Abstract Abstract Background It has been recently suggested that more than 15% of patients with ST-segment–elevation myocardial infarction (STEMI) lack any of the standard modifiable risk factors (cigarette smoking, diabetes, hyperlipidemia, and hypertension -SMuRFs). This claim implies that other factors play a significant role in development of STEMI and has led to considerable interest in genetic causes of coronary heart disease including family history (FHx) Purpose To investigate whether FHx may be a significant driver for STEMI in patients without SMuRFs. Methods We analyzed 11,840 patients with ACSs, without evidence of prior cardiovascular disease (CVD) enrolled in the ISACS-TC (International Survey of Acute Coronary Syndromes in Transitional Countries) registry between January 2010 to January 2021. Main outcome measures were the adjusted rates of STEMI and 30-day mortality from STEMI using multivariable logistic regression models. Patients presenting with non-ST elevation acute coronary syndromes served as controls. Results Among patients with STEMI, at least 1 of the 4 conventional risk factors was present in 88.1% of women and 86.7% of men. Overall, 3,194 patients (27.0%) self-reported a FHx of CV disease, defined as a first-degree relative with premature CV events (men, age <55 years; women, age <65 years). There were 261 (8.2%) patients with FHx but without SMuRFs and 2,933 (91.8%) patients with FHx and SMuRFs. After adjusting for age, and standard risk factors, FHx was associated with a significantly lower incidence of STEMI in patients with SMuRFs, but not in those without SMuRFs (ORs: 0.87; 95% Cl: 0.79 to 0.97 vs 0.80; 95% Cl: 0.58 to 1.12). Prior use of evidence-based medications (aspirin, beta-blockers, ACE inhibitors/ARBs and statins) did not consistently change prior estimates on FHx and SMuRFs (OR: 0.82 95% Cl: 0.71 to 0.96 and OR 0.89 95% CI: 0.54–1.47). Patients who presented with STEMI had a 46% excess risk of 30-day mortality (OR: 1.46; 95% CI: 1.11 to 1.91; p<0.001) compared with controls Conclusions In direct contrast with recent findings, almost 90% of patients with STEMI have SMuRFs. Self-reported FHx is not a significant risk factor for development of STEMI and related high rate of CV mortality in patients without SMuRFs. Although research on genetic causes of heart disease is important, public health policies, and research efforts should place significant emphasis on the 4 SMuRFs and the lifestyle behaviors causing them to reduce the epidemic of STEMI.

Abstract Abstract Funding Acknowledgements Type of funding sources: None. Introduction Verapamil, a calcium channel blocker, is used for treatment of hypertension, paroxysmal supraventricular tachycardia and angina pectoris. It primarily blocks L-type calcium channels preventing excessive influx of calcium into cardiomyocytes, leading to negative inotropic effect, and smooth muscle cells resulting in reduced relaxation of vasculature. With calcium antagonism it also causes negative chronotropic effect. However, there is no data on it’s dose-dependent effects on cardiac dynamic parameters and heart rate on isolated rat heart with hypertension. Purpose To investigate chronic, dose-dependent effects of Verapamil on cardiodynamic parameters in isolated rat heart with hypertension. Methods The present 4-week study was carried out on 24 spontaneously hypertensive Wistar Kyoto male rats (6 weeks old): Control (n = 6), rats treated with 0.5 mg/kg/day of Verapamil (n = 6), rats treated with 5 mg/kg/day of Verapamil (n = 6) and rats treated with 50 mg/kg/day of Verapamil (n = 6). Isolated rat hearts were perfused on Langendorff perfusion apparatus. Results Chronic, low-dose Verapamil treatment significantly depressed function of all cardiodynamic parameters of the hypertensive heart when compared to the rats treated with higher doses of Verapamil (p < 0.001), except on the coronary flow and heart rate when compared to the Control (p= 0.137; p = 1.000, respectively). There was no significant differences between Verapamil in middle dose (5 mg/kg/day) and the Control group in inotropic (p = 0.415) and lusitropic (p = 1.000) effects, while it significantly lowered values of coronary flow (p = 0.002). It achieved significantly lower inotropic, lusitropic and chronotropic effects (p < 0.001) than high Verapamil dose and significantly better inotropic (p = 0.017), lusitropic (p < 0.001), but not chronotropic effects than low-dose Verapamil treatment (p = 0.179). High-dose, chronic treatment with Verapamil significantly intensified function of the isolated rat heart with hypertension when compared to Control and lower doses of Verapamil (p < 0.001), without significant effects on coronary flow (p = 0.363). Conclusions Chronic treatment with Verapamil in high dose achieved better inotropic, chronotropic and lusitropic effects than treatment in low and middle doses of Verapamil, without significant effects on coronary flow. There is dose-depended effect of chronic Verapamil treatment on cardiac function of isolated rat heart with hypertension. Collapse

Abstract Abstract Introduction Amiodarone represents the most widely used antiarrhythmic drug, even though it has been shown that it has negative inotropic and lusitropic effect in healthy hears. On the other hand, dronedarone reduces the risk of recurrent atrial fibrillation, but with increased early mortality related to the worsening of heart failure. However, the mechanisms responsible for these fatal outcomes remain unclear and require further examinations. Purpose To investigate acute, direct effects of Dronedarone and Amiodarone on cardiac contractility, coronary flow and oxidative stress parameters in isolated rat heart with hypertension. Methods The present study was carried out on 18 isolated hearts of spontaneously hypertensive Wistar Kyoto male rats (6 weeks old, bodyweight 200 ± 10 g). After isolation, all hearts were retrogradely perfused according to Langendorff technique with a gradually increment of coronary perfusion pressure (CPP from 40 to 120 cm H2O) and randomly divided into 3 groups: Control (n = 6), Amiodarone (n = 6, isolated hearts perfused with Amiodarone in dose of 3 umol), Dronedarone (n = 6, isolated hearts perfused with Dronedarone in dose of 1.8 umol). During ex vivo protocol continuously were registered cardiac contractility parameters and coronary flow, while from collected coronary venous effluent markers of oxidative stress were measured. All hearts were then fixated and stained with Hematoxylin/eosin. Results Dronedarone severely depressed the function of all cardiodynamic parameters of the heart compared with Amiodarone or Control while Amiodarone intensified the function of the isolated rat heart with hypertension compared to Control (dp/dt max mmHg/s at coronary perfusion pressure 120cmH2O Dronedarone vs. Amiodarone vs. Control 579.733 ± 202.27 vs. 3063.65 ± 467.93 vs. 2682.88 ± 368.75; p < 0.001. dp/dt min mmHg/s 120cmH2O -352.13 ± 204.65 vs. 1960 ± 242.21 vs. -1858.83 ± 118.23; p < 0.001.

Acute administration of Dronedarone decreased the level of NO2- and increased the level of H2O2 , while Amiodarone heightens O2- levels (O2- nmol/min g wt at coronary perfusion pressure 120cmH2O Dronedarone vs. Amiodarone vs. Control 28.62 ± 2.54 vs. 77.3 ± 8.86 vs. 31.72 ± 4.56; p < 0.001.

Pathohistological, structural changes were observed in both, experimental groups. Conclusions Acute administration of Dronedarone depresses cardiac function in isolated, working rat heart with hypertension, with decreasing the NO2- levels, increasing the level of H2O2 and enhanced structural changes when compared to Amiodarone.

Abstract

The aim of this study was to investigate possible interactions between a polymeric emulsifier and a non-ionic surfactant, with a view of achieving better understanding of emulsion stabilisation mechanisms. The polymeric emulsifier used was acrylates/C10-30 alkyl acrylate crosspolymer (Pemulen TR-2(R)), while Polyoxyethylene 20 sorbitan mono-oleate (Polysorbate 80) has been chosen as a model surfactant. Both materials were used within the concentration range relevant for their practical application. A 0.2%w/w aqueous dispersion of polymeric emulsifier, containing various amounts of surfactant (from 0.01 to 1.0% w/w) was used throughout the study. Interfacial aspects of the proposed polymer/surfactant interactions were analysed by means of surface tension measurements. Changes in the network structure of the test dispersions were quantified by continuous shear rheometry, supported by the texture analysis. To analyse the influence of hydrophobic alkyl groups present on the Pemulen TR-2(R) chains, an unmodified, hydrophilic polyacrylic acid polymer, Carbopol 934P(R), was assessed under the same conditions. The results obtained by both surface tension and rheological studies have revealed large differences in behaviour of the two polymers in the presence of the model surfactant. Pemulen TR-2(R) was shown to desorb the surfactant from the surface, within the whole concentration range studied. Furthermore, an increase in viscosity and texture profile parameters with increasing Polysorbate 80 concentration up to 0.3% w/w was evident in the case of Pemulen TR-2(R) dispersions. This was followed by a decrease in the gel network strength at higher surfactant concentrations. On the other hand, Carbopol 934P(R) has shown no signs of surfactant desorption and only small changes in the network structure with the increasing concentration of surfactant. It is shown in this study that an interaction between a polymeric emulsifier Pemulen TR-2(R) and a non-ionic surfactant Polysorbate 80 does occur in their aqueous dispersion, and that it is: (a) hydrophobic in nature; (b) concentration-dependent; and (c) has an impact on the rheological properties of dispersion.
