Objective. To examine the frequency and patterns of association of cardiovascular risk factors with atherosclerosis in five different arterial territories at post-mortem in Mexico City.Methods. We obtained five arterial territories arteries (circle of Willis, coronary, carotid, renal, and aorta) of 185 men and women 0 to 90 years of age who underwent autopsy at the Medical Forensic Service of Mexico City. We determined the prevalence and extent of atherosclerotic lesions by histopathology according to the classification of the American Heart Association as early (types I–III) and advanced (types IV–VI), and according to the degree of stenosis and correlated with cardiovascular risk factors.Results. Atherosclerotic lesions were identified in at least one arterial territory in 181 subjects (97.8%), with involvement of two ore more territories in 178 subjects (92.2%). Advanced lesions were observed in 36% and 67% of subjects under 15 and between 16 and 35 years, respectively. Any degree of atherosclerosis was associated with the presence of diabetes mellitus, hypertension, overweight, obesity, and smoking, and to a greater extent with the presence of two or more risk factors (P<0.001). However, emerging and advanced athersoclerosis was observed in 53% and 20% people with no risk factors.Conclusions. The study shows a high prevalence of atherosclerosis in all age groups and both sexes. There is considerable development of atherosclerotic disease in subjects without known risk factors.

Background: Coronary artery disease (CAD) is the most frequent cause of ST-segment elevation myocardial infarction (STEMI). Etiopathogenic and prognostic characteristics in young patients may differ from older patients and young women may present worse outcomes than men. We aimed to evaluate the clinical characteristics and prognosis of men and women with premature STEMI. Methods: A total 1404 consecutive patients were referred to our institution for emergency cardiac catheterization due to STEMI suspicion (1 January 2014–31 December 2018). Patients with confirmed premature (<55 years old in men and <60 in women) STEMI (366 patients, 83% men and 17% women) were included (359 atherothrombotic and 7 spontaneous coronary artery dissection (SCAD)). Results: Premature STEMI patients had a high prevalence of classical cardiovascular risk factors. Mean follow-up was 4.1 years (±1.75 SD). Mortality rates, re-hospitalization, and hospital stay showed no significant differences between sexes. More than 10% of women with premature STEMI suffered SCAD. There were no significant differences between sexes, neither among cholesterol levels nor in hypolipemiant therapy. The global survival rates were similar to that expected in the general population of the same sex and age in our region with a significantly higher excess of mortality at 6 years among men compared with the general population. Conclusion: Our results showed a high incidence of cardiovascular risk factors, a high prevalence of SCAD among young women, and a generally good prognosis after standardized treatment. During follow-up, 23% suffered a major cardiovascular event (MACE), without significant differences between sexes and observed survival at 1, 3, and 6 years of follow-up was 96.57% (95% CI 94.04–98.04), 95.64% (95% CI 92.87–97.35), and 94.5% (95% CI 91.12–97.66). An extra effort to prevent/delay STEMI should be invested focusing on smoking avoidance and optimal hypolipemiant treatment both in primary and secondary prevention.

Introduction: There are five different definitions of prediabetes currently used in clinical practice. How cardiovascular risk may differ by these different definitions of prediabetes and whether trends in cardiovascular risk in persons with prediabetes have changed over time is largely uncharacterized. Hypothesis: We expect the prevalence of cardiovascular risk factors will vary by prediabetes definition and will be highest among those who meet clinical definitions with higher cutoff values. We hypothesize awareness, treatment and control of hypertension and hypercholesterolemia have increased over time among those with prediabetes. Methods: We analyzed data for adults ages ≥ 20 years from the 1999-2014 National Health and Nutrition Examination Survey (NHANES). We used calibrated HbA1c and FPG values to estimate prediabetes prevalence. We examined the prevalence and trends of hypertension and hypercholesterolemia among those who met each clinical definition of prediabetes, as well as awareness, treatment, and control. Results: The prevalence of prediabetes by each definitions remained stable across survey years. The prevalence, awareness, treatment, and control of hypertension and hypercholesterolemia by clinical definition modestly increased over time. Conclusion: The prevalence of hypertension and hypercholesterolemia was higher among individuals who met HbA1c-based definitions of prediabetes than other measures and was highest when more restrictive criteria for prediabetes were used. Awareness, treatment, and control of cardiovascular risk factors increased over time by any definition, but the high prevalence of cardiovascular risk factors highlights the need for improvement in risk factor management in people with prediabetes.

Abstract Abstract 3854 Increasing age is a well-recognised risk factor for thrombotic events in patients with Essential Thrombocythemia (ET): however, few data exist on the role of other clinical and biological features in different age groups. To address this issue, we analysed retrospectively 1090 ET patients (M/F 403/687, median age 63 years, IR 17 – 96) diagnosed at 11 Hematological Institutions in the Lazio region from 1980 to 2010 and with a median period of follow-up of 84 months (IR 1 – 371). Based on the commonly adopted age threshold, 480 patients (44 %) were < 60 years (Group A) and 610 (56 %) were ≥ 60 years (Group B). Clinical and biological features as well as cardiovascular risk factors analyzed for the impact on the thrombotic risk in the two age groups are reported in the Table.Group A < 60 yearsGroup B ≥ 60 yearsPutative risk factorsRisk ratio (95% CI)P valueRisk ratio (95% CI)P valueM/F167/3132.68 (1.03–6.94)0.0029236/3741.12 (0.17–2.59)0.73WBC median (range) x 109/l8.9 (4.29–22.35)0.387 (0.149–1,004)0.06458.9 (1.2–57.7)0.79 (0.41–1.47)0.445PLTS median (range) x 109/l837 (451–3582)0.37 (0.258–1.70)0.66802 (450–3104)0.52 (0.28–0.99)0.0052Hb median, g/dL (range)14.1 (6.0–18.4)0.86 (0.33–2.24)0.76914.0 (7.0–17.8)0.87 (0.45–1.67)0.674*JAK-2 mutational status: wild type/mutated (%)53.2/46.81.57 (0.50–4.87)0.4434.1/65.90.498 (0.17–1.48)0.209Previous thrombotic events: n° (%)· All events72 (15)2.18 (0.59–7.96)0.12149 (24.4)3.01 (1.38–6.57)0.0004· within 24 months from diagnosis48 (10)1.43 (0.19–10.4)0.7464 (10.5)0.506 (0.18–1.39)0.189· within 60 months from diagnosis60 (12.5)NA0.5191 (14.9)0.323 (0.11–0.95)0.023Cardiovascular risk factors: Y/N %○ Arterial hypertension41.7/58.31.68(0.64–4.36)0.2880.7/19.30.96 (0.36–2.57)0.935○ Diabetes10.2/89.81.11 (0.23–5.15)0.8925.0/75.01.09 (0.38–3.11)0.86○ Smoking attitude45.6/54.42.78 (1.01–7.65)0.06758.3/41.71.04 (0.35–3.09)0.94○ Hyperlipidemia31.0/69.03.11(0.917–10.592)0.03951.6/48.42.31 (0.70–7.55)0.203 In Group A, 39 patients (8.1%) had at least one thrombotic event during follow-up; there were 20 (51.3%) arterial thrombosis and 19 (48.7%) venous thrombosis. In Group B, 63 patients (10.3%) had at least one thrombotic event during follow-up; there were 38 (69.4%) arterial thromboses and 25 (39.6%) venous thromboses. In group A univariate analysis for thrombosis-free survival performed by Kaplan-Meier method, disclosed a significant impact of male gender (p=0.0029, CI 1.03–6.94, HR 2.68), > 2 cardiovascular risk factors (p=0.0002, CI 1.87 – 190, HR 18.94) and isolated hyperlipidemia (p=0.039, CI 0.917 – 10.59, HR 3.11), while previous thrombotic events had no significant impact (p=0.27). By contrast, the presence of a previous thrombotic event was the only feature with a significant impact on thrombotic risk in Group B (p=0.0004, CI 1.38 – 6.55, HR 3.01). WBC and PLTS values at different cut-off levels as well as JAK-2 mutational status did not have any impact on thrombosis in either age groups. However, in group B, we observed a trend (p=0.052, CI 0.28–0.99, HR 0.52) towards a protective effect of higher PLTS values (> 800 × 109/l). In conclusion, our data seem to reinforce the need of a different thrombotic risk assessment in distinct age groups: in particular, younger patients could benefit from early recognition and treatment of well-known cardiovascular risk factors. Disclosures: No relevant conflicts of interest to declare.

Cardiovascular diseases (CVD) are becoming a serious health issue across the world and conventional risk factors are associated with lifestyle behaviours in all age groups. According to WHO, heart diseases are rapidly increasing in India and it is noted that CVD is not having any boundaries in terms of sex, socioeconomic or geography. The present study is aimed to determine the awareness of cardiovascular risk factors among working women. Self-administered questionnaire was prepared based on cardiovascular risk factors and circulated through an online survey link. The sample size was about 109 working women. The purpose of the study was explained in detail to the participants. The collected data were statistically analyzed using SPSS software. 89.9% of the population thought that working women are more prone to cardiovascular risk factors and 10.1% thought that working women are not prone to CVDs. 60.6% of the participants responded that PCOS could be a risk factor and remaining 39.4% responded that it is not a risk factor for CVD. The entire population answered that a healthy lifestyle and diet could reduce the risk of CVD. The Pearson Chi-square analysis showed that there is no association between the age group of the respondents and awareness of cardiovascular risk factors. To conclude, the awareness of the cardiovascular risk factors among working women was satisfactory.

This study was conducted to evaluate the waist circumference (WC) cut-off points to predict cardiovascular risk factors in the overweight Tehranian population. Anthropometric measures, blood pressure, and biochemical analyses were evaluated for the 15,005 participants of the Tehran Lipid and Glucose Study. Three thousand sixty-five subjects aged 18–74 years with a body mass index of 25–29.9 were enrolled in this study. Abdominal obesity was defined as WC ≥ 102 cm for men and ≥ 88 cm for women. Sensitivity of WC ≥ 102 cm to detect various cardiovascular risk factors for men aged 35–54 years was between 5% and 14%, and for men aged 55–74 years, was between 12% and 19%. The specificity of this cut-off point was between 93% and 98% and between 86% and 96% for corresponding age-categories, respectively. WC ≥ 88 cm had a sensitivity of between 28% and 41% for identifying cardiovascular risk factors in women aged 18–34 years. Sensitivity tended to increase with age and specificity tended to decrease with age in both genders. These cut-off points had the highest positive predictive value for the more prevalent risk factors in both genders. The negative predictive values were different for various risk factors among age groups. The classic cut-off points of WC failed to provide adequate evidence for the use of WC in detecting cardiovascular risk factors. Further studies should be conducted to determine optimal WC cut-off points for Iranians.
