SummaryAt least five studies based on more than twenty thousand healthy subjects indicated that fibrinogen is an independent risk factor for cardiovascular events; less clear-cut is the relation between factor VII and risk for arterial thrombotic disorders, which was demonstrated in two of the three studies investigating this association. However, no study has investigated the behaviour of fibrinogen and factor VII in an adolescent population. In a study of Preventive Medicine and Education Program, fibrinogen (clotting method) and factor Vllag (ELISA), in addition to other metabolic parameters, life-style and familial history, were investigated in 451 students (313 females and 138 males, age 15-17 years) from two high schools of Florence. Fibrinogen levels were significantly higher in women than in men, whereas factor Vllag levels did not significantly differ. Both fibrinogen and factor Vllag significantly correlated with total cholesterol (p <0.05) while only fibrinogen correlated with body mass index (p <0.01). Factor Vllag was significantly correlated with systolic blood pressure (p <0.001). This study provides information on coagulation risk factors in a population of adolescents which may be of importance in planning coronary heart disease prevention programs.

Abstract Introduction High prevalence of cardiovascular events at northern latitudes determines the necessity of studying mechanisms of formation and early diagnosis of atherosclerotic process. Purpose To determine the most unfavorable prognostic factors that provide the percentage of correct prediction and high accuracy in detection of atherosclerotic plaque (ASP) in common carotid arteries (CCA) in rotational shift workers in the Arctic. Methods Within 2010–2012 a study of 424 males aged 30–59 years at the medical unit “Gazprom dobycha Yamburg” (Yamburg settlement, 68°N) was performed. Patients were randomized into 2 groups according to blood pressure (BP). Gr.I included 294 people with BP more than 140/90 mmHg, arterial hypertension (AH) of 1,2 stage and Gr.II included 130 people with BP less than 140/90 mmHg. Groups did not differ in age (46.9±5.8 years, p=0.435); total work experience in the Arctic: 16.5±6.8 years (p=0.512) and rotational shiftwork duration: 12.5±4.6 years (p=0.597). Office BP was 149.4±13.3/97.1±7.3 mmHg in Gr.I and 123.4±7.5/80.5±5.5 mmHg in Gr.II. Ultrasound examination of carotid arteries with determination of presence or absence of ASP in CCA and estimation of stenosis using NASCET method were performed; ambulatory blood pressure monitoring was conducted; blood glucose levels, total cholesterol, high-density lipoprotein cholesterol, low density lipoprotein cholesterol were determined. Statistical analysis was carried out using R (v. 3.6.1) programming language for statistical data processing of R Studio application package (v. 1.2.1335). Results Signs of CCA atherosclerosis were revealed in 56% of patients with AH and in 25% of those without AH. According to multivariate analysis, three variables with the most significant set of predictors, associated with ASP in CCA with the percentage of correct prediction of 75.9% were selected by step-by-step method: diastolic BP24 (&lt;0.0001), glucose (0.0167) and cholesterol (0.0439). Based on the obtained model, it was concluded that 1 mmHg increase in diastolic BP24 increases the risk for developing ASP by 5.9%, Exp. (Beta) = 1.059, 1 mmol/l increase in glucose and cholesterol escalates the risk by 44.1% and 25.2%, respectively: Exp. (Beta) = 1.441 and Exp. (Beta) = 1.252. Conclusion The data obtained will improve accuracy for the early diagnosis of subclinical atherosclerosis of CCA, allow to prescribe lipid-lowering therapy timely and reduce the risk of adverse cardiovascular events in rotational shift workers in the Arctic.

Abstract Introduction Nocturnal blood pressure (BP) and early morning BP surge have consistently been found to be a better prognostic marker of cardiovascular outcome than daytime BP. Most anti-hypertensive show greater blood pressure-lowering effect in the first 12 hours compared to the next 12 hours. Several prospective studies have shown better BP regulation and improved cardiovascular risk when anti-hypertensive are ingested at bedtime versus at awakening. Purpose In patients with hypertension does evening dosing of anti-hypertensive compared to morning dosing led to better reduction in pressure, blood pressure control and reduced cardiovascular morbidity. Methods A meta-analysis was performed based on randomized controlled trials obtained from Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, Medline and Medline ahead of print published between 2000 and 2020. Main outcome measures include mean 24 hour systolic and diastolic blood pressure, cardiovascular events as well as prevalence of blood pressure in control. Data synthesis and analysis was done using RevMan 5.3 using a random effects model. Results A total of 40 randomized controlled trials, representing 44,167 patients were included in this meta-analysis. Most studies evaluate the administration of mixed anti-hypertensive with ≥1 medication ingested at bedtime, calcium channel blockers (CCBs) or angiotensin receptor blockers (ARBs) with sample sizes ranging from 30 to 19,084 patients. Evening administration of anti-hypertensive was found to significantly lower 24-hour systolic blood pressure (Mean difference = −1.05, 95% CI: −2.01 to −0.10, p=0.03) and 24-hour diastolic blood pressure (Mean difference = −1.09, 95% CI: −1.68 to −0.50, p=0.0003). Prevalence of controlled blood pressure was found to significantly increase with evening dosing (RR=1.15, 95% CI: 1.03 to 1.28, p=0.01). Significant reduction in cardiovascular events were found in the evening dosing group (RR=0.48, 95% CI: 0.03 to 0.68, p=&lt;0.00001). Discussion Reduction in night-time blood pressure especially among non-dippers as reported in previous studies and higher prevalence of controlled blood pressure may explain the greater than 50% reduction in cardiovascular events in the evening dosing group. This marked benefit from a simple and inexpensive strategy certainly has great potential to benefit patients in practice. Even so, few studies have reported the prevalence of blood pressure in control (9 studies) and cardiovascular events (6 studies). Few has also studied this in geriatric populations where night-time hypotension and hypoperfusion may bring the most impact. Conclusion For patients with hypertension, evening dosing significantly improves blood pressure control and reduces the risk for cardiovascular events. Careful selection of anti-hypertensive administration time in patients is recommended given the possible benefits.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction There is some evidence suggesting that exaggerated hypertensive response to exercise (HRE) may be associated with higher risk of future cardiovascular events, however the relationship between systolic blood pressure (SPB) during exercise test and stroke is not fully understood. Purpose To evaluate the ability to predict the risk of stroke in patients with HRE in exercise test. Methods Single-center retrospective study of consecutive patients submitted to exercise test from 2012 to 2015 with HRE to stress test. HRE was defined as a peak systolic blood pressure (PSBP) &gt; 210 mmHg in men and &gt; 190 mmHg in women, or a rise of the SBP of 60 mmHg in men or 50 mmHg in women or as a diastolic blood pressure &gt; 90 mmHg or a rise of 10 mmHg. Patient’s demographics, baseline clinical characteristics, vital signs during the stress test and the occurrence of stroke during follow-up were analysed Results We included 458 patients with HRE (76% men, 57.5 ± 10.83 years). The most frequent comorbidities were hypertension (83%), dyslipidaemia (61%), previously known coronary disease (32%), diabetes (28%) and smoking (38%). Atrial fibrillation was present in 5.9% of patients. During a mean follow-up of 60 ± 2 months, the incidence of stroke was 2.1% (n = 8), all with ischemic origin. Considering the parameters analysed on exercise test, only PSBP demonstrated to be an independent predictor of stroke (HR 1.042, CI95% 1.002-1.084, p = 0.039,) with moderate ability to predict stroke (AUC 0.735, p = 0.0016) with a most discriminatory value of 203 mmHg (sensibility 56%, specify 67%). Regarding baseline characteristics, after age, sex and comorbidities adjustment, previously controlled hypertension was found to be an independent protective factor of stroke (OR 4.247, CI 95% 0.05-0.9, p = 0.036) and atrial fibrillation was an independent predictor of stroke occurrence (HR 8.1, CI95% 1.4-46.9, p = 0.018). Atrial fibrillation was also associated with hospitalization of cardiovascular cause and major cardiovascular events occurrence (mortality, coronary syndrome and stroke). Baseline SBP was associated with atrial fibrillation development (p = 0.008). Conclusion According to our results, PSBP during exercise test is an independent predictor of stroke occurrence and should be considered as a potencial additional tool to predict stroke occurrence, particularly in high risk patients. The identification of diagnosed hypertension as a protective factor of stroke may be explained by the cardioprotective effect of antihypertensive drugs.
