The study evaluated the extent to which high normal blood pressure (HNBP), elevated BP, and Stage 1 hypertension predict 10-year incidence of cardiovascular disease (CVD). A population-based, ...prospective cohort study was conducted among 3042 randomly selected Greek adults, aged 18-89 years. Following 10-years follow-up (2002-2012), incidence of non-fatal and fatal CVD (ICD-10) was achieved in 2020 participants. The analytic sample (n = 1403) excluded hypertensive patients. At baseline, the prevalence rate of HNBP, elevated BP, and Stage 1 hypertension was 44.6% (n = 626), 29.0% (n = 408), and 15.5% (n = 218), respectively. During follow-up, the 10-year combined (fatal or non-fatal) CVD incidence rates in HNBP, elevated BP, and Stage 1 hypertensive individuals were 15.6% (n = 98), 12.0% (n = 49), and 22.5% (n = 49), respectively, as compared to 6.3% (n = 49) in normotensives (all p's < 0.0001). As compared to normotensives (and following the adjustment for known demographic, lifestyle and clinical confounding factors), HNBP participants had a 1.5-fold (Adjusted Hazard Ratio, Adj. HR: 1.49; 95% CI: 1.00-2.20) increased risk of 10-year CVD events. Similarly, Stage 1 hypertensive participants had an approximately twofold (Adj. HR: 1.90; 95% CI: 1.16-3.08) increased risk for 10-year CVD, particularly among males (Adj. HR: 2.03; 95% CI: 1.08-3.83). However, individuals with elevated BP did not exhibit a differential risk for developing 10-year CVD events (Adj. HR: 1.28; 95% CI: 0.82-2.02). Therefore, since HNBP and Stage 1 hypertension individuals exhibit a notable increased risk of 10-year fatal and non-fatal CVD, the implementation of targeted primary and secondary prevention interventions may deter both CVD and related adverse health outcomes.
Purpose: To examine the association of egg intake with 10-year risk of cardiovascular disease (CVD) and other cardiometabolic risk factors in a sample of individuals of Mediterranean origin. Methods: ...In 2001−2002, n = 1514 men and n = 1528 women (>18 years old) from the greater Athens area, Greece, were enrolled. Information on any egg intake, eaten as a whole, partly or in recipes was assessed via a validated semi-quantitative food frequency questionnaire. Follow-up for CVD evaluation (2011−2012) was achieved in n = 2020 participants (n = 317 CVD cases). Results: Ranking from lowest (<1 serving/week) to intermediate (1−4 servings/week) and high (4−7 servings/week) egg consumption tertiles, lower CVD incidence was observed (18%, 9% and 8%, respectively, p-for-trend = 0.004). Unadjusted analysis revealed that 1−3 eggs/week and 4−7 eggs/week were associated with a 60% and 75%, respectively, lower risk of developing CVD compared with the reference group (<1 egg/week). When adjusting for sociodemographic, lifestyle and clinical factors, significance was retained only for 1−3 eggs/week (hazard ratio (HR) = 0.53, 95% confidence interval (95% CI) = 0.28, 1.00). When total saturated fatty acid (SFA) intake was taken into account, this inverse association was non-significant. Multi-adjusted analysis revealed that in participants of low SFA intake, 1 serving/day increase in egg intake resulted in 45% lower risk of developing CVD. In the case of higher SFA consumption, only 1−3 eggs/week seemed to protect against CVD (HR = 0.25, 95% CI = 0.07, 0.86). In the case of intermediate cardiometabolic disorders, no significant trend was observed. Conclusions: Overall dietary habits principally in terms of SFA intake may be detrimental to define the role of eggs in cardiac health.
We evaluated the prevalence of obesity in relation to adherence to a Mediterranean diet.
We conducted a cross-sectional survey that randomly enrolled 1514 men (18 to 87 y old) and 1528 women (18 to ...89 y old) with no history of cardiovascular disease. Anthropometric indices were measured and frequency of various foods consumed during a usual week was recorded. Adherence to a Mediterranean diet was assessed by a diet score that incorporated the inherent characteristics of this diet.
Prevalences of overweight and obesity were 53% and 20% in men and 31% and 15% in women. An inverse relation was observed between diet score, waist-to-hip ratio (
r = −0.31,
P < 0.001), and body mass index (
r = −0.4,
P < 0.001) after adjusting for sex and age. Greater adherence to the Mediterranean diet (i.e., highest tertile) was associated with a 51% lower odds of being obese (odds ratio 0.49, 95% confidence interval 0.42 to 0.56) and a 59% lower odds of having central obesity (odds ratio 0.41, 95% confidence 0.35 to 0.47) compared with a non-Mediterranean diet (i.e., lowest tertile) after controlling for age, sex, physical activity status, metabolism, and other variables.
We observed an inverse relation between adherence to a Mediterranean dietary pattern and prevalence of obesity in a free-eating, population-based sample of men and women, irrespective of various potential confounders.
The study aimed to assess the trajectories of lifestyle characteristics and their association with 20-year cardiovascular disease (CVD) incidence. In 2002, 3042 Greek adults (aged: 45 (12) years) ...free of CVD were enrolled. In 2022, the 20-year follow-up was performed on 2169 participants; of those, 1988 had complete data for CVD. The 20-year CVD incidence was 3600 cases/10,000 individuals; the man-to-woman ratio was 1.25, with the peak difference in the 35-45 age group (i.e., 2.1); however, a reversal of the trend was observed in the age-groups 55-65 and 65-75, with a resumption of an almost equal incidence in those >75 years. In multi-adjusted analysis, age, sex, abnormal waist circumference, hypercholesterolemia, hypertension, and diabetes were positively associated with 20-year CVD risk, explaining 56% of the excess CVD risk, whereas an additional 30% was attributed to lifestyle trajectories; being physically active throughout life-course and being close to the Mediterranean diet were protective, while continuous smoking was detrimental against CVD risk. Mediterranean diet adherence protected against CVD development even if not sustained, while quitting smoking or engaging in physical activities during the 20-year observation did not offer any significant protection. A life-course personalized approach that is cost-effective and long-term sustained is needed to prevent CVD burden.

The failing heart is characterized by a depleted metabolic energy reserve and the upregulation of several molecular mechanisms leading to cardiac hypertrophy, inflammation, fibrosis, angiogenesis, ...and apoptosis. Dietary or non-dietary supplementation of vitamins could potentially benefit energy balance.
The objective of the present study was to evaluate all available information on vitamins supplementation in patients with chronic HF for possible beneficial effect on metabolic, inotropic, chronotropic and hemodynamic indices.
We searched MEDLINE via Pubmed by using the following terms: "chronic heart failure" OR "cardiomyopathy" AND "vitamins", "vitamin A", "B complex vitamins", "vitamin C", "ascorbic acid", "vitamin D", "retinol", "vitamin E", "thiamine", "riboflavin", "niacin", "pyridoxine", "cobalamin", "folate", "pantothenic acid", "biotin", "tocopherol" and combinations of them.
Data regarding supplementation of micronutrients in HF for most vitamins were sparse, and the inference about cardiovascular outcomes was obscured by the heterogeneity of studies, high inherent morbidity, and mortality of this group of high-risk patients, limited sample sizes in certain studies, unclear design and lack of head to head comparisons. Most vitamins in human trials failed to offer survival, or robust beneficial effect. Mostly indirect favorable evidence is derived from patients with deficiencies of certain micronutrients rather than their ad hoc supplementation.
While vitamins and micronutrients are promising compounds for optimizing myocardial metabolism and homeostasis in HF, additional randomized clinical trials of larger scale are warranted to demonstrate the benefits of their supplementation in this high risk group of patients.
Accumulating evidence suggests a direct role of Uric Acid (UA) on Left Ventricular (LV) diastolic function in chronic kidney disease and Heart Failure (HF) patients. Recently, UA has been linked to ...LV Hypertrophy (LVH) and Diastolic Dysfunction (DD) in women with preserved Ejection Fraction (pEF) but not in corresponding men. We sought to assess if UA could predict indices of DD in hypertensive subjects with pEF independently of gender.
We consecutively recruited 382 apparently healthy hypertensive subjects (age: 61.7±10.7, women: 61.3%, median EF: 64%). In 318 patients in sinus rhythm, LV mass-indexed to body surface area-was calculated (LVMI). LVH was set as an LVMI >116g/m2 or 96 g/m2 in men and women, respectively. The ratio of early transmitral peak velocity (E) to the mitral annular early diastolic velocity (Em) was used as an approximation of mean left atrial pressure (E/Em).
UA median (interquartile range): 5.4(2) mg/dl independently predicted E/Em (adjusted coefficient: 1.01, p =0.026) while an interaction term between gender and UA was no significant (p=0.684). An ordinal score of DD was calculated taking into account increased E/Em, left atrium dilatation and LVH. Women with increased UA had 254% increased odds (adjusted OR=2.54, p=0.005) to be classified in the upper range of the DD score.
In hypertensive subjects without HF, UA is independently associated with the presence of DD in both genders and correlates with its severity in women. Further prospective studies are warranted to evaluate the association of UA with adverse cardiovascular outcomes in high-risk populations such as HF with pEF.
Cardiac performance depends on optimum ventriculoarterial coupling which is impaired in patients with heart failure (HF). Galectin-3 is a mediator of myocardial fibrosis and remodeling, and is ...associated with clinical status in patients with chronic HF. We examined the association of arterial stiffness with galectin-3 levels in patients with HF of ischemic etiology.
We consecutively enrolled 40 patients with stable ischemic HF and reduced ejection fraction. Central aortic stiffness was evaluated non-invasively by measuring carotid femoral pulse wave velocity (PWV). Among other factors, serum levels of galectin-3 and b-type natriuretic peptide (BNP) were measured.
The median galectin-3 levels in our study population were 12.9 (10.8-18.7) ng/ml and the mean PWV was 9.31±2.79 m/sec. There was significant association of galectin-3 levels with age (r=0.48, p=0.003), creatinine clearance (r=-0.66, p<0.001) and BNP levels (r=0.36, p=0.05). There was a significant association of galectin-3 levels with PWV (r=0.37, p=0.03) and patients with PWV above median also had significantly increased levels of galectin-3 compared with patients with lower values of PWV 16.1(11.8-25.2) vs. 12.1(10.5-14) ng/ml, p=0.03.
We found an association of arterial stiffness and PWV with galectin-3 levels in patients with chronic HF of ischemic etiology. These findings suggest a pathway driving arterial stiffening and myocardial remodelling in HF. This may provide insight into the mechanism determining prognosis and clinical status of patients with HF.
The sex-specific effect of skeletal muscle mass (SMM) index (SMI) on 4-year first fatal/non-fatal cardiovascular disease (CVD) event in free-of-disease individuals was examined. In 2009,
= 1411 ...inhabitants (mean age = 64(12)) from Ikaria were selected. Follow-up was performed in 2013. SMI was created to reflect SMM through appendicular skeletal muscle mass (indirectly calculated through formulas) divided by body mass index (BMI). Fifteen and six tenths percent of participants exhibited CVD (19.8% in men/12% in women, p = 0.002). Significant U-shape trends were observed in participants >65 years old and women irrespective to age confirmed through multi-adjusted Cox regression analysis; in age >65 years, Hazard Ratio (HR)
= 0.80, 95% Confidence Interval (95%CI) (0.45, 0.96) and in women HR
= 0.71, 95% CI (0.33, 0.95), while, as for the 3rd SMI tertile, no significant trends were observed. Mediation analysis revealed that mediators of the aforementioned associations in men were the arterial distensibility and total testosterone, while, in women, inflammation, insulin resistance, and arterial distensibility. High SMM accompanied by obesity may not guarantee lower CVD risk. Specific cardiometabolic factors seem to explain this need for balance between lean and fat mass.
Sex differences in aging manifest in disparities in disease prevalence, physical health, and lifespan, where women tend to have greater longevity relative to men. However, in the Mediterranean Blue ...Zones of Sardinia (Italy) and Ikaria (Greece) are regions of centenarian abundance, male-female centenarian ratios are approximately one, diverging from the typical trend and making these useful regions in which to study sex differences of the oldest old. Additionally, these regions can be investigated as examples of healthy aging relative to other populations. DNA methylation (DNAm)-based predictors have been developed to assess various health biomarkers, including biological age, Pace of Aging, serum interleukin-6 (IL-6), and telomere length. Epigenetic clocks are biological age predictors whose deviation from chronological age has been indicative of relative health differences between individuals, making these useful tools for interrogating these differences in aging. We assessed sex differences between the Horvath, Hannum, GrimAge, PhenoAge, Skin and Blood, and Pace of Aging predictors from individuals in two Mediterranean Blue Zones and found that men displayed positive epigenetic age acceleration (EAA) compared to women according to all clocks, with significantly greater rates according to GrimAge (β = 3.55;
= 1.22 × 10
), Horvath (β = 1.07;
= 0.00378) and the Pace of Aging (β = 0.0344;
= 1.77 × 10
). Other DNAm-based biomarkers findings indicated that men had lower DNAm-predicted serum IL-6 scores (β = -0.00301,
= 2.84 × 10
), while women displayed higher DNAm-predicted proportions of regulatory T cells than men from the Blue Zone (
= 0.0150, 95% Confidence Interval 0.00131, 0.0117, Cohen's d = 0.517). All clocks showed better correlations with chronological age in women from the Blue Zones than men, but all clocks showed large mean absolute errors (MAE >30 years) in both sexes, except for PhenoAge (MAE <5 years). Thus, despite their equal survival to older ages in these Mediterranean Blue Zones, men in these regions remain biologically older by most measured DNAm-derived metrics than women, with the exception of the IL-6 score and proportion of regulatory T cells.
The real-world implementation of heart failure (HF) guidelines remains unclear. Our present systematic review and meta-analysis aimed to examine the rate of HF patients receiving guideline-directed ...treatment to identify the proportion of under-treatment patients and those who are treated with optimal doses, to evaluate the correlation of under-treatment patients' characteristics with the prescribed therapy, and finally, to evaluate the combined effect of the above on incidental mortality and rehospitalization. We conducted a systematic review of the literature indexed in Medline. We screened 1224 papers and excluded 1166 as they did not meet the inclusion criteria. Of the remaining 58 papers, which were evaluated by studying the full text, 11 papers that referred to 45866 patients were finally studied in this work. Angiotensin-Converting-Enzyme Inhibitor (ACEI) and Angiotensin II-Receptor Blocker (ARB) use was estimated to be 80.9% (95% CI: 73.9%, 86.4%), β-blockers’ use was 78% (95% CI: 70.4%, 84.1%), Mineralocorticoid Receptor Antagonists' use was 47.4% (95% Cl 41.6%, 53.4%), and cardiac resynchronization therapy's use was 5.8% (95% Cl 3.4%, 9.6%). Meta-regression analysis showed that prescription of more than the half of target dose of ACEI/ARBs was found to be associated with reduced all-cause mortality (Z = −3.61, P = 0.0003), while the relationship with β-blockers was borderline (Z = −1.56, P = 0.11). A satisfactory adherence to the prescription of guideline-recommended treatment in patients with HF was observed. However, the under titration of the life-saving HF drugs need to be improved as only ultimate adherence to guideline-directed treatments may lead to the reduction of HF burden.
