consecutive Greek ACS patients ( n = 1194) hospitalised in the Aegean islands and the Attica region were enrolled. Clopidogrel treatment was recorded either as original clopidogrel hydrogen sulphate (Plavix ® /Iscover ® ) or as a generic clopidogrel besylate formulation (Clovelen ® ). The composite endpoint was recorded at 12-month follow-up., Results: The 12-month composite endpoint was 3.9% (4.6% in the Aegean islands and 3.5% in the Attica area, p > 0.05). The respective incidence in men was 4.0% and in women 3.8% ( p > 0.05). Overall, generic and original clopidogrel use was 87% and 13% of patients, respectively. No significant differences were observed between original and generic clopidogrel use and 12-month composite endpoint incidence. Subgroup analysis with gender, region of residence, and clinical and lifestyle factors as strata did not reveal any significant outcomes. Haemorrhage incidence did not exceed 1% in the total sample., Conclusions: The use of a generic clopidogrel besylate formulation was quite high in both urban and insular areas of Greece and had similar efficacy and safety profile with the original clopidogrel salt, supporting the routine use of this low-cost generic clopidogrel in the management of cardiovascular disease patients., Competing Interests: This study was partially supported by grants from ELPEN (Greece), manufacturer of the clopidogrel besylate generic formulation (Clovelen®) used in the present study. However, the study was investigator initiated, and the sponsor had no involvement in the design and conduct of the study, in the collection, management, analysis, and interpretation of the data or in the preparation, review or approval of the manuscript. The corresponding author had full access to all the data in the study and had the final responsibility for the decision to submit for publication. The authors have indicated that they have no other conflicts of interest regarding the content of this article., (Copyright: © 2020 Termedia & Banach.)

Background: Chios mastic gum (CMG) possesses anti-oxidant, anti-inflammatory, anti-atheromatic, lipid- and glucose-lowering properties. We evaluated the effects of CMG on cholesterol and fasting plasma glucose (FPG) levels of healthy volunteers., Design: A prospective, randomized, placebo-controlled, pilot study., Methods: One hundred and seventy nine volunteers with total cholesterol levels >200 mg/dl were randomized to four groups. Finally, 156 volunteers completed the follow-up period and were analysed: (1) control group (C, n = 23), receiving placebo; (2) total mastic (TM, n = 72) receiving daily a total dose of 1 g of crude CMG (330 mg capsules, tid); (3) polymer-free mastic (PFM, n = 33), receiving daily a total dose of 1 g of polymer free mastic (330 mg caps, tid); and (4) powder mastic (PM, n = 28), receiving daily a total dose of 2 g of crude CMG., Results: After eight weeks, the TM group reduced total cholesterol by 11.5 mg/dl (p < 0.05) and FPG by 4.5 mg/dl (p < 0.05) adjusted for age, gender, BMI and baseline characteristics. The effect was stronger in overweight and obese patients (BMI > 25), with an estimated mean reduction of total cholesterol by 13.5 mg/dl (p < 0.05) and FPG by 5.1 mg/dl (p < 0.05). Administration of PFM and PM resulted in no statistically significant alteration. No effect was observed on LDL, HDL, triglycerides, uric acid and CRP. No gastrointestinal, liver or renal adverse events were recorded., Conclusions: CMG has a significant lowering effect on total cholesterol and glucose levels of healthy volunteers, with excellent tolerance and no detectable side effects, especially in overweight and obese individuals., (© The European Society of Cardiology 2015.)
